Conversation Analysis shows the evidence of the social nature of people’s action including talk-in-interaction from a micro-level perspective. The method for basing its analysis on the authentic data rather than the retrospective interviews for gain⁃ing the participants’perception makes it unique in discovering the emic perspective of the social interaction. CA, often called as a“micro”methodology, provides theoretical insights and useful analytical tool for exploring the interaction in classrooms.

Full Text Available This article provides a summary of some of the key ideas of Seedhouse (2004. The study applies Conversation Analysis (CA methodology to an extensive and varied database of language lessons from around the world and attempts to answer the question ‘How is L2 classroom interaction organised?’ The main thesis is that there is a reflexive relationship between pedagogy and interaction in the L2 classroom. This means that there is a two-way, mutually dependent relationship. Furthermore, this relationship is the foundation of the organisation of interaction in L2 classrooms. The omnipresent and unique feature of the L2 classroom is this reflexive relationship between pedagogy and interaction. So whoever is taking part in L2 classroom interaction and whatever the particular activity during which the interactants are speaking the L2, they are always displaying to one another their analyses of the current state of the evolving relationship between pedagogy and interaction and acting on the basis of these analyses. So interaction in the L2 classroom is based on the relationship between pedagogy and interaction. Interactants are constantly analysing this relationship and displaying their analyses in their talk. An example of data analysis is provided, including discussion of socially distributed cognition and learning.
Research shows that various stereotypes about science and science learning, such as science being filled with hard and dry content, laboratory experiments, and male-dominated work environments, have resulted in feelings of distance from science in students' minds. This study explores children's experiences of science learning and science identity. It asks how children conceive of doing science like scientists and how they develop views of science beyond the stereotypes. This study employs positioning theory to examine how children and their teacher position themselves in science learning contexts and develop science identity through classroom interactions. Fifteen students in grades 4-6 science classrooms in Western Canada participated in this study. Classroom activities and interactions were videotaped, transcribed, and analysed to examine how the teacher and students position each other as scientists in the classroom. A descriptive explanatory case analysis showed how the teacher's positioning acted to develop students' science identity with responsibilities of knowledge seeking, perseverance, and excitement about science.

Economics is often taught at a level of abstraction that can hinder some students from gaining basic intuition. However, lecture and textbook presentations can be complemented with classroom exercises in which students make decisions and interact. The approach can increase interest in, and decrease skepticism about, economic theory. This feature offers short descriptions of classroom exercises for a variety of economics courses, with something of an emphasis on the more popular undergraduate ...

Peer Instruction (PI) and Just-in-Time-Teaching (JiTT) have been shown to increase both students' conceptual understanding and problem-solving skills. However, the time investment for the instructor to prepare appropriate conceptual questions and manage student JiTT responses is one of the main implementation hurdles. To overcome this we have developed the Interactive Learning Toolkit (ILT), a course management system specifically designed to support PI and JiTT. We are working to integrate the ILT with a fully interactive classroom system where students can use their laptops and smartphones to respond to ConcepTests in class. The goal is to use technology to engage students in conceptual thinking both in and out of the classroom.

Our expanded multi-site study on active learning classrooms supported by Learning Assistants (LAs) aims to understand the connections between three classroom elements: the activity, student learning, and how LAs support the learning process in the classroom. At FIU, LAs are used in a variety of active learning settings, from large auditorium settings to studio classroom with movable tables. Our study uses the COPUS observation protocol as a way to characterize LAs behaviors in these classrooms. With a focus on LA-student interactions, our analysis of how LAs interact with students during a 'learning session' generated new observational codes for specific new categories of LA roles. Preliminary results show that LAs spend more time interacting with students in some classes, regardless of the classroom setting, while in other classrooms, LA-student interactions are mostly brief. We discuss how LA-student interactions contribute to the dynamics and mechanism of the socially shared learning activity.

Large-scale audiovisual data that measure group learning are time consuming to collect and analyze. As an initial step towards scaling qualitative classroom observation, we qualitatively coded classroom video using an established coding scheme with and without its audio cues. We find that interrater reliability is as high when using visual data only—without audio—as when using both visual and audio data to code. Also, interrater reliability is high when comparing use of visual and audio data to visual-only data. We see a small bias to code interactions as group discussion when visual and audio data are used compared with video-only data. This work establishes that meaningful educational observation can be made through visual information alone. Further, it suggests that after initial work to create a coding scheme and validate it in each environment, computer-automated visual coding could drastically increase the breadth of qualitative studies and allow for meaningful educational analysis on a far greater scale.

Full Text Available In recent times, the traditional interaction structures of English both language classrooms and roles of teachers and students are gradually changing. This marks the shift from the teacher-centered classrooms to student-centered classrooms; moving towards ‘student-centered learning’ and‘collaborative working modes’. The contemporary educational world views teachers and students as communicators. In such situations students get more opportunity to ‘participate’, ‘observe’, ‘reflect on’ and ‘practice social ways’. These opportunities expose the students to a more ‘meaning-making’ and ‘knowledge construction processes’. The shift from traditional teaching and learning process to the contemporary one has posed great challenges for teachers, who are always working under pressure to complete the syllabus designed for the academic year. In such a situation it is very important to ascertain if this idea of student-centered classroom is present in the recent classroom. Educationally oriented research into classroom interaction makes it essential for further studies into the classroom interaction in the modern classroom. Hence, this study aims to observe the interaction process that takes place in English classrooms of four government schools in Hilla (Centre of Babylon Governorate. This paper also suggests measures to improve classroom interaction and language learning in the English classes. The main findings from the study are as follows: (a the classroom interaction is teacher-centered, (b teachers partially facilitate learning, the classrooms are controlled by teachers (c the ratio of the teacher-talk is more than student-talk."

Full Text Available Research into the emotional experiences of language learners and their impact upon the language-learning process remains relatively undernourished within second language education. The research available focuses primarily on emotions experienced within the classroom, rather than in the daily lives of learners within various social contexts. This article contends that the focus placed upon emotions within the relatively structured environment of the formal classroom is problematic, particularly within an ESL environment, as the target language is more frequently experienced beyond the classroom. Drawing on data collected within Australia, the study explored the emotional experiences of a small cohort of eight university-level ESL learners experienced within their various social interactions beyond the classroom with a specific focus on the emotions of hope, enjoyment and frustration. Semi-structured interviews revealed that their emotional experiences beyond the classroom were particularly intense in comparison to emotional experiences within the formal language-learning classroom.

In this research, we study the use of interactive digital storytelling in teaching microbiology. More specifically, we carried out an exploratory study assessing the effect of using the gamification of an interactive digital storytelling on classroom dynamics and students’ interaction. The results show that the presence of gamification led to an increase in classroom discussions and in students’ engagement with the learning objectives taught by the interactive digital storytelling.
This article discusses the benefits that clinical laboratory science students and instructors experienced through the use of and integration of computer technology, microscopes, and digitizing cameras. Patient specimens were obtained from the participating clinical affiliates, slides stained or wet mounts prepared, images viewed under the microscope, digitized, and after labeling, stored into an appropriate folder. The individual folders were labeled as Hematology, Microbiology, Chemistry, or Urinalysis. Students, after obtaining the necessary specimens and pertinent data, created case study presentations for class discussions. After two semesters of utilizing videomicroscopy/computer technology in the classroom, students and instructors realized the potential associated with the technology, namely, the vast increase in the amount of organized visual and scientific information accessible and the availability of collaborative and interactive learning to complement individualized instruction. The instructors, on the other hand, were able to provide a wider variety of visual information on individual bases. In conclusion, the appropriate use of technology can enhance students' learning and participation. Increased student involvement through the use of videomicroscopy and computer technology heightened their sense of pride and ownership in providing suitable information in case study presentations. Also, visualization provides students and educators with alternative methods of teaching/learning and increased retention of information.

Full Text Available For the past decade, translation learning has become one of the main foci for university language students in Taiwan. However, many studies have shown that translation teachers tend to adopt traditional teaching methods without considering class dynamics and student interactions. This paper therefore looks into the interactions in the researcher’s designed cooperative translation task, the Cooperative Translation Task, to see how these interactions helped or hindered students’ translation learning. A small class of 25 translation students and two translation teachers were participants. Videotaping and interviews were conducted in order to investigate the interaction modes and student participants’ perspectives toward each interaction mode. Six interaction modes were found in this task: within group, between group, translator group and comment-giver group, instructor and students, guest teacher and students, and instructor and guest teacher. Based on the results and participants’ responses, suggested teaching guidelines are provided.

The current study examines the cognitive supports that underlie achievement in science by using a cultural historical framework (L. S. Vygotsky (1934/1986), Thought and Language, MIT Press, Cambridge, MA.) and the activity setting (AS) construct (R. G. Tharp & R. Gallimore (1988), Rousing minds to life: Teaching, learning and schooling in social context, Cambridge University Press, Cambridge, MA.) with its five features: personnel, motivations, scripts, task demands, and beliefs. Observations were made of the classrooms of seventh-grade science students, 32 of whom had participated in a prior achievement-related parent-child interaction or home study (P. R. Portes, M. F. Zady, & R. M. Dunham (1998), Journal of Genetic Psychology, 159, 163-178). The results of a quantitative analysis of classroom interaction showed two features of the AS: personnel and scripts. The qualitative field analysis generated four emergent phenomena related to the features of the AS that appeared to influence student opportunity for conceptual development. The emergent phenomenon were science activities, the building of learning, meaning in lessons, and the conflict over control. Lastly, the results of the two-part classroom study were compared to those of the home science AS of high and low achievers. Mismatches in the AS features in the science classroom may constrain the opportunity to learn. Educational implications are discussed.
Full Text Available Triadic dialogue, the Initiation, Response, Evaluation sequence typical of teacher /student interactions in classrooms, has long been identified as a barrier to students’ access to learning, including science learning. A large body of research on the subject has over the years led to projects and policies aimed at increasing opportunities for students to learn through interactive dialogue in classrooms. However, the triadic dialogue pattern continues to dominate, even when teachers intend changing this. Prior quantitative research on the subject has focused on identifying independent variables such as style of teacher questioning that have an impact, while qualitative researchers have worked to interpret the use of dialogue within the whole context of work in the classroom. A recent paper offers an alternative way to view the triadic dialogue pattern and its origin; the triadic dialogue pattern is an irreducible social phenomenon that arises in a particular situation regardless of the identity of the players who inhabit the roles in the turn-taking sequence (Roth & Gardner, 2012. According to this perspective, alternative patterns of dialogue would exist which are alternative irreducible social phenomena that arise in association with different situations. The aim of this paper is to examine as precisely as possible, the characteristics of dialogue patterns in a seventh-eighth grade classroom during science inquiry, and the precise situations from which these dialogue patterns emerge, regardless of the staffing (teacher or students in the turn-taking sequence. Three different patterns were identified each predominating in a particular situation. This fine-grained analysis could offer valuable insights into ways to support teachers working to alter the kinds of dialogue patterns that arise in their classrooms.

Full Text Available Being and becoming is the ultimate objective of any educational enterprise, including language teaching. However, research results indicate seemingly unjustified differences between how females and males are treated by EFL (English as a Foreign Language teachers. The overall aim of this study is to illustrate, analyze, and discuss aspects of gender bias and gender awareness in teacher–student interaction in the Iranian college context. To this end, teacher–student interactions of 20 English teachers and 500 students were investigated from the perspective of gender theory. The data were obtained via classroom observations, a seating chart and the audio-recording of all classroom interactions during the study. The findings, obtained from the quantitative descriptive statistics and chi-square methods, as well as the qualitative analysis by way of open and selective coding, uncovered that there were significant differences in the quantity and quality of the interaction for females and males in almost all categories of interaction. The study also revealed teachers’ perception of “gender,” the problems they associate with gender, and the attitudes they have to gender issues. Apparently, while positive incentives are able to facilitate learner growth, the presence of any negative barrier such as gender bias is likely to hinder development. This has implications for teachers, and faculty members who favor healthy and gender-neutral educational climate.

Full Text Available The aim of this study was to develop a deep understanding of interaction in language classroom in foreign language context. Interviews, as major instrument, to twenty experienced English language teachers from eight lower secondary schools (SMP were conducted in Jakarta, completed by focus group discussions and class observation/recordings. The gathered data was analyzed according to systematic design of grounded theory analysis method through 3-phase coding. A model of classroom interaction was formulated defining several dimensions in interaction. Classroom interaction can be more comprehended under the background of interrelated factors: interaction practices, teacher and student factors, learning objectives, materials, classroom contexts, and outer contexts surrounding the interaction practices. The developed model of interaction for language classroom is notably to give deep descriptions on how interaction substantially occurs and what factors affect it in foreign language classrooms at lower secondary schools from teachers’ perspectives.

Full Text Available This case study aimed to examine corrective feedback (CF pattern in the interactions of Indonesian EFL (English as Foreign Language classrooms (a speaking and a grammar classrooms which adopt CLT (Communicative Language Teaching. Two lecturers and twenty undergraduate English department students of an A-class university in Indonesia were involved as research participants. The findings revealed that the lecturers employed all types of CF to treat all types of errors. Explicit corrections were dominant in Speaking class as well as other explicit CF; whereas reformulations and prompt were equally distributed. Elicitation was dominant in Grammar class as well as other prompts; meanwhile, explicit and implicit CFs had similar proportion. The lecturers’ preferences were based on their beliefs on how their students learn foreign language and some factors such as the importance of CF to the instructional focus of the lesson, the possibility to generate student’s uptake, and also their empathetic values about students’ current language development. It was concluded that the provisions of CF in EFL classrooms reflect the application of CLT.

Full Text Available Amrita Jesurasa, Kelly Mackenzie, Hannah Jordan, Elizabeth C Goyder School of Health and Related Research (ScHARR, University of Sheffield, Regent Court, Sheffield, UK Background: The “flipped classroom,” a pedagogical model where typical lecture and homework elements are reversed, is being advocated in medical education to support the teaching of a large curriculum. However, research into the use of this model in postgraduate medical education, which requires the application of acquired knowledge, is limited. The aim of this study was to explore the barriers and facilitators to engagement with the flipped classroom model in preparation for the written element of postgraduate membership examinations. Methods: Three focus groups (n=14 were held between February and June 2016. Participants were drawn from a membership examination preparation course, run by the University of Sheffield. Two of the groups (n=10 involved “students” (public health registrars while the other focus group (n=4 was held with “tutors” (experienced registrars and consultants. The focus groups were audiorecorded and transcribed verbatim. Transcripts were thematically analyzed by using both predetermined and emergent themes. Results: Key themes that emerged from the data included variation in learning and teaching styles of individuals as well as the feasibility and flexibility of the overall course design. However, management of students’ expectations was found to be the fundamental factor, which underpinned the engagement. Conclusion: The complex interaction of factors affecting engagement in this study highlights the need to consider the appropriateness of the flipped classroom model. However, this must be balanced by the potential benefits of the approach for delivering a large curriculum. Recognizing the central importance of managing expectations at the outset would be useful when considering this model in postgraduate medical education. Keywords

Since 2005, graduate students in the Brown University Department of Earth, Environmental, and Planetary Studies have volunteered to teach science to second-grade students at Vartan Gregorian Elementary School in Providence, RI. Initially developed to bring science into classrooms where it was not explicitly included in the curriculum, the graduate student-run program today incorporates the Providence Public Schools Grade 2 science curriculum into weekly, interactive sessions that engage the students in hypothesis-driven science. We will describe the program structure, its integration into the Providence Public Schools curriculum, and 3 example lessons relevant to geology. Lessons are structured to develop the students' ability to share and incorporate others' ideas through written and oral communication. The volunteers explain the basics of the topic and engage the students with introductory questions. The students use this knowledge to develop a hypothesis about the upcoming experiment, recording it in their "Science Notebooks." The students record their observations during the demonstration and discuss the results as a group. The process culminates in the students using their own words to summarize what they learned. Activities of particular interest to educators in geoscience are called "Volcanoes!", "The "Liquid Race," and "Phases of the Moon." The "Volcanoes!" lesson explores explosive vs. effusive volcanism using two simulated volcanoes: one explosive, using Mentos and Diet Coke, and one effusive, using vinegar and baking soda (in model volcanoes that the students construct in teams). In "Liquid Race," which explores viscosity and can be integrated into the "Volcanoes!" lesson, the students connect viscosity to flow speed by racing liquids down a ramp. "Phases of the Moon" teaches the students why the Moon has phases, using ball and stick models, and the terminology of the lunar phases using cream-filled cookies (e.g., Oreos). These lessons, among many others
Formal academic education and experience as a nurse are established preparation for the chief nurse executive (CNE) or upcoming nurse leaders. This article proposes that the nurse leader must build on these fundamentals through self-discipline, lifelong learning, and practice. Three critical ingredients are discussed to guide the nurse leader on a life/career for the CNE and the nurse leader at every level. These include fostering relationships, feeding intellectual curiosity, and engaging in self-care practices. These indispensable ingredients of the successful nurse leader serve as an augmentation to formal education and experience for the nurse aspiring to reach the CNE level and beyond as well as for the current CNE mentoring future leaders.

Full Text Available In interaction between teachers and students, there are some approaches that the teachers usually apply in teaching process in the classroom but the case here is what kinds of approaches that the students can appropriate. The approach which is not appropriate in the teaching and learning process will have an impact on development of cognitive, affective, and psychomotor students themselves. One of the existing approaches in teaching is persuasive approach, in which this approach can convince the students to adopt the material.

Background The “flipped classroom,” a pedagogical model where typical lecture and homework elements are reversed, is being advocated in medical education to support the teaching of a large curriculum. However, research into the use of this model in postgraduate medical education, which requires the application of acquired knowledge, is limited. The aim of this study was to explore the barriers and facilitators to engagement with the flipped classroom model in preparation for the written element of postgraduate membership examinations. Methods Three focus groups (n=14) were held between February and June 2016. Participants were drawn from a membership examination preparation course, run by the University of Shef-field. Two of the groups (n=10) involved “students” (public health registrars) while the other focus group (n=4) was held with “tutors” (experienced registrars and consultants). The focus groups were audiorecorded and transcribed verbatim. Transcripts were thematically analyzed by using both predetermined and emergent themes. Results Key themes that emerged from the data included variation in learning and teaching styles of individuals as well as the feasibility and flexibility of the overall course design. However, management of students’ expectations was found to be the fundamental factor, which underpinned the engagement. Conclusion The complex interaction of factors affecting engagement in this study highlights the need to consider the appropriateness of the flipped classroom model. However, this must be balanced by the potential benefits of the approach for delivering a large curriculum. Recognizing the central importance of managing expectations at the outset would be useful when considering this model in postgraduate medical education. PMID:28721116

Conversational prosody or tone of voice (e.g. intonation, pauses, speech rate etc.) plays an essential role in our daily communication. Research studies in various contexts have shown that prosody can function as an interactional device for the management of our social interaction (Hellermann, 2003, Wennerstrom, 2001, Wells and Macfarlane, 1998, Couper-Kuhlen, 1996). However, not much research focus has been given to the pedagogical implications of conversational prosody in classroom teaching...

Full Text Available Traditional designs for most mid-sized college classrooms discourage 1 face-to-face interaction among students, 2 instructor movement in the classroom, and 3 efficient transitions between different kinds of learning activities. An experimental classroom piloted during Spring Semester 2011 at the University of North Carolina at Chapel Hill uses clusters of stationary desks that swivel 360-degrees and aisle space to address these challenges. The findings from a study involving ten courses taught in the room suggest that there is a need for designs that not only promote quality interactions but also facilitate movement between small group work, class discussion, and lecture.

In this study, we seek a better understanding of how individuals and their daily interactions shape and reshape social structures that constitute a classroom community. Moreover, we provide insight into how discourse and classroom interactions shape the nature of a learning community, as well as which aspects of the classroom culture may be consequential for learning. The participants in this study include two teachers who are implementing a new environmental science program, Global Learning through Observation to Benefit the Environment (GLOBE), and interacting with 54 children in an urban middle school. Both qualitative and quantitative data are analyzed and presented. To gain a better understanding of the inquiry teaching within classroom communities, we compare and contrast the discourse and interactions of the two teachers during three parallel environmental science lessons. The focus of our analysis includes (1) how the community identifies the object or goal of its activity; and (2) how the rights, rules, and roles for members are established and inhabited in interaction. Quantitative analyses of student pre- and posttests suggest greater learning for students in one classroom over the other, providing support for the influence of the classroom community and interactional choices of the teacher on student learning. Implications of the findings from this study are discussed in the context of curricular design, professional development, and educational reform. ? 2004 Wiley Periodicals, Inc.

Full Text Available We run a classroom experiment on oligopoly with students enrolled on basic and medium level microeconomics courses. Students compete in a symmetric quantity setting environment. The experiment runs over an entire academic semester and is divided into 20 one-week rounds. We want to explore whether the effect of knowledge and social interaction between players modifies the cooperative and competitive behavior observed in similar experiments run in a lab. Our hypothesis is that players are socially influenced. Hence, individuals adjust behavior in a dynamic way aimed at maximizing profits, but also according to social pressures. Overall, we obtain different learning processes across academic levels and also slightly different behavior from that predicted by economic theory. We argue that students’ utility function depends not only on profit levels but also on social relationships. Moreover, we believe that the effect of reputation plays an important role in our framework.
Hemos llevado a cabo un experimento oligopolístico en el aula con estudiantes pertenecientes a los niveles básico y medio de la asignatura de microeconomía. Los estudiantes compitieron en un mercado donde todos tenían la misma función de costes ofreciendo cantidades de un bien en cada ronda. El experimento tuvo lugar durante un semestre académico completo y fue dividido en 20 rondas de una semana. Se quiere investigar si el efecto del aprendizaje y de la interacción social entre los jugadores modifica el comportamiento competitivo y cooperativo observado en experimentos similares llevados a cabo en un laboratorio. Nuestra hipótesis es que los jugadores están socialmente influenciados. Así pues, los individuos adecúan su comportamiento dinámicamente con el objetivo de maximizar beneficios pero también en concordancia con las presiones sociales. En general, se han observado diferentes procesos de aprendizaje por niveles académicos así como peque

Full Text Available This article explores the relationship between pedagogical beliefs and classroom practice. Two Colombian pre-service primary school language teachers in the final stage of their five-year training programme were the research participants. Interview and classroom observation were the methods used, and content analysis was the analytical approach. It is argued in this study that by comparing the stated beliefs (as articulated in interviews and enacted beliefs (as manifested in classroom interaction, it is possible to gain a fine-grained understanding of the relationship between beliefs and teaching practice. The findings suggested that while there were significant cases of coherence between beliefs and classroom action, there was also evidence of some incongruent relationships.

While virtual learning environments (VLE) can be used in medical education as stand-alone educational interventions, they can also be used in preparation for traditional "face-to-face" training sessions as part of a "flipped classroom" model. We sought to evaluate the introduction of this model in a single module on maxillofacial radiology from a course on trauma skills. Course delegates were randomised into two groups: one was given access to an e-learning resource (test group) and the other attended a traditional didactic lecture (control group). Knowledge and confidence were assessed before and after the course with a 20-question single-best-answer paper and a 10-situation 100mm visual analogue scale (VAS) paper, respectively. All participants were then given free access to the VLE for 30days and were invited to take part in an e-survey. Neither group showed improvements in the single-best-answer scores, but both groups showed comparable improvements in VAS (control: median (range) values improved from 40.8 (17.7-82.5) mm to 62.8 (35.3-88.7) mm, p=0.001; test group: from 47.7 (10.9-58.1) mm to 60.5 (32.4-75.6) mm, p=0.005). Half of the respondents stated that they preferred the "flipped classroom" approach, and 22/22 stated that they would be "likely" or "very likely" to use an e-learning resource with expanded content. The "flipped classroom" approach was well received and there were comparable improvements in confidence. As maxillofacial radiology lends itself to online instruction with its reliance on the recognition of patterns, and problem-based approach to learning, a piloted e-learning resource could be developed in this area.

The purpose of this study is to create an empirically based theoretic model of change of the use and treatment of representations of functions with the use of Connected Classroom Technology (CCT) using data previously collected for the Classroom Connectivity in Promoting Mathematics and Science Achievement (CCMS) project. Qualitative analysis of videotapes of three algebra teachers' instruction focused on different categories thought to influence teaching representations with technology: representations, discourse, technology, and decisions. Models for rating teachers low, medium, or high for each of these categories were created using a priori codes and grounded methodology. A cross case analysis was conducted after the completion of the case studies by comparing and contrasting the three cases. Data revealed that teachers' decisions shifted to incorporate the difference in student ideas/representations made visible by the CCT into their instruction and ultimately altered their orientation to mathematics teaching. The shift in orientation seemed to lead to the teachers' growth with regards to representations, discourse, and technology.

This descriptive study examined classroom activity settings in relation to children's observed behavior during classroom interactions, child gender, and basic teacher behavior within the preschool classroom. 145 children were observed for an average of 80 minutes during 8 occasions across 2 days using the inCLASS, an observational measure that conceptualizes behavior into teacher, peer, task, and conflict interactions. Findings indicated that on average children's interactions with teachers were higher in teacher-structured settings, such as large group. On average, children's interactions with peers and tasks were more positive in child-directed settings, such as free choice. Children experienced more conflict during recess and routines/transitions. Finally, gender differences were observed within small group and meals. The implications of these findings might encourage teachers to be thoughtful and intentional about what types of support and resources are provided so children can successfully navigate the demands of particular settings. These findings are not meant to discourage certain teacher behaviors or imply value of certain classroom settings; instead, by providing an evidenced-based picture of the conditions under which children display the most positive interactions, teachers can be more aware of choices within these settings and have a powerful way to assist in professional development and interventions.

Almost all of the learning paradigms used in machine learning, learning automata (LA), and learning theory, in general, use the philosophy of a Student (learning mechanism) attempting to learn from a teacher. This paradigm has been generalized in a myriad of ways, including the scenario when there are multiple teachers or a hierarchy of mechanisms that collectively achieve the learning. In this paper, we consider a departure from this paradigm by allowing the Student to be a member of a classroom of Students, where, for the most part, we permit each member of the classroom not only to learn from the teacher(s) but also to "extract" information from any of his fellow Students. This paper deals with issues concerning the modeling, decision-making process, and testing of such a scenario within the LA context. The main result that we show is that a weak learner can actually benefit from this capability of utilizing the information that he gets from a superior colleague-if this information transfer is done appropriately. As far as we know, the whole concept of Students learning from both a teacher and from a classroom of Students is novel and unreported in the literature. The proposed Student-classroom interaction has been tested for numerous strategies and for different environments, including the established benchmarks, and the results show that Students can improve their learning by interacting with each other. For example, for some interaction strategies, a weak Student can improve his learning by up to 73% when interacting with a classroom of Students, which includes Students of various capabilities. In these interactions, the Student does not have a priori knowledge of the identity or characteristics of the Students who offer their assistance.

Full Text Available The first session of interaction in the classroom often sets an atmosphere for the entire period of learning. In terms of nurse educator and student nurse neophyte relations, good interaction is essential in helping students to recognise their own responsibilities and to respond positively during the learning process. The purpose of this study was to determine the nurse educators’ and student nurse neophytes’ perceptions of good interaction in the classroom setting. The study attempted to answer the following specific question: ‘What do nurse educators and student nurse neophytes regard as examples of good interaction in the classroom setting?’ The accessible population in this study were all student nurse neophytes registered with the University of Venda for the Baccalaureus Curationis, and nurse educators responsible for teaching first-year student nurses in this programme. The study used probability stratified random sampling to obtain two heterogeneous groups of student participants. Forty first-year student nurses were divided into homogenous subsets of 15 male and 25 female students. A random sampling was conducted to arrive at 10 male and 15 female students. The sampling method relating to nurse educators was purposive sampling. Focus groups were used to interview students using individual in-depth interviews to gather data from nurse educators. Coding was used to organise the data collected during the interviews. The study revealed that nurse educators and student nurse neophytes concur that the ethical behaviours influencing good interaction are respect and support, good communication, honesty and openness. Age, gender and cultural background were also factors. The participants further indicated that good interaction has benefits such as improved co-operation levels, the enhancement of learning, the improvement of pass rates, and a reduction in dropout rates. In conclusion, there is a need for nurse educators and student nurses

The present study compares the highly interactive cloud-classroom (HIC) system with traditional methods of teaching materials science that utilize crystal structure picture or real crystal structure model, in order to examine its learning effectiveness across three dimensions: knowledge, comprehension and application. The aim of this study was to evaluate the (HIC) system, which incorporates augmented reality, virtual reality and cloud-classroom to teach basic materials science courses. The study followed a pretest-posttest quasi-experimental research design. A total of 92 students (aged 19-20 years), in a second-year undergraduate program, participated in this 18-week-long experiment. The students were divided into an experimental group and a control group. The experimental group (36 males and 10 females) was instructed utilizing the HIC system, while the control group (34 males and 12 females) was led through traditional teaching methods. Pretest, posttest, and delayed posttest scores were evaluated by multivariate analysis of covariance. The results indicated that participants in the experimental group who used the HIC system outperformed the control group, in the both posttest and delayed posttest, across three learning dimensions. Based on these results, the HIC system is recommended to be incorporated in formal materials science learning settings.
Full Text Available This article reports a study on teachers’ use of interaction strategies in English Language Teaching (ELT in lower secondary level of education. The study involved eighteen teachers from Lower Secondary Schools in Malang, East Java. Classroom observation was selected as a method in this study by utilizing Self Evaluation Teacher Talk (SETT as the instrument. SETT, developed by Walsh (2006, was adopted as the observation protocol as it characterises teacher-student interaction. Thirty lessons taught by 18 teachers were observed. The findings revealed that much of the teacher student interaction in Lower Secondary Schools centred on the material mode, skill and system mode. The most frequent strategies were initiation response feedback (IRF patterns, display questions, teacher echo, and extended teacher turns, while students’ extended turns were rare. It is argued that in order to improve the Indonesian ELT, there is a need to provide an alternative to ELT classroom interaction. The article concludes by highlighting the importance of adopting some classroom interaction strategies that are more facilitative to students’ oral communicative competence.

Early research exploring teacher expectations concentrated on the dyadic classroom interactions of teachers with individual students. More recent studies have shown whole class factors to have more significance in portraying teachers' expectations. Recently teachers having high or low expectations for all their students have been identified. The aim of the current investigation was to explore whether the classroom exchanges of high- and low-expectation teachers differed substantially and might be considered a mechanism for teachers' expectations. The participants were 12 primary school teachers from eight schools who had been identified as having expectations for their students' learning that were either significantly above or below the children's achievement level. The teachers formed three groups called high-expectation, low-expectation and average-progress teachers. The participants were observed twice in the academic year during half-hour reading lessons. Two people observed each lesson, one completing a structured observation protocol and the other a running record and audiotape. In contrast to the average progress and low expectation teachers, the high-expectation teachers spent more time providing a framework for students' learning, provided their students with more feedback, questioned their students using more higher-order questions, and managed their students' behaviour more positively. There appear to be important differences in the classroom environments for the students of high-expectation, average-progress and low-expectation teachers. The differences apply to both the instructional and socioemotional environments of the classroom. Such disparities may act as mechanisms for teacher expectation effects.

Active-learning environments such as those found in a flipped classroom are known to increase student performance, although how these gains are realized over the course of a semester is less well understood. In an upper-level lecture course designed primarily for biochemistry majors, we examine how students attain improved learning outcomes, as measured by exam scores, when the course is converted to a more active flipped format. The context is a physical chemistry course catering to life science majors in which approximately half of the lecture material is placed online and in-class problem-solving activities are increased, while total class time is reduced. We find that exam performance significantly improves by nearly 12% in the flipped-format course, due in part to students interacting with course material in a more timely and accurate manner. We also find that the positive effects of the flipped class are most pronounced for students with lower grade point averages and for female students. © 2015 D. Gross et al.

Currently, theophylline is being used predominantly as sustained-release capsules or tablets. In the mid-seventies the first preparations for use with a dosage interval of 12 hours (twice-daily preparations) were introduced. Since 1983, theophylline preparations that can be given with an interval of 24 hours (once-daily preparations) have become available. The release of theophylline from some of these products can be influenced (either increased or decreased) by concomitant intake of food. With some preparations the composition of the meal (especially the fat content) has an influence on the degree of effect. The consequence may be an effect on the rate of absorption or on the amount absorbed, or both simultaneously. This could result in an unexpected shift of the plasma theophylline concentration. Such a shift is therapeutically undesirable, because theophylline has a fairly narrow therapeutic range. A review is given of those food interactions with the sustained-release theophylline preparations, both twice-daily and once-daily products, that are currently on the world market. Special attention is paid to the specific (bio)pharmaceutical characteristics of the different products, and to the influence of the composition and timing of the meals. For each preparation the effect of food on the following pharmacokinetic parameters is discussed: area under the plasma concentration-time curve, peak plasma drug concentration and time to reach this peak. Where possible, the results for both adults and children are discussed. There are indications that children are more susceptible to food-effects than adults. The regulatory aspects are mentioned briefly. Clinically important effects of food have been observed with the following twice-daily products: 'Theo-Dur Sprinkle', 'Theolair SR' (= 'Nuelin SR') and 'Theograd'. Pronounced effects could have an even greater impact with once-daily preparations, as the total daily dose will be given at a single time. A particularly

In the spring term of 2010, Oregon State University (OSU) began using a SCALE-UP style classroom in the instruction of the introductory calculus-based physics series. Instruction in this classroom was conducted in weekly two-hour sessions facilitated by the primary professor and either two graduate teaching assistants (GTAs) or a graduate teaching assistant and an undergraduate learning assistant (LA). During the course of instruction, two of the eight tables in the room were audio and video recorded. We examine the practices of the GTAs in interacting with the students through both qualitative and quantitative analyses of these recordings. Quantitatively, significant differences are seen between the most experienced GTA and the rest. A major difference in confidence is also observed in the qualitative analysis of this GTA compared to a less experienced GTA.

With the incorporation in education of Information and Communication Technologies (ICT), especially the Interactive Whiteboard (IWB), emerges the need for a proper teacher training process due to adequate the integration and the didactic use of this tool in the classroom. This article discusses the teachers' perception on the training process for ICT integration. Its main aim is to contribute to the unification of minimum criteria for effective ICT implementation in any training process for active teachers. This case study begins from the development of a training model called Eduticom which was putted into practice in 4 schools in Catalonia, Spain. Findings indicated different teachers' needs such as an appropriate infrastructure, a proper management and a flexible training model which essentially addresses methodological and didactic aspects of IWB uses in the classroom.
Full Text Available The article deals with the concept of a continuum of regulation being also important to understanding Vygotsky’s view of cognitive development which clearly suggests that communicative collaboration with adults or more skilled peers contributes to the development of self-regulation, that is, the capacity for independent problem solving and self-directed activity. Attention is drawn to the fact that in the language classroom, using sociocultural theory and its tenets as a framework, we would see a highly interactive classroom, where the students’ zone of proximal development is identified through strategies such as portfolios, and dialogue journals. Necessity of compiling a textbook based on the above-mentioned principles is stressed.
Full Text Available Discourse features that promote the generation of interactionally modified input and output, such as negotiation for meaning, have been shown to significantly enhance second language acquisition. Research has also identified several characteristics of instructional practices that render them more or less propitious to the generation of these discourse features. While various classroom observation studies have successfully measured the communicative orientation of classroom environments, most of the indicators of interactivity analyzed in those studies were obtained through micro-level discourse analyses and not through macro-level analyses of task-related factors shown to directly influence the interactivity of instructional practices. Such a macro-level scale has potential practical implications for teachers and administrators seeking an efficient tool for assessing and improving the interactivity afforded by a given curriculum. The objective of the present study was therefore to develop macro-level scale to determine the extent to which teachers of French and English as a second language use interaction-friendly instructional practices. Using an observation scheme designed to code data on factors shown to influence interactivity, 63 hours of FSL and ESL classes from secondary schools in the Montreal area were observed and analyzed. Results indicate clear differences between the two groups. While both ESL and FSL classes were less teacher-centered than those observed in previous studies, they were still rated as not-very-interactive. Target language differences showed that the FSL classes were more teacher-centered and characterized by fewer interaction-friendly tasks and activities than the ESL classes. Task characteristics, reasons for ESL and FSL differences and recommendations for improvement are discussed.

The integration of socioscientific issues (SSI) in science education calls for emphasizing dialogic classroom practices that include students' views together with multiple sources of knowledge and diverse perspectives on the issues. Such classroom practices aim to empower students to participate in decision-making on SSI. This can be accomplished by enhancing their independence as learners and positioning them as legitimate participants in societal discussions. However, this is a complex task for science teachers. In this study, we introduce positioning theory as a lens to analyse classroom discourse on SSI in order to enhance our knowledge of the manners by which teachers' interactions with students make available or promote different positions for the students, that is, different parts for the students to play as participants, when dealing with SSI in the classroom. Transcripts of interactions between one teacher and six student groups, recorded during two lessons, were analysed with respect to the positioning of the students as participants in the classroom, and in relation to the SSI under consideration. The results show that the teacher-student interactions made available contrasting student positions. The students were positioned by the teacher or positioned themselves as independent learners or as dependent on the teacher. Furthermore, the students were positioned as affected by the issue but as spectators to public negotiations of the issue. Knowledge about the manner in which teacher-student interactions can function to position students seems important for dialogic classroom practices and the promotion of student positions that sustain the pursuit of intended educational outcomes.
Full Text Available Virtual laboratories, an ICT-based initiative, is a new venture that is becoming more prevalent in universities for improving classroom education. With geographically remote and economically constrained institutes in India as the focus, we developed web-based virtual labs for virtualizing the wet-lab techniques and experiments with the aid of graphics favoured animations, mathematical simulators and remote triggered experimentations. In this paper, we analysed perceived usefulness of Biotechnology virtual labs amongst student groups and its role in improving the student’s performance when introduced as a learning tool in a blended classroom scenario. A pedagogical survey, via workshops and online feedback, was carried out among 600 university-level students and 100 remote users of various Indian universities. Comparing learning groups on usage of blended learning approach against a control group (traditional classroom methods and an experimental group (teacher-mediated virtual labs, our studies indicate augmented academic performance among students in blended environments. Findings also indicated usage of remotely-triggered labs aided enhancing interaction-based lab education enabling anytime-anywhere student participation scenarios.

Effective approaches for teaching vocabulary to various populations of learners is a topic of current research (Barr, Eslami, & Malatesha, 2012) yet little research is dedicated to students with learning disabilities in the science classroom. Within this study the interac-tive word wall was used as a tool to build vocabulary and to encourage usage of new sub-ject-specific terminology. The experiment utilized quasi-experimental pre-post test com-parison group design using interrupted time-series (Johnson & Christiensen, 2007) due to the inability to randomize participants and establish a clear control group. The data was collected across four units of terminology and with a student satisfaction survey. Stu-dents reported at least seventy percent satisfaction with the use of Interactive Word Walls and demonstrated some performance increase in both vocabulary retention and reading comprehension when utilizing Interactive Word Walls.

Full Text Available The searching for a better understanding of the interactive process that is taken place inside a classroom has motivated the development of some researches, willing to visualize its main complex and multiple variables that are established among its members. It is important to mention that such variables should be concerned not only with their cognitive aspect, but the subjective and emotional aspects, as well, since they could represent an obstacle or a tool when dealing with the whole learning process.And based on such concept and the Vigotski´s theory, we have decided to study the main social interactions and the emotions that were released between a Physics Teacher and her students, when teaching the theory of a body in a state of static equilibrium. The outcomes have shown that the teacher should be aware of the emotional aspects regarding the social interaction that are established with and among the students, optimizing in that way the educational resources applied inside the classroom.
Full Text Available Interactive whiteboard (IWB use has been associated with increased student motivation, engagement, and achievement, though many studies ignore the role of the teacher in effecting those positive changes. The current study followed the practice of 28 high school science teachers as they integrated the IWB into their regular classroom activities. The extent of teachers’ adoption and integration fell along a continuum, from the technologically confident “early adopter” to the low-use “resistant adopter.” Patterns of use are explored by extracting data from representative teachers’ practice. Science-specific benefits of IWB use, barriers to integration, and lessons learned for professional development are discussed.
Full Text Available The aim of this study is twofold: firstly, it aims to explore the interactional conditions in terms of democratic qualities constituted in collective writing in a primary school classroom; and secondly, it aims to examine whether a set of deliberative criteria is fruitful as an analytical tool when studying classroom interaction. Theoretically, I turn to New Literacy Studies for understanding the writing classroom as a literacy practice and the actual (collective writing as literacy events. The study has an ethnographic approach in which classroom observations were conducted during a collective writing process involving six nine-year-old children and their teacher. The observations included, two lessons, divided into 3 hours, which were observed, videotaped, and transcribed. The teacher had planned for a strict interactional or didactical order during the collective writing in which the children were to respond individually. However, the children responded in a different manner by starting a vivid dialogue in which they negotiated both the form and the content of the story. The analysis shows some deliberative qualities in this classroom interaction, while some other qualities were not evident. Furthermore, the analysis showed that the set of deliberative criteria was useful in visualizing both existing deliberative qualities in the interaction and the potential for developing such qualities.

Full Text Available The present study aims to examine corrective feedback and learner uptake in classroom interactions. Inspired by Lyster and Ranta’s corrective feedback framework (1997, this study intends to describe and analyze the patterns of corrective feedback utilized by Iranian teachers, and learners' uptake and the repair of those errors. To this aim, 400 minutes of classroom interaction from three elementary EFL classes which comprised 29 EFL learners were audiotaped and transcribed. The learners were within age range of 16-29 and were native speakers of Turkish language. The teachers were within 26-31 age range and had 3-4 years experience of teaching and hold MA degree in TOEFL. Analysis of data constituted the frequency of six different feedback types used by three teachers, in addition distribution of learners' uptake following each feedback type. The findings indicated that among six corrective feedback types, recast was the most frequent feedback utilized by teachers although it did not lead to high amount of learner uptake. Metalinguistic feedback, elicitation and clarification request led to higher level of uptake. It was also found that explicit feedback was more effective than implicit feedback in promoting learner uptake.
Full Text Available The aim of this study is to understand an elementary teachers’ experiences about using interactive whiteboard (IWB in the classroom. Narrative inquiry were adopted to conduct the study. The data were collected through semi-structured interviews with the teacher and analysed through narrative analysis. In the study, two major stories emerged. The first story was about the characteristics and difficulties of being an innovative and transformative teacher. In the second story, the use of technology in the classroom were cited. Second story consisted of such sub-stories as changing student profiles, teaching-learning process, measurement and evaluation process, infrastructural adequacy, stakeholder interaction, facilitator role of the technology and challenges of using IWB in the classroom. In all these stories, the examples and advantages of effective use of IWB in the classroom were explained. We can have the following suggestions from the words of the classroom teacher who has been using various technological tools in his classroom for about 40 years, including 10-year IWB use: Teachers should be open-minded for innovation in the sense of professional development, consider the interests of students, reduce the prejudice about the use of technology, utilize the processes that increase and facilitate the learning.

Flipping the classroom is a pedagogical model that employs easy to use, readily accessible technology based resources such as video lectures, reading handouts, and practice problems outside the classroom, whereas interactive group-based, problem-solving activities conducted in the classroom. This strategy permits for an extended range of learning activities during the session. Using class time for active learning provides greater opportunity for mentoring and peer to peer collaboration. Instead of spending too much time on delivering lectures, class time can best be utilized by interacting with students, discussing their concerns related to the particular topic to be taught, providing real life examples relevant to the course content, challenging students to think in a broader aspect about complex process and encouraging different team based learning activities.

Although scholars have long advocated the use of informational texts in the primary grades, gaps and inconsistencies in research have produced conflicting reports on how teachers used these texts in the primary curriculum, and how primary students dealt with them during instruction and on their own (e.g., Saul & Dieckman, 2005). Thus, to add to research on informational texts in the primary grades, the purpose of this study was to examine: (a) a first-grade teacher's use of science informational trade books (SITBs) in her classroom, (b) the ways students responded to her instruction, and (c) how students interacted with these texts. My study was guided by a sociocultural perspective (e.g., Bakhtin, 1981; Vygotsky, 1978), providing me a lens to examine participants during naturally occurring social practices in the classroom, mediated by language and other symbolic tools. Data were collected by means of 28 observations, 6 semi-structured interviews, 21 unstructured interviews, and 26 documents over the course of 10 weeks. Three themes generated from the data to provide insight into the teacher's and students' practices and interactions with SITBs. First, the first-grade teacher used SITBs as teaching tools during guided conversations around the text to scaffold students' understanding of specialized vocabulary, science concepts, and text features. Her instruction with SITBs included shared reading lessons, interactive read-alouds and learning activities during two literacy/science units. However, there was limited use of SITBs during the rest of her reading program, in which she demonstrated a preference for narrative. Second, students responded to instruction by participating in guided conversations around the text, in which they used prior knowledge, shared ideas, and visual representations (e.g., illustrations, diagrams, labels, and captions) to actively make meaning of the text. Third, students interacted with SITBs on their own to make sense of science, in

Mathematics classroom interaction has often been described as an important context for involving all students. However, this article shows that teacher-student-interaction is still not really in the focus of teachers' attention. Based on classroom video studies, some authors hypothesize that the implicitness of establishing norms and practices is, among others, an obstacle for students with low socio-economic status. The article intends to put this hypothesis into perspective by investigating teachers' and students' focus of attention on classroom interaction in video-stimulated group discussions (six discussions with 5-6 students, four discussions with 5-9 teachers). The data analysis used inductive procedures of category development, frequency analysis, and deeper qualitative analysis of the transcripts. For students' focus of attention, differential patterns could be extrapolated: Whereas students of high socio-economic status seem to be more attentive to teacher's contextual expectations, the students of low socio-economic status seem to be more focused on general norms without taking into account contextual expectations. For the teachers, the analysis shows that interactive mechanisms of teacher-student exchanges in classrooms are usually not in the teachers' focus of attention. Additionally, the teachers address, but rarely problematize the implicitness by which norms and practices are established. Together with the differential findings on students' attention, these findings are discussed with respect to equity concerns and consequences for professional development of teachers.

We show that boys still have a greater access to the space for interaction in science classrooms, which is unexpected since in Sweden today girls perform better in these subjects than boys. Results from video-recorded verbal communication, referred to here as interaction, show that the distribution of teacher-student interaction in the final year of lower secondary school follows the same patterns as in the 1980s. The interaction space for all kinds of talk continues to be distributed according to the two-thirds rule for communication in science classrooms as described by previous research. We also show that the overall interaction space in science classrooms has increased for both boys and girls when talk about science alone is considered. Another finding which follows old patterns is that male teachers still address boys more often than girls. This holds true both for general talk and for talk about science. If a more even distribution of teacher-student interaction is desirable, these results once again need to be considered. More research needs to be undertaken before the association between girls' attitudes and interest in science in terms of future career choice and the opportunity to participate in teacher-student interaction is more clearly understood. Research conducted at Mid Sweden University, Department of Science Education and Mathematics.

The effects of student-faculty interactions in higher education have received considerable empirical attention. However, there has been no empirical study that has examined the relation between student-faculty interaction and college grade point average. This is aimed at identifying the effect of nursing student-faculty interaction outside the classroom on students' semester college grade point average at a public university in Jordan. The research was cross-sectional study of the effect of student-faculty interaction outside the classroom on the students' semester college grade point average of participating juniors and seniors. Total interaction of the students was crucial as it is extremely significant (t = 16.2, df = 271, P ≤ 0.001) in relation to students' academic scores between those students who had ≥70 and those who had <70 academic scores. However, gender differences between students, and other variables were not significant either to affect students' academic scores or students' interaction. This study provides some evidence that student-faculty interactions outside classrooms are significantly associated with student's academically achievements. Copyright © 2011 Elsevier Ltd.

The human brain has evolved for group living . Yet we know so little about how it supports dynamic group interactions that the study of real-world social exchanges has been dubbed the "dark matter of social neuroscience" . Recently, various studies have begun to approach this question by comparing brain responses of multiple individuals during a variety of (semi-naturalistic) tasks [3-15]. These experiments reveal how stimulus properties , individual differences , and contextual factors  may underpin similarities and differences in neural activity across people. However, most studies to date suffer from various limitations: they often lack direct face-to-face interaction between participants, are typically limited to dyads, do not investigate social dynamics across time, and, crucially, they rarely study social behavior under naturalistic circumstances. Here we extend such experimentation drastically, beyond dyads and beyond laboratory walls, to identify neural markers of group engagement during dynamic real-world group interactions. We used portable electroencephalogram (EEG) to simultaneously record brain activity from a class of 12 high school students over the course of a semester (11 classes) during regular classroom activities (Figures 1A-1C; Supplemental Experimental Procedures, section S1). A novel analysis technique to assess group-based neural coherence demonstrates that the extent to which brain activity is synchronized across students predicts both student class engagement and social dynamics. This suggests that brain-to-brain synchrony is a possible neural marker for dynamic social interactions, likely driven by shared attention mechanisms. This study validates a promising new method to investigate the neuroscience of group interactions in ecologically natural settings. Copyright © 2017 The Authors. Published by Elsevier Ltd..

Stanford's Solar Center, in conjunction with the Space, Telecommunications and Radioscience Laboratory and local educators, have developed inexpensive Space Weather Monitors that students around the world can use to track solar-induced changes to the Earth's ionosphere. Through the United Nations Basic Space Science Initiative (UNBSSI) and the IHY Education and Public Outreach Program, our Monitors have been designated for deployment to 191 countries for the International Heliophysical Year, 2007. In partnership with Chabot Space and Science Center, we are designing and developing classroom and educator support materials to accompany distribution of the monitors worldwide. Earth's ionosphere reacts strongly to the intense x-ray and ultraviolet radiation released by the Sun during solar events and by lightning during thunderstorms. Students anywhere in the world can directly monitor and track these sudden ionospheric disturbances (SIDs) by using a VLF radio receiver to monitor the signal strength from distant VLF transmitters and noting unusual changes as the waves bounce off the ionosphere. High school students "buy in" to the project by building their own antenna, a simple structure costing little and taking a couple hours to assemble. Data collection and analysis are handled by a local PC. Stanford is providing a centralized data repository where students and researchers can exchange and discuss data. Chabot Space & Science Center is an innovative teaching and learning center focusing on astronomy and the space sciences. Formed as a Joint Powers Agency with the City of Oakland (California), the Oakland Unified School District, the East Bay Regional Park District, and in collaboration with the Eastbay Astronomical Society, Chabot addresses the critical issue of broad access to the specialized information and facilities needed to improve K-12 science education and public science literacy. Up to 2,000 K-12 teachers annually take part in Chabot's professional

This commentary reviews research findings of the five papers in the special entitled "School-related Factors in the Development of Bullying Perpetration and Victimization", which represent critical areas that are often overlooked in the literature. First, one paper points to the complex interaction between a genetic disposition for aggression and classroom norms toward aggression. Second, an intervention paper unpacks the underlying mechanisms of an efficacious school-wide bully prevention program by opening the "black box" and testing for mediators. Third, the remaining studies employ a wide range of rigorous designs to identify how teachers' attitudes, behaviors, and classroom practices play a critical role in the prevalence of victimization and bullying in the classroom. Further, teachers' attitudes and behaviors are shown to be predictive of youth's willingness to intervene to assist a peer who is being victimized. Results are situated in what is known about bullying prevention, and how the findings from these studies could maximize the sensitivity of future prevention efforts.

Full Text Available In deprived socio cultural contexts like those characterizing the suburbs of Bogotá, cooperative learning (CL appears as an alternativeto cope with student problems of interpersonal communication and conflict derived largely from gossiping, information distortion, and verbal aggressiveness that result in an inappropriate learning environment. As a result of implementing this action research study with 8th graders in a public school of Usme, in the south east of Bogotá, students’ original negative influence over their peers turned into positive mediation, featured by peer monitoring, peer correction, and peer feedback. Such a change, which was evident in class audio and video recordings, as well a ssuccessful CL task development, occurred thanks to the joint establishment of rules for cooperative interaction with their corresponding roles, functions, times, and spaces immersed in the implemented CL structures of interaction. This way, students raised awareness of the crucial factors involved in effective oral communication and the importance of reporting information accurately for well-informed opinions and decisions. Students’ improvement in the oral communication processes contributed significantly to a better classroom social environment for learning.

The National Research Council's (NRC) statement and description of features of settings that have value for positive youth development have been of great importance in shifting discourse toward creating programs that capitalize on youth motivations toward competence and connections with others. This assets-based approach to promote development is consistent with the Classroom Assessment Scoring System (CLASS) framework for measuring and improving the quality of teacher-student interactions in classroom settings. This chapter highlights the similarities between the CLASS and NRC systems and describes the CLASS as a tool for standardized measurement and improvement of classrooms and their effects on children. It argues that the next important steps to be taken in extending the CLASS and NRC frameworks involve reengineering assessments of teacher and classroom quality and professional development around observations of teachers' performance. This might include using observations in policies regarding teacher quality or a "highly effective teacher" that may emanate from the reauthorization of No Child Left Behind and moving away from a course or workshop mode of professional development to one that ties supports directly to teachers' practices in classroom settings.

We examined the peer interactions and academic engagement of 23 middle and high school students with developmental disabilities within inclusive academic and elective classrooms. The extent to which students with and without disabilities interacted socially was highly variable and influenced by instructional format, the proximity of general and special educators, and curricular area. Peer interactions occurred more often within small group instructional formats, when students were not receiving direct support from a paraprofessional or special educator, and in elective courses. Academic engagement also varied, with higher levels evidenced during one-to-one or small group instruction and when in proximity of general or special educators. Implications for designing effective support strategies for students with autism and/or intellectual disability within general education classrooms are discussed.

Roussel De Carvalho uses the notion of superdiversity to draw attention to some of the pedagogical implications of teaching science in multicultural schools in cosmopolitan cities such as London. De Carvalho makes the case that if superdiverse classrooms exist then Science Initial Teacher Education has a role to play in helping future science teachers to become more knowledgeable and reflective about how to teach school students with a range of worldviews and religious beliefs. The aim of this paper is to take that proposition a step further by considering what the aims and content of a session in teacher education might be. The focus is on helping future teachers develop strategies to teach school students to think critically about the nature of science and what it means to have a scientific worldview. The paper draws on data gathered during an interview study with 28 students at five secondary schools in England. The data was analysed to discover students' perceptions of science and their perceptions of the way that science responds to big questions about being human. The findings are used to inform a set of three strategies that teachers could use to help young people progress in their understanding of the nature of science. These strategies together with the conceptual framework that underpins them are used to develop a perspective on what kinds of pedagogical content knowledge teacher education might usefully provide.

The research reported in this inquiry consisted of the application of two classroom learning environment questionnaires developed in a Western context to a culturally diverse context, namely, the Pacific Islands. The College and University Classroom Environment Inventory (CUCEI) and Questionnaire on Teacher Interaction (QTI) instruments were administered to intact classes of first- and second-year science students ( n= 257) at a regional university in the Pacific Islands, containing a total of 12 ethnicities. The data reveal that the QTI instrument holds good reliability for all scales, whereas the CUCEI holds reliability for only two scales. This may be due to the simple nature of the questions on the QTI whereas the questions on the CUCEI require more interpretation, the latter exacerbated by the fact that English is a second or third language for most participants. Surprisingly, there were few differences in perceptions of teacher student interaction based on ethnicity, but substantial differences based on gender. As reported in previous classroom environment research at the secondary school level, in this study, females perceived their environment more favourably than males. The data for the QTI reveal that the students perceive their classrooms to be highly teacher dominated, consistent with previous naturalistic studies of secondary schools and exploratory studies at the tertiary level in Fiji. Since almost all the graduates from this institution become science teachers, a cycle is completed.

Collaboration is an important career skill and vital to student understanding of the social aspects of science, but less is known about relationships among collaborative-learning strategies, classroom climate, and student learning. We sought to increase the collaborative character of introductory undergraduate laboratory classrooms by analyzing a 9-week intervention in 10 classrooms ( n = 251) that participated in cooperative-learning modules (promoting interdependence via a modified jigsaw technique). Students in an additional 10 classrooms ( n = 232) completed the same material in an unstructured format representative of common educational practice. Results showed that, when between-class variance was controlled for, intervention students did not score higher on weekly quizzes, but science interest and prior science experience had a reduced relationship to quiz performance in intervention classrooms. Also, intervention classrooms showed increased collaborative engagement at both whole-class and individual levels (24 students at three time points), but the intervention was only one of several factors found to account for late-intervention classroom collaborative engagement (prosocial behavior and discussion practices). Taken together, findings suggest that integrating interdependence-based tasks may foster collaborative engagement at both small-group and whole-classroom levels, but by itself may not be enough to promote increased student achievement.

Full Text Available The National Program for Access to Secondary Education and Employment (Pronatec, created by the federal government has offered, in recent years, training in technical courses at post-secondary level for young people and adults inserted in the educational system and who were attending or finishing high school, including the Youth and Adult Education system (EJA. Thus, some classes of technical courses presented a varied profile of students from teenagers who attend public schools and even older adults who are returning to school after years of absence from the education system. The present study analyzed four groups of students aged between 15 and 63 years. This age difference, how the oldest students use or not technology and the kind of relationship between the students in the classroom raised questions about their relationship on social networks. This network usage by the students significantly influenced the pedagogical practice during the course, considering that the students asked the teacher to use it as a teaching and learning resource. The students transit from reality to virtual world with the naturalness of people who were born inserted in this context of interactions mediated by technology.

This research was conducted by an urban middle school science teacher who sought to investigate the effects of self-assessment on student performance. A group of students were asked to give themselves a score on each learning target assessed in class and to provide evidence for their decision. Student self-assessment scores were compared to scores given by the teacher to see if students who accurately assessed their own learning scored higher on final assessments than students who did not. Assessment scores between groups of students who completed the self-assessment preparation and students who did not were also analyzed. The data indicates no correlation between the ability to self-assess and achievement. However, further implications on self-assessment at the secondary level are discussed.

We have conducted a national research study designed to determine the effect of interactive learning strategies on students' conceptual learning in general education astronomy courses (Astro 101). Nearly 4000 students at 31 institutions, (4-year and 2-year) around the country participated in the study. Our results show dramatic improvement in student learning with increased use of interactive learning strategies independent of institution type or class size, and after controlling for individual student characteristics. In addition, we find that the positive effects of interactive learning strategies apply equally to men and women, across ethnicities, for students with all levels of prior mathematical preparation and physical science course experience, independent of GPA, and regardless of primary language. These results powerfully illustrate that all categories of students can benefit from the effective implementation of interactive learning strategies. This material is based upon work supported by the National Science Foundation under Award No. 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars (CATS) Program, and Award No. 0847170, a PAARE grant funding the California-Arizona Minority Partnership for Astronomy Research and Education (CAMPARE).

A feminist action research team, which consisted of a science educator, an English-language learner (ELL) educator, a first-year science teacher, and a graduate assistant, set a goal to work together to explore the process a beginning teacher goes through to establish a classroom conducive to the needs of middle-level ELL learners. The guiding questions of the study were answered by gathering a wealth of data over the course of 5 months and taken from the classroom, planning sessions, and researchers and students. These data were collected by observations, semistructured interviews, and written document reviews. The progressive analysis ultimately revealed that: (a) successful strategies a beginning teacher must utilize for teaching middle-level ELL children in a mainstream classroom involve complex structural considerations that are not part of the teacher's preparation; (b) learning increases for all children, but there are differences in learning achievement between ELL and non-ELL children; and (c) student and peer feedback proved to be an effective means of enhancing the growth of a beginning teacher seeking to increase her skills in teaching ELL learners. The experiences and findings from this project have implications for teacher preparation programs committed to preparing educators to teach science to all children.

This study examined the direct and indirect effects between training in the Responsive Classroom® (RC) approach, teachers' uptake of RC practices, and teacher-student interaction quality, using a structural equation modeling framework. A total of 24 schools were randomly assigned to experimental or control conditions. Third- and fourth-grade teachers in treatment schools (n=132) received training in the RC approach, whereas teachers in control schools (n=107) continued "business as usual." Observers rated teachers' fidelity of implementation (FOI) of RC practices 5 times throughout the year using the Classroom Practices Observation Measure. In addition, teachers completed self-report measures of FOI, the Classroom Practices Teacher Survey and Classroom Practices Frequency Survey, at the end of the school year. Teacher-student interactions were rated during classroom observations using the Classroom Assessment Scoring System. Controlling for teachers' grade level and teacher-student interaction quality at pretest, RC training was expected to predict posttest teacher-student interaction quality directly and indirectly through FOI. Results supported only a significant indirect effect, β=0.85, p=.002. Specifically, RC teachers had higher levels of FOI of RC practices, β=1.62, pteacher-student interaction quality, β=0.52, p=.001, R2=.32. Discussion highlights factors contributing to variability in FOI and school administrators roles in supporting FOI. Copyright © 2013 Society for the Study of School Psychology.

The teacher's role has often been described as one of "orchestration", and this musical analogy is a powerful one in characterising the manipulation of features in the classroom setting in order to generate activity or "performance" which leads to learning. However, a classical view of orchestration would fail to recognise the extent to which…

School-based social and emotional learning (SEL) programs are presented to educators with little understanding of the program components that have the greatest leverage for improving targeted outcomes. Conducted in the context of a randomized controlled trial, the present study used variation in treatment teachers' (N = 143) implementation of four core components of the Responsive Classroom approach to examine relations between each component and the quality of teachers' emotional, organizational, and instructional interactions in third, fourth, and fifth grade classrooms (controlling for pre-intervention interaction quality and other covariates). We also examined the extent to which these relations varied as a function of teachers' baseline levels of interaction quality. Indices of teachers' implementation of Morning Meeting, Rule Creation, Interactive Modeling, and Academic Choice were derived from a combination of teacher-reported surveys and classroom observations. Ratings of teacher-student classroom interactions were aggregated across five observations conducted throughout the school year. Structural path models indicated that teachers' use of Morning Meeting and Academic Choice related to higher levels of emotionally supportive interactions; Academic Choice also related to higher levels of instructional interactions. In addition, teachers' baseline interaction quality moderated several associations such that the strongest relations between RC component use and interaction quality emerged for teachers with the lowest baseline interaction quality. Results highlight the value of examining individual program components toward the identification of program active ingredients that can inform intervention optimization and teacher professional development.

The aim of this study was to investigate the interactions between a-tocopherol and chitosan molecules prepared subsequent to preparation of a-tocopherol-loaded chitosan nanoparticles using ultrasonication. Dynamic light scattering (DLS) and scanning electron microscopy (SEM) analyses showed semi spherical particles with an average size of approximately 350 nm. Also from reconstitution test, a-tocopherol was suggested as stabilizing agent during lyophilization/reconstitution process. The zeta potentials of chitosan and a-tocopherol nanoparticles were larger than ±30 mV, representing suitable stability. Data obtained from FTIR showed possibility of chemical interaction between chitosan and a-tocopherol. Furthermore, the results from FTIR, NMR, and XRD spectroscopy confirmed electrostatic interactions between the two molecules. Overall, this procedure could be considered as a facile method to prepare a-tocopherol-loaded nanoparticles.
The nature of interactions that occurs among teacher, students, learning sources, and learning environment creates different settings to enhance learning. Any setting created by a teacher is affected by 3 (three) types of cognitive load: intrinsic cognitive load, extraneous cognitive load, and germane cognitive load. This study is qualitative in nature, aims to analyse the patterns of interaction that are constituted in mathematics instructions by taking into account the cognitive load theory. The subjects of this study are 21 fifth-grade students who learn mathematics in small groups and whole-class interactive lessons. The data were collected through classroom observations which were videotaped, while field notes were also taken. The data analysis revealed that students engaged in productive interaction and inquiry while they were learning mathematics in small groups or in whole class setting, in which there was a different type of cognitive load that dominantly affecting the learning processes at each setting. During learning mathematics in whole class setting, the most frequently found interaction patterns were to discuss and compare solution based on self-developed models, followed by expressing opinions. This is consistent with the principles of mathematics learning, which gives students wide opportunities to construct mathematical knowledge through individual learning, learning in small groups as well as learning in whole class settings. It means that by participating in interactive learning, the students are habitually engaged in productive interactions and high level of mathematical thinking.

This article investigated to what extent age, use of a cochlear implant, parental hearing status, and use of sign in the home determine language of instruction for profoundly deaf children. Categorical data from 8,325 profoundly deaf students from the 2008 Annual Survey of Deaf and Hard-of-Hearing Children and Youth were analyzed using chi-square automated interaction detector, a stepwise analytic procedure that allows the assessment of higher order interactions among categorical variables. Results indicated that all characteristics were significantly related to classroom communication modality. Although younger and older students demonstrated a different distribution of communication modality, for both younger and older students, cochlear implantation had the greatest effect on differentiating students into communication modalities, yielding greater gains in the speech-only category for implanted students. For all subgroups defined by age and implantation status, the use of sign at home further segregated the sample into communication modality subgroups, reducing the likelihood of speech only and increasing the placement of students into signing classroom settings. Implications for future research in the field of deaf education are discussed.

EU-HOU is freely available on the web, and trains european teachers.
Full Text Available This paper focuses on engaging students in engineering education and provides a case study to exemplify one way of doing this proposing wikis as the main technology for delivering the content and collaborative problem solving as the main approach for working in class. In particular, we flipped part of an undergraduate course on Machine Design following specific design principles. The pre-course content was consisted of existing material, videos, texts and appropriate URLs. This was delivered through a wiki on the wikispaces platform. In class students worked individually and in groups on several types of problems, participating also in a peer review activity. We analysed interaction data recorded by the wiki as well as questionnaires exploring students' perspectives on the particular educational experience. Preliminary results of this pilot study provide evidence about the potential of the flipped classroom in activating students and in increasing interaction within the class.

Full Text Available This article examines how a primary teacher establishes links between students' initial contributions on the theme ‘water’ and the elements that will make up the teaching approach of this subject in the science classroom. For this purpose, we examine discursive interactions in the first lessons of a teaching sequence, looking for links between events that are being elicited and developed by the teacher with intense participation of the students. We shall also examine the teaching strategies conducted by the teacher, emphasizing the presence of visual resources in text production activities, understanding them as literacy practices in the context of science lessons. To examine the effectiveness of these strategies and mediational resources, we shall analyze some exemplars of the students' productions (texts and drawings. We will use as criteria of analysis: speech marks of the opening activity and of the preliminary discussions in the texts produced by the pupils; evidence of changes in the pupils’ initial repertoires about the theme; evidence of connections between the “water in our lives” and “water as a science subject”. The context of the research is a third year grade classroom in a public elementary school in Contagem / MG - Brazil.

This dissertation research project presents the results of a longitudinal study that investigates the knowledge, beliefs, and practices of 13 preservice secondary science teachers participating in a science teacher credentialing/Masters program designed to integrate issues of equity and diversity throughout coursework and seminars. Results are presented in the form of three papers: The first paper describes changes in preservice teacher knowledge about contextualization in science instruction, where contextualization is defined as facilitating authentic connections between science learning and relevant personal, social, cultural, ecological, and political contexts of students in diverse secondary classrooms; the second paper relates changes in the self-efficacy and content-specific beliefs about science, science teaching, diversity, and diversity in science instruction; and the final paper communicates the experiences and abilities of four "social justice advocates" learning to contextualize science instruction in underserved secondary placement classrooms. Results indicate that secondary student teachers developed more sophisticated understandings of how to contextualize science instruction with a focus on promoting community engagement and social/environmental activism in underserved classrooms and how to integrate science content and diversity instruction through student-centered inquiry activities. Although most of the science teacher candidates developed more positive beliefs about teaching science in underrepresented classrooms, many teacher candidates still attributed their minority students' underperformance and a (perceived) lack of interest in school to family and cultural values. The "social justice advocates" in this study were able to successfully contextualize science instruction to varying degrees in underserved placement classrooms, though the most significant limitations on their practice were the contextual factors of their student teaching

An interactional ethnographic study informed by a sociocultural perspective was conducted to examine how a professor and students discursively and interactionally shaped the basis for engaging in the work of a community of geologists. Specifically, the study examined the role the Question of the Day, an interactive writing activity in the lecture, in affording students opportunities for learning the literate practices of science and how to incorporate them in thinking critically. A writing-intensive, introductory oceanography course given in the Geological Sciences Department was chosen because the professor designed it to emphasize writing in the discipline and science literacy within a science inquiry framework. The study was conducted in two phases: a pilot in 2002 and the current study in the Spring Quarter of 2003. Grounded in the view that members in a classroom construct a culture, this study explored the daily construction of the literate practices of science and writing. This view of classrooms was informed by four bodies of research: interactional ethnography, sociolinguistics sociology of science and Writing In the Disciplines. Through participant observation, data were collected in the lecture and laboratory settings in the form of field notes, video, interviews, and artifacts to explore issues of science literacy in discourse, social action, and writing. Examination of participation in the Question of the Day interactive writing activity revealed that it played a key role in initiating and supporting a view of science and inquiry. As the activity permitted collaboration, it encouraged students to engage in the social process to critically explore a discourse of science and key practices with and through their writing. In daily interaction, participants were shown to take up social positions as scientist and engage in science inquiry to explore theory, examine data, and articulately reformulate knowledge in making oral and written scientific arguments

There has been a pedagogic shift in higher education from the traditional teacher centered to the student centered approach in teaching, necessitating a change in the role of the teacher from a supplier of information to passive receptive students into a more facilitative role. Active learning activities are based on various learning theories such as self-directed learning, cooperative learning and adult learning. There exist many instructional activities that enhance active and collaborative learning. The aim of this manuscript is to describe two methods of interactive and collaborative learning in the classroom, automated response systems (ARS) and team-based learning (TBL), and to list some of their applications and advantages. The success of these innovative teaching and learning methods at a large scale depends on few elements, probably the most important of which is the support of the higher administration and leadership in addition to the availability of “champions” who are committed to lead the change.

To compare the impact of 2 different teaching and learning methods on student mastery of learning objectives in a pharmacotherapy module in the large classroom setting. Two teaching and learning methods were implemented and compared in a required pharmacotherapy module for 2 years. The first year, multiple interactive mini-cases with inclass individual assessment and an abbreviated lecture were used to teach osteoarthritis; a traditional lecture with 1 inclass case discussion was used to teach gout. In the second year, the same topics were used but the methods were flipped. Student performance on pre/post individual readiness assessment tests (iRATs), case questions, and subsequent examinations were compared each year by the teaching and learning method and then between years by topic for each method. Students also voluntarily completed a 20-item evaluation of the teaching and learning methods. Postpresentation iRATs were significantly higher than prepresentation iRATs for each topic each year with the interactive mini-cases; there was no significant difference in iRATs before and after traditional lecture. For osteoarthritis, postpresentation iRATs after interactive mini-cases in year 1 were significantly higher than postpresentation iRATs after traditional lecture in year 2; the difference in iRATs for gout per learning method was not significant. The difference between examination performance for osteoarthritis and gout was not significant when the teaching and learning methods were compared. On the student evaluations, 2 items were significant both years when answers were compared by teaching and learning method. Each year, students ranked their class participation higher with interactive cases than with traditional lecture, but both years they reported enjoying the traditional lecture format more. Multiple interactive mini-cases with an abbreviated lecture improved immediate mastery of learning objectives compared to a traditional lecture format, regardless of

The aim is to investigate how encounters with peers affect an individual's meaning making in argumentation about socio-scientific issues, and how the individual's meaning making influences the argumentation at the collective level. The analysis is conducted using the analytical method "transactional argumentation analysis" (TAA) which enables in situ studies. TAA combines a transactional perspective on meaning making based on John Dewey's pragmatic philosophy with an argument analysis based on Toulmin's argument pattern. Here TAA is developed further to enable analysis that in detail clarifies the dynamic interplay between the individual and the collective—the intra- and the inter-personal dimensions—and the result of this interplay in terms of meaning making and learning. The empirical material in this study consists of a video-recorded lesson in a Swedish upper secondary school. The results show that the analysed student is influenced by peers when construing arguments, and thereby acts on others' reasoning when making meaning. Further, the results show that most of the additions made by the analysed student are taken further by peers in the subsequent discussion. This study shows how an individual's earlier experiences, knowledge and thinking contribute to the collective meaning making in the classroom.

Full Text Available This study aimed to identify the teaching strategies used in the classroom and concerns of teachers in the implementation of large class policy. This study also looked at the perception of teachers in their interaction with their students as well as the perception of students at their teacher’s interaction with them. The six speech communication lecturers and 716 undergraduate students in the 2nd semester of 2014-2015 were the participants of the study. Researchers asked teacher respondents to fill out several questionnaires to identify large class-teaching strategies, gauge teacher-student interaction in large classes and determine personal concerns. One-on-one interview with the teacher respondents was also done to validate the results obtained from surveys. Moreover, they also asked students to fill out the Questionnaire on Teacher Interaction (QTI to determine their perception of teacher’s interaction in the classroom. The teachers revealed their various large class teaching strategies, the most common of which is the discussion type. Teachers’ perceived classroom interaction with their students were in agreement with that of their students giving higher scores in the types depicting positive interpersonal behavior like leadership and helpfulness and lower scores in the types depicting negative behavior such as dissatisfaction and admonition. Based from the one-on-one interviews, teacher respondents felt lesser interaction with students in the large lecture class compared to the previous small classroom set-up. Results from teachers’ stages of concern profile showed that they were unconcerned on the implementation of large class policy. Some expressed their strong opposition on the policy and had other educational changes in mind that competed for their attention at the time of the study. There were also issues on credit loading and collaboration with recitation teachers raised during interviews.

Interactional competence, or knowing and using the appropriate skills for interaction in various communication situations within a given speech community and culture is important in the field of business and professional communication , . Similar to many developing countries in the world, Malaysia is a growing economy and undergraduates will have to acquire appropriate communication skills. In this study, two aspects of the interactional communicative competence were investigated, that is the linguistic and paralinguistic behaviors in small group communication as well as conflict management in small group communication. Two groups of student participants were given a problem-solving task based on a letter of complaint. The two groups of students were video recorded during class hours for 40 minutes. The videos and transcription of the group discussions were analyzed to examine the use of language and interaction in small groups. The analysis, findings and interpretations were verified with three lecturers in the field of communication. The results showed that students were able to accomplish the given task using verbal and nonverbal communication. However, participation was unevenly distributed with two students talking for less than a minute. Negotiation was based more on alternative views and consensus was easily achieved. In concluding, suggestions are given on ways to improve English language communication.

Full Text Available Alongside the rise of educational technology, many teachers have been taking gradual but innovative steps to redesign their teaching methods. For example, in flipped learning or a flipped classroom, students watch instructional videos outside the classroom and do assignments or engage in activities inside the classroom. Language teachers are one group of educators exploring the flipped classroom. In foreign language classes, such an approach may offer great benefits for both the teachers and students since classroom time can be applied to more interactive tasks. By extending classroom hours in this way, language teachers can focus on successfully addressing all subjects in the curriculum. The aim of this study is (a to gain insights into the perceptions of prospective English language teachers at a state university in Turkey on flipped classrooms and (b to introduce the implementation of a flipped classroom into an English language class. A total of 47 prospective English teachers participated in the study. Qualitative research design was used and data were collected via an open-ended question. Findings of the study indicated that pre-service English teachers had positive perceptions towards the use of the flipped classroom as an integral part of face-to-face courses. It can be concluded that flipped classroom was beneficial in terms of 4 categories based on the content analysis of the responses: learning at one’s own pace, advance student preparation, overcoming the limitations of class time, increasing the participation in the classroom. The study also provides recommendations towards LMS integration into courses in other English language teaching departments and for implementing flipped classrooms in language teaching.
This project aims to provide students with disabilities the same in class learning experience through virtual reality technology, 360-degree video capture, and the use of Arduino units. These technologies will be combined to facilitate communication between teachers in physical classrooms with students in virtual classrooms. The goal is to provide a person who is affected by a disability (which makes it hard to be in a traditional classroom) the same benefits of a safe and interactive learnin...

When attending for impending visual stimuli, cognitive systems prepare to identify relevant information while ignoring irrelevant, potentially distracting input. Recent work (Marini et al., 2013) showed that a supramodal distracter-filtering mechanism is invoked in blocked designs involving expectation of possible distracter stimuli, although this entails a cost ( distraction-filtering cost ) on speeded performance when distracters are expected but not presented. Here we used an arrow-flanker task to study whether an analogous cost, potentially reflecting the recruitment of a specific distraction-filtering mechanism, occurs dynamically when potential distraction is cued trial-to-trial ( cued distracter-expectation cost ). In order to promote the maximal utilization of cue information by participants, in some experimental conditions the cue also signaled the possibility of earning a monetary reward for fast and accurate performance. This design also allowed us to investigate the interplay between anticipation for distracters and anticipation of reward, which is known to engender attentional preparation. Only in reward contexts did participants show a cued distracter-expectation cost, which was larger with higher reward prospect and when anticipation for both distracters and reward were manipulated trial-to-trial. Thus, these results indicate that reward prospect interacts with the distracter expectation during trial-by-trial preparatory processes for potential distraction. These findings highlight how reward guides cue-driven attentional preparation.

Research shows that female and male students in undergraduate computer science programs view computer culture differently. Female students are interested more in the use of computers than in doing programming, whereas male students see computer science mainly as a programming activity. The overall purpose of our research was not to find new definitions for computer science culture but to see how male and female students see themselves involved in computer science practices, how they see computer science as a successful career, and what they like and dislike about current computer science practices. The study took place in a mid-sized university in Ontario. Sixteen students and two instructors were interviewed to get their views. We found that male and female views are different on computer use, programming, and the pattern of student interactions. Female and male students did not have any major issues in using computers. In computing programming, female students were not so involved in computing activities whereas male students were heavily involved. As for the opinions about successful computer science professionals, both female and male students emphasized hard working, detailed oriented approaches, and enjoying playing with computers. The myth of the geek as a typical profile of successful computer science students was not found to be true.

The purpose of this study was to investigate the attitudes of Saudi Arabian secondary preservice science teachers (SPSTs) toward a variety of science teaching practices. An ultimate, essential goal of this study was to use generated information and findings to improve the current secondary science education programs in Saudi Arabia and to develop better science teacher practices. The selected practices were posted by the National Research Council in 1999. These indicated that students learn science best through understanding of science rather than memorization of scientific facts and concepts, building new knowledge and understanding on what is already known and believed, formulating new knowledge by modifying and refining current concepts and by adding new concepts to what is already known, taking care of their own learning, social learning environments and interactions, and application of knowledge to novel situations. The study's sample consisted of all (147) SPSTs enrolled in the spring semester of 2003 in four Teachers' Colleges: Riyadh, Makkah, Taif, and Dammam. All participants were performing student teaching in secondary schools. This study used quantitative and qualitative data collection methods. Only three SPSTs were purposefully selected from each college for seven semi-structured interview questions, lasting an hour per interview. They were asked to complete a 58-item questionnaire survey and respond to four open-ended survey questions. To assess their attitudes toward the above science teaching practices, data was analyzed using the Rasch analysis model, other parametric tests (e.g., a one-way analysis of variance (ANOVA) and independent-samples t-test), and non-parametric tests (e.g., a chi-square of independent test). Furthermore, qualitative procedures were also used to assess SPSTs' views of some specific aspects about science teaching and the current secondary science education programs in Saudi Arabia. This was achieved through a careful

Many anticancer drugs have the capability to form stable complex with metal ions. Based on such property, a simple method to combine these drugs with transferrin, through the interaction between drug and Fe ion of transferrin, to improve their anticancer activity, is proposed. To demonstrate this technique, the complex of photosensitive anticancer drug hypocrellin A and transferrin was prepared by such facile method. The results indicated that the complex of hypocrellin A and transferrin can stabilize in aqueous solution. In vitro studies have demonstrated the superior cancer cell uptake ability of hypocrellin A–transferrin complex to the free hypocrellin A. Significant damage to such drug-impregnated tumor cells was observed upon irradiation and the cancer cells killing ability of hypocrellin A–transferrin was stronger than the free hypocrellin A within a certain range of concentrations. The above results demonstrated the validity and potential of our proposed strategy to prepare the drug delivery system of this type of anti-cancer drugs and transferrin

This study of the Field Trip Specialist Program (FTS) described how a professional development plan fostered change in the traditional roles of third and fourth grade teachers. Teachers that volunteered were prepared to become interpretive guides for their class on environmental field trips, integrate their basic subject areas lessons into an environmental science context, and develop their self-perception as professional educators. This qualitative study made use of quantitative data and drew on information collected over four years from surveys, interviews, classroom observations, field trip and workshop observations, focus groups, journals and assessments performed in Florida. The FTS Program attracted teachers who thought it was important for all students to understand environmental issues, and these teachers believed in integrated instruction. These beliefs were inconsistent with many aspects of school culture. FTS invited the participation of these teachers and encouraged them to take control of the program by serving as instructors and program developers. Teachers described themselves as prepared to deliver the FTS Program with a high level of motivation and relevance. They also credited the program as beneficial in preparation for the Florida Comprehensive Assessment Tests (FCAT). Teachers reported that their responsibility as field trip leaders was the primary factor motivating them to provide conscientious presentation of pre- and post-field trip lessons and thorough integration of environmental topics in basic subject area instruction. Despite the impact of the field trip leadership factor, I could not find another program in the State of Florida that required teachers to lead their own field trips. Other influential factors specific to this program were: Voluntary participation, on-site field instruction, peer instructors and program developers, high quality and task specific materials, and pre- and post-assessments for students. Factors were identified

In recent decades, the interactive whiteboard (IWB) has become a relatively common educational tool in Western schools. The IWB is essentially a large touch screen, that enables the user to interact with digital content in ways that are not possible with an ordinary computer-projector-canvas setup. However, the unique possibilities of IWBs are rarely leveraged to enhance teaching and learning beyond the primary school level. This is particularly noticeable in high school physics. We describe how a high school physics teacher learned to use an IWB in a new way, how she planned and implemented a lesson on the topic of orbital motion of planets, and what tensions arose in the process. We used an ethnographic approach to account for the teacher's and involved students' perspectives throughout the process of teacher preparation, lesson planning, and the implementation of the lesson. To interpret the data, we used the conceptual framework of activity theory. We found that an entrenched culture of traditional white/blackboard use in physics instruction interferes with more technologically innovative and more student-centered instructional approaches that leverage the IWB's unique instructional potential. Furthermore, we found that the teacher's confidence in the mastery of the IWB plays a crucial role in the teacher's willingness to transfer agency within the lesson to the students.

Full Text Available Flavobacterium heparinum is a soil bacterium that produces several mucopolysaccharidases such as heparinase, heparitinases I and II, and chondroitinases AC, B, C and ABC. The purpose of the present study was to optimize the preparation of F. heparinum chondroitinases, which are very useful tools for the identification and structural characterization of chondroitin and dermatan sulfates. We observed that during the routine procedure for cell disruption (ultrasound, 100 kHz, 5 min some of the chondroitinase B activity was lost. Using milder conditions (2 min, most of the chondroitinase B and AC protein was solubilized and the enzyme activities were preserved. Tryptic soy broth without glucose was the best culture medium both for bacterial growth and enzyme induction. Chondroitinases AC and B were separated from each other and also from glucuronidases and sulfatases by hydrophobic interaction chromatography on HP Phenyl-Sepharose. A rapid method for screening of the column fractions was also developed based on the metachromatic shift of the color of dimethylmethylene blue.

Use of a biharmonic laser pumping for preparation of pure and entangled multiexciton states in dimers and tetramers of resonantly interacting fluorescent particles is analysed. Special emphasis is given to the preparation of all possible pure exciton states and their maximally entangled Bell states. The general results are illustrated using as an example the pair and quartet centres of neodymium ions in calcium fluoride (M- and N-centres), where all necessary experimental information concerning the interactions and decoherence is available, and experimental preparation of Bell vacuum-single exciton and vacuum-biexciton states has been recently demonstrated. These results can be easily rescaled for the cases of quantum dots and dye molecules. Numerical results are compared with the analytical results obtained for a particular case of the biharmonic excitation of dimers. Excellent agreement between these approaches is demonstrated

Economics is often taught at a level of abstraction that can hinder some students from gaining basic intuition. However, lecture and textbook presentations can be complemented with classroom exercises in which students make decisions and interact. The approach can increase interest in and decrease skepticism about economic theory.

The objective of this work was the preparation of modified clays with benzethonium or cetylpyridinium to obtain organophilic silicates with good stability and evaluate the possible use of them for the preparation of nanocomposites of poly(vinyl chloride) (PVC). The reactions of modification of clays and the PVC were prepared by solution intercalation. The new clays were evaluated by X-ray diffraction (XRD) and Low field nuclear magnetic resonance (NMR). The reactions of clays with PVC were assessed by Low-field NMR, through the determination of proton spin lattice relaxation time. The stability of new organophilic clays and their reactions with PVC were evaluated by thermogravimetric analysis (TGA). High stability was observed for organophilic clays prepared. The degradation of PVC materials obtained with the organophilic clay began at temperatures above 200 deg C. If it is considered that the temperatures normally used in the processing of PVC are between 140 deg C to 180 deg C, the observed results may indicate the possibility of the use of clays for preparation of nanomaterials with PVC.

A glucan preparation obtained from the mycelial walls of the fungus Phytophthora megasperma f.sp. glycinea and known as an elicitor of phytoalexins in soybean was shown to be a very efficient inducer of resistance against viruses in tobacco. The glucan preparation protected against mechanically transmitted viral infections on the upper and lower leaf surfaces. Whether the glucan preparation was applied by injection, inoculation, or spraying, it protected the plants if applied before, at the same time as, or not later than 8 hours after virus inoculation. At concentrations ranging from 0.1 to 10 micrograms per milliliter, the glucan preparation induced protection ranging from 50 to 100% against both symptom production (necrotic local lesions, necrotic rings, or systemic mosaic) and virus accumulation in all Nicotiana-virus combinations examined. However, no significant protection against some of the same viruses was observed in bean or turnip. The host plants successfully protected included N. tabacum (9 different cultivars), N. sylvestris, N. glutinosa, and N. clevelandii. The viruses belonged to several taxonomic groups including tobacco mosaic virus, alfalfa mosaic virus, and tomato black ring virus. The glucan preparation did not act directly on the virus and did not interfere with virus disassembly; rather, it appeared to induce changes in the host plant that prevented infections from being initiated or recently established infections from enlarging. The induced resistance does not depend on induction of pathogenesis-related proteins, the phenylpropanoid pathway, lignin-like substances, or callose-like materials. We believe the induced resistance results from a mechanism that has yet to be described.

Interfacial interaction is one of the key factors to improve comprehensive properties of polymer/inorganic filler nanocomposites. In this work, a new interfacial interaction called electron transferring interaction is reported in the nitrile-butadiene rubber/halloysite nanotubes (NBR/HNTs) nanocomposites. The X-ray photoelectron spectroscopy (XPS) and in-situ controlling temperature Fourier transform infrared spectroscopy (FTIR) have confirmed that electrons of electron-rich -CN groups in NBR can transfer to the electron-deficiency aluminum atoms of HNTs, which packs a part of NBR molecules onto the surface of HNTs to form bound rubber and stabilize the homogeneous dispersion of HNTs with few agglomeration as revealed by scanning electron microscope (SEM) and dynamic mechanical analysis (DMA) performances, even at high HNTs addition, resulting in high light transmittance. The tensile strength of NBR/30wt%HNTs nanocomposites is about 291% higher than pure NBR, without sacrificing the elongation at break.

The world is changing significantly, and it is becoming increasingly globalised. This means that countries, businesses, and professionals must think and act globally to be successful. Many individuals, however, are not prepared with the global competency skills needed to communicate and perform effectively in a globalised system. To address this need, higher education institutions are looking for ways to instil these skills in their students. This paper explains one promising approach using current learning principles: transnational interactive online environments in engineering education. In 2011, the TU Dortmund and the University of Virginia initiated a collaboration in which engineering students from both universities took part in one online synchronous course and worked together on global topics. This paper describes how the course was designed and discusses specific research results regarding how interactive online role-playing simulations support students in gaining the global competency skills required to actively participate in today's international workforce.

This article addresses and investigates the dual incorporation of daunorubicin (DR) and 6-mercaptopurine (6-MP) in liposomes for better chemotherapy. These drugs are potential candidates for interaction due to the quinone (H acceptor) and hydroxyl (H donor) groups on DR and 6-MP, respectively. Interactions between the two drugs in solution were monitored by UV/Vis and fluorescence spectroscopy. Interaction between the two drugs inside the liposomes was evaluated by HPLC (for 6-MP) and by fluorescence spectroscopy (for daunorubicin) after phospholipase-mediated liposome lysis. Our results provide evidence for the lack of interaction between the two drugs in solution and in liposomes. The entrapment efficiencies of 6-MP in the neutral Phosphatidyl choline (PC):Cholesterol (Chol):: 2:1 and anionic PC:Chol:Cardiolipin (CL) :: 4:5:1 single and double drug liposomes were found to be 0.4% and 1.5% (on average), respectively. The entrapment efficiencies of DR in the neutral and anionic double drug liposomes were found to be 55% and 31%, respectively. The corresponding entrapment of daunorubicin in the single drug liposomes was found to be 62% on average. Our thin layer chromatography (TLC) and transmission electron microscopy (TEM) results suggest stability of lipid and liposomes, thus pointing plausible existence of double drug liposomes. Cytotoxicity experiments were performed by using both single drug and double drug liposomes. By comparing the results of phase contrast and fluorescence microscopy, it was observed that the double drug liposomes were internalized in the jurkat and Hut78 (highly resistant cell line) leukemia cells as viewed by the fluorescence of daunorubicin. The cytotoxicity was dose dependent and had shown a synergistic effect when double drug liposome was used.
Our ability to engineer quantum states of light and matter has significantly advanced over the past two decades, resulting in the production of both Gaussian and non-Gaussian optical states. The resulting tailored quantum states enable quantum technologies such as quantum optical communication, quantum sensing as well as quantum photonic computation. The strong nonlinear light-atom interaction is the key to deterministic quantum state preparation and quantum photonic processing. One route to enhancing the usually weak nonlinear light-atom interactions is to approach the regime of cavity quantum electrodynamics (cQED) interaction by means of high finesse optical resonators. I present results from the MIT experiment of large conditional cross-phase modulation between a signal photon, stored inside an atomic quantum memory, and a control photon that traverses a high-finesse optical cavity containing the atomic memory. I also present a scheme to probabilistically change the amplitude and phase of a signal photon qubit to, in principle, arbitrary values by postselection on a control photon that has interacted with that state. Notably, small changes of the control photon polarization measurement basis by few degrees can substantially change the amplitude and phase of the signal state. Finally, I present our ongoing effort at Purdue to realize similar peculiar quantum phenomena at the single photon level on chip scale photonic systems.

The aim of this study was to describe the interaction pattern formed between dentin and resin on cavities prepared with an erbium laser (Er:YAG). The morphological aspect of the irradiated dentin after acid etching was also observed. Ten dentin disks were obtained from fresh extracted third molars. Each disk received two cavities, one prepared with a conventional high-speed drill, while the other cavity was obtained by the use of an Er:YAG laser (KaVo KEY Laser, KaVo Co.). The laser treatment was performed with 250 mJ/pulse, 4 Hz, non contact mode, focused beam, and a fine water mist was used. Five disks were prepared for morphological analysis of the acid etched dentin. The other five disks had their cavities restored with Single Bond (3M) followed by Z100 resin (3M). The specimens were observed under scanning electron microscopy after dentin-resin interface demineralization and deproteinization. It was observed that the morphological characteristics of the acid-etched irradiated dentin were not favorable to the diffusion of monomers through the collagen network. The dentin resin interfacial aspect of irradiated dentin, after acid etching, showed thin tags and scarce hybridization zones, which agreed with the morphology of the irradiated and acid-etched dentin substrate observed.

The aim of this study was to identify factors associated with the results of smoking cessation attempts. Data were collected in Clermont-Ferrand from a smoking cessation clinic between 1999 and 2009 (1,361 patients). Smoking cessation was considered a success when patients were abstinent 6 months after the beginning of cessation. Multivariate logistic regression was used to investigate the association between abstinence and different factors. The significant factors were a history of depression (ORadjusted = 0.57, p = 0.003), state of depression at the initial consultation (ORa = 0.64, p = 0.005), other psychoactive substances (ORa = 0.52, psuccess was four times higher). A high score in the Richmond test had a greater impact on success with increasing age (significant interaction: p = 0.01). In exclusive smokers, the contemplation level in the Prochaska algorithm was enough to obtain a satisfactory abstinence rate (65.5%) whereas among consumers of other psychoactive substances, it was necessary to reach the preparation level in the Prochaska algorithm to achieve a success rate greater than 50% (significant interaction: p = 0.02). The psychological preparation of the smoker plays a critical role. The management of smoking cessation must be personalized, especially for consumers of other psychoactive substances and/or smokers with a history of depression.

One approach to improve the bioavailability and efficiency of drugs consists of the association of a ligand (i.e. lectins), showing affinity for biological structures located on the mucosa surfaces, to nanoparticulate drug delivery systems. In this context, Ulex europaeus lectin-gliadin nanoparticle conjugates (UE-GNP) were prepared with the aim of evaluating their in vitro bioadhesive properties. The lectin was fixed by a covalent procedure to gliadin nanoparticles by a two-stage carbodiimide method. Typically, the amount of bound lectin was calculated to be approximately 15 microg lectin/mg nanoparticle, which represented a coupling efficiency of approximately 16% of the initial lectin concentration. In addition, the activity of these conjugates was tested with bovine submaxillary gland mucin (BSM) and the level of binding to this mucin was always much greater with UE-GNP than with controls (gliadin nanoparticles). However, the presence of 50 micromol fucose, which is the reported specific sugar for U. europaeus lectin, specifically inhibited the activity of these conjugates and, therefore, the UE-GNP binding to BSM was attenuated by 70%. These results clearly showed that the activity and specificity of U. europaeus lectin was preserved after covalent coupling to these biodegradable carriers.

Our results show that Co addition stabilizes the tricalcium phosphate structure and decreases the amount of BrC phase in the final product. The in vitro interaction of samples with osteosarcoma MG-63 cells proved the cytocompatibility of all compositions in both normoxic and hypoxic conditions. Although the cell viability increased under hypoxia, the change was insignificant compared with normoxic conditions. Our data show that Co addition reduced hypoxia inducible factor-1α and glioma-associated oncogene family zinc finger 2 expression in MG-63, suggesting Co may provide the benefit of reducing the effects of hypoxia on gene expression in the osteosarcoma cell line.

Classroom observation assignments for preservice teachers allow them to observe detailed relationships among classroom space and teacher student interaction. Through structured observation, preservice teachers become aware of classroom interactions in a vivid and instructive manner. (CJ)
This teacher education program will provide a model for recruiting, educating and retaining high ability students to become mathematics and science lead teachers in elementary schools. The quality experiences and support provided these students will help them develop the knowledge and attitudes necessary to provide leadership for elementary mathematics and science programs. Students will have research experiences at the Ames Laboratory, high quality field experiences with nationally recognized mathematics and science teachers in local schools and opportunities to meaningfully connect these two experiences. This program, collaboratively designed and implemented by scientists, teacher educators and classroom teachers, should provide a replicatable model for other teacher education institutions. In addition, materials developed for the project should help other laboratories interface more effectively with K-8 schools and help other teacher education programs incorporate real science and mathematics experience into their curriculum.

Secondary school teachers have quite busy and complex routines in their classrooms. However, present classroom technologies usually require focused attention from teachers while being interacted with, which restricts their use in teachers’ daily routines. Peripheral interaction is a human-computer interaction style that aims to enable interaction to take place both in the center and periphery of users’ attention and naturally shift between the two. We believe that classroom technologies emplo...

We have explored a novel dual-function stationary phase which combines both strong cation exchange (SCX) and hydrophobic interaction chromatography (HIC) characteristics. The novel dual-function stationary phase is based on porous and spherical silica gel functionalized with ligand containing sulfonic and benzyl groups capable of electrostatic and hydrophobic interaction functionalities, which displays HIC character in a high salt concentration, and IEC character in a low salt concentration in mobile phase employed. As a result, it can be employed to separate proteins with SCX and HIC modes, respectively. The resolution and selectivity of the dual-function stationary phase were evaluated under both HIC and SCX modes with standard proteins and can be comparable to that of conventional IEC and HIC columns. More than 96% of mass and bioactivity recoveries of proteins can be achieved in both HIC and SCX modes, respectively. The results indicated that the novel dual-function column could replace two individual SCX and HIC columns for protein separation. Mixed retention mechanism of proteins on this dual-function column based on stoichiometric displacement theory (SDT) in LC was investigated to find the optimal balance of the magnitude of electrostatic and hydrophobic interactions between protein and the ligand on the silica surface in order to obtain high resolution and selectivity for protein separation. In addition, the effects of the hydrophobicity of the ligand of the dual-function packings and pH of the mobile phase used on protein separation were also investigated in detail. The results show that the ligand with suitable hydrophobicity to match the electrostatic interaction is very important to prepare the dual-function stationary phase, and a better resolution and selectivity can be obtained at pH 6.5 in SCX mode. Therefore, the dual-function column can replace two individual SCX and HIC columns for protein separation and be used to set up two-dimensional liquid

The role of classroom learning in medical education is rapidly changing. To promote active learning and reduce student stress, medical schools have adopted policies such as pass/fail curriculums and recorded lectures. These policies along with the rising importance of the USMLE (United States Medical Licensing Examination) exams have made asynchronous learning popular to the detriment of classroom learning. In contrast to this model, modern day business schools employ mandatory large group classes with assigned seating and cold-calling. Despite similar student demographics, medical and business schools have adopted vastly different approaches to the classroom. When examining the classroom dynamic at business schools with mandatory classes, it is evident that there's an abundance of engaging discourse and peer learning objectives that medical schools share. Mandatory classes leverage the network effect just like social media forums such as Facebook and Twitter. That is, the value of a classroom discussion increases when more students are present to participate. At a time when students are savvy consumers of knowledge, the classroom is competing against an explosion of study aids dedicated to USMLE preparation. Certainly, the purpose of medical school is not solely about the efficient transfer of knowledge - but to train authentic, competent, and complete physicians. To accomplish this, we must promote the inimitable and deeply personal interactions amongst faculty and students. When viewed through this lens, mandatory classes might just be a way for medical schools to leverage their competitive advantage in educating the complete physician.

To evaluate the relative acceptability of the flipped classroom approach compared with traditional didactics for in-house teaching in emergency medicine. Our department changed its learning model from a 'standard' lecture-based model to a 'flipped classroom' model. The 'flipped classroom' included provided pre-session learning objectives and resources before each 2 h weekly session. In-session activities emphasised active learning strategies and knowledge application. Feedback was sought from all medical staff regarding the acceptability of the new approach using an online anonymous cross-sectional qualitative survey. Feedback was received from 49/57 (86%) medical staff. Ninety-eight per cent (48/49) of respondents preferred the flipped classroom over the traditional approach. Aspects of the flipped classroom learners liked most included case-based discussion, interaction with peers, application of knowledge, self-directed learning and small-group learning. Barriers to pre-session learning include work commitments, 'life', perceived lack of time, family commitments, exam preparation and high volume of learning materials. Reported motivational factors promoting pre-session learning include formal assessment, participation requirements, more time, less material, more clinical relevance and/or more interesting material. Case studies and 'hands-on' activities were perceived to be the most useful in-session activities. The flipped classroom shows promise as an acceptable approach to in-house emergency medicine teaching. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

To evaluate organic anion transporter-mediated drug-drug interaction (DDI) potential for individual active components of Danshen (Salvia miltiorrhiza) vs. combinations using in vitro and in silico approaches. Inhibition profiles for single Danshen components and combinations were generated in stably-expressing human (h)OAT1 and hOAT3 cells. Plasma concentration-time profiles for compounds were estimated from in vivo human data using an i.v. two-compartment model (with first-order elimination). The cumulative DDI index was proposed as an indicator of DDI potential for combination products. This index was used to evaluate the DDI potential for Danshen injectables from 16 different manufacturers and 14 different lots from a single manufacturer. The cumulative DDI index predicted in vivo inhibition potentials, 82% (hOAT1) and 74% (hOAT3), comparable with those observed in vitro, 72 ± 7% (hOAT1) and 81 ± 10% (hOAT3), for Danshen component combinations. Using simulated unbound Cmax values, a wide range in cumulative DDI index between manufacturers, and between lots, was predicted. Many products exhibited a cumulative DDI index > 1 (50% inhibition). Danshen injectables will likely exhibit strong potential to inhibit hOAT1 and hOAT3 function in vivo. The proposed cumulative DDI index might improve prediction of DDI potential of herbal medicines or pharmaceutical preparations containing multiple components.

In this work, 2-methacryloyloxyethyl phosphorylcholine (MPC) was used as a ligand to prepare a novel mixed-mode chromatography (MMC) stationary phase by the thiol-ene click reaction onto silica (MPC-silica). It was found that this MPC-silica showed the retention characteristics of hydrophilic interaction chromatography (HILIC) and weak cation exchange chromatography (WCX) under suitable mobile phase conditions. In detail, acidic and basic hydrophilic compounds and puerarin from pueraria were separated quickly with HILIC mode. Meanwhile, six standard proteins were allowed to reach baseline separation in WCX mode, and protein separation from egg white was also achieved with this mode. In addition, reduced/denatured lysozyme could be refolded with the MPC-silica column. In the meantime, the MPC-silica has been applied for refolding with simultaneous purification of recombinant human Delta-like1-RGD (rhDll1-RGD) expressed in Escherichia coli. The results show that the mass recovery and purity of rhDll1-RGD could reach 63.4% and 97% by one step, respectively. Furthermore, the reporter assay results demonstrated that refolded with simultaneously purified rhDll1-RGD could efficiently activate the signalling pathway in a dose-dependent manner. In general, this MPC-silica has good resolution and selectivity in the separation of polar compounds and protein samples in different high-performance liquid chromatography (HPLC) modes, and it successfully achieved refolding with simultaneous purification of denatured protein.

The teaching modality of "flipping the classroom" has garnered recent attention in medical education. In this model, the lecture and homework components are reversed. The flipped classroom lends itself to more interaction in "class" and theoretically improved clinical decision-making. Data is lacking for this model for students in emergency medicine clerkships. We trialed the flipped classroom in our fourth-year student clerkship. Our aim was to learn student and faculty facilitator perceptions of the experience, as it has not been done previously in this setting. We evaluated this in two ways: (1) participant perception of the experience and (2) facilitator (EM physician educator) perception of student preparation, participation, and knowledge synthesis. With permission from its creators, we utilized an online video series derived from the Clerkship Directors in Emergency Medicine. Students were provided the link to these 1 week prior to the classroom experience as the "homework." We developed patient cases generated from the videos that we discussed during class in small-group format. Afterward, students were surveyed about the experience using four-point Likert items and free-text comments and also were evaluated by the facilitator on a nine-point scale. Forty-six clerkship students participated. Students deemed the online modules useful at 2.9 (95 % CI 2.7-3.2). Further, they reported the in-class discussion to be of high value at 3.9 (95 % CI 3.8-4.0), much preferred the flipped classroom to traditional lecturing at 3.8 (95 % CI 3.6-3.9), and rated the overall experience highly at 3.8 (95 % CI 3.7-3.9). Based on preparation, participation, and knowledge synthesis, the facilitator judged participants favorably at 7.4 (95 % CI 7.0-7.8). Students commented that the interactivity, discussion, and medical decision-making were advantages of this format. Students found high value in the flipped classroom and prefer it to traditional lecturing, citing

Research suggests that early classroom experiences influence the socialization of aggression. Tracking changes in the aggressive behavior of 4,179 children from kindergarten to second-grade (ages 5-8), this study examined the impact of 2 important features of the classroom context--aggregate peer aggression and climates characterized by supportive teacher-student interactions. The aggregate aggression scores of children assigned to first-grade classrooms predicted the level of classroom aggression (assessed by teacher ratings) and quality of classroom climate (assessed by observers) that emerged by the end of Grade 1. Hierarchical linear model analyses revealed that first-grade classroom aggression and quality of classroom climate made independent contributions to changes in student aggression, as students moved from kindergarten to second grade. Implications for policy and practice are discussed. © 2011 The Authors. Child Development © 2011 Society for Research in Child Development, Inc.

Cochlear and deep brain implants are prominent examples for neuronal prostheses with clinical relevance. Current research focuses on the improvement of the long-term functionality and the size reduction of neural interface electrodes. A promising approach is the application of carbon nanotubes (CNTs), either as pure electrodes but especially as coating material for electrodes. The interaction of CNTs with neuronal cells has shown promising results in various studies, but these appear to depend on the specific type of neurons as well as on the kind of nanotubes. To evaluate a potential application of carbon nanotube coatings for cochlear electrodes, it is necessary to investigate the cytocompatibility of carbon nanotube coatings on platinum for the specific type of neuron in the inner ear, namely spiral ganglion neurons. In this study we have combined the chemical processing of as-delivered CNTs, the fabrication of coatings on platinum, and the characterization of the electrical properties of the coatings as well as a general cytocompatibility testing and the first cell culture investigations of CNTs with spiral ganglion neurons. By applying a modification process to three different as-received CNTs via a reflux treatment with nitric acid, long-term stable aqueous CNT dispersions free of dispersing agents were obtained. These were used to coat platinum substrates by an automated spray-coating process. These coatings enhance the electrical properties of platinum electrodes, decreasing the impedance values and raising the capacitances. Cell culture investigations of the different CNT coatings on platinum with NIH3T3 fibroblasts attest an overall good cytocompatibility of these coatings. For spiral ganglion neurons, this can also be observed but a desired positive effect of the CNTs on the neurons is absent. Furthermore, we found that the well-established DAPI staining assay does not function on the coatings prepared from single-wall nanotubes.

The goal of this study was to explore relations between teacher characteristics (i.e., competence and wellbeing); social classroom relationships (i.e., teacher-child and peer interactions); and children's social, emotional, and behavioral classroom adjustment. These relations were explored at both the individual and classroom levels among 414 children with emotional and behavioral disorders placed in special education. Two models were specified. In the first model, children's classroom adjustment was regressed on social relationships and teacher characteristics. In the second model, reversed links were examined by regressing teacher characteristics on social relationships and children's adjustment. Results of model 1 showed that, at the individual level, better social and emotional adjustment of children was predicted by higher levels of teacher-child closeness and better behavioral adjustment was predicted by both positive teacher-child and peer interactions. At the classroom level, positive social relationships were predicted by higher levels of teacher competence, which in turn were associated with lower classroom levels of social problems. Higher levels of teacher wellbeing were directly associated with classroom adaptive and maladaptive child outcomes. Results of model 2 showed that, at the individual and classroom levels, only the emotional and behavioral problems of children predicted social classroom relationships. At the classroom level, teacher competence was best predicted by positive teacher-child relationships and teacher wellbeing was best predicted by classroom levels of prosocial behavior. We discuss the importance of positive teacher-child and peer interactions for children placed in special education and suggest ways of improving classroom processes by targeting teacher competence.

Grafting computer projected simulations and interactive engagement methods within a traditional classroom setting: The influence on secondary level students' understanding of Newtonian mechanics and on attitudes towards physics
Zoubeir, Wassim Fouad
This research explored the effects of a constructivist approach using computer projected simulations (CPS) and interactive engagement (IE) methods on 12th grade school students. The treatment lasted 18 weeks during the 1999-2000 fall semester and seeked to evaluate three variations in students': (1)conceptual understanding of Newtonian mechanics as measured by the Force Concept Inventory (FCI), (2)modification of their views about science as measured by the Views About Science Survey (VASS), and (3)achievement on traditional examinations, as measured by their end of semester grades. Analysis of Covariance (ANCOVA) was applied to determine the differences between the mean scores of the experimental group students, and students of the control group, who were exposed to traditional teaching methods only. The FCI data analysis showed that, after 18 weeks, conceptual understanding of Newtonian mechanics had markedly improved only in the experimental group (F(1,99) = 44.739, p performance on the VASS instrument for both groups (F(1,99) = .033, p = .856), confirming previous and comparable findings for studies of short implementation period. The lack of statistically significant difference between the control and experimental groups in graded achievement, while controlling for students' previous achievement, was unexpected (F(1,99) = 1.178, p = .280). It is suggested that in this particular setting, the influence of a technical factor may have been overlooked: the monitored and systematic drill exercises using elaborate math formulae to prepare students for traditional math-loaded exams. Still, despite being intentionally deprived of such preparation throughout the study, students of the experimental group did not achieve less than their counterpart, and in addition, they had gained a satisfactory understanding of Newtonian mechanics. This result points unmistakably at a plausible positive correlation between a better grasp of basic concepts in physics in a challenging
Full Text Available Â This paper describes how English as a Foreign Language (EFL teachers can bring reliable, valid, user-friendly assessment into their classrooms, and thus improve the quality of learning that occurs there. Based on the experience of the author as a an EFL teacher and teacher-trainer, it is suggested that the promotion and development of autonomy, intrinsic motivation, and self-esteem that takes place in a Classroom-Based Assessment (CBA environment facilitates an holistic approach to language learning and prepares the students for the high-stakes tests that often determine their motivation for learning English. Rather than relying on the memorization of language code, form, lexis, and prepared answers, students who have learned in a CBA environment are able to self-assess, peer-assess, build portfolios, and edit their own work. Not only does this reduce the assessment burden on the teacher, but it also develops the skills of problem-solving, critical thinking, and summarization in the students, in addition to a heightened awareness of the language-learning process. By learning how to set goals, assess their achievements, and reflect on their future learning needs, students become more efficient language learners. While acknowledging the place of standardized, summative tests in contemporary society, it is suggested that CBA in the EFL classroom can enhance long-term learning and consequently enable and empower students to prepare for their future learning needs.

In the present study, a new coamorphous phase (CAP) of bioactive herbal ingredient curcumin (CUR) with high solubilitythe was screened with pharmaceutically acceptable coformers. Besides, to provide basic information for the best practice of physiological and pharmaceutical preparations of CUR-based CAP, the interaction between CUR-based CAP and bovine serum albumin (BSA) was studied at the molecular level in this paper. CAP of CUR and piperazine with molar ratio of 1:2 was prepared by EtOH-assisted grinding. The as-prepared CAP was characterized by powder X-ray diffraction, modulated temperature differential scanning calorimetry, thermogravimetric analysis, Fourier-transform infrared, and solid-state 13 C nuclear magnetic resonance. The 1:2 CAP stoichioimetry was sustained by C═O···H hydrogen bonds between the N-H group of the piperazine and the C═O group of CUR; piperazine stabilized the diketo structure of CUR in CAP. The dissolution rate of CUR-piperazine CAP in 30% ethanol-water was faster than that of CUR; the t 50 values were 243.1 min for CUR and 4.378 min for CAP. Furthermore, interactions of CUR and CUR-piperazine CAP with BSA were investigated by fluorescence spectroscopy and density functional theory (DFT) calculation. The binding constants (K b ) of CUR and CUR-piperazine CAP with BSA were 10.0 and 9.1 × 10 3 L mol -1 at 298 K, respectively. Moreover, DFT simulation indicated that the interaction energy values of hydrogen-bonded interaction in the tryptophan-CUR and tryptophan-CUR-piperazine complex were -26.1 and -17.9 kJ mol -1 , respectively. In a conclusion, after formation of CUR-piperazine CAP, the interaction forces between CUR and BSA became weaker.

In this study we implemented the "flipped classroom" model to enhance active learning in medical students taking neurosciences module at Aga Khan University, Karachi. Ninety eight undergraduate medical students participated in this study. The study was conducted from January till March 2017. Study material was provided to students in form of video lecture and reading material for the non-face to face sitting, while face to face time was spent on activities such as case solving, group discussions, and quizzes to consolidate learning under the supervision of faculty. To ensure deeper learning, we used pre- and post-class quizzes, work sheets and blog posts for each session. Student feedback was recorded via a likert scale survey. Eighty four percent students gave positive responses towards utility of flipped classroom in terms of being highly interactive, thought provoking and activity lead learning. Seventy five percent of the class completed the pre-session preparation. Students reported that their queries and misconceptions were cleared in a much better way in the face-to-face session as compared to the traditional setting (4.09 ±1.04). Flipped classroom(FCR) teaching and learning pedagogy is an effective way of enhancing student engagement and active learning. Thus, this pedagogy can be used as an effective tool in medical schools.

The quality of staff/child interactions as measured by the Classroom Assessment Scoring System (CLASS) in Early Childhood Education and Care (ECEC) programs is thought to be important for children's outcomes. The CLASS is made of three domains that assess Emotional Support, Classroom Organization and Instructional Support. It is a relatively new measure that is being used increasingly for research, quality monitoring/accountability and other applied purposes. Our objective was to evaluate the association between the CLASS and child outcomes. Searches of Medline, PsycINFO, ERIC, websites of large datasets and reference sections of all retrieved articles were conducted up to July 3, 2015. Studies that measured association between the CLASS and child outcomes for preschool-aged children who attended ECEC programs were included after screening by two independent reviewers. Searches and data extraction were conducted by two independent reviewers. Thirty-five studies were systematically reviewed of which 19 provided data for meta-analyses. Most studies had moderate to high risk of bias. Of the 14 meta-analyses we conducted, associations between Classroom Organization and Pencil Tapping and between Instructional Support and SSRS Social Skills were significant with pooled correlations of .06 and .09 respectively. All associations were in the expected direction. In the systematic review, significant correlations were reported mainly from one large dataset. Substantial heterogeneity in use of the CLASS, its dimensions, child outcomes and statistical measures was identified. Greater consistency in study methodology is urgently needed. Given the multitude of factors that impact child development it is encouraging that our analyses revealed some, although small, associations between the CLASS and children's outcomes.

This dissertation is a linguistic ethnography of a high school Astronomy/Oceanography classroom in southern Arizona, where an exceptionally promising, novice, white science teacher and mostly Mexican-American students confronted issues of identity and difference through interactions both related and unrelated to science learning. Through close analysis of video-recorded, naturally-occurring interaction and rich ethnographic description, the study documents how a teacher and students accomplished everyday classroom life, built caring relationships, and pursued scientific inquiry at a time and in a place where nationally- and locally-circulating discourses about immigration and race infused even routine interactions with tension and uncertainty. In their talk, students appropriated elements of racializing discourses, but also used language creatively to "speak back" to commonsense notions about Mexicanness. Careful examination of science-related interactions reveals the participants' negotiation of multiple, intersecting forms of citizenship (i.e., cultural and scientific citizenship) in the classroom, through multidirectional processes of language socialization in which students and the teacher regularly exchanged expert and novice roles. This study offers insight into the continuing relevance of racial, cultural, and linguistic identity to students' experiences of schooling, and sheds new light on classroom discourse, teacher-student relationships, and dimensions of citizenship in science learning, with important implications for teacher preparation and practice.

The present study emphasizes the influence of non-covalent interactions on the mechanical and thermal properties of the scaffolds of chitosan/collagen origin. Malonic acid (MA), a bifuncitonal diacid was chosen to offer non-covalent cross-linking. Three dimensional scaffolds was prepared using chitosan at 1.0% (w/v) and MA at 0.2% (w/v), similarly collagen 0.5% (w/v) and MA 0.2% (w/v) and characterized. Results on FT-IR, TGA, DSC, SEM and mechanical properties (tensile strength, stiffness, Young's modulus, etc.) assessment demonstrated the existence of non-covalent interaction between MA and chitosan/collagen, which offered flexibility and high strength to the scaffolds suitable for tissue engineering research. Studies using NIH 3T3 fibroblast cells suggested biocompatibility nature of the scaffolds. Docking simulation study further supports the intermolecular hydrogen bonding interactions between MA and chitosan/collagen.

Classroom questioning is a common teaching and learning strategy in postgraduate nurse education. Technologies such as audience response systems (ARS) may offer advantage over traditional approaches to classroom questioning. However, despite being available since the 1960s, ARSs are still considered novel in many postgraduate nurse education classroom settings. This article aims to explicate the attitudes of postgraduate nursing students in an Irish academic teaching hospital towards classroom questioning (CQ) and the use of ARSs as an alternative to traditional CQ techniques. The results of this small-scale study demonstrate that ARSs have a role to play in CQ in the postgraduate setting, being regarded by students as beneficial to learning, psychological safety and classroom interaction.
Full Text Available The knowledge children bring to the classroom or construct in the classroom may find expression in a variety of activities and is often not measurable with the traditional assessment instruments used in science classrooms. Different approaches to assessment are required to accommodate the various ways in which learners construct knowledge in social settings. In our research we attempted to determine the types of outcomes achieved in a Grade 6 classroom where alternative strategies such as interactive assessments were implemented. Analyses of these outcomes show that the learners learned much more than the tests indicate, although what they learnt was not necessarily science. The implications for assessment are clear: strategies that assess knowledge of science concepts, as well as assessment of outcomes other than science outcomes, are required if we wish to gain a holistic understanding of the learning that occurs in science classrooms.

Full Text Available This study uses the submerged arc discharge method (SADM and the concentrated energy of arc to melt silver metal in deionized water (DW so as to prepare metal fluid with nanoparticles and submicron particles. The process is free from any chemical agent; it is rapid and simple, and rapid and mass production is available (0.5 L/min. Aside from the silver nanoparticle (Ag0, silver ions (Ag+ exist in the colloidal Ag prepared by the system. In the preparation of colloidal Ag, polyvinyl alcohol (PVA is used as an additive so that the Ag0/Ag+ concentration, arcing rate, peak, and scanning electron microscopic (SEM images in the cases with and without PVA can be analyzed. The findings show that the Ag0/Ag+ concentration increases with the addition level of PVA, while the nano-Ag and Ag+ electrode arcing rate rises. The UV-Vis absorption peak increases Ag0 absorbance and shifts as the dispersity increases with PVA addition. Lastly, with PVA addition, the proposed method can prepare smaller and more amounts of Ag0 nanoparticles, distributed uniformly. PVA possesses many distinct features such as cladding, dispersion, and stability.

[This paper is part of the Focused Collection on Preparing and Supporting University Physics Educators.] Undergraduate students are increasingly being used to support course transformations that incorporate research-based instructional strategies. While such students are typically selected based on strong content knowledge and possible interest in teaching, they often do not have previous pedagogical training. The current training models make use of real students or classmates role playing as students as the test subjects. We present a new environment for facilitating the practice of physics pedagogy skills, a highly immersive mixed-reality classroom simulator, and assess its effectiveness for undergraduate physics learning assistants (LAs). LAs prepared, taught, and reflected on a lesson about motion graphs for five highly interactive computer generated student avatars in the mixed-reality classroom simulator. To assess the effectiveness of the simulator for this population, we analyzed the pedagogical skills LAs intended to practice and exhibited during their lessons and explored LAs' descriptions of their experiences with the simulator. Our results indicate that the classroom simulator created a safe, effective environment for LAs to practice a variety of skills, such as questioning styles and wait time. Additionally, our analysis revealed areas for improvement in our preparation of LAs and use of the simulator. We conclude with a summary of research questions this environment could facilitate.

The aim was to evaluate possible interaction in solid and liquid state of the drug with formulation excipients consequent to very fast drug release of diclofenac-Eudragit prolonged release microcapsules. The microcapsules were prepared by drug layering on calcium carbonate cores and coated with Eudragit RS 30D and L30D-55 as previously reported. Suspension of the microcapsules was prepared using microcrystalline cellulose/sodium carboxymethyl cellulose (Avicel CL-611) as medium. In vitro dissolution testing of the suspension was done, and, based on the dissolution results, possible interaction between diclofenac and Eudragit and Avicel in the medium was studied. Powder X-ray diffraction (PXRD) and differential scanning calorimetry (DSC) analyses were performed using 1:1 binary, 1:1:1 ternary mixtures and a ratio equivalent to that in the formulation. The mixtures were prepared by mixing the dispersions--Eudragit RS 30D or L30D-55 with the drug or other components, followed by drying at 60 degrees C for 48 h. Dry mixing was done using the powder equivalents of the polymers, Eudragit RS PO and L100-55, Avicel and calcium carbonate. In vitro dissolution of the suspended microcapsules showed a very fast release after 48 h (T50 = microcapsules (T50 = 6 h). DSC curves of the formulation components or microcapsules did not show the characteristic endothermic peak of diclofenac at 287 degrees C. Powder X-ray diffraction of the binary or ternary mixtures of diclofenac and Eudragit polymers indicated reduction, shift or modification of the crystalline peaks of the drug or excipients at 2theta of 12 degrees and 18 degrees , suggestive of interaction. Some changes in drug peak characteristics at 18 degrees and 23 degrees were observed for Avicel/drug mixture, though not significant. The DSC curves of the binary mixture of diclofenac co-dried with liquid forms of Eudragit (i.e. RS 30D or L30D-55) revealed greater interaction compared to the curves of drug and powdered forms of
The flipped classroom is a pedagogical model in which the typical lecture and homework elements of a course are reversed. The following tips outline the steps involved in making a successful transition to a flipped classroom approach. The tips are based on the available literature alongside the author's experience of using the approach in a medical education setting. Flipping a classroom has a number of potential benefits, for example increased educator-student interaction, but must be planned and implemented carefully to support effective learning.

Full Text Available The LHCf experiment is a CERN experiment dedicated to forward physics which is optimized to measure the neutral particle flow at extreme pseudo-rapidity values, ranging from 8.4 up to infinity. LHCf results are extremely important for the calibration of the hadronic interaction models used for the study of the development of atmospheric showers in the Earth atmosphere. Starting from the recent run of proton-Lead nucleus interactions at LHC, the LHCf and ATLAS collaborations have performed a common data taking which allows a combined study of the central and forward regions of the interaction. The latest results of LHCf, the upgrade of the detectors for the next 6.5 TeV + 6.5 TeV proton–proton run and the status of the LHCf-ATLAS common activities are summarized in this paper.
Full Text Available Abstract Carbon nanotubes [CNTs] were synthesized by the catalytic vapor decomposition method. Thereafter, they were functionalized in order to incorporate the oxygen groups (OCNT and subsequently the amine groups (ACNT. All three CNTs (the as-synthesized and functionalized underwent reaction with an iron organometallic complex (FePcS, iron(III phthalocyanine-4,4",4",4""-tetrasulfonic acid, in order to study the nature of the interaction between this complex and the CNTs and the potential formation of nanocomposite materials. Transmission electronic microscopy, N2 adsorption at 77 K, thermogravimetric analysis, temperature-programmed desorption, and X-ray photoelectron spectroscopy were the characterization techniques employed to confirm the successful functionalization of CNTs as well as the type of interaction existing with the FePcS. All results obtained led to the same conclusion: There were no specific chemical interactions between CNTs and the fixed FePcS.

the teacher's mastery of knowledge, his technic-scientifical capability and ability to teach through research, the socio-cultural characteristics and psychological profiles of the social actors involved - teacher and student. With the goal of searching for a better understanding of this universe, this study was developed and aimed at describing the interactions occurring between a teacher and her students in classrooms in which it was proposed to adopt an inclusive classroom. The data were collected in 2 classrooms in a public primary school in the city of Bauru. The data collecting process was carried out by videotaping the classroom allowing the data to be reviewed later. The taping took place during the first semester of the 2001 school year. The analysis of the data was based on a previously developed system of categories, and the data were dealt quantitative and qualitatively. The results showed peculiarities and differences in the interactions of the teacher with her students, due to the presence or absence of disability. The interaction also demonstrated advances in educational practice regarding the teacher´s attention to the student with disability.

With advocates like Sal Khan and Bill Gates, flipped classrooms are attracting an increasing amount of media and research attention.2 We had heard Khan's TED talk and were aware of the concept of inverted pedagogies in general. Yet it really hit home when we accidentally flipped our classroom. Our objective was to better prepare our students for class. We set out to effectively move some of our course content outside of class and decided to tweak the Just-in-Time Teaching approach (JiTT).3 To our surprise, this tweak—which we like to call the flip-JiTT—ended up completely flipping our classroom. What follows is narrative of our experience and a procedure that any teacher can use to extend JiTT to a flipped classroom.
Full Text Available The educational system in Macedonia is directed towards the modern European standards and models of inclusive education. This is done by initiation and implementation of the innovations in the education.The inclusion of the children with impaired hearing is not connected only with their placement in the schools. In an inclusive school, quality education can be assured only in educational surrounding that is friendly towards the children and the learning process, where the difference is accepted and acknowledged as process for enrichment of all the persons involved. The social aspects of the learning process should be accentuated. This includes a dialogue between the teacher and the other teachers, the teacher and head masters of the schools, between the teacher and the children with impaired hearing and a dialogue with the parents. The teachers should take in consideration the children’s needs and interests and they should be able to conduct a flexible management of the classroom.

Persistent developmental stuttering is associated with basal ganglia dysfunction or dopamine dysregulation. Here, we studied whole-brain functional connectivity to test how basal ganglia structures coordinate and reorganize sensorimotor brain networks in stuttering. To this end, adults who stutter and fluent speakers (control participants) performed a response anticipation paradigm in the MRI scanner. The preparation of a manual Go/No-Go response reliably produced activity in the basal ganglia and thalamus and particularly in the substantia nigra. Strikingly, in adults who stutter, substantia nigra activity correlated positively with stuttering severity. Furthermore, functional connectivity analyses yielded altered task-related network formations in adults who stutter compared to fluent speakers. Specifically, in adults who stutter, the globus pallidus and the thalamus showed increased network synchronization with the inferior frontal gyrus. This implies dynamic shifts in the response preparation-related network organization through the basal ganglia in the context of a non-speech motor task in stuttering. Here we discuss current findings in the traditional framework of how D1 and D2 receptor activity shapes focused movement selection, thereby suggesting a disproportional involvement of the direct and the indirect pathway in stuttering.

The flipped classroom approach is an instructional method that has gained momentum in the last years. In a flipped classroom the traditional lecture and homework sessions are inverted. We believe that the flipped classroom, which employs computer-based individual instruction outside the classroom...... presents data from the second year, where we conducted a survey study among students participating in the flipped statistics course. This study consisted of two surveys designed to gather student perceptions on the out-of-classroom preparation material (videos and quizzes) and the flipped classroom...

The colloidal silver nanoparticles were prepared by the γ-irradiation of silver nitrate (AgNO 3 ) in a mixture solution of water and 2-propanol in the presence of poly(vinylpyrrolidone) as a colloidal stabilizer. The Ag colloids obtained by γ-irradiation were characterized by use of XRD and TEM. The surface of the Ag colloids were modified by use of mercaptosuccinic acid (MSA), (D)-cysteine (Cys), and (L)-Cys, respectively. The MSA and (L)-Cys-capped Ag colloids were aggregated because of hydrogen bonding of the carboxylic acid and amino acid group, respectively. From the analysis by CD spectroscopy, it was shown that chiral-enhanced phenomena were obtained in (L)- and (D)-Cys-capped Ag colloids
Anhydrous Keggin-type phosphorus heteropolyacids were deposited on partially dehydroxylated silica by using the surface organometallic chemistry (SOMC) strategy. The resulting solids were characterized by a combination of physicochemical methods including IR, Raman, 1D and 2D 1H, and 31P MAS NMR, electron microscopy experiments and density functional theory (DFT) calculations. It is shown that the main surface species is [ - Si(OH...H+)]2[H+]1[PM 12O403-] where the polyoxometalate is linked to the support by proton interaction with two silanols. Two other minor species (10% each) are formed by coordination of the polyoxometalate to the surface via the interaction between all three protons with three silanol groups or via three covalent bonds formed by dehydroxylation of the above species. Comparison of the reactivity of these solids and of compounds prepared by a classical way shows that the samples prepared by the SOMC approach contain ca. 7 times more acid sites. © 2010 American Chemical Society.
Full Text Available Pre-service teachers need opportunities to apply theory and connect to best practices as they teach in classroom settings be it, whole or small group. For many pre-service teachers often times their experience is limited to simply watching instruction or working with small groups of students (Pryor & Kuhn, 2004. The student teaching experience is a critical component of the teacher preparation program. Through the use of the English Language Learner Classroom Observation Instrument (ELLCOI, and researcher observation the hope is that these will aid in bringing to light the instructional activities used by pre-service teachers during reading instruction with ELLs. This study explores how pre-service bilingual teachers connect theory into practice by examining their instruction in the following categories: Instructional Practices, Interactive Teaching, English-Language Development, and Content Specific to Reading as listed in The English Language Learner Classroom Observation Instrument (ELLCOI developed by Haager, Gersten, Baker, and Graves (2003. To capture these instructional events video tape recordings of eight South Texas pre-service teachers were taken during a reading language arts lesson in order to observe instruction in high need districts’ dual language/bilingual classrooms. Data were compiled to capture the nature and quality of instruction on key essential elements, as well as reading instructional practices specific to the teaching/learning process in the dual language classroom. The findings portray the results of the ELLCOI with bilingual/ESL pre- service teachers and how they make sense of their instructional practices as a means to instruction in one-way dual language public school classrooms.

This study establishes the effects of a flipped classroom model of instruction on academic performance and attitudes of 66 first-year secondary school students towards chemistry. A pre-test and post-test experimental design was employed to assign students randomly into either the experimental or control group. In order to assess the suitability of using flipped model of instruction, students were divided in two groups. For the first group called the experimental group, a "flipped classroom" was used in which the students were given video lessons and reading materials, before the class to be revised at home. On the other hand, the second group followed traditional methodology, and it was used as control. The rate of reaction knowledge test and the chemistry attitude scale were administered. In addition, the researcher documented classroom observations, experiences, thoughts and insights regarding the intervention in a journal on a daily basis in order to enrich the data. Students were interviewed at the end of the research in order to enrich the qualitative data also. Findings from this study reveal that the flipped instruction model facilitates a shift in students' conceptual understanding of the rate of chemical reaction significantly more than the control condition. Positive significant differences were found on all assessments with the flipped class students performing higher on average. Students in the flipped classroom model condition benefited by preparing for the lesson before the classes and had the opportunity to interact with peers and the teacher during the learning processes in the classroom. The findings support the notion that teachers should be trained or retrained on how to incorporate the flipped classroom model into their teaching and learning processes because it encourages students to be directly involved and active in the learning.

Online social networking is an important part in the everyday life of college students. Despite the increasing popularity of online social networking among students and faculty members, its educational benefits are largely untested. This paper presents our experience in using social networking applications and video content distribution websites as a complement of traditional classroom education. In particular, the solution has been based on effective adaptation, extension and integration of Facebook, Twitter, Blogger YouTube and iTunes services for delivering educational material to students on mobile platforms like iPods and 3 rd generation mobile phones. The goals of the proposed educational platform, described in this paper, are to make the learning experience more engaging, to encourage collaborative work and knowledge sharing among students, and to provide an interactive platform for the educators to reach students and deliver lecture material in a totally new way.

Full Text Available Classroom discussion has the potential to enhance the learning environment and encourages students to become active participants in the educational process. Student participation in classroom discussion has been shown to significantly improve the student learning experience. Research suggests that classroom discussion is an effective method for encouraging student classroom participation and for motivating student learning beyond the classroom. Participation in classroom discussion encourages students to become active collaborators in the learning process, while at the same time providing instructors with a practical method of assessing student learning. Classroom discussion is an effective tool for developing higher-level cognitive skills like critical thinking. Despite the potential discussion holds for student learning, many in academia lament the lack of participation in the classroom. The lack of student participation in classroom discussion is not a recent problem; it is one that has frustrated instructors for decades. Instructors report that some of the more current methods for encouraging classroom discussion can be exasperating and at times non-productive. This two-year study of 510 college and university students provides insight into the reasons why some students do not participate in classroom discussion. This study, which also elicited input from sixteen college and university professors and two high school teachers, offers some suggestions for creating and encouraging an environment conducive to student participation in the classroom.

There is no other naturally occurring defense agent against cancer that has a stronger effect than paclitaxel, commonly known under the brand name of Taxol®. The major drawback for the more widespread use of paclitaxel and its precious precursor, 10-deacetylbaccatin III (10-DAB III), is that they require large-scale extraction from different parts of yew trees (Taxus species), cell cultures, taxane-producing endophytic fungi, and Corylus species. In our previous work, a novel online two-dimensional heart-cut liquid chromatography process using hydrophilic interaction/ reversed-phase chromatography was used to introduce a semi-preparative treatment for the separation of polar (10-deacetylbaccatin III) and non-polar (paclitaxel) taxanes from Taxus baccata L. In this work, a combination of the absorbent (Diaion® HP-20) and a silica based solid phase extraction is utilized as a new, efficient, and cost effective method for large-scale production of taxanes. This process avoids the technical problem of two-dimensional preparative liquid chromatography. The first stage of the process involves discarding co-extractive polar compounds including chlorophylls and pigments using a non-polar synthetic hydrophobic absorbent, Diaion® HP-20. Extract was then loaded on to a silica based hydrophilic interaction solid phase extraction (silica 40-60 micron). Taxanes was eluted using a mixture of water and methanol at the optimized ratio of 70:30. Finally, the fraction containing taxanes was applied to semi-preparative reversed phase HPLC. The results revealed that using this procedure, paclitaxel and 10-DAB III could be obtained at 8 and 3 times more, respectively than by the traditional method of extraction. PMID:29552048

There has been increasing awareness of the need for research and theory to take into account the intersection of individual characteristics and environmental contexts when examining predictors of child outcomes. The present longitudinal, multi-informant study examined the cumulative and interacting contributions of child characteristics (language skills, inattention/hyperactivity, and aggression) and preschool and family contextual factors in predicting kindergarten social skills in 389 low-income preschool children. Child characteristics and classroom factors, but not family factors, predicted teacher-rated kindergarten social skills, while child characteristics alone predicted change in teacher-rated social skills from preschool to kindergarten. Child characteristics and family factors, but not classroom factors, predicted parent-rated kindergarten social skills. Family factors alone predicted change in parent-rated social skills from preschool to kindergarten. Individual child characteristics did not interact with family or classroom factors in predicting parent- or teacher-rated social skills, and support was therefore found for an incremental, rather than an interactive, predictive model of social skills. The findings underscore the importance of assessing outcomes in more than one context, and of considering the impact of both individual and environmental contextual factors on children’s developing social skills when designing targeted intervention programs to prepare children for kindergarten.

This exploratory investigation identifies factors that contribute to success of physical therapy services delivered in the context of the daily routines in preschool classroom settings. Ten pediatric physical therapists from rural and urban communities across North Carolina served as informants during telephone interviews. Qualitative analysis of the data led to the identification of six major themes: interactions among classroom personnel, impact of the classroom environment, individual characteristics of the child, logistical considerations, administrative policies and practices, and service delivery options. All 10 informants shared the perception that the cooperation and commitment of the teacher was essential for successful incorporation of therapy activities in classroom routines. Furthermore, the informants agreed that multiple models of service delivery were necessary to meet the individual needs of children. These results lead the authors to question the wisdom of promoting any one service delivery model as "best practice" and suggest guidelines for successful integration of physical therapy in the preschool classroom.

The present study investigates the interaction of aqueous leaf extract of Psidium guajava with muscarinic, serotonergic and adrenergic receptor system using isolated rat ileum, gastric fundus and trachea, respectively. The concentration-dependent contractile response of aqueous leaf extract of Psidium guajava was parallel and rightward of standard agonists, ACh and 5-HT indicating agonistic activity on muscarinic and serotonergic receptor systems. The inhibition of aqueous leaf extract of Psidium guajava mediated contractions in presence of atropine (10(-7) M) and ketanserin (10(-6) M) confirmed the activity. Relaxant effect of PG (0.2 mg/ml) on carbachol induced pre-contracted rat tracheal chain indicated its agonistic action on adrenergic receptor system. Inhibition (P<0.05) of the action in the presence of propranolol (1 ng/ml) confirmed the activity. It may be concluded that PG possesses agonistic action on muscarinic, serotonergic and adrenergic receptor systems.

This study aims to understand interactions in Korean elementary science classrooms, which are heavily influenced by Confucianism. Ethnographic observations of two elementary science teachers' classrooms in Korea are provided. Their classes are fairly traditional teaching, which mean teacher-centered interactions are dominant. To understand the power and approval in science classroom discourse, we have adopted Critical Discourse Analysis (CDA). Based on CDA, form and function analysis was adopted. After the form and function analysis, all episodes were analyzed in terms of social distance. The results showed that both teachers exercised their power while teaching. However, their classes were quite different in terms of getting approval by students. When a teacher got students' approval, he could conduct the science lesson more effectively. This study highlights the importance of getting approval by students in Korean science classrooms.

There are five strategies based on Spencer-Oatey (2008) that the interactants apply in social interactions. The strategies are request, compliments, apologies, gratitude and disagreement. The research is done to see whether the students realize the management of ra...

Because of the low abundance of glycoprotein and glycopeptide in complex biological samples, it is urgent to develop an efficient method for glycopeptide enrichment in comprehensive and in-depth glycoproteomes research. Herein, a novel hydrophilic silica was developed through surface modification with cysteine-click maltose (Cys-Mal@SiO 2 ). The developed hydrophilic silica was packed into a solid phase extraction (SPE) column, and applied to the highly selective enrichment and identification of N -linked glycopeptides. The Cys-Mal@SiO 2 demonstrated better identification capability over Cys@SiO 2 , Mal@SiO 2 and commercial hydrophilic interaction liquid chromatography (HILIC) in glycopeptide enrichment due to the synergistic effect of the two kinds of hydrophilic molecules. In the selective enrichment of tryptic digest from human immunoglobulin G, glycopeptides with higher signal-to-noises were detected by Cys-Mal@SiO 2 . In addition, 1551 unique glycopeptides with 906 N -glycosylation sites from 466 different N -linked glycoproteins were identified from the proteins extracted from mouse liver after the enrichment with Cys-Mal@SiO 2 . In contrast, the numbers of identified glycopeptides, glycoproteins and N -glycosylation sites identified by Cys@SiO 2 were 211, 67, 127 respectively less than by Cys-Mal@SiO 2 , and the corresponding numbers were 289, 76, 193 by Mal@SiO 2 . These results showed that the developed Cys-Mal@SiO 2 is a promising affinity material for N -glycoproteomics research of real complex biological samples.

Full Text Available The importance of listening in language learning can hardly be overestimated. In classrooms, students always do more listening than speaking. Listening competence is universally “larger” than other competence. Listening is not a oneway street. It is not merely the process of a unidirectional receiving of audible symbols one facet – the first step – 0f listening comprehension is the psychomotor process of receiving sound waves through the ear and transmitting nerve impulses to the brain. Every classroom lesson involves some form of assessment, whether it is in the form of informal, unplanned, and intuitive teacher processing and feedback, or in formal, prepared, scored tests.

With advocates like Sal Khan and Bill Gates, flipped classrooms are attracting an increasing amount of media and research attention. We had heard Khan's TED talk and were aware of the concept of inverted pedagogies in general. Yet, it really hit home when we accidentally flipped our classroom. Our objective was to better prepare our students for class. We set out to effectively move some of our course content outside of class and decided to tweak the Just-in-Time-Teaching approach (JiTT).

Full Text Available For making teaching and learning more visible, classroom observation plays a central role. It provides teachers with constructive critical feedback in order to improve their classroom management and instructional techniques. For teachers it is important to observe the interaction between teacher-learner within the classroom because it can determine the learning opportunities that students get. Not only that, classroom observation encourages colleagues to collaborate to improve teacher practice and student learning. Feedback from classroom observations is an effective way for providing teachers with the information they need about their classroom behavior, and it can help them in their continuous professional development (CPD. This paper is based upon a practical approach to professional development among teachers through classroom observation. Since we, as teachers, are not born with innate teaching abilities, in fact, we learn and develop gradually with the help of some practical approaches, and classroom observation is a well-known powerful practical approach in primary and higher education to help teachers improve their teaching quality. This article mainly highlights the importance of classroom observation and its guidelines adapted from Observing Classes-CETaL. Further, it emphasizes the limitations of classroom observation, and suggests the ways to carry it out effectively based upon Observing Classes CETaL Model.
Sample preparation prior to HPLC analysis is certainly one of the most important steps to consider in trace or ultratrace analysis. For many years scientists have tried to simplify the sample preparation process. It is rarely possible to inject a neat liquid sample or a sample where preparation may not be any more complex than dissolution of the sample in a given solvent. The last process alone can remove insoluble materials, which is especially helpful with the samples in complex matrices if other interactions do not affect extraction. Here, it is very likely a large number of components will not dissolve and are, therefore, eliminated by a simple filtration process. In most cases, the process of sample preparation is not as simple as dissolution of the component interest. At times, enrichment is necessary, that is, the component of interest is present in very large volume or mass of material. It needs to be concentrated in some manner so a small volume of the concentrated or enriched sample can be injected into HPLC. 88 refs

Cationic magnetic polymer particles Fe 3 O 4 /poly(styrene-butyl acrylate-[2-(methacryloxy)ethyl]trimethylammonium chloride), a type of potential gene carrier, were prepared by emulsifier-free emulsion polymerization with oleic acid modified magnetite Fe 3 O 4 , styrene, butyl acrylate and [2-(methacryloxy)ethyl]trimethylammonium chloride) (METAC). The morphology of the particles was characterized by transmission electron microscopy and the composites of particles were characterized by FT-IR spectroscopy, X-ray diffraction. These results showed that magnetic particles were well dispersed in polymers with the content of about 15%(wt/wt). The composites exhibited superparamagnetism and possessed a certain level of magnetic response. The interactions between the particles with calf-thymus DNA (ct DNA) were confirmed by zeta potential measurement, UV–vis spectroscopy and fluorescence spectroscopy. The DNA-binding capacity determined by the agarose gel electrophoresis showed good binding capacity of the emulsion to DNA. These results suggested the potential of the cationic magnetic polymer emulsion as gene target delivery carrier. - Highlights: ► A new type of cationic magnetic polymer particles was synthesized by emulsifier-free emulsion polymerization. ► Structural, morphological, and magnetic properties of the composite were evaluated. ► The interaction between cationic magnetic polymer particles with DNA was confirmed by zeta potential measurements. ► UV–vis spectrophotometry, fluorescent spectroscopy and agarose gel electrophoresis. ► This process may have potential applications to gene carrier and DNA separation.

Utilizing the flipped classroom is an opportunity for a more engaged classroom session. This educational approach is theorized to improve learner engagement and retention and allows for more complex learning during class. No studies to date have been conducted in the postgraduate medical education setting investigating the effects of interactive, interpolated questions in preclassroom online video material. We created a flipped classroom for core pediatric emergency medicine (PEM) topics using recorded online video lectures for preclassroom material and interactive simulations for the in-classroom session. Lectures were filmed and edited to include integrated questions on an online platform called Zaption. One-half of the residents viewed the lectures uninterrupted (Group A) and the remainder (Group B) viewed with integrated questions (2-6 per 5-15-min segment). Residents were expected to view the lectures prior to in-class time (total viewing time of approximately 2½ h). The 2½-h in-class session included four simulation and three procedure stations, with six PEM faculty available for higher-level management discussion throughout the stations. Total educational time of home preparation and in-class time was approximately 5 h. Residents performed better on the posttest as compared to the pretest, and their satisfaction was high with this educational innovation. In 2014, performance on the posttest between the two groups was similar. However, in 2015, the group with integrated questions performed better on the posttest. An online format combined with face-to-face interaction is an effective educational model for teaching core PEM topics. Copyright © 2016 Elsevier Inc. All rights reserved.

This presentation describes experiences of using Skype in the classroom to connect learners with scientists and explorers all over the world in order to deepen learners' knowledge and understanding of course material, develop their enquiry skills, and broaden their perspectives on life beyond the classroom walls. In a session organised by the Royal Scottish Geographical Society (RSGS) in partnership with Digital Explorer, twenty-five Perth High School students who were studying coral reefs took part in an exciting live Skype chat with researchers on Australia's Great Barrier Reef. Students spoke to a marine biologist and a geographer who were on-board their research vessel some 15,000km away. They learned about the Catlin Survey's cutting-edge research, which was set up to study conditions on the reef, take 50,000 images, and create a baseline for future comparisons. In addition, the scientists aimed to develop an underwater equivalent of Google Streetview, called Seaview, which will allow people everywhere to engage with this incredible ecosystem. We heard about the divers' encounter with Tiger sharks earlier that same day, and had a tour of the research vessel, as well as asking the experts questions about their research findings and career paths. Feedback from the students was extremely positive, and it was clear that the experience had greatly enhanced their studies. For myself and the other teachers involved, it was an exciting (and surreal!) experience, and helped to update our knowledge of our subjects. Between July and December 2013 I volunteered as Community Manager for Digital Explorer in their partnership with Skype in the classroom. Digital Explorer is an educational social enterprise dedicated to engaging young people in global issues, and preparing them to tackle environmental and technological changes in the 21st century. We offered seventeen lessons as part of Skype in the classroom's Exploring Oceans event in October and November, which aimed to

Objective: In this study we implemented the “flipped classroom” model to enhance active learning in medical students taking neurosciences module at Aga Khan University, Karachi. Methods: Ninety eight undergraduate medical students participated in this study. The study was conducted from January till March 2017. Study material was provided to students in form of video lecture and reading material for the non-face to face sitting, while face to face time was spent on activities such as case solving, group discussions, and quizzes to consolidate learning under the supervision of faculty. To ensure deeper learning, we used pre- and post-class quizzes, work sheets and blog posts for each session. Student feedback was recorded via a likert scale survey. Results: Eighty four percent students gave positive responses towards utility of flipped classroom in terms of being highly interactive, thought provoking and activity lead learning. Seventy five percent of the class completed the pre-session preparation. Students reported that their queries and misconceptions were cleared in a much better way in the face-to-face session as compared to the traditional setting (4.09 ±1.04). Conclusion: Flipped classroom(FCR) teaching and learning pedagogy is an effective way of enhancing student engagement and active learning. Thus, this pedagogy can be used as an effective tool in medical schools. PMID:29492071

Increasing sophistication in molecular-replacement (MR) software and the rapid expansion of the PDB in recent years have allowed the technique to become the dominant method for determining the phases of a target structure in macromolecular X-ray crystallography. In addition, improvements in bioinformatic techniques for finding suitable homologous structures for use as MR search models, combined with developments in refinement and model-building techniques, have pushed the applicability of MR to lower sequence identities and made weak MR solutions more amenable to refinement and improvement. MrBUMP is a CCP4 pipeline which automates all stages of the MR procedure. Its scope covers everything from the sourcing and preparation of suitable search models right through to rebuilding of the positioned search model. Recent improvements to the pipeline include the adoption of more sensitive bioinformatic tools for sourcing search models, enhanced model-preparation techniques including better ensembling of homologues, and the use of phase improvement and model building on the resulting solution. The pipeline has also been deployed as an online service through CCP4 online, which allows its users to exploit large bioinformatic databases and coarse-grained parallelism to speed up the determination of a possible solution. Finally, the molecular-graphics application CCP4mg has been combined with MrBUMP to provide an interactive visual aid to the user during the process of selecting and manipulating search models for use in MR. Here, these developments in MrBUMP are described with a case study to explore how some of the enhancements to the pipeline and to CCP4mg can help to solve a difficult case.

Full Text Available There is no questioning that the way people live, interact, communicate, and conduct business is undergoing a profound, rapid change. This change is often referred to as the “digital revolution,” which is the advancement of technology from analog, electronic and mechanical tools to the digital tools available today. Moreover, technology has begun to change education, affecting how students acquire the skill sets needed to prepare for college and a career and how educators integrate digital technological instructional strategies to teach. Numerous studies have been published discussing the barriers of integrating technology, the estimated amount of investment that is needed in order to fully support educational technology, and, of course, the effectiveness of technology in the classroom. As such, this article presents a critical review of the transitions that technology integration has made over the years; the amount of resources and funding that has been allocated to immerse school with technology; and the conflicting results presented on effectiveness of using is technology in education. Through synthesis of selected themes, we found a plethora of technological instructional strategies being used to integrate technology into K-12 classrooms. Also, though there have been large investments made to integrate technology into K-12 classrooms to equip students with the skills needed to prepare for college and a career, the practical use of this investment has not been impressive. Lastly, several meta-analyses showed promising results of effectiveness of technology in the classroom. However, several inherent methodological and study design issues dampen the amount of variance that technology accounts for.

The focus of this study is to examine to what extent and in what ways science teachers practice assessment during classroom interactions in everyday activities in an upper-secondary school in Sweden. We are science teachers working now with a larger research project on assessment in science education that seeks to examine teachers' assessment practices in the upper-secondary school. Framing questions include: are teachers performing an integrated assessment of students' skills as the national curriculum mandates? If so, what do the instructional discourses look like in those situations and what are students' experiences regarding their agency on learning and assessment? We emphasize the social, cultural and historic character of assessment and sustain a situated character of learning instead of the notion that learning is "stored inside the head". Teacher led lessons in three science classrooms were video-recorded and analyzed by combining ethnographic and discourse methods of analysis. Both methods are appropriate to the theoretical foundation of our approach on learning and can give some answers to questions about how individuals interact socially, how their experience is passed on to next generations through language and how language use may reveal cultural changes in the studied context. Making the study of action in a classroom the focal point of sociocultural analysis supports the examination of assessment processes and identification of the social roles in which teachers and students are immersed. Such an approach requires observations of how teachers act in authentic teaching situations when they interact with their students in classroom making possible to observe negotiation processes, agencies when both teachers and students are involved in every-day activities. Our study showed that teachers mostly ignored students' questions and that students solved their own problems by helping each other. Teachers did not provide opportunities for students to discuss
Stereotype threat research revealed that negative stereotypes can disrupt the performance of persons targeted by such stereotypes. This paper contributes to stereotype threat research by providing evidence that domain identification and the difficulty level of test items moderate stereotype threat effects on female students' maths performance. The study was designed to test theoretical ideas derived from stereotype threat theory and assumptions outlined in the Yerkes-Dodson law proposing a nonlinear relationship between arousal, task difficulty and performance. Participants were 108 high school students attending secondary schools. Participants worked on a test comprising maths problems of different difficulty levels. Half of the participants learned that the test had been shown to produce gender differences (stereotype threat). The other half learned that the test had been shown not to produce gender differences (no threat). The degree to which participants identify with the domain of maths was included as a quasi-experimental factor. Maths-identified female students showed performance decrements under conditions of stereotype threat. Moreover, the stereotype threat manipulation had different effects on low and high domain identifiers' performance depending on test item difficulty. On difficult items, low identifiers showed higher performance under threat (vs. no threat) whereas the reverse was true in high identifiers. This interaction effect did not emerge on easy items. Domain identification and test item difficulty are two important factors that need to be considered in the attempt to understand the impact of stereotype threat on performance.

Viscum coloratum (Komar) Nakai, known as Hujisheng in china, has been widely used as a herb medicine to treat a variety of diseases, including cardiovascular diseases, cancer, hypertension, hepatitis and hemorrhage. The aim was to investigate pharmacokinetic interactions among co-existing ingredients in V. coloratum after intravenous administration of three different preparations (four monomer solutions, the mixture of them and Viscum coloratum extracts) to rats. After protein precipitation pretreatment with plasma samples, high performance liquid chromatographic methods were developed and applied to quantitatively determinate the four components [syringin (Syri), homoeriodictyol-7-O-β-D-glycoside (Hedt-III), homoeriodictyol-7-O-β-D-apiose (1 → 2)-β-D-glycoside (Hedt-II) and homoeriodictyol-7-O-β-D-apiosiyl-(1 → 5)-β-D-apiosyl-(1 → 2)-β-D-glycoside (Hedt-I)]. The pharmacokinetic parameters (Area under the curve [AUC(0-t)], AUC(0-∞), t 1/2) were calculated using DAS 2.1 software (Chinese Pharmacological Society, Shanghai, China) and compared statistically by One-way analysis of variance using SPSS software (18.0, Chicago, IL, USA) with P dialectic view in the research and development processes.

A simple "one-pot" approach for the preparation of a new vinyl-functionalized organic-inorganic hybrid monolithic column is described. In this improved method, the hydrolyzed alkoxysilanes of tetramethoxysilane and triethoxyvinylsilane were used as precursors for the synthesis of a silica-based monolith, while 1-hexadecene and sodium ethylenesulfonate were used as vinyl functional monomers along with azobisisobutyronitrile as an initiator. The effects of reaction temperature, urea content, and composition of organic monomers on the column properties (e.g. morphology, mechanical stability, and chromatographic performance) were investigated. The monolithic column was used for the separation of neutral solutes by reversed-phase pressurized capillary. Furthermore, the monolith can separate various aromatic amines, which indicated its excellent cation-exchange capability and hydrophobic interactions. The baseline separation of the aromatic amines was obtained with a column efficiency of up to 78 000 plates/m. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

A mixed-mode chromatographic stationary phase, C18-DTT (dithiothreitol) silica (SiO2) was prepared through "thiol-ene" click chemistry. The obtained material was characterized by fourier transform infrared spectroscope, nitrogen adsorption analysis and contact angle analysis. Chromatographic performance of the C18-DTT was systemically evaluated by studying the effect of acetonitrile content, pH, buffer concentration of the mobile phase and column temperature. It was demonstrated that the novel stationary phase possessed reversed phase liquid chromatography (RPLC)/hydrophilic interaction liquid chromatography (HILIC) mixed-mode property. The stop-flow test revealed that C18-DTT exhibited excellent compatibility with 100% aqueous mobile phase. Additionally, the stability and column-to-column reproducibility of the C18-DTT material were satisfactory, with relative standard deviations of retention factor of the tested analytes (verapamil, fenbufen, guanine, tetrandrine and nicotinic acid) in the range of 1.82-3.72% and 0.85-1.93%, respectively. Finally, the application of C18-DTT column was demonstrated in the separation of non-steroidal anti-inflammatory drugs, aromatic carboxylic acids, alkaloids, nucleo-analytes and polycyclic aromatic hydrocarbons. It had great resolving power in the analysis of various compounds in HILIC and RPLC chromatographic conditions and was a promising RPLC/HILIC mixed-mode stationary phase.

Full Text Available Zinc phthalocyanine labelled polyethylene glycol was prepared to track and monitor the in vivo fate of polyethylene glycol. The chemical structures were characterized by nuclear magnetic resonance and infrared spectroscopy. Their light stability and fluorescence quantum yield were evaluated by UV-Visible and fluorescence spectroscopy methods. The interaction of zinc phthalocyanine labelled polyethylene glycol with bovine serum albumin was evaluated by fluorescence titration and isothermal titration calorimetry methods. Optical imaging in vivo, organ aggregation as well as distribution of fluorescence experiments for tracking polyethylene glycol were performed with zinc phthalocyanine labelled polyethylene glycol as fluorescent agent. Results show that zinc phthalocyanine labelled polyethylene glycol has good optical stability and high emission ability in the near infrared region. Imaging results demonstrate that zinc phthalocyanine labelled polyethylene glycol can track and monitor the in vivo process by near infrared fluorescence imaging, which implies its potential in biomaterials evaluation in vivo by a real-time noninvasive method.

Guided by the person by environment framework, the primary goal of this study was to determine whether classroom chaos moderated the relation between effortful control and kindergarteners' school adjustment. Classroom observers reported on children's ( N = 301) effortful control in the fall. In the spring, teachers reported on classroom chaos and school adjustment outcomes (teacher-student relationship closeness and conflict, and school liking and avoidance). Cross-level interactions between effortful control and classroom chaos predicting school adjustment outcomes were assessed. A consistent pattern of interactions between effortful control and classroom chaos indicated that the relations between effortful control and the school adjustment outcomes were strongest in high chaos classrooms. Post-hoc analyses indicated that classroom chaos was associated with poor school adjustment when effortful control was low, suggesting that the combination of high chaos and low effortful control was associated with the poorest school outcomes.

This study was conducted during the hematology block on year three students. Five lectures were delivered online only. Asynchronous discussion boards were created where students could interact with colleagues and instructors. A flipped classroom was introduced with application exercises. Summative assessment results were compared with previous year results as a historical control for statistical significance. Student feedback regarding their blended learning experience was collected. A total of 127 responses were obtained. Approximately 22.8% students felt all lectures should be delivered through didactic lecturing, while almost 35% felt that 20% of total lectures should be given online. Students expressed satisfaction with blended learning as a new and effective learning approach. The majority of students reported blended learning was helpful for exam preparation and concept clarification. However, a comparison of grades did not show a statistically significant increase in the academic performance of students taught via the blended learning method. Learning experiences can be enriched by adopting a blended method of instruction at various stages of undergraduate and postgraduate education. Our results suggest that blended learning, a relatively new concept in Saudi Arabia, shows promising results with higher student satisfaction. Flipped classrooms replace passive lecturing with active student-centered learning that enhances critical thinking and application, including information retention.

Full Text Available This paper explores different kinds of interaction observed in South African mathematics classrooms in order to unpack the notion of participation in mathematics learning. It argues that conventional question-and-answer methods do not promote the kind of interaction that the new South African curriculum calls for. It presents more appropriate kinds of interactions, where teachers maintain high task demands, respond to genuine learner questions and support conversations among learners. The paper argues that combinations of different kinds of interaction are most likely to support learner participation and mathematical thinking in classrooms.

The flipped classroom is an instruction method that has gained momentum during the last years due to technological advances allowing the online sharing of teaching material and learning activities. Bishop and Verleger defined the flipped classroom as “...an educational technique that consists...... of two parts: interactive group learning activities inside the classroom, and direct computer-based individual instruction outside the classroom” (Bishop & Verleger, 2013). So far, research on flipped classroom has mostly concentrated on student perceptions, engagement and achievement level, e...... course in order to adjust it to the flipped classroom model. We have also seen that these considerations have forced teachers to also reconsider the learning objectives of specific activities. Another aspect that promoted reflection was the production of video lectures. Finally, teachers reflected...

The Astronomer in the Classroom program provides professional astronomers the opportunity to engage with 3rd-12th grade students across the nation in grade appropriate discussions of their recent research, and provides students with rich STEM content in a personalized forum, bringing greater access to scientific knowledge for underserved populations. 21st Century Learning and Interstellar Studios, the producer of the 400 Years of the Telescope documentary along with their educational partners, will provide the resources necessary to facilitate the Astronomer in the Classroom program, allowing students to interact with astronomers throughout the IYA2009. PROGRAM DESCRIPTION One of hundreds of astronomers will be available to interact with students via live webcast daily during Spring/Fall 2009. The astronomer for the day will conduct three 20-minute discussions (Grades 3-5 /6-8/9-12), beginning with a five-minute PowerPoint on their research or area of interest. The discussion will be followed by a question and answer period. The students will participate in real-time from their school computer(s) with the technology provided by 21st Century Learning. They will see and hear the astronomer on their screen, and pose questions from their keyboard. Teachers will choose from three daily sessions; 11:30 a.m., 12:00 p.m., 12:30 p.m. Eastern Time. This schedule overlaps all US time zones, and marginalizes bandwidth usage, preventing technological barriers to web access. The educational partners and astronomers will post materials online, providing easy access to information that will prepare teachers and students for the chosen discussion. The astronomers, invited to participate from the AAS and IAU, will receive a web cam shipment with instructions, a brief training and conductivity test, and prepaid postage for shipment of the web cam to the next astronomer on the list. The anticipated astronomer time required is 3-hours, not including the time to develop the PowerPoint.

Many classrooms in higher education still rely on a transformative approach to teaching where students attend lectures and earn course grades through examination. In the modern age, traditional lectures are argued by some as obsolete and do not address the learning needs of today’s students. An emerging pedagogical approach is the concept of the flipped classroom. The flipped classroom can simply be described as students viewing asynchronous video lectures on their own and then engaging in active learning during scheduled class times. In this study, we examined the flipped classroom teaching environment on student learning gains in an Introduction to Equine Science course. Students (n = 130) were asked to view 7.5 h of recorded lectures divided into 8 learning modules, take online quizzes to enforce lecture viewing, take 3 in-class exams, and prepare to participate in active learning during scheduled class times. Active learning approaches included individual activities, paired activities, informal small groups, and large group activities. When compared to students in the traditional lecture format in earlier years, students in the flipped format scored higher on all 3 exams (P flipped format students were asked to take the Cornell Critical Thinking Exam (version X). Scores improved from the pretest (50.8 ± 0.57) to the posttest (54.4 ± 0.58; P flipped course, no correlations were found with student performance and interactions with online content. Students were asked in class to evaluate their experiences based on a 5-point Likert scale: 1 (strongly disagree) to 5 (strongly agree). The flipped classroom was ranked as an enjoyable learning experience with a mean of 4.4 ± 0.10, while students responded positively to other pointed questions. In formal course evaluations, flipped format students ranked the following higher (P flipped classroom proved to be a positive learning experience for students.

Research on student-led small-group learning in schools going back nearly four decades has documented many types of student participation that promote learning. Less is known about how the teacher can foster effective groupwork behaviours. This paper reviews research that explores the role of the teacher in promoting learning in small groups. The focus is on how students can learn from their peers during small-group work, how teachers can prepare students for collaborative group work, and the role of teacher discourse and classroom norms in small-group dialogue. Studies selected for review focused on student-led small-group contexts for learning in which students were expected to collaborate, reported data from systematic observations of group work, and linked observational data to teacher practices and student learning outcomes. This review uncovered multiple dimensions of the teacher's role in fostering beneficial group dialogue, including preparing students for collaborative work, forming groups, structuring the group-work task, and influencing student interaction through teachers' discourse with small groups and with the class. Common threads through the research are the importance of students explaining their thinking, and teacher strategies and practices that may promote student elaboration of ideas.

"Flipped Classroom" is one of the most popular teaching models, and has been applied in more and more curriculums. It is totally different from the traditional teaching model. In the "Flipped Classroom" model, the students should watch the teaching video afterschool, and in the classroom only the discussion is proceeded to improve the students' comprehension. In this presentation, "Flipped Classroom" was studied and practiced in opto-electronic technology curriculum; its effect was analyzed by comparing it with the traditional teaching model. Based on extensive and deep investigation, the phylogeny, the characters and the important processes of "Flipped Classroom" are studied. The differences between the "Flipped Classroom" and the traditional teaching model are demonstrated. Then "Flipped Classroom" was practiced in opto-electronic technology curriculum. In order to obtain high effectiveness, a lot of teaching resources were prepared, such as the high-quality teaching video, the animations and the virtual experiments, the questions that the students should finish before and discussed in the class, etc. At last, the teaching effect was evaluated through analyzing the result of the examination and the students' surveys.

Reform efforts in science education have focused on engaging students in authentic scientific practices. For these efforts to succeed, detailed articulations of scientific practice need to be linked to understandings of classroom practice. Here we characterize engagement in practice generally in terms of 3Rs: routines, roles, and responsibilities. We argue that there is a misalignment between the 3Rs of scientific practice and the practices common in classrooms, and that this misalignment poses a considerable obstacle for beginning teachers who attempt to implement reform pedagogy. As part of a secondary methods course, 16 preservice teachers (PSTs) participated in two exemplar activities designed to engage them in scientific practices. The PST performances suggest that at least initially, they did not consider authentic scientific practices appropriate for classroom activities, implying a pedagogical repertoire dominated by the 3Rs of traditional classrooms. PST performances, however, evidenced a shift in the 3Rs from those common in classrooms to those required by these activities, suggesting that their visions for classrooms are malleable and underlining the importance of aligning the 3Rs of scientific and classroom practices during teacher preparation.

Full Text Available The aim of this study is to evaluate teacher behaviour in creating an effective classroom management process with regard to the views of the teachers working in primary and secondary schools. This is a qualitative study in which the case study design was used. The related literature was scanned and 9 open-ended questions were prepared. These questions that based on maximum variation sampling method were posed to 18 teachers. The data were collected by interview forms and were examined by descriptive and content analysis methods. According to the findings obtained, teachers have stated that pre-determination of classroom rules, asking for students' advices, lecturing in a planned manner, planned teaching, various methods, communication skills, time management, being a model and transitions between activities affect the process of classroom management positively; while punishment affects it in a partly positive way and the differences among the discipline perceptions affect the classroom management negatively

The flipped classroom (FC) approach to teaching has been increasingly employed in undergraduate medical education in recent years. In FC applications, students are first exposed to content via online resources. Subsequent face-to-face class time can then be devoted to student-centered activities that promote active learning. Although the FC has been well received by students in other contexts, the perceptions of medical students regarding this innovation are unclear. This review serves as an early exploration into medical student perceptions of benefits and limitations of the FC. Medical students have generally expressed strong appreciation for the pre-class preparation activities (especially when facilitated by concise, readily accessed online tools) as well as for interactive, engaging small group classroom activities. Some students have expressed concerns with the FC and noted that suboptimal student preparation and insufficient direction and structure during active learning sessions may limit the student-centered benefits. Although students generally perceive that FC approaches can improve their learning and knowledge, this has not been conclusively shown via performances on assessment tools, which may be related to caveats with the assessment tools used. In any case, lifelong self-directed learning skills are perceived by medical students to be enhanced by the FC. In conclusion, medical students have generally expressed strong satisfaction with early applications of the FC to undergraduate medical education, and generally prefer this method to lecture-based instruction.
Galileo's contributions are so familiar as to be taken for granted, obscuring the exploratory process by which his discoveries arose. The wonder that Galileo experienced comes alive for undergraduates and teachers that I teach, when they find themselves taking Galileo's role by means of their own explorations. These classroom journeys include: sighting through picture frames to understand perspective, watching the night sky, experimenting with lenses and motion, and responding to Galileo's story. In teaching, I use critical exploration, the research pedagogy developed by Eleanor Duckworth that arose historically from both the clinical interviewing of Jean Piaget and B"arbel Inhelder and the Elementary Science Study of the 1960s. During critical explorations, the teacher supports students' investigations by posing provocative experiences while interactively following students' emergent understandings. In the context of Galileo, students learned to observe carefully, trust their observations, notice things they had never noticed before, and extend their understanding in the midst of pervasive confusion. Personal investment moved students to question assumptions that they had never critically evaluated. By becoming Galileo in today's classroom, we found the ordinary world no less intriguing and unsettling to explore, as the historical world of protagonists in Galileo's Dialogue.

The purpose of this study was to examine the interactive effects that a child's race and the racial composition of a classroom have on a variety of sociometric measures. Sociometric nominations were collected from 872 fifth-grade students (48% male, 48% Black) who were in classrooms that ranged from nearly all Black to nearly all White students. Hierarchical Linear Modeling analyses indicated that the race of the child, the race of the rater, and the classroom race composition each impacted sociometric nominations. Results suggest that schools that are more balanced in the distribution of Black and White students might promote more positive interracial peer relationships. However, opportunities to be highly liked and to be perceived as a leader might be greatest in a school in which the child is in the clear racial majority. © 2013 American Orthopsychiatric Association.

Use of the flipped classroom model is recognized as a popular method of instruction. Effective preclass preparation methods can create more time for instructors to reinforce application, evaluation, and analysis of information using active learning strategies. This quasi-experimental study used a convenience sample of 42 third-year baccalaureate nursing students. Students were randomized into two groups and received either a narrated video (vodcast) or guided readings for the preclass preparation. A quiz was administered to assess preparation prior to class, and students completed a survey following the classroom activities. Students preferred media preparation to guided readings. This preference translated to higher quiz scores. Positive correlations were noted between quiz scores and students' understanding and increased confidence. Students' preference for the vodcast translated to the perception of an increase in confidence and understanding of the material. [J Nurs Educ. 2018;57(3):163-165.].

The RULER Approach to Social and Emotional Learning ("RULER") is designed to improve the quality of classroom interactions through professional development and classroom curricula that infuse emotional literacy instruction into teaching-learning interactions. Its theory of change specifies that RULER first shifts the emotional qualities of classrooms, which are then followed, over time, by improvements in classroom organization and instructional support. A 2-year, cluster randomized controlled trial was conducted to test hypotheses derived from this theory. Sixty-two urban schools either integrated RULER into fifth- and sixth-grade English language arts (ELA) classrooms or served as comparison schools, using their standard ELA curriculum only. Results from multilevel modeling with baseline adjustments and structural equation modeling support RULER's theory of change. Compared to classrooms in comparison schools, classrooms in RULER schools exhibited greater emotional support, better classroom organization, and more instructional support at the end of the second year of program delivery. Improvements in classroom organization and instructional support at the end of Year 2 were partially explained by RULER's impacts on classroom emotional support at the end of Year 1. These findings highlight the important contribution of emotional literacy training and development in creating engaging, empowering, and productive learning environments.
Full Text Available A decrease in student attendance at lectures both nationally and internationally, has prompted educators to re-evaluate their teaching methods and investigate strategies which promote student engagement. The flipped classroom model, grounded in active learning pedagogy, transforms the face-to-face classroom. Students prepare for the flipped classroom in their own time by watching short online videos and completing readings. Face-to-face time is used to apply learning through problem-solving with peers. To improve the engagement and learning outcomes of our second year cohort, lectures were replaced with short online videos and face-to-face time was spent in a flipped classroom. The impact of the flipped classroom was analysed through surveys, attendance records, learning analytics and exam data before and after the implementation of the flipped classroom. Results suggest an increase in student engagement and a positive attitude towards the learning method. However, there were no measurable increases in student learning outcomes.
Full Text Available The inverted classroom is a teaching model, where the students prepare for classroom by watching video lectures. The classroom time is then dedicated to individual practice. We evaluated a mathematics course for electrical engineering students throughout three semesters, where 20% of the topics were taught using the inverted classroom model. The aim was to find out whether the model can help to better address groups with large differences in prior knowledge in mathematics. We report mainly positive feedback from the students, although the opinions vary greatly between the groups. The students appreciate the increased amount of practice in the classroom as well as the possibility to learn at their own pace. Exam performance remained constant in the topics taught using the inverted classroom compared to previous semesters. The exam performance of weaker students also remained constant.

Students' perceptions of classroom goals influence their adoption of personal goals. To assess different forms of classroom goals, recent studies have favoured an overall measure of performance classroom goals, compared to a two-dimensional assessment of performance-approach and performance-avoidance classroom goals (PAVCG). This paper considered the relationship between students' perceptions of classroom goals and their endorsement of personal achievement goals. We proposed that three (instead of only two) classroom goals need to be distinguished. We aimed to provide evidence for this hypothesis by confirmatory factor analysis (CFA) and also by divergent associations between the respective classroom goal and students' personal goal endorsement. A total of 871 (474 female) 10th grade students from several German high schools participated in this study. Students responded to items assessing their perception of mastery, performance-approach, and performance-avoidance goals in the classroom. Additionally, the students reported how much they personally pursue mastery, performance-approach, and performance-avoidance goals. All items referred to German as a specific school subject. RESULTS.A CFA yielded empirical support for the proposed distinction of three (instead of only two) different kinds of classroom goals. Moreover, in hierarchical linear modelling (HLM) analyses all three classroom goals showed unique associations with students' personal goal adoption. The findings emphasized the need to distinguish performance-approach and PAVCG. Furthermore, our results suggest that multiple classroom goals have interactive effects on students' personal achievement strivings. ©2010 The British Psychological Society.

In a flipped classroom approach, learners view educational content prior to class and engage in active learning during didactic sessions. We hypothesized that a flipped classroom improves knowledge acquisition and retention for residents compared to traditional lecture, and that residents prefer this approach. We completed 2 iterations of a study in 2014 and 2015. Institutions were assigned to either flipped classroom or traditional lecture for 4 weekly sessions. The flipped classroom consisted of reviewing a 15-minute video, followed by 45-minute in-class interactive sessions with audience response questions, think-pair-share questions, and case discussions. The traditional lecture approach consisted of a 55-minute lecture given by faculty with 5 minutes for questions. Residents completed 3 knowledge tests (pretest, posttest, and 4-month retention) and surveys of their perceptions of the didactic sessions. A linear mixed model was used to compare the effect of both formats on knowledge acquisition and retention. Of 182 eligible postgraduate year 2 anesthesiology residents, 155 (85%) participated in the entire intervention, and 142 (78%) completed all tests. The flipped classroom approach improved knowledge retention after 4 months (adjusted mean = 6%; P = .014; d = 0.56), and residents preferred the flipped classroom (pre = 46%; post = 82%; P flipped classroom approach to didactic education resulted in a small improvement in knowledge retention and was preferred by anesthesiology residents.
Full Text Available In the 1900’s, distance education attempted to mimic the traditional classroom lecture via the transmission of live or “canned” broadcasts, regardless of the technologies used: satellite, television, film, or radio. These kinds of media predisposed DE to closely adhere to the lecture (sit and absorb model, where content was disseminated in about the same time constraints as a traditional class: taught at scheduled times throughout the week–almost anywhere but not always anytime. Moreover, the modes of presentation in classic DE seemed to hinder the kinds of human interactions normally experienced in the traditional classroom, fostering individualized and isolated learning experiences.Online learning is a hybrid between the traditional classroom and the DE experience. Like the traditional classroom, instruction is teacher-facilitated. The student is enrolled in a conventional course with topic (lecture presentations, reading and homework assignments, classroom discussions, and class projects. Unlike the traditional classroom, courses are web-based and distributed from a distance, using an assortment of synchronous and asynchronous computer technologies and offered anywhere and anytime. In this way, online learning is different from the classic DE model by encouraging decentralized and collaborative learning environments. So that in this presentation will be discuss design principles for online instruction as being a new kind of classroom.

Understanding the social context of classrooms has been a central goal of research focused on the promotion of academic development. Building on the current literature on classroom social settings and guided by a risk and protection framework, this study examines the unique and combined contribution of individual relationships and quality of classroom interactions on behavioral engagement among low-income Latino students in kindergarten to fifth grade (N = 111). Findings indicate that individual relationships with teachers and peers and classroom quality, each independently predicted behavioral engagement. Moreover, high-quality classrooms buffered the negative influence of students' difficulties in individual relationships on behavioral engagement. Findings illuminate the need to consider multiple layers of social classroom relationships and interactions and suggest the potential benefit of targeting classroom quality as a mechanism for improving behavioral engagement in urban elementary schools. © Society for Community Research and Action 2016.

Full Text Available Spoken language is, arguably, the primary means by which teachers teach and students learn. Much of the literature on language in classrooms has focused on discussion that is seen as both a method of instruction and a curricular outcome. While much of the research on discussion has focused on K-12 classrooms, there is also a body of research examining the efficacy of discussion in postsecondary settings. This article provides a review of this literature in order to consider the effect of discussion on student learning in college and university classrooms, the prevalence of discussion in postsecondary settings, and the quality of discussion in these settings. In general, the results of research on the efficacy of discussion in postsecondary settings are mixed. More seriously, researchers have not been explicit about the meaning of discussion and much of what is called discussion in this body of research is merely recitation with minimal levels of student participation. Although the research on discussion in college and university classrooms is inconclusive, some implications can be drawn from this review of the research including the need for future researchers to clearly define what they mean by “discussion.”

Full Text Available Flipped classroom is an approach to learning to write that allows teachers to have one-on-one assistance to help learners in the “during writing” stage in the classroom. Theories are given to the students in a video lectures to watch before class. Because problems in writing mostly occur in “during writing” stage, teacher assistance is crucial. This paper aims to share theoretical review and research findings pertaining to the implementation of flipped classroom model to EFL writing. Research findings show that flipped classroom is able to give greater opportunities for interactive sessions in class which focus on the students’ own concerns, questions, and needs. Therefore, students’ difficulties in “during writing” stage can be minimized

We conducted a study of student performance in and perceptions of a blended classroom delivery of a junior-level fluid mechanics course. In the blended pedagogy, students watch short on-line videos before class, participate in interactive in-class problem solving (in dyads), and complete individualized on-line quizzes weekly. Comparisons are made among four sections of the blended classroom delivery in the period of 2013-2017 to eleven sections delivered in a traditional lecture-style format by the same instructor in 2002-2012. The results reveal dramatic improvement in student engagement, perceptions, and achievement in the blended pedagogy. For instance, the withdrawal/fail/barely-passing (WFD) rate is significantly lower for the blended classroom (8.6% vs. 16.3%; p self-perception of how-much-learned, perception of the value of the course activities, and the overall effectiveness of the course and instructor in the blended classroom.

This study explores elementary teachers' social understandings and employment of directives and politeness while facilitating inquiry science lessons prior and subsequent to their participation in a summer institute in which they were introduced to the scholarly literature on regulative discourse (directives used by teachers to regulate student behavior). A grounded theory analysis of the institute professional development activities revealed that teachers developed an increased awareness of the authoritative functions served by impolite or direct directives (i.e., pragmatic awareness). Furthermore, a comparative microethnographic analysis of participants' inquiry-based classroom practices revealed that after the institute teachers demonstrated an increased ability to share authority with students by strategically making directive choices that were more polite, indirect, inclusive, involvement-focused and creative. Such ability led to a reduced emphasis on teacher regulation of student compliance with classroom behavioral norms and an increased focus on the discursive organization of the inquiry-based science learning/teaching process. Despite teachers' increased pragmatic awareness, teacher-student linguistic relationships did not become entirely symmetrical subsequent to their participation in the summer institute (i.e., teacher authority was not completely relinquished or lost). Based on such findings, it is argued that teachers need to develop higher levels of pragmatic awareness to become effectively prepared to engage in language-mediated teacher-student interaction in the context of inquiry-based science classroom discourse.

Full Text Available The primary recommendation of the 2010 President's Council of Advisors on Science and Technology report on K-12 education was to inspire more students so that they are motivated to study science. Scientists' visits to classrooms are intended to inspire learners and increase their interest in science, but verifications of this impact are largely qualitative. Our primary goal was to evaluate the impact of a longstanding Brain Awareness classroom visit program focused on increasing learners understanding of their own brains. Educational psychologists have established that neuroscience training sessions can improve academic performance and shift attitudes of students from a fixed mindset to a growth mindset. Our secondary goal was to determine whether short interactive Brain Awareness scientist-in-the-classroom sessions could similarly alter learners' perceptions of their own potential to learn. Teacher and student surveys were administered in 4(th-6(th grade classrooms throughout Minnesota either before or after one-hour Brain Awareness sessions that engaged students in activities related to brain function. Teachers rated the Brain Awareness program as very valuable and said that the visits stimulated students' interest in the brain and in science. Student surveys probed general attitudes towards science and their knowledge of neuroscience concepts (particularly the ability of the brain to change. Significant favorable improvements were found on 10 of 18 survey statements. Factor analyses of 4805 responses demonstrated that Brain Awareness presentations increased positive attitudes toward science and improved agreement with statements related to growth mindset. Overall effect sizes were small, consistent with the short length of the presentations. Thus, the impact of Brain Awareness presentations was positive and proportional to the efforts expended, demonstrating that short, scientist-in-the-classroom visits can make a positive contribution to

Full Text Available The success and effectiveness of teaching the LCTL class-room depend on the LCTL research. The study investigated the into-nation contours of seven Indonesian pragmatic particles (kan, ya, kok, lho, dong, deh, and sih to review the functions of the particles. Vide-otaped data of naturally occurring conversations by native speakers of Indonesian were collected. Results indicated the number of into-nation contours for the Indonesian pragmatic particles used by the speakers to organize information (for example, to extend common ground and mark shared knowledge and to convey the speaker’s ex-pression (for example, surprise and emphasis. The particle contour analysis forms a natural link between grammatical and interactional competence and bears an important LCTL pedagogical consequence in terms of both improving teaching materials and bringing the cul-ture closer to the learner. Based on the findings, four strategies in teaching the LCTL classroom are recommended.
Psychology has been an avocation of mine for almost 20 years, and over the past decade I have begun integrating this knowledge into my classroom. My first introduction to psychology was through the Myers-Briggs Type Indicator®. MBTI looks at preferences in how people interact with the world around them. By recognizing how different students receive, process, and communicate information, and how my communication style likely interacts with theirs, I have been able to improve my competence in the classroom. For example, my student evaluations have gone from the low- to mid-5's 13 years ago to mid-6's (out of 7) consistently over the last five years, during which time I have also won four teaching awards and have been nominated for one more at my institution.
Full Text Available This article presents the results obtained during an enquiry based on a questionnaire about the classroom culture. This concept it is understood as a micro-society with its own characteristics derived from the dynamic of socialization and training process. This research aims to investigate certain specific aspects of micro-sociology and emphasis on classroom culture. A relatively new concept is reflected by the normative consensus or the integrated system of values that belongs to the teachers, pupils and school, as a social entity. The integrative ensemble of values, class cohesion degree and training strategies are only a few of the aspects described by 62 pupils aged 17-18 years old, from a very prestigious school in Bucharest. The perception of pupils regarding our concept is the effect of the relational practices and training used constantly by the teachers. Those practices reflect the school’s focus mostly on cognitive performance.

This study investigated the construction of teaching practices that are aimed at including all students in learning the key ideas of science and helping them to develop a voice for participating in the discourses in and outside of the science classroom. Such practices define what in this study is referred to as transformative practice. The study tells the stories of three Black secondary school teachers in South Africa who have worked to construct a transformative practice in their biology and physical science classrooms. Using a life history perspective, the study explored the relationships between teachers' identities and the changes in their classroom practices. Data were collected mainly through periodic interviews with the teachers and observations of their teaching practices over a period of 18 months. An important finding of the study was that the classroom practices of all three teachers were defined by three similar themes of: (1) "covering the content" and preparing their students to succeed in the national examinations, (2) developing deep conceptual understandings of the subject matter, and (3) including all students in their teaching by constructing what other researchers have called a "culturally-relevant" pedagogy. This finding was consistent despite the observed variations of context and personal histories. A major finding of this study on the question of the relationship between identity and teaching practice was that despite the importance of context, subject matter, material and social resources, another category of resources---the "resources of biography"---proved to be crucial for each of the teachers in crafting a transformative pedagogy. These "resources of biography" included such things as the teachers' own experiences of marginalization, the experiences of growing up or living in a particular culture, and the experiences of participating in certain kinds of social, political, religious or professional activities. The study suggests that it

Bringing space exploration recent results and future challenges and opportunities to the knowledge of students has been a preoccupation of educators and space agencies for quite some time. The will to foster student’s interest and reawaken their interest for science topics and in particular research is something occupying the minds of educators in all corners of the globe. But the challenge is growing literally at the speed of light. We are in the age of “Big Data”. Information is available, opportunities to build smart algorithms flourishing. The problem at hand is how we are going to make use of all this possibilities. How can we prepare students to the challenges already upon them? How can we create a scientifically literate and conscious new generation? They are the future of mankind and therefore this is a priority and should quickly be recognized as such. Empowering teachers for this challenge is the key to face the challenges and hold the opportunities. Teachers and students need to learn how to establish fruitful collaboration in the pursuit of meaningful teaching and learning experiences. Teachers need to embrace the opportunities this ICT world is offering and accompany student’s path as tutors and not as explorers themselves. In this training session we intend to explore tools and repositories that bring real cutting edge science to the hands of educators and their students. A full space exploration will be revealed. Planetarium Software - Some tools tailored to prepare an observing session or to explore space mission’s results will be presented in this topic. Participants will also have the opportunity to learn how to plan an observing session.
