Collaboration between researchers and K-12 educators enables an invaluable exchange of teaching philosophies and educational tools. Programs that partner graduate students with K-12 educators serve the dual purpose of training future educators and providing K-12 students with unique opportunities and perspectives. The benefits of this type of partnership include providing students with enhanced educational experiences and positive student-mentor relationships, training STEM graduate students in effective teaching strategies, and providing teachers with a firsthand resource for scientific information and novel educational materials. Many high school students have had little exposure to science beyond the classroom. Frequent interactions with "real-life" scientists can help make science more approachable and is an effective strategy for promoting science as a career. Here I describe my experiences and several lessons designed as a NSK GK-12 fellow. For example, a month-long unit on biogeochemical principles was framed as a crime scene investigation of a fish kill event in Hood Canal, Washington, in which students were given additional pieces of evidence to solve the mystery as they satisfied checkpoints in their understanding of key concepts. The evidence pieces included scientific plots, maps, datasets, and laboratory exercises. A clear benefit of this investigation-style unit is that students were able to learn the material at their individual pace. This structure allowed for a streamlined integration of differentiated materials such as simplified background readings or visual learning aids for struggling students or more detailed news articles and primary literature for more advanced students. Although the NSF GK-12 program has been archived, educators and researchers should pursue new partnerships, leveraging local and state-level STEM outreach programs with the goal of increasing national exposure of the societal benefits of such synergistic activities.

Science Communication versus Science Education: The Graduate Student Scientist as a K-12 Classroom Resource

Science.gov (United States)

Strauss, Jeff; Shope, Richard E., III; Terebey, Susan

2005-01-01

Science literacy is a major goal of science educational reform (NRC, 1996; AAAS, 1998; NCLB Act, 2001). Some believe that teaching science only requires pedagogical content knowledge (PCK). Others believe doing science requires knowledge of the methodologies of scientific inquiry (NRC, 1996). With these two mindsets, the challenge for science educators is to create models that bring the two together. The common ground between those who teach science and those who do science is science communication, an interactive process that galvanizes dialogue among scientists, teachers, and learners in a rich ambience of mutual respect and a common, inclusive language of discourse . The dialogue between science and non-science is reflected in the polarization that separates those who do science and those who teach science, especially as it plays out everyday in the science classroom. You may be thinking, why is this important? It is vital because, although not all science learners become scientists, all K-12 students are expected to acquire science literacy, especially with the implementation of the No Child Left Behind Act of 2001 (NCLB). Students are expected to acquire the ability to follow the discourse of science as well as connect the world of science to the context of their everyday life if they plan on moving to the next grade level, and in some states, to graduate from high school. This paper posits that science communication is highly effective in providing the missing link for K-12 students cognition in science and their attainment of science literacy. This paper will focus on the "Science For Our Schools" (SFOS) model implemented at California State Univetsity, Los Angeles (CSULA) as a project of the National Science Foundation s GK-12 program, (NSF 2001) which has been a huge success in bridging the gap between those who "know" science and those who "teach" science. The SFOS model makes clear the distinctions that identify science, science communication, science

Radencic, S.; McNeal, K. S.; Pierce, D.; Hare, D.

2011-12-01

The Initiating New Science Partnerships in Rural Education (INSPIRE) program at Mississippi State University (MSU), funded by the NSF Graduate STEM Fellows in K-12 Education (GK12) program, focuses on the advancement of Earth and Space science education in K-12 classrooms. INSPIRE is currently in its second year of partnering ten graduate students from the STEM fields of Geosciences, Engineering and Chemistry at MSU with five teachers from local, rural school districts. The five year project serves to increase inquiry and technology experiences in science and math while enhancing graduate student's communication skills as they create interactive lessons linking their STEM research focus to the state and national standards covered in the classrooms. Each graduate student is responsible for the development of two lessons each month of the school year that are then published on the INSPIRE project webpage, www.gk12.msstate.edu, where they are a free resource for any K-12 classroom teacher seeking innovative activities for their classrooms. Many of the participating teachers and graduate students share activities developed with non-participating teachers, expanding INSPIRE's outreach throughout the local community. Numerous challenges were met during the formation of the program as well as throughout the first year in which the project management team worked together to find solutions ensuring that INSPIRE maintained successful partnerships for all involved. Proposed solutions of the following key components were identified by INSPIRE through the development, implementation, and continuous evaluation (internal and external) of the first year of the program as areas that can pose challenges to the construction of strong relationships between STEM research and K-12 classrooms: initializing the partnerships with the K-12 classrooms and STEM graduate fields at the university; maintaining strong partnerships; providing appropriate training and support; developing sound

Involving Practicing Scientists in K-12 Science Teacher Professional Development

Science.gov (United States)

Bertram, K. B.

2011-12-01

The Science Teacher Education Program (STEP) offered a unique framework for creating professional development courses focused on Arctic research from 2006-2009. Under the STEP framework, science, technology, engineering, and math (STEM) training was delivered by teams of practicing Arctic researchers in partnership with master teachers with 20+ years experience teaching STEM content in K-12 classrooms. Courses based on the framework were offered to educators across Alaska. STEP offered in-person summer-intensive institutes and follow-on audio-conferenced field-test courses during the academic year, supplemented by online scientist mentorship for teachers. During STEP courses, teams of scientists offered in-depth STEM content instruction at the graduate level for teachers of all grade levels. STEP graduate-level training culminated in the translation of information and data learned from Arctic scientists into standard-aligned lessons designed for immediate use in K-12 classrooms. This presentation will focus on research that explored the question: To what degree was scientist involvement beneficial to teacher training and to what degree was STEP scientist involvement beneficial to scientist instructors? Data sources reveal consistently high levels of ongoing (4 year) scientist and teacher participation; high STEM content learning outcomes for teachers; high STEM content learning outcomes for students; high ratings of STEP courses by scientists and teachers; and a discussion of the reasons scientists indicate they benefited from STEP involvement. Analyses of open-ended comments by teachers and scientists support and clarify these findings. A grounded theory approach was used to analyze teacher and scientist qualitative feedback. Comments were coded and patterns analyzed in three databases. The vast majority of teacher open-ended comments indicate that STEP involvement improved K-12 STEM classroom instruction, and the vast majority of scientist open-ended comments

Using an Interdisciplinary Approach to Enhance Climate Literacy for K-12 Teachers

Science.gov (United States)

Hanselman, J. A.; Oches, E. A.; Sliko, J.; Wright, L.

2014-12-01

The Next Generation Science Standards (2014) will begin to change how K-12 teachers teach science. Using a scaffolding approach, the standards focus on a depth of knowledge across multiple content areas. This philosophy should encourage inquiry-based teaching methods, provided the teacher has both the knowledge and the confidence to teach the content. Although confidence to teach science is high among secondary science (biology, general science, chemistry) teachers, depth of knowledge may be lacking in certain areas, including climate science. To address this issue, a graduate course in climate science (Massachusetts Colleges Online Course of Distinction award winner) was developed to include inquiry-based instruction, connections to current research, and interdisciplinary approaches to teaching science. With the support of the InTeGrate program (SERC) at Carleton College, a module was developed to utilize cli-fi (climate science present in fictional literature) and related climate data. Graduate students gain an appreciation of scientific communication and an understanding of climate data and its connection to societal issues. In addition, the graduate students also gain the ability to connect interdisciplinary concepts for a deeper understanding of climate science and have the opportunity. By the end of the course, the graduate students use the content learned and the examples of pedagogical tools to develop their own activities in his or her classroom.

Radencic, S.; Dawkins, K. S.; Jackson, B. S.; Walker, R. M.; Schmitz, D.; Pierce, D.; Funderburk, W. K.; McNeal, K.

2014-12-01

Initiating New Science Partnerships in Rural Education (INSPIRE), a NSF Graduate K-12 (GK-12) program at Mississippi State University, pairs STEM graduate students with local K-12 teachers to bring new inquiry and technology experiences to the classroom (www.gk12.msstate.edu). The graduate fellows prepare lessons for the students incorporating different facets of their research. The lessons vary in degree of difficulty according to the content covered in the classroom and the grade level of the students. The focus of each lesson is directed toward the individual research of the STEM graduate student using inquiry based designed activities. Scientific instruments that are used in STEM research (e.g. SkyMaster weather stations, GPS, portable SEM, Inclinometer, Soil Moisture Probe, Google Earth, ArcGIS Explorer) are also utilized by K-12 students in the activities developed by the graduate students. Creativity and problem solving skills are sparked by curiosity which leads to the discovery of new information. The graduate students work to enhance their ability to effectively communicate their research to members of society through the creation of research linked classroom activities, enabling the 7-12th grade students to connect basic processes used in STEM research with the required state and national science standards. The graduate students become respected role models for the high school students because of their STEM knowledge base and their passion for their research. Sharing enthusiasm for their chosen STEM field, as well as the application techniques to discover new ideas, the graduate students stimulate the interests of the classroom students and model authentic science process skills while highlighting the relevance of STEM research to K-12 student lives. The measurement of the student attitudes about science is gathered from pre and post interest surveys for the past four years. This partnership allows students, teachers, graduate students, and the public to

Rogo, Ellen J; Portillo, Karen M

2014-08-01

The literature abounds with research related to building online communities in a single course; however, limited evidence is available on this phenomenon from a program perspective. The intent of this qualitative case study inquiry was to explore student experiences in a graduate dental hygiene program contributing or impeding the development and sustainability of online learning communities. Approval from the IRB was received. A purposive sampling technique was used to recruit participants from a stratification of students and graduates. A total of 17 participants completed semi-structured interviews. Data analysis was completed through 2 rounds - 1 for coding responses and 1 to construct categories of experiences. The participants' collective definition of an online learning community was a complex synergistic network of interconnected people who create positive energy. The findings indicated the development of this network began during the program orientation and was beneficial for building a foundation for the community. Students felt socially connected and supported by the network. Course design was another important category for participation in weekly discussions and group activities. Instructors were viewed as active participants in the community, offering helpful feedback and being a facilitator in discussions. Experiences impeding the development of online learning communities related to the poor performance of peers and instructors. Specific categories of experiences supported and impeded the development of online learning communities related to the program itself, course design, students and faculty. These factors are important to consider in order to maximize student learning potential in this environment. Copyright © 2014 The American Dental Hygienists’ Association.

The average total percentages were calculated for each survey section to compose the final perspective of the included students. The results showed a positive perception toward the use of gamification tools in online learning among graduate students. Students require effort-demanding, challenging, sophisticated learning systems that increase competency, enhance recall memory, concentration, attentiveness, commitment, and social interaction. Limitations of the study are identified, which highlights the need for further research on the subject matter.

Brown, Cynthia J; Wilson, Carol B

2016-12-01

As online education gains momentum, strategies to promote student engagement, develop social presence, and create a virtual community are essential for students' successful learning. A university with a philosophy grounded in caring developed two strategies for the graduate online education setting. These two strategies intentionally promote caring for self and others as a means to foster engagement, social presence, and a vibrant online community. One strategy was online Caring Groups, that is, small groups of four to five nursing students created each semester in one of the students' required courses in the online setting. The second strategy was the creation of two Caring Connections online sites, one for master of science in nursing students and one for doctorate in education nursing students. The sites were developed external to required courses to provide support for the online students throughout the graduate programs. Each site provides an ongoing space for students and faculty to post and discuss inspirational quotes, self-care tips, music, and photographs. The online Caring Groups and Caring Connections sites will be described, including how they were created, how they are used by students, how faculty support students, lessons learned, and how Caring Groups are integrated into the curriculum. © The Author(s) 2016.

Rodak, C. M.; Walsh, M.; Gensic, J.

2011-12-01

Simple water quality test kits were used in a series of K-12 classrooms to demonstrate scientific processes and to motivate learning in K-12 students. While focused on student learning, this project also allowed collection of regional data on groundwater quality (primarily nitrate) in the study area. The project consisted of development and administration of a weeklong groundwater quality unit introduced to K-12 schools in northern Indiana and taught by a graduate student in an engineering discipline. The structure of the week started with an introduction to basic groundwater concepts modified for the specific grade level; for this project the students ranged from grades 4-12. In addition to groundwater basics, the purpose of the collection of the water quality data, as well as relevance to the research of the graduate student, were outlined. The students were then: (i) introduced to two simple water quality testing methods for nitrates, (ii) required to hypothesize as to which method will likely be "better" in application, and (iii) asked to practice using these two methods under laboratory conditions. Following practice, the students were asked to discuss their hypotheses relative to what was observed during the practice focusing on which testing method was more accurate and/or precise. The students were then encouraged to bring water samples from their home water system (many of which are on private wells) to analyze within groups. At the end of the week, the students shared their experience in this educational effort, as well as the resulting nitrate data from numerous groundwater wells (as collected by the students). Following these discussions the data were added to an online database housed on a wiki sponsored by the Notre Dame Extended Research Community (http://wellhead.michianastem.org/home). These data were plotted using the free service MapAList to visually demonstrate to the students the spatial distribution of the data and how their results have

Describing the on-line graduate science student: An examination of learning style, learning strategy, and motivation

Science.gov (United States)

Spevak, Arlene J.

Research in science education has presented investigations and findings related to the significance of particular learning variables. For example, the factors of learning style, learning strategy and motivational orientation have been shown to have considerable impact upon learning in a traditional classroom setting. Although these data have been somewhat generous for the face-to-face learning situation, this does not appear to be the case for distance education, particularly the Internet-based environment. The purpose of this study was to describe the on-line graduate science student, regarding the variables of learning style, learning strategy and motivational orientation. It was believed that by understanding the characteristics of adult science learners and by identifying their learning needs, Web course designers and science educators could create on-line learning programs that best utilized students' strengths in learning science. A case study method using a questionnaire, inventories, telephone interviews and documents was applied to nine graduate science students who participated for ten weeks in an asynchronous, exclusively Internet mediated graduate science course at a large, Northeastern university. Within-case and cross-case analysis indicated that these learners displayed several categories of learning styles as well as learning strategies. The students also demonstrated high levels of both intrinsic and extrinsic motivation, and this, together with varying strategy use, may have compensated for any mismatch between their preferred learning styles and their learning environment. Recommendations include replicating this study in other online graduate science courses, administration of learning style and learning strategy inventories to perspective online graduate science students, incorporation of synchronous communication into on-line science courses, and implementation of appropriate technology that supports visual and kinesthetic learners. Although

Langley, Malinda E; Brown, Sylvia T

2010-01-01

The purpose of this study was to examine the perceptions of graduate nursing students and a small sample of faculty regarding learning outcomes associated with reflective learning journals (RLJ) in online education. Reflective journaling is used extensively in nursing curricula, yet few studies have explored perceptions of learning outcomes with online students, specifically those preparing to become nurse educators.An electronic survey was developed utilizing items associated with four learning outcomes of reflective journaling: professional development, personal growth, empowerment, and facilitation of the learning process. Positive outcomes such as the connection between theory and practice, recognition of strengths and weaknesses, and integration of new ideas and concepts were identified. Obstacles included the amount of time needed for reflection and grading, and the development of trust between students and faculty. The results of this study indicate that graduate students and faculty perceive positive learning outcomes with the use of reflective journals in online education.

K-Nearest Neighbors method is one of methods used for classification which calculate a value to find out the closest in distance. It is used to group a set of data such as students’ graduation status that are got from the amount of course credits taken by them, the grade point average (AVG), and the mini-thesis grade. The study is conducted to know the results of using K-Nearest Neighbors method on the application of determining students’ graduation status, so it can be analyzed from the method used, the data, and the application constructed. The aim of this study is to find out the application results by using K-Nearest Neighbors concept to determine students’ graduation status using the data of STMIK Palangkaraya students. The development of the software used Extreme Programming, since it was appropriate and precise for this study which was to quickly finish the project. The application was created using Microsoft Office Excel 2007 for the training data and Matlab 7 to implement the application. The result of K-Nearest Neighbors method on the application of determining students’ graduation status was 92.5%. It could determine the predicate graduation of 94 data used from the initial data before the processing as many as 136 data which the maximal training data was 50data. The K-Nearest Neighbors method is one of methods used to group a set of data based on the closest value, so that using K-Nearest Neighbors method agreed with this study. The results of K-Nearest Neighbors method on the application of determining students’ graduation status was 92.5% could determine the predicate graduation which is the maximal training data.

deCharon, A.; Repa, J. T.; Companion, C. J.; Taylor, L.

2016-02-01

First piloted in Fall 2014, "Broaden the Impacts of Your Research" is a fully asynchronous (i.e., no live or scheduled sessions) online graduate course. This two-credit offering was designed in response to evaluation data from 73 graduate students who participated in four National Science Foundation-funded workshops (deCharon et al., 2013). As a community of practice, students from various scientific disciplines learn about communication and collaboration skills, practice these skills by developing a portfolio of products, and provide feedback on their classmates' products. The course is organized into four sections during the 14-week semester, each with its own set of objectives including: assessing and reducing jargon; engaging in interdisciplinary collaboration; understanding non-scientist audiences' needs; and deconstructing science and connecting to society. The course's quality was assessed through a review of its design by an external evaluator who also gauged its overall efficacy by comparing students' weekly blog posts with the course's goals and objectives. Effectiveness was also evaluated based on students' data from post-semester surveys. Based on these analyses, it has been determined that the course is most appropriate for students who have conducted their initial research and are preparing to communicate it to others and seek additional funding. It exposes students to communications experts through video guest lectures, and it fosters interdisciplinary online collaboration. Participants benefit from employing a variety of online tools to examine and clarify thinking about their own research. Given that the course is online and 100% asynchronous, it is highly flexible and could potentially serve students worldwide. This presentation will focus on the design of "Broaden the Impacts of Your Research," provide evaluation results from both cohorts (i.e., Fall 2014, Fall 2015), and discuss its transferability to other universities or professional societies.

Bowler, Nicola; Larson, Brian F.; Gray, Joseph N.

2014-02-01

Nondestructive evaluation is a `niche' subject that is not yet offered as an undergraduate or graduate major in the United States. The undergraduate minor in NDE offered within the College of Engineering at Iowa State University (ISU) provides a unique opportunity for undergraduate aspiring engineers to obtain a qualification in the multi-disciplinary subject of NDE. The minor requires 16 credits of course work within which a core course and laboratory in NDE are compulsory. The industrial sponsors of Iowa State's Center for Nondestructive Evaluation, and others, strongly support the NDE minor and actively recruit students from this pool. Since 2007 the program has graduated 10 students per year and enrollment is rising. In 2011, ISU's College of Engineering established an online graduate certificate in NDE, accessible not only to campus-based students but also to practicing engineers via the web. The certificate teaches the fundamentals of three major NDE techniques; eddy-current, ultrasonic and X-ray methods. This paper describes the structure of these programs and plans for development of an online, coursework-only, Master of Engineering in NDE and thesis-based Master of Science degrees in NDE.

Opportunities for learning about animal welfare from online courses to graduate degrees.

Siegford, Janice M; Cottee, Stephanie Yue; Widowski, Tina M

2010-01-01

Knowledge of animal welfare has become essential for veterinarians. However, there is no clear consensus about how to provide veterinarians and students with this critical information. The challenges associated with finding qualified instructors and fitting additional courses into an already full curriculum mean that options for learning about animal welfare beyond the veterinary school classroom must be explored. Online courses can be excellent ways for veterinary students and graduate veterinarians to become familiar with current animal-welfare science, assessment schemes, and regulations while removing geographical barriers and scheduling difficulties. Faculty at Michigan State University have created an online animal-welfare course with lecture material from experts in welfare-related social and scientific fields that provides an overview of the underlying concepts as well as opportunities to practice assessing welfare. However, to develop expertise in animal welfare, veterinarians need more than a single course. Graduate degrees can be a way of obtaining additional knowledge and scientific expertise. Traditional thesis-based graduate programs in animal-welfare science are available in animal-science departments and veterinary colleges throughout North America and offer students in-depth research experience in specific areas or species of interest. Alternatively, the University of Guelph offers a year-long Master of Science degree in which students complete a series of courses with a specialization in animal behavior and welfare along with a focused research project and paper. In summary, a range of options exist that can be tailored to provide graduate veterinarians and veterinary students with credible education regarding animal welfare beyond the veterinary curriculum.

2008-12-01

Many science and research skills are taught by osmosis in graduate programs with the expectation that students will develop good communication skills (speaking, writing, and networking) by observing others, attending meetings, and self reflection. A new National Science Foundation Graduate Teaching Fellows in K- 12 Education (GK-12; http://ehrweb.aaas.org/gk12new/) program at UCLA (SEE-LA; http://measure.igpp.ucla.edu/GK12-SEE-LA/overview.html ) attempts to make the development of good communication skills an explicit part of the graduate program of science and engineering students. SEE-LA places the graduate fellows in two pairs of middle and high schools within Los Angeles to act as scientists-in- residence. They are partnered with two master science teachers and spend two-days per week in the classroom. They are not student teachers, or teacher aides, but scientists who contribute their content expertise, excitement and experience with research, and new ideas for classroom activities and lessons that incorporate inquiry science. During the one-year fellowship, the graduate students also attend a year-long Preparing Future Faculty seminar that discusses many skills needed as they begin their academic or research careers. Students are also required to include a brief (two-page) summary of their research that their middle or high school students would be able to understand as part of their published thesis. Having students actively thinking about and communicating their science to a pre-college audience provides important science communication training and helps contribute to science education. University and local pre- college school partnerships provide an excellent opportunity to support the development of graduate student communication skills while also contributing significantly to the dissemination of sound science to K-12 teachers and students.

Collaborative learning using VoiceThread in an online graduate course

Directory of Open Access Journals (Sweden)

Yu-Hui Ching

2013-09-01

Full Text Available Collaborative learning enables participants in a learning community to externalize and share knowledge, experiences, and practice. However, collaborative learning in an online environment can be challenging due to the lack of face-to face interaction. This current study examined twenty graduate students’ experiences of using VoiceThread for a collaborative activity in an entirely online course to explore students’ perceptions of using multi-modal communication for collaboration and knowledge sharing. The results of this study revealed that graduate students had very positive experiences toward using VoiceThread for collaborative learning. The participants found VoiceThread easy to learn and use, and reported that audio and video interaction on VoiceThread helped connect them with their peers. More than half of the participants interacted with peers using audio, followed by text and then by video. Half of the students felt they were more connected to peers; however, feeling more connected did not result in more participation as most of the students only participated at the level that met the course requirement. Participants identified benefits and drawbacks of using VoiceThread for collaboration as compared to using text-based discussion forums. The most frequently mentioned benefit of using VoiceThread for collaboration exemplifies its multi-modal affordance that enables learners to communicate emotion, personality, and other non-verbal cues conducive to better understanding and interpretation of meanings. About half of the participants indicated that they preferred VoiceThread to text-based discussion forums for collaborative learning activity. Challenges and implications for future research are also discussed.

Mary E. Dykes

2003-06-01

Full Text Available The experiences of an instructor and teaching assistant who employed online communication strategies in a graduate seminar are examined in this paper. This paper expands on the findings reported in an earlier article on virtual learning communities founded on social constructivist pedagogy (Schwier & Balbar, 2002. We examine how the instructors constructed and refined structured discussions of content with synchronous and asynchronous communication at the graduate level. The instructors offer several observations and principles that are organized into categories that illustrate the source, message, channel and receiver in the communication system. The critical reflections of the instructors are compared with data from interviews with students about learning experienced in the online discussions (Dykes, 2003. Findings include the realization that instructors may fundamentally misinterpret or overlook important elements of communication, but that students are robust learners who can transcend the limitations of the medium and the instructor if given the authority in a social constructivist learning environment.

Holding Your Hand From a Distance: Online Mentoring and the Graduate Library and Information Science Student

Directory of Open Access Journals (Sweden)

Elizabeth A. Buchanan, Ph.D.,

2005-07-01

Full Text Available The emergence of online education in colleges and universities brings with it a variety of issues and concerns for the remote student. One such issue is online mentoring. This paper presents a study that examines perceptions of the impact and role of online mentoring by online graduate students in a Master of Library and Information Science program. The guiding research question asked “what impact does online mentoring have on the online student experience?” A survey using open and closed-ended response questions was administered. Findings indicate that the participants see the need for online mentors in at least two forms—peer mentors to assist with the “institutional maze” surrounding distance education programs, and secondly, professional mentors to assist with career planning and development. Institutions should thus consider a two-tiered mentor network to meet the needs of students at various points in their academic lives.

Online education, a form of distance education, provides students with opportunities to engage in lifelong learning without the restrictions of time and space. However, while this approach meets the needs of employed nursing professionals, it poses some challenges for educators. Student retention is one such challenge. Student retention rates serve as measures of program quality and are reported to accrediting bodies. Therefore, it is imperative that administrators and program faculty implement comprehensive programs to ensure student retention. This review of the literature was designed to identify strategies to improve student retention in online graduate nursing education programs. The review includes 23 articles that address models, research, and best practices supported in nursing and higher education. The findings indicate that student retention in online programs is a multidimensional problem requiring a multifaceted approach. Recommendations for facilitating retention in online nursing programs include ensuring social presence and program and course quality, and attentiveness to individual student characteristics.

Full Text Available As the number of online degree programs continues to grow, one of the greatest challenges is developing a sense of community among learners who do not convene at the same time and place. This study examined the sense of community among medical professionals in an online graduate program for healthcare professionals. We took the sample from a fully online program delivered jointly by a state university and a local children's hospital in the Midwest. We administered Rovai's Classroom Community Survey with 11 additional demographic questions. We also utilized online interviews to further explore students’ understanding of sense of community. A bi-factor model was fitted to the online sense of community survey data. Using multivariate analysis of variance (MANOVA and univariate analysis of variance (ANOVA we identified potential group differences. The qualitative data were analyzed thematically in a recursive and iterative process. Study results suggested that a dominant factor existed: sense of community with two sub-domain factors including sense of learning and sense of connectedness. No significant differences in sense of community with regard to gender, native language, or area of medical practice were detected. However, results showed a difference in sense of community between the three courses examined. This study is the first to examine the sense of community among online medical professionals. Since our findings are in contrast to those of previous studies, this opens the door to additional studies around the possible differences between the community characteristics and needs of medical professionals as online students.

Buck, Gayle A.; Leslie-Pelecky, Diandra L.; Lu, Yun; Plano Clark, Vicki L.; Creswell, John W.

2006-10-01

Women continue to be underrepresented in the fields of science, technology, engineering, and mathematics (STEM). One factor contributing to this underrepresentation is the graduate school experience. Graduate programs in STEM fields are constructed around assumptions that ignore the reality of women's lives; however, emerging opportunities may lead to experiences that are more compatible for women. One such opportunity is the Graduate Teaching Fellows in K-12 Education (GK-12) Program, which was introduced by the National Science Foundation in 1999. Although this nontraditional graduate program was not designed explicitly for women, it provided an unprecedented context in which to research how changing some of the basic assumptions upon which a graduate school operates may impact women in science. This exploratory case study examines the self-definition of 8 women graduate students who participated in a GK-12 program at a major research university. The findings from this case study contribute to higher education's understanding of the terrain women graduate students in the STEM areas must navigate as they participate in programs that are thought to be more conducive to their modes of self-definition while they continue to seek to be successful in the historically Eurocentric, masculine STEM fields.

Bopp, Melissa; Hastmann, Tanis J; Norton, Alyssa N

2013-01-01

Walking and biking to work, active commuting (AC) is associated with many health benefits, though rates of AC remain low in the US. K-12 educators represent a significant portion of the workforce, and employee health and associated costs may have significant economic impact. Therefore, the purpose of this study was to examine the current rates of AC and factors associated with AC among K-12 educators. A volunteer sample of K-12 educators (n = 437) was recruited to participate in an online survey. Participants responded about AC patterns and social ecological influences on AC (individual, interpersonal, institutional, community, and environmental factors). t-tests and ANOVAs examined trends in AC, and Pearson correlations examined the relationship between AC and dependent variables. Multiple regression analysis determined the relative influence of individual, interpersonal, institutional, community, and environmental levels on AC. Participants actively commuted 0.51 ± 1.93 times/week. There were several individual, interpersonal, institutional, community, and environmental factors significantly related to AC. The full model explained 60.8% of the variance in AC behavior. This study provides insight on the factors that determine K-12 educators mode of commute and provide some insight for employee wellness among this population.

K-12 Professional Development at the Harvard Forest LTER

Science.gov (United States)

Bennett, K.

2012-12-01

As part of the Long Term Ecological Research (LTER) program, the Harvard Forest in Petersham, Massachusetts seeks to train the next generation of researchers, by involving K-12 grade students and their teachers in hands-on, field-based, ecological research in their own schoolyard and community. Students learn to collect data on important long-term ecological issues and processes. Student data are then shared on the Harvard Forest website. To prepare teachers for project protocols, teachers are given direct access to Harvard ecologists with professional development workshops and on-line resources. With the Harvard Forest Schoolyard LTER program, students can participate in three different research projects focusing on phenology, invasive insects, and vernal pools. Teachers attend the Summer Institute for Teachers to learn project content and methods. They return in fall to participate in one of three levels of data workshops to learn how to input, manage, and analyze project data. In the spring, teachers again meet with the Harvard ecologists about project protocols, and to share, through a series of teacher presentations, the ways these project themes are being integrated into class curricula. These professional development opportunities result in long term collaborative partnerships with local schools and the Harvard Forest LTER. In addition to the LTER Schoolyard Ecology Program, the Harvard Forest has supported a successful Research Experience for Teachers (RET) program for the last six years. Throughout the summer, teachers work on research projects alongside Harvard Forest and affiliated scientists, post-docs, graduate students, and REU's (Research Experience for Undergraduates). The RET program provides teachers with the opportunity to build scientific knowledge, develop an understanding of research methods, and translate their new knowledge and experiences into cutting edge classroom lessons.

Exploring counter-theoretical instances of graduate learners’ self-regulatory processes when using an online repository

Directory of Open Access Journals (Sweden)

Kamran Shaikh

2012-01-01

Full Text Available Academic self-regulation theories have proposed that learning involves a complex set of cognitive and metacognitive mechanisms that are enacted in phases. These phases include task understanding, strategy adoption, monitoring, and reflection. Whereas classical approaches to self-regulation contend that these phases work together to influence academic performance, the empirical research reported herein reveals that, for essay writing in an online learning environment, improved self-regulation is not necessarily associated with improved learning outcomes. We begin by reviewing frameworks for academic self-regulation, specifically in the context of learners’ experiences in online repositories equipped with Topic Maps (ISO 13250 indexes. We then offer explanations for counter-theoretical interactions found between task understanding (a frontline phase of self-regulation and academic performance in 38 graduate learners who used Topic Maps to tackle ill-structured essay tasks. Our investigation sheds light not only on how learners’ perceptions of feedback facilitate task understanding, but also on the complex relationship between task understanding and monitoring proficiencies.

Using Scientific Visualizations to Enhance Scientific Thinking In K-12 Geoscience Education

Science.gov (United States)

Robeck, E.

2016-12-01

The same scientific visualizations, animations, and images that are powerful tools for geoscientists can serve an important role in K-12 geoscience education by encouraging students to communicate in ways that help them develop habits of thought that are similar to those used by scientists. Resources such as those created by NASA's Scientific Visualization Studio (SVS), which are intended to inform researchers and the public about NASA missions, can be used in classrooms to promote thoughtful, engaged learning. Instructional materials that make use of those visualizations have been developed and are being used in K-12 classrooms in ways that demonstrate the vitality of the geosciences. For example, the Center for Geoscience and Society at the American Geosciences Institute (AGI) helped to develop a publication that outlines an inquiry-based approach to introducing students to the interpretation of scientific visualizations, even when they have had little to no prior experience with such media. To facilitate these uses, the SVS team worked with Center staff and others to adapt the visualizations, primarily by removing most of the labels and annotations. Engaging with these visually compelling resources serves as an invitation for students to ask questions, interpret data, draw conclusions, and make use of other processes that are key components of scientific thought. This presentation will share specific resources for K-12 teaching (all of which are available online, from NASA, and/or from AGI), as well as the instructional principles that they incorporate.

Teaching Experiences for Graduate Student Researchers: A Study of the Design and Implementation of Science Courses for Secondary Students

Science.gov (United States)

Collins, Anne Wrigley

Modern science education reform recommends that teachers provide K-12 science students a more complete picture of the scientific enterprise, one that lies beyond content knowledge and centers more on the processes and culture of scientists. In the case of Research Experience for Teachers (RET) programs, the "teacher" becomes "researcher" and it is expected that he/she will draw from the short-term science research experience in his/her classroom, offering students more opportunities to practice science as scientists do. In contrast, this study takes place in a program that allows graduate students, engaged in research full-time, to design and implement a short-duration course for high school students on Saturdays; the "researcher" becomes "teacher" in an informal science program. In this study, I investigated eleven graduate students who taught in the Saturday Science (SS) program. Analyses revealed participants' sophisticated views of the nature of science. Furthermore, participants' ideas about science clearly resonated with the tenets of NOS recommended for K-12 education (McComas et al., 1998). This study also highlighted key factors graduate students considered when designing lessons. Instructors took great care to move away from models of traditional, "lecture"-based, university science teaching. Nonetheless, instruction lacked opportunities for students to engage in scientific inquiry. In instances when instructors included discussions of NOS in SS courses, opportunities for high school students to learn NOS were not explicit enough to align with current science reform recommendations (e.g., AAAS, 2009). Graduate students did, however, offer high school students access to their own science or engineering research communities. These findings have significant implications for K-12 classroom reform. Universities continue to be a valuable resource for K-12 given access to scientists, materials or equipment, and funding. Nonetheless, and as was the case with

Nucleoli in human early erythroblasts (K2, K1, K1/2 cells).

Science.gov (United States)

Smetana, K; Jirásková, I; Klamová, H

2005-01-01

Human early erythroid precursors classified according to the nuclear size were studied to provide information on nucleoli in these cells using simple cytochemical procedures for demonstration of RNA and proteins of silver-stained nucleolar organizers. K2 cells with nuclear diameter larger than 13 microm and K1 cells with nuclear diameter larger than 9 microm corresponding to proerythroblasts and macroblasts (large basophilic erythroblasts) mostly possessed large irregularly shaped nucleoli with multiple fibrillar centres representing "active nucleoli". K1/2 cells with nuclear diameter smaller than 9 microm corresponding to small basophilic erythroblasts were usually characterized by the presence of micronucleoli representing "inactive nucleolar types". On the other hand, a few K1/2 cells contained large nucleoli with multiple fibrillar centres similar to those present in K2 cells and thus appeared as "microproerythroblasts". The nucleolar asynchrony expressed by the presence of large irregularly shaped nucleoli with multiple nucleoli (active nucleoli) and ring-shaped nucleoli (resting nucleoli) in one and the same nucleus of K2 or K1 cells was not exceptional and might reflect a larger resistance of these cells to negative factors influencing the erythropoiesis. The intranucleolar translocation of silver-stained nucleolus organized regions was noted in K2 cells and might indicate the premature aging of these cells without further differentiation. More studies, however, are required in this direction.

Integrating a Career Planning and Development Program into the Baccalaureate Nursing Curriculum. Part II. Outcomes for New Graduate Nurses 12 Months Post-Graduation.

Waddell, Janice; Spalding, Karen; Navarro, Justine; Jancar, Sonya; Canizares, Genevieve

2015-11-28

New graduate nurses' (NGNs) transition into the nursing workforce is characterized as stressful and challenging. Consequently, a high percentage of them leave their first place of employment or the profession entirely within one year of graduation. Nursing literature describes this complicated shift from student to registered nurse, however, limited attention has focused on strategies that could be implemented during students' academic programs to prepare them for this difficult transition period. Therefore, a longitudinal intervention study was conducted to examine the influence of a career planning and development (CPD) program on the development of career resilience in baccalaureate nursing students and at 12 months post-graduation (NGN). The findings support including structured and progressive curriculum-based CPD opportunities in academic programs, not only for the positive outcomes that accrue to students, but also because of the benefits they extend to NGNs as they make the transition to their first professional nursing role.

A hybrid classroom-online curriculum format for RN-BSN students: cohort support and curriculum structure improve graduation rates.

Science.gov (United States)

Davidson, Susan C; Metzger, Richard; Lindgren, Katherine S

2011-05-01

As more registered nurses (RNs) return to school to obtain a bachelor of science in nursing (BSN), innovative ways must be found to support them in this endeavor. Barriers for RNs who return to school include scheduling of coursework and fear of failure. One school of nursing with a traditional BSN program reviewed its RN-BSN track, with its low retention and graduation rates. With input from nursing leaders and nurses in the community, the school applied for and was awarded a 3-year Health Resources and Services Administration grant to redesign the RN-BSN program. A hybrid classroom-online curriculum is offered in a structured, sequential format so that the RNs are admitted once a year and must complete the courses as a group, in a cohort. Data collected from evaluations showed that program support, technology support, and social support from peers encouraged the RNs to "stay the course," and 100% completed the requirements to graduate.

Tedesche, M. E.; Conner, L.

2015-12-01

Well rounded scientific researchers are not only experts in their field, but can also communicate their work to a multitude of various audiences, including the general public and undergraduate university students. Training in these areas should ideally start during graduate school, but many programs are not preparing students to effectively communicate their work. Here, we present results from the NSF-funded CASE (Changing Alaska Science Education) program, which was funded by NSF under the auspices of the GK-12 program. CASE placed science graduate students (fellows) in K-12 classrooms to teach alongside of K-12 teachers with the goal of enhancing communication and teaching skills among graduate students. CASE trained fellows in inquiry-based and experiential techniques and emphasized the integration of art, writing, and traditional Alaska Native knowledge in the classroom. Such techniques are especially effective in engaging students from underrepresented groups. As a result of participation, many CASE fellows have reported increased skills in communication and teaching, as well as in time management. These skills may prove directly applicable to higher education when teaching undergraduate students.

Incorporating K-12 students in scientific research processes and opportunities in their communities is a great way to bridge the gap between research and education and to start building science research capacity at an early age. One goal of the Experimental Program to Stimulate Competitive Research (EPSCoR) Alaska Adapting to Changing Environments project is to engage the local community in the research as well as to share results with the people. By giving K-12 students Global Positioning System (GPS) units, and allowing them to collect and map their own data, they are being exposed to some of the research methods being used by scientists in the Alaska ACE project. This hands-on, minds-on method has been successfully used in formal education settings such as a Junior High School classroom in Nuiqsut, Alaska as well as in informal education settings such as summer camps in Barrow, Alaska and Kenai, Alaska. The students progress from mapping by hand to collecting location data with their GPS units and cameras, and imputing this information into ArcGIS Online to create map products. The data collected were from sites ranging from important places in the community to sites visited during summer camps, with students reflecting on data and site significance. Collecting data, using technology, and creating map products contribute to science skills and practices students need to conduct research of their own and to understand research being done around them. The goal of this education outreach implementation is to bring students closer to the research, understand the process of science, and have the students continue to collect data and contribute to research in their communities. Support provided for this work from the Alaska EPSCoR NSF Award #OIA-1208927 and the state of Alaska is gratefully acknowledged.

Cataclysms and Catastrophes: A Case Study of Improving K-12 Science Education Through a University Partnership

Science.gov (United States)

Fennell, T.; Ellins, K. K.; Morris, M.; Christeson, G.

2003-12-01

The K-12 science teacher is always seeking ways of improving and updating their curriculum by integrating the latest research into their most effective classroom activities. However, the daily demands of delivering instruction to large numbers of students coupled with the rapid advances in some fields of science can often overwhelm this effort. The NSF-sponsored Cataclysms and Catastrophes curriculum, developed by scientists from the The University of Texas at Austin Institute for Geophysics (UTIG) and Bureau of Economic Geology (BEG), middle and high school teachers, and UT graduate students (NSF GK-12 fellows) working together through the GK-12 program, is a textbook example of how universities can facilitate this quest, benefiting education at both K-12 and university levels. In 1992, "The Great K-T Extinction Debate" was developed as an activity in the Planet Earth class at the Liberal Arts and Science Academy of Austin as an interdisciplinary approach to science. Taking advantage of the media attention generated by the impact scenario for the K-T extinction, the activity consists of students participating in a simulated senate hearing on the potential causes of the K-T extinction and their implications for society today. This activity not only exposes students to the wide range of science involved in understanding mass extinctions, but also to the social, political and economic implications when this science is brought into the public arena and the corresponding use of data in decision making and disaster preparedness. While "The Great K-T Extinction Debate" was always a popular and effective activity with students, it was in desperate need of updating to keep pace with the evolving scientific debate over the cause of the K-T extinction and the growing body of impact evidence discovered over the past decade. By adding two inquiry-based learning activities that use real geophysical data collected by scientists studying the buried Chicxulub feature as a

2012-12-01

To better prepare tomorrow's leaders, it is of utmost importance that today's teachers are science literate. To meet that need, the American Meteorological Society (AMS) Education Program offers content-rich, professional development courses and training workshops for precollege teachers in the geosciences. During the fall and spring semesters, the AMS in partnership with NOAA, NASA, and SUNY Brockport, offers a suite of pre-college teacher development courses, DataStreme Atmosphere, DataStreme Ocean and DataStreme Earth's Climate System (ECS). These courses are delivered to small groups of K-12 teachers through Local Implementation Teams (LITs) positioned throughout the U.S. The courses use current, real-world environmental data to investigate the atmosphere, ocean, and climate system and consist of weekly online study materials, weekly mentoring, and several face-to-face meetings, all supplemented by a provided textbook and investigations manual. DataStreme ECS takes an innovative approach to studying climate science, by exploring the fundamental science of Earth's climate system and addressing the societal impacts relevant to today's students and teachers. The course investigates natural and human forcings and feedbacks to examine mitigation and adaptation strategies for the future. Information and data from respected organizations, such as the IPCC, the US Global Change Research Program, NASA, and NOAA are used throughout the course, including in the online and printed investigations. In addition, participants differentiate between climate, climate variability, and climate change through the AMS Conceptual Energy Model, a basic climate model that follows the flow of energy from space to Earth and back. Participants also have access to NASA's EdGCM, a research-grade Global Climate Model where they can explore various future climate scenarios in the same way that actual research scientists do. Throughout all of the courses, teachers have the opportunity to expand

Initiating New Science Partnerships in Rural Education (INSPIRE) is a five-year partnership between Mississippi State University and three nearby school districts. The primary goal of the program is to strengthen the communication and scientific reasoning skills of graduate students in geosciences, physics, chemistry, and engineering by placing them in area middle school and high school science and mathematics classrooms for ten hours a week for an entire academic year as they continue to conduct their thesis or dissertation research. Additional impacts include increased content knowledge for our partner teachers and improvement in the quality of classroom instruction using hands-on inquiry-based activities that incorporate ideas used in the research conducted by the graduate students. Current technologies, such as Google Earth, GIS, Celestia, benchtop SEM and GCMS, are incorporated into many of the lessons. Now in the third year of our program, we will present the results of our program to date, including an overview of documented graduate student, teacher, and secondary student achievements, the kinds of activities the graduate students and participating teachers have developed for classroom instruction, and the accomplishments resulting from our four international partnerships. INSPIRE is funded by the Graduate K-12 (GK-12) STEM Fellowship Program (Award No. DGE-0947419), which is part of the Division for Graduate Education of the National Science Foundation.

2018-03-19

Social media (SoMe) have revolutionized healthcare, but physicians remain hesitant to adopt SoMe in their practices. We sought to assess graduating urology residents' practices of and attitudes toward SoMe. A close-ended questionnaire, employing five-point Likert scales, was distributed to all final-year residents (n=100) in Canadian urology training programs in 2012, 2014, and 2016 to assess SoMe usage and perceived usefulness. All (100%) questionnaires were completed. Respondents frequently used online services for personal (100%) and professional (96%) purposes. Most (92%) used SoMe. Many (73%) frequently used SoMe for personal purposes, but few (12%) frequently used SoMe for professional purposes. While a majority (59%) opposed direct patient interaction online, most supported using SoMe to provide patients with static information (76%) and collaborate with colleagues (65%). Many (70-73%) were optimistic that novel solutions to privacy issues in online communications will arise, making SoMe and email contact with patients conceivable. Few (2-8%) were aware and had read guidelines and legislations regarding physician online practices; however, awareness of medical associations' and institutional SoMe policies significantly increased over time (pprofessional settings and were wary of using it in patient care. Nevertheless, they were optimistic toward its integration in urology and supported its use in physician-physician communication. Considering SoMe's increased influence on urology and graduating residents' limited awareness of guidelines and legislations, postgraduate medical educators should encourage residents to become more familiar with current online communication recommendations.

NSF GK-12 Fellows as Mentors for K-12 Teachers Participating in Field Research Experiences

Science.gov (United States)

Ellins, K.; Perry, E.

2005-12-01

The University of Texas Institute for Geophysics (UTIG) recognizes the value of providing educational opportunities to K-12 teachers who play a critical role in shaping the minds of young people who are the future of our science. To that end, UTIG established the "Texas Teachers in the Field" program in 2000 to formalize the participation of K-12 teachers in field programs that included UTIG scientists. In 2002, "Texas Teachers in the Field" evolved through UTIG's involvement in a University of Texas at Austin GK-12 project led by the Environmental Sciences Institute, which enabled UTIG to partner a subset of GK-12 Fellows with teachers participating in geophysical field programs. During the three years of the GK-12 project, UTIG successfully partnered four GK-12 Fellows with five K-12 teachers. The Fellows served as mentors to the teachers, as liaisons between UTIG scientists leading field programs and teachers and their students, and as resources in science, mathematics, and technology instruction. Specifically, Fellows prepared teachers and their students for the field investigations, supervised the design of individual Teacher Research Experience (TRE) projects, and helped teachers to develop standards-aligned curriculum resources related to the field program for use in their own classrooms, as well as broader distribution. Although all but one TRE occurred during the school year, Texas school districts and principals were willing to release teachers to participate because the experience and destinations were so extraordinary (i.e., a land-based program in Tierra del Fuego, Argentina; and research cruises to the Southeast Caribbean Sea and Hess Deep in the Pacific Ocean) and carried opportunities to work with scientists from around the world. This exceptional collaboration of GK-12 Fellows, K-12 teachers and research scientists enriches K-12 student learning and promotes greater enthusiasm for science.

Online Assessment, Measurement and Evaluation Case Studies from Higher Education, K-12 and Corporate

Directory of Open Access Journals (Sweden)

Reviewed by Dr. Adnan BOYACI

2006-01-01

Full Text Available With the revolution occurred in communication technologies at the beginning of 1990’s, network technologies have emerged as the challenging parameters accelerating improvements of instructional technologies. Online classrooms and management of them appeared as a new domain which necessitates a new paradigm different from the classical ones. User and instructor friendly learning context and management systems (LCMS have brought new approaches, techniques and tools for the assessment and measurement processes. These approaches, techniques and tools embedded in LCMS have redefined not only the way teachers teach but also students learn. WebCT, Blackboard and eCollege and many others as the online instructional environments have provided new opportunities to construct a coherent instructional system which has never been used as a unique environment any before. Assessment and measurement have been redefined within this framework. The successes of assessment and measurement methodologies or system inevitably depend on conceptualization and then implementation to different educational settings.

The Lewis Center for Educational Research (LCER) and the Jet Propulsion Laboratory (JPL) collaborate in a K-12 educational project in which students conduct observations for several research programs led by radio astronomers. The Goldstone-Apple Valley Radio Telescope (GAVRT) program provides participating teachers with curriculum elements, based on the students' observing experiences, which support national and state academic standards. The current program is based on 2.2-GHz and 8.4-GHz radiometric observations of variable sources. The research programs monitor Jupiter, Uranus, and a selected set of quasars. The telescope is a decommissioned NASA Deep Space Network antenna at Goldstone, California. In the next three years, a second telescope will be added. This telescope will at least operate at the above frequencies as well as 6 GHz and 12 GHz. Possibly, it will operate in a continuous band from 1.2 GHz to 14 GHz. In either case, the telescope will be able to observe at least the 6.6-GHz and 12.2-GHz methanol maser lines. The success of the GAVRT program depends critically on the participation of scientists committed to the research who have the ability and enthusiasm for interacting with K-12 students, typically through teleconferences. The scientists will initially work with the LCER staff to create curriculum elements around their observing program.

2013-04-01

The Soil Science Society of America created its K12 Committee in 2006 in part to compliment the Dig It! The Secrets of Soil exhibit that opened in July 2008 at the Smithsonian's Institution's Nation Museum of Natural History (of which SSS was a founding sponsor). The committee's work began quickly with a website designed to provide resources for K12 teachers. The first accomplishments included reviewing and posting links to web based information already available to teachers. These links were sorted by subject and grade level to make it easier for teachers to navigate the web and find what they needed quickly. Several presentations and lessons designed for K12 teachers were also posted at this time. Concurrent with this effort a subcommittee review and organized the national teaching standards to show where soils could fit into the overall K12 curriculum. As the website was being developed another subcommittee developed a soils book (Soil! Get the Inside Scoop, 2008) to further compliment the Dig It! exhibit. This was a new endeavor for SSSA having never worked with the non-academic audience in developing a book. Peer-reviews of this book included not only scientist but also students in order to make sure the book was attractive to them. Once the book was published and the website developed it became clear more outreach was needed. SSSA K12 Committee has attended both the National Science Teachers Association (since 2008) the USA Science and Engineering Festival (since 2010) with exhibits and workshops. It has cooperated and contributed to the American Geologic Institutes' Earth Science Week materials with brochures and lesson plans and with National Association of Conservation Districts by providing peer-review and distribution of materials. The most recent developments from the committee include a web redesign that is more student and teacher friendly, the development of a peer-review system to publish K12 Lesson Plans, and finally the publication of a new soils

2014-12-01

Physics education research (PER) is a rapidly growing area of PhD specialization. In this article we examine the trajectories that led respondents into a PER graduate program as well as their expected future trajectories. Data were collected in the form of an online survey sent to graduate students in PER. Our findings show a lack of visibility of PER as a field of study, a dominance of work at the undergraduate level, and a mismatch of future desires and expectations. We suggest that greater exposure is needed so PER is known as a field of inquiry for graduates, that more emphasis should be placed on research beyond the undergraduate level, and that there needs to be stronger communication to graduate students about potential careers.

Efficacy of the World Wide Web in K-12 environmental education

Science.gov (United States)

York, Kimberly Jane

1998-11-01

Despite support by teachers, students, and the American public in general, environmental education is not a priority in U.S. schools. Teachers face many barriers to integrating environmental education into K--12 curricula. The focus of this research is teachers' lack of access to environmental education resources. New educational reforms combined with emerging mass communication technologies such as the Internet and World Wide Web present new opportunities for the infusion of environmental content into the curriculum. New technologies can connect teachers and students to a wealth of resources previously unavailable to them. However, significant barriers to using technologies exist that must be overcome to make this promise a reality. Web-based environmental education is a new field and research is urgently needed. If teachers are to use the Web meaningfully in their classrooms, it is essential that their attitudes and perceptions about using this new technology be brought to light. Therefore, this exploratory research investigates teachers' attitudes toward using the Web to share environmental education resources. Both qualitative and quantitative methods were used to investigate this problem. Two surveys were conducted---self-administered mail survey and a Web-based online survey---to elicit teachers perceptions and comments about environmental education and the Web. Preliminary statistical procedures including frequencies, percentages and correlational measures were performed to interpret the data.

Given the increasing number of endocrine surgery fellowship graduates, we investigated if expectations and job opportunities changed over time. American Association of Endocrine Surgeons (AAES) fellowship graduates, surgery department chairs, and physician recruiters were surveyed. Univariate analysis was performed with JMP Pro 12 software. We identified 141 graduates from 2008-2015; survey response rate was 72% (n = 101). Compared to earlier graduates, fewer academic opportunities were available for the recent graduates who intended to join them (P = .001). Unlike earlier graduates, recent graduates expected to also perform elective general surgery, which ultimately represented a greater percentage of their practices (both P job offers decreased. Overall, 84% of graduates matched their intended practice type and 98% reported being satisfied. Reponses from graduates, department chairs, and physician recruiters highlighted opportunities to improve mentor involvement, job search strategies, and online job board utilization. The endocrine surgery job market has diversified resulting in more graduates entering nonacademic practices and performing general surgery. This rapid evolution supports future analyses of the job market and opportunities for job creation. Almost every graduate reported job satisfaction, which encourages graduates to consider joining both academic and nonacademic practices equally. Copyright © 2016 Elsevier Inc. All rights reserved.

Full Text Available Information technology has a potential to be the answer to one of Africa’s most pressing problems- providing education to a number of geographically dispersed learners, who currently have to leave their countries for a number of years in order to pursue their studies elsewhere. The School of Nursing at the University of Natal launched an online graduate course in nursing education at the beginning of the year 2000 for the first time as part of a masters degree programme. A number of lessons have been learned from this experience. Firstly, it took too long to arrive at ‘closure’ on discussion of any one particular theme. There seemed to be a perpetual feeling of never “completing” teaching/learning tasks. Ordinarily, in a face-to-face (f2f classroom, a particular theme or topic is scheduled for a particular lecture period. More often than not, whether clarity and/or resolution has been attained, the discussion moves on to the next theme, or topic. This has not been easy to do in computer mediated communication (CMC. The students’ contributions, however, seemed more thought out and more focused than had been the case in the f2f classes. Secondly, the essentiality/importance of structure became apparent very early. After an initial tentative and slow start, once the students felt comfortable with the computer “classroom” , the bulletin board was flooded with messages, necessitating re-thinking the original structure.

Terry Müller

2008-06-01

Full Text Available Although online courses at postsecondary institutions promise adults access, flexibility, and convenience, many barriers to online learning remain. This article presents findings from a qualitative case study, which explored the phenomenon of undergraduate and graduate women learners’ persistence in online degree-completion programs at a college in the Northeast of the United States. Research questions asked why women learners persisted or failed to persist, and how factors supporting or hindering persistence influenced learners. Interviews with a purposeful sample of 20 participants revealed the complexity of variables affecting learners’ persistence to graduation. Findings suggested that multiple responsibilities, insufficient interaction with faculty, technology, and coursework ranked highest as barriers to women’s persistence. Strong motivation to complete degrees, engagement in the learning community, and appreciation for the convenience of an online degree-completion option facilitated persistence.

Burrell, S.

2012-12-01

Given low course enrollment in geoscience courses, retention in undergraduate geoscience courses, and granting of BA and advanced degrees in the Earth sciences an effective strategy to increase participation in this field is necessary. In response, as K-12 education is a conduit to college education and the future workforce, Earth science education at the K-12 level was targeted with the development of teacher professional development around Earth system science, inquiry and problem-based learning. An NSF, NOAA and NASA funded effort through the Institute for Global Environmental Strategies led to the development of the Earth System Science Educational Alliance (ESSEA) and dissemination of interdisciplinary Earth science content modules accessible to the public and educators. These modules formed the basis for two teacher workshops, two graduate level courses for in-service teachers and two university course for undergraduate teacher candidates. Data from all three models will be presented with emphasis on the teacher workshop. Essential components of the workshop model include: teaching and modeling Earth system science analysis; teacher development of interdisciplinary, problem-based academic units for implementation in the classroom; teacher collaboration; daily workshop evaluations; classroom observations; follow-up collaborative meetings/think tanks; and the building of an on-line professional community for continued communication and exchange of best practices. Preliminary data indicate increased understanding of Earth system science, proficiency with Earth system science analysis, and renewed interest in innovative delivery of content amongst teachers. Teacher-participants reported increased student engagement in learning with the implementation of problem-based investigations in Earth science and Earth system science thinking in the classroom, however, increased enthusiasm of the teacher acted as a contributing factor.

The WestEd Eisenhower Regional Consortium (WERC) is in its second year of offering two Earth Systems Science On-line Graduate courses from IGES - one for High School teachers, and one for Middle School teachers. These high-quality courses support WERC's commitment to "supporting increased scientific and mathematical literacy among our nation's youth through services and other support aimed at enhancing the efforts of those who provide K-12 science and mathematics education." WERC has been able to use its EdGateway online community network to offer these courses to environmental education and science teachers nationwide. Through partnerships with the North American Association for Environmental Education (NAAEE), the National Environmental Education Advancement Project (NEEAP), and other regional, state and local science and environmental education organizations, WERC has a broad reach in connecting with science educators nationwide. WERC manages several state and national listservs, which enable us to reach thousands of educators with information about the courses. EdGateway also provides a private online community in which we offer the courses. WERC partners with two Master Teachers from Utah, who facilitate the courses, and with the Center for Science and Mathematics Education at Weber State University, who provides low-cost graduate credit for the courses. Our students have included classroom teachers from upper elementary through high school, community college science teachers, and environmental science center staff who provide inservice for teachers. Educators from Hawaii to New Jersey have provided diverse personal experiences of Earth Systems Science events, and add richness to the online discussions. Two Earth Science Experts, Dr. Rick Ford from Weber State University, and Dr. Art Sussman from WestEd also contribute to the high caliber of learning the students experience in the courses.

2009-02-01

This article describes the authors' experiences during 3 years of using Microsoft Excel to teach graduate-level statistics, as part of the research core required by the American Association of Colleges of Nursing for all professional graduate nursing programs. The advantages to using this program instead of specialized statistical programs are ease of accessibility, increased transferability of skills, and reduced cost for students. The authors share their insight about realistic goals for teaching statistics to master's-level students and the resources that are available to faculty to help them to learn and use Excel in their courses. Several online sites that are excellent resources for both faculty and students are discussed. Detailed attention is given to an online course (Carnegie-Mellon University Open Learning Initiative, n.d.), which the authors have incorporated into their graduate-level research methods course.

Systematic study of K+ and K- charge exchange at 8.36 and 12.8 GeV/c

International Nuclear Information System (INIS)

Gilchriese, M.G.D.

1977-08-01

The results of a wire chamber spectrometer experiment at the Stanford Linear Accelerator Center to study kaon charge exchange reactions are reported. The salient experimental features include good relative normalization between the K + and K - charge exchange reactions and a large increase, with respect to previous experiments, in the number of events obtained for K + n charge exchange at the higher energy. Approximately 1500 events at 12.8 GeV/c and 250 events at 8.36 GeV/c were obtained for each of the reactions K + n → K 0 p, K - p → anti K 0 n, K + p → K 0 Δ 2+ and K - n → anti K 0 Δ - . The results of the experiment show that the K + charge exchange cross sections are larger than the K - cross sections at both energies. In particular it is found that sigma/sub tot/ (K + n → K 0 p)/sigma/sub tot/ (K - p → anti K 0 n) is 1.37 +- 0.22 at 8.36 GeV/c and 1.38 +- 0.09 at 12.8 GeV/c. The ratio of these two reactions is also consistent with no momentum transfer dependence at either beam energy. Similarly it was determined that sigma/sub tot/ (K + p → K 0 Δ 2+ )/sigma/sub tot/ (K - n → anti K 0 Δ - ) is 1.05 +- 0.16 at 8.36 GeV/c and 1.56 +- 0.08 at 12.8 GeV/c. The ratio of these two reactions is also consistent with momentum transfer independence for both beam energies. These results are in clear conflict with the predictions of exchange degenerate Regge pole models

2010-02-01

Professional development courses offered in physical/Earth science and physics by the Department of Physics are delivered by different venues to accommodate the needs of the K-12 teaching community. The majority of teachers take our courses off-site or through our distance-learning web-based program on the Internet for endorsement or recertification, but with a gradually increasing number enrolling in our 30 credit Masters of Arts in Physics Education degree (MAPE) program. The purpose of the Masters program is to provide increased physics content to those teachers who feel inadequately prepared to teach high school physics. The increase in numbers and success of this program is partly due to the convenience of taking online web-based courses which is made possible by using the latest communication technologies on the high speed internet. There is also a residential component of the MAPE program, which requires the candidates to earn 14 credits of calculus-based core physics in residence in the summer at the University. We have graduated a total of 91 teachers since the program began in 2000. )

The collisional excitation transfer for the processes Rb * (5P 3/2 ) + K(4S 1/2 ) → Rb(5S 1/2 ) + K * (4P J ), J = 1/2, 3/2, was investigated using two-photon laser excitation techniques with a thermionic heat-pipe diode as a detector. The population densities of the K 4P J levels induced by collisions with excited Rb atoms as well as those produced by direct laser excitation of the potassium atoms were probed through the measurement of the thermionic signals generated due to the ionization of the potassium atoms emerging from the K(4P J ) → K(7S 1/2 ) excitation channel.

The Initiating New Science Partnerships in Rural Education (INSPIRE) program at Mississippi State University (MSU), funded by the NSF Graduate STEM Fellows in K-12 Education (GK12) program, focuses on the advancement of Earth and Space science education in K-12 classrooms. INSPIRE currently in its third year of partnering ten graduate students each year from the STEM fields of Geosciences, Engineering, Physics and Chemistry at MSU with five teachers from local, rural school districts. The five year project serves to enhance graduate student's communication skills as they create interactive lessons linking their STEM research focus to the state and national standards covered in science and math classrooms for grades 7-12 through inquiry experiences. Each graduate student is responsible for the development of two lessons each month of the school year that include an aspect of their STEM research, including the technologies that they may utilize to conduct their STEM research. The plans are then published on the INSPIRE project webpage, www.gk12.msstate.edu, where they are a free resource for any K-12 classroom teacher seeking innovative activities for their classrooms and total over 300 lesson activities to date. Many of the participating teachers and graduate students share activities developed with non-participating teachers, expanding INSPIRE's outreach of incorporating STEM research into activities for K-12 students throughout the local community. Examples of STEM research connections to classroom topics related to earth and ocean science include activities using GPS with GIS for triangulation and measurement of area in geometry; biogeochemical response to oil spills compared to organism digestive system; hydrogeology water quality monitoring and GIS images used as a determinant for habitat suitability in area water; interactions of acids and bases in the Earth's environments and surfaces; and the importance of electrical circuitry in an electrode used in

Learners' perceived information overload in online learning via computer-mediated communication

Karen L. Murphy

2011-12-01

Full Text Available Many studies report information overload as one of the main problems that students encounter in online learning via computer-mediated communication. This study aimed to explore the sources of online students' information overload and offer suggestions for increasing students' cognitive resources for learning. Participants were 12 graduate students from two online courses in the United States. Their learning experiences in both online discussions and on the course website were explored through semi-structured interviews. They also completed a background questionnaire that assessed three constructs that limit learner readiness and are likely to lead to online students' perceived information overload: inadequate prior knowledge, inadequate English proficiency, and lack of technical skills for participating in computer-mediated communications. The findings suggest that varied learner characteristics led some students to be more susceptible than others to information overload. Emerging data-driven risk factors were: lack of efficiency in reading from computer screens, visual and auditory learning preferences, and time constraints. Difficulties associated with students' perceptions of information overload are addressed and implications for course design are offered.

Developing Partnerships between Higher Education Faculty, K-12 Science Teachers, and School Administrators via MSP initiatives: The RITES Model

Science.gov (United States)

Caulkins, J. L.; Kortz, K. M.; Murray, D. P.

2011-12-01

The Rhode Island Technology Enhanced Science Project (RITES) is a NSF-funded Math and Science Partnership (MSP) project that seeks to improve science education. RITES is, at its core, a unique partnership that fosters relationships between middle and high school science teachers, district and school administrators, higher education (HE) faculty members, and science education researchers. Their common goal is to enhance scientific inquiry, increase classroom technology usage, and improve state level science test scores. In one of the more visible examples of this partnership, middle and high school science teachers work closely with HE science faculty partners to design and teach professional development (PD) workshops. The PD sessions focus on technology-enhanced scientific investigations (e.g. use of probes, online simulations, etc.), exemplify inquiry-based instruction, and relate expert content knowledge. Teachers from these sessions express substantial satisfaction in the program, report increased comfort levels in teaching the presented materials (both via post-workshop surveys), and show significant gains in content knowledge (via pre-post assessments). Other benefits to this kind of partnership, in which K-12 and HE teachers are considered equals, include: 1) K-12 teachers are empowered through interactions with HE faculty and other science teachers in the state; 2) HE instructors become more informed not only about good pedagogical practices, but also practical aspects of teaching science such as engaging students; and 3) the PD sessions tend to be much stronger than ones designed and presented solely by HE scientists, for while HE instructors provide content expertise, K-12 teachers provide expertise in K-12 classroom practice and implementation. Lastly, the partnership is mutually beneficial for the partners involved because both sides learn practical ways to teach science and inquiry at different levels. In addition to HE faculty and K-12 science teacher

Education professionals and seismologists under the emerging SUN (Shaking Up Nevada) program are leveraging the existing infrastructure of the real-time Nevada K-12 Seismic Network to provide a unique inquiry based science experience for teachers. The concept and effort are driven by teacher needs and emphasize rigorous content knowledge acquisition coupled with the translation of that knowledge into an integrated seismology based earth sciences curriculum development process. We are developing a pedagogical framework, graduate level coursework, and materials to initiate the SUN model for teacher professional development in an effort to integrate the research benefits of real-time seismic data with science education needs in Nevada. A component of SUN is to evaluate teacher acquisition of qualified seismological and earth science information and pedagogy both in workshops and in the classroom and to assess the impact on student achievement. SUN's mission is to positively impact earth science education practices. With the upcoming EarthScope initiative, the program is timely and will incorporate EarthScope real-time seismic data (USArray) and educational materials in graduate course materials and teacher development programs. A number of schools in Nevada are contributing real-time data from both inexpensive and high-quality seismographs that are integrated with Nevada regional seismic network operations as well as the IRIS DMC. A powerful and unique component of the Nevada technology model is that schools can receive "stable" continuous live data feeds from 100's seismograph stations in Nevada, California and world (including live data from Earthworm systems and the IRIS DMC BUD - Buffer of Uniform Data). Students and teachers see their own networked seismograph station within a global context, as participants in regional and global monitoring. The robust real-time Internet communications protocols invoked in the Nevada network provide for local data acquisition

This report contains the detailed description of an experiment which has determined the differential cross section of the K - n→K - n elastic scattering reaction. The results are 12 angular distributions spanning the K - n c.m. energy interval from approximately 1.86 to approximately 2.32 GeV. The measurements have been performed at the CERN PS using a beam of negative kaons with momenta from 1.2 to 2.2 GeV/c incident on a liquid deuterium target. By means of electronic apparatus the process K - d→K - n psub(s) was identified and recorded; this process is basically the same as the K - n elastic reaction insofar as the spectator proton psub(s) has low momentum. The elastic reaction was derived from the above process by taking into account the Fermi motion of the target neutron and by introducing the appropriate corrections to compensate for the effects due to the composite nature of the neutron (double-scattering, final state interaction). These results, constituting the first extensive collection of data on the pure isospin 1 anti KN state have been used in conjunction with other data in a preliminary partial wave analysis of the anti KN elastic system over the c.m. energy range from 1.84 to 2.23 GeV. Mainly for testing purposes, a similar amount of data has been collected for the K - p elastic reaction also from K - d collisions (K - d→K - p nsub(s)). (Auth.)

Career choices on graduation--a study of recent graduates from University College Cork.

LENUS (Irish Health Repository)

McKenna, Gerald

2010-04-23

INTRODUCTION: Irish dental graduates are eligible to enter general dental practice immediately after qualification. Unlike their United Kingdom counterparts, there is no requirement to undertake vocational training (VT) or any pre-registration training. VT is a mandatory 12-month period for all UK dental graduates who wish to work within the National Health Service. It provides structured, supervised experience in training practices and through organised study days. AIMS: This study aimed to profile the career choices made by recent dental graduates from UCC. It aimed to record the uptake of VT and associate posts, and where the graduates gained employment. METHODOLOGY: A self-completion questionnaire was developed and circulated electronically to recent graduates from UCC. An existing database of email addresses was used and responses were returned by post or by email. A copy of the questionnaire used is included as Appendix 1. RESULTS: Questionnaires were distributed over an eight-week period and 142 were returned, giving a response rate of 68.90%. Responses were gathered from those who graduated between 2001 and 2007; however, the majority came from more recent classes. Overall, the majority of graduates took up associate positions after qualification (71.8%) with smaller numbers undertaking VT (28.2%). Increasing numbers have entered VT in recent years, including 54.3% from the class of 2007. Overall, the majority of graduates initially took up positions in England (43%); however, in recent times more have been employed in Scotland. Subsequent work profiles of the graduates illustrate that the majority are now working as associates in general practice (51.4%) and in Ireland (54.2%). CONCLUSIONS: There has been an increase in the proportion of UCC graduates undertaking VT. Graduates tended to move away from Ireland initially to gain employment. There has been a shift away from employment in England towards Scotland where the majority of new UCC graduates are now

2013-02-01

Full Text Available Abstract Background Screening for mental disorders among disability claimants is important, since mental disorders seem to be seriously under-recognized in this population. However, performance of potentially suitable scales is unknown. We aimed to evaluate the psychometric properties of three scales, the 10- and 6-item Kessler Psychological Distress Scale (K10, K6 and the 12-item General Health Questionnaire (GHQ-12, to predict present state mental disorders, classified according to the Diagnostic and Statistical Manual of Mental Disorders, 4thEdition (DSM-IV among disability claimants. Methods All scales were completed by a representative sample of persons claiming disability benefit after two years sickness absence (n=293. All diagnoses, both somatic and mental, were included. The gold standard was the Composite International Diagnostic Interview (CIDI 3.0 to diagnose present state DSM-IV disorder. Cronbach’s α, sensitivity, specificity, positive (PPV and negative predictive values (NPV, and the areas under the Receiver Operating Characteristic curve (AUC were calculated. Results Cronbach’s alpha’s were 0.919 (K10, 0.882 (K6 and 0.906 (GHQ-12. The optimal cut-off scores were 24 (K10, 14 ( K6 and 20 (GHQ-12. The PPV and the NPV for the optimal cut point of the K10 was 0.53 and 0.89, for the K6 0.51 and 0.87, and for the GHQ-12 0.50 and 0.82. The AUC’s for 30-day cases were 0.806 (K10; 95% CI 0.749-0.862, 0.796 (K6; 95% CI 0.737-0.854 and 0.695 (GHQ-12; 95% CI 0.626-0.765. Conclusions The K10 and K6 are reliable and valid scales to screen for present state DSM-IV mental disorder. The optimal cut-off scores are 24 (K10 and 14 (K6. The GHQ-12 (optimal cut-off score: 20 is outperformed by the K10 and K6, which are to be preferred above the GHQ-12. The scores on separate items of the K10 and K6 can be used in disability assessment settings as an agenda for an in-depth follow-up clinical interview to ascertain the presence of present state

Development of an Attitude Scale to Assess K-12 Teachers' Attitudes toward Nanotechnology

Science.gov (United States)

Lan, Yu-Ling

2012-05-01

To maximize the contributions of nanotechnology to this society, at least 60 countries have put efforts into this field. In Taiwan, a government-funded K-12 Nanotechnology Programme was established to train K-12 teachers with adequate nanotechnology literacy to foster the next generation of Taiwanese people with sufficient knowledge in nanotechnology. In the present study, the Nanotechnology Attitude Scale for K-12 teachers (NAS-T) was developed to assess K-12 teachers' attitudes toward nanotechnology. The NAS-T included 23 Likert-scale items that can be grouped into three components: importance of nanotechnology, affective tendencies in science teaching, and behavioural tendencies to teach nanotechnology. A sample of 233 K-12 teachers who have participated in the K-12 Nanotechnology Programme was included in the present study to investigate the psychometric properties of the NAS-T. The exploratory factor analysis of this teacher sample suggested that the NAS-T was a three-factor model that explained 64.11% of the total variances. This model was also confirmed by the confirmatory factor analysis to validate the factor structure of the NAS-T. The Cronbach's alpha values of three NAS-T subscales ranged from 0.89 to 0.95. Moderate to strong correlations among teachers' NAS-T domain scores, self-perception of own nanoscience knowledge, and their science-teaching efficacy demonstrated good convergent validity of the NAS-T. As a whole, psychometric properties of the NAS-T indicated that this instrument is an effective instrument for assessing K-12 teachers' attitudes toward nanotechnology. The NAS-T will serve as a valuable tool to evaluate teachers' attitude changes after participating in the K-12 Nanotechnology Programme.

Pintz, Christine; Posey, Laurie

2013-07-01

This paper describes the development and preliminary evaluation of an eLearning program intended to provide incoming nursing students with the basic knowledge, skills and abilities needed to succeed in graduate-level, online coursework. Using Mayer's principles (2008) for the effective design of multimedia instruction, an open-access, self-directed, online program was developed. The Graduate School Boot Camp includes five online modules focused on learning strategies and time management, academic writing, technology, research, and library skills. To motivate and engage learners, the program integrates a fun, graphical sports theme with audiovisual presentations, examples, demonstrations and practice exercises. Learners begin with a self-assessment based on the Motivated Strategies for Learning Questionnaire or MSLQ (Pintrich et al., 1993). To assess change in knowledge levels before and after completing the program, learners take a pre-test and post-test. Preliminary findings indicate that the students found the information relevant and useful. They enjoyed the self-paced, multimedia format, and liked the option to return to specific content later. This innovative program offers a way to prepare students proactively, and may prove useful in identifying students at risk and connecting them with the appropriate resources to facilitate successful program completion.

K-12 Students' Perceptions of Scientists: Finding a valid measurement and exploring whether exposure to scientists makes an impact

Science.gov (United States)

Hillman, Susan J.; Bloodsworth, Kylie H.; Tilburg, Charles E.; Zeeman, Stephan I.; List, Henrietta E.

2014-10-01

This study was launched from a National Science Foundation GK-12 grant in which graduate fellows in Science, Technology, Engineering, and Mathematics (STEM) are placed in classrooms to engage K-12 students in STEM activities. The investigation explored whether the STEM Fellows' presence impacted the K-12 students' stereotypical image of a scientist. Since finding a valid instrument is critical, the study involved (1) determining the validity of the commonly administered Draw-A-Scientist Test (DAST) against a newly designed six-question survey and (2) using a combination of both instruments to determine what stereotypes are currently held by children. A pretest-posttest design was used on 485 students, grades 3-11, attending 6 different schools in suburban and rural Maine communities. A significant but low positive correlation was found between the DAST and the survey; therefore, it is imperative that the DAST not be used alone, but corroboration with interviews or survey questions should occur. Pretest results revealed that the children held common stereotypes of scientists, but these stereotypes were neither as extensive nor did they increase with the grade level as past research has indicated, suggesting that a shift has occurred with children having a broader concept of who a scientist can be. Finally, the presence of an STEM Fellow corresponded with decreased stereotypes in middle school and high school, but no change in elementary age children. More research is needed to determine whether this reflects resiliency in elementary children's perceptions or limitations in either drawing or in writing out their responses.

K-12 educators need effective and relevant astronomy professional development. NASA's Mission Science provides innovative and accessible opportunities for K-12 teachers. Science questions involve scale and distance, including Moon/Earth scale, solar system scale, and distance of objects in the universe. Teachers can gain an understanding of basic telescopes, the history of telescopes, ground and satellite based telescopes, and models of JWST Telescope. An in-depth explanation of JWST and Spitzer telescopes gave participants background knowledge for infrared astronomy observations. During teacher training, we taught the electromagnetic spectrum through interactive stations. The stations included an overview via lecture and power point, the use of ultraviolet beads to determine ultraviolet exposure, the study of lenticulars and diagramming of infrared data, looking at visible light through diffraction glasses and diagramming the data, protocols for using astronomy based research in the classroom, and infrared thermometers to compare environmental conditions around the observatory. An overview of LIDAR physics was followed up by a simulated LIDAR mapping of the topography of Mars.We will outline specific steps for K-12 infrared astronomy professional development, provide data demonstrating the impact of the above professional development on educator understanding and classroom use, and detail future plans for additional K-12 professional development.Funding was provided by Washington STEM, NASA, and the Washington Space Grant Consortium.

The Science Education Resource Center (SERC) has created a portal to information for K12 educators to provide high-quality grade level appropriate materials from a wide variety of projects and topics. These materials were compiled across the SERC site, showcasing materials that were created for, or easily adaptable to, K12 classrooms. This resource will help support implementation of Next Generation Science Standards by assisting educators in finding innovative resources to address areas of instruction that are conceptually different than previous national and state science standards. Specifically, the K12 portal assists educators in learning about approaches that address the cross-cutting nature of science concepts, increasing students quantitative reasoning and numeracy skills, incorporating technology such as GIS in the classroom, and by assisting educators of all levels of K12 instruction in using relevant and meaningful ways to teach science concepts. The K12 portal supports educators by providing access to hundreds of teaching activities covering a wide array of science topics and grade levels many of which have been rigorously reviewed for pedagogic quality and scientific accuracy. The portal also provides access to web pages that enhance teaching practices that help increase student's system thinking skills, make lectures interactive, assist instructors in conducting safe and effective indoor and outdoor labs, providing support for teaching energy and climate literacy principles, assisting educators in addressing controversial content, provide guidance in engaging students affective domain, and provides a collection of tools for making teaching relevant in 21st century classrooms including using GIS, Google Earth, videos, visualizations and simulations to model and describe scientific concepts.

Scientists Involved in K-12 Education

Robigou, V.

2004-12-01

The publication of countless reports documenting the dismal state of science education in the 1980s, and the Third International Mathematics and Science Study (TIMMS) report (1996) called for a wider involvement of the scientific community in K-12 education and outreach. Improving science education will not happen without the collaboration of educators and scientists working in a coordinated manner and it requires a long-term, continuous effort. To contribute effectively to K-12 education all scientists should refer to the National Science Education Standards, a set of policies that guide the development of curriculum and assessment. Ocean scientists can also specifically refer to the COSEE recommendations (www.cosee.org) that led to the creation of seven regional Centers for Ocean Sciences Education Excellence. Scientists can get involved in K-12 education in a multitude of ways. They should select projects that will accommodate time away from their research and teaching obligations, their talent, and their interest but also contribute to the education reform. A few examples of effective involvement are: 1) collaborating with colleagues in a school of education that can lead to better education of all students and future teachers, 2) acting as a resource for a national program or a local science fair, 3) serving on the advisory board of a program that develops educational material, 4) speaking out at professional meetings about the value of scientists' involvement in education, 5) speaking enthusiastically about the teaching profession. Improving science education in addition to research can seem a large, overwhelming task for scientists. As a result, focusing on projects that will fit the scientist's needs as well as benefit the science reform is of prime importance. It takes an enormous amount of work and financial and personnel resources to start a new program with measurable impact on students. So, finding the right opportunity is a priority, and stepping

Vocational training (VT) is a mandatory 12 month period for UK dental graduates after graduation. Graduates of Irish Dental Schools are eligible to enter the general dental service in Ireland or obtain an NHS performers list number in the UK immediately after qualification. Reports would suggest that some graduates of Irish Dental Schools are choosing to take part in VT in the UK and find the experience beneficial. This study aimed to record the uptake of VT amongst recent graduates from University College Cork and to document their experiences. It was designed to compare the attitudes and experiences of graduates of Irish Dental Schools who undertook VT compared with those who entered the general dental service.

Observation of Λ-hypernuclei in the reaction 12C(π+,K+)/sub Λ/12C

International Nuclear Information System (INIS)

Milner, E.C.

1985-12-01

The observation of Λ-hypernuclear levels in /sub Λ/ 12 C by associated production through the (π + ,K + ) reaction is reported. Spectrometers used in the measurements are discussed. The /sub Λ/ 12 C excitation energy spectra were recorded at laboratory scattering angles of 5.6 0 , 10.3 0 , and 15.2 0 . The spectra show two major peaks - one attributed to the ground state, and one about 11 MeV higher in excitation. The peak near 11 MeV excitation energy is believed to be almost entirely composed of a multiplet of three J/sup π/ = 2 + states. Relativistic DWBA calculations imply support for the expectation that higher spin states are preferentially populated in the (π + ,K + ) reaction, compared to the (K - ,π - ) reaction in which lower spin states are excited. 29 refs., 40 figs

The elastic scattering of negative K-mesons on the proton and on the neutron of the deuterium has been measured at six incident momenta equally spaced between 1.2 and 2.2 GeV/c. Differential cross sections over the almost complete angular range have been obtained for K/sup - /p and K/sup -/n. The aim of the experiment was the measurement of the pure isospin I=1 reaction K/sup -/n to K/sup -/n. The results for the reaction on proton are a by-product and provide a verification of the assumptions necessary for the analysis of the neutron reaction.

Lon gene and photoprotection in Escherichia coli K-12

Energy Technology Data Exchange (ETDEWEB)

Waksman, G.; Thomas, G.; Favre, A. (Institut de Recherche en Biologie Moleculaire, Group de Photobiologie Moleculaire, Paris (France))

1984-03-01

Photoprotection, i.e. the increased resistance of the cells preilluminated with near ultraviolet light (300-380 nm) to the lethal action of 254nm radiations requires either an integrated prophage or a recA mutation in Escherichia coli K12 strains. Significant photoprotection occurs in an Escherichia coli K12 recA/sup +/ cell containing the lon allele responsible for filamentous growth after 254nm irradiation. The Fil phenotype can be suppressed by the sfiA or sfiB suppressor genes. Since the E. coli K12 recA/sup +/ lon sfiB strain exhibits no more photoprotection, it is concluded that in lon strains photoprotection is due to the abolition of the 254nm induced filamentation by the near ultraviolet treatment. In addition, near ultraviolet illumination of the cells leads to a severe restriction of the bulk protein synthesis. This effect is observed only in nuv/sup +/ cells that contain 4-thiouridine the chromophore responsible for photoprotection. It is proposed that in lon (lysogenic strains) photoprotection is due to prevention of the SOS response. During the growth lag, the low residual level of protein synthesis does not allow the induction of the SOS response and accordingly prevents filamentation (the lytic cycle).

Ras gene plays an important role in the extra- and intra-cellular signal transduction pathway. It mediates series cascade reactions, and eventually actives transcriptional factors in nucleus. It is unknown on the mechanism of carcinogenesis of Ras gene in endometrial carcinoma, though K-ras mutant is very common in endometrial atypical hyperplasia and carcinoma. On basis of discovering the mutation in 12th codon of K-ras in endometrial carcinoma cell line, HEC-1A, we explored the carcinogenesis and molecular mechanism of mutant-type [12Asp] K-ras4B gene. (1) Full-length [12Asp]K-ras4B cDNA was amplified with RT-PCR, then inserted into pcDI eukaryotic expressive vector. (2) Morphological change, growth kinetics in vitro and tumorigencity in nude mice in vivo after-before transfection were observed. (3) To test the cell growth kinetics by methyl thiazolium tetrazolium (MTT) and [3H]thymidine incorporation method. (1) The authors have successfully constructed eukaryotic expression plasmid pcDI-[12Asp] K-ras4B; (2) To confirm that [12Asp] K-ras4B mutant can trigger the neoplastic transformation of NIH3T3 cells by test in vitro and in vivo. (3) After pMCV-RasN17 plasmid, a Ras mutant were transfected into pcDI-[12Asp] K-ras4B cells, the growth of this cell were restrained significantly in comparison with control group. (4) These findings indicate the expression of RafS621A resulted in remarkable inhibition in proliferation of pcDI-[12Asp]K-ras4B cell (P ras4B cell growth (P ras4B gene alone is able to cause neoplastic transformation in NIH3T3 cells in vitro and in vivo.

A review of Computer Science resources for learning and teaching with K-12 computing curricula: an Australian case study

Science.gov (United States)

Falkner, Katrina; Vivian, Rebecca

2015-10-01

To support teachers to implement Computer Science curricula into classrooms from the very first year of school, teachers, schools and organisations seek quality curriculum resources to support implementation and teacher professional development. Until now, many Computer Science resources and outreach initiatives have targeted K-12 school-age children, with the intention to engage children and increase interest, rather than to formally teach concepts and skills. What is the educational quality of existing Computer Science resources and to what extent are they suitable for classroom learning and teaching? In this paper, an assessment framework is presented to evaluate the quality of online Computer Science resources. Further, a semi-systematic review of available online Computer Science resources was conducted to evaluate resources available for classroom learning and teaching and to identify gaps in resource availability, using the Australian curriculum as a case study analysis. The findings reveal a predominance of quality resources, however, a number of critical gaps were identified. This paper provides recommendations and guidance for the development of new and supplementary resources and future research.

2003-12-01

The SOFIA and SIRTF EPO Programs have partnered with the Conceptual Astronomy and Physics Education Research (CAPER) Team in designing, evaluating, and facilitating an online program for K-12 teachers to experience multiwavelength astronomy. An aggressive approach to online course design and delivery has resulted in a highly successful learning experience for teacher-participants. Important aspects of the Invisible Universe Online will eventually be used as a part of SOFIA's Airborne Ambassadors Program for pre-flight training of educators. The Invisible Universe Online is delivered via WebCT through the Montana State University National Teacher Enhancement Network (http://btc.montana.edu/). Currently in its fourth semester, the course has served 115 K-12 teachers. This distance learning online class presents our search for astronomical origins and provides an enhanced understanding of how astronomers use all energies of light to unfold the secrets of the universe. We cover the long chain of events from the birth of the universe through the formation of galaxies, stars, and planets by focusing on the scientific questions, technological challenges, and space missions pursuing this search for origins. Through textbook and internet readings, inquiry exploration with interactive java applets, and asynchronous discussions, we help our students achieve the following course goals: develop scientific background knowledge of astronomical objects and phenomena at multiple wavelengths; understand contemporary scientific research questions related to how galaxies formed in the early universe and how stars and planetary systems form and evolve; describe strategies and technologies for using non-visible wavelengths of EM radiation to study various phenomena; and integrate related issues of astronomical science and technology into K-12 classrooms. This course is being developed, evaluated, and offered through the support of SOFIA and SIRTF EPO Programs, two NASA infrared missions

GABAB receptor phosphorylation regulates KCTD12-induced K+ current desensitization

DEFF Research Database (Denmark)

Adelfinger, L; Turecek, R; Ivankova, K

2014-01-01

released from the G-protein. Receptor-activated K+ currents desensitize in the sustained presence of agonist to avoid excessive effects on neuronal activity. Desensitization of K+ currents integrates distinct mechanistic underpinnings. GABAB receptor activity reduces protein kinase-A activity, which...... reduces phosphorylation of serine-892 in GABAB2 and promotes receptor degradation. This form of desensitization operates on the time scale of several minutes to hours. A faster form of desensitization is induced by the auxiliary subunit KCTD12, which interferes with channel activation by binding to the G......-protein βγ subunits. Here we show that the two mechanisms of desensitization influence each other. Serine-892 phosphorylation in heterologous cells rearranges KCTD12 at the receptor and slows KCTD12-induced desensitization. Likewise, protein kinase-A activation in hippocampal neurons slows fast...

Williamson, Kathryn; McKenzie, D.; Des Jardins, A.; Key, J.; Kanode, C.; Willoughby, S.

2012-05-01

Piloted during the 2011-2012 academic year, the NASA Education Activity Training (NEAT) teacher workshop program has introduced five solar astronomy and space weather activities to over forty Montana K-12 teachers. Because many Montana schools are geographically isolated (40% of Montana students live more than 50 miles from a city) and/or serve traditionally underrepresented groups (primarily Native Americans), professional development for teachers can be costly and time consuming. However, with funding shared by the Atmospheric Imaging Assembly EPO team and the Montana Space Grant Consortium, graduate student specialists are able to host the two-hour NEAT workshops on-site at the schools free of charge, and participating teachers earn two continuing education credits. Leveraging the existing catalogue of research-based NASA activities, the featured NEAT activities were chosen for their ease-of-use and applicability to Montana science standards. These include three advanced activities for older students, such as a paper plate activity for the June 5th, 2012 Transit of Venus, Kinesthetic Astronomy, and the Herschel Infrared experiment, along with two simpler activities for the younger students, such as Solar Cookies and the Electromagnetic War card game. Feedback surveys show that NEAT workshop participants were interested and engaged in the activities and planned on using the activities in their classrooms. With such positive responses, the NEAT program has been a huge success and can serve as a model for other institutions looking to increase their space public outreach and education.

Role of Public Outreach in the University Science Mission: Publishing K-12 Curriculum, Organizing Tours, and Other Methods of Engagement

Science.gov (United States)

Dittrich, T. M.

2015-12-01

Much attention has been devoted in recent years to the importance of Science, Technology, Engineering, and Math (STEM) education in K-12 curriculum for developing a capable workforce. Equally important is the role of the voting public in understanding STEM-related issues that impact public policy debates such as the potential impacts of climate change, hydraulic fracturing in oil and gas exploration, mining impacts on water quality, and science funding. Since voted officials have a major impact on the future of these policies, it is imperative that the general public have an understanding of the basic science behind these issues. By engaging with the public in a more fundamental way, university students can play an important role in educating the public while at the same time enhancing their communication skills and gaining valuable teaching experience. I will talk about my own experiences in (1) evaluating and publishing water chemistry and hazardous waste cleanup curriculum on the K-12 engineering platform TeachEngineering.org, (2) organizing public tours of water and energy sites (e.g., abandoned mine sites, coal power plants, wastewater treatment plants, hazardous waste treatment facilities), and (3) other outreach and communication activities including public education of environmental issues through consultations with customers of a landscaping/lawn mowing company. The main focus of this presentation will be the role that graduate students can play in engaging and educating their local community and lessons learned from community projects (Dittrich, 2014; 2012; 2011).

Effects of paraquat on Escherichia coli: Differences between B and K-12 strains

International Nuclear Information System (INIS)

Kitzler, J.W.; Minakami, H.; Fridovich, I.

1990-01-01

Escherichia coli B and K-12 are equally susceptible to the bacteriostatic effects of aerobic paraquat, but they differed strikingly when the lethality of paraquat was evaluated. E. coli B suffered an apparent loss of viability when briefly exposed to paraquat, whereas E. coli K-12 did not. This difference depended on the ability of the B-strain, but not the K-12 strain, to retain internalized paraquat; the B strain was killed on aerobic tryptic soy-yeast extract plates during the incubation which preceded the counting of colonies. This difference in retention of paraquat between strains was demonstrated by delayed loss of viability, by growth inhibition, and by cyanide-resistant respiration after brief exposure to paraquat, washing, and testing in fresh medium. This difference was also shown by using [ 14 C]paraquat. This previously unrecognized difference between E. coli B and K-12 has been the cause of apparently contradictory reports and should lead to some reevaluation of the pertinent literature

Engineering design skills coverage in K-12 engineering program curriculum materials in the USA

Science.gov (United States)

Chabalengula, Vivien M.; Mumba, Frackson

2017-11-01

The current K-12 Science Education framework and Next Generation Science Standards (NGSS) in the United States emphasise the integration of engineering design in science instruction to promote scientific literacy and engineering design skills among students. As such, many engineering education programmes have developed curriculum materials that are being used in K-12 settings. However, little is known about the nature and extent to which engineering design skills outlined in NGSS are addressed in these K-12 engineering education programme curriculum materials. We analysed nine K-12 engineering education programmes for the nature and extent of engineering design skills coverage. Results show that developing possible solutions and actual designing of prototypes were the highly covered engineering design skills; specification of clear goals, criteria, and constraints received medium coverage; defining and identifying an engineering problem; optimising the design solution; and demonstrating how a prototype works, and making iterations to improve designs were lowly covered. These trends were similar across grade levels and across discipline-specific curriculum materials. These results have implications on engineering design-integrated science teaching and learning in K-12 settings.

Identification of influential spreaders in online social networks using interaction weighted K-core decomposition method

Science.gov (United States)

Al-garadi, Mohammed Ali; Varathan, Kasturi Dewi; Ravana, Sri Devi

2017-02-01

Online social networks (OSNs) have become a vital part of everyday living. OSNs provide researchers and scientists with unique prospects to comprehend individuals on a scale and to analyze human behavioral patterns. Influential spreaders identification is an important subject in understanding the dynamics of information diffusion in OSNs. Targeting these influential spreaders is significant in planning the techniques for accelerating the propagation of information that is useful for various applications, such as viral marketing applications or blocking the diffusion of annoying information (spreading of viruses, rumors, online negative behaviors, and cyberbullying). Existing K-core decomposition methods consider links equally when calculating the influential spreaders for unweighted networks. Alternatively, the proposed link weights are based only on the degree of nodes. Thus, if a node is linked to high-degree nodes, then this node will receive high weight and is treated as an important node. Conversely, the degree of nodes in OSN context does not always provide accurate influence of users. In the present study, we improve the K-core method for OSNs by proposing a novel link-weighting method based on the interaction among users. The proposed method is based on the observation that the interaction of users is a significant factor in quantifying the spreading capability of user in OSNs. The tracking of diffusion links in the real spreading dynamics of information verifies the effectiveness of our proposed method for identifying influential spreaders in OSNs as compared with degree centrality, PageRank, and original K-core.

A Graduate Student's Experience and Perspective on a Student-Teacher-Researcher Partnership

Science.gov (United States)

Bostic, J.; Stylinski, C.; Doty, C.

2017-12-01

Teachers and their K-12 students lack firsthand experience in science research and often harbor misconceptions about science practices and the nature of science. To address this challenge, the NOAA-funded Student-Teacher-Researcher (STAR) partnership that provides rural high school students with authentic research experiences investigating the amount and sources of nitrate in schoolyard runoff. Teachers received training, guiding curricular materials aligned with NGSS and in-classroom support. With a focus on evidence-based reasoning skills, students actively participate in the research process through sample collection, data analysis, and an in-person discussion of conclusions and implications with our scientist team. As a member of this team, I assisted with refining the study design, analyzing nitrate isotope runoff samples, and sharing insights and feedback with students during the in-person discussion session. Assessment results indicate student gained an understanding of nitrate pollution and of science practices. As a graduate student, young scientist, and possessor of a B.S. in Science Education, I already recognized the value of involving K-12 students and teachers in authentic research experiences, as these experiences expose students to the nature of science while also improving content knowledge. During the STAR partnership, I learned firsthand some of the obstacles presented during outreach involving partnerships between a research institution and schools, such as inflexibility of school scheduling and the need for flexibility with research questions requiring complex lab analysis. Additionally, I discovered the challenge of working systemically across a school district, which can have broad impact but limit student experiences. Highlights of my experience included interactions with students and teachers, especially when students have unexpected answers to my questions, providing novel explanations for patterns observed in the data.

Graphical abstract: - Highlights: • Encapsulation of Li, Na and K narrow the HOMO–LUMO gaps of the clusters. • The group III nitrides nanoclusters strongly interacted with the alkali metals. • First hyperpolarizabilities remarkably enhance for B{sub 12}N{sub 12} encapsulated with Na/K. - Abstract: Density functional theory (DFT) calculations have been carried out to study the influence of alkali metals (Li, Na and K) encapsulation within the group III nitrides (B{sub 12}N{sub 12}, Al{sub 12}N{sub 12} and Ga{sub 12}N{sub 12}) and the group IV carbides (C{sub 24}, Si{sub 12}C{sub 12}and Ge{sub 12}C{sub 12}) nanoclusters. The encapsulation of Li, Na and K atoms is found to narrow the HOMO–LUMO gaps of the considered clusters. The electronic properties of these clusters, especially the group III nitrides nanoclusters, are strongly sensitive to interaction with the alkali metals. Moreover it is observed that the encapsulation of alkali metals enhances the first hyperpolarizabilities of B{sub 12}N{sub 12} nanocluster. Surprisingly, due to the alkali metals encapsulation within B{sub 12}N{sub 12} nanocluster, the first hyperpolarizability values are remarkably increased to 8505.49 and 122,503.76 a.u. for Na@B{sub 12}N{sub 12} and K@B{sub 12}N{sub 12}, respectively. Also the TD-DFT calculations at both CAM-B3LYP/6-311+G(d) and PBE0/6-311+G(d) levels of theory are also performed to investigate the origin of first hyperpolarizabilities.

Success Stories of Undergraduate Retention: A Pathways Study of Graduate Students in Solar and Space Physics

Science.gov (United States)

Morrow, C. A.; Stoll, W.; Moldwin, M.; Gross, N. A.

2012-12-01

This presentation describes results from an NSF-funded study of the pathways students in solar and space physics have taken to arrive in graduate school. Our Pathways study has documented results from structured interviews conducted with graduate students attending two, week-long, NSF-sponsored scientific workshops during the summer of 2011. Our research team interviewed 48 solar and space physics students (29 males and 19 females currently in graduate programs at US institutions,) in small group settings regarding what attracted and retained them along their pathways leading to grad school. This presentation addresses what these students revealed about the attributes and influences that supported completion of their undergraduate experience and focused their aspirations toward graduate school. In advance of the interview process, we collected 125 on-line survey responses from students at the two workshops. This 20-item survey included questions about high school and undergraduate education, as well as about research and graduate experience. A subset of the 125 students who completed this on-line survey volunteered to be interviewed. Two types of interview data were collected from the 48 interviewees: 1) written answers to a pre-interview questionnaire; and 2) detailed notes taken by researchers during group interviews. On the pre-interview questionnaire, we posed the question: "How did you come to be a graduate student in your field?" Our findings to date are based on an analysis of responses to this question, cross correlated with the corresponding on-line survey data. Our analysis reveals the importance of early research experiences. About 80% of the students participating in the Pathways study cited formative undergraduate research experiences. Moreover, about 50% of participants reported undergraduate research experiences that were in the field of their current graduate studies. Graduate students interviewed frequently cited a childhood interest in science

Photoprotection, i.e. the increased resistance of the cells preilluminated with near ultraviolet light (300-380 nm) to the lethal action of 254nm radiations requires either an integrated prophage or a recA mutation in Escherichia coli K12 strains. Significant photoprotection occurs in an Escherichia coli K12 recA + cell containing the lon allele responsible for filamentous growth after 254nm irradiation. The Fil phenotype can be suppressed by the sfiA or sfiB suppressor genes. Since the E. coli K12 recA + lon sfiB strain exhibits no more photoprotection, it is concluded that in lon strains photoprotection is due to the abolition of the 254nm induced filamentation by the near ultraviolet treatment. In addition, near ultraviolet illumination of the cells leads to a severe restriction of the bulk protein synthesis. This effect is observed only in nuv + cells that contain 4-thiouridine the chromophore responsible for photoprotection. It is proposed that in lon (lysogenic strains) photoprotection is due to prevention of the SOS response. During the growth lag, the low residual level of protein synthesis does not allow the induction of the SOS response and accordingly prevents filamentation (the lytic cycle). (author)

The Engaged Microbiologist: Bringing the Microbiological Sciences to the K-12 Community.

Westenberg, David J

2016-03-01

Exposing K-12 students to cutting edge science that impacts their daily lives can bring classroom lessons to life. Citizen-science projects are an excellent way to bring high-level science to the classroom and help satisfy one of the cornerstone concepts of the Next Generation Science Standards (NGSS), "engaging in practices that scientists and engineers actually use." This can be a daunting task for teachers who may lack the background or resources to integrate these projects into the classroom. This is where scientific societies such as the American Society for Microbiology (ASM) can play a critical role. ASM encourages its members to engage with the K-12 community by providing networking opportunities and resources for ASM members and K-12 teachers to work together to bring microbiology into the classroom.

CP violation and ΔI=1/2 enhancement in K decays

Choudhury, S.R.; Scadron, M.D.

1996-01-01

We study CP-conserving and CP-violating K 0 →ππ and K 0 →ππγ decays, using the same techniques which explain the ΔI=1/2 enhancement of the former to also explore CP violation of the latter transitions. If CP violation is driven by the WWγ vertex, we show that direct CP violation in K L →ππγ is scaled to the s→dγ E1 quark transition and the latter is suppressed by the GIM mechanism (compatible with recent experiments). In the same spirit, the dominant ΔI=1/2 enhancement of CP-conserving kaon weak decays can be scaled to an s→d quark transition which is enhanced by the GIM mechanism. copyright 1996 The American Physical Society

The influence of excess K2O on the electrical properties of (K,Na)1/2Bi1/2TiO3 ceramics

Science.gov (United States)

Li, Linhao; Li, Ming; Sinclair, Derek C.

2018-04-01

The solid solution (KxNa0.50-x)Bi0.50TiO3 (KNBT) between Na1/2Bi1/2TiO3 and K1/2Bi1/2TiO3 (KBT) has been extensively researched as a candidate lead-free piezoelectric material because of its relatively high Curie temperature and good piezoelectric properties, especially near the morphotropic phase boundary (MPB) at x ˜ 0.10 (20 mol. % KBT). Here, we show that low levels of excess K2O in the starting compositions, i.e., (Ky+0.03Na0.50-y)Bi0.50TiO3.015 (y-series), can significantly change the conduction mechanism and electrical properties compared to a nominally stoichiometric KNBT series (KxNa0.50-x)Bi0.50TiO3 (x-series). Impedance spectroscopy measurements reveal significantly higher bulk conductivity (σb) values for y ≥ 0.10 samples [activation energy (Ea) ≤ 0.95 eV] compared to the corresponding x-series samples which possess bandgap type electronic conduction (Ea ˜ 1.26-1.85 eV). The largest difference in electrical properties occurs close to the MPB composition (20 mol. % KBT) where y = 0.10 ceramics possess σb (at 300 °C) that is 4 orders of magnitude higher than that of x = 0.10 and the oxide-ion transport number in the former is ˜0.70-0.75 compared to processing. This demonstrates the electrical properties of KNBT to be sensitive to low levels of A-site nonstoichiometry and indicates that excess K2O in KNBT starting compositions to compensate for volatilisation can lead to undesirable high dielectric loss and leakage currents at elevated temperatures.

Overexpression of heterogeneous nuclear ribonucleoprotein K (hnRNP K), a DNA/RNA binding protein, is associated with metastasis in nasopharyngeal carcinoma (NPC). However, the mechanisms underlying hnRNP K-mediated metastasis is unclear. The aim of the present study was to determine the role of matrix metalloproteinase (MMP) in hnRNP K-mediated metastasis in NPC. We studied hnRNP K-regulated MMPs by analyzing the expression profiles of MMP family genes in NPC tissues and hnRNP K-knockdown NPC cells using Affymetrix microarray analysis and quantitative RT-PCR. The association of hnRNP K and MMP12 expression in 82 clinically proven NPC cases was determined by immunohistochemical analysis. The hnRNP K-mediated MMP12 regulation was determined by zymography and Western blot, as well as by promoter, DNA pull-down and chromatin immunoprecipitation (ChIP) assays. The functional role of MMP12 in cell migration and invasion was demonstrated by MMP12-knockdown and the treatment of MMP12-specific inhibitor, PF-356231. MMP12 was overexpressed in NPC tissues, and this high level of expression was significantly correlated with high-level expression of hnRNP K (P = 0.026). The levels of mRNA, protein and enzyme activity of MMP12 were reduced in hnRNP K-knockdown NPC cells. HnRNP K interacting with the region spanning −42 to −33 bp of the transcription start site triggered transcriptional activation of the MMP12 promoter. Furthermore, inhibiting MMP12 by MMP12 knockdown and MMP12-specific inhibitor, PF-356231, significantly reduced the migration and invasion of NPC cells. Overexpression of MMP12 was significantly correlated with hnRNP K in NPC tissues. HnRNP K can induce MMP12 expression and enzyme activity through activating MMP12 promoter, which promotes cell migration and invasion in NPC cells. In vitro experiments suggest that NPC metastasis with high MMP12 expression may be treated with PF-356231. HnRNP K and MMP12 may be potential therapeutic markers for NPC, but

The Delicate Balance between Research, Teaching and Outreach: A Case Study of Physicists in K-12 Education

2003-04-01

Recent calls from a variety of sectors including some funding agencies and professional societies encourage physicists to take a more active interest in the education of K-12 students and their teachers. Although there are a broad range of possible activities, finding time to participate is always a challenge for the researcher. How does the busy physicist ensure that the time devoted to education or outreach activities produces meaningful results without adversely affecting his or her research program? Project Fulcrum, a NSF-funded program that teams science and math graduate students at the University of Nebraska-Lincoln with 4th -8th grade teachers in the Lincoln Public Schools, presents a case study of how research scientists can be meaningfully involved with K-12 education. Project Fulcrum's preliminary results indicate that the impact scientists have in the classroom goes far beyond providing expertise in physics, and turns out to be very different than originally anticipated. There are a wide variety of models for involvement in education and outreach that cover a broad span of time and energy commitments. Careful project choice, establishing administrative infrastructure, collaborating with other departments and colleges, and involving colleagues can optimize the impact-made-to-time-spent ratio. Challenges such as project evaluation, overcoming the negative attitudes of some physicists towards anything not related to research, and ensuring that participants get appropriate credit for their efforts will also be discussed. The conclusion will address the personal and professional rewards of involvement in education and outreach. This work is funded by the National Science Foundation (NSF-DGE0086358). The author wishes to acknowledge the contributions of co-PIs G. Buck, S. Kirby, R. Kirby and P. Dussault, and all of the Project Fulcrum Fellows and Teachers.

Full Text Available The purpose of this case study was to investigate online discussion as a means to promote critical reflection. The study was conducted during a semester-long graduate course on issues related to literacy instructional strategies. The participants in the study were four reading education candidates. During the semester they participated in online discussion about course readings and reflected on their own teaching experiences. The data sources were the online discussion postings, responses to questionnaires, and interviews. The results suggest that technology-mediated discussion strengthens the learning community, facilitates sharing of professional experience among participants, and enhances teacher reflection. The results also point to the multi-faceted nature of teacher reflection.

Neutron inelastic sattering from liquid 3He at 40 mK and at 1.2 K

International Nuclear Information System (INIS)

Skoeld, K.; Pelizzari, C.A.

1978-01-01

In a previous neutron scattering experiment on 3 He at T = 15 mK the present authors observed two peaks in the scattering function which were identified as the zero sound mode and the spin-fluctuation peak respectively. These results are different from those obtained by others at T = 0.63 K in which case no such structure was observed. In order to determine whether this discrepancy is due to the difference in the temperature of the two experiments, measurements have now been made at T = 40 mK and at T = 1.2 K. These results show that the two-peak structure persists at the higher temperature although measurable broadening is observed in the spin-fluctuation part of the spectrum. (author)

Perceptions of preparedness of LBS I teachers in the state of Illinois and graduates of Illinois State University's LBS I program to collaborate in teaching grade 7--12 math, science, and social science

Science.gov (United States)

Caldwell, Janet E.

The expectations for no child to be left behind are leading to increased emphasis on teaching math, science, and social science effectively to students with disabilities. This study utilized information collected from online surveys to examine how current LBS I teachers and individuals graduating from the Illinois State University teacher certification program in LBS I perceive their preparedness to teach these subjects. Participants provided information about coursework and life experiences, and they made suggestions about teacher preparation and professional development programs. Six key items forming the composite variable focused on level of preparation in (a) best practices, (b) selecting materials, (c) selecting objectives, (d) adapting instructional strategies, (e) planning lessons, and (f) and evaluating outcomes. Only 30 LBS I teachers of the 282 contacted by e-mail completed surveys. Of 115 graduates contacted, 71 participated in the original survey and 23 participated in a follow-up survey. Data were analyzed to learn more about the teachers' self-perceptions regarding preparedness to teach math, science, or social science. There was a correlation between perceived level of knowledge and the composite preparation variable for all subjects, but no correlation with length of teaching. Both groups indicated high school content courses were important in preparation to teach. Teachers also indicated collaboration and graduates indicated grade school learning. The most frequent recommendation for both teacher preparation and professional development was additional methods courses. A survey distributed to math, science, and social science teachers of Grades 7--12 asked about their perceptions of the preparedness of LBS I teachers to teach their area of content. Few surveys were completed for each subject so they were examined qualitatively. There was variability among participants, but generally the content area teachers rated themselves as more prepared than

Unprofessional content on Facebook accounts of US urology residency graduates.

2017-06-01

To characterize unprofessional content on public Facebook accounts of contemporary US urology residency graduates. Facebook was queried with the names of all urologists who graduated from US urology residency programmes in 2015 to identify publicly accessible profiles. Profiles were assessed for unprofessional or potentially objectionable content using a prospectively designed rubric, based on professionalism guidelines by the American Urological Association, the American Medical Association, and the Accreditation Council for Graduate Medical Education. Content authorship (self vs other) was determined, and profiles were reviewed for self-identification as a urologist. Of 281 graduates, 223 (79%) were men and 267 (95%) held MD degrees. A total of 201 graduates (72%) had publicly identifiable Facebook profiles. Of these, 80 profiles (40%) included unprofessional or potentially objectionable content, including 27 profiles (13%) reflecting explicitly unprofessional behaviour, such as depictions of intoxication, uncensored profanity, unlawful behaviour, and confidential patient information. When unprofessional content was found, the content was self-authored in 82% of categories. Among 85 graduates (42%) who self-identified as a urologist on social media, nearly half contained concerning content. No differences in content were found between men and women, MD and DO degree-holders, or those who did or did not identify as a urologist (all P > 0.05). The majority of recent residency graduates had publicly accessible Facebook profiles, and a substantial proportion contained self-authored unprofessional content. Of those identifying as urologists on Facebook, approximately half violated published professionalism guidelines. Greater awareness of trainees' online identities is needed. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

Full Text Available The need for hands-on computer laboratory experience in undergraduate and graduate statistics education has been firmly established in the past decade. As a result a number of attempts have been undertaken to develop novel approaches for problem-driven statistical thinking, data analysis and result interpretation. In this paper we describe an integrated educational web-based framework for: interactive distribution modeling, virtual online probability experimentation, statistical data analysis, visualization and integration. Following years of experience in statistical teaching at all college levels using established licensed statistical software packages, like STATA, S-PLUS, R, SPSS, SAS, Systat, etc., we have attempted to engineer a new statistics education environment, the Statistics Online Computational Resource (SOCR. This resource performs many of the standard types of statistical analysis, much like other classical tools. In addition, it is designed in a plug-in object-oriented architecture and is completely platform independent, web-based, interactive, extensible and secure. Over the past 4 years we have tested, fine-tuned and reanalyzed the SOCR framework in many of our undergraduate and graduate probability and statistics courses and have evidence that SOCR resources build student's intuition and enhance their learning.

The structure of hexadeca-mu-acetato-tetraaquadodeca-mu(3)-oxo-dodecamanganese bis(acetic acid) tetrahydrate, [Mn(12)O(12)(CH(3)COO)(16)(H(2)O)(4)] x 2CH(3)COOH x 4H(2)O, known as Mn(12)-acetate, has been determined at 83 (2) K by X-ray diffraction methods. The fourfold (S(4)) molecular symmetry is disrupted by a strong hydrogen-bonding interaction with the disordered acetic acid molecule of solvation, which displaces one of the acetate ligands in the cluster. Up to six Mn(12) isomers are potentially present in the crystal lattice, which differ in the number and arrangement of hydrogen-bonded acetic acid molecules. These results considerably improve the structural information available on this molecular nanomagnet, which was first synthesized and characterized by Lis [Acta Cryst. (1980), B36, 2042-2046].

From student to graduate: longitudinal changes in the qualities of nurses.

To examine the development of perceived qualities of nursing from student to graduate nurse over time. Researchers continue to explore student nurse and new graduate nurse attrition, particularly in the light of a looming crisis in nursing recruitment and retention. Qualities of nurses represent the job fit of nursing from student to graduate years. A prospective longitudinal design with a convenience sample was used for this study. Data were collected annually from 2009-2012 through the completion of a short on-line survey. The sample size of undergraduate nurses in year 1 was 676, with 527 in year 2, 339 in year 3 and 190 in year 4. Only 136 participants completed the survey each year forming the complete data set for analysis. Most qualities of nursing differed significantly across time with the qualities of Caring, Empathetic, Knowledge and Respectful demonstrating strong changes. Most declines in scores occurred on graduation. Caring, the central tenet of nursing increased during the student years and declined slightly on graduation. This unique longitudinal study of Australian nurses suggests that the clinical experience and theoretical grounding provided in our University programs, has resulted in an increasing cumulative effect in the third year supporting most qualities of nurses/nursing understood in year 1, that is, the career fit to perceptions, has been achieved. The decline in the 1(st) year of graduation, where the concept of workplace misfit is occurring, is where further nurse graduate support is urgently required. © 2015 John Wiley & Sons Ltd.

Assessing the impact of a training programme is important for quality assurance and further development. It also can helps with accountability and marketing purposes. This study evaluated the impact of King's College London (KCL) Master of Science programme in Dental Public Health in terms of graduates' perceived learned skills and professional development. An online questionnaire was sent to individuals who completed successfully the KCL Master of Science programme in Dental Public Health and had a valid email address. Participants provided information on demographic characteristics, perceived learned skills (intellectual, practical and generic) and professional development (type of organisation, position in the organisation and functions performed at work before and after the programme). Learned skills' scores were compared by demographic factors in multiple linear regression models, and the distribution of responses on career development was compared using nonparametric tests for paired groups. Although all scores on learned skills were on the favourable side of the Likert scale, graduates reported higher scores for practical skills, followed by intellectual and generic skills. No differences in scores were found by sex, age, nationality or time since graduation. In terms of career development, there were significantly higher proportions of graduates working in higher education institutions and taking leadership/managerial roles in organisations as well as greater number and variety of functions at work after than before the programme. This online survey shows that the programme has had a positive impact on graduates in terms of perceived learned skills and professional development. © 2015 The Authors.

Full Text Available It is one of six modules within the SIF (Strategic Innovative Fund funded Generic Skills Project for PHDS. The Generic Skills Project itself was just one strand within others Supporting the development of 4th level education in Ireland. The Graduate Information Skills module is a collaborative project led by NUI Galway with partners Trinity College Dublin and University College Cork. It is aimed at PHDS but Masters Research and post-docs will find the module of benefit too. The module is developed to offer both an online and face-to-face environment and be customizable with eLearning environments. Project launched in 2007 and has a three year cycle. We agreed to outsource online development and after a tendering process a company called eMedia were awarded the contract. We have piloted full content to PHDS in the three institutions involved and have reviewed feed-back received from attendees. We have also met with module presenters and authors to review their feed-back. The initial content while generic to all PHDS has Science Technology Medicine specific examples. We have complete Online content and module is being offered locally for face-to-face credited teaching. The module has in all units Learning Outcomes and is intended to be fully credited and evaluated for module completion. Funds allowing we would hope to develop Humanities specific content, add units such as on Writing Skills etc. We feel the module has created very good blended learning opportunities and is offered to students in a very contemporary design format. In an Irish context we feel the module offers a national resource that could be used by other institutions.

Glucose and creatinine are two of the most frequently measured substances in human blood/serum for assessing the health status of individuals. Because of their clinical significance, CCQM-K11 glucose in human serum and CCQM-K12 creatinine in human serum were the fourth and fifth key comparisons (KCs) performed by the Organic Analysis Working Group (OAWG). These KCs were conducted in parallel and were completed in 2001. The initial subsequent KCs for glucose, CCQM-K11.1, and creatinine, CCQM-K12.1, were completed in 2005. Measurements for the next KCs for these two measurands, CCQM-K11.2 and CCQM-K12.2, were completed in 2013. While designed as subsequent KCs, systematic discordances between the participants' and the anchor institution's results in both comparisons lead the OAWG to request reference results from two experienced laboratories that had participated in the 2001 comparisons. Based on the totality of the available information, the OAWG converted both CCQM-K11.2 and CCQM-K12.2 to 'Track C' KCs where the key comparison reference value is estimated by consensus. These comparisons highlighted that carrying out comparisons for complex chemical measurements and expecting to be able to treat them under the approaches used for formal CIPM subsequent comparisons is not an appropriate strategy. The approach used here is a compromise to gain the best value from the comparison; it is not an approach that will be used in the future. Instead, the OAWG will focus on Track A and Track C comparisons that are treated as stand-alone entities. Participation in CCQM-K11.2 demonstrates a laboratory's capabilities to measure a polar (pKow > 2), low molecular mass (100 g/mol to 500 g/mol) metabolite in human serum at relatively high concentrations (0.1 mg/g to 10 mg/g). Participation in CCQM-K12.2 demonstrates capabilities to measure similar classes of metabolites at relatively low concentrations (1 μg/g to 30 μg/g). The capabilities required for the analysis of complex

Chen Daolong; Wang Xuan; Li Xinying; Sun Huiqing; Zhu Jie

1998-04-01

The component construction and their performances of the intelligent type sodium level gauge newly-developed and its graduation calibration facility are presented. They can be operated in the temperature limit 100∼550 degree C. Its graduation characteristic calibration test is described. The temperature effect is analyzed. The graduation characteristic equation using the medium temperature as the parameter is given. The calibration errors are analyzed. The measurement system using this sodium level gauge is presented. The tests show that the intelligent type sodium level gauge possesses good linearity. The accurate sodium level measurement data can be obtained by means of its on-line compensation function of the temperature effect. Moreover, it possesses the self-inspection, the electric shutoff protection, the setting of full-scale, the thermocouple breaking alarm, the two upper limits and two lower limits alarms, the standard analog output signal and the digital output signal. Therefore, it is applicable particularly to the instrument, control and protection systems of LMFBR. The basic error of this intelligent type sodium level gauge is +-1.9% of measuring range

Education and Professional Outreach as an Integrated Component of Science and Graduate Education

Science.gov (United States)

Staudigel, H.; Koppers, A. A.

2007-12-01

Education and Professional Outreach (EPO) is increasingly becoming a substantive and much needed activity for scientists. Significant efforts are expended to satisfy funding agency requirements, but such requirements may also develop into a mutually beneficial collaboration between scientists and K-16 educators with a minimal impact on science productivity. We focus here on two particularly high impact EPO opportunities, hosting of high school interns and the inclusion of an educational component to a graduate student's&pthesis work. We emphasize the importance of hands-on collaboration with teachers and teacher-educators, and the substantive benefits of highly leveraged customized internet-distribution. We will present two examples for how we integrated this K-12 EPO into our university-based science and education efforts, what types of products emerged from these activities, and how such products may be widely produced by any scientist and disseminated to the educational community. High school seniors offer a unique resource to university EPO because some of them can substantively contribute to the science, and they can be very effective peer-mentors for high and middle schools. Extended internships may be built easily into the schedule of many senior high school student programs, and we were able to involve such interns into a three-week seagoing expedition. The seniors were responsible for our EPO by maintaining a cruise website and video conferencing with their high school. They added substantially to the science outcome, through programming and participating in a range of shipboard science chores. Graduate theses may be augmented with an educational component that places the main theme of the thesis into an educational setting. We designed and supervised such a Master's graduate thesis with an educational component on the geochronology of hot spot volcanoes, including a high school lesson plan, enactment in the classroom and preparation of a wide range of web

Role of alkali carbonate and salt in topochemical synthesis of K1/2Na1/2NbO3 and NaNbO3 templates

Science.gov (United States)

Lee, Jae-Seok; Jeon, Jae-Ho; Choi, Si-Young

2013-11-01

Since the properties of lead-free piezoelectric materials have thus far failed to meet those of lead-based materials, either chemical doping or morphological texturing should be employed to improve the piezoelectric properties of lead-free piezoelectric ceramics. The goal of this study was to synthesize plate-like K1/2Na1/2NbO3 and NaNbO3 particles, which are the most favorable templates for morphological texturing of K1/2Na1/2NbO3 ceramics. To achieve this goal, Bi2.5Na3.5Nb5O18 precursors in a plate-like shape were first synthesized and subsequently converted into K1/2Na1/2NbO3 or NaNbO3 particles that retain the morphology of Bi2.5Na3.5Nb5O18. In this study, we found that sodium or potassium carbonate does not play a major role in converting the Bi2.5Na3.5Nb5O18 precursor to K1/2Na1/2NbO3 or NaNbO3, on the contrary to previous reports; however, the salt contributes to the conversion reaction. All synthesis processes have been performed via a molten salt method, and scanning electron microscopy, scanning probe microscopy, and inductively coupled plasma mass spectroscopy were used to characterize the synthesized K1/2Na1/2NbO3 or NaNbO3 templates.

Mayer, A. S.; Vye, E.

2016-12-01

The Michigan Tech GlobalWatershed GK-12 Fellowship program bridges the gap between K-12 learning institutions and the scientific community with a focus on watershed research. Michigan Tech graduate students (fellows) work in tandem with teachers on the development of relevant hands-on, inquiry based lesson plans and activities based on their doctoral research projects in watershed science. By connecting students and teachers to state of the art academic research in watershed science, teachers are afforded a meaningful way in which to embed scientific research as a component of K-12 curricula, while mentoring fellows on the most pertinent and essential topics for lesson plan development. Fellows fulfill their vital responsibility of communicating their academic research to a broader public while fostering improved teaching and communication skills. A goal of the project is to increase science literacy among students so they may understand, communicate and participate in decisions made at local, regional, and global levels. The project largely works with schools located in Michigan's western Upper Peninsula but also partners with K-12 systems in Sonora, Mexico. While focusing on local and regional issues, the international element of the project helps expand student, teacher, and fellow worldviews and global awareness of watershed issues and creates meaningful partnerships. Lesson plans are available online and teacher workshops are held regularly to disseminate the wealth of information and resources available to the broader public. Evaluation results indicate that fellows' skill and confidence in their ability to communicate science increased as a results of their participation of the program, as well as their desire to communicate science in their future careers. Teachers' confidence in their capacity to present watershed science to their students increased, along with their understanding of how scientific research contributes to understanding of water

Health literacy and the Internet: a study on the readability of Australian online health information.

Science.gov (United States)

Cheng, Christina; Dunn, Matthew

2015-08-01

Almost 80% of Australian Internet users seek out health information online so the readability of this information is important. This study aimed to evaluate the readability of Australian online health information and determine if it matches the average reading level of Australians. Two hundred and fifty-one web pages with information on 12 common health conditions were identified across sectors. Readability was assessed by the Flesch-Kincaid (F-K), Simple Measure of Gobbledygook (SMOG) and Flesch Reading Ease (FRE) formulas, with grade 8 adopted as the average Australian reading level. The average reading grade measured by F-K and SMOG was 10.54 and 12.12 respectively. The mean FRE was 47.54, a 'difficult-to-read' score. Only 0.4% of web pages were written at or below grade 8 according to SMOG. Information on dementia was the most difficult to read overall, while obesity was the most difficult among government websites. The findings suggest that the readability of Australian health websites is above the average Australian levels of reading. A quantifiable guideline is needed to ensure online health information accommodates the reading needs of the general public to effectively use the Internet as an enabler of health literacy. © 2015 Public Health Association of Australia.

Miller, Casey W.; Belyea, Dustin; Chabot, Michelle; Messina, Troy

2012-02-01

A method is described to empower students to efficiently perform general and specific literature searches using online resources [Miller et al., Am. J. Phys. 77, 1112 (2009)]. The method was tested on multiple groups, including undergraduate and graduate students with varying backgrounds in scientific literature searches. Students involved in this study showed marked improvement in their awareness of how and where to find scientific information. Repeated exposure to literature searching methods appears worthwhile, starting early in the undergraduate career, and even in graduate school orientation.

Infrared Astronomy Professional Development for K-12 Educators: WISE Telescope

Science.gov (United States)

Borders, Kareen; Mendez, B. M.

2010-01-01

K-12 educators need effective and relevant astronomy professional development. WISE Telescope (Wide-Field Infrared Survey Explorer) and Spitzer Space Telescope Education programs provided an immersive teacher professional development workshop at Arecibo Observatory in Puerto Rico during the summer of 2009. As many common misconceptions involve scale and distance, teachers worked with Moon/Earth scale, solar system scale, and distance of objects in the universe. Teachers built and used basic telescopes, learned about the history of telescopes, explored ground and satellite based telescopes, and explored and worked on models of WISE Telescope. An in-depth explanation of WISE and Spitzer telescopes gave participants background knowledge for infrared astronomy observations. We taught the electromagnetic spectrum through interactive stations. The stations included an overview via lecture and power point, the use of ultraviolet beads to determine ultraviolet exposure, the study of WISE lenticulars and diagramming of infrared data, listening to light by using speakers hooked up to photoreceptor cells, looking at visible light through diffraction glasses and diagramming the data, protocols for using astronomy based research in the classroom, and infrared thermometers to compare environmental conditions around the observatory. An overview of LIDAR physics was followed up by a simulated LIDAR mapping of the topography of Mars. We will outline specific steps for K-12 infrared astronomy professional development, provide data demonstrating the impact of the above professional development on educator understanding and classroom use, and detail future plans for additional K-12 professional development. Funding was provided by WISE Telescope, Spitzer Space Telescope, Starbucks, Arecibo Observatory, the American Institute of Aeronautics and Astronautics, and the Washington Space Grant Consortium.

Garcia-Williams, Amanda G; Moffitt, Lauren; Kaslow, Nadine J

2014-10-01

The objective of this paper is to describe the mental health and service utilization of graduate students at a large southeastern university and identify psychological factors associated with their student suicidal behavior. E-mail invitations to complete the Interactive Screening Program, an online anonymous mental health questionnaire, were sent to graduate students. The questionnaire included the Patient Health Questionnaire (PHQ-9) as well as items assessing suicide behavior, anxiety, negative emotion, substance use, eating behavior, and service utilization. A total of 301 graduate students responded to the questionnaires between 14 July 2010 and 24 January 2012. With regards to suicide, 7.3 % of the sample reported thoughts of suicide, 2.3 % reported having plans for suicide, and 1.7 % had hurt themselves in the past 2 weeks; while 9.9 % had ever made a suicide attempt in their lifetime. Graduate students had PHQ-9 scores indicating mild depression, and more than half endorsed feeling nervous, irritable, stressed, anxious, lonely, or having fights/arguments. In terms of service utilization, 22.2 % of the sample was currently taking some type of medication, and 18.5 % currently in counseling/therapy are females and those with higher PHQ-9 scores more likely to be using services. Those endorsing suicidal behavior in the past 2 weeks had significantly higher depression scores than those without such behavior and were characterized by more anxiety, negative emotions (such as loneliness, anger, hopelessness, desperation, and being out of control), substance use, and eating problems. Graduate students experience significant amounts of stress and anxiety, and their suicidal behavior is strongly characterized by depression, hopelessness, desperation, lack of control, and eating problems. Future work with this population should focus on the development and evaluation of mental health and wellness interventions and on ways to promote help-seeking, especially among male

Spence, Anne

2013-03-01

Engineers rely on physicists as well as other scientists and mathematicians to explain the world in which we live. Engineers take this knowledge of the world and use it to create the world that never was. The teaching of physics and other sciences as well as mathematics is critical to maintaining our national workforce. Science and mathematics education are inherently different, however, from engineering education. Engineering educators seek to enable students to develop the habits of mind critical for innovation. Through understanding of the engineering design process and how it differs from the scientific method, students can apply problem and project based learning to solve the challenges facing society today. In this talk, I will discuss the elements critical to a solid K-12 engineering education that integrates science and mathematics to solve challenges throughout the world.

1985-12-01

The observation of ..lambda..-hypernuclear levels in /sub ..lambda..//sup 12/C by associated production through the (..pi../sup +/,K/sup +/) reaction is reported. Spectrometers used in the measurements are discussed. The /sub ..lambda..//sup 12/C excitation energy spectra were recorded at laboratory scattering angles of 5.6/sup 0/, 10.3/sup 0/, and 15.2/sup 0/. The spectra show two major peaks - one attributed to the ground state, and one about 11 MeV higher in excitation. The peak near 11 MeV excitation energy is believed to be almost entirely composed of a multiplet of three J/sup ..pi../ = 2/sup +/ states. Relativistic DWBA calculations imply support for the expectation that higher spin states are preferentially populated in the (..pi../sup +/,K/sup +/) reaction, compared to the (K/sup -/,..pi../sup -/) reaction in which lower spin states are excited. 29 refs., 40 figs.

2018-03-26

Australia has an increasing demand for a sustainable primary health care registered nursing workforce. Targeting graduate registered nurses who typically begin their nursing career in acute-care hospital settings is a potential workforce development strategy. We evaluated a graduate registered nurse Community Transition to Professional Practice Program which was designed specifically to develop and foster skills required for primary health care. The aims of this study were to evaluate graduates' intention to remain in the primary health care nursing workforce, and graduate competency, confidence and experiences of program support; these were compared with graduates undertaking the conventional acute-care transition program. Preceptor ratings of graduate competence were also measured. All of the 25 graduates (n = 12 community, n = 13 acute-care) who completed the questionnaire at 6 and 12 months intended to remain in nursing, and 55% (n = 6) of graduates in the Community Transition Program intended to remain in the primary health care nursing workforce. There were no differences in graduate experiences, including level of competence, or preceptors' perceptions of graduate competence, between acute-care and Community Transition Programs. The Community Transition to Professional Practice program represents a substantial step towards developing the primary health care health workforce by facilitating graduate nurse employment in this area.

H.L. Santos

2002-03-01

Full Text Available SDS, C12E8, CHAPS or CHAPSO or a combination of two of these detergents is generally used for the solubilization of Na,K-ATPase and other ATPases. Our method using only C12E8 has the advantage of considerable reduction of the time for enzyme purification, with rapid solubilization and purification in a single chromatographic step. Na,K-ATPase-rich membrane fragments of rabbit kidney outer medulla were obtained without adding SDS. Optimum conditions for solubilization were obtained at 4ºC after rapid mixing of 1 mg of membrane Na,K-ATPase with 1 mg of C12E8/ml, yielding 98% recovery of the activity. The solubilized enzyme was purified by gel filtration on a Sepharose 6B column at 4ºC. Non-denaturing PAGE revealed a single protein band with phosphomonohydrolase activity. The molecular mass of the purified enzyme estimated by gel filtration chromatography was 320 kDa. The optimum apparent pH obtained for the purified enzyme was 7.5 for both PNPP and ATP. The dependence of ATPase activity on ATP concentration showed high (K0.5 = 4.0 µM and low (K0.5 = 1.4 mM affinity sites for ATP, with negative cooperativity. Ouabain (5 mM, oligomycin (1 µg/ml and sodium vanadate (3 µM inhibited the ATPase activity of C12E8-solubilized and purified Na,K-ATPase by 99, 81 and 98.5%, respectively. We have shown that Na,K-ATPase solubilized only with C12E8 can be purified and retains its activity. The activity is consistent with the form of (alphaß2 association.

The purpose of this study was to analyze the effectiveness of an online medical laboratory technician program in the academic preparation and development of laboratory professionals. A semi-quantitative comparative research design was used. Several factors were considered in this evaluation. Academic outcomes between online and campus medical laboratory technician (MLT) students was determined by comparing overall and categorical scores on certification exams as well as first time pass rate. Certification exam scores and first time pass rates were also compared to national norms when possible to do so. Demographic data, including age and experience were compared. Additionally, learning styles were assessed to determine if there was a correlation to overall GPA and MLT GPA and if learning styles could be used to predict successful completion of an online Associates of Applied Science. The research was conducted at an academic university located in the mountain west United States. Participants consisted of online and campus students enrolled in a Medical Laboratory Technician program that graduated with their Associate of Applied Science degree between the years 2007-2009. Results of these years were also compared to graduates from 2004-2006 in the same program. Certification performance and first time pass rates were the major outcomes measured. Age and experience were correlated. Online learning styles and GPA were also compared to successful degree completion. The researcher found no significant difference in certification performance with regard to total and categorical scores, and first time pass rates between campus and online MLT students. Online students were slightly older and had more experience working in a laboratory in some capacity. Correlation studies showed significant positive correlation between learning styles, GPA, and successful completion of an Associate of Applied Science degree.

A cross-countries and interprofessional novel approach for delivering an international interdisciplinary graduate health informatics course online is presented. Included in this discussion are the challenges, lessons learned, and pedagogical recommendations from the experiences of teaching the course. Four professors from three different fields and from three universities collaborated in offering an international health informatics course for an interdisciplinary group of 18 US and seven Norwegian students. Highly motivated students and professors, an online technology infrastructure that supported asynchronously communication and course delivery, the ability to adapt the curriculum to meet the pedagogy requirements at all universities, and the support of higher administration for international collaboration were enablers for success. This project demonstrated the feasibility and advantages of an interdisciplinary, interprofessional, and cross-countries approach in teaching health informatics online. Students were able to establish relationships and conduct professional conversations across disciplines and international boundaries using content management software. This graduate course can be used as a part of informatics, computer science, and/or health science programs.

Zakaria, Mohd Hafiz; Yatim, Bidin; Ismail, Suzilah

2014-06-01

Globalization makes graduate recruitment for an organization becomes more complex because employers believe that a holistic workforce is the key success of an organization. Currently, although graduates are said to possess specific skills but they still lack of employability skills, and this lead to increment of training cost either by government or even employers. Therefore, graduate level of employability skills should be evaluated before entering work market. In this study, a valid and reliable instrument embedding a new approach of measuring employability skills was developed using Situational Judgment Test (SJT). The instrument comprises of twelve (12) items measuring communication skill, professional ethics and morality, entrepreneurial skill, critical thinking in problem solving and personal quality. Instrument's validity was achieved through expert opinion and the reliability (in terms of stability) was based on the Chi-Square for homogeneity test. Generally, the instrument is beneficial to graduates, employers, government agencies, university, and workforce recruitment agencies when evaluating the level of employability skills.

Mixed methods of research design, predominantly concurrent nested strategy were employed to conduct the study. The study involved 162 instructors, 123 Level III automotive technology trainees, 87 department heads and 89 graduates, a total of 461 respondents as a sample. Moreover, 24 respondents (6 industry owners, 6 TVET college deans, 6 competence-based process owners and 6 industry trainers’ leaders were purposely selected for interview and focus group discussion. Under the study, the researcher used employability of graduates as dependent variable and competency based training as independent variable. Descriptive and inferential statistics were employed for data analysis. The study result showed that technical and vocational education and training (TVET colleges in Ethiopia have been performing below expectations in developing demand-based curriculum and implementing competence-based training in TVET colleges and industries. As a result, among the graduates nearly 50 percent are not employed in the past two years. Hence, it is recommended that constantly consulting and involving relevant stakeholders in setting study profile, identifying intended learning outcomes and strengthening competence based learning style are vital for graduates to demonstrate employability skill, knowledge and attitude into the job that consequentially lead to graduate employment.First published online: 30 November 2017

Promoting Inclusive Holistic Graduate Admissions in Educational Leadership Preparation Programs

Directory of Open Access Journals (Sweden)

Christa Boske

2018-04-01

Full Text Available Aspiring and practicing school leaders often identify graduate degrees as playing a significant role in achieving educational access and engaging in building, district-wide, regional, state, and national decision-making regarding practice and policy impacting marginalized populations in K–12 U.S. schools. The rationale behind initiating discourse on graduate student involvement grows out of current policy and reform initiatives requiring increased accountability for improved student performance, especially for children from predetermined “subgroups” due to race, class, native language, and ability (i.e., emotional, social, cognitive, and physical. The call for more deliberate involvement in understanding graduate admissions also arises in regard to student attrition and retention concerns. Faculty often play an under-examined role as gatekeepers throughout the admissions process. The way in which they understand graduate requirements, holistic evaluation, and merit affords opportunities to positively address significant implications for racial equity and diversity in graduate education. To understand faculty reliance upon graduate admissions criteria that undermine espoused university strategic plans, college-level diversity goals, and programmatic decision-making, four professors across the U.S. explore graduate admissions processes and the significance of implementing holistic admissions criteria. We present a holistic graduate admissions conceptual model for school leadership preparation programs to consider when increasing equity and access for minoritized candidates.

This study collected information on four main aspects of U.S. and Canadian orthodontic programs: demographic profiles of residents, requirements for graduation, graduate curriculum, and number of faculty and staff members. Program directors at seventy U.S. and Canadian orthodontic programs were invited to participate in a twenty-question survey and to distribute a ten-question survey to their residents. Twenty program directors and eighty-four residents completed the anonymous, online surveys on Qualtrics.com in July-August 2010. The average age of surveyed residents was 29.6 years of age; 73 percent were non-Hispanic white, with 14 percent Asian/Asian-American, 5 percent Hispanic, and 1 percent African American. A small percentage of residents (13 percent) were foreign-trained. The majority of residents (64 percent) were male. There was a wide variety of clinical and didactic requirements in the programs. Almost all programs emphasized treatment with functional appliances and clear aligners. An average of three full-time and ten part-time faculty members were dedicated to each residency program. This survey reveals a potential shortage of minority orthodontic residents currently being trained in orthodontic programs, in addition to several commonalities and differences among the programs' curricula, graduation requirements, and numbers of faculty and staff members. This preliminary survey will hopefully inspire measures to address the discrepancies revealed, particularly the lack of minority students and full-time faculty members.

Implementing compact, low-power artificial neural processing systems with real-time on-line learning abilities is still an open challenge. In this paper we present a full-custom mixed-signal VLSI device with neuromorphic learning circuits that emulate the biophysics of real spiking neurons and dynamic synapses for exploring the properties of computational neuroscience models and for building brain-inspired computing systems. The proposed architecture allows the on-chip configuration of a wide range of network connectivities, including recurrent and deep networks, with short-term and long-term plasticity. The device comprises 128 K analog synapse and 256 neuron circuits with biologically plausible dynamics and bi-stable spike-based plasticity mechanisms that endow it with on-line learning abilities. In addition to the analog circuits, the device comprises also asynchronous digital logic circuits for setting different synapse and neuron properties as well as different network configurations. This prototype device, fabricated using a 180 nm 1P6M CMOS process, occupies an area of 51.4 mm(2), and consumes approximately 4 mW for typical experiments, for example involving attractor networks. Here we describe the details of the overall architecture and of the individual circuits and present experimental results that showcase its potential. By supporting a wide range of cortical-like computational modules comprising plasticity mechanisms, this device will enable the realization of intelligent autonomous systems with on-line learning capabilities.

Polin, Linda G.

This chapter describes academic life at the intersection of three related topics: community of practice (CoP), a pedagogical model; digital culture, as embodied in the current and future student population; and post-secondary education, in particular graduate professional education. The aim is to illustrate ways in which social computing applications enable the use of a CoP model in graduate professional education. The illustrations are drawn from two hybrid, or blended, degree programs (a mix of face-to-face and online interactions) at the graduate school of education and psychology at Pepperdine University. These fully accredited programs have each been in operation for more than a decade. One is the MA degree in educational technology, begun in 1998; the other is the EdD degree in educational technology leadership, begun in 1995.

To better understand the molecular basis underlying aphid immune tolerance to beneficial bacteria and immune defense to pathogenic bacteria, we characterized how the pea aphid Acyrthosiphon pisum responds to Escherichia coli K-12 infections. E. coli bacteria, usually cleared in the hemolymph of other insect species, were capable of growing exponentially and killing aphids within a few days. Red fluorescence protein expressing E. coli K-12 laboratory strain multiplied in the aphid hemolymph as well as in the digestive tract, resulting in death of infected aphids. Selected gene deletion mutants of the E. coli K-12 predicted to have reduced virulence during systemic infections showed no difference in either replication or killing rate when compared to the wild type E. coli strain. Of note, however, the XL1-Blue E. coli K-12 strain exhibited a significant lag phase before multiplying and killing aphids. This bacterial strain has recently been shown to be more sensitive to oxidative stress than other E. coli K-12 strains, revealing a potential role for reactive oxygen species-mediated defenses in the otherwise reduced aphid immune system.

2009-01-01

Objective To design and evaluate a preregistration course utilizing asynchronous online learning as the primary distance education delivery method. Design Online course components including tutorials, quizzes, and moderated small-group asynchronous case-based discussions were implemented. Online delivery was supplemented with self-directed and face-to-face learning. Assessment Pharmacy graduates who had completed the course in 2004 and 2005 were surveyed. The majority felt they had benefited from all components of the course, and that online delivery provided benefits including increased peer support, shared learning, and immediate feedback on performance. A majority of the first cohort reported that the workload associated with asynchronous online discussions was too great. The course was altered in 2005 to reduce the online component. Participant satisfaction improved, and most felt that the balance of online to face-to-face delivery was appropriate. Conclusion A new pharmacy preregistration course was successfully implemented. Online teaching and learning was well accepted and appeared to deliver benefits over traditional distance education methods once workload issues were addressed. PMID:19777092

Structural insight into the rearrangement of the switch I region in GTP-bound G12A K-Ras

Energy Technology Data Exchange (ETDEWEB)

Xu, Shenyuan; Long, Brian N.; Boris, Gabriel H.; Chen, Anqi; Ni, Shuisong; Kennedy, Michael A.

2017-11-10

K-Ras, a molecular switch that regulates cell growth, apoptosis and metabolism, is activated when it undergoes a conformation change upon binding GTP and is deactivated following the hydrolysis of GTP to GDP. Hydrolysis of GTP in water is accelerated by coordination to K-Ras, where GTP adopts a high-energy conformation approaching the transition state. The G12A mutation reduces intrinsic K-Ras GTP hydrolysis by an unexplained mechanism. Here, crystal structures of G12A K-Ras in complex with GDP, GTP, GTPγS and GppNHp, and of Q61A K-Ras in complex with GDP, are reported. In the G12A K-Ras–GTP complex, the switch I region undergoes a significant reorganization such that the Tyr32 side chain points towards the GTP-binding pocket and forms a hydrogen bond to the GTP γ-phosphate, effectively stabilizing GTP in its precatalytic state, increasing the activation energy required to reach the transition state and contributing to the reduced intrinsic GTPase activity of G12A K-Ras mutants.

The National Science Foundation's Graduate Teaching Fellows in K-12 Education (GK-12) Program has enabled science, technology, engineering and mathematics (STEM) graduate schools across the country to become more active in local area K-12 schools. An overview of a graduate student's experiences, insights gained and lessons learned as a Fellow in the 2003-2004 Universidad Metropolitana's (UMET) environmental science and the 2004-2005 University of South Florida's (USF) ocean science GK-12 Programs is presented. The major goals of the 2003-2004 UMET GK-12 Program were 1) to enrich environmental science teaching and learning via a thematic approach in eight local public schools and 2) to provide UMET graduate students with exposure to teaching methodologies and practical teaching experience. Utilizing examples from local environments in and nearby Carolina, Puerto Rico to teach key science principles at Escuela de la Comunidad Juana Rodriguez Mundo provided numerous opportunities to relate science topics to students' daily life experiences. By 2004, the UMET GK-12 Program had successfully engaged the entire student body (primarily comprised of bilingual minority kindergarten to sixth graders), teachers and school administrators in environment-focused teaching and learning activities. Examples of such activities include tree planting projects to minimize local erosion, conducting a science fair for the first time in many years, and numerous opportunities to experience what "real scientists do" while conducting environmental science investigations. During the 2004-2005 academic year, skills, insights and lessons learned as a UMET GK-12 Fellow are being further enhanced through participation in the USF GK-12 OCEANS Program. The overall objectives of the 2004-2005 USF GK-12 OCEANS assignment at Madeira Beach Elementary School in Saint Petersburg, Florida are to 1) engage students from various ethnic backgrounds and cultures in hands-on science activities, 2) enhance the

Invisible Motivation of Online Adult Learners During Contract Learning

Directory of Open Access Journals (Sweden)

Seung Youn (Yonnie Chyung, Ed.D.

2007-07-01

Full Text Available In a face-to-face classroom, the instructor can easily diagnose students’ motivational status by observing their facial expressions and postures, but such cues are absent in an online classroom. Therefore, online instructors often estimate students’ motivational level based on their online behavior such as the number of messages they post, and look for effective strategies to help them actively participate in online dialogues. One such strategy is contract learning which facilitates self-directed behaviors through structuring an agreed learning process. This study reports a contract learning strategy in a graduate-level online class, examining whether a sample of 28 students’ motivation could indeed be predicted by their online behavior. Results from the study found that the students’ online behavior was not a predictor for their motivational status, though there were age and gender differences in their online behavior. The students felt more self-directed and motivated during contract learning, but what they really liked was being able to select assignments that were relevant to their interests and needs. This paper concludes by discussing practical implications of the findings at the end.

2001-01-01

Purpose: To inform the profession of current trends in the job market, the American College of Radiology (ACR) sought to detail the job-hunting experiences and outcomes of 1997 graduates of radiation oncology training programs. Methods and Materials: In early 1998, questionnaires were mailed to all graduates; 67% responded. Results were compared with similar surveys of 1996 graduates. Results: Similar to past years, immediately after graduation, 13% of residency graduates and 1 of 10 fellowship graduates encountered serious employment difficulties - that is, spent some time working locums, working outside radiation oncology, or unemployed. By 6-12 months after graduation, approximately 2% of all residency graduates were working outside the profession and approximately 3% were not working at all. Eighty-five percent of residency graduates and 7 of 8 fellowship graduates reported that their employment reasonably matched their training and individual goals. On average, graduates' actual salaries approximately corresponded to expected salaries. Eleven percent of all graduates were in nonownership-track jobs, a significant decline since 1996. For residents and fellows combined, 46% had a job with at least one characteristic some observers associate with a weak job market, but fewer than half of those with one of these characteristics actually disliked it. These percentages are similar to 1996. Women graduates were more likely than men to have spouse-related restrictions on job location but less likely to end up in a self-reportedly undesirable location. Conclusion: Unemployment remained low. Some other indicators of the employment market showed improvement, while others did not

Climate change is happening; scientists have already observed changes in sea level, increases in atmospheric carbon dioxide, and declining polar ice. The students of today are the leaders of tomorrow, and it is our duty to make sure they are well equipped and they understand the implications of climate change as part of their research and professional careers. Graduate students, in particular, are gaining valuable and necessary research, leadership, and critical thinking skills, but we need to ensure that they are receiving the appropriate climate education in their graduate training. Previous studies have primarily focused on capturing the K-12, college level, and general publics' knowledge of the climate system, concluding with recommendations on how to improve climate literacy in the classroom. While this is extremely important to study, very few studies have captured the current perception that graduate students hold regarding the amount of climate education being offered to them. This information is important to capture, as it can inform future curriculum development. We developed and distributed a nationwide survey (495 respondents) for graduate students to capture their perception on the level of climate system education being offered and their view on the importance of having climate education. We also investigated differences in the responses based on either geographic area or discipline. We compared how important graduate students felt it was to include climate education in their own discipline versus outside disciplines. The authors will discuss key findings from this ongoing research.

Accelerated nursing programs are gaining momentum as a means of career transition into the nursing profession for mature age learners in an attempt to meet future healthcare workforce demands in Australia. With a gap in the literature on readiness for practice of graduates from accelerated nursing programs at the Masters level the purpose of this study was to evaluate the effectiveness of the program based on graduates' preparedness for practice and graduate outcomes. Using a descriptive, exploratory design an online survey was used to explore the perception of graduate nurses' readiness for clinical practice. Forty-nine graduates from a nursing Masters program at an Australian university completed the survey defining readiness for practice as knowledge of self-limitations and seeking help, autonomy in basic clinical procedures, exhibiting confidence, possessing theoretical knowledge and practicing safe care. Graduates perceived themselves as adequately prepared to work as a beginner practitioner with their perception of readiness for clinical practice largely positive. The majority of participants agreed that the program had prepared them for work as a beginner practitioner with respondents stating that they felt adequately prepared in most areas relating to clinical practice. This would suggest that educational preparation was adequate and effective in achieving program objectives. Copyright © 2017 Elsevier Ltd. All rights reserved.

Females and STEM: Determining the K-12 Experiences that Influenced Women to Pursue STEM Fields

Science.gov (United States)

Petersen, Anne Marie

In the United States, careers in the fields of Science, Technology, Engineering, and Mathematics (STEM) are increasing yet there are not enough trained personnel to meet this demand. In addition, of those that seek to pursue STEM fields in the United States, only 26% are female. In order to increase the number of women seeking STEM based bachelor's degrees, K-12 education must provide a foundation that prepares students for entry into these fields. The purpose of this phenomenological study was to determine the perceived K-12 experiences that influenced females to pursue a STEM field. Twelve college juniors or seniors seeking a degree in Biology, Mathematics, or Physics were interviewed concerning their K-12 experiences. These interviews were analyzed and six themes emerged. Teacher passion and classroom characteristics such as incorporating challenging activities played a significant role in the females' decisions to enter STEM fields. Extra-curricular activities such as volunteer and mentor opportunities and the females' need to benefit others also influenced females in their career choice. Both the formal (within the school) and informal (outside of the traditional classroom) pipeline opportunities that these students encountered helped develop a sense of self-efficacy in science and mathematics; this self-efficacy enabled them to persist in pursuing these career fields. Several participants cited barriers that they encountered in K-12 education, but these barriers were primarily internal as they struggled with overcoming self-imposed obstacles in learning and being competitive in the mathematics and science classrooms. The experiences from these female students can be used by K-12 educators to prepare and encourage current female students to enter STEM occupations.

Design/Setting/Participants A national cross-sectional survey from a sample of residents and fellows who completed an online bullying survey conducted in June 2015. The survey was distributed using a chain sampling method that relied on electronic referrals from 4,055 training programs, with 1,791 residents and fellows completing the survey in its entirety. Survey respondents completed basic demographic and programmatic information plus four general bullying and 20 specific bullying behavior questions. Between-group differences were compared for demographic and programmatic stratifications. Main Outcomes/Measures Self-reported subjected to workplace bullying from peers, attendings, nurses, ancillary staff, or patients in the past 12 months. Results Almost half of the respondents (48%) reported being subjected to bullying although both those subjected and not subjected reported experiencing ≥ 1 bullying behaviors (95% and 39% respectively). Attendings (29%) and nurses (27%) were the most frequently identified source of bullying, followed by patients, peers, consultants and staff. Attempts to belittle and undermine work and unjustified criticism and monitoring of work were the most frequently reported bullying behaviors (44% each), followed by destructive innuendo and sarcasm (37%) and attempts to humiliate (32%). Specific bullying behaviors were more frequently reported by female, non-white, shorter than bullying in the United States graduate medical education programs. Including specific questions on bullying in the Accreditation Council for Graduate Medical Education annual resident/fellow survey, implementation of anti-bullying policies, and a multidisciplinary approach engaging all stakeholders may be of great value to eliminate these pervasive behaviors in the field of

Arterial stiffness is associated with cardiovascular risk, morbidity, and mortality. The present paper reviews the main vitamins related to arterial stiffness and enabling destiffening, their mechanisms of action, providing a brief description of the latest studies in the area, and their implications for primary cardiovascular prevention, clinical practice, and therapy. Despite inconsistent evidence for destiffening induced by vitamin supplementation in several randomized clinical trials, positive results were obtained in specific populations. The main mechanisms are related to antiatherogenic effects, improvement of endothelial function (vitamins A, C, D, and E) and metabolic profile (vitamins A, B12, C, D, and K), inhibition of the renin-angiotensin-aldosterone system (vitamin D), anti-inflammatory (vitamins A, D, E, and K) and antioxidant effects (vitamins A, C, and E), decrease of homocysteine level (vitamin B12), and reversing calcification of arteries (vitamin K). Vitamins A, B12, C, D, E, and K status is important in evaluating cardiovascular risk, and vitamin supplementation may be an effective, individualized, and inexpensive destiffening therapy.

Comprehensive experimental resources, such as ORFeome clone libraries and deletion mutant collections, are fundamental tools for elucidation of gene function. Data sets by omics analysis using these resources provide key information for functional analysis, modeling and simulation both in individual and systematic approaches. With the long-term goal of complete understanding of a cell, we have over the past decade created a variety of clone and mutant sets for functional genomics studies of Escherichia coli K-12. We have made these experimental resources freely available to the academic community worldwide. Accordingly, these resources have now been used in numerous investigations of a multitude of cell processes. Quality control is extremely important for evaluating results generated by these resources. Because the annotation has been changed since 2005, which we originally used for the construction, we have updated these genomic resources accordingly. Here, we describe GenoBase (http://ecoli.naist.jp/GB/), which contains key information about comprehensive experimental resources of E. coli K-12, their quality control and several omics data sets generated using these resources. © The Author(s) 2014.

ABSTRACT The state of science, technology, engineering and math (STEM) education in the United States has seen some unfavorable assessments over the past decade. In early February, 2010 the House of Representatives heard testimony on undergraduate and graduate education. The message from the panel, which included experts from academia, STEM-based industries, and the National Science Foundation (NSF) was dire and required an urgent response. The experts along with the committee's chairperson, U. S. Representative Daniel Lipinski (D-IL) cited that the complexity of Science, Technology, Engineering, and Mathematics applications and coursework and the methodology utilized to teach these subjects are forcing students out of these disciplines. As the National Academies described in its 2007 report Rising Above the Gathering Storm, successful STEM education is not just an academic pursuit it's a necessity for competing in the knowledge-based economy that the United States had a key role in creating. The potential for action is being made available again as the America COMPETES Act of 2007 is up for reauthorization. Its initial focus was on STEM education at the K-12 levels, but efforts at the undergraduate and graduate levels are needed to retain students to fill the jobs left vacant as baby boomers retire. The Educational Advancement Alliance, Inc. (EAA) has for two decades created programs that have not only addressed the issues of ensuring that students are aptly prepared for college but have focused its efforts over the past decade on increasing the number of students who pursue degrees in STEM disciplines. For the EAA, the introduction of the wonders of science begins at the elementary and middle school level via the Learning Lab, a state-of-the-art mobile science laboratory that visits students in grades 4-6 at the various schools throughout Philadelphia and The Math/Tech Academy which meets on Saturdays for students in grades 5-7.

To explore the thesis experience of recent Master of Health Professions Education (MHPE) graduates in the University of Illinois at Chicago (UIC) program. This is a qualitative case study exploring the experience of MHPE graduates between 2014 and 2016 (n=31). Using convenience sampling, all graduates with an email address (n=30) were invited to participate in an online survey and semi-structured interviews. Interviews were completed in-person or via telephone or video conference; interviewers collected detailed notes and audio recordings.  Two authors independently analyzed the data iteratively using thematic analysis and discrepancies were discussed and resolved. Survey results (n=20, 67%) revealed an average graduation of 5.1 years; 10 graduates (33%) were interviewed. Three themes related to the thesis experience were identified: success factors, challenges, and outcomes. Success factors, when present, promoted completion of a thesis; these included: a supportive program environment, time management, available resources, MHPE foundational coursework, aligning theses with career goals, and identifying a project with limited scope. Challenges made thesis completion more difficult for graduates; these included: institutional factors, personal or professional responsibilities, burnout, externally-imposed deadlines, and barriers in the research process. Despite these challenges, completing the thesis resulted in many professional or personal benefits (outcomes). Multiple success factors and challenges were identified in the master's thesis process among MHPE graduates at UIC. These findings can help students conducting education-based scholarship through the master's thesis process. This study also informs program evaluation and improvements and outlines personal and professional outcomes of completing a master's thesis.

The Polaris Project is a unique undergraduate education, research, and outreach initiative that examines global climate change in the Siberian Arctic. The program focuses on permafrost and carbon processes in the boreal and tundra ecosystems of the Kolyma Watershed, the largest watershed underlain by continuous permafrost. Each summer, a diverse group of undergraduate students and faculty mentors spends one month living on the Kolyma River, developing independent projects that engage the students directly in the biogeosciences through authentic scientific research experiences in remote field sites. In all cases the student projects contribute to the overall goal of the Polaris Project to investigate the transport and transformations of carbon and nutrients as they move among terrestrial and aquatic ecosystems and the atmosphere. Through the use of online interactive ArcGIS maps the students share their experiences and learning, while posing questions in a format that can be used to engage K-12 learners in the classroom. By embedding information; including databases, photographs and video, informational text, and geospatial data; into user-friendly maps the Polaris Project students will "tell the story" of studying climate change in the Siberian tundra in a way that allows the users to explore climate science through inquiry and web-map based investigation. Through performance expectation topics including Weather and Climate, Interactions, Earth's Systems, and Human impacts, this investigation uses consideration of the vast amounts of ancient organic matter locked up in permafrost in the region, and concerns about the fate of this ancient organic carbon as temperatures warm and permafrost thaws, to make K-12 climate change connections with the Next Generation Science Standards (NGSS).

Recently, we reported on the anti-ageing effects of K6PC-5. This compound induced keratinocyte differentiation and fibroblast proliferation by increasing sphingosine-1 phosphate synthesis. We performed this study to confirm the anti-ageing effects of new synthetic products (the K6EAA series) derived from K6PC-5 through an amino group induction. Cellular responses such as differentiation, proliferation and calcium mobilization were investigated using cultured human keratinocytes and fibroblasts. Also, we measured the expressions of collagen mRNA and protein using real time RT-PCR and ELISA, respectively. The K6EAA-L12 product, selected by in vitro screening, was evaluated for anti-ageing effects on intrinsically and extrinsically (photo) aged models of hairless mice. In the intrinsically aged murine skin, K6EAA-L12 showed anti-ageing effects by activating collagen synthesis, eventually causing dermal thickening. Also, in the photo-aged skin, the dermal collagen density and dermal thickness were increased. In photo-aged murine skin, K6EAA-L12 increased stratum corneum integrity by increasing corneodesmosome density and improved the barrier recovery rate. However, there were no changes in the expressions of epidermal differentiation maker proteins. In conclusion, topical K6EAA-L12, a new synthetic K6PC-5 derivative, improves intrinsically and extrinsically (photo) aged skin by increasing the collagen density and improving the skin barrier function. © 2011 John Wiley & Sons A/S.

Point mutations of the K-ras gene located in codons 12 and 13 cause poor responses to the anti-epidermal growth factor receptor (anti-EGFR) therapy of colorectal cancer (CRC) patients. Besides, mutations of K-ras gene have also been proven to play an important role in human tumor progression. We established a simple and effective capillary electrophoresis (CE) method for simultaneous point mutation detection in codons 12 and 13 of K-ras gene. We combined one universal fluorescence-based nonhuman-sequence primer and two fragment-oriented primers in one tube, and performed this two-in-one polymerase chain reaction (PCR). PCR fragments included wild type and seven point mutations at codons 12 and 13 of K-ras gene. The amplicons were analyzed by single-strand conformation polymorphism (SSCP)-CE method. The CE analysis was performed by using a 1x Tris-borate-EDTA (TBE) buffer containing 1.5% (w/v) hydroxyethylcellulose (HEC) (MW 250,000) under reverse polarity with 15 degrees C and 30 degrees C. Ninety colorectal cancer patients were blindly genotyped using this developed method. The results showed good agreement with those of DNA sequencing method. The SSCP-CE was feasible for mutation screening of K-ras gene in populations.

From the Classroom to the Keyboard: How Seven Teachers Created Their Online Teacher Identities

Directory of Open Access Journals (Sweden)

Jennifer C. Richardson

2015-02-01

Full Text Available Teacher identity is defined as a sense of teacher self that results from a productive combination of key personal and professional subjectivities or beliefs. Much empirical research has been done on the development of teacher identity in the K-12 arena, with a great deal of theoretical and philosophical scholarship about teaching at the college level, yet little research to date has looked at how instructors at the college level, especially those who are teaching online, develop their online instructor identity. The purpose of this interview-based, qualitative study is to understand the experience of first time online instructors and how they develop their online teacher identity and utilizes the framework established by Beijaard, Meijer and Verloop (2004 as the lens for analyses. Recommendations are made for cultivating online teacher identity and the many aspects of it as a means to strengthen online teacher identity to not only provide effective and innovative teaching experiences but also for the sake of retention.

2017-12-01

Within the context of growing concerns about a potential oversupply of occupational therapist, this research examines when, where and how long new graduates take to gain employment and identifies influences upon the health and university systems. A mixed method research design, using an online survey was adopted to investigate the topic. Two consecutive cohorts of graduates from a single university program were invited to participate. Seventy-five (58%) responses were received, with 63 (84%) currently employed in an occupational therapy role. Of the 12 (16%) not employed, only 3 (4%) described themselves as actively seeking employment in an occupational therapy role. A wide spread of employment settings and scope of practice areas was reported. Findings suggest that occupational therapy graduates are gaining employment in a range of settings and practice areas, relatively quickly. This research adds evidence to the conversation around graduate employment within a region of Australia. The Australian population, health system and university changes are possible factors influencing employment. The research reveals the difficulties in understanding the current situation with limitations in data collected, varied terminology and an ever changing job seeking environment. The research provides a starting point for the occupational therapy profession to further understand the directions the profession is taking. University programs may also benefit by using the research to tailor course content to assist graduates in gaining employment or to present students with the prospects of new employment opportunities. © 2017 Occupational Therapy Australia.

Perivascular adipocyte (PVAC) proliferation and differentiation were closely involved in cardiovascular disease. We aimed to investigate whether phosphatidylinositol 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) signaling pathways enhance PVAC functions activated by insulin-like growth factor 1(IGF-1) and suppressed by mesenchyme homeobox 2 (MEOX2). In this study, PVACs from primary culture were cultured and induced to differentiate. Cell viability assays demonstrated that IGF-1 promoted PVAC proliferation and differentiation. However MEOX2 counteracted these IGF-1-mediated actions. Flow Cytometry revealed that IGF-1 increased S phase cells and decreased apoptosis; however, MEOX2 decreased S phase cells, increased G0–G1 phase cells, and promoted apoptosis. During PVAC proliferation and differentiation, IGF-1 activated PI3K/Akt1/2 and ERK1/2 signaling pathways, upregulated the expression of these signaling proteins and FAS, and increased PVAC lipid content. In contrast, MEOX2 constrained the phosphorylation of ERK1/2 and Akt1/2 protein, down-regulated these signaling molecules and FAS, and decreased PVAC lipid content. Instead, MEOX2 knockdown enhanced the ERK1/2 and Akt1/2 phosphorylation, augmented the expression of these signaling molecules and FAS, and increased PVAC lipid content. Our findings suggested that PI3K/Akt1/2 and ERK1/2 activation mediated by IGF-1 is essential for PVAC proliferation and differentiation, and MEOX2 is a promising therapeutic gene to intervene in the signaling pathways and inhibit PVAC functions. - Highlights: • IGF-1 activated PI3K/Akt2 and ERK1/2 pathways to mediate PVAC proliferation and differentiation. • The expression of ERK1, ERK 2, PI3K, Akt1 and Akt2 showed different change trends between PVAC proliferation and differentiation. • MEOX2 effectively expressed in PVAC, increased early and late cellular apoptosis, and inhibited its proliferation. • MEOX2 depressed PVAC differentiation and FAS expression

Full Text Available In this article I will share a qualitative self-study about a 15-week blended 100% online graduate level course facilitated through synchronous meetings on Blackboard Collaborate and asynchronous discussions on Blackboard. I taught the course at the University of Tennessee (UT during the spring 2012 semester and the course topic was online learning environments. The primary research question of this study was: How can the designer/instructor optimize learning experiences for students who are studying about online learning environments in a blended online course relying on both synchronous and asynchronous technologies? I relied on student reflections of course activities during the beginning, middle, and the end of the semester as the primary data source to obtain their insights regarding course experiences. Through the experiences involved in designing and teaching the course and engaging in this study I found that there is room in the instructional technology research community to address strategies for facilitating online synchronous learning that complement asynchronous learning. Synchronous online whole class meetings and well-structured small group meetings can help students feel a stronger sense of connection to their peers and instructor and stay engaged with course activities. In order to provide meaningful learning spaces in synchronous learning environments, the instructor/designer needs to balance the tension between embracing the flexibility that the online space affords to users and designing deliberate structures that will help them take advantage of the flexible space.

Textured (Bi1/2K1/2)TiO3 (BKT) ceramics were prepared by a reactive templated grain growth (RTGG) method to improve their piezoelectric properties. Also, a hot-pressing (HP) method was modified on the basis of RTGG method to obtain dense ceramics and promote the grain orientation. The textured BKT ceramics prepared by the RTGG and HP methods exhibited a relatively high orientation factor F of 0.82 and a high density ratio of 95-99%. Scanning electron microscopy (SEM) micrographs of the textured HP-BKT indicated a textured and poreless microstructure. In addition, the resistivity of the textured HP-BKT was 1.73×1013 Ω·cm. The piezoelectric strain constant d33 determined by means of resonance and antiresonance method was 125 pC/N for the direction parallel to the sheet-stacking direction of the RTGG process. From the measurement of field-induced stain, the normalized d33* (=Smax/Emax) at 80 kV/cm were 127 and 238 pm/V on the randomly oriented and textured samples (F=0.82) for the (∥) direction, respectively.

Choosing to pursue an advanced degree in athletic training appears to indicate professional commitment and passion for the profession. Currently, there is a paucity of information regarding why some athletic trainers pursue enrollment in a postprofessional athletic training program (PPATP), indicating commitment to the profession, but later depart for another primary role outside of athletic training. To understand why athletic trainers invested in advanced training via a PPATP but then decided to leave the profession. Qualitative study. Online data collection. Twelve graduates (8 women [67%], 4 men [33%], age = 31.58 ± 3.06 years) from PPATPs who no longer had primary employment as an athletic trainer. Recruits responded to an e-mail invitation to participate by completing a confidential online questionnaire. We analyzed data using a general inductive approach and secured trustworthiness using multiple-analyst triangulation, peer review, and member checks. Two higher-order themes emerged regarding the career commitment of former athletic trainers who were PPATP graduates: (1) departure from an athletic training career and (2) partial continuance in athletic training. Two second-order themes emerged from the reasons for departure: (1) decreased recognition of value and (2) work-life imbalance. Finally, we identified 2 third-order themes from the participants' reasons for departure because of a perceived lack of value: (1) low salary and (2) long, inconsistent hours worked. Most of our participants intended to stay in the profession when they chose to attend a PPATP. However, during role inductance in either the clinical experience of the PPATP they attended or early in their careers, they began to have thoughts of leaving mainly because of inadequate financial compensation, challenging work schedules, or both.

A new potassium europium borate K{sub 3}EuB{sub 6}O{sub 12} has been prepared using a high temperature molten salt method and structurally characterized by single crystal X-ray diffraction (SC-XRD) analyses. Its structure features a three-dimensional (3D) framework composed of isolated [B{sub 5}O{sub 10}]{sup 5−} anions that are bridged by K{sup +} and Eu{sup 3+} ions. In this structure, one crystallographic distinct atom site is mixed occupied by K/Eu at a molar ratio of 1:1. The self-activated photoluminescence (PL) of K{sub 3}EuB{sub 6}O{sub 12} was studied. The excitation spectrum covers a wide range from 322 to 466 nm, which suggests that the K{sub 3}EuB{sub 6}O{sub 12} phosphors can be effectively excited by a near-UV light source. The emission spectrum consists of groups of lines in the red spectral region due to the {sup 5}D{sub 0}→{sup 7}F{sub j} (j = 1, 2, 3, 4) electronic transitions of Eu{sup 3+} ions, with the most intense line at 611 nm. We may expect that K{sub 3}EuB{sub 6}O{sub 12} has the potential to be a red phosphor pumped by near-UV LED chips. - Highlights: • A new red phosphor K{sub 3}EuB{sub 6}O{sub 12} was prepared. • The crystal structure of K{sub 3}EuB{sub 6}O{sub 12} was determined for the first time. • The photoluminescence properties of K{sub 3}EuB{sub 6}O{sub 12} are studied. • K{sub 3}EuB{sub 6}O{sub 12} show intense self-activated red emission under near-UV light excitation.

Statistics indicate that most Americans learn what they will know about science within the confines of our public K-12 education system and the media. Next Generation Science Standards (NGSS) aim to remedy science illiteracy and provide guidelines to exceed the Common Core State Standards that most U.S. state governments have adopted, by integrating disciplinary cores with crosscutting ideas and real life practices. In this vein, we present a prototype ';Virtual Ice Sheet Laboratory' (I-Lab), geared to K-12 students, educators and interested members of the general public. I-Lab will allow users to perform experiments using a state-of-the-art dynamical ice sheet model and provide detailed downloadable lesson plans, which incorporate this model and are consistent with NGSS Physical Science criteria for different grade bands (K-2, 3-5, 6-8, and 9-12). The ultimate goal of this website is to improve public climate science literacy, especially in regards to the crucial role of the polar ice sheets in Earth's climate and sea level. The model used will be the Ice Sheet System Model (ISSM), an ice flow model developed at NASA's Jet Propulsion Laboratory and UC Irvine, that simulates the near-term evolution of polar ice sheets (Greenland and Antarctica) and includes high spatial resolution capabilities and data assimilation to produce realistic simulations of ice sheet dynamics at the continental scale. Open sourced since 2011, ISSM is used in cutting edge cryosphere research around the globe. Thru I-Lab, students will be able to access ISSM using a simple, online graphical interface that can be launched from a web browser on a computer, tablet or smart phone. The interface will allow users to select different climate conditions and watch how the polar ice sheets evolve in time under those conditions. Lesson contents will include links to background material and activities that teach observation recording, concept articulation, hypothesis formulation and testing, and
