    Full Text Available This study examined one program which was in place in a multi-track year-round elementary school, a tutoring program delivered during the students' intersession. Through interviews, surveys, and analysis of grades recorded on report cards, the program was evaluated to determine whether goals for the program were met. Survey data revealed that students, parents, and teachers all felt overwhelmingly that the program was effective at meeting stated program goals. Report card data did not show a statistically significant increase in grades after students attended the program, but many intervening variables were not controlled for. Additional convenience factors, such as transportation, cost, and timing contributed to the program benefits

    The Peer Mentor Tutor (PMT) program in the University of Wisconsin-Madison's Physics Department matches upper level undergraduate physics majors in small groups with students potentially at-risk for having academic trouble with their gateway introductory non-calculus physics course or for feeling isolated at the University. The program enhances students'learning and confidence by providing an emphasis on problem solving, a supportive environment for asking questions, and opportunities for acquiring missing math skills. The students assisted include, among others, returning adults, students of color,students with English as a second language, and students who have never taken physics in high school. The tutors acquire teaching and leadership experience with ongoing training throughout the year. The Physics PMT program is run in collaboration with a similar program in Chemistry. The peer model is also being applied to other science courses at the University of Wisconsin. We will describe the structure of the Physics PMT program and our current efforts to expand the program into a broader Physics Learning Center that may serve multiple purposes and courses.

    Due to the difficult and rigorous nature of nursing education, student retention and attrition are major concerns for faculty. This article describes the implementation and outcomes of a peer-based mentor tutor program (PMTP) for at-risk students in a traditional baccalaureate program. Funding was obtained to provide scholarship incentives for student participants and cover costs of training and materials. Criteria were determined for the selection of student mentors-tutors and the identification of at-risk students. Interventions consisted of weekly PMTP sessions offered for the first four semesters of nursing courses. Course grades were used to determine outcome differences between control and intervention groups. Students in the intervention group were found to score significantly higher than the control group on both summative and final grades.

    2015-03-01

    Full Text Available The Curtin Coaches program represents a dynamic outreach opportunity for pre-service teachers enrolled in their first year of study at Curtin University to engage with school-aged students as classroom tutors. Research has shown that cross-age tutoring experiences in schools can benefit both the students receiving support and those who tutor, particularly in settings where individuals are engaging in community support work. According to program feedback, participants were able to develop a range of profession-related skills such as relationship building and gain new knowledge such as understanding how students learn. These competencies are salient as they align with the newly implemented standards for graduate teachers. Understanding the benefits such outreach programs bring pre-service teachers is vital as the future of HEPPP funded programs such as the Curtin Coaches is uncertain but the importance of Work Integrated Learning is increasing.

    The tutor is important for student learning in the PBL group. The students expect the tutor to monitor and steer the group process and to support the learning process, helping students to become aware of their own learning. This study aimed at investigating the PBL tutor's role. Five PBL tutors at the Speech/Language Pathology program were interviewed regarding their view of the tutors' role and what support they need. The analysis of the transcribed interviews focused on finding patterns and variation regarding tutor-activity at different stages in the PBL work and in their views of their progress as tutors. The results indicate that being a tutor is a balancing act and that the tutor need continuous support and input from different sources. Tutors should be encouraged to reflect on their own reactions and interventions and to be explicit and confident in their thoughts about PBL.

    Full Text Available Teaching online requires different skills, roles and competencies for online instructors compared to teaching in traditional learning environments. Universities should offer ongoing support in various forms to help academic staff through their online journey. This paper provides insights into a multinational faculty development program for teaching online, elaborating on results of expectancy and satisfaction surveys. From a local program to a subproject within the Swiss National Science Foundation Project Scopes, e-Tutor aimed at expanding competencies in online lecturing and providing OER material for training colleagues. Designed in the form of a descriptive case study, this research was conducted with 34 attendees of e-Tutor. Data was collected using an e-learning readiness and expectancy questionnaire, and open-ended questions after the program to measure satisfaction. Descriptive statistics were used to analyze the survey data and content analysis for open-ended data. Participants considered e-Tutor a well-planned and targeted program with good theoretical and practical balance. Duration of such courses, opportunities for adaptation to real-life situations, and localization of the content are areas to be explored further. For future studies, it would also be interesting to see whether participants can apply their newly acquired knowledge and skills to create efficient online learning environments.

    This paper describes a pilot program in the use of high school near dropouts as tutors for young children. The work is set in the context of adolescent developmental tasks and draws its rationale from the general human tendency to reach mastery by turning passivity into activity. We ask whether adolescents who have experienced a decade of school failure and misery might use the opportunity for a new form of more active contact with the schools to master old failures. We reasoned that the very area of failure, where these adolescents show apparent uninterest through truancy and minimal work, must be a highly emotionally charged one (albeit negatively) precisely because it is an area of failure. After describing the setting and the rationale, we analyze the experience for several tutors from the point of view of their relationship to (1) the tutees, (2) the tutor-supervisor, (3) the group of adolescent tutors, and (4) the social system of the elementary school.

    A system for developing distributed robot application-level software includes a robot having an associated control module which controls motion of the robot in response to a commanded task, and a robot task commander (RTC) in networked communication with the control module over a network transport layer (NTL). The RTC includes a script engine(s) and a GUI, with a processor and a centralized library of library blocks constructed from an interpretive computer programming code and having input and output connections. The GUI provides access to a Visual Programming Language (VPL) environment and a text editor. In executing a method, the VPL is opened, a task for the robot is built from the code library blocks, and data is assigned to input and output connections identifying input and output data for each block. A task sequence(s) is sent to the control module(s) over the NTL to command execution of the task.

    1998-01-01

    This research investigates the combination of task and data parallel language constructs within a single programming language. There are an number of applications that exhibit properties which would be well served by such an integrated language. Examples include global climate models, aircraft design problems, and multidisciplinary design optimization problems. Our approach incorporates data parallel language constructs into an existing, object oriented, task parallel language. The language will support creation and manipulation of parallel classes and objects of both types (task parallel and data parallel). Ultimately, the language will allow data parallel and task parallel classes to be used either as building blocks or managers of parallel objects of either type, thus allowing the development of single and multi-paradigm parallel applications. 1995 Research Accomplishments In February I presented a paper at Frontiers 1995 describing the design of the data parallel language subset. During the spring I wrote and defended my dissertation proposal. Since that time I have developed a runtime model for the language subset. I have begun implementing the model and hand-coding simple examples which demonstrate the language subset. I have identified an astrophysical fluid flow application which will validate the data parallel language subset. 1996 Research Agenda Milestones for the coming year include implementing a significant portion of the data parallel language subset over the Legion system. Using simple hand-coded methods, I plan to demonstrate (1) concurrent task and data parallel objects and (2) task parallel objects managing both task and data parallel objects. My next steps will focus on constructing a compiler and implementing the fluid flow application with the language. Concurrently, I will conduct a search for a real-world application exhibiting both task and data parallelism within the same program. Additional 1995 Activities During the fall I collaborated

    The University of Wisconsin's Physics Peer Mentor Tutor Program matches upper level undergraduate physics students in small study groups with students studying introductory algebra-based physics. We work with students who are potentially at-risk for having academic trouble with the course. They include students with a low exam score, learning disabilities, no high school physics, weak math backgrounds, and/or on academic probation. We also work with students from groups under represented in the sciences and who may be feeling isolated or marginal on campus such as minority, returning adult, and international students. The tutors provide a supportive learning environment, extra practice problems, and an overview of key concepts. In so doing, they help our students to build confidence and problem solving skills applicable to physics and other areas of their academic careers. The Physics Peer Mentor Tutor Program is modeled after a similar program for chemistry created by the University of Wisconsin's Chemistry Learning Center. Both programs are now run in collaboration. The tutors are chosen for their academic strength and excellent communication skills. Our tutors are majoring in physics, math, and secondary-level science education. The tutors receive ongoing training and supervision throughout the year. They attend weekly discipline-specific meetings to discuss strategies for teaching the content currently being discussed in the physics course. They also participate in a weekly teaching seminar with science tutors from chemistry and biochemistry to discuss teaching methods, mentoring, and general information relating to the students with whom we work. We will describe an overview of the Physics Peer Mentor Tutor Program with a focus on the teacher training program for our undergraduate tutors.

    1990-01-01

    Two years ago Dr. Sherrie Gott of the Air Force Human Resources Laboratory described an avionics troubleshooting tutor being developed under the Basic Job Skills Research Program. The tutor, known as Sherlock, is directed at teaching the diagnostic procedures necessary to investigate complex test equipment used to maintain F-15 fighter aircraft. Since Dr. Gott's presentation in 1987, the tutor has undergone field testing at two Air Force F-15 flying wings. The results of the field test showed that after an average of 20 hours on the tutor, the 16 airmen in the experimental group (who average 28 months of experience) showed significant performance gains when compared to a control group (having a mean experience level of 37 months) who continued participating in the existing on-the-job training program. Troubleshooting performance of the tutored group approached the level of proficiency of highly experienced airmen (averaging approximately 114 months of experience), and these performance gains were confirmed in delayed testing six months following the intervention. The tutor is currently undergoing a hardware and software conversion form a Xerox Lisp environment to a PC-based environment using an object-oriented programming language. Summarized here are the results of the successful field test. The focus is on: (1) the instructional features that contributed to Sherlock's success; and (2) the implementation of these features in the PC-based version of the avionics troubleshooting tutor.

    2005-06-01

    Full Text Available Abstract Background Evidence for the superiority of particular characteristics in PBL tutors in medical curricula is generally inconclusive. Most studies have investigated the effectiveness of content experts compared with that of non-experts as measured either by student satisfaction or academic achievement. A few have compared academic staff tutors with student tutors. The purpose of this study was to investigate the relationship between students' perception of overall tutor effectiveness, particular tutor behaviours, clinical qualifications and academic appointment. Method A questionnaire designed to evaluate particular aspects of PBL tutoring technique, related either to subject-matter knowledge or to process-facilitation skill, as well as overall effectiveness, was distributed to students in first year of a PBL medical program at the end of each of three tutor terms. A total of 76 tutor terms were included in the study. Data analysis compared clinical with non-clinical tutors, and staff with non-staff tutors. Results Clinically qualified tutors used their subject-matter knowledge significantly more than non-clinical tutors and were seen as being more empathic with their students. Staff tutors placed more emphasis on assessment than non-staff tutors and were seen as having greater skill in establishing and maintaining an environment of cooperation within their PBL groups than non-staff tutors. Conclusion These results suggest that both subject-matter knowledge and process-facilitation skills are necessary but not individually sufficient characteristics of effective tutors.

    Full Text Available Introduction: Defining exactly what characterizes a clinical tutor as excellent and another less effective, is an important task in assessing the effectiveness of clinical training and guiding faculty development. Aim: We aimed to evaluate those characteristics and measure differences in their perception among accomplished and non-accomplished consultants and residents in the Emergency Department. We also compared perceptions between the different groups of participants. Methods: The characteristics measured were extracted from an extensive search of previously published studies summarized in a review article. A qualitative study was conducted, using a 20 item questionnaire piloted from the refined characteristics (good indicator of reliability; Cronbach′s Alpha = 0.86. The questionnaire was distributed among all consultants and residents in Saudi Board of Emergency Medicine. Results: No significant difference between consultants′ and residents′ perception was found. "Sincere" was an exception 87.8% versus 55.1%, P = 0.013. Consultants′ specifications did not seem to affect perception on overall scores and its component sub-scores. Conclusion: Since results showed no relation between accomplished and non-accomplished consultants in perceiving those qualities, we excluded the lack of knowledge of those characteristics as a cause of being accomplished or non-accomplished. We suggest a greater dedication from program developers towards creating more opportunities to involve more consultants in basic Emergency Medicine training.

    Full Text Available Abstract Background The aim of this study was to research the feasibility of training mental health consumers as tutors for 4th year medical students in psychiatry. Methods A partnership between a consumer network and an academic unit in Psychological Medicine was formed to jointly develop a training package for consumer tutors and a curriculum in interviewing skills for medical students. Student attitudes to mental health consumers were measured pre and post the program. All tutorial evaluation data was analysed using univariate statistics. Both tutors and students evaluated the teaching program using a 4 point rating scale. The mean scores for teaching and content for both students and tutors were compared using an independent samples t-test. Results Consumer tutors were successfully trained and accredited as tutors and able to sustain delivery of tutorials over a 4 year period. The study found that whilst the medical students started with positive attitudes towards consumers prior to the program, there was a general trend towards improved attitude across all measures. Other outcomes for tutors and students (both positive and negative are described. Conclusions Consumer tutors along with professional tutors have a place in the education of medical students, are an untapped resource and deliver largely positive outcomes for students and themselves. Further possible developments are described.

    In order to bring about positive changes in the education process of health professionals, the Ministries of Health and Education established the Education Program of Work for Health in 2008. The study aimed to achieve the consensus of a group of experts about the Program established at the University of São Paulo, Capital Campus, Brazil. The subjects of the study were the tutors who joined the program in 2010-2012. A qualitative approach was used based on the Delphi Technique. Among the data collected, tutors believe the program provides benefits to teaching practices and contributes to qualification of professionals involved in health services, and offers improvements for training in the health area. From the subjects' point of view, the tutors are the link between academia and the health services and the instructors are critical to ensure the effectiveness of activities. The staging of regular meetings and seminars help in the process. The main limitations are the lack of explicit commitment shown by some students and the high workload of undergraduate courses.

    Azer, Samy A

    2005-12-01

    One of the main tasks of a problem-based learning (PBL) tutor is to facilitate group discussion. Group facilitation is about process rather than content. In this process, a tutor helps the group increase their skills and progress in their discussion. Several studies have highlighted strategies and training used in preparing PBL tutors. However, PBL tutors usually feel that it is not that easy to change their teaching style to the PBL format. They are sometimes unsure about their role or what strategy they might use to facilitate their students' discussion. This article in the '12 Tips' series is a detailed description of, and provides answers to, common challenges faced by PBL tutors. The tips provided in this manuscript should help tutors with practical answers. The article may be useful to PBL tutors, medical and health educators and those responsible for PBL training workshops.

    2012-12-01

    Full Text Available Source code plagiarism in students solutions of programming tasks is a serious problem, especially important in distance learning. Naturally, it should be prevented, but publicly available code plagiarism detection tools are not fully adjusted to this purpose. This paper proposes the specific approach to detecting code duplicates. This approach is based on adapting of detection process to characteristics of programming tasks and comprise of freshly developed detecting tools, which could be configured and tuned to fit individual features of the programming task. Particular attention is paid to the possibility of an automatic elimination of duplicate codes from the set of all solutions. As a minimum, this requires the rejection of false-positive duplicates, even for simple, schematic tasks. The case in the use of tools is presented in this context. The discussion is illustrated by applying of proposed tools to duplicates detection in the set of actual, real-life, codes written in Java programming language.

  19. Characterizing and Mitigating Work Time Inflation in Task Parallel Programs

    Directory of Open Access Journals (Sweden)

    Stephen L. Olivier

    2013-01-01

    Full Text Available Task parallelism raises the level of abstraction in shared memory parallel programming to simplify the development of complex applications. However, task parallel applications can exhibit poor performance due to thread idleness, scheduling overheads, and work time inflation – additional time spent by threads in a multithreaded computation beyond the time required to perform the same work in a sequential computation. We identify the contributions of each factor to lost efficiency in various task parallel OpenMP applications and diagnose the causes of work time inflation in those applications. Increased data access latency can cause significant work time inflation in NUMA systems. Our locality framework for task parallel OpenMP programs mitigates this cause of work time inflation. Our extensions to the Qthreads library demonstrate that locality-aware scheduling can improve performance up to 3X compared to the Intel OpenMP task scheduler.

The framework that was established in the European Space for Higher Education for the development of the Tuning project and its later adaptation and implementation in Latin America (AL was considered. The aforementioned agencies have contributed to the creation of a normative framework for the development of competency-based education, an approach engaged by the Instituto Politecnico Nacional (IPN as part of its new educational model. During this research, two joint strategies were presented: auxiliary courses and a counseling program, both supported by the institutional tutoring pro­gram in order to reduce student failure and dropout rates. The results showed that there was a 22.72% decrease in failure rate when considering all the students that were enrolled during the semester. It can be concluded that auxiliary courses and counseling programs are an al­ternative that can help reduce student failure and dropout rates.El presente trabajo muestra las estrategias de intervención educativa como apoyo para redu­cir los índices de reprobación y deserción escolar apoyados por el programa institucional de tutorías, dentro de las tendencias de las políticas educativas para la Educación Superior (ES, tomando en consideración lo que establece el marco del espacio europeo de ES para la crea­ción del proyecto Tuning y su posterior adaptación y aplicación para América Latina (AL.

    2013-05-01

    Full Text Available Abstract We present an intuitive system for the programming of industrial robots using markerless gesture recognition and mobile augmented reality in terms of programming by demonstration. The approach covers gesture-based task definition and adaption by human demonstration, as well as task evaluation through augmented reality. A 3D motion tracking system and a handheld device establish the basis for the presented spatial programming system. In this publication, we present a prototype toward the programming of an assembly sequence consisting of several pick-and-place tasks. A scene reconstruction provides pose estimation of known objects with the help of the 2D camera of the handheld. Therefore, the programmer is able to define the program through natural bare-hand manipulation of these objects with the help of direct visual feedback in the augmented reality application. The program can be adapted by gestures and transmitted subsequently to an arbitrary industrial robot controller using a unified interface. Finally, we discuss an application of the presented spatial programming approach toward robot-based welding tasks.

    Students who supervised other students who tutored grade-school pupils in a university-based outreach program were randomly assigned to Pygmalion and control conditions. Experimental supervisors were told that their tutors were ideally qualified for their tutoring role; control supervisors were told nothing about their tutors' qualifications. A manipulation check revealed that the experimental supervisors expected more of their tutors. Analysis of variance of tutorial success measures confirmed the Pygmalion effect among supervisors of both sexes. No main effect or interaction involving either supervisor sex or tutor sex was significant. As predicted, the experimental supervisors also provided better leadership and the experimental tutors increased their self-efficacy. This was the first demonstration of the Pygmalion effect among women leading men. Pygmalion effects may be produced without regard for sex.

  10. SitLog: A Programming Language for Service Robot Tasks

    Directory of Open Access Journals (Sweden)

    Luis A. Pineda

    2013-10-01

    Full Text Available In this paper we present SitLog: a declarative situation-oriented logical language for programming situated service robot tasks. The formalism is task and domain independent, and can be used in a wide variety of settings. SitLog can also be seen as a behaviour engineering specification and interpretation formalism to support action selection by autonomous agents during the execution of complex tasks. The language combines the recursive transition network formalism, extended with functions to express dynamic and contextualized task structures, with a functional language to express control and content information. The SitLog interpreter is written in Prolog and SitLog’s programs follow closely the Prolog notation, permitting the declarative specification and direct interpretation of complex applications in a modular and compact form. We discuss the structure and representation of service robot tasks in practical settings and how these can be expressed in SitLog. The present framework has been tested in the service robot Golem-II+ using the specification and programming of the typical tasks which require completion in the RoboCup@Home Competition.

    2009-01-01

    This study examined the learning of teacher candidates taking a language arts course in a special-educator preparation program and that of the second graders they tutored in a supervised field component of the course. Teacher candidates' knowledge of literacy instruction was assessed using five knowledge tasks; children were assessed on several measures of basic reading and spelling skills as well as on their knowledge of phonics concepts such as syllable types. Teacher candidates generally had inaccurate perceptions of their knowledge at pretest, but their knowledge improved significantly on all tasks after course instruction. Tutored children improved significantly from pre- to posttest on all assessments. The study suggests that carefully designed literacy coursework with field experiences can benefit both prospective special educators and struggling readers.

  16. Integrated Task And Data Parallel Programming: Language Design

    Grimshaw, Andrew S.; West, Emily A.

    1998-01-01

    his research investigates the combination of task and data parallel language constructs within a single programming language. There are an number of applications that exhibit properties which would be well served by such an integrated language. Examples include global climate models, aircraft design problems, and multidisciplinary design optimization problems. Our approach incorporates data parallel language constructs into an existing, object oriented, task parallel language. The language will support creation and manipulation of parallel classes and objects of both types (task parallel and data parallel). Ultimately, the language will allow data parallel and task parallel classes to be used either as building blocks or managers of parallel objects of either type, thus allowing the development of single and multi-paradigm parallel applications. 1995 Research Accomplishments In February I presented a paper at Frontiers '95 describing the design of the data parallel language subset. During the spring I wrote and defended my dissertation proposal. Since that time I have developed a runtime model for the language subset. I have begun implementing the model and hand-coding simple examples which demonstrate the language subset. I have identified an astrophysical fluid flow application which will validate the data parallel language subset. 1996 Research Agenda Milestones for the coming year include implementing a significant portion of the data parallel language subset over the Legion system. Using simple hand-coded methods, I plan to demonstrate (1) concurrent task and data parallel objects and (2) task parallel objects managing both task and data parallel objects. My next steps will focus on constructing a compiler and implementing the fluid flow application with the language. Concurrently, I will conduct a search for a real-world application exhibiting both task and data parallelism within the same program m. Additional 1995 Activities During the fall I collaborated

    Robot programming by demonstration (PBD) system for task in which object requires contact with environment is built based on the controlling skill model. The skill is described in three aspects: contact state classifier, acquirement of contact states sequence and controlling transition between states. The classifier is developed with the support vector machine by using force sense. Sequence of states is obtained from the force signal of demonstration by the event trigger. The velocity command of transition is achieved by linearization method. The PBD system is successfully built with robot controller with open architecture.

  3. Stochastic dynamic programming applied to planning of robot grinding tasks

    Brown, M.L. (Digital Equipment Corp., Shrewsbury, MA (United States)); Whitney, D.E. (Massachusetts Inst. of Technology, Cambridge, MA (United States))

    1994-10-01

    This paper proposes an intelligent manufacturing system that can make decisions about the process in light of the uncertain outcome of these decisions and attempts to minimize the expected economic penalty resulting from those decisions. It uses robot weld bead grinding as an example of a process with significant process variations. The need for multiple grinding passes, the poor predictability of those passes, the task requirements, and the process constraints conspire to make planning and controlling weld bead grinding a formidable probe. A three tier hierarchical control system is proposed to plan an optimal sequence of grinding passes, dynamically simulate each pass, execute the planned sequence of controlled grinding passes, and modify the pass sequence as grinding continues. The top tier, described in this paper, plans the grinding sequence for each weld bead, and is implemented using Stochastic Dynamic Programming, selecting the volumetric removal and feedspeed for each pass in order to optimize the satisfaction of the task requirements by the entire grinding sequence within the equipment, task, and process constraints. The resulting optimal policies have quite complex structures, showing foresight, anxiety, indifference, and aggressiveness, depending upon the situation.

    Hart, Stephen; Dinh, Paul; Hambuchen, Kimberly

    2015-01-01

    This paper introduces the Affordance Template ROS package for quickly programming, adjusting, and executing robot applications in the ROS RViz environment. This package extends the capabilities of RViz interactive markers by allowing an operator to specify multiple end-effector waypoint locations and grasp poses in object-centric coordinate frames and to adjust these waypoints in order to meet the run-time demands of the task (specifically, object scale and location). The Affordance Template package stores task specifications in a robot-agnostic XML description format such that it is trivial to apply a template to a new robot. As such, the Affordance Template package provides a robot-generic ROS tool appropriate for building semi-autonomous, manipulation-based applications. Affordance Templates were developed by the NASA-JSC DARPA Robotics Challenge (DRC) team and have since successfully been deployed on multiple platforms including the NASA Valkyrie and Robonaut 2 humanoids, the University of Texas Dreamer robot and the Willow Garage PR2. In this paper, the specification and implementation of the affordance template package is introduced and demonstrated through examples for wheel (valve) turning, pick-and-place, and drill grasping, evincing its utility and flexibility for a wide variety of robot applications.

Therefore, this study aims at examining whether lecturing skills of faculty could predict their PBL tutoring skills. Methods: This study included evaluation of faculty (n=69 who participated in both tutoring and lecturing within particular PBL units at the College of Medicine and Medical Sciences (CMMS, Arabian Gulf University, Bahrain. Each faculty was evaluated by medical students (n=45±8 for lecturing and 8±2 for PBL tutoring using structured evaluation forms based on a Likert-type scale (poor to excellent. The prediction of tutoring skills using lecturing skills was statistically analyzed using stepwise linear regression. Results: Among the parameters used to judge lecturing skills, the most important predictor for tutoring skills was subject matter mastery in the lecture by explaining difficult concepts and responding effectively to students' questions. Subject matter mastery in the lecture positively predicted five tutoring skills and accounted for 25% of the variance in overall effectiveness of the PBL tutors (F=22.39, P=0.000. Other important predictors for tutoring skills were providing a relaxed class atmosphere and effective use of audiovisual aids in the lecture. Conclusion: Predicting the tutoring skills based on lecturing skills could have implications for recruiting tutors in PBL medical programs and for tutor training initiatives.

    Powell, Sarah R; Driver, Melissa K; Julian, Tyler E

    2015-01-01

    Students often misinterpret the equal sign (=) as operational instead of relational. Research indicates misinterpretation of the equal sign occurs because students receive relatively little exposure to equations that promote relational understanding of the equal sign. No study, however, has examined effects of nonstandard equations on the equation solving and equal-sign understanding of students with mathematics difficulty (MD). In the present study, second-grade students with MD (n = 51) were randomly assigned to standard equations tutoring, combined tutoring (standard and nonstandard equations), and no-tutoring control. Combined tutoring students demonstrated greater gains on equation-solving assessments and equal-sign tasks compared to the other two conditions. Standard tutoring students demonstrated improved skill on equation solving over control students, but combined tutoring students' performance gains were significantly larger. Results indicate that exposure to and practice with nonstandard equations positively influence student understanding of the equal sign. © Hammill Institute on Disabilities 2013.

    Full Text Available Problem statement: Web services are interface elements which allow applications to render functional services to requesting clients using open standard protocols. A lecture method combines both social association and urban processing as course design and delivery is termed as Interface Learning. Many Interface learning services is presenting through online. To make an online tutoring scheme more effective, the previous study used web services and application programs like instant messaging based on environments in which students reside. But the downside is that it is difficult to maintain the service request queues online. The services and data storage processes are inefficient. Approach: To overcome all the above issues, a Learning Software Component Model (LSCM framework is formed in the present study to build a component model based on communication services available on the network. In addition to this, the proposed software component modeled with Learning Object (LO aspects integrates the related sub hierarchical components with the main component object framework. Based on LSCM, training schedules are identified efficiently. Results: The proposed LSCM framework is experimented to show the performance improvement with the previous online tutoring scheme based on web services in terms of delivery report, maintenance of tutoring sessions and reliability. Conclusion: Compared to an existing online tutoring through web services, the proposed LSCM framework performance is 75% better in providing learning services to the providers.

    Full Text Available This article brings the analysis of a study—of a descriptive-analytical nature—about online tutoring, some of its characteristics and peculiarities as compared to face-to-face education. To this end it analyzes the results of an online questionnaire answered by 222 tutors pertaining to programs offered at Universidade Federal de São Carlos (UFSCar in partnership with Universidade Aberta do Brasil (UAB and Brazilian townships. The analysis focused on tutors’ characteristics (e.g., sex, education background and teaching experience, their work organization and activities, the division of labor (between tutors and teachers responsible for subjects, and their perceptions about the nature of tutoring and education at a distance (DE. This study is chiefly based on authors such as Lortie, Tardif, and Shulman—about face-to-face teaching—and Mill, Maggio, and Kenski—on distance education. The results of this study point to the predominance of female tutors, which resembles the makeup of the teaching body in face-to-face education at the lower levels, and indicate the respondents’ high levels of schooling and considerable face-to-face teaching experience. Despite the difficulties encountered by the tutors in this study, mainly due to their lack of experience in DE and varied technical problems, most of the tutors found it easy and pleasurable to work online. The dada also suggest that the tutors enjoyed comparative autonomy as regards actions associated with content transmission as well as actions related to (virtual classroom management. This autonomy may be the basis for the respondents’ perception that the online tutor, in the context under consideration, performs a genuine teaching function.

    An object-oriented multi-robotic graphic simulation environment is described in this paper. Object-oriented programming is used to model the physical objects of the robotic workcell in the form of software objects or classes. The virtual objects are defined to provide the user with a user-friendly interface including realistic graphic simulation and clarify the software architecture. The programming method of associating the task object with active object effectively increases the software reusability, maintainability and modifiability. Task level programming is also demonstrated through a multi-robot welding task that allows the user to concentrate on the most important aspects of the tasks. The multi-thread programming technique is used to simulate the interaction of multiple tasks. Finally, a virtual test is carried out in the graphic simulation environment to observe design and program errors and fix them before downloading the software to the real workcell.

    2010-03-01

    Concentrating solar power (CSP) technologies use large mirrors to concentrate sunlight and the thermal energy collected is converted to electricity. The CSP industry is growing rapidly and is expected to reach 25 GW globally by 2020. Cost target goals are for CSP technologies to produce electricity competitive with intermediate-load power generation (i.e., natural gas) by 2015 with 6 hours of thermal storage and competitive in carbon constrained base load power markets (i.e., coal) by 2020 with 12-17 hours of thermal storage. The solar field contributes more than 40% of the total cost of a parabolic trough plant and together the mirrors and receivers contribute more than 25% of the installed solar field cost. CSP systems cannot hit these targets without aggressive cost reductions and revolutionary performance improvements from technology advances. NREL's Advanced Materials task in the CSP Advanced R&D project performs research to develop low cost, high performance, durable solar reflector and high-temperature receiver materials to meet these needs. The Advanced Materials task leads the world in this research and the task's reliance on NREL's educational program will be discussed.

    Full Text Available This paper describes the interactive tutoring feedback model (ITF-model; Narciss, 2006; 2008, and how it can be applied to the design and evaluation of feedback strategies for digital learning environments. The ITF-model conceptualizes formative tutoring feedback as a multidimensional instructional activity that aims at contributing to the regulation of a learning process in order to help learners acquire or improve the competencies needed to master learning tasks. It integrates findings from systems theory with recommendations of prior research on interactive instruction and elaborated feedback, on task analyses, on error analyses, and on tutoring techniques. Based on this multi-dimensional view of formative tutoring feedback methodological implications for designing and investigating multiple effects of feedback under multiple individual and situational conditions are described.

    Full Text Available The study analyzed the conversational exchanges through which child tutors mediated literacy abilities and knowledge with young children in the framework of the project “From Child to Child: A Tutor-Child Literacy Program,” that is being conducted in Bueno s Aires, Argentina. The analysis considered the conversational moves deployed by both participants in the dyad, as well as the relationship between the tutor and the tutee. Likewise, it examined longitudinal variations in the interactions registered between the first tutoring sessions and the tutoring sessions that occurred after one year of the program. The tutoring sessions were video-taped and the different conversational moves deployed by the tutor and tutee were analyzed using an especially developed system of categories. Subsequently, the distribution of the categories of the tutee and tutor’s interactional moves in the corpus was analyzed quantitatively.Results showed significant longitudinal differences in the quantity of conversational moves: the tutors and the tutees increased their participation in the performance of the activities. The results demonstrated an increase in all the conversational moves the tutors utilized to promote the learning of the younger child tutee and a decrease in those conversational moves that do not promote learning.

    In this project, we have developed a sign language tutor that lets users learn isolated signs by watching recorded videos and by trying the same signs. The system records the user's video and analyses it. If the sign is recognized, both verbal and animated feedback is given to the user. The system is able to recognize complex signs that involve both hand gestures and head movements and expressions. Our performance tests yield a 99% recognition rate on signs involving only manual gestures and 85% recognition rate on signs that involve both manual and non manual components, such as head movement and facial expressions.

    Motivation and metacognition are strongly intertwined, with learners high in self-efficacy more likely to use a variety of self-regulatory learning strategies, as well as to persist longer on challenging tasks. The aim of the research was to improve the learner's focus on the process and experience of problem-solving while using an Intelligent Tutoring System (ITS) and including motivational and metacognitive feedback based on the learner's past states and experiences. An existing ITS, SQL-Tutor, was used with first-year undergraduates studying a database module. The study used two versions of SQL-Tutor: the Control group used a base version providing domain feedback and the Study group used an extended version that also provided motivational and metacognitive feedback. This paper summarises the pre- and post-process results. Comparisons between groups showed some differing trends both in learning outcomes and behaviour in favour of the Study group.

  9. Analysing tutor feedback to students: first steps towards constructing an electronic monitoring system

    Denise Whitelock

    2003-12-01

    Full Text Available Virtual Learning Environments provide the possibility of offering additional support to tutors, monitors and students in writing and grading essays and reports. They enable monitors to focus on the assignments that need most attention. This paper reports the findings from phase one of a feasibility study to assist the monitoring of student essays. It analyses tutor comments from electronically marked assignments and investigates how they match the mark awarded to each essay by the tutor. This involved carrying out a category analysis of the tutors' feedback to the students using Bales's 'interactional categories' as a theoretical basis. The advantage of this category system is that it distinguishes between task-orientated contributions, and the 'socio-emotive' element used by tutors to maintain student motivation. This reveals both how the tutor makes recommendations to improve the assignment content, and how they provide emotional support to students. Bales's analysis was presented to a group of tutors who felt an electronic feedback system based on this model would help them to get the right balance of responses to their students. These findings provide a modest start to designing a model of feedback for tutors of distance education students. Future work will entail refining these categories and testing this model with a larger sample from a different subject domain.

    2005-10-01

    Full Text Available In an effort to support the growing trend of the Java programming language and to promote web-based personalized education, the Java Intelligent Tutoring System (JITS was designed and developed. This tutoring system is unique in a number of ways. Most Intelligent Tutoring Systems require the teacher to author problems with corresponding solutions. JITS, on the other hand, requires the teacher to only supply the problem and problem specification. JITS is designed to "intelligently" examine the student's submitted code and determines appropriate feedback based on a number of factors such as JITS' cognitive model of the student, the student's skill level, and problem details. JITS is intended to be used by beginner programming students in their first year of College or University. This paper discusses the important aspects of the design and development of JITS, the qualitative methods and procedures, and findings. Research was conducted at the Sheridan Institute of Technology and Advanced Learning, Ontario, Canada.

    2017-01-26

    Modern hardware contains parallel execution resources that are well-suited for data-parallelism-vector units-and task parallelism-multicores. However, most work on parallel scheduling focuses on one type of hardware or the other. In this work, we present a scheduling framework that allows for a unified treatment of task- and data-parallelism. Our key insight is an abstraction, task blocks, that uniformly handles data-parallel iterations and task-parallel tasks, allowing them to be scheduled on vector units or executed independently as multicores. Our framework allows us to define schedulers that can dynamically select between executing task- blocks on vector units or multicores. We show that these schedulers are asymptotically optimal, and deliver the maximum amount of parallelism available in computation trees. To evaluate our schedulers, we develop program transformations that can convert mixed data- and task-parallel pro- grams into task block-based programs. Using a prototype instantiation of our scheduling framework, we show that, on an 8-core system, we can simultaneously exploit vector and multicore parallelism to achieve 14×-108× speedup over sequential baselines.

  14. Task Characterisation and Cross-Platform Programming Through System Identification

    Directory of Open Access Journals (Sweden)

    Roberto Iglesias

    2008-11-01

    Full Text Available Developing robust and reliable control code for autonomous mobile robots is difficult, because the interaction between a physical robot and the environment is highly complex, it is subject to noise and variation, and therefore partly unpredictable. This means that to date it is not possible to predict robot behaviour, based on theoretical models. Instead, current methods to develop robot control code still require a substantial trial-and-error component to the software design process. Such iterative refinement could be reduced, we argue, if a more profound theoretical understanding of robot-environment interaction existed. In this paper, we therefore present a modelling method that generates a faithful model of a robot's interaction with its environment, based on data logged while observing a physical robot's behaviour. Because this modelling method - nonlinear modelling using polynomials - is commonly used in the engineering discipline of system identification, we refer to it here as "robot identification". We show in this paper that using robot identification to obtain a computer model of robot environment interaction offers several distinct advantages:
    1. Very compact representations (one-line programs of the robot control program are generated
    2.The model can be analysed, for example through sensitivity analysis, leading to a better understanding of the essential parameters underlying the robot's behaviour, and
    3. The generated, compact robot code can be used for cross-platform robot programming, allowing fast transfer of robot code from one type of robot to another.
    We demonstrate these points through experiments with a Magellan Pro and a Nomad 200 mobile robot.

    Takahashi, Yuzo

    2008-03-01

    The author of this article attended the International PBL Workshop in Kaohsiung Medical University in 2007 as an international tutor. Based on his personal experiences in the workshop and at his own medical school, he finds there are frequent problems in PBL programs related to the difficulty in providing expert tutors. Students in PBL tutorials may fear they are unable to get sufficient guidance from tutors in terms of learning the issues they should research; moreover, PBL case writers fear their cases are less effective, because non-expert tutors may misdirect students in the step 1 tutorial discussion. The author proposes that combining standard problem-based learning (PBL) methods with elements of task-based learning (TBL) can be effective at addressing both of these problems. The TBL method he proposes involves providing students with an additional sheet at the end of PBL tutorials. This sheet is written by the case writer and details key learning issues, questions and perspectives the students should investigate during their research process. This reduces the need to have expert tutors who know the full range of facts about the case, and leaves students feeling supported and less concerned they will miss important learning issues.

    We have developed computer-assisted speech and language tutors for deaf, hard of hearing, and autistic children. Our language-training program utilizes our computer-animated talking head, Baldi, as the conversational agent, who guides students through a variety of exercises designed to teach vocabulary and grammer, to improve speech articulation, and to develop linguistic and phonological awareness. Baldi is an accurate three-dimensional animated talking head appropriately aligned with either synthesized or natural speech. Baldi has a tongue and palate, which can be displayed by making his skin transparent. Two specific language-training programs have been evaluated to determine if they improve word learning and speech articulation. The results indicate that the programs are effective in teaching receptive and productive language. Advantages of utilizing a computer-animated agent as a language tutor are the popularity of computers and embodied conversational agents with autistic kids, the perpetual availability of the program, and individualized instruction. Students enjoy working with Baldi because he offers extreme patience, he doesn't become angry, tired, or bored, and he is in effect a perpetual teaching machine. The results indicate that the psychology and technology of Baldi holds great promise in language learning and speech therapy. [Work supported by NSF Grant Nos.

    1994-11-01

    This report summarizes the Advanced Diesel Engine Component Development (ADECD) Program to develop and demonstrate critical technology needed to advance the heavy-duty low heat rejection engine concept. Major development activities reported are the design, analysis, and fabrication of monolithic ceramic components; vapor phase and solid film lubrication; electrohydraulic valve actuation; and high pressure common rail injection. An advanced single cylinder test bed was fabricated as a laboratory tool in studying these advanced technologies. This test bed simulates the reciprocator for a system having no cooling system, turbo compounding, Rankine bottoming cycle, common rail injection, and variable valve actuation to achieve fuel consumption of 160 g/kW-hr (.26 lb/hp-hr). The advanced concepts were successfully integrated into the test engine. All ceramic components met their functional and reliability requirements. The firedeck, cast-in-place ports, valves, valve guides, piston cap, and piston ring were made from silicon nitride. Breakthroughs required to implement a 'ceramic' engine included the fabrication of air-gap cylinder heads, elimination of compression gaskets, machining of ceramic valve seats within the ceramic firedeck, fabrication of cast-in-place ceramic port liners, implementation of vapor phase lubrication, and elimination of the engine coolant system. Silicon nitride valves were successfully developed to meet several production abuse test requirements and incorporated into the test bed with a ceramic valve guide and solid film lubrication. The ADECD cylinder head features ceramic port shields to increase insulation and exhaust energy recovery. The combustion chamber includes a ceramic firedeck and piston cap. The tribological challenge posed by top ring reversal temperatures of 550 C was met through the development of vapor phase lubrication using tricresyl phosphate at the ring-liner interface.

    2004-04-01

    In the antisaccade task subjects are required to suppress the reflexive tendency to look at a peripherally presented stimulus and to perform a saccade in the opposite direction instead. The present studies aimed at investigating the inhibitory mechanisms responsible for successful performance in this task, testing a hypothesis of parallel programming of exogenous and endogenous components: A reflexive saccade to the stimulus is automatically programmed and competes with the concurrently established voluntary programme to look in the opposite direction. The experiments followed the logic of selectively manipulating the speed of processing of these components and testing the prediction that a selective slowing of the exogenous component should result in a reduced error rate in this task, while a selective slowing of the endogenous component should have the opposite effect. The results provide evidence for the hypothesis of parallel programming and are discussed in the context of alternative accounts of antisaccade performance.

  2. Peer Tutoring as a Remedial Measure for Slow Learners in a Medical School

    Directory of Open Access Journals (Sweden)

    Ray (Arora Suranjana

    2015-01-01

    Full Text Available Background: A Slow Learner (SL is one who has the ability to learn necessary academic skills but at a rate and depth below average of the same age peers. Aims: To identify SL we have to judge them not just by their grade level, but by the fact that they master skills slowly, have difficulty following multistep directives, live in the present and do not have long term goals. The remedial measures for these SL were repetition, peer tutoring, enhancing their self-esteem and improve confidence. With correct monitoring, support and feedback from a teacher facilitator peer tutoring can provide deeper learning, reduce dropout, and improve social behavior. Objective: The aim was to identify SL and to peer tutor them. Material and Methods: In a group of 106 students in the first year of MBBS in a college in Mauritius 20 students were identified as SL, out of the other 86 students 2 to 3 students were selected as peer tutors. The sample size on which the questionnaire was used to determine slow learners were 106 out of which 20 were found to be slow learners. The peer tutors were selected among the 106 students. The facilitator trained the tutors. Conclusion: In our Institute we found an alarming 15-18% of SL. The SL responded positively to the peer tutoring and a significant number improved their academic performance. Peer tutoring has significant cognitive gains for both tutor and tutees. Peer tutoring improves selfconfidence, academic achievement, improves their attitude towards the subject matter and encourages greater persistence in completing tasks. Identifying SL has many pitfalls as we should confirm that they are not 'reluctant' or 'struggling' learners but SL.

    Parent tutoring has been successfully used to increase children's oral reading fluency. However, commonly used procedures pose a challenge for parents who are not proficient in reading or who speak English as a second language. A taped reading program that included listening passage preview, repeated reading, and performance feedback was developed…

    Full Text Available In this paper we report on a longitudinal study of a Leonardo da Vinci program regarding the application of a Computer Based Learning environment in three EU countries, Greece, Germany, and Holland. The `` Orestis''CD-ROM was a multimedia CBL environment aimed at teaching young offenders the basic and advanced skills for the use and maintenance of a photo-copy shop. The complete project consisted of three phases: construction of the CD-ROM, application of the instructional methodology in the participating countries and evaluation of the outcome. In this paper we firstly clarify the notion of CBL environments, in comparison to multimedia and distance learning ones, and then we provide some theoretical background on these environments. The main research question we tried to answer was whether the application of the environment under real circumstances could perform adequately without the presence of a domain expert as a ``teacher'', but rely on a ``tutor'' who had five main tasks to perform during the instructional phase, as described in the paper. In order to answer this question, we designed and constructed the aforementioned integrated CBL environment and, in addition to this, an instructional methodology in order to apply it effectivelly in the participating countries. The application of the environment by the partners showed our hypothesis about the tutor to be correct, moreover we elicited results about the different user groups that worked with the environment and their performance under different circumstances. We studied also the combination of CBL training and real practice in real environments, among some other issues concerning the application of CBL environments in general, and we provide some statistical facts as observed and reported during the two pilot studies and the five applications of the environment in the three participating European countries. We conclude by arguing that the tutor, as described in this paper, performs more

    Full Text Available Abstract Background Clinical contact in the early curriculum and workplace learning with active tutorship are important parts of modern medical education. In a previously published study, we found that medical students' tutors experienced a heavier workload, less reasonable demands and less encouragement, than students. The aim of this interview study was to further illuminate physicians' experiences as clinical tutors. Methods Twelve tutors in the Early Professional Contact course were interviewed. In the explorative interviews, they were asked to reflect upon their experiences of working as tutors in this course. Systematic text condensation was used as the analysis method. Results In the analysis, five main themes of physicians' experiences as clinical tutors in the medical education emerged: (a Pleasure and stimulation. Informants appreciated tutorship and meeting both students and fellow tutors, (b Disappointment and stagnation. Occasionally, tutors were frustrated and expressed negative feelings, (c Demands and duty. Informants articulated an ambition to give students their best; a desire to provide better medical education but also a duty to meet demands of the course management, (d Impact of workplace relations. Tutoring was made easier when the clinic's management provided active support and colleagues accepted students at the clinic, and (e Multitasking difficulties. Combining several duties with those of a tutorship was often reported as difficult. Conclusions It is important that tutors' tasks are given adequate time, support and preparation. Accordingly, it appears highly important to avoid multitasking and too heavy a workload among tutors in order to facilitate tutoring. A crucial factor is acceptance and active organizational support from the clinic's management. This implies that tutoring by workplace learning in medical education should play an integrated and accepted role in the healthcare system.

    1994-11-01

    St. Francis Health Care Centre in Green Springs, OH, decided in 1991 to enlist local merchants in a program in rehabilitative medicine. The program, named for Green Springs's main street, is "Broadway: A Route Home." Broadway is a program for persons who, because of severe illness or injury, require extended rehabilitation. Along with care for continuing physical or cognitive problems, such patients often need help in performing tasks--buying groceries, cashing a check, renting a video--that most people take for granted. Under the Broadway program patients can practice these tasks safely in shops, restaurants, and theaters in Green Springs and other nearby communities. Later, escorted by therapists, some patients journey to larger cities and, finally, to their own communities, to exercise everyday skills.

    This study compared the self-rated with student-rated teaching styles of PBL tutors. We also examined the relationship between teaching styles of tutors' and students' evaluation of tutor effectiveness in tutorials. The study included 48 tutors and 276 medical students. Tutors, and students' were given a teaching style inventory with a 5-point scale consisting of 21 items that comprise four domains of teaching styles (facilitative, collaborative, suggestive and assertive). In addition, quantitative and qualitative evaluations of tutor effectiveness by students were analyzed. Tutors perceived themselves in the facilitative-collaborative end of the spectrum of styles In contrast, students perceived tutors as less 'facilitative-collaborative' and more 'suggestive-assertive' than tutors self-ratings (p teaching styles. However, other tutor attributes such as establishing rapport with students, providing academic help for them and having content expertise were considered important criteria of an effective tutor. We conclude that there is a mismatch between students' and tutors' perceptions about teaching styles of tutor. Tutor attributes other than teaching styles are important determinants of an effective tutor.

    The Contractor Information Meeting (October 14 to 17, 1979) was part of the FY-1979 effort of Task 4 of the Waste Isolation Safety Assessment Program (WISAP): Sorption/Desorption Analysis. The objectives of this task are to: evaluate sorption/desorption measurement methods and develop a standardized measurement procedure; produce a generic data bank of nuclide-geologic interactions using a wide variety of geologic media and groundwaters; perform statistical analysis and synthesis of these data; perform validation studies to compare short-term laboratory studies to long-term in situ behavior; develop a fundamental understanding of sorption/desorption processes; produce x-ray and gamma-emitting isotopes suitable for the study of actinides at tracer concentrations; disseminate resulting information to the international technical community; and provide input data support for repository safety assessment. Conference participants included those subcontracted to WISAP Task 4, representatives and independent subcontractors to the Office of Nuclear Waste Isolation, representatives from other waste disposal programs, and experts in the area of waste/geologic media interaction. Since the meeting, WISAP has been divided into two programs: Assessment of Effectiveness of Geologic Isolation Systems (AEGIS) (modeling efforts) and Waste/Rock Interactions Technology (WRIT) (experimental work). The WRIT program encompasses the work conducted under Task 4. This report contains the information presented at the Task 4, Third Contractor Information Meeting. Technical Reports from the subcontractors, as well as Pacific Northwest Laboratory (PNL), are provided along with transcripts of the question-and-answer sessions. The agenda and abstracts of the presentations are also included. Appendix A is a list of the participants.

    Twenty-nine pediatric residency training programs responded to a survey with detailed descriptions of the scheduled rotations before and after the Report of the Task Force on Pediatric Education. This survey documented some changes in the overall structure of residency programming in that all programs demand 3 years of general pediatric training. Little if any changes were noted in the traditional emphasis on inpatient and neonatal training. Some changes in content area have been noted, namely a modest increase in the experiences in adolescent medicine. The survey failed to demonstrate any trend indicating increased emphasis on training experiences in the "new morbidity."

Evaluation of trainers’ views about STP is linked with their responsibilities, and is placed within the context of the need for a more structural or planned approach to training. Method: This research was conducted in the Community of Madrid, by means of four Focal-group. Trainers were selected from primary care and hospitals where STP occurs. Results: Participants discussed about the academic and medical profile of the tutor, the characteristics of the selection and accreditation process of trainers, and about responsibilities, tasks and recognition of the tutorial. Conclusions: A discordant between the theoretical and practical values assigned to the teaching staff has been clearly identified. The later was determined by its dependence respect to the clinical practice, the paucity of resources, and the lack of recognition of their role in the teaching establishment. Clearance-cut with objective nomination process, some independence of training in the clinical setting, emphasize the role of the Teaching Commissions, arrange timing to the training program, and the recognition in the professional career were pointed as possible solutions.

    Full Text Available Accurately identifying mild cognitive impairment (MCI individuals who will progress to Alzheimer's disease (AD is very important for making early interventions. Many classification methods focus on integrating multiple imaging modalities such as magnetic resonance imaging (MRI and fluorodeoxyglucose positron emission tomography (FDG-PET. However, the main challenge for MCI classification using multiple imaging modalities is the existence of a lot of missing data in many subjects. For example, in the Alzheimer's Disease Neuroimaging Initiative (ADNI study, almost half of the subjects do not have PET images. In this paper, we propose a new and flexible binary classification method, namely Multi-task Linear Programming Discriminant (MLPD analysis, for the incomplete multi-source feature learning. Specifically, we decompose the classification problem into different classification tasks, i.e., one for each combination of available data sources. To solve all different classification tasks jointly, our proposed MLPD method links them together by constraining them to achieve the similar estimated mean difference between the two classes (under classification for those shared features. Compared with the state-of-the-art incomplete Multi-Source Feature (iMSF learning method, instead of constraining different classification tasks to choose a common feature subset for those shared features, MLPD can flexibly and adaptively choose different feature subsets for different classification tasks. Furthermore, our proposed MLPD method can be efficiently implemented by linear programming. To validate our MLPD method, we perform experiments on the ADNI baseline dataset with the incomplete MRI and PET images from 167 progressive MCI (pMCI subjects and 226 stable MCI (sMCI subjects.

    1988-01-01

    A large number of Intelligent Tutoring Systems (ITSs) have been built since they were first proposed in the early 1970's. Research conducted on the use of the best of these systems has demonstrated their effectiveness in tutoring in selected domains. A prototype ITS for tutoring students in the use of CLIPS language: CLIPSIT (CLIPS Intelligent Tutor) was developed. For an ITS to be widely accepted, not only must it be effective, flexible, and very responsive, it must also be capable of functioning on readily available computers. While most ITSs have been developed on powerful workstations, CLIPSIT is designed for use on the IBM PC/XT/AT personal computer family (and their clones). There are many issues to consider when developing an ITS on a personal computer such as the teaching strategy, user interface, knowledge representation, and program design methodology. Based on experiences in developing CLIPSIT, results on how to address some of these issues are reported and approaches are suggested for maintaining a powerful learning environment while delivering robust performance within the speed and memory constraints of the personal computer.

  10. The subjective experience of collaboration in interprofessional tutor teams: A qualitative study

    Directory of Open Access Journals (Sweden)

    Weber, Tobias

    2016-04-01

    Full Text Available Aim: The Center for Interprofessional Training in Medicine at the Faculty of Medicine Carl Gustav Carus at the Technische Universität Dresden, Germany, has offered courses covering interprofessional material since the winter semester 2014/15. The unusual feature of these courses is that they are co-taught by peer tutors from medicine and nursing. This study investigates the subjective experiences of these tutors during the collaborative preparation and teaching of these tutorials with the aim of identifying the effects of equal participation in the perceptions and assessments of the other professional group.Method: Semi-structured, guideline-based interviews were held with six randomly selected tutors. The interviews were analyzed using structuring content analysis.Results: The results show that collaborative work led to reflection, mostly by the university student tutors, on the attitudes held. However, the co-tutors from each professional group were perceived to different degrees as being representative of those in their profession. Asked to master a shared assignment in a non-clinical context, the members of the different professional groups met on equal footing, even if the medical students had already gathered more teaching experience and thus mostly assumed a mentoring role over the course of working on and realizing the teaching units. The nursing tutors were primarily focused on their role as tutor. Both professional groups emphasized that prior to the collaboration they had an insufficient or no idea about the theoretical knowledge or practical skills of the other professional group. Overall, the project was rated as beneficial, and interprofessional education was endorsed.Conclusion: In the discussion, recommendations based on the insights are made for joint tutor training of both professional groups. According to these recommendations, harmonizing the teaching abilities of all tutors is essential to ensure equality during cooperation

  12. Programming of left hand exploits task set but that of right hand depends on recent history.

    2017-07-01

    There are many differences between the left hand and the right hand. But it is not clear if there is a difference in programming between left hand and right hand when the hands perform the same movement. In current study, we carried out two experiments to investigate whether the programming of two hands was equivalent or they exploited different strategies. In the first experiment, participants were required to use one hand to grasp an object with visual feedback or to point to the center of one object without visual feedback on alternate trials, or to grasp an object without visual feedback and to point the center of one object with visual feedback on alternating trials. They then performed the tasks with the other hand. The result was that previous pointing task affected current grasping when it was performed by the left hand, but not the right hand. In experiment 2, we studied if the programming of the left (or right) hand would be affected by the pointing task performed on the previous trial not only by the same hand, but also by the right (or left) hand. Participants pointed and grasped the objects alternately with two hands. The result was similar with Experiment 1, i.e., left-hand grasping was affected by right-hand pointing, whereas right-hand grasping was immune from the interference from left hand. Taken together, the results suggest that when open- and closed-loop trials are interleaved, motor programming of grasping with the right hand was affected by the nature of the online feedback on the previous trial only if it was a grasping trial, suggesting that the trial-to-trial transfer depends on sensorimotor memory and not on task set. In contrast, motor programming of grasping with the left hand can use information about the nature of the online feedback on the previous trial to specify the parameters of the movement, even when the type of movement that occurred was quite different (i.e., pointing) and was performed with the right hand. This suggests that

  13. Two approaches to physics tutoring

    Science.gov (United States)

    Solomaniuck, Tania

    One in two first-year students at science or biomedical faculties fail in basic subjects such as mathematics, chemistry or physics. Course-specific tutoring is one of the available means for improving their performance. In the present research, two tutoring models are developed. Both incorporate independent learning, but from different perspectives and priorities. A pragmatic tutoring approach. The first part of the thesis describes the search process for an optimal course-specific tutoring strategy for a standard first-year physics course in life sciences curricula. After a number of empirical research rounds, a pragmatic compromise emerged as the most suitable form of tutoring. The approach is characterised by: (1) priority to questions from students; (2) a high degree of interactivity with the tutor and among students; (3) due consideration to the number of questions to be dealt with and the depth in which they should be discussed. Most students participating in the tutoring sessions expressed their satisfaction and performed sufficiently well in their exams. However, there was still a problem: the students' insight into the course material was restricted to first-order processing of the syllabus. While this would be satisfactory in non-scientific study programmes, it is deemed insufficient in programmes where deeper insight is required in order that students be able to deal adequately with new conceptual questions or problems. In-depth tutoring. In science programmes, the core objective is for students to acquire in-depth knowledge. Therefore, science educators are designing and studying teaching methods that are geared not only to the acquisition of in-depth knowledge as such, but also to the motivation of students to take a more in-depth approach to learning. Some of the crucial notions in their research are: the extent to which the course content ties in with students' prior knowledge, problem-setting strategies and concept-context linking. 'In

    1997-02-01

    The computer-based tutoring of visual concepts such as radiological images is a largely unexplored area. A review of the literature highlights limited use of computers as a means of radiological education, with the majority of systems being little more than hypermedia prototypes, on-line teaching files, and passive CD-Roms. Very few of the systems discussed in the research literature draw on the work from cognitive science and educational psychology for tutoring visual concepts. This thesis details and evaluates a method for indexing and retrieving images from large image databases via a cognitively informed graphical representation of visual concepts. This representation is derived using Multiple Correspondence Analysis from a statistical analysis of features present in the images. It is intended that this representation be used to assist in the computer based teaching of any discipline that requires the tutoring of visual concepts. The domain used as a test bed for this research is Magnetic Resonance Imaging in neuroradiology. Tutoring the interpretation of MR scans of the head represents a real practical problem due to the inherent complexity of the brain and variations in tissue contrast within image sequence and disease/pathology. The literature of concept categorisation and representation is critically reviewed to inform the design of a graphical representation of a concept (a pathology in the application domain). A specification for the design of an explicit representation of visual concepts is drawn from this literature review, together with methods of tutoring based around this model. A methodology for producing this representation is described, and implemented in the development of an overview plot for the concept of a disease of the brain, with associated statistical measures derived and operationalised for typicality and similarity of cases within a disease. These measures are precursors to the development of computer based tutoring strategies for image

    The Joint Task Force on Undergraduate Physics Programs (JTUPP) was formed in response to growing awareness in the physics community that physics majors pursue a wide range of careers after graduation, with very few ending up in academia. The task force is charged with identifying the skills and knowledge that undergraduate physics degree holders should possess to be well prepared for a diverse set of careers, and providing guidance for physicists considering revising the undergraduate curriculum to improve the education of a diverse student population. Task force members represent large and small universities, professional societies, and industry, and have expertise in a broad range of areas including entrepreneurship, physics education research and systemic change in education. We reviewed employment data, surveys of employers, and reports generated by other disciplines. We also met with physicists in selected industries to get their views on the strengths and weaknesses of physics graduates, commissioned a series of interviews with recent physics graduates employed in the private sector, and identified exemplary programs that ensure that all of their students are well prepared to pursue a wide range of career paths. The findings and recommendations will be summarized.

    Mumford, Thomas J.

    The purpose of this study was to investigate the effects of Student Support Services peer tutoring on rural community college students' success in an Anatomy and Physiology class as measured changes in self-reported learning and study strategies, the final grade in Anatomy and Physiology class, and persistence/retention in the following semesters. A secondary goal was to assess the relative merits of two training methods: standard peer tutoring and standard peer tutoring plus introduction to attribution theory. This Anatomy and Physiology class typically has a failure rate of 50%. The federal government annually funds more than 700 Student Support Services (SSS) grants and 162 Health Career Opportunities Programs (HCOP). Nearly 94% of these SSS programs included a tutoring component, and 84% of these programs use peer tutoring. Peer tutors were randomly assigned to one of the treatment conditions and students were randomly assigned to one of the two treatment conditions. There were 31 students in the attribution condition and 28 students in the standard condition. Students were required to have a minimum of 10 hours of tutoring to be included in the analysis. Each tutored student was yoked to a control student who had not sought peer tutoring assistance. Participants were matched for age, marital status, number of adults in the family, number of children in the family and incoming academic skills (CPT Reading Test Results), financial status, and race. The results support peer tutoring as an effective method of increasing student success. The findings support the use of attribution training for tutors as a theoretical base of intervention. Students tutored by attribution trained tutors scored significantly higher on LASSI, had higher Anatomy and Physiology grades, and returned to college at a higher rate than their yoked controls. Standard trained tutors scored significantly higher on the LASSI Test Taking subscale and returned to college at a higher rate than their

    2009-06-01

    Full Text Available Abstract Background Medical programmes that implement problem-based learning (PBL face several challenges when introducing this innovative learning method. PBL relies on small group as the foundation of study, and tutors facilitate learning by guiding the process rather than teaching the group. One of the major challenges is the use of strategies to assess students working in small groups. Self-, peer- and tutor-assessment are integral part of PBL tutorials and they're not easy to perform, especially for non experienced students and tutors. The undergraduate PBL medical programme was introduced in 2003, and after two years the curriculum committee decided to evaluate the tutorial assessment in the new program. Methods A random group of ten students, out of a cohort of sixty, and ten tutors (out of eighteen were selected for semi-structured interviews. The social representations' theory was used to explore how the students and tutors made sense of "assessment in tutorials". The data were content analyzed using software for qualitative and quantitative processing of text according to lexicological distribution patterns. Results Even though students and tutors are aware of the broader purpose of assessment, they felt that they were not enough trained and confident to the tutorial assessment. Assigning numbers to complex behaviors on a regular basis, as in tutorials, is counter productive to cooperative group learning and self assessment. Tutors believe that students are immature and not able to assess themselves and tutors. Students believe that good grades are closely related to good oral presentation skills and also showed a corporative attitude among themselves (protecting each other from poor grades. Conclusion Faculty training on PBL tutorials' assessment process and a systematic strategy to evaluate new programs is absolutely necessary to review and correct directions. It is envisaged that planners can make better-informed decisions about

    2016-03-01

    The content of undergraduate physics programs has not changed appreciably in 50 years, however, the jobs our students take have changed dramatically. Preparing students for careers they are likely to encounter requires physics programs to rethink and in some cases retool to provide an education that will not only educate an individual in the habits of mind and keen sense of how to solve complex technical problems, but also what related skills they will need to be effective in those careers. Do you teach your student how to read or create a budget? How about dealing with a low-performing member of an R&D team? This talk will explore driving forces behind this report, potential implications for physics departments, and practical steps faculty members can take to continue to consider improvements in experiences for our students. This work is supported in part by the National Science Foundation (NSF-1540570).

    Full Text Available Modern undergraduates join science and engineering courses with poorer mathematical background than most contemporaries of the current faculty had when they were freshers. The problem is very acute in the United Kingdom but more and more countries adopt less resource intensive models of teaching and the problem spreads. University tutors and lecturers spend more and more time covering the basics. However, most of them still rely on traditional methods of delivery which presuppose that learners have a good memory and considerable time to practice, so that they can memorize disjointed facts and discover for themselves various connections between the underlying concepts. These suppositions are particularly unrealistic when dealing with a large number of undergraduates who are ordinary learners with limited mathematics background. The first author has developed a teaching system that allows such adult learners achieve relatively deep learning of mathematics – and remarkably quickly – through a teacher-guided (often called Socratic dialog, which aims at the frequent reinforcement of basic mathematical abstractions through Eulerian sequencing. These ideas have been applied to create a prototype of a Cognitive Mathematics Tutoring System aimed at teaching basic mathematics to University freshers., an electronic Personal Algebra and Calculus Tutor (e- PACT.

    Full Text Available This paper considers professional development in a context that is familiar and problematic to teaching teams in tertiary education everywhere, that of delivering online programmes with an ever-decreasing complement of staff. The Teaching Qualification Further Education (TQFE teaching team at University of Dundee confronted the reality of reduced staff numbers by centralising tutoring and support for programme participants. The new system involves standardising tutoring as far as possible through generic email, blog and microblog accounts, all badged “TQFE-Tutor” and staffed on a roster basis. Once the new “rules of engagement” via TQFE-Tutor were in place, it became clear that in addition to benefits in terms of student support, there were other unintended positive consequences: opportunities for informal professional development for staff and the promotion of effective team working. The experience of collective tutoring has facilitated collaboration on a range of innovations within online learning. This paper describes the evolution of the TQFE-Tutor innovation and reports upon a small scale study which was carried out to gather the views of the tutor team working with TQFE-Tutor. The authors conclude that the centralisation of communication and tutoring on the TQFE programme has been highly beneficial in terms of professional development for the team.

    2015-06-01

    Full Text Available The key role of the tutor in problem-based learning (PBL is to help students become selfregulated learners. Tutors need training to acquire the necessary facilitating skills for this task. The aim of this article is to describe and discuss how PBL tutor training is currently arranged at four universities in Sweden: Linköping University, Lund Medical Faculty, Uppsala Medical School and Örebro School of Medicine. Moreover, we seek to analyse how the content and format of the tutor training courses correspond to the desired skills and competencies for PBL tutors described in the literature. We draw especially on work coming out of three pioneering universities for PBL: McMaster University, Canada; Maastricht University, The Netherlands; and Linköping University, Sweden. One aim has been to construct a framework for analysis that uses categories specifying the knowledge base, capabilities and skills to support students’ learning processes which characterise the full-fledged PBL tutor. For this framework, we have used the following categories: Knowledge of PBL and pedagogical theories, Personal traits, Student-centeredness, Ability to handle group processes, and Subject knowledge. We collected descriptions of the course design and content from the four universities, and assessed to what extent these categories were represented within the courses. Our results show that all categories inform the course content at all four universities, though the design varies between courses. In summary, we show that the four PBL tutor training courses are all designed to enable participants to experience PBL first-hand both as members of a tutorial group and as tutors. They all also include a theoretical base and offer opportunities for discussion and reflection with peers; however, there are some differences in design between the courses. According to participants, all four courses provide good preparation for the tutor role. Yet, we see a need for the

    IMPORTANCE Clinical trials suggest that higher doses of task-oriented training are superior to current clinical practice for patients with stroke with upper extremity motor deficits. OBJECTIVE To compare the efficacy of a structured, task-oriented motor training program vs usual and customary occupational therapy (UCC) during stroke rehabilitation. DESIGN, SETTING, AND PARTICIPANTS Phase 3, pragmatic, single-blind randomized trial among 361 participants with moderate motor impairment recruited from 7 US hospitals over 44 months, treated in the outpatient setting from June 2009 to March 2014. INTERVENTIONS Structured, task-oriented upper extremity training (Accelerated Skill Acquisition Program[ASAP]; n = 119); dose-equivalent occupational therapy (DEUCC; n = 120); or monitoring-only occupational therapy (UCC; n = 122). The DEUCC group was prescribed 30 one-hour sessions over 10 weeks; the UCC group was only monitored, without specification of dose. MAIN OUTCOMES AND MEASURES The primary outcome was 12-month change in log-transformed Wolf Motor Function Test time score (WMFT, consisting of a mean of 15 timed arm movements and hand dexterity tasks). Secondary outcomes were change in WMFT time score (minimal clinically important difference [MCID] = 19 seconds) and proportion of patients improving ≥25 points on the Stroke Impact Scale (SIS) hand function score (MCID = 17.8 points). RESULTS Among the 361 randomized patients (mean age, 60.7 years; 56% men; 42% African American; mean time since stroke onset, 46 days), 304 (84%) completed the 12-month primary outcome assessment; in intention-to-treat analysis, mean group change scores (log WMFT, baseline to 12 months) were, for the ASAP group, 2.2 to 1.4 (difference, 0.82); DEUCC group, 2.0 to 1.2 (difference, 0.84); and UCC group, 2.1 to 1.4 (difference, 0.75), with no significant between-group differences (ASAP vs DEUCC:0.14; 95% CI, −0.05 to 0.33; P = .16; ASAP vs UCC: −0.01; 95% CI, −0.22 to 0.21; P = .94; and

    Both fish oil supplementation and physical exercise are able to induce benefits to mental health by providing an improvement in cognitive performance and enhancing neuroplasticity and protection against neurological lesions. The aim of the present study was to investigate the cognitive effects in rats of the: (1) a diary and prolonged fish oil supplementation (85 mg/kg/day) initiated from prenatal period to the midlife (300 day/old); (2) moderate physical exercise in treadmill initiated from adolescent period to midlife and (3) association of fish oil supplementation and moderate physical exercise protocol during the same period. Animals were submitted to the habituation in the open-field, object recognition and to the plus-maze discriminative avoidance tasks. Our results demonstrated that a diary and prolonged fish oil supplementation can facilitate the persistence of the long-term habituation and recognition memories without, however, affecting the discriminative avoidance memory. Conversely, although the program of physical exercise exerted no effects on habituation or objects recognition, it was able to potentiate the persistence of the discriminative avoidance memory. Such promnestic effects (induced by both fish oil supplementation and physical exercise) were not accompanied by alterations in emotionality or locomotor activity. Our findings suggest that fish oil supplementation, initiated from prenatal period to midlife, and physical exercise program applied throughout the life induced distinctly a better cognitive performance.

    Professional identity is a key issue spanning the entirety of teachers' career development. Despite the abundance of existing research examining professional identity, its link with occupation-related behavior at the primary career stage (i.e., GPA in preservice education) and the potential process that underlies this association is still not fully understood. This study explored the professional identity of Chinese preservice teachers, and its links with task value belief, intrinsic learning motivation, extrinsic learning motivation, and performance in the education program. Grade-point average (GPA) of courses (both subject and pedagogy courses) was examined as an indicator of performance, and questionnaires were used to measure the remaining variables. Data from 606 preservice teachers in the first 3 years of a teacher-training program indicated that: (1) variables in this research were all significantly correlated with each other, except the correlation between intrinsic learning motivation and program performance; (2) professional identity was positively linked to task value belief, intrinsic and extrinsic learning motivations, and program performance in a structural equation model (SEM); (3) task value belief was positively linked to intrinsic and extrinsic learning motivation; (4) higher extrinsic (but not intrinsic) learning motivation was associated with increased program performance; and (5) task value belief and extrinsic learning motivation were significant mediators in the model.

    [Purpose] The aim of this study was to investigate the effects of a task-specific exercise program based on motor learning on balance ability and strength of the lower extremity in the elderly with/without falling experiences. [Subjects and Methods] Individuals who had experiences of falling over 2 times within the past 6 months were included in the falling group. The task-specific exercise program consisted of 3 stages (weeks 1–2, 3–4, and 5–6) and was conducted according to the level of difficulty in this study. [Results] The scores of the Korean version of the Activities-Specific Balance Confidence Scale and Performance-Oriented Mobility Assessment were significantly changed in both the falling group and non-falling group after the task-specific exercise program. In comparisons between the falling group and non-falling group, there were also significant differences in the Korean version of the Activities-Specific Balance Confidence Scale and muscle strength of the semitendinosus and gastrocnemius. [Conclusion] The task-specific exercise program has a positive effect on balance ability and muscle strength related to falls in the elderly. PMID:25435679

    2016-01-01

    Full Text Available The conducted investigation has included monitoring of the provision of educational services in a remote mode – distance-learning format for adult students at Moscow Business School (MBS. It is aimed at finding best approaches for increasing a degree of “reaching” every student. The problem is that some people, including potential candidates for distance-learning programs, blame distance education for the lack of communication with teacher/tutor. They say that distance learning does not allow applying the principles of customization to it; for some of them there is no difference between E-learning and distance learning. The results of this action research show rather clearly that there are ways in the framework of distance education to use an individual approach for each of the students by the tutors. Some types of intercommunication with students in written form could be rather exhausting ones, but others could be successfully carried out by a creative tutor

    Shamir, Adina; Zion, Michal; Spector Levi, Ornit

    2008-08-01

    The main objective of the study reported was to explore the effect on young children's critical thinking of a peer-tutoring training embedded with the metacognitive processes required for problem-based learning and, consequently, for critical thinking. The sample consisted of 90 first- and third-grade pupils (45 pairs) randomly assigned to the experimental or control group. The experimental tutors received the Peer Mediation training, an intervention containing embedded metacognitive processes. The control children received a general preparation for peer-assisted learning. Following their respective preparations, all the children participated in a peer-tutoring condition, videotaped for 25 min and subsequently analyzed with an adaptation of the Newman et al. (Interpers Comput Technol 3(2):56-77, 1995) content analysis instrument. Analysis of the discourse conducted during the tutoring session indicated that the tutors and tutees in the experimental groups exhibited greater depth of critical thinking, demonstrated in the higher Quality of Discourse Ratio calculated, than did the tutors and tutees in the control group. The findings supported previous results showing the efficacy of the Peer Mediation for Young Children mediation-training program, with its embedded metacognitive competencies, for reinforcing young children's higher-order thinking. Implications for educators are discussed.

    We examined the effects of a tutoring package (verbal modeling, prompts, and contingent praise/ Chinese conversations with the tutor) on the performance of a college student's Mandarin Chinese pronunciation. The effects of the tutoring package were analyzed using a multiple baseline design across two sets of 50 Chinese characters. The tutoring package produced improvement in the student's correct pronunciation of Chinese characters from 48% (pretutoring) to 90% (posttutoring). Results suggested that the tutoring package produced mastery pronunciation of targeted Mandarin Chinese vocalizations by a nonnative speaker.

  12. Distance learning for training business game tutors

    Directory of Open Access Journals (Sweden)

    Mariana de Toledo Marinho

    Full Text Available Abstract This work is the result of research that proposes the incorporation of Distance Learning into a Business Game as a strategy to enhance tutor training, considering entrepreneurship difficulties faced by public school teachers. Part of the problem could be attributed to subject type, because, in general, it is not common to find entrepreneurship on school curricula. The Distance Learning (DL activities were developed using the Moodle platform and structured by topic to increase educational flexibility and achieve a better balance between individual reflection and online discussion. It was developed in four steps: course content development; course evaluation by computer technicians; restructuring the course based on course evaluation done by computer technicians and course evaluation by teachers from the public school system. A preliminary test was performed with informatics technicians to technically evaluate the learning environment. Based on this, the course was restructured, applying corrections and adjustments to improve environment usability. After corrections, a final test was conducted with public school system teachers to analyze user perception, which gave a positive result. Virtual learning environment evaluation is complex and multidisciplinary, requiring the technical knowledge of internet programming and a conceptual knowledge of education, especially in the field of learning. When the evaluation done by teachers was examined, it was found that deficiencies pointed out by computer technicians had been resolved, giving a positive rating. This current research concludes that DL can improve the use of games, because it is possible to structure the content related to the learning gaps of specific groups of students. In this respect the use of games results can guide the development of content.

    White, D.J.

    1994-07-01

    Solar Turbines Incorporated has elected to pursue an intercooled and recuperated (ICR) gas turbine system to exceed the goals of the DOE Advanced Turbine Systems (ATS) program, which are to develop and commercialize an industrial gas turbine system that operates at thermal efficiencies at least 15% higher than 1991 products, and with emissions not exceeding eight ppmv NOx and 20 ppmv CO and UHC. Solar`s goal is to develop a commercially viable industrial system (3--20 MW) driven by a gas turbine engine with a thermal efficiency of 50% (ATS50), with the flexibility to meet the differing operational requirements of various markets. Dispersed power generation is currently considered to be the primary future target market for the ICR in the 5--15 MW size class. The ICR integrated system approach provides an ideal candidate for the assumed dispersed power market, with its small footprint, easy transportability, and environmental friendliness. In comparison with other systems that use water or toxic chemicals such as ammonia for NOx control, the ICR has no consumables other than fuel and air. The low pressure ratio of the gas turbine engine also is favorable in that less parasitic power is needed to pump the natural gas into the combustor than for simple-cycle machines. Solar has narrowed the ICR configuration to two basic approaches, a 1-spool, and a 2-spool version of the ATS50. The 1-spool engine will have a lower first-cost but lower part-power efficiencies. The 2-spool ATS may not only have better part-power efficiency, its efficiency will also be less sensitive to reduced turbine rotor inlet temperature levels. Thus hot-end parts life can be increased with only small sacrifices in efficiency. The flexibility of the 2-spool arrangement in meeting customer needs is its major advantage over the 1-spool. This Task 3 Topical Report is intended to present Solar`s preliminary system selection based upon the initial trade-off studies performed to date.

    The Electrodril Deep Drilling System field test demonstrations were aborted in July 1979, due to connector problems. Subsequent post test analyses concluded that the field replacable connectors were the probable cause of the problems encountered. The designs for both the male and female connectors, together with their manufacturing processes, were subsequently modified, as was the acceptance test procedures. A total of nine male and nine female connectors were manufactured and delivered during the 2nd Quarter 1980. Exhaustive testing was then conducted on each connector as a precursor to formal qualification testing conducted during the month of October 1980, at the Brown Oil Tool test facility located in Houston, Texas. With this report, requirements under Phase II, Task C-1 are satisfied. The report documents the results of the connector qualification test program which was successfully completed October 28, 1980. In general, it was concluded that connector qualification had been achieved and plans are now in progress to resume the field test demonstration program so that Electrodril System performance predictions and economic viability can be evaluated.

    To master the skills needed for microsurgery techniques, residents must enrol in a long and complex training program that includes manipulations on simulators, on ex vivo tissues and finally in vivo training. This final step consists of performing vascular anastomoses on murine models. We propose here a simulation program designed to decrease the number of rats used during the final in vivo training. Our study presents the materials used, the various exercises proposed and their evaluations. Two identical student groups were compared in the framework of the University Diploma of Microsurgery. Group A (seven students) followed a classic training program, all of whom achieved permeable vascular anastomoses. A total of 149 rats were needed for this group. Group B (seven students) first validated their manipulations on the task-trainer simulation program. A mean of 6 h was necessary to obtain this validation. All these students achieved the required permeable vascular anastomoses but only 77 rats were used for this group. This simulation program spared 72 rats, abiding by the Russell and Burch concept of a humane experimental technique, namely the 3R principles. This home-made, cost-efficient and easy-to-use task trainer included various exercises with increasing difficulty levels and a progressive scoring system. We believe that microsurgery training needs to include both simple and sophisticated tools in order to reduce the number of animals used to master these surgical skills.

    Research Methods Tutor (RMT) is a dialogue-based intelligent tutoring system for use in conjunction with undergraduate psychology research methods courses. RMT includes five topics that correspond to the curriculum of introductory research methods courses: ethics, variables, reliability, validity, and experimental design. We evaluated the effectiveness of the RMT system in the classroom using a nonequivalent control group design. Students in three classes (n = 83) used RMT, and students in two classes (n = 53) did not use RMT. Results indicated that the use of RMT yieldedstrong learning gains of 0.75 standard deviations above classroom instruction alone. Further, the dialogue-based tutoring condition of the system resulted in higher gains than did the textbook-style condition (CAI version) of the system. Future directions for RMT include the addition of new topics and tutoring elements.

    2007-11-01

    AutoTutor is an intelligent tutoring system (ITS) in which students can learn a variety of subjects through conversation in natural language with a software agent. The agent appears as a face on the screen, with a synthesized voice, and responds to typed input from the student. Student understanding is modeled from student responses, which are matched to high quality essay responses and known misconceptions and bad answers using one of several computational linguistic techniques. With ONR and NSF support a version of AutoTutor covering Newtonian dynamics at the level of Hewitt's Conceptual Physics has been developed and extensively tested. As a byproduct of this work, several thousand student responses to a small number of conceptual physics questions have been collated and mined for misconceptions. Recent work has allowed a comparison of latent semantic analysis and inverse word frequency measures of text match with expert answers. Some results from this process will be presented along with a demonstration of AutoTutor-Physics at work.

  9. Current state of ESCO activities in Asia: ESCO industry development programs and future tasks in Asian countries

    Energy Technology Data Exchange (ETDEWEB)

    Murakoshi, Chiharu; Nakagami, Hidetoshi (Jyukankyo Research Inst. (Japan))

    2009-07-01

    In Japan and other Asian countries, ESCO markets are under formation. Introduction of ESCOs to Asia took place in the 1990s. A vigorous ESCO market is already forming in Japan, South Korea, China, and Thailand. Also, in Malaysia, and the Philippines, ESCO market development is proceeding. How did these countries introduce ESCO industries? What kind of activities are being carried out, and what are future tasks? As a first step in implementing ESCO development programs, developed countries have used government support, while emerging countries have co-operated with international organisations. By classifying the types of programs and examining activities currently under way, we can understand necessary conditions for developing an ESCO industry. When we classify programs of various countries, we see that most countries implement the same kinds of measures. However, the results vary. Some countries are progressing with market development, while others have not reached the point of market formation. Analysis of factors leading to these variations is important to the future development of ESCO industries. In this paper, we describe the current state of ESCO activities in Japan and emerging countries, and we examine ESCO development programs of each country. In particular, by comparing measures taken in countries with successful ESCO market development, such as Japan, China, Thailand and India with those still trying to develop ESCO markets, such as Malaysia, and the Philippines, we analyse factors leading to success, and we illuminate future tasks for each country.

    Dancing is a complex sensorimotor activity involving physical and mental elements which have positive effects on cognitive functions and motor control. The present randomized controlled trial aims to analyze the effects of a dancing program on the performance on a motor-cognitive dual task. Data of 35 older adults, who were assigned to a dancing group or a health-related exercise group, are presented in the study. In pretest and posttest, we assessed cognitive performance and variability of minimum foot clearance, stride time, and stride length while walking. Regarding the cognitive performance and the stride-to-stride variability of minimum foot clearance, interaction effects have been found, indicating that dancing lowers gait variability to a higher extent than conventional health-related exercise. The data show that dancing improves minimum foot clearance variability and cognitive performance in a dual-task situation. Multi-task exercises (like dancing) might be a powerful tool to improve motor-cognitive dual-task performance.

  14. Impact of the Joint Task Force on Undergraduate Physics Programs for Innovation and Entrepreneurship Education in Physics

    Science.gov (United States)

    Arion, Douglas

    The Joint Task Force on Undergraduate Physics Programs has worked diligently to develop recommendations for what physics programs could and should be doing to prepare graduates for 21st century careers. While the `traditional' physics curriculum has served for many years, the demands of the new workforce, and the recognition that only a few percent of physics students actually become faculty - the vast majority entering the workforce and applying their skills to a very diverse range of problems, projects, and products - implies that a review of the education undergraduates receives is in order. The outcomes of this study point to the need to provide greater connection between the education process and the actual skills, knowledge, and abilities that the workplace demands. This presentation will summarize these considerations, and show how entrepreneurship and innovation programs and curricula are a particularly effective means of bringing these elements to physics students.

  15. Matching tutors and students: effective strategies for information transfer between circuits

    Science.gov (United States)

    Tesileanu, Tiberiu; Balasubramanian, Vijay; Olveczky, Bence

    Many neural circuits transfer learned information to downstream circuits: hippocampal-dependent memories are consolidated into long-term memories elsewhere; motor cortex is essential for skill learning but dispensable for execution; anterior forebrain pathway (AFP) in songbirds drives short-term improvements in song that are later consolidated in pre-motor area RA. We show how to match instructive signals from tutor circuits to synaptic plasticity rules in student circuits to achieve effective two-stage learning. We focus on learning sequential patterns where a timebase is transformed into motor commands by connectivity with a `student' area. If the sign of the synaptic change is given by the magnitude of tutor input, a good teaching strategy uses a strong (weak) tutor signal if student output is below (above) its target. If instead timing of tutor input relative to the timebase determines the sign of synaptic modifications, a good instructive signal accumulates the errors in student output as the motor program progresses. We demonstrate song learning in a biologically-plausible model of the songbird circuit given diverse plasticity rules interpolating between those described above. The model also reproduces qualitative firing statistics of RA neurons in juveniles and adults. Also affiliated to CUNY - Graduate Center.

  16. Analyzing Design Process and Experiments on the AnITA Generic Tutoring System

    CERN Document Server

    Brust, Matthias R

    2007-01-01

    In the field of tutoring systems, investigations have shown that there are many tutoring systems specific to a specific domain that, because of their static architecture, cannot be adapted to other domains. As consequence, often neither methods nor knowledge can be reused. In addition, the knowledge engineer must have programming skills in order to enhance and evaluate the system. One particular challenge is to tackle these problems with the development of a generic tutoring system. AnITA, as a stand-alone application, has been developed and implemented particularly for this purpose. However, in the testing phase, we discovered that this architecture did not fully match the user's intuitive understanding of the use of a learning tool. Therefore, AnITA has been redesigned to exclusively work as a client/server application and renamed to AnITA2. This paper discusses the evolvements made on the AnITA tutoring system, the goal of which is to use generic principles for system re-use in any domain. Two experiments ...

    Research continued on natural gas-fired turbines.The objective of Task 3 was to perform initial trade studies and select one engine system (Gas-Fired Advanced Turbine System [GFATS]) that the contractor could demonstrate, at full scale, in the 1998 to 2000 time frame. This report describes the results of the selection process. This task, including Allison internal management reviews of the selected system, has been completed. Allison`s approach to ATS is to offer an engine family that is based on the newest T406 high technology engine. This selection was based on a number of parameters including return on investment (ROI), internal rate of return (IRR) market size and potential sales into that market. This base engine family continues a history at Allison of converting flight engine products to industrial use.

    Osteoporosis is a serious disease characterized by muscle weakness in the lower extremities, shortened length of trunk, and increased dorsal kyphosis leading to poor balance performance. Although balance impairment increases in adults with osteoporosis, falls and fall-related injuries have been shown to occur mainly during the dual-task performance. Several studies have shown that dual-task performance was improved with specific repetitive dual-task exercises.

    The long-term objective of this task is to develop a transformational energy production technology by in- situ thermal treatment of a coal seam for the production of substitute natural gas and/or liquid transportation fuels while leaving much of the coal’s carbon in the ground. This process converts coal to a high-efficiency, low-greenhouse gas (GHG) emitting fuel. It holds the potential of providing environmentally acceptable access to previously unusable coal resources. This task focused on three areas: Experimental. The Underground Coal Thermal Treatment (UCTT) team focused on experiments at two scales, bench-top and slightly larger, to develop data to understand the feasibility of a UCTT process as well as to develop validation/uncertainty quantification (V/UQ) data for the simulation team. Simulation. The investigators completed development of High Performance Computing (HPC) simulations of UCTT. This built on our simulation developments over the course of the task and included the application of Computational Fluid Dynamics (CFD)- based tools to perform HPC simulations of a realistically sized domain representative of an actual coal field located in Utah. CO2 storage. In order to help determine the amount of CO2 that can be sequestered in a coal formation that has undergone UCTT, adsorption isotherms were performed on coals treated to 325, 450, and 600°C with slow heating rates. Raw material was sourced from the Sufco (Utah), Carlinville (Illinois), and North Antelope (Wyoming) mines. The study indicated that adsorptive capacity for the coals increased with treatment temperature and that coals treated to 325°C showed less or similar capacity to the untreated coals.

    The strategy of the ATS program is to develop a new baseline for industrial gas turbine systems for the 21st century, meeting the buying criteria of industrial gas turbine end users, and having growth potential. These criteria guided the Solar ATS Team in selecting the system definition described in this Topical Report. The key to selecting the ATS system definition was meeting or exceeding each technical goal without negatively impacting other commercial goals. Among the most crucial goals are the buying criteria of the industrial gas turbine market. Solar started by preliminarily considering several cycles with the potential to meet ATS program goals. These candidates were initially narrowed based on a qualitative assessment of several factors such as the potential for meeting program goals and for future growth; the probability of successful demonstration within the program`s schedule and expected level of funding; and the appropriateness of the cycle in light of end users` buying criteria. A first level Quality Function Deployment (QFD) analysis then translated customer needs into functional requirements, and ensured favorable interaction between concept features. Based on this analysis, Solar selected a recuperated cycle as the best approach to fulfilling both D.O.E. and Solar marketing goals. This report details the design and analysis of the selected engine concept, and explains how advanced features of system components achieve program goals. Estimates of cost, performance, emissions and RAMD (reliability, availability, maintainability, durability) are also documented in this report.

    Computer-supported learning is an increasingly important form of study since it allows for independent learning and individualized instruction. In this paper, we discuss a novel approach to developing an intelligent tutoring system for teaching textbook-style mathematical proofs. We characterize the particularities of the domain and discuss common ITS design models. Our approach is motivated by phenomena found in a corpus of tutorial dialogs that were collected in a Wizard-of-Oz experiment. We show how an intelligent tutor for textbook-style mathematical proofs can be built on top of an adapted assertion-level proof assistant by reusing representations and proof search strategies originally developed for automated and interactive theorem proving. The resulting prototype was successfully evaluated on a corpus of tutorial dialogs and yields good results.

    Healthcare professional schools across the world are implementing near-peer tutoring (NPT) programs owing to numerous benefits to both tutors and tutees. This study determined whether higher attendance at NPT sessions led to improvements in course grades for high and low performing students. Fourth-year medical students used the USMLE Step 1 question format to tutor first-year medical students during the second half of the Structure and Function (SF) module, i.e., SF2. Attendance was recorded and students were accordingly divided into three groups: high, moderate, and low-no attendance. Students' performances in SF1 and SF2 were compared using Student's t-test. Differences among the three groups were analyzed using ANOVA and Scheffé post hoc test (PStudents who earned 70-79% (C) in SF1 were further examined on the basis of their attendance rate and performance in SF2. Those who attended three or more sessions completed a survey evaluating the NPT program. Course grades were significantly higher in SF2 than SF1 for all students, regardless of attendance rate. However, students who received a C grade in SF1 and had high or moderate attendance improved significantly in their SF2 course grade. Most students agreed that the NPT program was valuable and they evaluated the tutors highly. They also agreed that NPT prepared them for course exams and Step 1, but did not reduce anxiety and stress about Step 1. The positive effect of the NPT program resulted in its expansion to include all first-year modules. Clin. Anat. 30:922-928, 2017. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Bell, A. M.; Parton, K.; Smith, E.

    2005-12-01

    Earth science classes in colleges and high schools use a variety of satellite image processing software to teach earth science and remote sensing principles. However, current tutorials for image processing software are often paper-based or lecture-based and do not take advantage of the full potential of the computer context to teach, immerse, and stimulate students. We present EarthTutor, an adaptive, interactive Intelligent Tutoring System (ITS) being built for NASA (National Aeronautics and Space Administration) that is integrated directly with an image processing application. The system aims to foster the use of satellite imagery in classrooms and encourage inquiry-based, hands-on earth science scientific study by providing students with an engaging imagery analysis learning environment. EarthTutor's software is available as a plug-in to ImageJ, a free image processing system developed by the NIH (National Institute of Health). Since it is written in Java, it can be run on almost any platform and also as an applet from the Web. Labs developed for EarthTutor combine lesson content (such as HTML web pages) with interactive activities and questions. In each lab the student learns to measure, calibrate, color, slice, plot and otherwise process and analyze earth science imagery. During the activities, EarthTutor monitors students closely as they work, which allows it to provide immediate feedback that is customized to a particular student's needs. As the student moves through the labs, EarthTutor assesses the student, and tailors the presentation of the content to a student's demonstrated skill level. EarthTutor's adaptive approach is based on emerging Artificial Intelligence (AI) research. Bayesian networks are employed to model a student's proficiency with different earth science and image processing concepts. Agent behaviors are used to track the student's progress through activities and provide guidance when a student encounters difficulty. Through individual

    We discuss the IAU Commission 46 and Office for Astronomy Development (OAD) programs that support advancing Astronomy education and research primarily in universities in developing countries. The bulk of these operational activities will be coordinated through the OAD's newly installed Task Force 1. We outline current (and future) IAU/OAD Task Force-1 programs that promote the development of University-level Astronomy at both undergraduate and graduate levels. Among current programs discussed are the past and future expanded activities of the International School for Young Astronomers (ISYA) and the Teaching Astronomy for Development (TAD) programs. The primary role of the ISYA program is the organization of a three week School for students for typically M.Sc. and Ph.D students. The ISYA is a very successful program that will now be offered more frequently through the generous support of the Kavli Foundation. The IAU/TAD program provides aid and resources for the development of teaching, education and research in Astronomy. The TAD program is dedicated to assist countries that have little or no astronomical activity, but that wish to develop or enhance Astronomy education. Over the last ten years, the ISYA and TAD programs have supported programs in Africa, Asia, Central America and the Caribbean, the Middle East, South East and West Asia, and South America. Several examples are given. Several new programs being considered by OAD Task Force-1 are also discussed. Other possible programs being considered are the introduction of modular Astronomy courses into the university curricula (or improve present courses) as well as providing access to ``remote learning`` courses and Virtual Astronomy labs in developing countries. Another possible new program would support visits of astronomers from technically advanced countries to spend their sabbatical leaves teaching and advising University Astronomy programs in developing countries.

    Student tutors in the dissection course are expected to meet high demands in their job, to fulfill these expectations they receive training. Combined tutor training is well accepted by tutors and tutees, however, it is not known how tutor training influences student learning. Deduced from the learning goals of the tutor training, a randomized, controlled, single-blinded study was set up with a quantitative cross-sectional analysis to compare student learning behavior. A total of 197 medical students, coached either by ten trained or ten untrained tutors, were enlisted in the study. To assess the students' learning behavior we employed the LIST questionnaire. A common factor analysis was calculated to extract dimensions. Factor scores of the extracted dimensions were calculated for both groups to estimate differences in learning behavior. Factor analysis of the LIST questionnaire revealed eight factors explaining 47.57% of the overall variance. The eight factors comprise: deep learning, attention, learning organization, cooperative learning, time management, learning effort, superficial learning and learning environment. Comparing the factor scores of the extracted dimensions, students coached by trained tutors learned significantly more with their fellow students (factor score in cooperative learning 0.194 vs. -0.205, ptrained by untrained tutors. Students coached by trained tutors also tend to be better organized in their learning (factor score in learning organization 0.115 vs. -0.122, p=0.16). The learning behavior of students coached by trained tutors differs from the learning behavior of students coached by untrained tutors. Students coached by trained tutors learn significantly more often in teams than their colleagues and are better organized. Copyright © 2016 Elsevier GmbH. All rights reserved.

    2006-07-01

    The role of the perceptual organization of the visual display on eye movement control was examined in two experiments using a task where a two-saccade sequence was directed toward either a single elongated object or three separate shorter objects. In the first experiment, we examined the consequences for the second saccade of a small displacement of the whole display during the first saccade. We found that between-object saccades compensated for the displacement to aim for a target position on the new object whereas within-object saccades did not show compensation but were coded as a fixed motor vector applied irrespective of wherever the preceding saccade landed. In the second experiment, we extended the paradigm to examine saccades performed in different directions. The results suggest that the within-object and between-object saccade distinction is an essential feature of saccadic planning.

    This document constitutes the generic health and safety plan for the Environmental Restoration Program (ERP). It addresses the health and safety requirements of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA); Occupational Safety and Health Administration (OSHA) 29 CFR 1910.120 standard; and EG&G Idaho, Inc. This plan is a guide to individuals who must complete a health and safety plan for a task performed for the EPR. It contains a task specific addendum that, when completed, specifically addresses task specific health and safety issues. This health and safety plan reduces the time it takes to write a task specific health and safety plan by providing discussions of requirements, guidance on where specific information is located, and specific topics in the Addendum that must be discussed at a task level. This format encourages a complete task specific health and safety plan and a standard for all health and safety plans written for ERP.

    Clinical trials suggest that higher doses of task-oriented training are superior to current clinical practice for patients with stroke with upper extremity motor deficits. To compare the efficacy of a structured, task-oriented motor training program vs usual and customary occupational therapy (UCC) during stroke rehabilitation. Phase 3, pragmatic, single-blind randomized trial among 361 participants with moderate motor impairment recruited from 7 US hospitals over 44 months, treated in the outpatient setting from June 2009 to March 2014. Structured, task-oriented upper extremity training (Accelerated Skill Acquisition Program [ASAP]; n = 119); dose-equivalent occupational therapy (DEUCC; n = 120); or monitoring-only occupational therapy (UCC; n = 122). The DEUCC group was prescribed 30 one-hour sessions over 10 weeks; the UCC group was only monitored, without specification of dose. The primary outcome was 12-month change in log-transformed Wolf Motor Function Test time score (WMFT, consisting of a mean of 15 timed arm movements and hand dexterity tasks). Secondary outcomes were change in WMFT time score (minimal clinically important difference [MCID] = 19 seconds) and proportion of patients improving ≥25 points on the Stroke Impact Scale (SIS) hand function score (MCID = 17.8 points). Among the 361 randomized patients (mean age, 60.7 years; 56% men; 42% African American; mean time since stroke onset, 46 days), 304 (84%) completed the 12-month primary outcome assessment; in intention-to-treat analysis, mean group change scores (log WMFT, baseline to 12 months) were, for the ASAP group, 2.2 to 1.4 (difference, 0.82); DEUCC group, 2.0 to 1.2 (difference, 0.84); and UCC group, 2.1 to 1.4 (difference, 0.75), with no significant between-group differences (ASAP vs DEUCC: 0.14; 95% CI, -0.05 to 0.33; P = .16; ASAP vs UCC: -0.01; 95% CI, -0.22 to 0.21; P = .94; and DEUCC vs UCC: -0.14; 95% CI, -0.32 to 0.05; P = .15).

    The Advanced Diesel Engine Component Development (ADECD) Program is a multi-year, multi-phase effort to develop and demonstrate the critical technology needed to advance the heavy-duty low heat rejection (LHR) engine concept for the long-haul, heavy-duty truck market. The ADECD Program has been partitioned into two phases. The first phase, Phase 1, was completed in 1986, resulting in definition of the Advanced Diesel Reference Engine (ADRE)III. The second phase, Phase 11/111, examines the feasibility of the ADRE concepts for application to the on-highway diesel engine. Phase 11/111 is currently underway. This project is sponsored by the U.S. Department of Energy, Office of Transportation Technologies. The work has been performed by the Detroit Diesel Corporation (DDC) under Contract DEN3-329 with the NASA Lewis Research Center, who provide project management and technical direction.

    The research and analysis program at Vitro Labs. in support of the appliance certification and enforcement program provides Vitro's recommended approach to appliance certification and enforcement (C/E). The approach established the C/E program framework, general criteria, and procedures for assuring a specified level of energy-efficiency performance for 13 categories of consumer products (furnaces, humidifiers, dehumidifiers, dishwashers, television, clothes washers, freezers, air conditioners, stoves, refrigerators, water heaters). Section 2 summarizes the recommended approach. Section 3 contains detailed evaluations and comparisons for four independent alternative approaches considered (minimal government intevention, strong certification control, strong enforcement audit, and mixed certification/enforcement). The fifth C/E approach (strong remedy/deterrent) involves the remedies available to the government should non-compliance be discovered and could affect the choice among the approaches, but this approach has not been evaluated. Section 4 summarizes the analysis methodology used to select the recommended approach. Additional information is provided in 6 appendices.

  6. Remediation of Childhood Math Anxiety and Associated Neural Circuits through Cognitive Tutoring.

    Math anxiety is a negative emotional reaction that is characterized by feelings of stress and anxiety in situations involving mathematical problem solving. High math-anxious individuals tend to avoid situations involving mathematics and are less likely to pursue science, technology, engineering, and math-related careers than those with low math anxiety. Math anxiety during childhood, in particular, has adverse long-term consequences for academic and professional success. Identifying cognitive interventions and brain mechanisms by which math anxiety can be ameliorated in children is therefore critical. Here we investigate whether an intensive 8 week one-to-one cognitive tutoring program designed to improve mathematical skills reduces childhood math anxiety, and we identify the neurobiological mechanisms by which math anxiety can be reduced in affected children. Forty-six children in grade 3, a critical early-onset period for math anxiety, participated in the cognitive tutoring program. High math-anxious children showed a significant reduction in math anxiety after tutoring. Remarkably, tutoring remediated aberrant functional responses and connectivity in emotion-related circuits anchored in the basolateral amygdala. Crucially, children with greater tutoring-induced decreases in amygdala reactivity had larger reductions in math anxiety. Our study demonstrates that sustained exposure to mathematical stimuli can reduce math anxiety and highlights the key role of the amygdala in this process. Our findings are consistent with models of exposure-based therapy for anxiety disorders and have the potential to inform the early treatment of a disability that, if left untreated in childhood, can lead to significant lifelong educational and socioeconomic consequences in affected individuals. Significance statement: Math anxiety during early childhood has adverse long-term consequences for academic and professional success. It is therefore important to identify ways to alleviate

  10. Relationships with undergraduate nursing exchange students--a tutor perspective.

    Science.gov (United States)

    Koskinen, Liisa; Tossavainen, Kerttu

    2003-03-01

    Student exchange has been used increasingly in nursing education throughout Europe as a method of learning intercultural sensitivity. In the host country, each foreign student is assigned a personal tutor to enhance learning. The aim of this study was to describe tutor-student relationships between Finnish nurse teachers and British exchange students from the tutors' perspective. The researcher's close relationship with the study context and participants caused some ethical concerns, which will be discussed. The data consisted of tutorial session observations, research diary notes, group interviews and background questionnaires. They were analysed using Spradley's developmental research sequence method for ethnographic data. The tutoring relationship was pastoral and clinical rather than academic. The pastoral aspect of the relationship was essential in assisting the students to adjust to the stress of studying in a foreign country. On the other hand, tutors were unable to support all the students to overcome their culture shock. Tutors were uncertain about their role and did not integrate Finnish culture or practice into theory, but found their role pleasant. A dialogic tutor-student relationship is important for learning intercultural sensitivity. Tutoring strategies should be developed to assist students' adjustment to the differences in the host culture and to encourage their reflection on personal, experiential and scientific cultural knowledge during their study abroad.

    1978-12-15

    The effort included the design, fabrication and Systems Verification Testing of the Deep Drilling System. The Systems Verification Test was conducted during October 1978 in a test well located on the premises of Brown Oil Tools Inc., Houston, Texas. In general, the Systems Verification test program was an unqualified success. All of the system elements of the Deep Drilling System were exercised and evaluated and in every instance the system can be declared ready for operational well demonstration. The motor/bit shaft combination operated very well and seal performance exceeds the design goals. The rig floor system performed better than expected. The power cable flexural characteristics are much better than anticipated and longitudinal stability is excellent. The prototype production connectors have functioned without failure. The cable reels and drive skid have also worked very well during the test program. The redesigned and expanded instrumentation subsystem also functioned very well. Some electronic component malfunctions were experienced during the early test stages, but they were isolated quickly and repaired. Subsequent downhole instrumentation deployments were successfully executed and downhole data was displayed both in the Electrodril instrumentation trailer and on the remote control and display unit.

  19. Impact of Science Tutoring on African Americans' Science Scores on the High School Students' Graduation Examination

    Science.gov (United States)

    Davis, Edward

    This study investigated the relationship between an after-school tutorial program for African American high school students at a Title I school and scores on the science portion of the High School Graduation Examination (HSGE). Passing the examination was required for graduation. The target high school is 99% African American and the passing rate of the target high school was 42%---lower than the state average of 76%. The purpose of the study was to identify (a) the relationship between a science tutorial program and scores on the science portion of the HSGE, (b) the predictors of tutoring need by analyzing the relationship between biology grades and scores on the science portion of the HSGE, and (c) the findings between biology grades and scores on the science portion of the HSGE by analyzing the relationship between tutorial attendance and HSGE scores. The study was based on Piaget's cognitive constructivism, which implied the potential benefits of tutorials on high-stakes testing. This study used a 1-group pretest-posttest, quantitative methodology. Results showed a significant relationship between tutoring and scores on the biology portion of the HSGE. Results found no significant relationship between the tutorial attendance and the scores on the biology portion of the HSGE or between the biology grades and scores on the biology portion of the HSGE before tutoring. It has implications for positive social change by providing educational stakeholders with empirically-based guidance in determining the potential benefit of tutorial intervention strategies on high school graduation examination scores.

  20. The First Development of Human Factors Engineering Requirements for Application to Ground Task Design for a NASA Flight Program

    Science.gov (United States)

    Dischinger, H. Charles, Jr.; Stambolian, Damon B.; Miller, Darcy H.

    2008-01-01

    The National Aeronautics and Space Administration has long applied standards-derived human engineering requirements to the development of hardware and software for use by astronauts while in flight. The most important source of these requirements has been NASA-STD-3000. While there have been several ground systems human engineering requirements documents, none has been applicable to the flight system as handled at NASA's launch facility at Kennedy Space Center. At the time of the development of previous human launch systems, there were other considerations that were deemed more important than developing worksites for ground crews; e.g., hardware development schedule and vehicle performance. However, experience with these systems has shown that failure to design for ground tasks has resulted in launch schedule delays, ground operations that are more costly than they might be, and threats to flight safety. As the Agency begins the development of new systems to return humans to the moon, the new Constellation Program is addressing this issue with a new set of human engineering requirements. Among these requirements is a subset that will apply to the design of the flight components and that is intended to assure ground crew success in vehicle assembly and maintenance tasks. These requirements address worksite design for usability and for ground crew safety.

    Based on my experience as a PBL tutor in the Faculty of Medicine since 1997, it is clear that the role of a PBL tutor is one of a master of many trades. Whilst the primary role of a PBL tutor is to ensure, as a facilitator and a guide, that students engage in self-directed learning within the tutorial setting, he or she should be able to identify issues within and outside the tutorial setting that impact on learning. A PBL tutor should know the case well before the tutorial starts, establish ground rules and recognize that the quality of learning which takes place prior to and after the tutorial by students affect personal and group dynamics within the tutorial setting. The PBL tutor occupies a central and unique role in influencing students' learning and as a mentor to students' development.

    Despite great advances, China's postgraduate education faces many problems, for example traditional lecture-based learning (LBL) method provides fewer oppotunities to apply knowledge in a working situation. Task-based learning (TBL) is an efficient strategy for increasing the connections among skills, knowledge and competences. This study aimed to evaluate the effect of a modified TBL model on problem-solving abilities among postgraduate medical students in China. We allocated 228 first-year postgraduate students at Third Military Medical University into two groups: the TBL group and LBL group. The TBL group was taught using a TBL program for immunohistochemistry. The curriculum consisted of five phases: task design, self-learning, experimental operations, discussion and summary. The LBL group was taught using traditional LBL. After the course, learning performance was assessed using theoretical and practical tests. The students' preferences and satisfaction of TBL and LBL were also evaluated using questionnaires. There were notable differences in the mean score rates in the practical test (P 80) in the TBL group was higher than that in the LBL group. We observed no substantial differences in the theoretical test between the two groups (P > 0.05). The questionnaire results indicated that the TBL students were satisfied with teaching content, teaching methods and experiment content. The TBL program was also beneficial for the postgraduates in completing their research projects. Furthermore, the TBL students reported positive effects in terms of innovative thinking, collaboration, and communication. TBL is a powerful educational strategy for postgraduate education in China. Our modified TBL imparted basic knowledge to the students and also engaged them more effectively in applying knowledge to solve real-world issues. In conclusion, our TBL established a good foundation for the students' future in both medical research and clinical work.

Currently, work is being conducted with researchers in Russia and Ukraine. Efforts aimed at evaluating and advancing technologies to support U.S. high-level waste (HLW) vitrification initiatives are being conducted in collaboration with Russian researchers. Work at Khlopin Radium Institute (KRI) is targeted at improving the throughput of current vitrification processes by increasing melting rate. These efforts are specifically targeted at challenging waste types identified at the Savannah River Site (SRS) and Hanford Site. The objectives of current efforts at SIA Radon are to gain insight into vitrification process limits for the cold crucible induction melter (CCIM) technology. Previous demonstration testing has shown that the CCIM offers the potential for dramatic increases in waste loading and waste throughput. However, little information is known regarding operational limits that could affect long-term, efficient CCIM operations. Collaborative work with the Russian Electrotechnical University (ETU) 'LETI' is aimed at advancing CCIM process monitoring, process control and design. The goal is to further mature the CCIM technology and to establish it as a viable HLW vitrification technology. The greater than two year effort conducted with the International Radioecology Laboratory in the Ukraine recently completed. The objectives of this study were: to assess the long-term impacts to the environment from radiation exposure in the Chernobyl Exclusion Zone (ChEZ); and to provide information on remediation guidelines and ecological risk assessment within radioactively contaminated territories around the Chernobyl Nuclear Power Plant

    Many faculties worldwide apply the method of problem-based learning (PBL) in their curricula as a form of instruction by which students in small groups develop problem-solving strategies on the basis of a specific case. This approach fosters self-responsible and context-dependent learning, which aims at providing an improved anchoring of knowledge. For this reason, the previous decades have seen a distribution of the method to medical schools across the world. The role of the tutor assumes particular importance since, in contrast to the traditional university system, he or she serves as a facilitator who fosters and structures content-related and group-dynamic learning processes. In some cases, this requires an intervention by the tutor. The major challenge is to intervene at the right time and in an appropriate manner. This paper presents examples of difficult PBL situations using short film sequences to demonstrate and comments on potential approaches of the tutor in attempting to resolve the problem. Standard problem situations within a PBL tutorial were defined and produced in a film. A collection of seven frequent critical PBL situations are presented in short film sequences. Potential instruments of intervention are demonstrated in the videos and discussed. The film sequences may be downloaded in the supplementary of the electronic version of this article (www.sciencedirect.com). Within the framework of a tutor-training programme, the problematic situations and interventions presented in this article will help to sensitise tutors to potentially critical PBL tutorial situations and aid the development of individual resolution approaches.

However, descriptions of on-ward PAL programs are rare. A focus group analysis of a newly established PAL program on an internal medicine ward was conducted to provide insights into PAL teaching from a student perspective.Purpose: To provide insights into students' experiences regarding their on-ward training with and without accompanying PAL tutors.Methods: A total of N=168 medical students in their sixth semester participated in the investigation (intervention group: N=88; control group: N=80. The intervention group took part in the PAL program, while the control group received standard on-ward training. There were seven focus groups with N=43 participants (intervention group: four focus groups, N=28 participants; control group: three focus groups, N=15 participants. The discussions were analyzed using content analysis.Results: The intervention group emphasized the role of the tutors as competent and well-trained teachers, most beneficial in supervising clinical skills. Tutors motivate students, help them to integrate into the ward team, and provide a non-fear-based working relationship whereby students' anxiety regarding working on ward decreases. The control group had to rely on autodidactic learning strategies when neither supervising physicians nor final-year students were available.Conclusion: On-ward PAL programs represent a particularly valuable tool for students' support in training clinical competencies on ward.

    Work in cognitive and educational psychology examines a variety of phenomena related to the learning and retrieval of information. Indeed, Alice Healy, our honoree, and her colleagues have conducted a large body of groundbreaking research on this topic. In this article we discuss how 3 learning principles (the generation effect, deliberate practice and feedback, and antidotes to disengagement) discussed in Healy, Schneider, and Bourne (2012) have influenced the design of 2 intelligent tutoring systems that attempt to incorporate principles of skill and knowledge acquisition. Specifically, this article describes iSTART-2 and the Writing Pal, which provide students with instruction and practice using comprehension and writing strategies. iSTART-2 provides students with training to use effective comprehension strategies while self-explaining complex text. The Writing Pal provides students with instruction and practice to use basic writing strategies when writing persuasive essays. Underlying these systems are the assumptions that students should be provided with initial instruction that breaks down the tasks into component skills and that deliberate practice should include active generation with meaningful feedback, all while remaining engaging. The implementation of these assumptions is complicated by the ill-defined natures of comprehension and writing and supported by the use of various natural language processing techniques. We argue that there is value in attempting to integrate empirically supported learning principles into educational activities, even when there is imperfect alignment between them. Examples from the design of iSTART-2 and Writing Pal guide this argument.

    Problem-based learning (PBL) is an established didactic approach in medical education worldwide. The impact of PBL depends on the tutors' quality and the students' motivation. To enhance students' motivation and satisfaction and to overcome the problems with the changing quality of tutors, online learning and face-to-face classes were systematically combined resulting in a blended learning scenario (blended problem-based learning--bPBL). The study aims at determining whether bPBL increases the students' motivation and supports the learning process with respect to the students' cooperation, their orientation, and more reliable tutoring. The blended PBL was developed in a cooperation of students and teachers. The well-established Seven Jump-scheme of PBL was carefully complemented by eLearning modules. On the first training day of bPBL the students start to work together with the online program, but without a tutor, on the final training day the tutor participates in the meeting for additional help and feedback. The program was evaluated by a mixed-method study. The traditional PBL course was compared with the blended PBL by means of qualitative and quantitative questionnaires, standardized group interviews, and students' test results. In addition log-files were analyzed. A total of 185 third-year students and 14 tutors took part in the study. Motivation, subjective learning gains and satisfaction achieved significantly higher ratings by the bPBL students compared with the students learning by traditional PBL. The tutors' opinion and the test results showed no differences between the groups. Working with the web-based learning environment was assessed as very good by the students. According to the log-file analysis, the web-based learning module was frequently used and improved the cooperation during the self-directed learning.

    The Hanford Site Permanent Isolation Barrier Development Program (Barrier Development Program) was organized (Adams and Wing 1986) to develop the technology needed to provide an in-place disposal capability for the US Department of Energy at the Hanford Site in southeastern Washington. The goals of the Barrier Development Program are to provide defensible evidence that final barrier design(s) will adequately control water infiltration, plant and animal intrusion, and wind and water erosion for a minimum of 1,000 years; to isolate wastes from the accessible environment; and to use markers to warn inadvertent human intruders. Evidence for barrier performance will be obtained by conducting laboratory experiments, field tests, computer modeling, and other studies that establish confidence in the barrier`s ability to meet its 1,000-year design life. The performance and stability of natural barrier analogs that have existed for several millennia and the reconstruction of climate changes during the past 10,000 to 125,000 years also will provide insight into bounding conditions of possible future changes and increase confidence in the barriers design. In the following discussion the term {open_quotes}long-term{close_quotes} references periods of time up to 1000`s of years, distinguishing it from {open_quotes}short-term{close_quotes} weather patterns covering a decade or less. Specific activities focus on planning and conducting a series of studies and tests required to confirm key aspects of the barrier design. The effort is a collaborative one between scientists and engineers from Westinghouse Hanford Company (Westinghouse Hanford) and Pacific Northwest Laboratory (PNL) to design barriers to limit movement of radionuclides and other contaminants to the accessible environment for at least 1,000 years. These activities have been divided into 14 groups of tasks that aid in the complete development of protective barrier and warning marker system.

    Problem-based learning (PBL) tutorial are conducted in small groups, and successful learning in such groups requires good group facilitating skills. There is a lack of research on actual skills employed by tutors in facilitating the group dynamics. To explore the process of PBL tutorial small groups, focusing on the tutors' actual behavior in facilitating group dynamics. Eight experienced tutors from various departments in medical colleges participated in this research. Forty tutorial group sessions were videotaped. Among the 636 tutorial intervention episodes, 142 of them were associated with facilitating group dynamics. Tutors interventions as well as their recalls were transcribed verbatim. Qualitative research methods were utilized to analyze the data. There were 10 tutorial group dynamic situations and 48 tutorial skills. Analysis of the tutors' intentions employing these skills in the 10 situations showed that tutors were trying to achieve the following aims: (1) iteration of PBL principles, (2) delegation of responsibility to the students, (3) creation of a good discussion forum, and (4) the generation of a good learning atmosphere. Results from this study provide PBL tutors with a practical frame of reference on group dynamic facilitating skills and stimulate further research on this topic.

    Full Text Available Peer tutors in higher education are frequently given vital teaching and learning work to do, but the training or professional development and support opportunities they are offered vary, and more often than not peer tutors are under-supported. In order to create and sustain teaching and learning environments that are better able to facilitate students’ engagement with knowledge and learning, the role of peer tutors needs to be recognised differently, as that of learning and teaching partners to both lecturers and students. Tutors then need to be offered opportunities for more in-depth professional academic development in order to fully realise this role. This paper explores a tutor development programme within a South African writing centre that aimed at offering tutors such ongoing and cumulative opportunities for learning and growth using a balanced approach, which included scholarly research and practice-based training. Using narrative data tutors provided in reflective written reports, the paper explores the kinds of development in tutors’ thinking and action that are possible when training and development is theoretically informed, coherent, and oriented towards improving practice.

    This study assessed the effects of preventative tutoring on the math problem solving of third-grade students with math and reading difficulties. Students (n = 35) were assigned randomly to continue in their general education math program or to receive secondary preventative tutoring 3 times per week, 30 min per session, for 12 weeks. Schema-broadening tutoring taught students to (a) focus on the mathematical structure of 3 problem types; (b) recognize problems as belonging to those 3 problem-type schemas; (c) solve the 3 word-problem types; and (d) transfer solution methods to problems that include irrelevant information, 2-digit operands, missing information in the first or second positions in the algebraic equation, or relevant information in charts, graphs, and pictures. Also, students were taught to perform the calculation and algebraic skills foundational for problem solving. Analyses of variance revealed statistically significant effects on a wide range of word problems, with large effect sizes. Findings support the efficacy of the tutoring protocol for preventing word-problem deficits among third-grade students with math and reading deficits.

Following the recently published TG-71 guidance, an organized mTG-71E databook was developed to facilitate data access and subsequent MU computation according to our clinical need. A recently released commercial secondary calculation program - Mobius3D (version 1.5.1 Electron Quick Calc (EQC (Mobius Medical System, LP, Houston, TX, USA, with inherent pencil beam algorithm and independent beam data, was used to corroborate the calculation results. For various setups, the calculation consistency and accuracy of mTG-71E and EQC were validated by their cross-comparison and the ion chamber measurements in a solid water phantom. Our results show good agreement between mTG-71E and EQC calculations, with average 2% difference. Both mTG-71E and EQC calculations match with measurements within 3%. In general, these differences increase with decreased cutout size, increased extended source to surface distance, and lower energy. It is feasible to use TG71 and Mobius3D clinically as primary and secondary electron MU calculations or vice versa. We recommend a practice that only requires patient-specific measurements in rare cases when mTG-71E and EQC calculations differ by 5% or more.

    We tested the ability of healthy participants to learn an association between arbitrary sensory cues and the weight of an object to be lifted using a precision grip between the index finger and thumb. Right-handed participants performed a series of grip-lift tasks with each hand. In a first experiment, participants lifted two objects of equal visual appearance which unexpectedly and randomly changed their weight. In two subsequent experiments, the change in object weight was indicated by cues, which were presented (i) visually or (ii) auditorily. When no cue about the weight of the object to be lifted was presented, participants programmed grip force according to the most recent lift, regardless of the hand used. In contrast, participants were able to rapidly establish an association between a particular sensory cue with a given weight and scaled grip force precisely to the actual weight thereafter, regardless of the hand used or the sensory modality of the cue. We discuss our data within the theoretical concept of internal models.

  2. The student tutor experience in a problem-based learning course: A case study

    Science.gov (United States)

    Moore, Tricia Susan

    This case study, conducted from an interpretive paradigm, illuminates contextual factors related to the tutor experience when senior undergraduate dental hygiene students served as tutors for beginning undergraduate dental hygiene students, or sophomores, in a 1-semester, 2-hour long problem-based learning (PBL) course in a Baccalaureate Dental Hygiene (BDH) curriculum during the spring semester of 2008. Data were collected using various sources and methods. Six tutors and three administrators were interviewed, tutees completed an anonymous questionnaire, the tutorial process and tutor training sessions were observed, and related documents were examined. Data analysis included open and axial coding, creation of tutor profiles, and identification of patterns. Tutor behaviors varied with respect to the nature of intervention (e.g., telling, asking, clarifying, acknowledging), emphasis (process, content, social), and facilitation style (directive, suggestive, empowering). Patterns in tutor behavior and attitudes emerged related to comfort and growth, persistence and lenience, and compliance, resistance, and innovation. Differences in tutor understanding and perception of their role and the purpose of PBL influenced the role the tutor assumed. Other factors that influenced tutor behavior included tutor intentions, tutor training, and environmental factors such as the nature of problems, allotted time, and tutorial group characteristics. The influence of these factors can be understood by applying Fishbein's integrated model of behavior prediction (Fishbein, 2008). Tutor training included experiencing the PBL student role, attending class, and sharing experiences with other tutors in weekly seminar sessions facilitated by a tutor supervisor. Tutor's gained confidence, knowledge, skills, and friendship. They also had the opportunity to see things from a new perspective, that of a teacher encouraging self-direction rather than a student depending on others for direction

    Role modelling by clinicians assists in development of medical students' professional competencies, values and attitudes. Three core characteristics of a positive role model include 1) clinical attributes, 2) teaching skills, and 3) personal qualities. This study was designed to explore medical students' perceptions of their bedside clinical tutors as role models during the first year of a medical program. The study was conducted with one cohort (n = 301) of students who had completed Year 1 of the Sydney Medical Program in 2013. A total of nine focus groups (n = 59) were conducted with medical students following completion of Year 1. Data were transcribed verbatim. Thematic analysis was used to code and categorise data into themes. Students identified both positive and negative characteristics and behaviour displayed by their clinical tutors. Characteristics and behaviour that students would like to emulate as medical practitioners in the future included: 1) Clinical attributes: a good knowledge base; articulate history taking skills; the ability to explain and demonstrate skills at the appropriate level for students; and empathy, respect and genuine compassion for patients. 2) Teaching skills: development of a rapport with students; provision of time towards the growth of students academically and professionally; provision of a positive learning environment; an understanding of the student curriculum and assessment requirements; immediate and useful feedback; and provision of patient interaction. 3) Personal qualities: respectful interprofessional staff interactions; preparedness for tutorials; demonstration of a passion for teaching; and demonstration of a passion for their career choice. Excellence in role modelling entails demonstration of excellent clinical care, teaching skills and personal characteristics. Our findings reinforce the important function of clinical bedside tutors as role models, which has implications for faculty development and

  7. An intelligent computer tutor to guide self-explanation while learning from examples

    Science.gov (United States)

    Conati, Cristina

    1999-11-01

    Many studies in cognitive science show that self-explanation---the process of clarifying and making more complete to oneself the solution of an example---improves learning, and that guiding self-explanation extends these benefits. This thesis presents an intelligent computer tutor that aims to improve learning from examples by supporting self-explanation. The tutor, known as the SE (self-explanation) Coach, is innovative in two ways. First, it represents the first attempt to develop a computer tutor that supports example studying instead of problem solving. Second, it explicitly guides a domain-general, meta-cognitive skill: self-explanation. The SE-Coach is part of the Andes tutoring system for college physics and is meant to be used in conjunction with the problem solving tasks that Andes supports. In order to maximize the system capability to trigger the same beneficial cognitive processes, every element of the SE-Coach embeds existing hypotheses about the features that make self-explanation effective for learning. Designing the SE-Coach involved finding solutions for three main challenges: (1) To design an interface that effectively monitors and supports self-explanation. (2) To devise a student model that allows the assessment of example understanding from reading and self-examination actions. (3) To effectively elicit further self-explanation that improves student's example understanding. In this work we present our solutions to these challenges: (1) An interface including principled, interactive tools to explore examples and build self-explanations under the SECoach's supervision. (2) A probabilistic student model based on a Bayesian network, which integrates a model of correct self-explanation and information on the student's knowledge and studying actions to generate a probabilistic assessment of the student's example understanding. (3) Tutorial interventions that rely on the student model to detect deficits in the student's example understanding and

    Full Text Available Adopting a direct approach to contrive sufficient focus on form (accuracy would facilitate interlanguage development without decreasing the naturalness of communication that communicative tasks can generate. This study aimed to determine the effectiveness of a proposed task-based instruction programme within a cognitive approach in fostering overall speaking proficiency of undergraduate students. 72 students from several public universities participated in the study, which employed an experimental design. The students of the experimental group received training through the proposed task-based instruction programme for three months while those in the control group received regular instruction. The preliminary English Test (PET was administered as a pre- and post-test measure of speaking proficiency. Findings of the study showed a significant improvement in the overall speaking proficiency of the students who were exposed to the proposed programme.  The findings suggest the potential of the task-based programme in enhancing undergraduate students' overall speaking proficiency.

    Full Text Available Introducción. ¿Planifican los tutores la formación de sus residentes? Si es así, ¿cómo lo hacen?, ¿existen diferencias entre lo explicitado en los programas formativos de las distintas especialidades y lo que ocurre realmente en la práctica diaria?, ¿están formados los tutores para planificar su docencia desde el punto de vista pedagógico? Sujetos y métodos. Para dar respuesta a estos interrogantes se ha llevado a cabo un estudio exploratorio de corte descriptivo. En él se ha diseñado, validado y presentado un cuestionario que recoge la opinión contrastada tanto de tutores como de sus respectivos residentes. La población la componen el total de los médicos residentes R1 (promoción 2006-2010; n = 57 y R3 (promoción 2004-2007; n = 58 de Medicina Familiar y Comunitaria de la Región de Murcia, y el total de la población de sus respectivos tutores: tutores de R1 (n = 57 y tutores de R3 (n = 58. Han participado 26 centros de salud que gestionan las tres unidades docentes de la región. Los datos se han analizado mediante el programa SPSS v. 14.0. Resultados y conclusiones. Aunque en la actividad docente de los tutores está muy presente la espontaneidad y la improvisación, existen importantes elementos de programación que hay que saber extraer e identificar porque son propios de un contexto práctico de formación. Se reconoce una mayor satisfacción de los implicados cuando el proceso formativo está más planificado.Introduction.

    Educating pre-registration nurses in clinical practice is a global issue. Within different countries problems exist in educating and supervising students in clinical practice and various models of clinical education are employed. In Wales, United Kingdom, this responsibility is divided between mentors, lecturer practitioners and link tutors. This paper reports on the third phase of a three-phase study in Wales to explore differences between mentors, lecturer practitioners and link tutors, and how they work together to assist students to integrate theory and practice. Four focus group interviews of National Health Service managers and Higher Education managers (n=22) were conducted. Qualitative content analysis revealed four themes: role characteristics and competencies, role differences, role conflict, and future options. The findings suggest a theory-practice continuum along which mentors, lecturer practitioners and link tutors occupy different positions. The article explores these different positions and offers suggestions for future role development.

    Vast distances, such as those that pervade astronomy, are difficult concepts to grasp. We are all a part of the Earth-Moon system, however most people do not comprehend the sizes and distances involved. In a pilot study, the authors found that an intervention using both discussion and kinesthetic modeling resulted in students of all ages (children up through adults) acquiring a more accurate mental representation of the Earth-Moon system. We have extended this research and are currently conducting a new study in which undergraduate students serve as "tutors" in a public observatory setting. One of our conjectures is that tutors' mental representations of the Earth-Moon system will be enhanced through their active participation in the cross-age peer tutoring activity. This work is supported in part by grants from the Center for the Integration of Research, Teaching, and Learning (CIRTL), the Vanderbilt University Learning Sciences Institute, and NSF Career grant AST-0349075.

    2015-01-01

    Medical education increasingly stresses that medical students should be prepared to take up multiple roles as a health professional. This requires the integrated acquisition of multiple competences such as clinical reasoning and decision making, communication skills and management skills. To promote such complex learning, instructional design has focused on the use of authentic, real-life learning tasks that students perform in a real or simulated task environment. The four-component instructional design model (4C/ID) model is an instructional design model that starts from the use of such tasks and provides students with a variety of learning tools facilitating the integrated acquisition of knowledge, skills and attitudes. In what follows, we guide the reader on how to implement educational programs based on the 4C/ID model and illustrate this with an example from general practice education. The developed learning environment is in line with the whole-task approach, where a learning domain is considered as a coherent, integrated whole and where teaching progresses from offering relatively simple, but meaningful, authentic whole tasks to more complex tasks. We describe the steps that were taken, from prototype over development to implementation, to build five learning modules (patient with diabetes; the young child with fever; axial skeleton; care for the elderly and physically undefined symptoms) that all focus on the integrated acquisition of the Canadian Medical Education Directives for Specialists roles in general practice. Furthermore, a change cycle for educational innovation is described that encompasses practice-based challenges and pitfalls about the collaboration between different stakeholders (students, developers and teachers) and the transition from traditional, fragmented and classroom-based learning to integrated and blended learning based on sound instructional design principles.

    2013-03-01

    Full Text Available Virtual learning environments (VLEs are used in distance learning and classroom teaching as teachers and students support tools in the teaching–learning process, where teachers can provide material, activities and assessments for students. However, this process is done in the same way for all the students, regardless of their differences in performance and behavior in the environment. The purpose of this work is to develop an agent-based intelligent learning environment model inspired by intelligent tutoring to provide adaptability to distributed VLEs, using Moodle as a case study and taking into account students’ performance on tasks and activities proposed by the teacher, as well as monitoring his/her study material access.

  14. To what extent do tutor-related behaviours influence student learning in PBL?

    Chng, Esther; Yew, Elaine H J; Schmidt, Henk G

    2015-03-01

    The purpose of this study was to investigate how tutor behaviours influence learning in problem-based learning (PBL). A previous study had indicated a significant influence of the tutor's social congruent behaviour on the PBL process and this study further investigates this finding by examining two groups of tutors displaying differences in social congruence. The participants were 77 students under the tutelage of four tutors and a self-report questionnaire ranked two tutors to be more socially congruent as compared to the other two. Student learning was measured by a concept recall test and the results from the analysis of covariance indicated a significant impact of the tutor's social congruent behaviour on learning after the problem analysis phase but not on the self-directed learning and reporting phases. It was concluded that the academic abilities of students and the small number of tutors involved may have affected the results, which led to the second part of this study. A group of 11 tutors were selected and the impact of their behaviours on student achievement measured by the module grade was examined. Results indicated that the tutor behaviours had a greater influence on average students as compared to the academically stronger and weaker students. This finding suggests that students who are academically stronger are not as reliant on the tutor while average students may depend more on the tutor to guide and motivate them in order to achieve the learning goals.

  15. Development and Evaluation of vetPAL, a Student-Led, Peer-Assisted Learning Program.

    Bates, Lucy S W; Warman, Sheena; Pither, Zoe; Baillie, Sarah

    Based on an idea from a final-year student, Bristol Veterinary School introduced vetPAL, a student-led, peer-assisted learning program. The program involved fifth-year (final-year) students acting as tutors and leading sessions for fourth-year students (tutees) in clinical skills and revision (review) topics. The initiative aimed to supplement student learning while also providing tutors with opportunities to further develop a range of skills. All tutors received training and the program was evaluated using questionnaires collected from tutees and tutors after each session. Tutees' self-rated confidence increased significantly in clinical skills and for revision topics. Advantages of being taught by students rather than staff included the informal atmosphere, the tutees' willingness to ask questions, and the relatability of the tutors. The small group size and the style of learning in the revision sessions (i.e., group work, discussions, and interactivity) were additional positive aspects identified by both tutees and tutors. Benefits for tutors included developing their communication and teaching skills. The training sessions were considered key in helping tutors feel prepared to lead sessions, although the most difficult aspects were the lack of teaching experience and time management. Following the successful pilot of vetPAL, plans are in place to make the program permanent and sustainable, while incorporating necessary changes based on the evaluation and the student leader's experiences running the program. A vetPAL handbook has been created to facilitate organization of the program for future years.

    Background Trials have demonstrated the efficacy of rigorous diet and physical activity promotion (D&PA) programs for adults at increased risk for type 2 diabetes to reduce diabetes incidence and improve measures of glycemia. Purpose To evaluate D&PA programs for individuals at increased risk for type 2 diabetes primarily to lower diabetes risk, lower body weight, and improve glycemia. Data Sources MEDLINE, Cochrane Central Register of Controlled Trials, CAB Abstracts, Global Health, and Ovid HealthStar from 1991 through 27 February 2015, with no language restriction. Study Selection 8 researchers screened articles for single group or comparative studies of combined D&PA programs with at least 2 sessions of at least 3 month duration in participants at increased risk for type 2 diabetes. Data Extraction 7 researchers extracted data—on study design, participant, intervention, outcome descriptions, and results—and assessed study quality. Data Synthesis 53 studies (30 D&PA vs. control, 13 more vs. less intensive, 13 in single programs) evaluated 66 programs. Compared with usual care, D&PA reduced type 2 diabetes incidence (RR = 0.59; 95% CI 0.51, 0.66; 16 studies), lowered body weight (net change = −2.2%; 95% CI −2.9, −1.4; 24 studies) and fasting blood glucose (net change = −0.12 mmol/L; 95% CI −0.20, −0.05; 17 studies), and improved other cardiometabolic risk factors. There was limited evidence for clinical events. More intensive programs were more effective. Limitations The wide variation in D&PA programs limited identification of features most relevant to effectiveness. Evidence on clinical outcomes and in children was sparse. Conclusions Combined D&PA promotion programs are effective to decrease diabetes incidence and improve cardiometabolic risk factors for patients at increased risk. More intensive programs are more effective. Primary Funding Source Centers for Disease Control and Prevention Community Preventive Services Task Force. PMID:26167912

    Full Text Available This paper presents an experimental study on modeling machine emotion elicitation in a socially intelligent service, the typing tutor. The aim of the study is to evaluate the extent to which the machine emotion elicitation can influence the affective state (valence and arousal of the learner during a tutoring session. The tutor provides continuous real-time emotion elicitation via graphically rendered emoticons, as an emotional feedback to learner’s performance. Good performance is rewarded by the positive emoticon, based on the notion of positive reinforcement. Facial emotion recognition software is used to analyze the affective state of the learner for later evaluation. Experimental results show the correlation between the positive emoticon and the learner’s affective state is significant for all 13 (100% test participants on the arousal dimension and for 9 (69% test participants on both affective dimensions. The results also confirm our hypothesis and show that the machine emotion elicitation is significant for 11 (85% of 13 test participants. We conclude that the machine emotion elicitation with simple graphical emoticons has a promising potential for the future development of the tutor.

    2010-05-01

    In this paper, my personal student Hannah and I narrate an account of aspects of our tutor/student relationship, features of which we consider to have wider relevance to others who occupy similar roles. The decision that we should write about our experience as personal tutor and student was one that emerged rather than was deliberately taken, and that we should write it as an autoethnography similarly became apparent. We had things to say, and wanted to present them in a style that mirrored the multifaceted relationship that developed, and which we continue to cultivate as evidenced by the writing of this piece. We suggest that the roles and relationships explored here extend beyond tutor and student boundaries, and have relevance to nurse and service-user encounters which we demonstrate through the use of particular frameworks for the analysis of our autoethnographic account. We explore these narratives of our relationship by utilizing concepts such as, 'boundaries', 'learning', 'supervision' and 'therapy'. In doing so, a shape of personal tutoring emerges which in turn may serve as a valuable teaching technique within mental health nurse education.

    2016-11-16

    Aim To explore baccalaureate nursing students' perceptions of what makes an effective tutor in problem-based learning courses, and the influence of effective teaching on students' learning and experience. Method Students enrolled in all four years of a baccalaureate nursing programme completed online surveys (n=511) and participated in focus groups (n=19). Data were analysed and combined using content analysis. Findings The data were summarised using five themes, the '5 Ps' of effective teaching in problem-based learning. Nursing students perceived effective problem-based learning tutors to be prepared with knowledge and facilitation skills, person-centred, passionate, professional and able to prepare students for success in the nursing programme. Effective tutors adjusted their approaches to students throughout the four years of the nursing programme. Conclusion Effective teaching in problem-based learning is essential and has significant effects on nursing students' learning, motivation and experience. Important attributes, skills and strategies of effective problem-based learning tutors were identified and may be used to enhance teaching and plan professional development initiatives.

    Phenomenon: Clinical skills centers allow structured training of undergraduate medical students for the acquisition of clinical skills in a simulated environment. Physician, nurse, or peer tutors are employed for training in those centers. All tutors should have appropriate training about the methodology used in the clinical skills training. Many of the studies revealed the effectiveness of various types of tutors. The aim of our study was to evaluate medical students' satisfaction with clinical skills training, and their opinions about the differences in coaching skills among the physician, nurse, and peer tutors. This study was conducted with third-year students (467 students) in 2013-2014 academic year at Hacettepe University Faculty of Medicine. Participation rate was 85 % (397 students). The students attended the suturing skill training in groups of 40 students. First, a faculty member from the Department of Medical Education delivered a video demonstration and conducted discussion. After the demonstration, the students were divided into groups of 5-6 students. A physician, nurse, or a peer tutor facilitated each group. The students were asked to complete the Coaching Skills Evaluation Form after the practicum session. It contained 13 criteria for assessing the coaching skills. Additionally, the form included a question for rating the student's satisfaction with the tutor. The performance of the tutors at each step was rated on a three-point scale. Kruskal Wallis analysis was used to compare students' scores for their tutors. The students' satisfaction with tutors was high for all of the tutors. However, there was no difference between students' scores in suturing skill, and between physician, nurse, and peer tutors' coaching skills. Insights: In this study, we revealed that physician, nurse, and peer tutors were equally effective on the students' performances. They were also regarded as effective in their teaching role by students. But the most important

    A study was conducted on the effectiveness of general physicians recently graduated from a medical school with Problem-Based Learning (PBL) curriculum as PBL tutors to expand the school's tutor pool. This study aims to investigate these non-staff tutors' effectiveness in terms of student satisfaction and learning outcomes. An experimental study was conducted of 12 PBL groups of second-year medical students (n = 40). Four PBL groups were led by non-staff tutors; the other eight groups were led by staff tutors during the two PBL units. Tutor evaluation and student satisfaction questionnaires were administered and student performance scores were analysed to compare between groups led by staff tutors and non-staff tutors. The students' overall satisfaction with the non-staff tutors on a five-point Likert-scale was high (M = 4.5 +/-.638). Additionally, the student scores on written tests were comparable between groups. Yet, in one unit, the groups led by staff tutors received significantly higher scores on the group evaluation than those led by non-staff tutors. The results of this study show that the non-staff tutors performed as effectively as the staff tutors did with regard to student achievement in written exams. Still, the findings of this study suggest that different tutor backgrounds and experiences might affect student performance beyond the written exam scores.

    Full Text Available Abstract Background Development of students' teaching skills is increasingly recognised as an important component of UK undergraduate medical curricula and, in consequence, there is renewed interest in the potential benefits of cross-year peer tutoring. Whilst several studies have described the use of cross-year peer tutoring in undergraduate medical courses, its use in the clinical setting is less well reported, particularly the effects of peer tutoring on volunteer tutors' views of teachers and teaching. This study explored the effects of participation in a cross-year peer tutoring programme in clinical examination skills ('OSCE tutor' on volunteer tutors' own skills and on their attitudes towards teachers and teaching. Methods Volunteer tutors were final year MBChB students who took part in the programme as part of a Student Selected Component (SSC. Tutees were year 3 MBChB students preparing for their end of year 'OSCE' examination. Pre and post participation questionnaires, including both Likert-type and open response questions, were used. Paired data was compared using the Wilcoxon signed-rank test. All tests were two-tailed with 5% significance level. Results Tutors reflected their cohort in terms of gender but were drawn from among the more academically successful final year students. Most had previous teaching experience. They were influenced to participate in 'OSCE tutor' by a desire to improve their own teaching and associated generic skills and by contextual factors relating to the organisation or previous experience of the OSCE tutor programme. Issues relating to longer term career aspirations were less important. After the event, tutors felt that participation had enhanced their skills in various areas, including practical teaching skills, confidence in speaking to groups and communication skills; and that as a result of taking part, they were now more likely to undertake further teacher training and to make teaching a major part

    Skills labs provide a sheltered learning environment. As close supervision and individual feedback were proven to be important in ensuring effective skills training, we implemented a cross-year peer tutor system in our skills lab of internal medicine that allowed intense training sessions with small learning groups (3-4 students) taught by one student tutor. The expectations, experiences and criticisms of peer tutors regarding the tutor system for undergraduate skills lab training were investigated in the context of a focus group. In addition, tutees' acceptance of this learning model and of their student tutors was evaluated by means of a pre/post web-based survey. 14 voluntary senior students were intensely prepared by consultants for their peer tutor activity. 127 students participated in the project, 66.9% of which responded to the web-based survey (23 topics with help of 6-point Likert scale + free comments). Acceptance was very high (5.69 +/- 0.07, mean +/- SEM), and self-confidence ratings increased significantly after the intervention for each of the trained skills (average 1.96 +/- 0.08, all p teaching model to be sufficient, and a mere 1% expressed the wish for skills training to be provided by faculty staff only. Focus group analyses with tutors revealed 18 different topics, including profit in personal knowledge and personal satisfaction through teaching activities. The ratio of 1:4 tutor/tutees was regarded to be very beneficial for effective feedback, and the personalized online evaluation by tutees to be a strong motivator and helpful for further improvements. The tutors ascribed great importance to the continuous availability of a contact doctor in case of uncertainties. This study demonstrates that peer teaching in undergraduate technical clinical skills training is feasible and widely accepted among tutees, provided that the tutors receive sufficient training and supervision.

    The Office of Industrial Programs of the Department of Energy has undertaken a program to demonstrate to industry the benefits of installing various energy-conserving devices and equipment. This report presents results on one of those systems, a high-temperature ceramic recuperator designed and manufactured by Sylvania Chemical and Metallurgical Division, GTE Products Corporation of Towanda, Pennsylvania. The ceramic cross-flow recuperator unit recovers waste heat from the hot combustion gases and delivers preheated air to high-temperature burners of various manufacture. Of the 38 host site installations included in the program, sufficient operating data were obtained from 28 sites to evaluate the benefits in terms of energy and economic savings that can be achieved. Performance and cost data are analyzed and presented for those 28 installations, which covered a variety of applications, sizes, and industry types. Except for 5 sites where unusual operating or data-collection problems were encountered, the improvements in performance of the recuperated furnaces equalled or exceeded estimates; the average of the total fuel savings for these 23 sites was 44.0 percent, some portion of which resulted from furnace improvements other than recuperation. Payback times were calculated for both total costs and for recuperator-related costs, using a cumulative annual after-tax cash flow method which includes tax investment credits, estimates of general and fuel-price inflation, and maintenance costs.

    The development of computers and artificial intelligence theory allow their application in the field of education. Intelligent tutoring systems reflect student learning styles and adapt the curriculum according to their individual needs. The building of intelligent tutoring systems requires not only the creation of suitable software, but especially the search and application of the rules enabling ICT to individually adapt the curriculum. The main idea of this paper is to attempt to specify the rules for dividing the students to systematically working students and more practically or pragmatically inclined students. The paper shows that monitoring the work of students in e-learning environment, analysis of various approaches to educational materials and correspondence assignments show different results for the defined groups of students.

    Full Text Available This paper presents a learning environment where a mining algorithm is used to learn patterns of interaction with the user and to represent these patterns in a scheme called item descriptors. The learning environment keeps theoretical information about subjects, as well as tools and exercises where the student can put into practice the knowledge gained. One of the main purposes of the project is to stimulate collaborative learning through the interaction of students with different levels of knowledge. The students' actions, as well as their interactions, are monitored by the system and used to find patterns that can guide the search for students that may play the role of a tutor. Such patterns are found with a particular learning algorithm and represented in item descriptors. The paper presents the educational environment, the representation mechanism and learning algorithm used to mine social-affective data in order to create a recommendation model of tutors.

    Science.gov (United States)

    Nguyen, Tang-Hung; Khoo, I.-Hung

    2010-06-01

    In engineering disciplines, students usually have hard time to visualize different aspects of engineering analysis and design, which inherently are too complex or abstract to fully understand without the aid of visual explanations or visualizations. As examples, when learning materials and sequences of construction process, students need to visualize how all components of a constructed facility are assembled? Such visualization can not be achieved in a textbook and a traditional lecturing environment. In this paper, the authors present the development of a computer tutoring software, in which different visualization tools including video clips, 3 dimensional models, drawings, pictures/photos together with complementary texts are used to assist students in deeply understanding and effectively mastering materials. The paper will also discuss the implementation and the effectiveness evaluation of the proposed tutoring software, which was used to teach a construction engineering management course offered at California State University, Long Beach.

    In this paper, we investigate the relationship between tutors' gaze behavior and particular kinds of linguistic behaviors. In particular, we describe how word classes are distributed over different gazing classes. For this, we collected data from human-robot interactions and used a classification...... of our participants' gazing behavior to create subsets of their utterances. The participants' speech was transcribed for 3 sessions (2 min each) of interaction with the robot and classified based on the detected gazing classes (looking at the robot, looking at the object or looking somewhere else......). The analysis shows that there are, for instance, more object related keywords when people are gazing at an object, and more personal pronouns when people are looking at the robot. Understanding the relationship between human tutors' linguistic and gazing behavior can facilitate bootstrapping the one capability...

  16. [The tutor-professor, transformer of professional practice].

    Bardallo Porras, Lola; March i Vila, Gemma

    2007-01-01

    The emerging conceptualization of the teaching-learning process brings with it a modification in the teaching role of a university professor. To think of the function of a tutor-professor from a complex perspective will help professors to develop underneath this paradigm, facilitating the construction of thinking in integrated networks having different types of knowledge which substitute fragmented and lineal knowledge characteristic to positivist thinking. From a complex paradigm, learning acquires a new sense. The complex viewpoint is rich in matrixes, complacent with diversity capable to integrate difficulties. The final objective of teaching is to accompany a student as he/she discovers and interprets reality. The most important function of a tutor is to permit a student to construct himself/herself by means of reflexive dialogue with the student's own learning experience. The tutor's role should enable a student to make use of his/her own speech, offering secure places where a student can find his/her appropriate spot, and where the pressure of an exam becomes more a stimulus to learn than a difficulty for his/her development.

    Full Text Available Abstract Background Skills labs provide a sheltered learning environment. As close supervision and individual feedback were proven to be important in ensuring effective skills training, we implemented a cross-year peer tutor system in our skills lab of internal medicine that allowed intense training sessions with small learning groups (3–4 students taught by one student tutor. Methods The expectations, experiences and criticisms of peer tutors regarding the tutor system for undergraduate skills lab training were investigated in the context of a focus group. In addition, tutees' acceptance of this learning model and of their student tutors was evaluated by means of a pre/post web-based survey. Results 14 voluntary senior students were intensely prepared by consultants for their peer tutor activity. 127 students participated in the project, 66.9% of which responded to the web-based survey (23 topics with help of 6-point Likert scale + free comments. Acceptance was very high (5.69 ± 0.07, mean ± SEM, and self-confidence ratings increased significantly after the intervention for each of the trained skills (average 1.96 ± 0.08, all p Conclusion This study demonstrates that peer teaching in undergraduate technical clinical skills training is feasible and widely accepted among tutees, provided that the tutors receive sufficient training and supervision.

  19. Evaluating Haskell expressions in a tutoring environment

    Full Text Available A number of introductory textbooks for Haskell use calculations right from the start to give the reader insight into the evaluation of expressions and the behavior of functional programs. Many programming concepts that are important in the functional programming paradigm, such as recursion, higher-order functions, pattern-matching, and lazy evaluation, can be partially explained by showing a stepwise computation. A student gets a better understanding of these concepts if she performs these evaluation steps herself. Tool support for experimenting with the evaluation of Haskell expressions is currently lacking. In this paper we present a prototype implementation of a stepwise evaluator for Haskell expressions that supports multiple evaluation strategies, specifically targeted at education. Besides performing evaluation steps the tool also diagnoses steps that are submitted by a student, and provides feedback. Instructors can add or change function definitions without knowledge of the tool's internal implementation. We discuss some preliminary results of a small survey about the tool.

  20. Interactive Tutoring in Blended Studies: Hindrances and Solutions

    2016-01-01

    Full Text Available This paper distinguishes between traditional teaching known as lecturing (the teacher centered approach; and tutoring (the contemporary technology-oriented interactive teaching/learning approach. It is based on the implementation of tutoring strategies of ‘blended studies’  at the Arab Open University. It investigates the application of modern interactive teaching/learning strategies, specifying some hindering factors in the AOU-Jordan Branch context. The factors include four variables: tutors, students, course material and assessment. The paper is based on qualitative research in terms of a real teaching/leaning context, using both observation and conversation with learners, besides the use of some quantitative data retrieved from a questionnaire in which learners’ views are sought regarding a number of relevant matters. A number of suggested solutions related to each of the hindering factors are presented, which if applied, may secure shifting the balance of the teaching/learning process to a more interactive technology-based tutoring level, which in turn will enhance learners’ opportunities for the attainment of better academic standards, and secure a higher degree of achievement of the shared educational goals of learners and the educational institution they study in.                                                                                                                                                       Keywords: blended studies, interactional teaching, lecturing, tutoring, course material, English language skills

  1. Recommendations for the shallow-crack fracture toughness testing task within the HSST (Heavy-Section Steel Technology) Program

    Recommendations for Heavy-Section Steel Technology Program's investigation into the influence of crack depth on the fracture toughness of a steel prototypic of those in a reactor pressure vessel are included in this report. The motivation for this investigation lies in the fact that probabilistic fracture mechanics evaluations show that shallow flaws play a dominant role in the likelihood of vessel failure, and shallow-flaw specimens have exhibited an elevated toughness compared with conventional deep-notch fracture toughness specimens. Accordingly, the actual margin of safety of vessels may be greater than that predicted using existing deep-notch fracture-toughness results. The primary goal of the shallow-crack project is to investigate the influence of crack depth on fracture toughness under conditions prototypic of a reactor vessel. A limited data base of fracture toughness values will be assembled using a beam specimen of prototypic reactor vessel material and with a depth of 100 mm (4 in.). This will permit comparison of fracture-toughness data from deep-cracked and shallow-crack specimens, and this will be done for several test temperatures. Fracture-toughness data will be expressed in terms of the stress-intensity factor and crack-tip-opening displacement. Results of this investigation are expected to improve the understanding of shallow-flaw behavior in pressure vessels, thereby providing more realistic information for application to the pressurized-thermal shock issues. 33 refs., 17 figs.

    The Office of Space and Defense Power Systems (OSDPS) of the Department of Energy (DOE) provides Radioisotope Power Systems (RPS) for applications where conventional power systems are not feasible. For example, radioisotope thermoelectric generators were supplied by the DOE to the National Aeronautics and Space Administration for deep space missions including the Cassini Mission launched in October of 1997 to study the planet Saturn. The Oak Ridge National Laboratory (ORNL) has been involved in developing materials and technology and producing components for the DOE for more than three decades. For the Cassini Mission, for example, ORNL was involved in the production of carbon-bonded carbon fiber (CBCF) insulator sets, iridium alloy blanks and foil, and clad vent sets (CVSs) and weld shields (WSs). This quarterly report has been divided into three sections to reflect program guidance from OSDPS for fiscal year (FY) 2000. The first section deals primarily with maintenance of the capability to produce flight quality carbon-bonded carbon fiber (CBCF) insulator sets, iridium alloy blanks and foil, clad vent sets (CVSs), and weld shields (WSs). In all three cases, production maintenance is assured by the manufacture of limited quantities of flight quality (FQ) components. The second section deals with several technology activities to improve the manufacturing processes, characterize materials, or to develop technologies for two new RPS. The last section is dedicated to studies of the potential for the production of 238Pu at ORNL.

    1993-01-01

    The primary objective of this study was the development of a time-marching three-dimensional Euler/Navier-Stokes aerodynamic analysis to predict steady and unsteady compressible transonic flows about ducted and unducted propfan propulsion systems employing multiple blade rows. The computer codes resulting from this study are referred to as ADPAC-AOACR (Advanced Ducted Propfan Analysis Codes-Angle of Attack Coupled Row). This report is intended to serve as a computer program user's manual for the ADPAC-AOACR codes developed under Task 5 of NASA Contract NAS3-25270, Unsteady Counterrotating Ducted Propfan Analysis. The ADPAC-AOACR program is based on a flexible multiple blocked grid discretization scheme permitting coupled 2-D/3-D mesh block solutions with application to a wide variety of geometries. For convenience, several standard mesh block structures are described for turbomachinery applications. Aerodynamic calculations are based on a four-stage Runge-Kutta time-marching finite volume solution technique with added numerical dissipation. Steady flow predictions are accelerated by a multigrid procedure. Numerical calculations are compared with experimental data for several test cases to demonstrate the utility of this approach for predicting the aerodynamics of modern turbomachinery configurations employing multiple blade rows.

    Physicians are often insufficiently trained in bedside teaching and mentoring skills. To develop, implement and assess a simulation-based training program designed to improve clinical teaching among physicians. We developed a one-day tutor training program based on six simulated scenarios with video-based debriefing. The program's efficacy was assessed using questionnaires completed by the participating physicians and their students. Main outcome measures were self-perceived teaching skills at baseline, after participation in the program, and following completion of the tutor role. Secondary outcome measures were the students' perceptions regarding their tutor skills. Thirty-two physicians (mean age 35.5 years, 56% females) participated in the program. Self-assessment questionnaires indicated statistically significant improvement following the program in 13 of 20 measures of teaching skills. Additional improvement was observed upon completion of the tutor role, leading to significant improvement in 19 of the .20 measures. Questionnaires completed by their students indicated higher scores in all parameters as compared to a matched control group of tutors who did not participate in the program, though not statistically significant. Most participants stated that the program enhanced their teaching skills (88%), they implement program-acquired skills when teaching students (79%), and they would recommend it to their peers (100%). Satisfaction was similar among participants with and without previous teaching experience. A novel one-day simulation-based tutor training program was developed and implemented with encouraging results regarding its potential to improve clinical teaching and mentoring skills.
