In this Forum, we construct a history of the National Association for Research in Science Education (NARST) through the analysis of documents and through the personal perspectives of individuals. The history of NARST is inseparable
from the biography of the individuals through whose lives it was produced and reproduced. The history of NARST is a living
history that both shapes and was shaped by the biographies of its members.

ABSTRACTThis article examines trends and issues surrounding recruiting, funding, and hiring of doctoral physical education teacher education (D-PETE) students and graduates. Sources for this examination were background data collected by Boyce and her colleagues, the existing literature on these topics, and qualitative data gathered from 30 sport pedagogists during one round-table session at the National Association for Kinesiology in Higher Education (NAKHE) conference in January 2015. All three sources indicated the importance of recruiting and funding of students and hiring of graduates to the future of D-PETE programs. A number of paths were identified which sport pedagogists could follow in order to keep D-PETE programs safe and help them flourish. Unfortunately, agreement as to which of these paths the field should take was often in short supply. In the conclusions section, suggestions for future research of recruiting, funding, and hiring are made with the goal of providing data which could lead to sport pedagogists making more informed decisions regarding the future direction of D-PETE. 相似文献

Abstract In this article, I argue that a key problem for understanding the social ramifications of software is an implicit separation of software programs into two separate elements: expressive aspects, which are seen as socially driven and affectual, and functional aspects, understood as scientific and rational. In order to overcome this binary, I develop an alternative framework that examines the ways software expresses best practices, correct behaviors, and social organization. A key element of this framework is an understanding of software programs as simultaneously rhetorical and tangible objects. Given that Western society is dependent on sociotechnical systems in which software plays a crucial role, understanding the complex ways software expresses normative tasks, practices, and social orders is increasingly important. 相似文献

Abstract Although the link between exercise and body image is well documented, the considerable inter-individual variability in this relationship has been largely ignored. Therefore, the aim of the present study was to test the contributions of key body image and exercise-related moderators (age, body mass index (BMI), exercise frequency, trait body dissatisfaction, internalisation of appearance standards, and body surveillance tendencies) in predicting variability in the exercise-body satisfaction relationship. Thirty-seven undergraduate women completed a questionnaire containing the above trait-based measures and then carried a Personal Digital Assistant (PDA) for a 7-day period. Participants were instructed to use the PDA to self-report their state body satisfaction immediately following an exercise session and also when the PDA signalled at each of six random intervals throughout the day. Multilevel modelling revealed a bi-directional relationship between exercise and state body satisfaction. Moreover, post-exercise increases in state body satisfaction were strongest for individuals who were younger and engaged in regular exercise, and weakest for individuals with high BMI and/or the tendency to compare their appearance with others. These findings highlight potential limits on the efficacy of exercise-based therapy for body image disturbances. 相似文献

ABSTRACTThis study investigated changes in body composition in relation to training load determined using RPE and duration (sRPE), and its relationship with physical qualities over a preseason period. Sixteen professional academy players (age = 17.2 ± 0.7 years; stature = 179.9 ± 4.9 cm; body mass = 88.5 ± 10.1 kg) participated in the study. Body composition was assessed before and after each training phase and physical qualities assessed at the start and end of preseason. Across the whole preseason period, skinfold thickness, body fat percentage and fat mass were most likely lower (ES = ?0.73 to ?1.00), and fat free mass and lean mass were likely to most likely higher (ES = 0.31 to 0.40). Results indicated that the magnitude of change appeared phase-dependent (ES = ?0.05 to ?0.85) and demonstrated large individual variability. Changes in physical qualities ranged from unclear to most likely (ES = ?0.50 to 0.64). Small to moderate correlations were observed between changes in body composition, and TL with changes in physical qualities. This study suggests training phase and TL can influence a player’s body composition; that large inter-participant variability exists; and that body composition and TL are related to the change in physical qualities. 相似文献

Abstract The objective of this study was to provide anthropometric, physiological, and performance characteristics of an elite international handball team. Twenty-one elite handball players were tested and categorized according to their playing positions (goalkeepers, backs, pivots, and wings). Testing consisted of anthropometric and physiological measures of height, body mass, percentage body fat and endurance ([Vdot]O2max), performance measures of speed (5, 10, and 30 m), strength (bench press and squat), unilateral and bilateral horizontal jumping ability, and a 5-jump horizontal test. Significant differences were found between player positions for some anthropometric characteristics (height and percentage body fat) but not for the physiological or performance characteristics. Strong correlations were noted between single leg horizontal jumping distances with 5-, 10-, and 30-m sprint times (r = 0.51–0.80; P < 0.01). The best predictors of sprint times were single leg horizontal jumping with the dominant leg and the distance measured for the 5-jump test, which when combined accounted for 72% of the common variance associated with sprint ability. In conclusion, performance abilities between positions in elite team-handball players appear to be very similar. Single leg horizontal jumping distance could be a specific standardized test for predicting sprinting ability in elite handball players. 相似文献

This article reports on the collaboration of six states to study how simulation‐based science assessments can become transformative components of multi‐level, balanced state science assessment systems. The project studied the psychometric quality, feasibility, and utility of simulation‐based science assessments designed to serve formative purposes during a unit and to provide summative evidence of end‐of‐unit proficiencies. The frameworks of evidence‐centered assessment design and model‐based learning shaped the specifications for the assessments. The simulations provided the three most common forms of accommodations in state testing programs: audio recording of text, screen magnification, and support for extended time. The SimScientists program at WestEd developed simulation‐based, curriculum‐embedded, and unit benchmark assessments for two middle school topics, Ecosystems and Force & Motion. These were field‐tested in three states. Data included student characteristics, responses to the assessments, cognitive labs, classroom observations, and teacher surveys and interviews. UCLA CRESST conducted an evaluation of the implementation. Feasibility and utility were examined in classroom observations, teacher surveys and interviews, and by the six‐state Design Panel. Technical quality data included AAAS reviews of the items' alignment with standards and quality of the science, cognitive labs, and assessment data. Student data were analyzed using multidimensional Item Response Theory (IRT) methods. IRT analyses demonstrated the high psychometric quality (reliability and validity) of the assessments and their discrimination between content knowledge and inquiry practices. Students performed better on the interactive, simulation‐based assessments than on the static, conventional items in the posttest. Importantly, gaps between performance of the general population and English language learners and students with disabilities were considerably smaller on the simulation‐based assessments than on the posttests. The Design Panel participated in development of two models for integrating science simulations into a balanced state science assessment system. © 2012 Wiley Periodicals, Inc.
