The relationship between functional potential and field performance in elite female wheelchair basketball players

The functional classification system for wheelchair basketball is based on an analysis of the players' functional resources through field-testing and game observation. Under this system, players are assigned a score of 1 to 4.5. The aim of this study was to determine if the wheelchair basketball player classification system reflects the existing differences in performance of elite female players. During the World Championship for Wheelchair Basketball in Sydney 1998, eight teams were videotaped for three 40-min games for a total of 120?min per team. Fifty-nine female players (Class I [1 and 1.5 points] n?=?12; Class II [2 and 2.5 points] n?=?20; Class III [3 and 3.5 points] n?=?13; Class IV [4 and 4.5 points] n?=?14) were retained for a detailed performance analysis by means of the Comprehensive Basketball Grading System (CBGS). Two-way analysis of variance showed high point players to perform better compared with low point players for the majority of variables determining the quality of game performance. A lack of significant differences between two adjacent classes was explained on the basis of the methodological approach, the class–position relationship in this sample, and the performance level of women's wheelchair basketball. We conclude that the performance of elite female wheelchair basketball players is dependent on functional ability.     

Participation in organized sports,physical education,therapeutic exercises,and non-organized leisure-time physical activity: how does participation differ between childhood cancer outpatients and healthy peers?

Most childhood cancer survivors are insufficiently active. Researchers are focusing on strategies to increase physical activity (PA). However, a detailed understanding of participation in specific types of PA is missing, meaning current strategies may lack relevant information. Thus, our study sought to analyze participation in different types of PA commonly engaged in by children: organized sports, physical education in school (PES), therapeutic exercise, and non-organized leisure-time PA. Thirty-eight childhood cancer outpatients and 51 healthy children completed questionnaires. Compared to healthy children, childhood cancer outpatients, especially those who are shortly after cessation of inpatient treatment, participated significantly less often in organized sports and PES and significantly more often in therapeutic exercise compared to the healthy children. Considering organized sports and PES afford children unique social benefits and provide the potential to motivate lifelong activity, future efforts should be placed on ensuring children with cancer can access these types of PA. Educating parents, teachers, and coaches, exploring referral pathways to exercise professionals and providing individual support may enhance participation rates in organized PA and should be investigated.     

The development of the Teachers’ Attitudes toward Career Learning Index (TACLI)

Teachers play an important role supporting young people to form their career identities and to make successful transitions into further learning and work. In England, there has been limited research that has looked specifically at the role of teachers and none of which has tried to establish a measure of teacher attitude toward careers work. This article details the development of the Teachers’ Attitudes toward Career Learning Index, which was created to measure attitudes and engagement in career learning on teachers in England. The instrument went through a survey design process which included content validity and construct validity components. The process identified five underlying factors in teachers’ attitude and engagement in careers work: (1) career learning and support practices, (2) school career strategy attitudes, (3) subject career learning attitudes, (4) career support attitudes, and (5) school career strategy practices. This process helped refined initial theoretical constructs regarding teachers’ roles in careers learning.     

Pedagogical differences during a science and language intervention for English language learners

The purpose of this study was to compare and describe 8 fifth-grade classrooms by their teachers pedagogy during a quasiexperimental, longitudinal, and field-based project focused on increasing English language learners' (ELLs') achievement in science and language. The larger study found statistically significant and positive intervention effects in favor of the treatment group on measures of science and language achievement. This study adds an in-depth analysis of the teacher pedagogical practices contributing to students' science and language achievement as captured by an observational instrument used during the project. Results from the analysis show how treatment teachers, when compared to control teachers, focused on activities promoting verbal and written interaction among the students and dense cognitive language use during science inquiry instruction. The findings support the importance of effectively using language in the science classroom to improve ELLs' science and language achievement. Implications for future research and practice are discussed.     

Knowledge producers or knowledge consumers? Argumentation and decision making about environmental management

A longitudinal study of 250 students following the Salters Advanced Chemistry (SAC) course probed a range of chemical ideas including the exothermicity of bond formation and the development of thinking about covalent, ionic and intermolecular bonds. Students responded to the same diagnostic questions on three occasions: at the start, after eight months and sixteen months of a twenty-month course. At the start, many students demonstrated misunderstandings about these chemical ideas, but in general their understanding improved as the course progressed. By the end of the study, about half knew that bond making is exothermic. Initially, few described covalent bonds accurately or understood hydrogen bonding. A majority gave responses at the final survey which were in line with ideas and language a chemist may use. Students attributed changes to the use of context-based materials including a drip-feed approach which allowed their understanding to develop over time. However, some aspects of chemical bonding, including ionic bonding and intermolecular bonds other than hydrogen bonds remained problematic for students despite explicit teaching. The findings have implications for post-16 chemistry teaching, suggesting that a review of teaching strategies is needed in some areas.     

An ERP study of emotional face processing in the adult and infant brain

To examine the ontogeny of emotional face processing, event-related potentials (ERPs) were recorded from adults and 7-month-old infants while viewing pictures of fearful, happy, and neutral faces. Face-sensitive ERPs at occipital-temporal scalp regions differentiated between fearful and neutral/happy faces in both adults (N170 was larger for fear) and infants (P400 was larger for fear). Behavioral measures showed no overt attentional bias toward fearful faces in adults, but in infants, the duration of the first fixation was longer for fearful than happy faces. Together, these results suggest that the neural systems underlying the differential processing of fearful and happy/neutral faces are functional early in life, and that affective factors may play an important role in modulating infants' face processing.     

A Conflict in Your Head: An exploration of trainee science teachers’ subject matter knowledge development and its impact on teacher self‐confidence

Teachers’ subject matter knowledge (SMK) is one factor contributing to teaching ‘successfully’, as this provides a basis from which pedagogical content knowledge develops. UK‐based trainee science teachers teach all sciences to age 14 and often up to age 16. Trainees have specialist science knowledge in chemistry, physics, or biology from their degrees. Other sciences may not have been studied since school. Thus, trainee science teachers often teach ‘outside specialism’. The extent to which teaching within and outside specialism influences successful teaching, ensuring learning objectives are achieved, was investigated. The sources seventy‐one trainees use for preparing within and outside specialism science lessons for 11–14‐year‐olds and 14–16‐year‐olds and effects on teacher self‐confidence of working in these two domains were probed by questionnaire and interview. All trainees responded to open and closed questions, and Likert‐scale statements exploring preferences for teaching, self‐confidence, handling subject‐related questions within and outside specialism, and attitudes towards learning new SMK. A subgroup of 12 trainees participated in individual semi‐structured interviews. The results are counter‐intuitive: trainees teach more successful lessons outside their specialism, particularly in the early stages. This relates to using a richer range of SMK sources, including, crucially, advice from experienced colleagues. Within specialism, trainees report an inability to select appropriate knowledge and/or strategies and a sense of conflict in teaching inaccurate information. Some ‘anxious’ trainees rely heavily on extant materials for outside specialism teaching. ‘Super‐confident’ trainees able to teach any science focus on selection of appropriate instructional strategies and realise early on the need to transform SMK.
