Mobile serious educational games (SEGs) show promise for promoting scientific practices and high engagement. Researchers have quantified this engagement according to flow theory. This study investigated whether a mobile SEG promotes flow experience and scientific practices with eighth-grade urban students. Students playing the game (n = 59) were compared with students in a business-as-usual control activity (n = 120). In both scenarios, students worked in small teams. Data measures included an open-ended instrument designed to measure scientific practices, a self-report flow survey, and classroom observations. The game players had significantly higher levels of flow and scientific practices compared to the control group. Observations revealed that game teams received less whole-class instruction and review compared to the control teams. Game teachers had primarily a guide-on-the-side role when facilitating the game, while control teachers predominantly used didactic instruction when facilitating the control activity. Implications for these findings are discussed.  相似文献

Research into professional decision-making indicates that judgements tend not to be made on a rational, systematic basis, but are often formed rapidly and intuitively from a limited set of cues. This study addresses the issue of whether and how teachers assess the literacy competencies of young children prior to starting formal schooling in a UK context. Seven Reception teachers from four primary schools were asked to make literacy predictions for the incoming cohort of children aged 4 to 5 years. Data are presented based on interviews with the teachers, completion of baseline literacy assessments, and the scrutiny of daily reading records. The study explores the factors which influence teacher predictions for 30 children, including 17 for whom literacy success was predicted and 13 for whom literacy difficulties were anticipated. The study shows that teachers do indeed form early judgements about children based on pragmatic factors, with a strong link between teacher predictions and families' socioeconomic status. Importantly, initial representations of children as 'likely to fail' tend to become more permanent over time, whilst teachers are also inclined to provide less support for children expected to perform poorly. Implications for professionals are discussed in relation to the Code of Practice for identifying children with special educational needs and new guidelines for baseline assessment of children at school entry recently issued to UK headteachers.  相似文献

The O.E.C.D. reportTowards new structures of post-secondary education (1971) outlines the main problems associated with the approach to mass higher education. Two aspects are described; firstly alternative structures for the system as a whole and secondly short cycle higher education.
Résumé Le rapport de l'O.C.D.E.Vers de nouvelles structures de l'enseignement post-secondaire (O.C.D.E., 1971) passe en revue les principaux problèmes posés par l'enseignement supérieur de masse. Deux directions sont offertes à la reflexion, d'abord l'examen de ce que pourraient être d'autres structures pour le système d'enseignement dans son ensemble, ensuite la question d'un cycle court de l'enseignement supérieur.

ABSTRACT

Purpose

To compare the occurrence and characteristics of repeated-sprint (RS) activity in elite team sport competition when classified according to speed and/or acceleration, and their interaction via metabolic power (Pmet). Methods: Elite male hockey players (N = 16) wore player-tracking devices in six international matches. Sprint efforts were defined using four separate classifications: speed >5.5 m?s?1, acceleration >1.5 m?s?2, speed-or-acceleration, and Pmet >25.5 W?kg?1. RS bouts were defined as ≥3 efforts with mean recovery ≤21 s. For Pmet, RS bouts were also classified using a maximal recovery period ≤21 s. The number of sprint efforts and RS bouts, and the number of efforts, effort durations and recovery periods within RS bouts, were compared across each classification method, and between mean and maximal recovery criteria. Results: More RS bouts were identified via Pmet (8.5 ± 2.8) than either speed and/or acceleration, and comprised more efforts (4.0 ± 0.4) with shorter recovery periods (11.5 ± 1.8 s). Fewer RS bouts (7.3 ± 2.8 vs. 8.5 ± 2.8) were identified with a maximum rather than mean recovery criterion. Conclusions: Definitions of sprint efforts and recovery periods which reflect ATP depletion and replenishment via Pmet suggest that RS activity occurs frequently in team sport competition, and is more demanding than when speed and/or acceleration are used to define RS activity in variable-speed locomotion.  相似文献
