Improved children’s motor learning of the basketball free shooting pattern by associating subjective error estimation and extrinsic feedback

This study aimed at assessing the interaction between subjective error estimation and frequency of extrinsic feedback in the learning of the basketball free shooting pattern by children. 10- to 12-year olds were assigned to 1 of 4 groups combining subjective error estimation and relative frequency of extrinsic feedback (33% × 100%). Analysis of performance was based on quality of movement pattern. Analysis showed superior learning of the group combining error estimation and 100% feedback frequency, both groups receiving feedback on 33% of trials achieved intermediate results, and the group combining no requirement of error estimation and 100% feedback frequency had the poorest learning. Our results show the benefit of subjective error estimation in association with high frequency of extrinsic feedback in children’s motor learning of a sport motor pattern.     

Effect of Active Lessons on Physical Activity,Academic, and Health Outcomes: A Systematic Review

Purpose: The purpose of this study was to conduct a systematic review of classroom-based physical activity interventions that integrate academic content and assess the effectiveness of the interventions on physical activity, learning, facilitators of learning, and health outcomes. Method: Six electronic databases (ERIC, PubMed, Google Scholar, Science Direct, Cochrane Library, and EMBASE) and reference lists were searched for English-language articles, published January 1990 through March 2015, reporting classroom-based interventions that deliberately taught academic content using physically active teaching methods for at least 1 week duration, with physical activity, health, learning, or facilitators-of-learning outcomes. Two authors reviewed full-text articles. Data were extracted onto an Excel spreadsheet, and authors were contacted to confirm accuracy of the information presented. Results: Fifteen studies met the inclusion criteria. Six studies reporting on physical activity levels were found to have medium-to-large effect sizes. All 4 studies reporting learning outcomes showed positive effects of intervention lessons. Teachers and students were pleased with the programs, and enhanced on-task behavior was identified (n = 3). Positive effects were also reported on students’ body mass index levels (n = 3). Conclusions: Physically active academic lessons increase physical activity levels and may benefit learning and health outcomes. Both students and teachers positively received and enjoyed these teaching methods. These findings emphasize the need for such interventions to contribute toward public health policy.     

Political failure and the necessity for global democracy

Abstract

This paper aims to explore the changes in creative activities of young people – especially in the alternative media – in Indonesia before and after Reformasi. It begins with the story of the dynamics of a student press, from my personal experience – which I believe is a typical form of student/youth movement in Indonesia – and how the student’s life obviously depends on the political situation, the university policy, and the dynamics of the student’s life at that particular time. Reformasi caused political change and freedom but simultaneously, and ironically, placed the student press in a state of meaninglessness, such that it was painfully forced for search for new meanings to keep it contextually relevant in the new era. I end the paper describing the latest form of the alternative media scene of Indonesian youth, whose focus is dramatically shifting from ‘big’ political issues to issues of the celebration of communities and self‐existence.     

Modernising gender,civilising sex: perverse imaginary in the state feminist politics of Liu Yu‐hsiu

Abstract

The gender sexual politics of Liu Yu‐hsiu has been pivotal in the hegemonic ascendancy of Taiwan state feminism in recent years. Through an examination of Liu’s psychoanalytically mediated essays of cultural criticism, this article traces the contour of Liu’s sexual imaginary within the context of 1990s feminist and queer politics. Liu’s modernising project of gender equality, I argue, upholds heterosexual monogamy as a feminist ideal that seeks to purge all the masculine ills, including perversion and promiscuity. Meanwhile, queers and prostitutes come to be figured as the very negativity that must be repressed. Yet, like the Lacanian Real, they impinge on the symbolic order that Liu ordains as they thwart her desire to civilise sex.
