The role of reduced frequency of knowledge of results during constant practice

Two experiments were conducted to further examine the effects of reduced knowledge of results (KR) frequency on the learning of motor skills during constant practice. In Experiment 1, participants in five KR conditions (100% KR, 50% KR-fade, 50% KR-reverse fade, 50% KR-alternative, and 50% KR-random) practiced a movement timing task. In Experiment 2, participants in two KR conditions (100% KR and 50% KR-fade) practiced a waveform reproduction task. The results of both experiments failed to indicate that reduced KR frequency was more effective in promoting learning than the 100% KR conditions. The present study adds to the increasing number of experiments that do not find a benefit of reduced KR frequency on learning in constant practice.

谈写"引言"

绝大多数论文和许多一般性文章的开头都有引言,这好像已经成了一种惯例. 有必要写好引言,因为它是论文或一般性文章的一个组成部分,而且比较重要.说它重要,是因为一般在此处交代本题的目的、性质和范围,述评文献,阐述理论基础,提出问题与假设,说明研究方法、研究结果与论纲,以至为术语定义,交代待研究问题等.这些,实际上是正文的背景材料,用以表明正文所处的环境,读了这一部分才能更好地理解正文.     

我国女子撑竿跳高技术的运动学分析

采用高速摄影与影片解析的方法,对参加１９９６年全国田径锦标赛的６名优秀女子撑竿跳高运动员的技术进行测试,用握杆高度、人体质心速度变化和转动惯量等指标来揭示人—杆系统的运动学规律及其特征。结果表明,孙彩云的“低髋摆体”技术较先进。     

游泳运动员负荷后不同姿势放松游对血乳酸清除的影响

我们通过实验发现 :负荷后采用非主项姿势放松游血乳酸清除速率明显高于主项姿势放松游 (P <0 .0 5 -0 .0 1 ) ,说明负荷与放松之间姿势的转换 ,改变了原负荷肌群的负荷强度 ,并动员了非负荷肌参与活动 ,从而提高了放松活动效果。

Which do students prefer to evaluate their essays: Peers or computer program

The purpose of this study was to investigate problems and potentials of new technologies in English writing education. The effectiveness of automated writing evaluation (AWE) (MY Access) and of peer evaluation (PE) was compared. Twenty‐two English as a foreign language (EFL) learners in Taiwan participated in this study. They submitted their draft to MY Access, received feedback from this automated grading system and then made some revision. In addition to the AWE, they also had peer revision in writing class. Three issues, including how writers used the feedback from these two kinds of evaluation, what progress they made in writing and how they perceived these two kinds of evaluation, are discussed. Results showed that EFL learners in Taiwan generally opted for PE over AWE. These findings raise several relevant issues, including social learning, feedback strategies, computer anxiety and cultural impact.

What emotional-centred challenges do children attending special schools face over primary–secondary school transition?

Primary–secondary school transition encompasses multiple social, academic and environmental changes which can negatively impact children’s emotional well-being. Children with Social, Emotional and Mental Health difficulties (SEMH) are believed to be especially vulnerable during this time. However, the voices of children with SEMH are heavily underrepresented in this field within practice and research. The present case study examined how children with SEMH difficulties within one special school experience primary–secondary school transition and how they are supported, in order to make recommendations to improve this period. The case study was qualitative and longitudinal, conducted over 18-months and methodologies included ethnographic observations, child photo-elicitation focus groups (with 11 Year 6 children) and three adult interviews. Findings demonstrated that over primary–secondary school transition children with SEMH difficulties (a) negotiate significant structural changes in support (often unanticipated) and (b) need to feel a sense of safety and belonging. To manage this effectively, transition provision for children with SEMH difficulties needs to consider their short-term emotional well-being whilst still in primary school, in addition to their long-term well-being looking ahead to secondary school. Greater collaboration and communication across schools and stakeholders can help ensure children receive continuity in standards and support.
