Effects of Manipulative Instruction on Solving Area and Perimeter Problems by Students with Learning Disabilities

Abstract. A multiple baseline design was employed to test the effect of manipulative instruction on the perimeter and area problem‐solving performance of middle and high school students who had been diagnosed with LD in the area of mathematics. Modeling, prompting/guided practice, and independent practice in conjunction with manipulative training were employed to teach both perimeter and area problem‐solving skills. Analysis of data revealed that the students rapidly acquired the problem‐solving‐skills, maintained these skills over a two‐month period, and transferred these skills to a paper and pencil problem‐solving format. This research extends previous findings by revealing that use of concrete manipulatives promotes the long‐term maintenance of skills.

构建我国教练员科学训练能力评估指标体系

目前我国在对教练员训练能力的评价过程中，往往采用看教练员进过哪一级的运动队和根据教练员所带队员取得过怎样的运动成绩来进行评估．由于种种原因造成这种评价方法不能科学、准确、全面和客观地反映教练员的实际训练水平和能力．为此，本文运用文献资料法、特尔斐法、层次分析法等，构建了教练能力科学评估指标体系以及评定的标准与方法，拟对我国教练员的训练能力进行客观、合理、综合的评估。
