普通逻辑基本规律教学摭谈     

裴仁伟 《钦州学院学报》2001,16(1):54-57

在同一律教学中 ,要注意讲清什么是“同一思维过程”、什么是“A是A”以及“合理违反同一律”的特殊情况。在不矛盾律教学中 ,要注意讲清“看似矛盾 ,实质上并不矛盾”的概念或判断 ,注意分析具有隐蔽性的逻辑矛盾。在排中律教学中 ,对人们的某些思维或表述 ,要结合语言环境加以分析 ,不能生搬硬套  相似文献

在高校体育教学中应发挥学生的主体性作用 :学生自主选择课程内容、自主选择任课教师、自主选择上课时间 ;上课突出提高学生参与的积极性 ,最大限度地发挥学生的创造性。加强对学生学习方法和练习方法的指导 ,提高学生自学、自练的能力 ;考核要通过学生自评、互评和教师评定 ,实现三转变 :从终结评价向终结与过程评价结合转变 ;从内容单一评价向多元评价转变 ;从教师评价向师生评价转变 ;同时要发挥教师的主导作用  相似文献   

East Meets West in Assessment Development: Western Technical Assistance to Eastern Needs. Part III. Reform of an Examination System: Shoulder to Shoulder in the Polish SMART Project     

Annemarie de Knecht-van Eekelen  Steven Bakker  Gerben van  Lent 《Educational Measurement》2001,20(3):33-35

This is Part III of a three part series describing the consultancy and training demands that are encountered in technical assistance projects in Central and Eastern Europe. Part I dealt with strategic issues for a successful delivery of "Western Technical Assistance to Eastern Needs." Part II highlighted project management and co-operation aspects in delivering support to the Romanian Assessment and Examination Service. In this part, we address training of Polish subject experts who were preparing to take on responsibility for a decentralized and strongly innovative final exam, the Matura.  相似文献

Coordination variability and skill development in expert triple jumpers   总被引：1，自引：0，他引：1  

Wilson C  Simpson SE  van Emmerik RE  Hamill J 《Sports biomechanics / International Society of Biomechanics in Sports》2008,7(1):2-9

The aim of this study was to examine the influence of skill of expert triple jumpers on the coordination variability of lower extremity intra-limb couplings. In contrast to the traditional motor learning perspective, we hypothesized that as skill and thus performance increases, movement coordination variability will also increase. Three-dimensional kinematic and ground reaction force data were collected during the hop-step transition phase of the triple jump. Relative motion plots and a modified vector coding technique were used to quantify the coordination variability across the trials. The results were consistent with a U-shaped curve, representing coordination variability, as skill increases. The high coordination variability in less skilled athletes is present while the appropriate characteristics defining the movement coordination patterns are acquired. This coordination variability may not be beneficial to performance. As the refinement of these characteristics is achieved, coordination variability decreases, resulting in a more consistent or regulated performance. In the final stages of developing a skilled performance, a functional variability is accessed that brings flexibility to the system allowing it to cope with perturbations. This study highlights the need to address the learning effect when analysing coordination variability from a dynamical systems perspective.  相似文献   

Reading Progress Monitoring for Secondary‐School Students: Reliability,Validity, and Sensitivity to Growth of Reading‐Aloud and Maze‐Selection Measures     

Renáta Tichá  Christine A. Espin  Miya Miura Wayman 《Learning disabilities research & practice》2009,24(3):132-142

The validity and reliability of curriculum‐based measures in reading as indicators of performance and progress for secondary‐school students were examined. Thirty‐five grade 8 students completed reading aloud and maze‐selection measures weekly for 10 weeks. Criterion measures were the state standards test in reading and the Woodcock–Johnson III Test of Achievement. Different time frames for each measure were compared. Most alternate‐form reliability coefficients were above .80. Criterion‐related validity coefficients ranged from .77 to .89. No differences related to time were found. Only maze selection reflected significant growth, with an average increase of 1.29 correct choices per week. Maze growth was related to the reading performance level and to change on the Woodcock–Johnson III from pre‐ to posttest.  相似文献
