体育专业招生考试术科项目设置研究

本文主要采用文献资料法、专家访谈法、逻辑分析法,根据我国33年体育专业招生考试术科项目设置过程中所存在的诸多问题,提出了对术科考试项目设置进行调整的方案,以期构建科学、完善、可行、合理的术科考试项目及评价体系,形成更加公平、公正、公开的全面选拔体育优秀人才的机制,为“选好人、选准人、选对人”的高校体育专业招生初衷奠定坚实的理论基础。     

体育专业学生显性身体素质课程实验研究——以四川民族学院体教10级本科为例

用T检验、卡方检验和回归分析,对在体育专业学科教学中,采用每星期加开一次课（90分钟）的身体素质显性课程教学和没有加开身体素质显性课程教学进行一年的教学实验研究,其结果表明：（对照组）没有开设身体素质显性课程的学生100米、铅球和立定跳远成绩均不如（实验组）每星期加开一次身体素质显性课程教学的班级,实验组经过一年的实验后各项身体素质均有大幅度提高,实验组和对照组的身体素质水平呈非常显著性差异。此研究为今后体育专业课程设置和教学改革提供理论依据。     

Does student learning style affect performance on different formats of biomechanics examinations?

Students' learning style preferences have been widely adapted into teaching and learning environments. The purpose of this study was to investigate the relationship between self-reported and assessed learning style preferences (visual, auditory, reading/writing, kinesthetic: VARK) on performance in different types of multiple-choice examinations (T1: text only format and T2: visual format) given in an introductory biomechanics class. Students who enrolled in three biomechanics classes at a state university were recruited to participate in the study. Ninety students (47 males and 43 females) completed a learning style survey and two types of examinations. Results showed that approximately half of the students were assessed and self-reported as kinesthetic for their preferred learning style. There was no significant difference in test performance between students who preferred visual and reading/writing learning styles (self-reported and assessed). These students demonstrated similar learning and comprehension of biomechanical concepts regardless of whether the test material was presented in their preferred sensory mode or not. Interestingly, female students' perceptions of their learning style preference may have a positive effect on the test results when the test is presented in their preferred format.

高校学生考试心理探微

在学分制管理体系中，考试是实现“目标管理”、衡量教学质量的核心环节。但由于考试内容死板、方法陈旧，其科学性和有效性已越来越弱化。同时，它带给学生巨大的心理压力。这种压力既催生学习的动力，也滋长着某些不良现象的发生。重视学生的考试心理，改革陈旧的考试方法，建立科学有效的评估体系，是新形势下高校提高教学质量、培养高素质创新人才的重要保证。     

高考作文命题的开放研究——基于2006年高考作文命题的分析

从2006年的高考作文命题来看,高考作文命题的开放得到了进一步的推进。在一定命题范围内,考生拥有高度自主的立意权,并且越来越多地拥有自主选择写作话题的权利。更为可贵的是,这种开放并非天马行空般的漫想,在开放的同时又利用某些手段给予考生构思作答的保障,如多题选一、概念具化、寓意扩展、单字辐射、词义列举、直接提示等。     

完善教务管理系统提高管理水平

实现教务工作的计算机管理是提高教务管理水平，适应现代远程教育的需要，中央电大为此组织开发了适合各级电大使用的教务管理系统软件。经过几年的使用，发现系统存在不少问题，有些问题甚至会影响整个系统的正常运行，为此我们针对所发现的问题进行软件的二次开发，开发出适合我校使用的高效辅助软件，同时规范了系统的使用。开发的辅助软件及为规范系统的使用所采取的一些措施。     

再论化学实验能力

化学实验能力不能简单地等同于实验的操作技能 ,它是由多种成分组成的一种综合能力。实验教学中只有着眼于广义实验能力的培养 ,才能真正提高学生的化学实验能力 ,也才能真正实施素质教育 ,培养学生的创新精神和实践能力     

Four New Corrected Statistics for SEM With Small Samples and Nonnormally Distributed Data

When the assumption of multivariate normality is violated and the sample sizes are relatively small, existing test statistics such as the likelihood ratio statistic and Satorra–Bentler’s rescaled and adjusted statistics often fail to provide reliable assessment of overall model fit. This article proposes four new corrected statistics, aiming for better model evaluation with nonnormally distributed data at small sample sizes. A Monte Carlo study is conducted to compare the performances of the four corrected statistics against those of existing statistics regarding Type I error rate. Results show that the performances of the four new statistics are relatively stable compared with those of existing statistics. In particular, Type I error rates of a new statistic are close to the nominal level across all sample sizes under a condition of asymptotic robustness. Other new statistics also exhibit improved Type I error control, especially with nonnormally distributed data at small sample sizes.
