三种常用体育综合评价方法的比较研究--对2003-2004NBA现役优秀中锋竞技水平的排名

通过选用目前在体育评价中常用的三种综合评价方法:RSR法、主成分分析法和加权积分法,对2003-2004NBA现役优秀中锋竞技水平的评价、比较得出:RSR法评价属综合评价,但各指标在综合水平中的地位和作用是均等的,没有分出各指标的重要性;主成分分析法具有高度的数据化和减少变量个数特点,但原始数据需先进行标准化处理且各指标的权重由方差大小来确定,与实际要求不相符合,评价失真;加权积分法评价,通过咨询专家来确定评价指标的权重,再乘以各指标的位置百分法得分,得出综合评分,既有实践经验又有科学评分,是现行三种评价方法中的最优评价方法.

Text comprehension strategy instruction with poor readers

The goal of this study was to investigate the effects of teachingtext comprehension strategies to children with decoding andreading comprehension problems and with a poor or normallistening ability. Two experiments are reported. Four textcomprehension strategies, viz., question generation, summarizing,clarification, and predicting were taught through directinstruction and reciprocal teaching. In both experiments, effectswere measured according to a pretest – posttest – retentiontest – control group design. Dependent variables wereexperimenter-developed strategic reading and listening tests, andstandardized reading and listening comprehension tests. In thefirst experiment the subjects were 9 to 11-year-old poor readersfrom special schools for children with learning disabilities. Inthis experiment, the intervention program's texts and strategyinstructions were presented in listening settings only. Thesubjects in the second experiment were 10-year-old children fromregular elementary schools and 9 to 11-year-old children fromspecial schools. They were also poor readers but their decodingperformance was not as poor as in the subjects in experiment 1.In experiment 2, the intervention program involved textpresentations in alternating reading and listening lessons.Although in general, normal listeners performed better on allcomprehension tests than poor listeners, there were nodifferential program effects for the two listening levels. Cleareffects of both programs were found on strategic reading andlistening tests administered directly after the interventions. Inthe first experiment, maintenance test performance showedprolonged program benefits, whereas in the second experimentthese maintenance effects were blurred by unexpected gains of thecontrol groups of students, especially from regular schools.Finally, apart from some local successes, neither of the twoexperiments offered stable evidence of transfer of comprehensionstrategy training to standardized general listening and readingcomprehension tests.     

Suggestions on Effective Performance in the IELTS Oral Component

This paper is aimed at presenting some suggestions to candidates who are taking the IELTS to get higher marks in speaking section.The first suggestion is from psychological aspect,using a variety of self-help materials to improve confidence.The second is to take a close look at the marking criteria of IELTS and make good use of it.The third encourages students to form a habit of thinking critically through invoking a range of academic perspectives.Evidences show that the suggestions are effective in raising scores on the speaking component since they have ever been applied to some students of the author.
