高考英语听力测试与雅思听力测试题型对比研究

文章对我国高考英语听力测试与英国雅思(IELTS)听力测试(学术类)的题型进行了对比研究。通过把雅思常用的五种听力测试题型应用于高考英语听力,以探讨是否有的听力测试题型比其他题型能更好地测出高考考生的英语听力理解能力。研究结果显示:所采用的五种不同的听力测试题型的测试结果呈统计上显著性差异;简答、选择和句子填空题比信息转移和配对题型的效度更高,其中简答题型的效度最高,配对题型的效度最低。

An Experimental Study of the Effect of Educational Guidance on a Selected Group of High School Sophomores

The question of an interaction over time between ability grouping and personality variables was the focus of the present study which examined pertinent data from 260 female high school students. Two standardized personality instruments, in addition to several scales designed by the E’s, were administered to students of the upper and lower ability tracks in a Catholic high school, grades 9 and 12. Ss in the lower track were found to have a lower need for achievement, a higher need to avoid failure, and a higher average score of test anxiety than Ss in the upper track. The effects of ability grouping did interact with grade level for a correlate of personality, level of aspiration. Relative to Ss in the upper track, the lower track Ss experienced a reduction in level of aspiration over time. Both future directions of associated research and educational practices were discussed within the context of the present findings.     

A Study of Sensori-Motor and Conceptual Thinking in Children between the Ages of Nine and Eighteen

In this research, the author addresses whether the application of unidimensional item response models provides valid interpretation of test results when administering items sensitive to multiple latent dimensions. Overall, the present study found that unidimensional models are quite robust to the violation of the unidimensionality assumption due to secondary dimensions from sensitive items. When secondary dimensions are highly correlated with main construct, unidimensional models generally fit and the accuracy of ability estimation is comparable to that of strictly unidimensional tests. In addition, longer tests are more robust to the violation of the essential unidimensionality assumption than shorter ones. The author also shows that unidimensional item response theory models estimate item difficulty parameter better than item discrimination parameter in tests with secondary dimensions.     

An Analysis of Some New Statistical Methods for Selecting Test Items

In this study, the relationship between student affective performance and classroom physical environment, social climate, and management style were investigated in a sample of classes in Hong Kong primary schools. The results of Pearson and canonical correlation analyses indicated that among the measures of classroom environment, perceived quality of physical environment and class master's expert power, personal power, and coercive power were the strongest predictors of affective performance. This finding supports the importance of class master's management style in the classroom environment. Students' attitudes toward school and teachers appeared to be most sensitive to variation in the classroom environment, and self-concept was the least sensitive among the seven student affective measures. Students' self-efficacy of learning and intention to drop out were moderately sensitive to classroom environment. Profiles of effective and ineffective classroom environments were also mapped. In effective classrooms, class masters care for students, pay attention to teaching, do not use force or punishment but do create a good classroom climate with their professional knowledge, personal morality, and personality. Physical environment and psychological environment are both important; a good classroom environment is highly correlated with student affective performance.     

The “None of the Above” Option in Multiple-Choice Testing: An Experimental Study

The authors assessed the effects of using “none of the above” as an option in a 40-item, general-knowledge multiple-choice test administered to undergraduate students. Examinees who selected “none of the above” were given an incentive to write the correct answer to the question posed. Using “none of the above” as the keyed option made items much more difficult (d = ?1.11). Furthermore, 45% of the time that examinees correctly selected “none of the above,” they wrote either a wrong answer (19%) or no answer (26%), and rescoring items to deny credit in these cases caused item discrimination to fall (d = ?0.35). Thus, when “none of the above” is the keyed option, credit earned by examinees with knowledge deficiencies can make items appear to have more discriminatory power than is actually the case. The authors recommend that “none of the above” should not be used as an option in multiple-choice items.     

PISA and scientific literacy: similarities and differences between the nordic countries

In this paper we have set out to search for similarities and differences between the Nordic countries concerning patterns of competencies defined as scientific literacy in the Programme for International Student Assessment (PISA) study. The first part focuses on gender differences concerning the two types of competencies, understanding of scientific concepts versus skills in scientific reasoning, based on analyses of sum scores of groups of items. The second part focuses on differences and similarities between countries based on item‐by‐item analyses. Correlations between each Nordic country (as well as the Nordic group as a whole) and every other country have been used to look for a Nordic pattern. In the last part cluster analysis has been used to see how countries establish clusters and whether these clusters represent meaningful groups in a geographical, cultural or political context.
