应试教育正向素质教育转轨,这就要求人们对考试在教育中的作用有一个正确的理解,使考试回归到它应有的位置上去．本文通过对一次考试成绩的分析,探讨了考试反拨作用的正确利用对指导学生学法、改进教学方法以及提高测试质量等方面的积极作用．     

Aspektorientierte Programmiertechniken im Unit-Testen

Der Artikel untersucht, wie Probleme, die speziell beim Unit-Testen objektorientierter Programme auftreten, mit Hilfe des Paradigmas aspektorientierte Programmierung gel?st werden k?nnen. Die Untersuchung stellt Schritt für Schritt die einzelnen Teilprobleme vor, f"uhrt konventionelle L?sungen auf, zeigt aspektorientierte Alternativen für die gestellten Probleme und erl"autert anhand von Code-Beispielen ihre Implementierung in der Sprache AspectJ. Die Untersuchung begleitend wird das Testframework FlexTest vorgestellt, das die praktische Umsetzbarkeit der vorgestellten Ideen demonstriert. The article examines whether problems that occur specifically during unit testing of object-oriented programs can be solved using the aspect-oriented programming paradigm. It presents the various subproblems step by step, shows conventional solutions, describes aspect-oriented solutions to the problems in a general and language-independent manner, and concludes by looking at the aspect-oriented implementation in the language AspectJ. Parallel to this, we present the test framework FlexTest, which demonstrates the practical implementability of our ideas.

Through the nominations of principals: Effective teachers of African American students share limitations of high-stakes testing

This study examines how elementary school teachers, nominated by their principals as effective teachers of African American students, perceive their effectiveness in an era of high-stakes testing that is influenced and constrained by policy dominance. The implications in this study might be useful in preparing prospective and practicing teachers to examine their instructional practices as they pursue successful outcomes with culturally diverse students.     

对B类题库建设中若干问题的思考

所谓B类题库,是指多套已组好的平行试卷的集合,其实质是"卷库",且试卷中的题目一般不标明属性和参数。在A类题库之外建设B类题库有其必要性。它不仅建设周期短、发挥攻效快、建设成本少,而且在难度控制、考试安全等方面也具有一定优势。同时,B类题库可以为最终建成A类库奠定良好的基础。B类题库可以有"试卷库"、"模块库"等多种形式,而模块则可根据需要以多种方法进行拆分。当然,B类题库也存在一些缺陷和问题,比如试卷等值、题目查(?)、试题更新等。为有效解决这些问题,我们已经研究出一些办法,并且还将继续进行探索,使B类题库在考试命题工作中发挥更大的效益和作用。     

Development of a scale on learners' views on blended learning and its implementation process

The purpose of this study was to extend the evaluation of learners' views on blended learning and its implementation process by developing and validating an objective assessment instrument. Cronbach' alpha, item analysis and item discrimination indices, principal component analysis, varimax rotation, and discriminant validity were used to measure the reliability and validity of the scale. A 50-item refined version of the scale was found to be highly reliable and of reasonable length.Further refinement was made based on principal component analysis. This indicated two major components, which facilitate the elicitation of learners' views on blended learning and its implementation process in relation to the complexity levels of the learning process.The scale is recommended to identify individual's views on blended learning and its implementation process and thus, to contribute to the improvement of a blended learning environment for learners.
