提高英语主观型试题的测试可靠性

虽然客观型试题在测试学生的语言能力上有很强的优势,但在实践中它的负面影响也越来越明显。主观型试题能更有效地测量学生的语言表达能力和交际能力。主观型试题编题相对比较容易,但评分却很难。要合理分析造成主观型试题信度低的原因,提出解决的方法。     

试论考研信息资源的开发和利用

随着我国高校考研人数的逐渐增加,考研信息的需求也不断扩大.高校图书馆加强考研信息资源的开发和利用成为一种迫切需要,图书馆应该不断开发现有馆藏资源、电子资源和人力资源,不断丰富考研文献信息资源,开展多方位、多途径的个性化的专题考研信息服务工作,从而逐步提高图书馆的整体服务水平.

Quality Control for Scoring Tests Administered in Continuous Mode: An NCME Instructional Module

Quality control (QC) in testing is paramount. QC procedures for tests can be divided into two types. The first type, one that has been well researched, is QC for tests administered to large population groups on few administration dates using a small set of test forms (e.g., large‐scale assessment). The second type is QC for tests, usually computerized, that are administered to small population groups on many administration dates using a wide array of test forms (CMT—continuous mode tests). Since the world of testing is headed in this direction, developing QC for CMT is crucial. In the current ITEMS module we discuss errors that might occur at the different stages of the CMT process, as well as the recommended QC procedure to reduce the incidence of each error. Illustration from a recent study is provided, and a computerized system that applies these procedures is presented. Instructions on how to develop one's own QC procedure are also included.     

On the Pitfalls of Estimating and Using Standardized Reliability Coefficients

The population discrepancy between unstandardized and standardized reliability of homogeneous multicomponent measuring instruments is examined. Within a latent variable modeling framework, it is shown that the standardized reliability coefficient for unidimensional scales can be markedly higher than the corresponding unstandardized reliability coefficient, or alternatively substantially lower than the latter. Based on these findings, it is recommended that scholars avoid estimating, reporting, interpreting, or using standardized scale reliability coefficients in empirical research, unless they have strong reasons to consider standardizing the original components of utilized scales.

A journey from the classroom to the world of educational reform: a study of three Korean teachers’ practitioner inquiry

This article explores three Korean teachers’ experiences of carrying out practitioner inquiry as a means of providing meaningful teaching under the test-centred schooling regime in Korea. Practitioner inquiry is a concept that includes multiple genres of educational research such as action research, teacher research, and self-study that aim to change practitioners’ individual practice and, ultimately, the schooling in a society. Based on the analysis of qualitative data, the researcher found that teachers developed their knowledge and expertise in their specific areas of interest and developed strong motivations for transforming the education system. However, their inquiry was limited in practice due to the imposition of test preparation and a prescribed national curriculum. As a result, greater collaboration among practitioners, which not just involves teachers, but wider entities such as administrators, policy makers, and researchers, is required to challenge the current unjust system.     

Answer changing in testing situations: the role of metacognition in deciding which answers to review

The purpose of our study was to examine the issue of answer changing in relation to students’ abilities to monitor their behaviour accurately while responding to multiple-choice tests. The data for this study were obtained from the final examination administered to students in an educational psychology course. The results of the study indicate that decision making regarding answer changing can be informed by metacognitive monitoring when a student's attention is drawn to cues solicited during testing. However, answer changing can be a “tricky” test-taking strategy, and how it relates to test performance is based on an interplay of variables both at a person level as well as at a task level. This is probably why this strategy is frequently misunderstood by both test-takers and educators.
