In this paper, we propose a potential interactional explanation of tertiary-to-secondary (dis)continuity: that of authority relations. Using secondary mathematics teachers' proof validations across two contexts, we suggest that secondary teachers' conceptions of authority shape their capacity to reconcile their positions as former mathematics…

This article provides an illustrative description of the pre-post difference index (PPDI), a simple, nontechnical yet robust tool for examining the instructional sensitivity of assessment items. Extension educators often design pretest-posttest instruments to assess the impact of their curricula on participants' knowledge and understanding of the…

The primary purpose of this study was to provide preliminary validity evidence for a 140-item form of the Vocabulary Size Test, which is designed to measure written receptive knowledge of the first 14,000 words of English. Nineteen native speakers of English and 178 native speakers of Japanese participated in the study. Analyses based on the Rasch…

The impact of biotechnologies on peoples' everyday lives continuously increases. Measuring young peoples' attitudes toward biotechnologies is therefore very important and its results are useful not only for science curriculum developers and policy makers, but also for producers and distributors of genetically modified products. Despite of…

Purpose: The purpose of this study was to determine the predictive validity of teacher report for assessing the emergent literacy skills of preschool-age children. The aims were twofold: (a) to examine predictive relationships between teacher report and direct behavioral assessment, and (b) to examine the extent to which teacher report accurately…

The purpose of this study was to develop and field test an employment screening instrument for special education teachers. The instrument developed demonstrated good reliability and concurrent validity. Both principals and special education administrators could effectively use the instrument. The instrument shows promise for helping administrators…

The zones framework conceived for the examination of thinking about teaching, is validated, and extended to the examination of thinking about learning. This is done by extending the framework to examine thinking about teaching and learning in a population of science graduate student teaching assistants. Semi-structured interviews explore these…

This study described the process of developing and validating the College Chemistry Self-Efficacy Scale (CCSS) that can be used to assess college students' beliefs in their ability to perform essential tasks in chemistry. In the first phase, data collected from 363 college students provided evidence for the validity and reliability of the new…

This study investigated the effects of a training package (written manual, individual training session, and ongoing verbal feedback) on middle school peer tutors' use of embedded, constant time delay procedures and on the learning outcomes for students with significant cognitive disabilities in general education settings. The study data showed…

This guide is intended to help elementary school educators as well as school and district administrators develop and implement effective prevention and intervention strategies that promote positive student behavior. The guide includes five recommendations and indicates the quality of the evidence that supports them: (1) Identify the specifics of…

This article focuses first on fundamental trends weakening the European--specifically, the Slovenian--economy and social structure, which are creating a two-class system consisting of an undereducated/uneducated population unable to compete for employment in an economy increasingly requiring more education to update employees' skills. Learning and…

The current study compared the effects of video-based reflection versus a memory-based reflection (i.e., no video) on scores for written reflections of preservice teachers who were completing a special education method course. The results of a counterbalanced design show that the use of a videotape was associated with slightly higher mean scores…

In evaluating the success of teacher development programs, valid and scalable measures of teaching practice are needed. We have developed and validated the Science Lesson Plan Analysis Instrument (SLPAI) for quantitative evaluation of teacher-generated multiday lesson plans. This paper presents the SLPAI as a complement to surveys and classroom…

This paper assesses the construct validity of the dimensions of teaching presence, one of three types of presence articulated in Garrison, Anderson, and Archer's [Garrison, D.R., Anderson, T., and Archer, W. (2000). "Critical inquiry in a text-based environment: Computer conferencing in higher education." "The Internet and higher education", 2,…

In foreign language testing, as in all testing, validity is the primary criterion for test quality. However plausible the concept of validity, in practice it is not always easy to arrive at congruence between the test situation and the real-life situation the learner is expected to master. Some language educators make authenticity a major…
