The article serves as a guide for researchers in developing evidence of validity using bivariate correlations, specifically construct validity. The authors outline the steps for calculating and interpreting bivariate correlations. Additionally, they provide an illustrative example and discuss the implications.

This book, written for both seasoned and novice researchers, presents a theory of what is called Basic and Higher Language Cognition (BLC and HLC), a theory aimed at making some fundamental issues concerning first and second language learning and bilingualism (more) empirical. The first part of the book provides background for and explication of…

The question as to which structural equation model should be selected when multitrait-multimethod (MTMM) data are analyzed is of interest to many researchers. In the past, attempts to find a well-fitting model have often been data-driven and highly arbitrary. In the present article, the authors argue that the measurement design (type of methods…

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…

With the exception of the procedures developed by Porter and colleagues (Porter, 2002), other methods of defining and measuring alignment are essentially limited to alignment between tests and standards. Porter's procedures have been generalized to investigating the alignment between content standards, tests, textbooks, and even classroom…

The overall poor quality of educational software on the market suggests that educators must continue efforts to evaluate available packages and to disseminate their findings. In this paper, weaknesses in published evaluation procedures are identified, and an alternative model, the York Educational Software Evaluation Scale (YESES), is described.…
