In an attempt to add to the current body of research on written corrective feedback (CF), the current study reports on a nine-week intervention, which initially focused on the effect of direct written CF on learners' use of English articles in their writing and then examined the effect of adding metalinguistic explanation to this CF type; and…

This brief considers the problem of using value-added scores to compare teachers who work in different schools. The author focuses on whether such comparisons can be regarded as fair, or, in statistical language, "unbiased." An unbiased measure does not systematically favor teachers because of the backgrounds of the students they are…

Redistributing highly effective teachers from low- to high-need schools is an education policy tool that is at the center of several major current policy initiatives. The underlying assumption is that teacher productivity is portable across different schools settings. Using elementary and secondary school data from North Carolina and Florida, this…

This paper examines whether teachers in schools serving students from high-poverty backgrounds are as effective as teachers in schools with more advantaged students. The question is important. Teachers are recognized as the most important school factor affecting student achievement, and the achievement gap between disadvantaged students and their…

This article examines students from ethnic minorities and majorities with regard to the relationships between their social and academic integration and their quality of learning. A total of 523 students at four universities completed a questionnaire: analyses of variance were used to examine mean differences, and structural equation modelling…

The differences between edumetric and psychometric uses of tests were described and the relevance of the edumetric dimension for measuring student learning gains, especially in the context of individualized instruction involving multiple learning mode options, was clarified. Also, the procedures for edumetric reliability and validation assessment…

This document is an English-language abstract (approximately 1,500 words) of a book which purposes to elucidate the connection between the development of pupils and their assimilation of knowledge and habits in the experimental grades of a new system of elementary education. Various methods of investigation were used: observation during lessons,…

The conceptual basis for using individual expectancy scores as a means for determining the success of instruction is presented. An expected gain score is computed for each student, based on a pretest score. The assumption is made that without a change in the learning environment the student will continue to gain at his previous average rate. The…

The four main approaches to measuring treatment effects in schools; raw gain, residual gain, covariance, and true scores; were compared. A simulation study showed true score analysis produced a large number of Type-I errors. When corrected for this error, this method showed the least power of the four. This outcome was clearly the result of the…

This study had the purpose of comparing the effects of two approaches in teaching mathematics to secondary special education students. The study attempted to answer the following questions: (1) Were there significant differences between group means of mathematics achievement test scores for students in a diagnostic-prescriptive mathematics program…
