Reliability and validity are two characteristics that must be considered whenever information about student achievement is collected. However, those characteristics--and the methods for evaluating them--differ in large-scale testing and classroom testing contexts. This article presents the distinctions between reliability and validity in the two…

Based on the results of a generalizability study of measures of teacher knowledge for teaching mathematics developed at the National Center for Research on Evaluation, Standards, and Student Testing at the University of California, Los Angeles, this article provides evidence that teachers are better at drawing reasonable inferences about student…

In many school districts, the pressure to raise test scores has created overnight celebrity status for formative assessment. Its powers to raise student achievement have been touted, however, without attending to the research on which these claims were based. Sociocultural learning theory provides theoretical grounding for understanding how…

The accuracy of achievement test score inferences largely depends on the sensitivity of scores to instruction focused on tested objectives. Sensitivity requirements are particularly challenging for standards-based assessments because a variety of plausible instructional differences across classrooms must be detected. For this study, we developed a…

Proponents of standards-based reform claim that student achievement testing increases accountability and allows for greater instructional consistency. Performance across schools, boards, provinces, and even countries internationally can be compared and contrasted with the aim of identifying exemplary teaching practices. Teachers can also use…

At the 1970 meeting of the American Educational Research Association a symposium, jointly sponsored by the National Council on Measurement in Education, was presented on the topic "Criterion-Referenced Measurement: Emerging Issues." The following papers were presented: "Instructional Technology and the Measurement of Learning Outcomes: Some…

This publication continues the annual series of bulletins begun in 1950 as a cooperative undertaking between the National Association for Research in Science Teaching and the Office of Education. The present bulletin summarizes and interprets the research in science education from July 1956 to July 1957. The improvement of teaching in science, as…
