Some methodological issues in the study of levels of knowledge are reviewed, and needs for further research are explored, drawing on an analysis of 12 studies reported since the late 1970s. In the 12 studies, 16 quantitative experiments were conducted. These were assessed for internal and external validity. Analysis revealed some shortcomings in…

This report examines the limitations of research that has been conducted on the effects of retention and social promotion. It reexamines seven research studies that provide strong evidence based on strong methodology that includes the following three characteristics: (1) the studies identify the basis of comparison, that is, whether they are…

Currently available measures of self-efficacy described in educational and psychological research literature were cataloged and reviewed after a literature search.
