A summary of the purpose of the project, a discussion of experiment design, some statistical analysis of test results, and implications are included in this article. Attempting to determine which of three audio-assistance systems--the audio-active, audio-record language laboratory, or the classroom tape recorder--is most effective in foreign…

Student achievement data from 92 school districts in South Carolina were analyzed to determine which variables were most likely to affect educational quality. Fourth and seventh grade samples were examined to determine the effects on achievement when the shared variation between achievement and the context variables was removed. The data included…

This study considered the relationships among five variables of school-community relations (access, communication, involvement, participation, and conflict resolution); measured the general relationship between parents' perceptions of school-community relations and their children's academic achievement; measured the contribution of each of the…
