The causal effects of time spent in learning (TSL) and time needed for learning (TTL) on the reading and spelling achievement of 171 fourth and fifth grade students were investigated. TTL contributed significantly to achievement, and its direct effect was greater than TSL. Results also support a Carroll's learning model. (Author/BS)

A review of research on time on task and length of school day or year reveals that time is not the only variable significantly related to student achievement. Research indicates that increasing time in school will not automatically increase student achievement or raise standardized test scores. Other variables such as corrective and immediate…

Two approaches to testing student achievement are discussed: (1) traditional standardized tests; and (2) testing achievement on an instructional unit. Content validity is a major problem with standardized achievement tests. Even though test publishers typically consider a number of curriculum guides and textbooks in producing a test which is…

This study investigated the effect of reward structure and group ability composition on small group computer-assisted instruction. Junior high school students practiced algebra in mixed-ability or uniform-ability groups, and rewards were based on individual performance, group performance, or a combination of both.

This descriptive study investigates the variability in the curriculum pacing decisions of classroom teachers. The effects on the reading achievement and performance gains of first and second grade students in a compensatory education program program are examined. Data were collected from: (1) the Metropolitan Readiness Test results used to select…
