The meta analysis explored how measuring special education student progress toward long-term vs. short-term goals affects achievement outcomes. Results indicated that when progress toward long-term goals was measured, unbiased effect sizes were higher than on probelike outcomes; when progress toward short-term goals was measured, the reverse was…

This meta-analysis investigates the effects on achievement of type of graphing paper employed in displaying student performance data collected over time. Ongoing curriculum-based measurement systems employing Data-Based Program Development (DBPD) provide a data source of 16 controlled studies with 17 effect sizes. A total of 3,494 subjects…

This article presents a meta-analysis of the effects of examiner familiarity/unfamiliarity on children's performance during individual testing. Data came from 22 controlled studies involving 1489 subjects. In a typical study, the effect of examiner familiarity raised test performance by .35 standard deviations. Differential performance favoring…

Based on data from 22 controlled studies, this article presents a meta-analysis of the effects of examiner familiarity on children's test performance. It was found that examiner familiarity raised scores especially when subjects were: (1) of low socioeconomic status; (2) tested on difficult tests; and (3) knew the examiner for a long duration.…

This meta-analysis explored how measuring student progress toward long vs. short-term goals affects achievement outcomes. Twenty-one controlled studies were coded in terms of measuring method (toward long- vs. short-term goals) and type of achievement outcome (probe-like vs. global achievement test). Analogues to analysis of variance conducted on…
