The biasing effects of a pretest on subsequent post-test results were investigated in two experimental studies. In general, the results argue for using designs without pretests. (Author/JKS)

This pilot study investigated if goal setting with curriculum-based measurement (CBM) was effective in increasing student awareness of goal knowledge and if students could set realistic daily reading goals. Nineteen 6th and 7th grade students with learning disabilities participated in a goal setting treatment group or a control group. During the…

This study investigated whether the software Virtus WalkThrough Pro could be used to enhance middle school children's spatial ability as measured by the Paper Folding, Mental Rotations, and Eliot-Price Tests. The study also investigated whether the use of this software impacted males differently than females, or users with high spatial ability…

This study is part of a larger research project investigating the effects of using metalinguistic reflection integrated into a communicative class as a way of promoting second language acquisition among French-speaking Grade six (i.e. 10-11 year old) ESL learners (n=81). Even though metalinguistic reflection is thought to promote language…

This article reviews research on the achievement outcomes of mathematics programs for middle and high schools. Study inclusion requirements included use of a randomized or matched control group, a study duration of at least twelve weeks, and equality at pretest. There were 102 qualifying studies, 28 of which used random assignment to treatments.…

This study aims to assess the impact of hypermedia designing as a cognitive tool on knowledge acquisition and retention in comparison to traditional instruction. A pretest-posttest control group design was used. The study included 48 second-year preservice computer teachers who enrolled in "Instructional Technology and Material…

This project was initiated in order to evaluate two literacy and science integrated instruction units, "Shoreline Science" and "Terrarium Investigations," designed by the Lawrence Hall of Science "Seeds of Science/Roots of Reading" Project ("Seeds/Roots"). We examined how the integrated units affect student…

This study aims to assess the impact of hypermedia designing as a cognitive tool on knowledge acquisition and retention in comparison to traditional instruction.
