Although science has received much attention as a political and educational initiative, students with learning disabilities (LD) perform significantly lower than their nondisabled peers. This meta‐analysis evaluates the effectiveness of instructional strategies in science for students with LD. Twelve studies were examined, summarized, and grouped according to the type of strategy implemented. Effect sizes (ES) were calculated for each study. Across all studies, a mean ES of .78 was obtained, indicating a moderate positive effect on students with LD science achievement. Findings also align with past reviews of inquiry‐based instruction for students with special needs, indicating that students with LD need structure within an inquiry science approach in order to be successful. Additionally, results suggest that mnemonic instruction is highly effective at increasing learning disabled students' acquisition and retention of science facts. 相似文献

This article focuses on counseling research in the community college context. The article suggests the need for a robust community college knowledge base, describes some limitations of the current community college literature, and suggests a framework for more effective work in this area. The authors’ own experiences and selected examples of published studies are used as illustrations of the hurdles encountered and solutions available when examining counseling theories, practices, and outcomes in 2‐year settings. 相似文献

This experimental study examines an online module designed to increase student competence in oral citation behavior using a mastery training strategy. Students in the experimental condition provided complete citations at a higher rate and provided more citation information for traditional and web-based sources compared with a control group without required training. Although subjective norms set by instructors also influence citation behavior, the general trend depicted was that students completing the required module training performed more complete citations. Implications for student learning, mastery instruction, and course assessment were considered to be generally beneficial and at minimal cost. 相似文献
