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 paper demonstrates the application of module arithmetic for controlling the level of information security by a new technique referred as integer splitting. The basic definitions and concepts of the method are provided. The mathematical function of arising transformation is described in detail; its properties were studied and the basic theorems were proven that justify the use of splitting in practical applications. An active system was designed and characteristic cases of its operation are considered. 相似文献

A Campus-Wide Investigation of Clicker Implementation: The Status of Peer Discussion in STEM Classes
Justin D. Lewin Erin L. Vinson MacKenzie R. Stetzer Michelle K. Smith 《CBE life sciences education》2016,15(1)
At the University of Maine, middle and high school teachers observed more than 250 university science, technology, engineering, and mathematics classes and collected information on the nature of instruction, including how clickers were being used. Comparisons of classes taught with (n = 80) and without (n = 184) clickers show that, while instructional behaviors differ, the use of clickers alone does not significantly impact the time instructors spend lecturing. One possible explanation stems from the observation of three distinct modes of clicker use: peer discussion, in which students had the opportunity to talk with one another during clicker questions; individual thinking, in which no peer discussion was observed; and alternative collaboration, in which students had time for discussion, but it was not paired with clicker questions. Investigation of these modes revealed differences in the range of behaviors, the amount of time instructors lecture, and how challenging the clicker questions were to answer. Because instructors can vary their instructional style from one clicker question to the next, we also explored differences in how individual instructors incorporated peer discussion during clicker questions. These findings provide new insights into the range of clicker implementation at a campus-wide level and how such findings can be used to inform targeted professional development for faculty. 相似文献

One of the most controversial issues in special education over the last 40 years has been the extent to which students with learning disabilities (LD) should be educated in general education classrooms. Recent mandates in federal law requiring that all students with disabilities have access to the general education curriculum and make adequate yearly progress relative to this content have intensified this debate. In this article, a brief summary of research regarding the nature of instruction that produces significantly improved educational outcomes for students with LD is provided. This is followed by a review of research related to the delivery of this high‐quality instruction in inclusive, general education classrooms and in resource settings. We conclude that this research provides the foundation for reconsidering full inclusion and how services are delivered for elementary students with LD. 相似文献

在我国转入高质量发展的新阶段,国民教育发展对社会经济持续发展和国际竞争力提升起着极为关键的作用.结合最新的全国人口普查公报以及巴罗和李整理发布的世界主要国家人口教育统计资料,系统分析我国人口教育发展现状、历史轨迹和相对国际位置,探讨现阶段制约我国人口教育发展的结构性问题和主要矛盾,发现目前我国人口的整体教育水平和发展速度在世界各国中处于中等,且近年来人口教育发展速度出现减缓的迹象.制约我国教育持续快速发展的关键在于,各级教育发展的结构性失调和省际教育发展不平衡等问题.新时期,推动我国人口教育持续快速发展,应当着力解决教育发展中存在的突出问题与矛盾,通过制度建设和文化引导在全社会树立重视教育的理念,同时,改革和完善教育体系中的制度安排.根据新阶段人才培养的需要,拓展义务教育年限,有效降低由于制度设计而引发的学生在升学过程中逐级流失带来的损耗,提升各级教育发展的协调性和可持续性;将分省份管理和负责的制度安排转化为制度优势,倡导各省份因地制宜、设计符合省情的教育教学设置和规划,避免在制度设计中不切实际的"一刀切". 相似文献
