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 summarises previous academic research into university education, distinguishing between arguments for and against improving access. Several views are summarised, including structural‐functionalism, which claims that powerful social groups maintain their status and income, and human capital theory, which focuses on employee productivity. Almost all viewpoints discussed in this article support meritocracy. UK universities differ in their openness to people from disadvantaged backgrounds. Many universities, referred to here as ‘inclusive’, deserve credit for encouraging disadvantaged people to become students; in contrast, ‘exclusive’ universities tend to have fewer disadvantaged students than expected. There are barriers facing disadvantaged students, including unequal access to universities, which can at least partly be explained by private schools for rich pupils and financial burdens at university causing some students to take paid work (reducing time available for study). The UK spends less per student on universities than the world average and less than half as much as some European countries. The UK Government could increase university funding, concentrating on universities that are most inclusive and that tend to have the largest problems in affording sufficient staff and teaching facilities. This investment would give long‐term benefits to the UK economy.  相似文献

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
