Science Instruction for Students with Learning Disabilities: A Meta‐Analysis     

William J. Therrien  Jonte C. Taylor  John L. Hosp  Erica R. Kaldenberg  Jay Gorsh 《Learning disabilities research & practice》2011,26(4):188-203

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   

国家认同的生成考察:政治仪式的观念再生产视域     

曾楠 《安徽师范大学学报(人文社会科学版)》2021,49(1):33-39

国家认同作为一种社会意识,是从"我"到"我们"的共属一体的心理想象,是对"我们同属于一个共同体"的归属认同.政治仪式作为国家观念的仪式化表达,通过观念赋予→再造→共享→延展的完整流程,实现观念的生产与再生产.政治仪式的观念再生产直接联结个体的价值定位与文化归属,是国家认同的重要载体.考察东西方历程,政治仪式的观念再生产历经了专制型文化预设下观念再生产、消费型文化预设下观念再生产、民主型文化预设下观念再生产的变化历程,国家认同相应呈现虚妄与假象、萌发与隐忧、生长与勃兴的不同表征.从价值形态变迁的理论立基审视,绝对价值极致化、价值多元主义、价值共识融通是政治仪式观念再生产呈现相应样态的理论渊源.  相似文献

Symbolic Management of the Degree of Information Security by Integer Splitting     

V. L. Stefanuk  A. H. Alhussain 《Scientific and Technical Information Processing》2017,44(6):450-454

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   

Educational Programs for Elementary Students with Learning Disabilities: Can They Be Both Effective and Inclusive?     

James McLeskey  Nancy L. Waldron 《Learning disabilities research & practice》2011,26(1):48-57

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

Quality of Life of Children with Learning Disabilities: A Comparison of Self‐Reports and Proxy Reports          下载免费PDF全文

Halis Sakız  Zeynep Hande Sart  Bengü Börkan  Barış Korkmaz  Nalan Babür 《Learning disabilities research & practice》2015,30(3):114-126

This study aimed to explore how children with learning disabilities (LD) perceive their quality of life (QoL) and to compare self‐reports and proxy reports regarding their QoL. Children with LD, their typically developing peers, their parents and teachers responded to the child, parent, and teacher forms of KINDL^R Questionnaire for Measuring Health‐Related Quality of Life (Ravens‐Sieberer & Bullinger, 1998). Findings showed that children with LD reported significantly lower QoL scores than those reported by typically developing peers. Intraclass correlation coefficients (ICCs) and t‐test results showed that agreement between child reports and parent‐proxy reports was either low or moderate on each QoL dimension. Findings of the study may be used to raise awareness regarding the social and educational needs of children with LD in Turkey.  相似文献

The effect of smartphones and playing video games on decision-making in soccer players: A crossover and randomised study     

Leonardo S. Fortes  Dalton De Lima-Junior  Lenamar Fiorese  José R. A. Nascimento-Júnior  Arnaldo L. Mortatti  Maria E. C. Ferreira 《Journal of sports sciences》2020,38(5):552-558

ABSTRACT

The objective of this study was to analyse the effect of the use of social networks in smartphones or playing video games on the passing decision-making performance in professional soccer athletes. Participants were 25 male professional soccer athletes (mean ± SD: age 23.4 ± 2.8 years). The participants performed three randomised conditions divided into three groups: control (CON), smartphone (SMA), and video game (VID). Before and after each experimental condition, the Stroop Task assessed the level of induced mental fatigue. Then, the athletes performed a simulated soccer match. A CANON® camera recorded the matches for further analysis on passing decision-making performance. A group effect was identified (p < .01) with impairment on passing decision-making performance for the SMA (p = .01, ES = 0.5) and VID (p = .01, ES = 0.5) conditions. We concluded that the use of social networks on smartphones and/or playing video games right before official soccer matches might impair the passing decision-making performance in professional soccer athletes.  相似文献
