Teaching science skills and knowledge to students with developmental disabilities: A systematic review     

Magdalena M. Apanasionok  Richard P. Hastings  Corinna F. Grindle  Richard C. Watkins  Andreas Paris 《科学教学研究杂志》2019,56(7):847-880

A comprehensive review of the literature was conducted to identify current practice on teaching science to students with intellectual disability (ID) and/or Autism Spectrum Disorder (ASD) in relation to two review questions—students' science outcomes and students' and teachers' experiences of the interventions. Six databases related to education, psychology, and science were systematically searched. A detailed protocol can be viewed on PROSPERO (registration number: CRD42017057323). Thirty studies were identified that reported on science interventions and 20 on student/teacher experiences of the interventions. The majority of the studies targeted science vocabulary and concepts. Other targets included inquiry skills and comprehension skills. The majority of the interventions used components of systematic instruction (n = 23). Five studies focused on self-directed learning and two on comprehension-based instruction. Students and teachers reported positive experiences of the interventions. The findings suggest that components of systematic instruction in particular might be effective in teaching science content to students with ID and/or ASD. Further research is needed to explore the effectiveness of identified interventions on teaching more complex science skills and with students with severe disabilities. Some limitations related to the search strategy are highlighted.  相似文献   

‘I'm ready for a new chapter’: The voices of young people with autism spectrum disorder in transition to post-16 education and employment     

Carolina Gaona  Olympia Palikara  Susana Castro 《British Educational Research Journal》2019,45(2):340-355

This study explores the views and experiences of 12 young people with autism spectrum disorder (ASD) in transition to post-16 education and employment, in light of the changes introduced by the new special educational needs and disability (SEND) legislation in England. The extension of provision until the age of 25, and the introduction of person-centred education, health and care (EHC) plans, have given a significant place to the views of young people with SEND and their families. The views, wishes and aspirations of young people must be captured in the newly developed plans, reflecting the statutory requirement for local authorities to systematically record these in a biopsychosocial way, focusing on participation and well-being. Twelve semi-structured interviews were conducted with young people with ASD attending specialist settings or receiving specialist support under the new EHC plans. These were analysed inductively, through thematic analysis. The findings suggest that at the time of transition, young people with ASD want to become increasingly more independent, present ambivalent feelings about their future and acknowledge the relevance of support systems in their lives. Implications for practice and future research are discussed, in light of the new English policy context.  相似文献   

荧光光谱法研究黄豆苷原与牛血清白蛋白的相互作用     

宋胜梅  罗小芹  徐茂田 《商丘师范学院学报》2011,27(3):58-62

用荧光光谱法在pH7.4的PBS中研究了黄豆苷原（Daidzein,Da）与牛血清白蛋白（bovine serum albu-min,BSA）的相互作用.结果表明Da可静态猝灭BSA的内源荧光,温度升高时受动态猝灭的影响变得明显.二者之间的结合位点数约为1.5,315 K、310 K,300 K和290 K时的表观结合常数分别为5.44×104L.mol-1,5.70×104L.mol-1,5.29×104L.mol-1和5.69×104L.mol-1.焓变为0.2969 kJ.mol-1,熵变为91.78为J.mol-1.K-1,各温度下的自由能变均小于零,热力学参数表明二者之间主要靠静电力发生作用,熵变对反应过程具有较大贡献,且反应是自发过程.同步荧光光谱表明Da的加入改变了BSA的构像,使色氨酸残基的微环境亲水性增强.本研究对于阐明Da与蛋白的相互作用机理具有借鉴意义.  相似文献

刘桂玲 《雁北师范学院学报》2011,27(4)

基于回弹法全国测强曲线,通过工程实例研究了结构混凝土抗压强度的回弹法无损检测试验方法,并与钻芯法混凝土强度检测试验方法进行了对比。结果表明,应用回弹法全国测强曲线,推定大同地区结构混凝土抗压强度是可行的。但推定强度值要稍高于其实际强度值。  相似文献

Getting good at small talk: student-directed learning of social conversation skills     

Veerle Garrels 《欧洲特需教育杂志》2019,34(3):393-402

For students with autism spectrum disorders (ASD), learning social skills is an intricate but essential task to facilitate social inclusion and participation. Limited research is available on social skills interventions for adolescents with ASD and intellectual disabilities (ID). This article presents a case study that illustrates how the Self-Determined Learning Model of Instruction was used to improve self-chosen social conversation skills in a Norwegian 14-year old student with ASD and mild ID. This case study illustrates that, also for students with ASD and ID, giving them the opportunity to set personally relevant goals may improve their autonomous motivation, thereby increasing the likelihood of goal attainment.  相似文献
