Peer Teachers With Autism Teaching 3D Modeling

ABSTRACT

Few autism programmes address the needs of adolescents and young adults, and those that do are unlikely to include individuals with autism in the design and evaluation of the programme. This study involved nine youth with autism (ages 16–25) in the development and evaluation of a peer teaching programme where they taught three-dimensional modelling to other students with autism spectrum disorder. The methodology was participant-oriented research where the students with autism were co-designers and programme evaluators in the research. This approach highlighted their unique strengths and abilities and shifted the power such that they were leaders and not simply the recipients of knowledge from instructors. Four themes emerged through the qualitative analysis of the students’ perceptions of the peer teaching programme: 1) the meaning of peer teaching, 2) motivations for peer teaching, 3) challenges and 4) coping with the challenges of the role.

Local language a medium of instruction: challenges and way forward

The paper reports on a participatory action research study conducted in six rural primary schools in Uganda in 2013 to establish why children taught in the local language had difficulties in reading and writing. Findings through interviews, focus group discussions, reviews of exercise books and lesson observations indicated that though it was easier for pupils to learn the concepts in the local language; challenges ranging from poor translation, inadequate teachers’ language proficiency, lack of instructional materials, high pupils’ enrolment, lack of administrative support and teacher-centred approach of teaching, affected pupils’ learning to read and write. Participants recommended adopting the child-centred pedagogy, incorporating instructional materials, conducting continuous assessment and recording pupils’ competencies attained in reading and writing. Teachers need to engage more in Participatory action research in order to reflect on their practices and pupils’ learning, and collaboratively decide what works best and what needs improvement in their classrooms.     

A response to strategies and tactics through participatory action research in a developmental mathematics course

This paper explores the value of participatory action research in a community college developmental mathematics course. The authors used the framework of critical mathematics education in order to understand the critical conversations of students about their learning experiences, and also to help the instructor of the course develop the curriculum that attended to student experiences. The authors also draw on Michel de Certeau’s ideas about strategies and tactics to understand how students responded to their past learning experiences. Data results from the study show that students can gain a better understanding of their own learning and subsequently develop deeper content knowledge when they are more involved in the teaching and learning process. Lastly, the authors conclude that as adult learners grow in their understanding of the learning processes and of the content being presented, participatory action research can play an important role in the entire development of thinking and intellectual engagement.

现代职业教育体系的多中心建设

在职业教育深度改革和投资主体多元化的环境下,多中心建设是一种多边互惠共赢的发展建设模式。然而各主体行动逻辑的迥异构成了阻碍现代职业教育体系建立、健全的桎梏和顽疾。因此,从建设主体、建设路线以及制度创新三个方面着手提出现代职业教育体系的多中心建设思路,将为推进现代职业教育体系的优化、强化、活化、实化、深化提供有益借鉴。     

论世界一流大学建设的中国道路——国家行动与大学自主办学的耦合

世界一流大学的建设道路,具有由大学运行与发展的共同逻辑和基本规律决定的共性,也具有由大学运行与发展的生活环境和影响因素决定的个性,呈现出以共性与个性辩证统一为基础的多样性。中国特色世界一流大学建设走中国道路,既有理论层面的可能性,又有现实层面的必要性,还有实践层面的现实性,即具有合目的性与合规律性的必然性。中国特色世界一流大学建设走中国道路,既离不开作为战略规划、制度供给、资源配置、考核评价、监督管理以及信息服务主体的国家的强力推动、顶层设计以及统筹谋划,也离不开作为基层行动主体的大学的自主探索、自觉行动以及自发建构,即要走国家行动与大学自主办学耦合之路。     

矩形管柱和H形钢梁端板连接分析

高频焊接矩形管生产效率高,抗扭性能好,平面外刚度大,根据需要内部可充填混凝土以提高抵抗局部屈曲的能力,比焊接H型钢的轻钢厂房有更好的经济性。为提高梁柱连接节点的承载力、减小节点变形,需在节点区外包槽钢。本文分析了节点区不同厚度、不同形式外包槽钢和不同的柱内加劲肋设置等对节点强度和刚度的影响,得出了满足刚性连接要求的节点区外包槽钢厚度计算公式。研究了柱加劲肋、螺栓排列、螺栓数目、槽钢宽度和槽钢下伸长度等的影响。建议了箱形柱柱顶与梁上翼缘齐平,槽钢与梁端板等厚,槽钢向上伸出长度以满足安装一排高强螺栓的要求,并设置三角形加劲肋与柱顶盖板和槽钢焊接,箱形柱顶和槽钢内面满焊的节点形式。分析表明这种节点有很高的刚度和强度,能满足刚性连接的要求。
