Altitude and wind effects on long jump performance with particular reference to the world record established by Bob Beamon

An analysis of long jump performance, including both the approach and aerial phases, is applied to Bob Beamon's legendary leap at the Mexico City Olympic Games of 1968. It is shown that the combined effects of altitude and wind assistance yielded an increment in the length of the jump of about 31 cm, compared to a corresponding jump at sea level under still air conditions. The main factor is shown to be the increased sprinting speed attained under favourable conditions of wind and altitude.     

Towards a Comprehensive Account of Effective Thinking

Due to its strong focus on reasoning and argumentation, critical thinking lacks the breadth required of a comprehensive account of higher order thinking. In particular, critical thinking does not promote reflection on the underlying problems or situations that people think about. This paper reviews various proposed additions to and reorientations of the critical thinking paradigm. It presents a conceptual framework that encompasses the most promising extensions as topics in a broadened account of higher order thinking. This account can be understood as an elaboration of problem solving along two dimensions: Problem types, which are generic thinking situations; and problem solving functions, which are generic thinking tasks. The proposed topic-level account of higher order thinking offers a greatly enlarged view of what should be taught in general thinking skills programs.     

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.
