title: Developing teaching knowledge in primary technology

authors: Moreland, Judy

abstract: How might a teacher set about teaching five-year olds how to design successfully? What could a teacher do when their students are unable to resolve construction problems? How do teachers teach technological concepts in a subject that is very practical? The InSiTE project (Cowie, Moreland, Jones, & Otrel-Cass, 2008)1 aimed to investigate these kinds of questions; that is, those related to teachers teaching technology education in primary schools. Over three years we explored teacher knowledge, its sources and development, and the ways it was used by primary teachers so that their students had worthwhile learning experiences in both technology and science education. In this article we discuss the implications for teaching of a subject-specific planning framework.

title: Using micro-mechanical modelling to predict short-fibre composite properties in computer-aided design of sporting equipment

authors: Ewart, Paul

subjects: flexural modulus

abstract: Computer-aided design (CAD) of sporting equipment requires knowledge of the mechanical properties of proposed materials. The mechanical properties of composite materials are often not as simple to obtain as those of conventional materials, in which case micro-mechanical modelling could be used in conjunction with CAD software. A micro-mechanical model was used to predict the flexural modulus of composite materials, based on the assumption of partial interfacial adhesion between composite components. It was found that the partial adhesion model was both practical and consistently accurate. The partial adhesion model accounted for adhesion between components by considering an ‘effective shear value’ at the interface. The model was compared to experimental data for glass, wood and carbon-fibre reinforced polyethylene. It was shown that the adhesion coefficient ranged between 0.1 for carbon fibre, 0.5 for glass fibre and 0.8 for the wood fibre composites. It was shown that using micro-mechanical modelling to predict composite mechanical properties, as opposed to simulating the comprehensive composites structure, computer processing time and file size can be reduced with little compromise in simulation accuracy.

title: Hei Āwhina Mātua: A kaupapa Māori response to behaviour

authors: Berryman, Mere

abstract: Hei Āwhina Mātua (strengthening parents and other adults), a kaupapa Māori research and development project, sought to capitalise on the strengths available within both whānau and teachers so that both groups could take joint responsibility for students' learning and behaviour. This required professionals trained in delivering learning and behavioural programmes for individual students working in culturally responsive and collaborative ways with adults, whānau, teachers and community members, This chapter returns to this study to reconsider the key findings.
