Mapping beliefs about teaching to patterns of instruction within science,technology, engineering,and mathematics

In this paper, we identify beliefs about teaching and patterns of instruction valued and emphasized by science, technology, engineering, and mathematics faculty in higher education in the USA. Drawing on the notion that effective teaching is student-centered rather than teacher-centered and must include a balance of knowledge-, learner-, community-, and assessment-centered learning environments; we use qualitative interview data to explore how faculty's reported beliefs about teaching are associated with their consideration of these four types of environments. Findings indicated that although a range of beliefs about teaching emerged, most were firmly located in knowledge-centered learning environments, with little or no focus on the remaining three learning environments. Furthermore, even patterns of instruction that were heavily student-centered were situated within a knowledge-centered learning framework. We argue that for student-centered instruction to be truly successful, faculty must consider all four learning environments in crafting and facilitating the classroom environment.     

Computing in the curriculum: Challenges and strategies from a teacher’s perspective

Computing is being introduced into the curriculum in many countries. Teachers’ perspectives enable us to discover what challenges this presents, and also the strategies teachers claim to be using successfully in teaching the subject across primary and secondary education. The study described in this paper was carried out in the UK in 2014 where teachers were preparing for the mandatory inclusion of Computing into the curriculum. A survey was conducted of over 300 teachers who were currently teaching Computing to elicit their perspectives on challenges and strategies. From the analysis of the data, extrinsic and intrinsic challenges were identified for both teachers and students. In addition, a variety of pedagogical strategies were recommended by teachers from their own practice. In categorising approaches taken by teaching to support students five key themes emerged: unplugged type activities, contextualisation of tasks, collaborative learning, developing computational thinking, and scaffolding programming tasks. Further investigation could support whether these strategies can alleviate the challenges of teaching and learning of Computing for students and teachers. In particular developing student resilience in Computing is seen as a challenge while not many strategies are suggested. The results of this study will be useful for teachers who are new to the teaching of Computing.

Beliefs about teaching and uses of technology among pre‐service teachers

In the current learning environments, technology is integrated in different ways. Teachers acting in the capacity of main change agents bring with them beliefs about teaching which effects their use of technology in the classroom. This study aims to examine the possible relationship between teachers' beliefs about teaching and uses of technology. Unlike past research on this issue, the results from this study show that belief in constructivist teaching correlates significantly with both constructivist and traditional uses of technology. However, a belief in traditional teaching is only significantly correlated (negatively) with constructivist use of technology. Implications for teaching training and future research are discussed.     

Teaching without a blackboard and chalk: conflicting attitudes towards using ICTs in higher education teaching and learning

This article, derived from a three-year ethnography of distributed medical education provision in a Canadian university, explores the ways in which information and communication technologies are used by teachers and students in their everyday work within technologically rich teaching environments. The environments being researched are two university campuses: a campus at the main university site and a satellite campus in a neighbouring province. The article seeks to contrast dominant, institutional discourses of technology use in higher education teaching with the everyday practices of staff and students. The article concludes that there is a gap between policy and practice in distributed education and that the teaching and learning experience and context of staff and students in different sites need to be analysed in depth, in terms of: whether the experience of learning across sites can be positioned as being comparable; the extent to which technology ameliorates learning and teaching; and understanding the work done by staff.
