Teaching and Learning about Force with a Representational Focus: Pedagogy and Teacher Change

A large body of research in the conceptual change tradition has shown the difficulty of learning fundamental science concepts, yet conceptual change schemes have failed to convincingly demonstrate improvements in supporting significant student learning. Recent work in cognitive science has challenged this purely conceptual view of learning, emphasising the role of language, and the importance of personal and contextual aspects of understanding science. The research described in this paper is designed around the notion that learning involves the recognition and development of students’ representational resources. In particular, we argue that conceptual difficulties with the concept of force are fundamentally representational in nature. This paper describes a classroom sequence in force that focuses on representations and their negotiation, and reports on the effectiveness of this perspective in guiding teaching, and in providing insight into student learning. Classroom sequences involving three teachers were videotaped using a combined focus on the teacher and groups of students. Video analysis software was used to capture the variety of representations used, and sequences of representational negotiation. Stimulated recall interviews were conducted with teachers and students. The paper reports on the nature of the pedagogies developed as part of this representational focus, its effectiveness in supporting student learning, and on the pedagogical and epistemological challenges negotiated by teachers in implementing this approach.     

University teacher competencies in a virtual teaching/learning environment: Analysis of a teacher training experience

This paper attempts to shed light on the competencies a university teacher must have in order to teach in virtual learning environments. A teacher training experience was designed by taking into account the methodological criteria established in line with previous theoretical principles. The main objective of our analysis was to identify the achievements and difficulties in a specific formative experience in order to assess the suitability of this conceptual-methodological framework for the design of training proposals aiming to develop teachers’ competencies for virtual environments in higher education.
