This study compares pauses, repetitions and recasts in matched task interactions under face-to-face and computer-mediated conditions. Six first-year English undergraduates at a Turkish University took part in Skype-based voice chat with a native speaker and face-to-face with their instructor. Preliminary quantitative analysis of transcripts showed…

This paper focuses on the scientific dialogue of a small group following an experiment on motion under gravity. This research was designed to investigate ways in which practical activities can be used to foster links between upper elementary children's spontaneous concepts and Newtonian mechanics. Implicit in this is the notion that teaching…

Discussion about and reflection upon observations which produce cognitive conflict have frequently been promoted as a strategy to enhance conceptual development in science classrooms. As part of the Practical Mechanics in Primary Mathematics project, teachers were urged to elicit children's views and attempt to establish what is now called…

This paper focuses on the evidence of learning in children engaged in small-group discussion with a teacher. The children are considered to have learned if they show progress in the explanations they make, the language they use in the dialogue, or the understanding they show of the dialogue. Motives of the participants in this dialogue are…
