This paper discusses the findings of a collective case study of two junior colleges in Singapore. It aims to identify and describe the scaffolding strategies used by teachers to engage students in computer‐mediated lessons. For students to engage in the learning process, they need to be equipped with the learning strategies and see the relevance of the concepts and principles presented. By employing methods such as observations, focus group discussions with students and face‐to‐face interviews with teachers, an account of how scaffolding strategies are used in computer‐mediated lessons is generated. The account identifies and describes four categories of scaffolding strategies: orienting activities, peer interactions, prompts and modelling. Copyright © 2004 Taylor & Francis.
