FACILITATING PROSPECTIVE SECONDARY MATHEMATICS TEACHERS LEARNING OF PROBLEM SOLVING University of Calgary This study explored two "self-study of personal experience" approaches to determine their effectiveness in helping prospective secondary mathematics teachers to develop mathematical problem-solving knowledge for teaching. Participants s e problems and recorded their processes using two different approaches.Both approaches were found to be helpful for their learning, but one was more effective in highlighting taken-for-granted cognitive aspects of the process, thus producing a more realistic view and model of problem solving as a way of thinking mathematically. The study offers support for the use of a combined approach in teacher education to provide a rich basis of personal experience to make sense of problem solving.
