Brief
Problem solving is considered by many Physics instructors as a learning opportunity intended to promote both conceptual understanding as well as the development of expert-like approaches to cope with novel problems. Yet, traditional instructional practices in the physics classroom (both in high school and in college) often focus on the procedural aspects of solving familiar problems and do not materialize the learning opportunity to its full potential. A series of research and development activities took place, involving three interrelated research foci: a) the study of students' learning processes in the context of problem solving; b) the study of views and norms of physics instructors related to problem solving; and c) research based design of instructional resources and professional development frameworks to support physics teachers in directing their work to promote reflective habits of mind in physics problem solving.
Research focus 1 characterizes the processes by which learners refine their conceptual understanding when they reflect on erroneous solutions and study worked out examples. In particular, we studied students' capacity to self-repair (acknowledge and resolve possible conflicts between a scientifically acceptable approach/solution to a problem and the student's own approaches) when reflecting on their own solutions to a problem. We compared students' self-repair in the context of self-diagnosis tasks in which learners are provided with time, credit and resources to search for, detect and explain errors in their own solutions. The study of these tasks highlights students' difficulties in self-diagnosing their solutions, shows that with appropriate external support students with low prior knowledge benefit the most from self-diagnosis activities, and suggest the kinds of external support needed to help students to self-diagnose their solutions (see papers 1-5 in the reading list below).
Research focus 2 characterizes instructors' practices and attitudes towards the design of instructional in the context of problem solving (e.g. the design of problems, worked out examples and assessment). The research showed that college faculty views align with the view of cognitive researchers regarding the learning habits through which students develop conceptual understanding via problem solving. However, they did not perceive it as their role to develop these learning habits. Conflicting sets of values were also identified for teaching assistants (in the US) and with high school teachers' first enactment of troubleshooting activities (see papers 6-14 in the reading list below).
Research focus 3: Research-based development of instructional strategies and materials to support physics teachers in promoting reflective habits of mind in physics problem solving. In particular, we examined the impact of an educational intervention containing a series of computerized troubleshooting activities that support students in diagnosing teacher made incorrect solutions. The student is required to perform a diagnosis anchored in physical principles and concepts and the system provides feedback to students on their diagnosis. The study focused on high school physics students, and the activities were adapted to the contents of the advanced level high school physics syllabus in Israel. Pairs of students engaged in the activities were found to discuss criteria that differentiate between scientifically accepted interpretations and alternative interpretations of the concepts and principles discussed. A yearlong intervention with repeated computerized troubleshooting activities was found to enhance students' inclination and ability to self-repair in comparison to a more traditional self-diagnosis intervention. Another direction is the design of professional development frameworks for teachers (see papers 15-19 in the reading list below).
