This study explores how a proving task with technology can be designed to develop students’ strategic knowledge of how to construct alternative proofs to the same problem, and how the designed task enriched their strategic knowledge in proving in the context of geometrical proof. The designed task had three components; open problem with flow-chart proofs, learning environment with web-based proof learning support system, and process of expressing strategic knowledge of how to reconstruct proofs. By analyzing experimental lessons with a grade 8 class (students aged 13-14), we found that these task components, and their interactions, contributed to developing students’ strategic knowledge. Using open problems with flow-chart proofs in a web-based proof learning support system enabled students to find alternative proofs to the same problem, and promoted the process of them expressing their strategic knowledge of how to reconstruct proofs.
