Outline of Final Research Achievements

Proving is an essential component in mathematical activities, but a difficult one for many students. We assume that one reason for this might be that unsuccessful arguments made during the process of planning a proof do not appear in the completed proof, and therefore students cannot see how those arguments influenced the proof. If students could reflect on such arguments, they would be able to learn about proving.
This study focused on Toulmin’s studies on argumentation, characterized processes of proving concerning its plausibility and probability, and examined students’ learning processes by designing, implementing, and analyzing eighth-grade geometry lessons. It constructed a learning process that consists of conjecturing statements, planning and constructing proofs of the statements, reflecting on the processes of planning proofs based on constructed proofs, finding new statements and considering the relationship between the initial and new statements based on the plans.
