Abstract
We expect mathematical proofs to explain why the propositions in question are true or why certain mathematical phenomena occur in certain situations. In this paper, I reexamine explanationbuilding processes by taking them as problemsolvers’ understanding processes and by referring to research that has analyzed the relationships between explorations, understandings, and explanations in mathematical problemsolving. I discuss some interactive features among these components during problemsolving processes by introducing some examples and referring to that research. I then use those features to offer an elaborated conception of explanationbuilding processes that takes into consideration local explanations, full explanations, and the direct and indirect relationships between local and full explanations.
