On the Different Ways That Mathematicians Use Diagrams in Proof Construction
Samkoff, Aron; Lai, Yvonne; Weber, Keith
Research in Mathematics Education, v14 n1 p49-67 2012
The processes by which individuals can construct proofs based on visual arguments are poorly understood. We investigated this issue by presenting eight mathematicians with a task that invited the construction of a diagram, and examined how they used this diagram to produce a formal proof. The main findings were that participants varied in the extent of their diagram usage, it was not trivial for participants to translate an intuitive argument into a formal proof, and participants' reasons for using diagrams included noticing mathematical properties, verifying logical deductions, representing ideas or assertions, and suggesting proof approaches.
