A Choice Option between Proofs in Linear Algebra
Rensaa, Ragnhild Johanne
International Journal of Mathematical Education in Science and Technology, v38 n6 p729-738 Sep 2007
At their final exam in linear algebra students at the author's university were given the possibility to choose between two types of proofs to be done. They could either prove two short statements by themselves or they could explain four steps in a given proof. This paper reports on investigations of students' responses to the choice option compared to the final grade of their exam: the relation between choice and grade, students' thoughts about why they preferred one proof to the other, and their opinions on having to choose. The analysis is based on the students' solutions and answers in questionnaires distributed immediately after the exam. The paper concludes that the students' opinions do not imply that there is a "best way" of giving a proof, but a choice option is preferred by almost all students regardless of final grade. It is thus asserted that the choice-option-project should continue. (Contains 2 figures.)
