Have you seen this…?...Students and Proof: Bounds and Functions. A DVD for Mathematicians

Using funding made available by the Maths, Stats & OR Network I have produced a DVD for mathematicians who want to understand more about the way their students think while trying to construct proofs. The DVD contains material from two research interviews , in each of which a student attempts to answer proof tasks about upper bounds of sets of real numbers and about functions and maxima. The video content is specially annotated so that half of the screen shows the student as they work on the problem and the other half is white and has subtitles appearing in blue at the bottom and a printed version of what students write on top…
