5th European Workshop on Mathematical & Scientific e-Contents

Christopher J. Sangwin, University of Birmingham. United Kingdom

Is a Senior Lecturer in the School of Mathematics at the University of Birmingham in the United Kingdom. Since 2000 he has been seconded half time to the UK Higher Education Academy "Maths Stats and OR Network" to promote learning and teaching of university mathematics. In 2006 he was awarded a National Teaching Fellowship. His learning and teaching interests include (i) automatic assessment of mathematics using computer algebra, and (ii) problem solving using Moore method and similar student-centred approaches. Chris Sangwin is the author of a number of books, including "How Round is Your Circle", which is an attempt to promote the links between mathematics and engineering using physical models.

Learning from learning technology

This talk will examine computer aided assessment (CAA) systems for mathematics. By having a computer algebra system automatically mark answers, I will articulate some issues which arise for teachers.

What does CAA teach us about mathematics?
What does CAA teach us about assessment?
What does CAA teach us about students, and how they learn?

A fundamental part of each CAA system is a data structure which represents the "questions", together with an interaction model through which students use them. The aim of this talk is to explain the design decisions made in developing the STACK CAA system and to contrast this with other mathematical CAA systems.
