Using Maple and the Web to grade mathematics tests

We present AIM, a web-based system designed to administer graded tests with mathematical content. Its main features are: use of Maple as the engine and implementation language; several methods of giving partial credit; various feedback mechanisms; randomisation of quizzes and questions; versatility in question and quiz design; extensive grade reporting and monitoring capabilities; ability to collect surveys; web interface for both teacher and student. AIM can be used to administer graded tests, homeworks or ungraded self-assessment exercises. A case study using vector calculus was conducted and more courses are being planned for September 2000, including linear algebra, ODEs and precalculus. Preparation is also under way to use AIM to mark a part of the final exam for linear algebra in February 2001.
