I'm teaching math in first years of university (matrix algebra, differential analysis, etc.) since maybe 5 years, and I usually give written (paper) exams to the students.
I'm looking for ideas to change a little bit my practice: I would like to do more exams, i.e. more tests during the semester to test the continuous work of the students, but without doubling or multiplying by 3 the exam-marking job.
Have you seen good examples of math exams using a computer, or multiple choice questions? for example for a basic matrix algebra course (matrix operations, rank, linear systems)
