The present group learning system was designed to supplement existing teaching practices by providing remedial assistance with problem solving skills for the large number of students (-1400) in first year physics courses in the University of Sydney. Traditional lectures, whether live or televised, tend to concentrate on the exposition and extension of course material and devote little attention to the details of problem-solving procedures. The effective use of small group tutorials is usually severely limited by large student /staff ratios, and in normal problem-solving assignments, feedback is necessarily delayed, infrequent and lacking in detail.Programmed problem-solving sessions can, however, actively involve students in the learning process andcan give them immediate knowledge of their results.
