An initial evaluation of learning units to facilitate problem solving and self-directed study (portable patient problem pack)

This paper describes the initial evaluation of the portable patient problem pack, a learning unit designed to facilitate the development of problem-solving skills and stimulate self study. A cross-over design using two neurological patient problems, each presented in two formats (simulated patient and P4), was used with a sample of twenty-nine volunteer nursing and medical students. The results indicate that the P4 appears to be feasible and effective in stimulating problem solving and self-directed study. The suggested concurrent validity, low cost of production, and implementation make it a potentially potent tool for evaluation.
