This study examined knowledge gains about early intervention programs using a computer-based training with pediatric residents. Fourteen pediatric residents at the University of Maryland School of Medicine were pre-tested, provided with training, and post-tested. Given in a computer lab, the training was part of the residency education program. Results showed a statistically significant increase in test scores post- intervention. The training was more effective in teaching about early intervention law, philosophy, and recommendations for physician screenings than it was in teaching best practices for making referrals to the early intervention program. Findings were consistent with past studies on computer trainings in other medical topics. Limitations included small sample size and lack of a control group or follow-up assessment to measure maintenance and generalization of knowledge gained. Further investigation should look into the kinds of learning for which a computer is suitable versus the kinds that require more personal teacher-student relationships.
