Abstract
Medical education is constantly evolving worldwide and facing various challenges. To cope with these, continuous and fruitful evaluation of an educational program is the need of the day. This study aims to know the purpose of evaluation, various theories related to program evaluation, and different models of curriculum and program evaluation. This will help educationists evaluate their programs fruitfully and effectively according to their needs and objectives. Different search engines including Medline's PubMed interface, Google Scholar, and Cochrane Review databases using keywords, curriculum evaluation, evaluation models, and evaluation strategies in education, were searched without any date restrictions, and 20 full-text articles were selected for review and data extraction. While reviewing the literature it was found that most of the modern educational program and curriculum evaluation models are based on the reductionist, system, and complexity theories of evaluation. The experimental/quasi-experimental model is based majorly on the linear approach and reductionism, but its drawback is that it is impractical for the whole curriculum and sometimes ethically unfavorable. Kirkpatrick's model, Philips' model, the CIPP model, and the logic model are based on the system and complexity theory and are more practical in medical education. Each of these models has its advantages and limitations. In this review, the authors discussed the important distinctive features of these evaluation theories and models and their applicability and usefulness in evaluating different programs and curricula.
