This article describes a curricular change project designed to improve instruction in biochemistry. After years of unsatisfactory outcomes from a dental hygiene biochemistry course, a decision was made to change the traditional lecture-based course to an online format. Using online technology and principles of educational pedagogy, a course was developed that fosters application of biomaterials principles to dental hygiene practice and provides a bridge between prerequisite chemistry coursework and biochemistry in a health professions program. Members of the dental hygiene graduating Classes of 2007 and 2008 participated in the revised course. The outcome measures used to assess the effectiveness of the revised course were student end-of-semester course evaluations, graduating senior survey results, student course performance, and National Board examination performance. While the results are based on only two classes, the positive outcomes suggest that the revision was a worthwhile endeavor. The use of technology in teaching holds the potential for solving many of the curriculum and instruction issues currently under discussion: overcrowding of the curriculum, lack of active learning methods, and basic sciences taught in isolation from the rest of the curriculum. It is hoped that the results of this change will be helpful to other faculty members seeking curricular change and innovation.
