REORDERING HISTOLOGY TO ENHANCE ENGAGEMENTIn redesigning the preclinical curriculum and shifting from a discipline-based approach to an organ system-based approach, faculty at the University of Arizona College of Medicine in Tucson took the opportunity to restructure the sequence of introductory histology content to make it more engaging and relevant. As context, motivation, and problem solving are important factors contributing to learning (Koens et al., 2005;Norman, 2009), we sought to improve all three aspects in presenting the introductory histology material on tissue types.
TRADITIONAL HISTOLOGY COURSE SEQUENCEIn the medical curriculum before 2006, the sequence of histology content was that followed by many textbooks: basic cell biology, then tissue types, then organ systems. Despite having the same instructors teaching the basic cell biology and tissue types content as taught organs systems, we consistently had better student evaluations for the latter material than for the former. In addition, it was apparent from student comments that they did not have a clear understanding of the relevance of the tissue type material. We considered that this might be at least in part, because the justification for this material was essentially ''learn this now you'll need it later'' rather than having inherent and obvious relevance.
HISTOLOGY REORDEREDIn 2006, we undertook a major redesign of our preclinical curriculum and adopted an organ system-based approach (Fig. 1), which begins with a 9-week Foundations Block in which the introductory material of the major disciplines, including histology, is presented. The introductory histology content occurs mainly in the first week of this block (Fig. 2), and is organized as follows:
