Purpose
As more medical curricula move to prosection-based gross anatomy approaches, there is a need to incorporate active learning strategies into anatomy laboratories to maintain and hopefully improve meaningful engagement with course content. A novel, interactive prosection experience focused on active learning allows students to engage with their donor in a formative laboratory setting and reinforce anatomical concepts with maximum flexibility and automated feedback.

Methods
Fixed images (radiology, osteology, etc.) with hover-over structure identification were developed in Microsoft PowerPoint and exported to .html files using iSpring Suite. Guided prosection laboratory modules were developed to serve as interactive laboratory manuals, guiding students through organized identification of prosected donor structures, incorporating functional content and questions throughout. These resources were launched in a prosection-based gross anatomy course for first-year medical students. Students completed a survey evaluating the function and efficacy of the modules. Website engagement data was collected via Google Analytics.

Results
Out of 116 survey responses, 73% of students report using the laboratory modules 1-2 hours per week, 68% use the modules both with the prosected donor and as stand-alone study, and 69% believe their assessment scores reflect the time and effort they spent on modules. Students appreciated the accessibility of the modules, reinforcement of course content, engagement of the active-learning style, and complementary nature of the modules and prosected donor experience. Anatomy Interactives site usage drastically increases in the 1-2 days before an exam. Module page traffic increases on laboratory days, with a smaller increase the day prior to and day after lab sessions as well.

Conclusion
Anatomy Interactives and Prosection Laboratory Modules encouraged student engagement throughout the introductory gross anatomy course for medical students. Novel tools like these incorporate active learning into prosection-based laboratory settings and aid in the transition from dissection- to prosection-based approaches.
