Dissection has long been the primary method to gain greater insight into the structures and functions of the human body. It requires careful step-by-step analysis, retrieval of stored information, and spatial navigation to successfully explore our inner makings. Many facilities and campuses nationwide are not equipped for cadavers, and in particular, online laboratory settings are often devoid of hands-on dissection altogether. Anatomy 4D is an augmented reality (AR) mobile application that allows for human body exploration through enhanced dissection. Its application in laboratory settings may be a viable means of resolving hands-on dissection limitations. To investigate this idea, college anatomy students utilized the AR mobile application to dissect the heart organ in an action research study. Students performed activities individually, by creating personalized deliverables to share, and collaboratively, by contemplating connections through discussion. In better determining the impact of AR dissection in enhancing identification of human body structures among learners, pre and post assessments were conducted. Overall results indicated AR utilization for human organ exploration was positive with a marked increase of recognition after lesson activities and numerous indications of personal satisfaction from the use of mobile learning technology, constructivist design, and peer collaboration
