Peripheral Brain Access in Small Group Discussion in Anatomy

The pandemic has forced medical education to adopt online and hybrid set-ups, and this has greatly changed the way human anatomy is taught. Course-required knowledge can be accessed using raw references like original publications, collected reviews such as those found in books, as well as in shorter versions like summaries, and in online or electronic applications or software. With readily accessible online physical materials and human resources in anatomy, the value of learning by seeking out verifiable information to answer a real time query may change the current method of teaching and assessment of outcome-based learning in a heavy-recall subject such as human anatomy. For the student, sources of information or instruction are termed the "peripheral brain". The objective of this study is to describe the medical students' method in accessing medical information during a hybrid small group discussion.

In a modified hybrid laboratory set-up, a class of 200 students were divided into 18 groups, with two students in each group acting as laboratory dissector, who will broadcast their in-person classroom activities to the group members via zoom. The groups rotated in nine specimen stations consisting of soft-embalmed cadavers, plastinated specimen, models, bones, and VH dissector™ virtual dissector. Students were allowed to use any type of resources to accomplish the following tasks: 1) look for listed structures, 2) identify landmarks, and 3) describe functions. A Google sheet survey was administered a month after the activity on the following domains: search strategy, targeted references, and verifiability of information.

There were 110 students with age range of 19-27 years old, who participated in the study. Their most accessed reference is still personally prepared notes, followed by electronic books. When using ebooks, the first thing students reported exploring is the table of contents, followed by the search button. If doing online search, the key word used is the structure or function of interest. In group dynamics, students prefer to divide the work and assign tasks to each member, instead of collectively and simultaneously discussing a topic. For them, the most important characteristic of a reliable peripheral brain is that it is the recommended reference, followed by how current the reference is, i.e., published in the last 3 to 5 years. Interestingly, for most students, the information must be acquired in 5 minutes, which is contrary to the preferred mode of reference.Artificial intelligence may enhance SGDs according to most of the students. In accessing peripheral brain, Google is perceived as the quickest, books are most reliable, and Pubmed is the most up-to-date. Most of the students preferred pre-assigned questions or tasks during SGDs, with equal distribution of work. Giving and receiving remote instructions is not a problem. Dealing with a difficult group member is important, but is not a problem in hybrid discussion.

The survey results provide valuable insight on learning strategies used by the current generation of medical students, who have started medical school during the pandemic and are used to online teaching-learning modes of instruction. These findings can be exploited in designing course activities. The concept of peripheral brain in small group discussions can be formally introduced to students learning anatomy to utilize modern technology in enhancing knowledge.
