Oral evaluation of subject area competency allows an instructor insight into the problem solving process students are applying to their coursework. Student were assigned to record themselves giving a brief narrated solution to one homework problem per textbook chapter. These narrated solutions were implemented into a core undergraduate course. Average exam scres and standard deviations were tracked for student grades (out of 100%) for the three course exams to minimize the effect of varied exam questions; these statistics were averaged before and after implementing the narrated solutions. While average exam scores experienced small changes, the standard deviation of the means decreased by 0.78 on Exam 1, 0.70 on Exam 2, and 0.60 on Exam 3, when compared to semesters of similar length and structure. The tighter spread of student exam scores after implementing narrated solutions demonstrates a deeper class cohesion of understanding, which leads to more positive student outcomes.
