Teaching Histology Using Self-Directed Learning Modules (SDLMs) in a Blended Approach

Abstract
Introduction: New technologies like virtual microscopy have revolutionized histology education. However, first-year students often require additional assistance with virtual slides. Online self-directed learning modules (SDLMs) were developed to provide such support to learners by offering them short instructional videos that are uploaded to YouTube and the instructional website. The purpose of this study was to determine the effectiveness of SDLMs and to sample students' opinions about SDLMs. Method: -tests. Student opinions about SDLMs were collected using an anonymous survey. The survey results were analyzed by average scores and thematic analysis of the narrative responses. Results: Using SDLMs in a blended approach showed significant improvement in students' academic performance - irrespective of the method of assessment. There was a strong positive correlation with the performance when students were assessed using the virtual slide method. However, a standalone approach using SDLMs did not positively impact learning outcomes. Survey results indicated that most students perceived the videos as helpful for understanding the subject better and as quick review opportunities. Conclusion: The results support the use of SDLMs in a blended instructional approach and as an adjunct resource to conventional microscopy. This use of SDLMs was positively received by learners and significantly improved the learning outcome.
