The case study employs a qualitative method and examines two oral presentations at the university. Classroom observation was chosen as the appropriate tool to observe participants’ presentations, based on specific criteria. The results indicate that using Mayer’s multimedia principles in oral presentations provides a framework for designing effective multimedia presentations. This approach improves students’ oral presentation skills and performance, reduces their speaking anxiety, and facilitates well-structured delivery. Consequently, it enhances self confidenceandaudience comprehension. Keywords:First year students,Multimedia Principles, Observation, OralPresentations, QualitativeenThesis
