In your instructor delivery, which manner of speaking should be avoided?

The focus on avoiding mumbling in instructor delivery is essential because clear communication is fundamental to effective teaching. When an instructor mumbles, the audience may struggle to understand the material being presented, which can hinder learning and engagement. Clear articulation of words allows learners to grasp concepts accurately and follow along with the lesson. This also reflects the instructor's confidence and mastery of the subject matter, which can enhance students' trust in the material being taught. Ensuring ideas are communicated effectively, with appropriate volume and clarity, fosters a better learning environment where students can actively participate and absorb information.
