AB  - The rise of electronic assisted presentation programs such as PowerPoint in undergraduate large lecture biology classes has displaced more traditional hand-drawn lectures such as the blackboard or overhead projectors, referred here as “chalk-talk” approaches. But which method is more effective in a large lecture microbiology classroom is unclear. Here I present data from a large microbial genetics lecture course taken during a five-year span comparing PowerPoint to chalk-talk lecturing methods. The results indicate that the chalk-talk approach was preferred by the students and rated higher in all measured metrics including course enjoyment, learning of key concepts, and course outcomes.
