I am going to try digital blackboard presentations for a bit to see how that goes.
Kind of like this:
Information retention from PowerPoint and traditional lectures
"...use in university lectures has influenced investigations of PowerPoint’s effects on student performance (e.g., overall quiz/exam scores) in comparison to lectures based on overhead projectors, traditional lectures (e.g., “chalk-and-talk”)..."
"Students retained 15% less information delivered verbally by the lecturer during PowerPoint presentations, but they preferred PowerPoint presentations over traditional presentations."
Does a High Tech (Computerized, Animated, Powerpoint) Presentation Increase Retention of Material Compared to a Low Tech (Black on Clear Overheads) Presentation?
"The purpose was to determine if differences in (a) subjective evaluation; (b) short-term retention of material; and (c) long-term retention of material occurred with the use of static overheads versus computerized, animated PowerPoint for a presentation to medical students."
"There were no significant differences between the groups on any parameter. Conclusions: In this study, students rated both types of presentation equally and displayed no differences in short- or long-term retention of material."
