PowerPoint overuse will be the death of student employability

Good points! The tools we use have an insidious effect on how we think and what we think. There is an effect on academics thinking in terms of their topic in terms of what can be placed on a powerpoint slide. Pity the lecturer with complicated equations or a long argument. It has also had an effect on campuses. There is a tacit assumption across campuses that a lecture hall now means a room with a projector set-up for IT Pity the poor academic who dares ask a room with large board space. if such a room is provided, the board has often suffered from neglect and is barely usable or so small that one is having to remove material before half of the class has finished writing it. Intentional or not, it ha the effect of herding everyone back towards online slides.

I'm notorious for my slides... they are primarily visual and serve as a prompt to me about what I want to say next. I back them up with links to materials that students can use to launch their independent study of whatever I have been talking about.

For decades, instructors have distributed written class/lecture notes to promote student attention. We have used slides and then online notes, visuals, quotations for years. This just doesn't make sense and is not supported with any evidence.
