Who might benefit from Powerpoint: People who remember ideas after seeing them (in addition or instead of just hearing them) benefit from Powerpoint. Students who struggle to stay on-task or remember what is being done during class time, or who might need to step out of class temporarily to use the bathroom or another reason, might benefit from having Powerpoint slides there to anchor or update them (without the professor needing to pause and catch them up to speed, or asking a classmate). Students with hearing issues might benefit from having text to read if they cannot hear what is being said (though this just helps for what the teacher has said, not their fellow students). Students who are English Language Learners, or who are used to another accent or regional dialect of English, might benefit from being able to read the text if they cannot easily understand it from listening. Or, professors who themselves are English Language Learners or have an accent unfamiliar to their students can benefit from having their spoken words reinforced by visual text. Students who struggle with note-taking can benefit from having a powerpoint to refer to after class has finished. And students who were not in attendance
Who might struggle with Powerpoint: People who struggle to read or have vision issues won’t get as much use out of this tool, as it is primarily visual in nature. People with attention issues might find this tool creates overstimulation and find it hard to divide focus between what people are saying and doing in class and what is being projected in the slideshow at the same time. Professors with perfectionist tendencies, or without much experience teaching, can can waste precious hours making endless edits or searching for the perfect picture that don’t make meaningful changes to what students get out of the slideshow. (Is this last one from experience? You bet!)
