PowerPoint (PPT) is a handy tool for instructors to present their lectures in both face-to-face and online courses. But the effective use of PPT varies from one mode of teaching to the other. Presenting a PPT manually in a face-to-face classroom is completely different from using it as a lecture slide in a time-based, video lecture. The screen time per slide and textual and figurative content per slide vary in the different modalities, and therefore the instructor should be mindful of the content and the time allotted per slide in online lectures.
In addition, PPT slides used in the online classroom should be fully accessible for mobile devices and should be mindful of the accessibility guidelines for color and information density.
