Foremost, for use in the classroom, PowerPoint can be used in many ways; for subjects where there is a definite correct or incorrect answer, a question can be posted on one slide and the answer on the next and this can be used for whole class testing. Higher up in the academic ladder with higher education and universities, notes can be typed up and projected onto a board, to make lessons easier for a teacher as they can be repeated time and time again without having to be written by hand on the board each time. Another advantage of doing teaching this way is that time can be spent discussing points on the board instead of time wasted writing the notes. These slide shows can then be either emailed, posted online on slide show sharing sites or printed so that students can catch up if any work was missed, or to ensure that their notes taken are comprehensive and to assist with revision.
