- In the past, a computer-based presentation in a classroom was rare and "cool." No longer! Today, students regularly view such presentations, so unless yours are absolutely stunning—a difficult feat—these are no longer special.
- With slides, students focus on reading or examining what’s projected. This results in students being distracted from and inattentive to what is being said.
- Writing and drawing on a board helps control the pace of presentation. Pauses can be worked in to give time for students to take notes or examine the board. This way less students miss what is being said.
