different learning styles because it adds a visual element to your oral presentation. This is especially important because today’s students seem to be more visual than other generations.
• It helps reinforce the key information in your presentation and keeps student interest focused on the front of the room.
• It allows you to give students clear prompts for their assignments, especially in-class assignments. They can always look up to refocus their attention to the assigned task.
• Visual Aids can be used over and over again and can be electronically moved directly to a web site so that students can look at it again after class and as many times as they want.
• It serves as Ockham’s razor by helping you structure your thoughts.
