1) Capture the students’ attention. Since students are forced to be in the classroom, you cannot assume that all students are there to learn. You must make presentations interesting to all students (or as many as possible) in order to actually teach students the information.
2) Use a variety of techniques in your presentations. Not all students are visual learners. Some are auditory learners, while others have to learn by doing. A good presentation takes into account all different types of learners, using diagrams, pictures, sound clips, and a variety of other tools.
3) Do not expect students to be able to listen while doing other things. For example, do not give students a worksheet to fill out while you (or anyone else) is giving a presentation. Also, encourage students not to take notes while you are speaking. Have them only write down important talking points and things they did not know before.
