Hi Robby: Choosing media is extremly important, and time and effort needs to be allocated for good planning. Mixing media choices helps keep the students attentions, provides variety, allows students to use different parts of their brain to learn, and it's just more interesting. A very important consideration is engaging or involving students (discussions, demonstrations, presentations, anything that directs them to learn on their own with the teacher simply facilitating). They'll retain information better and ultimately perform better as students and workers. Regards, Barry
