Hi Marianna: My approach to instructional media attempts to use lots of variety, mixing up the sequencing so students stay attentive, getting the students involved in the instructional process as much as possible, and having integrating student group study along with media. The combined power of multiple ideas along with good resources with students participating seems to improve the learning process. Some things have to be lectured, but involvement and being engaged with participation is just as effective if structured correctly. Regards, Barry
