Using the evaluating instructional materials.

To ensure effective use of instructional material,book authors on instructional media advise us to abide by the acronym PPPF which means Prepare yourself-you know your lesson objective and what you expect from the class after the session and why have selected such particular instructional material. Prepare your student-seat class expectations and learning goals.Prepare the material-under the best possible conditions.Follow up-remember that you use instructional material to achieve an objective,not to kill time nor to give yourself a break,neither to merely entertain the class.
