Dr. Richard, You describe a very interactive system which sounds wonderful. Another meaning is the required Student Learning Objectives (SLO's) that are established by the institution and or program that define what outcomes must be completed in order for the student to pass muster. In this meaning, I look at the daily learning objective (DLO's) as "the how" of a topic, and SLO's as "the what" of a topic. What is it that is to be learned (see SLO's). How are we going to reach attaining the SLO's? (see the DLO's). Barry Westling
