Hi Betty: Sometimes too much or too little content is planned. This is especially true for new classes and/or new teachers. Course content is based on Course Objectives (CO's) and Student Learning Outcomes (SLO's). From there, the daily or weekly objective are derived. This is where the nitty-gritty of planning out lesson planning occurs. Smetimes, the best one can do is guesstimate how much time will be needed. A helpful technique is to have a good back up plan to introduce should extra time be avilable near the end of a class. Regards, Barry
