I recently started letting my high school science classes know what we would be doing each day of the present week. I type up a Monday through Friday list and briefly include what's on tap for each day. Experiments, quizzes, test, when homework is due are the kinds of things I include. This way they know what to expect and are more readily prepared for each day's activities. Several of my students have already told me it help them to see the 'big picture.' I post it on Monday morning now and hope to start posting it on the Friday before if I ever get caught up!
