Jennifer,
Regarding avoiding jumping around, good preparation and planning does well if the instructor sticks to the plan. One idea to manage the time is to try to put the most important information first in the lesson. This takes preparation because the flow of information usually requires a certain order. Nonetheless, preparing for 75% of the class time with "need-to-know" material allows the remaining 25% of class for the "nice-to-know".
