In my own version of the calculus lab (I do about 10 per semester), some of the labs support lecture and some replace lecture altogether. I structure the activity so that students must do preliminary reading and exercises, then they have the hour in the lab with a partner and my help, and then there are followup questions. At least a few of these require more lab work; we have an open lab available to students for about 75 hours each week.
My (undocumented and unscientific) belief is: the students need to spend as much and usually more time on these assignments than they would for a typical one hour lecture, I have to spend at least twice as long evaluating and as much as five times as long prepping, and we all get more out of it.
