<p>Strick11, actually a small class os more complicated to run. In a large lecture class the prof only needs to prepare a good syllabus and a set of good lecture notes. The unknown factors are few. A small class is more likely to have discussion and in fact most of the class is likely to revolve around discussion. It is not possble for the prof to totally prepare for such a class because discussion may take off on unsuspected tangents. The prof must think up appropriate questions on the fly. Because students are encouraged to participate, the prof must be able to reign in students who dominate the class while drawing out those more reticent. Questions may be posed for which the prof may not have a ready answer.</p>
<p>No, the small discussion class is much more difficult to instruct.</p>
