Classroom Discussion: Productive or Not?

The LDS Sunday School General President posted this short article at LDS.org (in the Church News section). Here is his observation about LDS classroom discussion:

[W]e hear of many inspired classroom discussions. Occasionally, however, we hear of discussions that are open and lively, but at the conclusion there has been little, if any, doctrinal focus or emphasis. In essence, there have been some therapeutic conversations or a sharing of experiences, but little connection to doctrine.
