Ben Witherington III, Is There a Doctor in the House? An Insider’s Story and Advice on Becoming a Bible Scholar (Grand Rapids: Zondervan, 2011), 113:
[excerpt from ch. 9: “Honing Your Rhetoric: The Ability to Lecture and Teach”]
Learning Is Not Enough for Good Lecturing
Sadly, some Christian teachers ought not to be teachers, but because there are so few pure research professors in biblical studies or in any sort of Christian studies, these folks become teachers by default. Some of them can’t lecture their way out of a paper bag. I had a teacher like this in college. The running joke was that the difference between this teacher and the textbook was that the textbook didn’t mumble or stutter. As cruel as that joke may seem, it was an accurate assessment of this poor man’s attempt to teach. He couldn’t explain anything. He just kept quoting the textbook.
Tragically, too few Bible teachers or scholars have had any training in pedagogy, much less in Christian education. Furthermore, they have never even been taught the rudiments of good communication.
