Puzzling data regarding lecturing teachers
Many of you know I am working on a new book on What Makes Groups Grow. I am puzzling just now over the data regarding teachers to lecture. Here is the puzzle:
- Teachers who use all lecture were the second mostly likely group to be growing
- Teachers who use all lecture were also the most likely group to be declining (by a wide margin)
I have my own theories as to why this is true. What do you make of it? How could the lecturing group be both likely to grow and likely to decline?
