Recently my mentor, Paul Martinelli, was talking about creating and delivering content for various audiences and in a variety of ways. As part of his lesson, he said, “Content dexterity is key. You need to be able to speak on your subject for 3 seconds, 3 minutes, 3 hours, or 3 days”. Having taught many 3-hour class sessions in more than 20 years of teaching experience, that time period certainly is comfortable for me, but what about the others?
As textbook authors, we often write the book around the expectation of class sessions. We envision the classroom audience, the common structure of classroom time where our book will be used, and the depth and breadth of coverage of concepts necessary to meet the curriculum standards of the course. We then have a tendency to structure chapters and units around those constraints.
But I question whether that approach is effective in our current educational environment. Below I offer some ways that you might want to consider building content dexterity into your next textbook.
