Article - Why Long Lectures Are Ineffective

"Middendorf and Kalish also cited a study from 1985 which tested students on their recall of facts contained in a 20-minute presentation. While you might expect that recall of the final section of the presentation would be greatest— the part heard most recently — in fact the result was strikingly opposite. Students remembered far more of what they’d heard at the very beginning of the lecture. By the 15-minute mark, they’d mostly zoned out. Yet these findings — which were quite dramatic, consistent and conclusive, and have never yet been refuted — went largely unapplied in the real world."
Have you ever wondered why TV shows have commercial breaks every 5-10 minutes?  The obvious answer is for ad revenue.  The subtle answer is that people struggle to concentrate for beyond 15 minutes.  It's been proven.  Even during movies there are "breaks."  Scenes transition and something new is on the screen for viewers to decipher and learn from.

So when creating a Venn Diagram with "Movies/TV Shows" in one circle and "Classroom" in the other, it brought to my attention where similarities can be.  The article states 15 minutes.  I think it is shorter than that!  TV shows use that 5-10 minutes to hook you ... and then re-energize the brain with an advertisement.  Interesting ...

TRANSITIONS are the key to keeping students engaged in the classroom.  After the 5-10-15 minutes, how will you re-energize the brain of the student?
