The Post-Lecture Classroom

An anonymous reader writes "The Atlantic reports on a study into reversing the typical lecture/homework educational method. The study had students watch lecture videos at home, then use class time to work on activities. After three years of trials, the researchers found both a student preference for the new method and a 5% increase in exam scores. 'In 2012, that flipped model looked like this: At home, before class, students watched brief lecture modules, which introduced them to the day's content. They also read a textbook — the same, introductory-level book as in 2011 — before they arrived. When they got to class, Mumper would begin by asking them "audience response" questions. He'd put a multiple-choice question about the previous night's lectures on a PowerPoint slide and ask all the students to respond via small, cheap clickers. He'd then look at their response, live, as they answered, and address any inconsistencies or incorrect beliefs revealed. Maybe 50 percent of the class got the wrong answer to one of these questions: This gave him an opportunity to lecture just enough so that students could understand what they got wrong. Then, the class would split up into pairs, and Mumper would ask them a question which required them to apply the previous night's content... The pairs would discuss an answer, then share their findings with the class. At the end of that section, Mumper would go over any points relevant to the question which he felt the class failed to bring up.'"

5%?

I don't know what the standard deviation of exam scores is, but a 5 percent improvement over 3 data points HARDLY seems statistically significant.

It should be noted...

It should be noted that studies have consistently shown that pretty much any change in methodology leads to higher marks the first time is tested, as students place extra effort on the face of an unknown teaching technique. The challenge is to produce gains that are lasting, once the students have gotten used to taking classes this way.

I'm currently three weeks into a Physics class that's modeled on this concept. Let me tell you what it's like.

In theory: Students review the lecture material on their own time. In class, the instructor presents some Physics problems on the topic. The students work through them together in teams and learn from each other, and the instructor reviews each team's work to help them get past sticking points.

In practice: I review the lecture material on my own time. My classmates do not. They show up largely unprepared, and when presented with a basic problem, simply stare at it until someone else explains the entire problem to them. Typically, that means that I end up teaching my classmates Physics, and then showing them how I solved each of the problems. I need to do that, because a significant part of my grade is based on the performance of my team - i.e., the average of individual quiz scores of the members of my team.

The instructor routinely harangues students to come to class prepared, and is assigning increasing amounts of busywork to be performed outside of class to ensure that work is being done.

So for me - a very reliable self-starter and independent studier - this class model means that in addition to learning all of the material on my own, I also have to (1) spend several hours in class teaching the material to my classmates, (2) have my grade dragged down by my team members' poor performance, and (3) have to complete additional work outside of class to prove that I'm keeping up. In other words, of the 10+ hours a week that this class is requiring, LESS THAN HALF is spent learning the material and honing skills; the rest (including the 4+ hours of class time) is simply wasted, thanks to this poorly implemented learning model.
