Three links, all of them fascinating:
Harvard's Eric Mazur, writing in Science (probably behind a paywall): Farewell, Lectures? Here's his highly quote-worthy problem statement:
... [T]he lecture method [is] a process whereby the lecture notes of the instructor get transferred to the notebooks of the students without passing through the brains of either.
And here is his solution (he has a lot more about it at his website):
Since this agonizing discovery, I have begun to turn this traditional information-transfer model of education upside down. The responsibility for gathering information now rests squarely on the shoulders of the students. They must read material before coming to class, so that class time can be devoted to discussions, peer interactions, and time to assimilate and think (4). Instead of teaching by telling, I am teaching by questioning.
I now structure my time during class around short, conceptual multiple-choice questions. I alternate brief presentations with these questions, shifting the focus between instructor and students. The questions address student difficulties in grasping a particular topic and promote thinking about challenging concepts. After posing the question, I give the students 1 to 2 minutes to think, after which each must commit to an individual answer. They do this by submitting their answers using handheld devices called “clickers” (see the figure). Because of the popularity of these devices, questions posed this way are now often referred to as “clicker questions.” The devices transmit the answers to my computer, which displays the distribution of answers. If between 35% and 70% of the students answer the question correctly, I ask them to discuss their answers and encourage them to find someone in the class with a different answer. Together with teaching assistants, I circulate among the students to promote productive discussions and guide their thinking. After several minutes of peer discussion, I ask them to answer the same question again. I then explain the correct answer and, depending on the student answers, may pose another related question or move on to a different topic.
Here's Sara Rimer's report on MIT implementation of a teaching methodology called TEAL -- Technology Enhanced Active Learning.
Finally, Dan and Chuck Heath, autors of Made to Stick are offering a bunch of short articles on the book's website. One of them is titled Teaching that Sticks (requires registration, though).
