An interactive lecture is an easy way for instructors to intellectually engage and involve students as active participants in a lecture-based class of any size. Interactive lectures are classes in which the instructor breaks the lecture at least once per class to have students participate in an activity that lets them work directly with the material.
So what's wrong? In short, the common thread I see throughout all the failures is quite simply a lack of empathy. There is no authentic encounter with students, or what Martin Buber called "a genuine meeting." When we use all the right methods, and we still fail, it is most likely because we are encountering our students as objects and not as the rich and complex individuals that they are. When we do not bring our authentic selves to the classroom and open up to an authentic encounter with our students and the topic at hand we fail, regardless of the methods we choose.
