There is a method to this madness. First of all, humor is an often underused and unexploited variable in creating a positive classroom atmosphere. Secondly, the type of humor used in the error correction lecture is designed to create strong, often exaggerated, images that have the potential to touch the students on affective or emotional levels. In short, the humor used in the lecture is a vehicle to take the material being learned into deeper levels of cognitive awareness, that is, into long-term or even permanent memory. Not every error on the list needs to be presented comically, but humor is an effective teaching tool where applicable.
Most errors do lend themselves to a variety of possible interpretations.
Any teacher should be able to come up with a few humorous explanations within a single list of errors. When using humor, there is one point the teacher should keep in mind. It is essential that these interpretations not turn into any kind of condescending or derogatory comment. Errors should always be seen as learning tools. The message to the students should be that errors are a natural part of learning and everyone makes them.
