There is not enough time in class to use collaborative learning activities

All the team work activities carried out effectively in class do not require much time.

Richard Felder, chemical engineering professor at the State University of North Carolina, suggests that some of the questions raised during the explanation in class should be assigned to small groups and then they should be given 30 seconds to get the answers (Felder and Brent, 1994). For example, instead of presenting all the material of the class in an explanation, the teachers can give the students some handouts with explanations and diagrams (Felder and Brent, 1994) leaving some blank spaces to fill them out during the class or afterwards. This way, the teachers can use the time that they used to use to write on the board, in other learning activities.
