(From Active Learning: Cooperation in the College Classroom by D. W. Johnson, R. T. Johnson, and K. Smith, Interaction Book Company, 1991, p. 5:1-5:9)

ADVANTAGES

  • can communicate large amount of material efficiently can be used to supplement or elaborate curriculum good if material has to be organized or presented in a particular way
  • can provide introduction to unfamiliar area
  • very efficient for expert-to-expert transmission
  • can be used to present material not available elsewhere or hard to discover because of originality, complexity, or difficulty
  • can be used to arouse interest in the subject
  • is effective if lectures are skillfully delivered, with clear, enthusiastic, modulated voice, good eye contact, and appropriate gestures
  • good mainly for auditory learners

PROBLEMS

  • student attention wanders periodically and decays with time, starting at about 10 minutes into the lecture
  • tends to promote lower-level learning of factual information
  • makes unwarranted assumption that all students need same information, presented orally at the same pace, impersonally and without dialogue with the presenter; have high memory capacity, have same prior knowledge, good note-taking strategies and skills, and are not susceptible to information-processing overload
  • students tend not to like it
  • entertaining and clear lectures can mislead listener about the complexity of material being presented.

ENEMIES OF THE LECTURE

  • preoccupation with outside affairs
  • emotional moods of listener
  • disinterest in material failure to understand
  • feelings of isolation and alienation from others

The list of advantages should be used to decide when to use the lecture as a teaching mode. If you feel that the content would benefit from giving lecture, the next stage is to take steps to combat the problems and enemies of the lecture.
