At this point in the term, many professors perceive a too great a sense
of routine displayed in their classroom, and are seeking energize their
teaching. But where do we start? Perhaps some research published several
years ago by D.G. Treichler*, which found that students learn:
- 10% of what they read;
- 20% of what they hear;
- 30% of what they see;
- 50% of what they both see and hear;
- 70% of what they discuss with people whose opinions they value;
- 80% of what they personally experience; and
- 90% of what they teach to other people.
The implication of these findings are compelling, especially for those
who rely too much on lecture as their primary tool of instruction:
- Lecture less;
- Use more audio-visual aids, including computer-generate graphics,
when lecture is necessary;
- Provide frequent opportunities for students to solve problems and
discuss issues in small groups, where they will feel less inhibited;
- Integrate personal reflections on course issues into your curriculum,
through journalizing assignments and essay questions on examinations;
- Provide opportunities for students to teach each other, by encouraging
the formation of study groups, and more presentations, especially the
less-threatening panel discussions, role playing, and debate formats.
Your integration of these approaches into your teaching will not only
insure better retention of the course material, but make your role more
interesting and rewarding.
