Session 15. Preparation for pedal/treadle presentations* *

Total time:

1 hour
* * This session should be scheduled a. the end of the day so that the participants are able to finish the work during the evening hours.


* To plan and design a presentation of a pedal-powered device
* To identify and use techniques for communicating complex technical concepts to informally educated people


Fuglesang, Applied Communication in Developing Countries, pp. 43-52


Newsprint and felt-tip pens

Trainer Notes

Copies of the resource material should be prepared for distribution during the session.

Remember to schedule this session at the end of the day so that participants are able to finish the work during the evening.


Step 1. (5 minutes)
Present the session objectives and outline the activities.

Step 2. (10 minutes)
Distribute a copy of Fuglesand to each participant and have them read it.

Step 3. (15 minutes)
Have the participants brainstorm and discuss a list of ways to present their devices to informally educated people.

Trainer Notes

Write the list on newsprint. It should include some of the following nonformal education techniques: skits, puppets, songs, pictures, games, diagrams, slide shows, models, etc.

Encourage the participants to describe how these techniques could be used to explain a complex technical concept.

Step 4. (10 minutes)
Have the participants identify which techniques would be most appropriate for their presentations.

Step 5. (20 minutes)
Have the participants form their construction groups and develop a presentation of their pedal/treadle devices.

Trainer Notes

* Explain that each group should develop a twenty-minute presentation and that it should be designed to be understood by people with little or no formal education.

* Point out that informally-educated people may have difficulty understanding the mathematics of pedal/treadle concepts but if they are familiar with bicycles, they will probably understand the principles of leverage, wheels, fly wheels, momentum, inertia, rhythm, etc.

* Explain that they should continue to plan and practice their presentations tonight and that they should be prepared to give them tomorrow.
