The main objective to change the participants knowledge, attitude or skills.
The basic requirement for acquiring or altering knowledge (concepts, ideas, facts etc.) is that information be presented clearly lo the learner. He / she should receive feedback on attempts to communicate an understanding of the new information.
Appropriate techniques for communicating information include interactive lecturette, (including two-way question/ answer); open discussion; symposia where members of the audience are given the full opportunity to question the speaker; television; films; tape recordings or readings which are analysed by the group of participants with the direction of the trainer.
Change in the actual ability to do something usually requires guided practice with feedback about the success or failure of the practice. Many people believe that group- relevant skills, such as keeping a discussion on the topic, can be learned through practice. It is possible to learn all about driving a car by reading a book, but the actual driving can only be learned by doing, by seeing the results, and doing it again.

If attitude change is desired, it is appropriate to utilize small, informal, open-¬ended discussion groups where the individual will not feel threatened. To the degree that these discussion groups are important or valuable to the participants, attitude changes are more likely to be lasting.
