Ia menjelaskan mengapa pembelajar dewasa berbeda dengan pembelajar umumnya. Karena Knowles berasumsi bahwa :
Sedangkan perbedaan androgogy dan pedagogy dapat dilihat pada daftar berikut ini:
1. Demands of learning :
Andragogy: Learner must balance life responsibilities with the demands of learning.
Pedagogy: learner can devote more time to the demands of learning because responsibilities are minimal.
2. Role of instructor :
Androgogy : Learners are autonomous and self directed. Teachers guide the learners to their own knowledge rather than supplying them with facts.
Pedagogy : Learners rely on the instructor to direct the learning. Fact based lecturing is often the mode of knowledge transmission.
3. Life experiences :
Androgogy : Learners have a tremendous amount of life experiences. They need to connect the learning to their knowledge base. They must recognize the value of the learning.
Pedagogy : Learners are building a knowledge base and must be shown how their life experiences connect withthe present learning.
4. Purpose for learning :
Androgogy : Learners are goal oriented and know for whatpurpose they are learning new information
Pedagogy: Learners often see no reason for taking a particular course. They just know they have to learn the information.
5. Permanence of learning :
Androgogy : Learning is self-initiated and tends to last a long time.
Pedagogy: Learning is compulsory and tends to disappear shortly after instruction.
