Knowles' principles of andragogy focus on involving adult learners in the learning process. The six key principles are that adult learners need to learn, want a respectful environment where their perspectives are valued, see the goals as their own, help plan the learning, actively participate, and apply their own experiences to the learning. Andragogical teaching contrasts with pedagogy in that it recognizes adults' self-directedness, wealth of life experiences, readiness to learn based on social roles, and desire to immediately apply learning to real-world problems. Andragogical design is therefore more collaborative, experience-based, and aimed at mutual negotiation of objectives and evaluation between learner and teacher.
