Adults learn for different reasons than children do – typically because they want to or have to, for personal and professional reasons. Here is a brief summary of Malcolm Knowles’s principles of adult learning, honed over 40 years, and bolstered by recent research into how the brain functions and how it learns. Consider the following principles of adult learning when planning meetings and interactive webinars.
A unique feature of a community of practice is its ability to ensure reciprocity. In this context, reciprocity means ‘when one teaches, two learn’. In a community of practice, all members are seen as both learners and teachers, regardless of their experience or role. This widens everyone’s openness to all ideas and increases opportunities for learning.

Being open to new ideas and being willing to learn from others is a key component in successful communities of practice. Cultivating this attitude means moving from a closed, ‘we have the answers’ attitude to a genuine openness to collaborating with others.
