It is through the actual process of writing our thoughts and working them over that we really come to understand an issue. Written thought also allows us to later review and reflect on our understanding. We also better understand material by bouncing our thoughts off others. We need reinforcement that our understanding is the same as others. When it comes to attitudinal changes it is especially useful to bounce our thinking off other learners in addition to the faculty member who will have biases about course content.
Learners can learn from each other.
Learners who have worked for several years come to classes with a wealth of experience from which rich content can be presented to other learners. Generally online classes promote participation in discussions. The overall result is that slow thinkers and shy individuals are more likely to contribute than in a traditional classroom. Creating a friendly, social environment is also essential for promoting learning. Interpersonal interactivity motivates students.
