Fostering learning is very simple. In addition to open-endedness there are some other qualities in my mind I decided to name as
|Communicate. Have a dialogue with your students, the most effective communication is reciprocal and includes negotiations of meaning.
| Acknowledge their competence, and help to add into it. Validate their knowledge and understanding.
| Feedback early and often. Provide feedback about the process (think of mapping the ground that lies ahead them, it is easier to steer clear when you know where the pitfalls are).
| Encourage and empower. Support their choices. Point out other possible directions (make sure not to choose for students).
And just like coffee, or life in general, also education is best when you enjoy it – not shoved down your throat.
