My best teacher or mentor:

• Created an environment where I wanted to learn.

This is the best answer because it says that the most important thing is for the student to have all the resources he or she may need to learn. An environment that encourages and motivates learning is:

• more likely to be used;
• is more likely to engender learning; and
• is more likely to be re-visited, therefore ensuring upgraded skills.

And what are the features of a great learning environment?

• Provide content and feedback
• Fun and games
• Lots of feedback
