I am an educational consultant and writer, and the most powerful learning experiences I have are when the folks I am consulting with/learning with have chosen to be part of the group, agree on the nature of the problem, and there is a high degree of trust among group members. I’m working now in a troubled middle school that won’t make AYP this year and might be closed due to underperformance. Many of the teachers and all the school leaders got together at the beginning of the year, though, and decided they would work on problems of instruction as a way to deal with their underperformance. Because everyone agreed this would be fruitful, and people have developed a lot of trust with each other about discussing hard things, we are really seeing improvement every day, even in test scores! But all three conditions: trust, agreement on the problem, and choosing to participate are ingredients of making this a powerful learning environment. Thanks for asking!
