To support my learning I ask you to comment as follows:
1. Something positive - something you like about what I have shared.
2. Thoughtful - A sentence to let us know you actually read/watched or listened to what I had to say
3. Something thoughtful - how have you connected with my learning? Give me some ideas for next time or ask me a question.
