Supporting KB teachers’ practice &
                 reflections
• 1st layer: Promoting open exploration and sharing of ideas
              • Are students participating in the online discourse?
              • Are there students who made zero contribution?

• 2nd layer: Progressive inquiry orientation
              •   Do ideas progress in the online discourse?
              •   Can students raise questions that stimulate idea improvement?
              •   What are the key content themes of the discussion threads?
              •   Which notes have potential for further development?
              •   Which aspect of the discussion can be further improved?

• 3rd layer: Inquiry or KB as a “habit of mind”?
              • Is there any advancement in my students over 1 or 2 years of KB
                activities, in terms of question framing, evaluating and summarizing
                ideas, as reflected from their contributions to the online discourse?
