    the question [Question in the Focus step]. 34. Find all the unknown forces on the bar. [MK Sp Sp = Support
    writes this as Equation 2 on the Solution Sheet.] G MK frequently talks aloud as she writes. These are grounds because they come from the

  4. MK. OK...that sound good? Ck problem statement. Ck = Consensus Checking.
    Here Ck serves as a summary statement, could also be coded

  5. RM. Uh, huh. Sp as Sm.

  6. MK. Just so agreeable. En Encouragement is a form of light-hearted support.
