11. CMEF 2014 EARLY EFFORTS just do it teaching with problem solving TASKS 2005 2006 some were able to do it they needed a lot of help they loved it they don’t know how to work together they got it quickly and didn't want to do any more they gave up early FILTERED THROUGH EXISTING NORMS! assessing problem solving

21. CMEF 2014 DATA SOURCES TYPE I: qualitative written reports interviews field notes TYPE II: quantitative(ish) comparators - five different treatments per class 5 classes time measurements criterion measurements (0, 1, 2, 3)

22. CMEF 2014 QUALITATIVE MEASURES This was so great [..] it was so good I felt like I shouldn't be doing it. I will never go back to just having students work in their desks. How do I get more whiteboards? The principal came into my class … now I'm doing a session for the whole staff on Monday. My grade-partner is even starting to do it. The kids love it. Especially the windows. I had one girl come up and ask when it will be her turn on the windows.

27. CMEF 2014 VISIBLY RANDOM GROUPS

28. CMEF 2014 EMPIRICAL RESULTS students become agreeable to work in any group they are placed in there is an elimination of social barriers within the classroom mobility of knowledge between students increases reliance on the teacher for answers decreases reliance on co-constructed intra- and inter- group answers increases engagement in classroom tasks increase students become more enthusiastic about mathematics class Liljedahl, P.

31. CMEF 2014 TOGETHER I've never seen my students work like that they worked the whole class they want more how do I keep this up AND work on the curriculum? how do I assess this? where do I get more problems? I don't know how to give hints?
