  11. 11. How can wesupport informeddecision making ?
  12. 12. Question #1What decisionslearners make inthe developmentof their owninvestigations?
  13. 13. Question #2How do learnerscome to makesuch decisions?
  14. 14. Question #3What aspects ofthe learningenvironmentsupport thesechoices?
  15. 15. MethodsYin’s (2003) comparative casestudiesContext: A one weekimplementation of KC with learnersbetween the ages of 9 to 13.Case selection: Three Choice Daygroups
  16. 16. Videos of Interviewed Field notes StoryKitall activities learners entries

  18. 18. Lisa & “ Togo ” Cakes
  19. 19. Denise , Lily , and Meg & Red Velvet Cakes
  20. 20. Choice Day Synopsis“Togo” cakes – Pancakes with syrup inthe middleEngineering tasks: Enough fluffinessand how to get the syrup in the middleof the syrup
  21. 21. Q1: What decisions were made?Decision #1: Chose to use baking powder asa leavener and determined the amount touse with an experiment.Decision #2: Chose to freeze different syrupsto as the way to insert the liquid into themiddle
  22. 22. Q2: How were the decisions made?Decision #1: Looked for heights of the foamgenerated from specific quantities of bakingpowder, water, and time in the microwave
  23. 23. Q2: How were the decisions made?Decision #2: She developed an experimentto test out whether honey, corn syrup ormaple syrup would freeze well enough to beinserted into the middle.
  24. 24. Q3: What aspects of KC helped? Facilitators Semi-structured experiments Whole group discussions Technology
  25. 25. Choice Day SynopsisRed velvet cake – Denise wanted to makethis because her aunt made this style ofcake.Denise initially did not think of this as ascience investigation; she just wanted tomake the cake.
  26. 26. Q1: What decisions were made?Decision #1: Comparison cake and aregular cake.Decision #2: The regular cake uses oneegg and baking soda + vinegar.The comparison cake uses two eggs andbaking powder.
  27. 27. Q2: How were the decisions made?Decision #1: The adult facilitators workedwith the girls to figure out what their goalswere for the cake.
  28. 28. Q2: How were the decisions made?Decision #2: The girls wanted a “cakey” and“moist” cake.
  29. 29. Q3: What aspects of KC helped? Facilitators Semi-structured experiments Whole group discussions Technology
  30. 30. Learners and Choice Science is not just aboutthe content knowledge and the social practices. Learners may need a sense that making informed decisions matter. We attempted to use the four aspects of KC to explore the notion thatlearners can make viable decisions.
  31. 31. # 1Early Decision Making Matters
  32. 32. Mobile TechnologiesSemi Structured ActivitiesChoice DayWhole Group Discussions Facilitation
  33. 33. # 2 &Guidance Organization Matters
  34. 34. Alignment Tension in decisions
  35. 35. # 3Reflection Matters
  36. 36. Slow Down Reflect
