HYPOTHETICAL LEARNING TRAJECTORY ON INFORMAL HYPOTHESIS TESTING IN A PROBABILITY CONTEXT

A design experiment where students in Grade 5 (11–12 years old) play the Color Run game constitutes context for investigating how can be introduced to informal hypothesis testing. The result outlines a three-step hypothetical learning trajectory on In first step, came favor sample space reasoning over idiosyncratic when was changed between color runs. second and third steps, used degrees of variation distribution mode across samples infer whether an unknown uniform. Students’ disclosed logic: larger variation, greater reason rejecting uniform space.
