As the students work through the data set, they are to examine each exemplar and develop hypotheses about the concept. They need to ask themselves what attributes the positive exemplars have in common. It is those attributes that define the concept. Students identify additional unlabeled examples as yes or no. Teacher confirms htpotheses, names concept, and restates definitions according to essential attributes.
Students generate examples.
Sometimes students are asked to record the progression of their thinking. I do not have a class to proceed with this at this time. Perhaps in the future. As the lesson progresses, we need to get information about whether the students are formulating and testing ideas. Students describe thoughts.
