Since my objective is for students to take responsibility for key decisions along the path of ongoing science investigations, I have developed a comparative framework that allows us to see the locus of key decisions as this process unfolds. For each model of inquiry, I present a list indicating the necessary decisions, and who makes them, the student or the teacher. In the open-ended inquiry model, almost all of the decisions are made by students. However, as will be seen, most students failed to move past the exploration phase, and thus did not actually make the question definition and experiment design decisions sought after.
