One of the key characteristics of inquiry learning is that students have to find out something themselves, an investigation is always the backbone of an inquiry process. As part of the student’s initiation and guidance, it may be a good idea to include a much guided, structured, step-by-step, exercise, but inquiry also means that student-led investigations are present. Therefore, an ILS should not be a mere sequence of step-by-step instructions for the student to follow like a recipe cookbook. There must be an inquiry aspect where the student searches for and tries various possible solutions. It is ok if the student initially fails and repeats a process. So, instead of telling a student which values to fill in for each variable, students should find out themselves what are the interesting values to use; of course, you can give them predefined experiment to follow (and you can define those experiments in the Experiment Design Tool), but there should be freedom for students as well.
