Evidential Based Classroom Evidence
Some would say that the most important term and concept in science is "evidence". There are several ways that teachers can present evidence to be analyzed by student's. Some of these presentation modes can save time and complete the create-test-use (CTU(T)) cycle. The assumption is that for students to understand the rules of the knowledge game they must repetitively see the full cycle of scientific concepts. They must see a concept created, tested, and then used with confidence. However, occasionally students must also see concepts tested and falsified (and then restricted, revised or replaced). Like all work in science, this requires evidence but the evidence does not always have to be collected by the student in a typical laboratory investigation. There are several evidential bases that can be used. Ideally, a full complement of evidential bases and at least one full cycle of create-test-use would accompany each unit of work in a course.
For a complete description of create-tests-use laboratory work see the CRYSTAL Alberta website.
