The Model-Observe-Reflect-Explain (MORE) Thinking Frame is an adaptation of the POE task intended to get at the goals of the course by providing students with a framework to guide their thinking. The MORE Thinking Frame differs from the POE task in several ways; (1) students begin a laboratory module by representing their initial ideas about the experimental system as a whole (their initial model) which requires students to reflect on their ideas about various aspects of the chemical systems rather than on an isolated experimental outcome, (2) it includes an explicit reflection component, (3) it includes the idea of model refinement therefore after each experiment in a module, students are explicitly prompted to reflect upon the implications of their observations for their model and revise their ideas accordingly, and (4) it uses metacognitive strategies such as connecting macroscopic observations with atomic- and molecular-level explanations.
