The document discusses different approaches to instructional design including brain-based learning, scaffolding, and inquiry-based learning. Brain-based learning aims to enhance how students process information by providing instructional support. Scaffolding involves providing just enough support to address most student needs and gradually reducing support as skills develop. Inquiry-based learning shifts the focus from finding right answers to seeking resolutions to issues, and uses questions to promote critical thinking rather than just recall. It treats students as knowledge builders rather than just recipients of information.
