In backward design, instructional material is determined after establishing the learning outcomes, assessments, and activities for the course. This helps instructors focus on the perspective the learners and the end goal of the course. This method also helps instructors determine essential information versus extraneous information that may not contribute to the objective of the course.
Now, consider the kind of instructional materials that will best equip your learners to participate in activities, succeed in their assessments, and achieve the intended outcomes. Think about the learning experience you want your learners to gain in each module and in your course as a whole. Determine the most appropriate materials and method(s) for instructional delivery, which include but are not limited to: video, textbook readings, recorded demos, PowerPoint slides, articles, and graphics. Keep in mind that delivery of content should always be accessible, providing alternative modes of delivery: transcripts, descriptive text, speech-reader capability, searchable text, etc. See Accessibility Guide.
