The document discusses the four elements of instructional strategy according to Dick and Carey: 1) Content sequencing and clustering, which involves deciding the teaching sequence and content groupings; 2) Learning components, which should gain and hold learner attention; 3) Student groupings, which considers social interaction and balancing individual vs group learning; 4) Selection of media and delivery systems, which matches media to learning objectives and ensures media availability. Developing the instructional strategy before materials helps accomplish objectives.
