The document summarizes the Dick and Carey Systems Approach Model for designing instruction. It consists of several iterative components including identifying instructional goals, conducting instructional analysis, analyzing learners and contexts, writing performance objectives, developing assessment instruments, developing an instructional strategy, developing and selecting instructional materials, conducting formative evaluation of instruction, revising instruction, and conducting summative evaluation. The model incorporates concepts from behaviorism, cognitivism, and constructivism and has become the standard for instructional design models.
