Developing instruction is a critical part of the education process. For instruction to be effective it should be organized and well planned. Development of an effective program should include careful consideration of the need for instruction, the audience, and the course content. Instruction delivered via telecommunications can be even more complex and therefore best developed using a structured, systems approach. Most instructional development processes include four basic stages: instructional design, development, formative evaluation, and revision. During the design phase, a needs assessment is performed to determine the need for instruction, analyze the audience, and establish instructional goals. Development entails developing specific objectives for each goal, developing content to meet the objectives, and developing or selecting materials and methods. Formative evaluation includes the development of an evaluation strategy and the collection and analysis of evaluation data. The revision phase entails revising those aspects of the program that were shown to need improvement. This brief guide provides an overview of the instructional development process and guidelines for each of the four basic stages. (DB)
