Which of the following is NOT considered a major part of the ISD model lesson plan?

The ISD (Instructional Systems Design) model provides a structured approach to lesson planning that ensures effective teaching and learning processes. Among the key components of a lesson plan, the introduction sets the stage for the learning experience, outlining objectives and engaging students. The body contains the main instruction, where content is delivered, and activities are conducted. The conclusion provides a summary and reinforces the lesson's key points.

Assessment, while critical to the overall learning process, is not traditionally classified as a major segment of the lesson plan itself. Instead, it often forms part of a broader instructional strategy to evaluate student understanding and effectiveness of instruction. Thus, while assessment is essential in measuring outcomes and guiding future instruction, it does not constitute a distinct section within the ISD model lesson plan.
