Which step of the four-step method of instruction introduces the lesson?

In the four-step method of instruction, the preparation step is crucial as it sets the stage for the entire lesson. This phase involves introducing the topic, outlining objectives, and engaging students' interests by connecting the material to their existing knowledge. It creates an environment conducive to learning by establishing what students will learn and why it is important, thereby fostering motivation and readiness to engage in the forthcoming content.

Following this step, the lesson progresses to the presentation stage, where the new information is conveyed, but it is in preparation that students receive the context and groundwork necessary for understanding. The evaluation step is more focused on assessing comprehension, and application pertains to practicing or reinforcing the concepts learned; neither of these serves the primary role of introducing the lesson's objectives and relevance. Hence, preparation is the correct answer as it plays an essential part in setting up the instructional framework.
