What is defined as a road map that guides the instructor in planning lessons?

The correct choice is a lesson plan because it serves as a detailed blueprint for the instructor, outlining the specific objectives, activities, and assessments for a particular lesson. It helps to structure the content in a way that aligns with the overall educational goals and ensures that all necessary information is covered during the teaching process. A well-crafted lesson plan not only presents the material to be taught but also anticipates potential questions or difficulties that students may encounter.

In contrast, the other terms refer to different aspects of the educational framework. A curriculum guide is more comprehensive and provides an overarching framework or outline for an entire course or program rather than focusing on individual lessons. An instruction manual typically provides guidance on using specific tools or equipment and is not targeted at lesson structure. Lastly, an assessment tool is designed to evaluate student performance or understanding and does not provide guidance on lesson planning. Therefore, the lesson plan is crucial for day-to-day teaching effectiveness, ensuring that instructors engage students appropriately and meet intended learning outcomes.
