Which document is designed to guide students in specific areas of study?

The document that best serves the purpose of guiding students in specific areas of study is a study sheet. A study sheet typically condenses key concepts, important information, and points of focus tailored to a particular subject or topic, making it a practical resource for students as they prepare for exams or deepen their understanding of the material.

In contrast, a grading rubric provides criteria for evaluating assignments and does not focus on content learning; its main purpose is to communicate expectations related to performance rather than guiding students in their study practices. A lesson plan outlines the objectives, activities, and methods for teaching a particular lesson, primarily aimed at instructors rather than students. While a textbook contains comprehensive information on a subject, it is more of a reference source rather than a focused tool for guiding specific study activities.
