Final answer:
Knowing instructional objectives helps students understand what is expected of them and guides their studying efforts, focusing on essential lesson components.
Step-by-step explanation:
Students are most likely to benefit from knowing the instructional objectives of a lesson because objectives tell them what is expected of them and so can help them direct their studying efforts. Rather than predicting specific grades or exam questions, instructional objectives serve to guide students in focusing their attention on the essential components of the lesson's curriculum. These objectives are usually designed to be measurable, providing a clear target for students to aim for as they progress through the course material.
