Another level of efficiency is accomplished through providing clear objectives . A vague objective, such as "Understand the diseases of the heart" is useless for a student given 5 weeks to learn the topic when, in Canada, the training program for cardiology is 6 years and the vague objective used in this sentence could be interpreted to the level of a cardiologist ... an objective that is impossible to achieve in 5 weeks. Clear and detailed objectives provide guidance and increased efficiency of learning. A common rebuttal to providing detailed objectives is the claim that students will only learn what they need for the exam and will learn nothing outside of the objectives. Compared to a curriculum with vague objectives , I have yet to see evidence of this claim and further believe that an overall curriculum that stimulates an active and enjoyable learning atmosphere will promote enthusiasm for learning beyond the objectives. Of course, with a vague objective, who can define what is "beyond" the realm of the objective when the margins are so blurred?
