Learning content refers to the facts, principles, and concepts that are taught as part of the curriculum. It is the medium through which instructional objectives are accomplished. There are three key questions related to developing learning content: 1) What knowledge, skills, attitudes, or values are most worthwhile to teach? 2) Why are they considered worthwhile? 3) How will they be acquired by students? When selecting learning content, schools must make wise choices given the vast amount of knowledge available, focusing on only the most essential material.
