Here are some examples of learning objectives and how they can be written better:
Understand is not a measurable verb; however, the intent of the instructor was to have the students be able to describe, which is measurable.
Describe and create are two different levels of learning, and it’s strongly suggested that you avoid having more than one action verb. Create is a higher level of learning than describe, therefore it can be assumed that you will be able to describe the process prior to applying it.
Understand is not a measurable verb, and it is too broad.
