A common learning outcome is that the student will know the meaning of XYZ. This example shows an assessment for the log function.
Professionals should know the meaning of a “main idea.” In math, the log function is a main idea. Thus, it is useful to have an assessment task to quantify how well students know the log function.
This assessment task arose when I noticed that the log function appears in equations used in fluid dynamics. I envision using this in a fluids class when the log function appears in a commonly used equation in fluid mechanics.
The Assessment Task
The assessment task is given below. Conditions: Closed book, closed notes, closed calculator. Rationale: See if the student understands that the log is the inverse of the exponential function.
The feedback, shown below, reflects how I solved this problem when I encountered it.

Please share any ideas you have with our community by posting below. Address any topics you’d like. Or, address my questions.
- Do you believe that students should know main ideas? Is the log function a main idea?
- Is this an idea that an engineering student should know? Or should they just know how to punch the numbers into their calculator?
- What aspects of the assessment task do you like? Why?
- How can I make this assessment task better? Do you have specific ideas for me?
