> It's easy to grade a test if you just look for right answers, and mark everything else off. It's easy to grade labs if you just look for the circuit tracking the input frequency. Grading either based on some assessment of how well the student understands what's actually happening is much, much harder. The professor I had for Networks and Linear Systems had an interesting approach to that. He developed every test problem such that the input values were small, whole numbers. If you did the problem right, your answers would also be small whole numbers. If you went off into the weeds, you would get really weird answers. That was both a hint to the student that they were barking up the wrong tree and a guide as to where the solution broke down.
