Deciding when problems should not be fully defined

Undergraduate course redesign · materials science

From an engineering perspective, real design work rarely starts with a neatly framed problem. Engineers begin with an objective, a set of constraints, and incomplete information, and they have to decide what matters before deciding what to calculate. Choosing a material is less about applying a single formula than about weighing tradeoffs among strength, weight, cost, manufacturability, and environmental conditions.

The mismatch

The course at the center of this case was intended to prepare students for that kind of reasoning. In practice, its structure rewarded something else. Lectures pushed for coverage, and exams rewarded speed and correctness once someone else had done the hard work of framing the problem.

The decision

The key decision was whether to keep a course structure that made it easy to cover material or to redesign it around the kinds of problems engineers actually face. The course was reworked to prioritize making decisions under real constraints rather than completing well-defined procedures.

Students worked in groups on realistic scenarios that required them to make choices rather than follow instructions. They identified what information mattered, compared material options against competing requirements, and justified their decisions based on evidence.

Instead of rewarding students for moving quickly through problems someone else set up, the course asked them to slow down, weigh constraints, and defend choices that had consequences. That shift made the work harder, but it also made it more honest. Students were no longer practicing for exams. They were practicing how to decide.
