Explanation

Reality principle

Students can make sense of the situation based on their experience.

Model construction

The task creates a need for a mental model to be constructed, modified, extended, or refined.

Model documentation

Students are required to explicitly reveal how they are thinking about the problem.

Self-evaluation

The problem statement includes rubrics enabling students to judge for themselves whether their solution is acceptable.

Generalizable model

The model should not only work on the specific problem but should be sharable and usable in other situations.

Simple prototype

The problem should be as simple as possible given the instructional goals.
