Retrieval practice of a hierarchical principle structure in university introductory physics: Making stronger students

Introductory physics is taught to several hundred thousand university students every year. It is seen as especially difficult by many and the failure rate is often high. A relevant question is whether one can increase the success rate among the weaker students? Retrieval practice is an established l...

description	Introductory physics is taught to several hundred thousand university students every year. It is seen as especially difficult by many and the failure rate is often high. A relevant question is whether one can increase the success rate among the weaker students? Retrieval practice is an established learning strategy with large benefits.

Here we present a novel tool for retrieval practice in physics called the hierarchical principle structure for mechanics (HPSM).
