The format promotes coherence in the assessment.

Abstract

Designing a one-hour unit test for an introductory physics class can be quite challenging. We present an efficient format of a one-hour unit test that utilizes question groups for quantitative free-response problems and a binary system (True or False) for conceptual questions. This format promotes coherence and allows the instructor to test a wide variety of topics in a one-hour exam. For the 4 semesters in which the design has been implemented, average unit test scores have increased from 76% using traditional test format, to 79% using the efficient design.
