Force concept inventory

- D. Hestenes, M. Wells, Gregg Swackhamer
- Physics
- 1 March 1992

Every student begins physics with a well-established system of commonsense beliefs about how the physical world works derived from years of personal experience. Over the last decade, physics… Expand

Toward a modeling theory of physics instruction

- D. Hestenes
- Physics
- 1 May 1987

An analysis of the conceptual structure of physics identifies essential factual and procedural knowledge which is not explicitly formulated and taught in physics courses. It leads to the conclusion… Expand

The initial knowledge state of college physics students

- Ibrahim A. Halloun, D. Hestenes
- Physics
- 1 November 1985

An instrument to assess the basic knowledge state of students taking a first course in physics has been designed and validated. Measurements with the instrument show that the student’s initial… Expand

Common sense concepts about motion

- Ibrahim A. Halloun, D. Hestenes
- Physics
- 1 November 1985

Common sense beliefs of college students about motion and its causes are surveyed and analyzed. A taxonomy of common sense concepts which conflict with Newtonian theory is developed as a guide to… Expand
