[1] Paul G. Hewitt popularized this approach with his textbook Conceptual Physics: A New Introduction to your Environment in 1971.
Conceptual Physics: Matter in Motion by Jae R. Ballif and William E. Dibble was published in 1969.
[5] In 1987 Hewitt wrote a version for high school students.
[7] Enrollment in conceptual physics courses in high school grew from 25,000 students in 1987 to over 400,000 in 2009.
[8] This approach to teaching physics has also inspired books for science literacy courses, such as From Atoms to Galaxies: A Conceptual Physics Approach to Scientific Awareness by Sadri Hassani.
