A course was developed to help science teachers in Mississippi teach physics. Most of those teaching the subject were inexperienced in physics, had limited background in the subject, and were in need of help. The course provided these teachers with a deeper understanding of physics principles, emphasized problem-solving strategies, and included many simple demonstrations and experiments. As a result of the course, a manual containing about 125 demonstrations and 25 experiments was developed. Criteria for selection of demonstrations and experiments included the following: (1) they should illustrate clearly and directly the concepts that teachers would normally include in their courses; (2) they should be simple to perform; and (3) they should require a minimum of expensive or specialized equipment. The manual has been enthusiastically received by Mississippi high school physics teachers and illustrates how an institution of higher education can be of significant service to high school teachers.
