A formative evaluation of the American Cancer Society Changing the Course nutrition education curriculum.

A formative evaluation was conducted of Changing the Course, a behaviorally oriented, activity-based nutrition education curriculum for elementary students from the American Cancer Society, to assess feasibility of program implementation. Sixteen teachers in six schools in the Northeast taught the 15-16 session lower and upper elementary curricula to 702 students. Teacher satisfaction with the curriculum was high. Fidelity of implementation of the curriculum also was high and relatively few modifications to learning activities were made. Teachers reported the one day of training they received was adequate. They also reported a positive influence of the curriculum on themselves and their students. Student achievement results showed most children achieved most of the learning objectives at posttest--80% giving the correct answers on more than 75% of the test items. An examination of children's item-by-item answers on the posttest and of teachers' logs provided information useful for the final stages of development of the curricula and teacher training procedures, before national dissemination.
