 Creating future scientists, one student at a time

Yes, the Great Grow Along has been validated through use in thousands of classrooms over many years. A learner verification study completed in 1997 documented the effectiveness of the program in producing knowledge, attitude and behavior change among students.

Pre- and post-tests were used to evaluate the curriculum implemented in 4th-, 5th-, and 6th-grade classrooms in three states. Student learning outcomes were measured in cognitive, affective, and behavioral intention domains. Significant change, indicating effectiveness of the curriculum, was found in attitudes and in knowledge of nutrition and the scientific method. Seventy-five percent of student respondents reported that they had made or planned to make changes in food choices. All teachers used most of the curriculum activities and were generally positive about its usability.¹
