Brief summary

Using a randomized control design, this study seeks to develop and evaluate a nutrition intervention to increase Montessori teachers' nutrition knowledge, nutrition self-efficacy, nutrition teaching self-efficacy and cultural food competence to improve teachers' eating behaviors, nutrition teaching practices, classroom food practices, and teacher-parent communication. This study will examine the feasibility and efficacy of a nutrition intervention for teachers which will include a nutrition education program via an online platform and hands-on Montessori-based curriculum to teach nutrition in the classroom. Teachers from multiple schools will be recruited using the public national Montessori listserv. This study will enhance teachers' nutrition knowledge which may increase their nutrition teaching practices and improve their personal nutrition habits. Improving teachers' personal and classroom nutrition practices may improve teachers' personal health outcomes and may positively impact their students through modeling of healthy behaviors and improving the classroom food environment.

Interventions

BEHAVIORALThe Teacher Education and Classroom Habits (T.E.A.C.H.) Program

The T.E.A.C.H. Program utilized essential constructs of the Social Cognitive Theory to deliver virtual nutrition education to Montessori teachers over a 6-week period. The intervention consisted of four program components: 1. An interactive online nutrition education platform with 6 modules was developed using a WordPress website. Each module contained 5 topics including adult nutrition, child nutrition, classroom food practices, cultural practices, and teacher-parent communication. Teachers were provided login information via email containing a unique identifier to be used as their username and were prompted to complete one module per week for 6 weeks; 2. Live weekly virtual education sessions were held via Zoom to supplement and reinforce the online learning experience; 3. A Montessori-based nutrition curriculum with 6 weekly lessons to utilize in the classroom was provided to each participant; 4. Educational handouts to be disseminated to parents.
