Children often make unhealthy food choices because they lack nutrition knowledge. This chapter consequently assessed the potential employment of a nutrition intelligent tutoring system (NutritionITS) for teaching and learning basic nutrition concepts in primary education. Following the K-12 Health Curriculum Guide by the Department of Education, NutritionITS incorporated the first quarter content in the grade 1 level. Using an exploratory sequential mixed methods design, it was evaluated by teachers and parents. The qualitative phase served as the participatory design process that extracted the features needed by teachers. On the other hand, the quantitative phase served as the prototype evaluation using the technology acceptance model constructs. The results presented in this chapter may assist educational leaders, teachers, parents, and students in achieving a better learning outcome in nutrition education. In addition to its contribution to the literature of educational research, this is the first study to develop an intelligent tutoring system in the field of nutrition science.
