Choice theory identifies five psychological needs: survival, freedom, power, belonging, and fun (Glasser, 1998). There are close parallels with self-determination theory (SDT), which specifies autonomy, competence, and relatedness as essential needs (Deci & Ryan, 2000). This case study examines a very successful example of choice theory enacted in a Grade 3 class. Despite no training in either choice theory or SDT, the teacher blended all the dimensions of these theories to provide a supportive learning environment in which mutual trust was key.
