This dissertation explores how early research in self-efficacy, teacher stress, and teacher job satisfaction directly relate to self-determination theory. Specifically, the role of the elementary school principal can directly impact teacher motivation when meeting teacher basic psychological needs outlined in self-determination theory; connectedness, competence and autonomy. Furthermore, principals can build teacher connectedness, competence and autonomy with interactions and feedback both inside and outside of the formal teacher evaluation process. When principals interact with teachers frequently, visit classrooms weekly, and provide specific and timely feedback, teachers experience higher levels of motivation through increased feelings of connectedness, competency, and autonomy.
