The purpose of this action research project was to collect both qualitative and quantitative data to acquire information in teacher efficacy from the viewpoint of teachers themselves so that pedagogical practices could be enhanced to better serve the special needs student population. In this study, the relationship between teachers' perception of their pedagogical knowledge and beliefs and teachers' sense of self-efficacy was examined. This particular study was aimed at helping general and special education teachers understand, develop, and implement pedagogical practices that would increase their ability to educate students with special needs. The findings from this study revealed a substantial relationship between the components of teacher confidence in implementing pedagogical practices and teacher self-efficacy. Implications for teaching students with special needs are discussed. [The dissertation citations contained here are published with the permission of ProQuest LLC.
