The purpose of this study was to examine the effectiveness of integrating self-reflection, focused instruction, and field practice in a semester-long language arts course in order to shift early childhood preservice teachers' (PSTs) beliefs and attitudes about writing instruction, as well as their development and planned use of tools for instruction. The findings revealed that a course focused primarily on preparing PSTs to teach writing can influence PSTs' definitions of writing, the importance they place on writing instruction, their self-efficacy related to teaching writing, and their tools for instruction.
