The sense of efficaciousness for engaging diverse learners was examined with twenty-four pre-service teachers concurrently enrolled in a junior-level Creative Arts methods course and a field experience course with placements in K-2 general education classrooms. The pre-service teachers participated in music and literacy activities in their university class, then planned and implemented standards-based music activities in literacy lessons with their young students. In this case study, both quantitative and qualitative data were collected, including a teacher self-efficacy scale, an attitude survey, written reflections, interviews, open-ended responses, and lesson plans. Results demonstrated a significant increase in the pre-service teachers' self-efficacy in pre-post rating analysis and indicated that this project contributed to their efficacy in engaging and meeting the needs of diverse learners in elementary classrooms. The pre-service teachers demonstrated proactive classroom management and reflected upon their students' increased focus in class. The pre-service teachers indicated that their success with these types of projects encouraged them to plan for similar implementation with their future diverse learners; therefore, providing the potential to positively impact their future performance. Additionally, this project emanated Scholarship of Teaching and Learning (SoTL) by encouraging self-reflection; examining and applying effective teaching strategies; and advancing the field of teacher education.
