Bridging Disciplines: Exploring Interdisciplinary Curriculum Development in STEM Teacher Education

The global emphasis on interdisciplinary teaching continues to shape educational discourse, promoting meaningful and valuable learning experiences. This study examines the interdisciplinary curricular process led by a group of second-career teacher trainees and explores its role in shaping their emerging professional identities. The research focuses on eight high-achieving individuals transitioning to teaching as a second career through a STEM-focused (Science, Technology, Engineering, Mathematics) teacher preparation program. Employing a qualitative case study methodology, the study reveals a curricular process characterized by confusion and conflict as second-career teacher trainees navigate interdisciplinary integration. The findings highlight a planning process driven by conceptual and epistemic deliberations at both inter- and intra-disciplinary levels, with a predominant focus on disciplinary considerations over pedagogical aspects. The study further identifies key tensions that challenged participants’ perceptions, emotional responses, and instructional practices, offering a nuanced perspective on the complexities of interdisciplinary teaching. These insights contribute to a deeper understanding of professional identity formation among second-career teachers in STEM education.
