Examining S-T-E-M Teachers’ Design of Integrated STEM Lesson Plans

Abstract

AbstractReform efforts in different parts of the world call for the adoption of integrated approaches to STEM education. However, little is known about how teachers work, as members of learning communities, to design STEM teaching material such as lesson plans. To address this gap in the literature, we examined the design of STEM lesson plans by in-service secondary teachers (n = 26) from all S-T-E-M disciplinary backgrounds who participated as members of a learning community in the context of a 7-month professional development program comprised of 13 small-group sessions. STEM lesson plans were analysed based on the key characteristics of a conceptual framework of integrated STEM, and the teachers’ identified interdisciplinary elements were analysed through the boundary objects framework. The qualitative content analysis produced four main findings: (a) divergencies take place at the disciplinary level when teachers design STEM lesson plans; (b) teachers coming from different disciplines have different positioning regarding specific integrated STEM key characteristics; (c) the type and sequence of instructional activities served as a boundary-design practice; (d) the nature of the boundary objects that teachers identify in order to teach integrated STEM differs according to the discipline. The findings of the study shed light on teachers’ understanding and needs at the disciplinary level and call for specially designed STEM professional development programmes that provide explicit opportunities for disciplinary boundary crossings.
