Kelley and Knowles (2016) also reported on how “educational researchers indicate that teachers struggle to make connections across the STEM disciplines” (p. 1). This appears to be the heart of the issue so it is here that we make our final recommendations, where we affirm what Lyons (2022) stated regarding the objectives and transdisciplinary nature of STEM as follows:
Having a Scope and sequence for primary STEM education is a positive step forward but such knowledge is best seen as provisional. To make a meaningful STEM unit of work, it must be conceptual and not merely factual or procedural. Factual and procedural learning is still important but STEM education is an opportunity to go deeply into conceptual topics. Our final recommendation is that exploring carefully chosen conceptual topics can help teachers and students to make important connections and enable them to become competent and functional in an increasingly complex world.
In addition to The 28 STEM units, a new unit on Circles and rotation as scaffolds for STEM education is available here. This units draws on some existing content from other units and combines it around the affordances of circles and rotation.
