The paper reports about a study that examines changes in teachers' incorporation of epistemic practices in their design of engineering lessons and compares them to their views about the nature of engineering knowledge across 100 hours of professional development. Nineteen K-8 teachers in the USA, who were new to teaching engineering as part of a…

With school populations across the country becoming increasingly representative of students from diverse cultural and linguistic backgrounds, new considerations must be made to promote equitable and engaged science learning for all students (National Academy of Science, National Academy of Engineering, & Institute of Medicine [NAEEM], 2011).…

The vision of the Framework and NGSS requires important shifts in teaching approaches and instructional materials. We argue that this commitment to engaging learners in meaningful practice and supporting students' epistemic agency entails that we support "coherence from the students' perspective." This coherence arises when students see…

We report on one teachers' efforts to re-design an entire instructional unit as a coherent storyline about forces and motion as a part of a multiyear professional development (PD) project around the NGSS. Designing coherent storylines demands that teachers create opportunities for students to meaningfully engage in science practices in order to…
