The Next Generation Science Standards (NGSS) reflect an ambitious vision for science education where students investigate phenomena or solve problems through using and applying disciplinary core ideas in concert with science and engineering practices and crosscutting concepts. Because the NGSS are so different from prior standards, the need for high-quality curriculum materials is especially great. As new curricula go to scale, it will be important to conduct evidence-based research on their efficacy. We conducted a randomized experiment to examine the efficacy of a widely available NGSS-designed middle school curriculum for improving seventh grade students’ learning in physical science. A hierarchical linear modeling approach was applied to analyze student learning outcomes as measured by an NGSS-aligned assessment. Initial findings demonstrate evidence of promise of the curriculum materials for supporting three-dimensional teaching and learning. The findings provide support for further research on NGSS-designed materials at other grade levels and within other science domains. 

In this paper, we report on our study of the implementation of an NGSS-designed middle school curriculum and how it fits into the larger context of a district system, including how it may be impacted by other system components (e.g., district support or teacher PL), and how these, in turn, may impact NGSS instruction in the classroom. This study was part of a larger randomized controlled trial that was conducted across four school districts with seventh grade science teachers and their students. We examined the nature of curriculum use and NGSS instruction in treatment and control conditions via instructional logs and surveys. 

Decades of motivation research have yielded a set of Motivation Design Principles (MDPs) that can be leveraged to support the development of student motivation and engagement in the classroom. This article addresses the translation of these guiding principles to teacher professional learning and subsequently, classroom practice. Drawing from published literature, as well as the experiences of a co-design team of motivation and science education researchers and middle school science teachers, we address the landscape of decision points for designing and implementing professional learning focused on supporting middle school students’ motivation in science. We identify 3 key decision points: (1) the extent to which professional learning should focus on general principles or specific practices; (2) the appropriate level(s) for translation of the MDPs into practice; and (3) the creation of opportunities for teacher reflection and self-assessment of their practice on student motivation and engagement.
