This study used a cluster randomized controlled trial to investigate the effectiveness of two approaches to increasing middle school students' science learning when using an inquiry-based science curriculum. Eighty-nine schools, with 253 teachers and 20,591 students, were randomly assigned into one of three conditions: (a) a treatment condition in…

Approximately 2 million students take Advanced Placement (AP) examinations annually. However, departmental policies that allow students to replace introductory courses with AP credit greatly vary within and across universities, even across relatively similar universities. This study examines the impact of AP credit policies on second-course…

The Framework for K-12 Science Education and the Next Generation Science Standards propose that students learn core ideas and practices related to engineering as well as science. To do so, students will need high-quality curricular materials designed to meet these goals. We report an efficacy study of an elementary engineering curriculum,…

Developing understanding of models and proficiency with modeling practice is challenging for both teachers and students. This 2-year study first investigated existing instructional strategies employed by teachers while teaching Earth and Space Science with dynamic physical models. Summer professional development introduced a conceptual framework,…

Research on translanguaging in science and engineering education has grown rapidly. Studies carried out across diverse contexts converge in their commitment to fostering equity in science and engineering learning for linguistically marginalized learners. However, the rapid growth of this research area has exposed different approaches to…

Affect is associated with success and persistence in STEM courses and degree programs. Measurement tools that produce valid and reliable data are essential to capturing the impact of evidenced-based instructional practices and reformed curricula on learning. We report the development of the Achievement Emotions Questionnaire for use in…

The ability to design and interpret controlled experiments is an important scientific process skill and a common objective of science standards. Numerous intervention studies have investigated how the control-of-variables-strategy (CVS) can be introduced to students. However, a meta-analysis of 72 intervention studies found that the opportunity to…

Design-based learning (DBL) offers opportunities to support students' content understanding. Previous DBL studies reported different effect sizes by using the data from one participant group. The goal of this study was to conduct a meta-analysis that would give a comprehensive picture of how DBL is connected to student achievement in different…

Strong spatial skills are foundational in predicting students' performance in science, technology, engineering, and mathematics education. Decades of research have considered the relationship between thinking spatially and how scientists reason and solve problems. However, few studies have examined the factors that influence improvement in…

This study explores the role of unconventional forms of classroom assessments in expanding minoritized students' opportunities to learn (OTL) in high school physics classrooms. In this research + practice partnership project, high school physics teachers and researchers co-designed a unit about momentum to expand minoritized students' meaningful…

This paper examines students' achievement and interest and the extent to which they are predicted by teacher knowledge and motivation. Student achievement and interest are both considered desirable outcomes of school instruction. Teacher pedagogical content knowledge has been identified a major predictor of student achievement in previous…

Recent calls for reform in K-12 science education and the National Academy of Engineering's Grand Challenges for Engineering in the 21st Century emphasize improving science teaching, students' engagement, and learning. In this study, we designed and implemented a curriculum unit for sixth-grade students (i = 1305). The curriculum unit integrated…

Te Kotahitanga is an educational reform project in Aotearoa/New Zealand demonstrated to have significantly impacted the participation, achievement, and retention of indigenous Maori students in secondary schools. In this paper, I share results from a study of culturally responsible mentoring at 4 different schools participating in the Te…

The first three years of science teachers' careers is an especially formative period, yet there remains only a limited literature base to support teacher educators who work with this population. Teachers in the induction phase benefit from professional development experiences that support them as they continue to learn about teaching by analyzing…

Even though school administrators and their leadership practices are rarely explored within science education research, our recent efforts to understand organizational influences on achievement disparities induced an elevated regard for elementary school principals. In this paper, we report on policy buffering by principals at schools whose…
