Nearly a decade ago, the "Framework for K-12 Science Education" argued for the need to intertwine science and engineering practices, disciplinary core ideas, and crosscutting concepts in performance expectations. However, there are few empirical examples for how intertwining three dimensions facilitates learning. In this study, we used a…

This article reports on a design-based implementation research (DBIR) project that addresses the question: "How can classrooms be supported at scale to achieve the three-dimensional learning goals of the Next Generation Science Standards?" Inherent in this question are three key design challenges: (i) "three-dimensional…

In order to compete in a global economy, students are going to need resources and curricula focusing on critical thinking and reasoning in science. Despite awareness for the need for complex reasoning, American students perform poorly relative to peers on international standardized tests measuring complex thinking in science. Research focusing on…

Technology education should play a far more substantial role in schools. Defines the term technology and presents a comprehensive set of goals for elementary technology education. (Contains 30 references.) (Author/YDS)

In recent years, a number of curriculum reform projects have championed the notion of having students do science in ways that move beyond hands-on work with authentic materials and methods, or developing a conceptual grasp of current theories. These reformers have argued that students should come to an understanding of science through doing the…
