Engineering design that requires mathematical analysis, scientific understanding, and technology is critical for preparing students for solving engineering problems. In simulated design environments, students are expected to learn about science and engineering through their design. However, there is a lack of understanding concerning linking…

This research investigated how middle school science teachers integrated engineering into their planned science instruction and the extent to which they conceptually linked science to engineering following participation in a professional development program. Video recordings of six teachers' classroom implementation of teacher-designed units were…

Despite an increasing focus on integrating engineering design in K-12 settings, relatively few studies have investigated how to support students to engage in systematic processes to optimize the designs of their solutions. Emerging learning technologies such as computational models and simulations enable rapid feedback to learners about their…

Mechanistic reasoning about an artifact or system involves thinking about its underlying entities and the properties, activities, and cause-effect relationships of those entities. Previous studies of children's mechanistic reasoning about engineering solutions have mostly focused on specific mechanical systems such as gear trains. Yet there is…

"The Framework for K-12 Science Education" and the Next Generation Science Standards require teachers to integrate engineering design into K-12 science teaching. However, many teachers have no formal preparation in engineering design and how to integrate it into science instruction. Furthermore, few models exist for preparing teachers in…
