Background: Since the advent of the Next Generation Science Standards (NGSS), there has been an increasing focus on engineering in K-12 education. As educators and researchers have gained a better understanding of the nature of engineering in the decade following the release of the NGSS, there are new opportunities for growth and complexity.…

The flue gas from waste incineration power plants contains high-level zinc species that may deactivate the catalyst for selective catalytic reduction (SCR) of nitrogen oxides (NO[subscript x]) with NH[subscript 3]. A comparison experiment was designed to investigate the effect of different types and Zn/Ce molar ratios on the performance of…

Drawing on racial battle fatigue as theoretical framing and critical race methodology, we offer the counterstories of 16 Black men doctoral scientists and engineers who relied on same race peer support to successfully persist in their science and engineering (S&E) doctoral programs. Our analysis of narratives and interviews yielded three…

Using critical race methodology as a methodological framework, this paper explores how 16 Black men PhD scientists and engineers describe their undergraduate and graduate school choices and how race and racism influenced these processes. Our analysis yielded two descriptive themes focused on counterspaces for Black men in science and engineering…

In this article, it is argued that processes of co-production can support teachers and students in organizing resources for justice through science learning. Drawing upon a critical justice conceptual framework, critical ethnographic data from one urban middle school classroom during a unit focused on engineering for sustainable communities were…

Understanding how engineering design (ED) and design-based learning (DBL) are portrayed at various educational levels is essential in this transition to ascertain the state of the literature. We investigated ED and DBL studies in Web of Science and Scopus databases. Then we focused on educational levels, categorizing research based on participant…

What is engineering? What do engineers do? How is engineering related to, but distinct from, science? These questions all relate to the nature of engineering (NOE), and as engineering is incorporated into K-12 education across the United States, the NOE is becoming increasingly important for students and teachers. While many policy documents call…

This study aimed to examine how students managed conflicts in an engineering design process and how different management styles affected their group interaction progress. We observed three groups of students in classes, where they designed devices to solve water shortages. Students' interactions involving conflict in these lessons were analyzed in…

Scientific and technological research is important to everyone because their results affect humanity worldwide. Although science and technology bring many benefits to humanity, individuals and societies can face the negative consequences of science and technology. To prevent and solve the negative consequences of research in these fields, it is…

Clinical immersion experiences provide engineering students with opportunities to identify unmet user needs and to interact with clinical professionals. These experiences have become common features of undergraduate biomedical engineering curricula, with many published examples in the literature. There are, however, few or no published studies…

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…

With the release of Framework for K-12 Science Education (National Research Council, 2012) and Next Generation Science Standards (2013) documents, engineering was integrated into science teaching. With that emphasis, teachers require to incorporate engineering practices and nature of engineering into their practice. Most of the attention has been…

Knowledge-producing practices in sciences and engineering increasingly use computational means for modeling and working with data. Despite consensus regarding the importance of computational thinking in science and engineering, scholars differ in conceptualization of the primary purposes and role of its integration in K-12 science (Kafai &…

Aim/Purpose: This paper highlights an innovative and impactful online operating system algorithms e-learning tool in engineering education. Background: Common teaching methodologies make it difficult to teach complex algorithms of operating systems. This paper presents a solution to this problem by providing simulations of different complex…

Transdisciplinary learning--where students develop and apply knowledge from multiple disciplines to solve open-ended problems--is necessary to prepare students for the most pressing real-world problems. Because transdisciplinary education often requires reimagining the content and design of undergraduate science courses, it can be a challenge for…
