Multiple studies call for engineering education to integrate social justice into classroom instruction. Yet, there is uncertainty regarding whether integrating these social topics into engineering curriculum will support or detract from the learning of technical concepts. This study focuses on evaluating how reframing technical assessments to include social justice concepts impacts student learning and investigates how well students integrate social justice into engineering decision making. Using a within-subject design, in which students were exposed to both conditions (questions with and without social justice context), we evaluate how social justice framing impacts overall student learning of technical topics. Social justice prompts are added to homework questions, and we assess students’ demonstration of knowledge of original technical content of the course, as well as their ability to consider social justice implications of engineering design. In the earlier homework assignment, the experimental group showed a significant decrease in learning when technical concepts were framed to include social justice. As the students became more familiar with social justice considerations, their learning of technical concepts became comparable to that of students who did not have the social justice components in their assignment. Their evaluation of the social implications of technical decisions also improved.

Students’ sound knowledge about osmosis can lead to their understanding of other related biological processes that require the movement of materials across cell membranes, such as photosynthesis, homeostasis, and cellular respiration. However, students have difficulties to understand osmosis. This challenge has been attributed to the abstract nature of the concept and the way it is presented to students. Thus, we present an engineering design, integrated biology unit in which students use the engineering design process to learn about osmosis and its related concepts. A dependent t-test revealed statistically significant differences in students’ understanding of osmosis and related concepts, and the engineering design process before and after the unit. Overall, in this unit students developed the understanding of osmosis in a real-world context through an engineering design process. 

Students often find it challenging to learn about complex and abstract biological processes. Using the engineering design process, which involves designing, building, and testing prototypes, can help students visualize the processes and anchor ideas from lab activities. We describe an engineering-design-integrated biology unit designed for high school students in which they learn about the properties of slime molds, the difference between eukaryotes and prokaryotes, and the iterative nature of the engineering design process. Using the engineering design process, students were successful in quarantining the slime mold from the non-inoculated oats. A t-test revealed statistically significant differences in students' understanding of slime mold characteristics, the difference between eukaryotes and prokaryotes, and the engineering design process before and after the unit. Overall, students demonstrated sound understanding of the biology core ideas and engineering design skills inherent in this unit.
