Pre-College Engineering Education
One of the goals of STEM integration in pre-college classrooms is that students can make connections within and between the STEM disciplines. Previous research about evidence-based reasoning (EBR) has suggested that this practice might help students make these kinds of connections. We have defined EBR as the practice of justifying engineering design ideas and decisions. EBR is the engineering component of the Next Generation Science Standards (NGSS) practice of engaging in argument from evidence; it is parallel to the science practice of scientific argumentation. The purpose of this study is to explore the types of STEM topics that students brought up when they were practicing EBR. In this project, we are interested in answering the following research question: While generating a solution to an engineering design problem in an engineering design-based STEM integration unit, what STEM content do elementary school students discuss?
We explored audio transcripts of one 5th grade student team while they were participating in a two-week long STEM integration unit. In the unit, Survival Suits, the engineering problem is for students to design a suit that will enable humans to survive in different habitats; students consider each suit design feature based on animal adaptations. In this study, we focused on the portion of the unit when students were participating in the solution generation phase, which included three full class periods of audio transcripts. Because this engineering design challenge did not allow students to actually construct a suit prototype, the conversations analyzed in this study included only planning an initial design and a redesign. In a first level of analysis, instances of EBR were identified in the audio transcripts; a revised version of Toulmin’s Argument Pattern was used to assist identification of EBR. In the second level of analysis, these instances of EBR were analyzed via open coding to determine the STEM content topics students talked about when justifying design ideas and decisions.
Preliminary results show that the students used content knowledge from all four STEM disciplines during instances of EBR. Students referred to science related to animal adaptations, habitats, and properties of materials, as well as mathematics about measurement and data analysis. For technology, they talked about experiences they had with existing real-world technologies. In relation to engineering, the student team discussed several topics during EBR: design, material type, functionality, structure, ease of use, and aesthetics. These results are evidence of students’ ability to integrate content knowledge from STEM disciplines when justifying their design ideas and decisions during an engineering design-based STEM integration unit.
