This poster paper explores how teachers and researchers in a research-practitioner partnership utilize a rubric to evaluate lesson plans in terms of the integration of culturally relevant computer science. Results include that teachers felt able to include opportunities for cultural competence but indicate that additional support is necessary to include opportunities for cultural critique and conceptions of knowledge. The poster presented at this conference will highlight additional supports that teachers may need to develop culturally relevant computer science lesson plans. 

While national frameworks call for the integration of science, technology, engineering, mathematics, and computer science (STEM+CS) in K-12 contexts, few studies consider elementary teachers’ perceptions of implementing STEM+CS projects in science classrooms. This single case study explores elementary science teachers’ perceptions of enacting STEM+CS curricular materials. Survey and interview data were collected over the four-week project and qualitatively coded. Findings demonstrate teachers’ reported struggles to implement unfamiliar disciplines and leverage students’ prior knowledge in familiar disciplines as well as unanticipated consequences of instructional decisions based on perceived student engagement and pacing. Results underscore the value of teacher voice for curricular and professional development and highlight the need for further investigation of how teachers’ perceptions may influence enactment of STEM+CS curricular materials. 

Recent science education reforms, as described in the Framework for K-12 Science Education (NRC, 2012), call for three-dimensional learning that engages students in scientific practices and the use of scientific lenses to learn science content. However, relatively little research at any grade level has focused on how students develop this kind of three-dimensional knowledge that includes crosscutting concepts. This paper aims to contribute to a growing knowledge base that describes how to engage students in three-dimensional learning by exploring to what extent elementary students represent the crosscutting concept systems and system models when engaged in the practice developing and using models as part of an NGSS-aligned curriculum unit. This paper answers the questions: How do students represent elements of crosscutting concepts in conceptual models of water systems? How do students’ representations of crosscutting concepts change related to different task-based scaffolds? To analyze students’ models, we developed and applied a descriptive coding scheme to describe how the students illustrated the flow of water. The results show important differences in how students represented system elements across models. Findings provide insight for the kinds of support that students might need in order to move towards the development of three-dimensional understandings of science content.
