Abstract Background STEM identity has been shown to have a powerful role in an individual’s success in educational environments, as well as on their career goals and trajectories. Historically, however, STEM identity formation for underrepresented students has been hampered by the lack of representation of in STEM fields, which predominantly consist of white males. One educational challenge is diversifying STEM classrooms, both in terms of the students themselves and also in terms of the science and scientists they learn about. Methods We piloted a 4-credit History, Philosophy, and Sociology of Science course at Michigan State University. Students were tasked with creating exhibits focused on themes of diversity and inclusion in science for a real client. Using a STEM identity survey, we assessed students’ attitudes towards the sciences, issues of diversity in science, and their sense of belonging to their educational communities. We also had the students respond to various short-answer questions throughout the semester to better understand their experiences working on a collaborative authentic learning task. Results Our results suggest that authentic learning experiences based around ideas of diversity and inclusion can help students develop sense of belonging and positive STEM identities. Students demonstrated shifts in their self-identities as scientists, focusing more on the intersection between their gender, ethnicity, and self-perception as a scientist. Through qualitative analysis of short-answer questions, we were able to ascertain that working in groups in an authentic learning environment helped the students improve their communication and collaboration skills. Conclusions Students’ increased focus on gender and ethnicity suggests that they are thinking critically about how their personal identities intersect with their scientific identities. Additional research would help us better understand if the coupling of authentic learning and inclusive teaching practices have significant impacts on the formation of students’ STEM identities.

This study was performed as an adjunct to an existing clinical study to validate the effect of veneer: framework thickness ratio on stress distribution in an implant-supported all-ceramic fixed partial denture. Two commercially available titanium dental implants with corresponding customized abutments and a patient-retrieved all-ceramic fixed partial denture were scanned using a high-resolution micro-CT scanner. Reconstructed 3D objects, along with a simulated bone surface, were incorporated into a non-manifold assembly and meshed simultaneously using Simpleware software (Synopsys Simpleware ScanIP Version P-2019.09; Mountain View, CA). Three such volume meshes (Model A, Model B, Model C) corresponding to veneer: framework thickness ratios of 3:1, 1:1, and 1:3 respectively were created, and exported to a finite element analysis software (ABAQUS). An axial load of 110 N was applied uniformly on the occlusal surfaces to calculate the static stresses and contour plots were generated in the post-processing module. From the data obtained, we observed optimum stress distribution in Model B. Also, the tensile stresses were concentrated in the posterior connector region of the prosthesis in all three models tested. Within the limitations of this study, we can conclude that equal thickness of veneer and framework layers would aid in better stress distribution.
