The Nexus Of Ideation And Engagement Through Tower Crane Construction, Abigail Erskine, Hillary Ongoyo Omoze
The Nexus Of Ideation And Engagement Through Tower Crane Construction, Abigail Erskine, Hillary Ongoyo Omoze
Indiana STEM Education Conference
In this study, we investigate how the integration of collaborative design activities during group-based ideation influences middle school students’ engagement in STEM education. Central to this inquiry is a hands-on activity focused on the construction of a tower crane with a suspended bucket. Students developed a plan for the tower crane construction through collaborative sketches and discussion of ideas with teammates. This research brief provides implications for the impact of collaborative ideas generated by students in groups and choices in designs on student engagement.

Integrated Stem Education And Students' 21st Century Skills, Jung Han, Yunjin Lim, Woongbin Park, Kyongson Park
Indiana STEM Education Conference
This research investigates the impact of integrated STEM education on students' 21st century competencies, aiming to enhance science and engineering design teaching within a local design-based context. Specifically, the project targets high school students in a rural area and utilizes local contexts, including local rural knowledge and indigenous science knowledge, to facilitate STEM learning. The collaborative effort involves partnering high school environmental science and Technology and Engineering Educators, leveraging their diverse content expertise to teach students collaboratively as a science-technology and engineering teacher pair. Furthermore, university faculty members and industry partners provided support to create a STEM community of practice. …

Implementing Integrated Stem Forensic And Soil Sciences Lab Activities To Promote Interest In Stem Careers, Mariah K. Stollar Awan, Caroline J. Rakowski
Indiana STEM Education Conference
We implemented forensic and soil science integrated STEM lab activities with 11 middle school youth at a 4-H day camp at Purdue University. STEM perceived knowledge increased overall for participants. However, the pre- and post-assessments did not show a statistically significant difference. More students also indicated STEM career interest after participating. Because this study was exploratory and had a small sample size, more research on these integrated STEM lab activities should be conducted with larger samples.

The Future Of Future City: A Stem Program, Jeffrey A. Nowak, Shelby Werling
Indiana STEM Education Conference
The idea of integrating science, technology, engineering, and mathematics (STEM) is still an enigma for many educators (Dare et al, 2021). Recent academic standards favor curricula that interweave the principles of integrated STEM into all content areas. Finding a “one size fits all” curriculum is challenging, perhaps even impossible. Future City is a national program that specializes in hands-on cross-curricular STEM education. Students work collaboratively using an engineering and design process to showcase their solutions to citywide sustainability issues. This research brief examines how educators can utilize the Future City program as the cornerstone of their STEM curriculum.

The Impact Of Geospatial Contexts And Out-Of-School Experiences On Students' Stem Identity Formation, Hillary Ongoyo Omoze, Abigail Erskine, Asenath Odondi
Indiana STEM Education Conference
STEM teaching faces challenges in varied geospatial contexts (Mulvey et al., 2023), where place and space factors play a significant role. This research brief explores the influence of place and space in shaping students' STEM identities throughout their educational journey, with a specific emphasis on the role of out-of-school experiences in fostering student learning and interest in STEM careers, particularly among middle school students.
