Abstract Teacher leaders influence their peers by introducing innovative instructional methods and enhancing teaching quality. They have proven invaluable to school principals as they prioritize comprehensive teacher development, bolster teacher effectiveness, and promote teacher retention. Despite their importance, little to no research—prior to the present study—has shed light on the development of teacher leaders and the evolution of their leadership identity. While science, technology, engineering, and mathematics (STEM) teacher leaders offer a potential remedy for attrition in public schools, a substantial gap exists in understanding how a STEM teacher's self‐efficacy, values, and agency contribute to their transformation into effective STEM teacher leaders, especially in urban‐like learning environments. The present study focuses on STEM teacher leadership identity development and the challenges encountered. It ascertains the interplay between urban‐like learning environments, self‐efficacy, agency, the teacher leader's role within the school, and values in forecasting STEM teacher leadership identity. This research involved 100 in‐service PreK‐12 public school STEM teacher leaders. It yielded significant, positive, and meaningful relations between urban‐like learning environments, self‐efficacy/agency, teacher leader role, values, and STEM teacher leadership identity. These findings can enhance various facets of PreK‐12 STEM education, including educational programming, teacher training, and cultivating STEM teacher leadership. 

In order to promote justice-centered making in STEAM classrooms, the NASA Landsat-based Science and Technology Education for Land/Life Assessment (STELLA) instrument is proposed as an affordable educational tool for students to collect and analyze data pertaining to vegetation health, surface temperature, and air quality. This instrument can be used to investigate justice-centered, community-based problems and promote civic engagement toward policy change for a healthier world. Our study applies the MakerTPICK theoretical framework to a qualitative study to explore changes in teacher beliefs about the STELLA instrument following three justice-centered STEAM-making activities pertaining to urban heat islands, air quality, and vegetation health. The implications of this research can be used to inform professional development and promote justice-centered learning in the STEAM classroom. 

This paper examines the integration of justice-centered making into STEM teacher preparation programs, focusing on how these programs can foster equity and inclusivity while acknowledging the need for more research on the overlapping areas of STEM teacher preparation, social justice, and makerspace. Therefore, I synthesize recent literature in the overlapping areas and identify how each component brings insight to purposeful activity, identity formation, and connection. The discussion leads to how utilizing justice-centered-making activities can prepare educators to address systemic inequities in STEM fields. The implications of these pedagogical approaches for both teachers and students are discussed.
