There is an established need for well-qualified teachers in high-need school districts, which are often located in rural or urban communities, and those with significant populations of English language learners. Over the five-year duration of the project, the Colorado State University (CSU) Noyce Phase 2 Scholarship Program will prepare 24 new secondary science, technology, engineering, or mathematics (STEM) teachers educated in social justice. Each Noyce Scholarship recipient will be working toward or will have earned a bachelor’s degree in a STEM discipline, and will be enrolled in the CSU secondary teacher education program. Four CSU STEM colleges will work in partnership with local school districts, CSU Extension, and the 21 Colorado Boards of Cooperative Educational Services. The project will address three research questions to better understand the effectiveness of teacher preparation programs: (1) What is the longitudinal impact on recipients’ teaching self-efficacy, perceptions of STEM and STEM teaching, teaching ability, and self-efficacy as a teacher mentor? (2) What impacts do the Phase 1 and Phase 2 models have on secondary student perceptions of STEM and their STEM learning as well as recipients’ perceptions of their students’ learning? (3) What impacts does the Phase 2 model have on teacher mentor perceptions of STEM and STEM teaching, mentoring self-efficacy, and teaching ability? Dr. Sample McMeeking is a senior researcher on this project.
