Schlendorf, Christine; Kelly, Angela M.; Krakehl, Robert – Journal of Geoscience Education, 2023
Student performance in high school Earth Science coursework often depends upon access to high quality teaching and resources. This study employed a non-experimental correlational research design to explore teacher-level and school-level variables and their relationship to students' Earth Science performance. The theoretical framework is derived…

Palermo, Martin; Kelly, Angela M.; Krakehl, Robert – Journal of Science Teacher Education, 2022
The issue of science teacher turnover has been examined in many national studies, yet most educational policies related to teacher preparation and student performance are determined at the state level. There has been a lack of research that explores this issue in specific science domains. The present nonexperimental longitudinal study examined…

Sheppard, Keith; Padwa, Linda; Kelly, Angela M.; Krakehl, Robert – Journal of Science Teacher Education, 2020
This empirical census study was a quasi-experimental analysis of certification level (primary vs. secondary) and in-field vs. out-of-field certification. The sample included chemistry teachers (n = 2312) and physics teachers (n = 1387) in New York State in 2011-12. Findings indicated that the number of out-of-field teachers was relatively low, but…

Krakehl, Robert; Kelly, Angela M.; Sheppard, Keith; Palermo, Martin – Physical Review Physics Education Research, 2020
Physics, as a foundational science, has particular importance in predicting the postsecondary success of students who major in science, technology, engineering, and mathematics. This quasiexperimental, observational study examined teacher-level and school-level predictors of student performance in physics, with a focus on isolated teachers. A New…
