A Meta-Synthesis Of The Literature On Science And Engineering Teaching Self-Efficacy: Current Gaps And Future Research Directions, Deepika Menon, Jeanna R. Wieselmann, Sarah Haines, Sumreen Asim Jan 2024

A Meta-Synthesis Of The Literature On Science And Engineering Teaching Self-Efficacy: Current Gaps And Future Research Directions, Deepika Menon, Jeanna R. Wieselmann, Sarah Haines, Sumreen Asim

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Self-efficacy is a topic of great interest in elementary preservice and inservice teacher education given that elementary teachers often have low self-efficacy for STEM teaching. In this article, we synthesize the existing literature on science and engineering teaching self-efficacy to (1) explore trends in science and engineering teaching self-efficacy research, (2) identify current gaps that exist in the literature, and (3) propose a visual model to provide future direction in research. Utilizing a qualitative meta-synthesis, we analyzed 88 articles focused on science and engineering teaching self-efficacy. Of these articles, 66 studied preservice teachers, 21 studied inservice teachers, and one included …

Introduction: TPP Problem of Practice

Preparing Science Teachers for Teaching in Culturally Diverse Schools ● National average of 70% higher science teacher turnover in Title I versus non-Title I schools (Carver-Thomas & Darling-Hammond, 2017). ● Mismatch between teacher and student demographics; national teacher workforce is overwhelmingly white (and female) and a student population that has become increasingly racially and ethnically diverse. ● Longer, supervised teacher preparation internships have been linked to higher retention rates of new teachers (Carver-Thomas & Darling-Hammond, 2017), but… with more science teachers retiring, there are also fewer master science teachers to mentor preservice teachers.

Context: Our …


Investigating Preservice Secondary Teachers’ Understanding And Enactment Of The Standards‑Based Practices During Microteaching, Deepika Menon, Diana S. Chang, Rosetta W. Ngugi Jan 2024

Investigating Preservice Secondary Teachers’ Understanding And Enactment Of The Standards‑Based Practices During Microteaching, Deepika Menon, Diana S. Chang, Rosetta W. Ngugi

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Reform efforts in K–12 science education have been gaining pace ever since the introduction of the Next Generation Science Standards (NGSS). The new vision calls for reconsidering teacher preparation programs to prepare future teachers who are confident and competent in delivering NGSS-based instruction. This study investigated the development of 27 preservice secondary science and mathematics teachers’ (PSTs’) knowledge and skills as they understand, interpret, and implement the NGSS, particularly science and engineering practices (SEPs), within the context of microteaching during a STEM methods course. Primary data sources include 12 videos of 40-minute-long microteaching lessons, self-reflections, semistructured and focus-group interviews, and …
