Science education has been the focus of reform for years since the publication of the Next Generation Science Standards (NGSS) framework in 2013, which included eight science and engineering practices to enhance science literacy in students across the United States. Despite the attention science education has gained over the years, teachers still…

This study investigated how the figured world of the RET, and other figured worlds of science that teacher's experience, impacted their conceptions around the nature of science and their identities in science and as science teachers. The main premise behind RET programs is that by partnering science teachers with scientists as mentors, science…

The present dissertation in practice (DiP) proposal delineates an action research study designed to evaluate the use of problem-based learning (PBL) in an eighth-grade earth science class to assess the impact of PBL on student achievement. I have observed that students often struggle with developing an understanding of how the motions of the sun,…

Systematic studies on effectiveness of in-service teacher professional development (PD) are important for science education research and practice. Previous studies mostly focus on one certain aspect of the entire program, for example, effectiveness of PD on improvement of teachers' knowledge or students' learning outcomes. This study, however,…

Professional development for practicing science teachers has been a goal in education for the last two decades. Studies have shown that the quality of teacher instruction may be linked to teacher participation and involvement in professional development programs (Fishman, Marx, Best, & Tal, 2003). Furthermore, reflection during professional…

The purpose of this study is to understand how teacher identity influences elementary teachers' science practices from multiple perspective---the teacher's self-reported identity, the researcher's perspective, and the students' perspectives. Two frameworks on identity were synthesized and used in this research. The first, developed by Gee…

The purpose of this study was to describe Markdale High School's change from separate college preparatory and general level classes to heterogeneously-grouped classes in English, mathematics, science, and social studies, with particular emphasis on the principal's leadership style, change process, and teacher concerns (Hall & Hord, 2006)…

This qualitative case study explored a third grade bilingual teacher's transformative language ideologies through participating in a collaborative action research project. By merging language ideologies theory, Cultural Historical Activity Theory (CHAT), and action research, I was able to identify the analytic focus of this study. I analyzed…
