Determining how to increase practicing elementary teacher science instruction self-efficacy through ongoing professional development has been a problem in one urban Texas school district. Existing literature indicated science instruction self-efficacy could be built using professional development. However, there is a gap in the literature…

The "A Nation at Risk" report was released in 1983 and enumerated systemic flaws in the U.S. education system, highlighting science education as an area of concern (Denning, 1983). Over a generation later, a new opportunity has emerged to improve science education for all students, and especially the youngest learners. The Next…

This study examines teachers' and students' self-efficacy in the US and Egyptian context. More specifically, the study examines teachers' and students' self-efficacy in twelve classrooms; six in the US and six in Egypt. The research questions are formulated in order to understand the relationship between students' self-efficacy, their perceptions…

Teachers' self-efficacy influences their ability to teach students. Primary grade teachers (K-3) are tasked with teaching all content areas. K-3 teachers struggle with self-efficacy to teach science content rigorously and find the time to teach science through hands-on learning. This study addressed the gap in research for teaching science through…

As the need for a STEM-literate workforce grows, educators must prepare to develop STEM-literate thinkers. American educators must modernize teaching practices and utilize the best research-based STEM pedagogy. STEM education can no longer be a novelty or supplement to classroom instruction, and this is especially true in elementary classrooms.…

Science, Technology, Engineering, and Math (STEM) education is currently commanding an ever-greater share of our national dialogue about education. Very few STEM initiatives focus on studies involving in-service teachers; most education research involves preservice teacher candidates. This researcher used a 54 question survey to examine in-service…

This Mixed-Method Action Research study aimed to implement an extended Project-Based Learning professional development series with middle school science teachers. The professional development series took place during the teachers' Communities of Practice, offering them high-quality support, active participation, and content-specific conversations.…

Science, technology, engineering, and math (STEM) education is of global focus, demanding qualified mathematicians, technologists, engineers, and scientists from diverse settings. Addressing the STEM academic achievement gaps among secondary students from marginalized backgrounds is a central concern and focus addressed in my research because of…

The purpose of this study was to determine the impact of Snacks on secondary school students' science learning and science self-efficacy. This study also explored the relationship between teacher science self-efficacy and confidence. The study utilized thirteen (13) teachers participating in an inquiry science professional development that…

This causal comparative study examined differences between Modeling Instruction delivered through distance learning (DL) versus face-to-face (FTF) in terms of teachers' performance on professional development evaluation tools for content knowledge and self-efficacy. The theoretical foundation of this study included elements of professional…

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,…

This dissertation conducted a science classroom intervention using two instructional approaches, computational modeling and paper-based pictorial modeling, in the context of food webs. A series of research papers were written on the impact of the intervention on students' attitudes and learning, and on teachers via professional development and…

Open inquiry offers students the opportunity to gain 21st century skills and expose them to science practices advocated by Next Generation Science Standards (NGSS). While this raises the bar from lower-level inquiry classes, students initially struggle with open inquiry, because they do not know what to expect as they shift from a teacher-directed…

As K-12 computer science education mandates rapidly evolve across America, government officials, technology industry executives, and school leaders recognize such efforts' intellectual and economic importance. Specifically in Tennessee, a unanimous vote from the Tennessee General Assembly resulted in the passage of Chapter 979 of the Public Acts…

The nature and purpose of this study was to examine the self-efficacy of teachers who use an inquiry-based science program to provide authentic experiences within the elementary school setting. It is essential to explore necessary improvements to bring about effective science education. Using a mixed methods study, the researcher conducted…
