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' values, beliefs, and self-confidence are critical components of decisions educators make every day. The purpose of the study was to examine the relationship between secondary science teachers' epistemology and self-efficacy on science instructional practices and conceptualization of student research experiences rooted in the Next…

Programming and automation continue to evolve rapidly and advance the capabilities of science, technology, engineering, and mathematics (STEM) fields. However, physical computing (the integration of programming and interactive physical devices) integrated within biomedical contexts remains an area of limited focus in secondary STEM education…

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.…

Next Generation Science Standards (NGSS) science and engineering practices (SEPs) involve commands of the English language in writing, speaking, reading, and listening. Language tasks embedded in NGSS SEPs require English learners (ELs) to develop science skills and understanding and language proficiency simultaneously. Sense of self-efficacy…

A mixed-methods research study was designed to examine teachers' knowledge and confidence for implementing a STEM-based problem-based learning (PBL) unit in their 6-12 grade science and math classrooms. Twenty-one teachers (7 in-service and 13 pre-service) participated in an intensive two-week summer workshop during which they engaged in, and then…

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 study was conducted to investigate eighth-grade science teachers' self-efficacy during the implementation of a new, problem-based science curriculum. The curriculum included applications of LEGO® robotics, a new technology for these teachers. Teachers' responded to structured journaling activities designed to collect information about their…

A gender gap persists in the fields of science, technology, engineering, and mathematics (STEM). Although females constitute half the total workforce in the United States, they make up just greater than a quarter of employees in STEM fields. In recent years, one approach to addressing the gender gap in STEM has involved middle grades science…

The purpose of this study was to compare the levels of pre-service and in-service secondary science teachers' self efficacy beliefs relating to science teaching and to analyze the change of these beliefs according to their demographic characteristics such as gender, the graduate school type, teaching experience and major. The study was conducted…

The purpose of this study was to compare the ability of different instruments, independently developed and traditionally used for measuring science teachers' beliefs in short-term interventions, to longitudinally measure teachers' changing beliefs. We compared the ability of three self-report instruments (Science Teaching Efficacy Belief…

Reforms such as the Next Generation Science Standards (NGSS) call for substantial change in teacher practice such as instruction that is more phenomenon-based, three-dimensional, supportive of student epistemic agency, and coherent from the student perspective. Such change requires ongoing support in the form of aligned curricular materials and…

The purpose of this mixed methods case study was threefold: (a) to describe 7th through 12th grade science teachers' efficacy beliefs, perceptions of support, and concerns about using inquiry-based instruction and examine how they are related to one another, (b) to explore how teachers reporting different levels of concerns demonstrate levels of…

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…

While the United States (U.S.) and Canada share features in their secondary education systems (e.g. proportion of immigrants), these nations have differences (e.g. linguistic ). Given the primacy of Canada over the U.S. vis-à-vis science literacy [as measured by the Programme International for Student Assessment (PISA)], underlying differences in…
