To maintain its dominance as a leader in STEM, as well as to disrupt persistent economic and social inequalities, the United States must invest in Black and Hispanic students who are among the largest subgroups who have been historically underrepresented in STEM spaces. Research has shown that science self-efficacy facilitates students' interest,…

This quantitative study was designed to investigate if relationships existed between elementary science teachers' self-efficacy toward science teaching, schedule structure (self-contained or departmentalized), experience level of teachers, amount of time dedicated to science instruction, and student achievement on a standardized science…

This study was conducted in response to the growing concern about the lack of U.S. students majoring in STEM fields and pursuing STEM careers (NSF, 2013). In order for the U.S. to compete in a global economy that is increasingly technologically-based, a skilled STEM workforce is a necessity (National Academies, 2010). Understanding the factors…

A teacher's sense of self-efficacy may have significant influence on the pedagogical decisions in the classroom. An elementary school teacher's sense of self-efficacy in teaching science may negatively influence student achievement in science. Negative beliefs concerning science or the ability to teach and promote student learning in science may…

The purpose of this study was to examine the relation between middle school teachers' personal teaching efficacy and their students' academic efficacy for science and inquiry science. Teachers can create classroom environments that promote the development of students' science self-efficacy (Britner & Pajares, 2006). Teachers who are efficacious…

This study examined the relationships between teacher leadership, science teacher self-efficacy, and fifth-grade science student achievement in diverse schools in a San Antonio, Texas, metropolitan school district. Teachers completed a modified version of the "Leadership Behavior Description Question" (LBDQ) Form XII by Stogdill (1969),…

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 critical psychology perspective (Prilleltensky and Nelson, 2002) advocates for research that focuses on social change, the mutual participation of community stakeholders, and the empowerment of those served. The current study applies this critical psychology perspective to career education programming in a multiculturally diverse rural high…

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…

The nation's generation of "Baby Boomers" is now the grandparents of a new generation of students known as "Gen Y" and "Gen Z," respectively. "Gen X," parents of our current students, have the enormous task of raising their children as "digital natives" in a technological-savvy world. The idea of…

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…

My dissertation is a pre-mid-post-test, quantitative research design, including surveys and written assessments, to answer these research questions: 1. How do students' science mindset vary over time when engaged in science inquiry activities? Is there a difference between male and female students? 2. Is there a relationship between 7th grade…

Self-efficacy can determine how hard a student works, if they will persevere in the face of obstacles or succeed academically (Britner & Pajares, 2006). It has been suggested that practices in an inquiry-based science class can provide positive experiences needed to increase self-efficacy of middle school students (Britner & Pajares,…
