Despite multiple calls to action, the United States educational system is not producing enough viable contributors in the areas of science, technology, engineering, and mathematics (STEM). These fields continue to grow, and the STEM workforce continues to expand. However, the pool of citizens prepared to enter these professions is not keeping up…

Project-based learning (PjBL) instruction is an inquiry-based method that is beneficial to student achievement and their exploration of 21st-century learning skills, but there is a gap in the literature about how Grades 6 to 8 teachers feel about PjBL and its implementation. The research problem was science teachers in the United States were not…

The problem in this study was that despite encouragement from administrators, kindergarten through Grade 8 teachers struggled to use project-based learning (PBL) in a local school in the Association of Independent Maryland and DC Schools (AIMS). Rooted in Kilpatrick's progressive philosophy of education and Piaget's theory of constructivism, this…

School districts choose programs based on limited data, word of mouth, or cost-effectiveness. STEM-based schools often choose project-based learning (PBL) programs to deliver curricula through limited research and word of mouth effectiveness. This study evaluated one PBL program implementation in the context of a suburban Texas middle school by…

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…

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…

Functioning in a world beyond school requires more sophisticated understanding of both content knowledge and knowledge production across the disciplines (Lee & Spratley, 2010; Shanahan & Shanahan, 2008), as well as how to access, interpret, and share information in print and online environments (Afflerbach & Cho, 2009; Coiro &…

Project-based learning (PBL) is an instructional method that has grown in popularity across all grade levels and subject areas, in both K-12 schools and higher education institutions. PBL embraces the integration of curriculum across subjects, the engagement of home and community in school learning, and the involvement of students in cooperative…

The purpose of this quantitative study was to compare and evaluate two types of vocabulary interventions using grade 9 physics vocabulary terms using two lists of 10 words. A quasi-experimental crossover research design was used to compare the two interventions, presented during two separate sessions, 1) active, multimedia that includes the…

The study examined the impact of Project-Based Learning on reading and mathematics achievement of 7th and 8th grade students. Project-based learning deviates from the customary school practices and is an innovative strategy used in the curriculum to engage students in solving authentic problems for deeper learning experiences. The association…

Understanding of visual representations is a pivotal skill necessary in science. These visual, verbal, and numeric representations are the crux of science discourses "by scientists, with students and the general public" (Pauwels, 2006, p.viii). Those who lack the understanding of these representations see it as a foreign language, one…

Studies have shown an association between argumentative discourse in science class, better understanding of science concepts, and improved academic performance. However, there is lack of research on how argumentation can increase student motivation. This mixed methods concurrent nested study uses Bandura's construct of motivation and concepts of…

The primary purpose of this study was to determine significant relationships between growth in student learning in mathematics and characteristics of effective teacher professional development and teacher demographics. The goal was to determine whether certain characteristics of professional development, as measured by the Characteristics of…

This mixed methods study was designed to compare the effect of using an inquiry teaching methodology and a more traditional teaching methodology on the learning gains of students who were taught a five-week conceptual change unit on density. Seventh graders (N = 479) were assigned to five teachers who taught the same unit on density using either a…

Many middle school students are not achieving the Adequate Yearly Progress (AYP) at individual schools in North Carolina. A consequence of continual failure to reach AYP goals is the withdrawal of Title 1 funding. Since federal funds are an integral part of nearly half of the public schools in North Carolina, it is imperative that students improve…
