Project-Based Learning (PBL) is a teaching method in which students learn by actively engaging in real-world, personally meaningful projects that allow conceptual transformation to occur within the educational process while fostering intellectual curiosity in a supportive learning environment. PBL supports students developing deep content…

Although many undergraduates begin college as STEM majors, attrition rates from the field are high and numerous reports suggest that evidence-based teaching methods are critical for retention. Despite educators' research and near consensus that active learning is more effective than lecture, there are many types of active learning and the…

This dissertation focuses on three manuscripts all related to bolstering science achievement through recommendations from the National Research Council (NRC) regarding the teaching and learning of science. The manuscripts address meeting the NRC's call to incorporate curriculum and assessment that lead to more in-depth knowledge that can be…

This quantitative, nonexperimental research study focused on discovering the impact of inquiry-based instruction on the science achievement of rural Georgia fifth-grade students as measured by the Georgia Milestones Assessment System (GMAS), a criterion referenced test. Inquiry-based instruction is a teaching method that combines the natural…

This study examines the opportunities presented to high school chemistry students through argument driven inquiry (ADI) and how these opportunities led to changes in student understanding. Lesson plans and videos were analyzed to determine how much time students spent arguing from evidence including constructing and argument board, discussing with…

The effect of class size on student learning has numerous policy implications and has been a major subject of conversation and research for decades. Despite this, few studies have been done on class size in the context of university settings or physics courses. This dissertation helps address that gap in the literature by quantitatively analyzing…

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…

It has been well-establishing in the field of educational research that traditional educational methods such as passive lectures and labs where students follow pre-designed procedures to verify information already told to them are not effective for promoting meaningful and lasting conceptual understanding. Alongside this knowledge have come a…

This three-paper dissertation addresses the experience and the implementation of evidence-based learning practices in science, technology, engineering, and mathematics (STEM)/biology education. Study 1 explored instructional strategies and student perceptions and preferences for various teaching practices in graduate and undergraduate classrooms…

Research in the past ten years has shown that there has been a lack of professionals to fill the jobs available in science. One possible reason for the lack of participation in science fields lies in students' beliefs in their ability to do science, or science self-efficacy, which is linked to interest and achievement. Their perceptions of science…

Participation in the science workforce is low, and this can be partially attributed to low retention rates of undergraduate students who initially declare a science major. Low retention rates are further exacerbated for under-represented minority (URM) and first-generation (FG) college students pursuing science, and the existence of achievement…

The purpose of this study explored alternative teaching methods to improve student outcomes in the classroom. The researcher investigated the effects of the active learning strategies, Process Oriented Guided Inquiry learning and Peer Instruction on student achievement, conceptual understanding, and students' self-efficacy in an honors biology…

This study is composed of several projects in the field of physics education research. First, investigations into flipped physics classrooms at the senior and graduate level show that students uniformly agree that the active learning techniques (peer instruction, group problem solving, etc.) were beneficial to their learning regardless of their…

The use of technologies in and outside classrooms has attracted young adolescents who must be prepared to embrace the opportunities and face new challenges in the 21st century. Educational systems across the US continue to gravitate toward new technologies such as digital cameras, interactive-boards, and software that have been shown to enhance…

"Place-based education" refers to pedagogy that connects student learning with the local environment and students' lives. Educators' preoccupation with standardized test scores have increased the disconnect between formal education and student's life experiences. Schools have developed systems of learning in isolated subjects through…
