This Doctor of Arts dissertation addresses the use of drawing as a tool to facilitate life science education and research. The literature review addresses frameworks of drawing-to-learn and Professional Vision which guided the design and implementation of the research and education experiences. A result of this dissertation work is a manuscript…

This three-paper dissertation systematically investigates the methodology issues related to using observational systems to observe, analyze, and interpret teachers' reformed teaching practices within the K-12 classroom context. Each paper contributes a distinct perspective to evaluate instructional practices accurately, consistently, and…

The purpose of this applied research study was to improve the use of three-dimensional pedagogy in science classes in chronically low-performing schools. The need to build teacher capacity became evident after the state adopted more rigorous science standards revealing deficits in teachers' pedagogical content knowledge. This study utilized two…

In this dissertation I explore characteristics which influence the implementation of evidence-based instructional practices of six post-secondary chemistry instructors in Colorado who report current use of these practices. The purpose of this study was to identify these characteristics to recognize areas of focus for future professional…

The study addressed the gap in fifth-grade science proficiency between English language learners (ELLs) enrolled in two different science programs in a large school district in the Southeast United States. The Inspire program was implemented in 125 schools, while a combination of Inspire and Promoting Science among English Language Learners…

The purpose of this three study dissertation is to investigate why students are enrolled in introductory physics courses experience difficulties in being successful; one possible source of their difficulties is related to their epistemology. In order to investigate students' epistemologies about mathematics and physics, students were observed…

As we approach the second quarter of the twenty-first century, one may predict that the environment will be among the dominant themes in the political and educational discourse. Over the past three decades, particular perspectives regarding the environment have begun to emerge: (i) realization by human beings that we not only live on earth and use…

Most recently, there has been a noticeable rise in the push for use of technology in the classroom. The advancement in digital science has increased greatly the capacity to explore animations, models, and interesting apps. that should substantially enhance science cognition. At the same time, there is a great need to increase collaboration in the…

With all of the research devoted to the use and effectiveness of constructivist learning principles in high school science classes, it is somewhat surprising to find that there is very little research devoted to constructivism's use in international settings. The problem that this lack of research poses is that classrooms are increasingly diverse…

Teaching students to construct scientific understanding is complex. Teachers who develop noticing skills can attend and respond to students' science ideas to move understanding forward. Traditional professional development (PD) approaches limit teachers' opportunities to develop noticing skills. This study examined what aspects of a collaborative…

Empirical evidence from the National Education Inspectorate suggested that teachers at the primary school in this study in an island country in the Caribbean have inadequate science content knowledge. Students' average performance on the science Grade Six Achievement Test (GSAT) has been below 40% for the last 5 years. The purpose of this bounded…

This multiple case-study investigated how high school biology teachers used modern learning technologies (probes, interactive simulations and animations, animated videos) in their classrooms and why they used the learning technologies. Another objective of the study was to assess whether the use of learning technologies alleviated misconceptions…

Current education reform in both the United States and China promotes a reformed inquiry-based approach based on the constructivist learning theory. This study contributes to the research literature by exploring the relationship between reformed science teaching and students' creativity. Chinese education is often criticized for a lack of…

The purpose of this study was to explain middle school teachers' decisions for planning a science unit of instruction (reflection on action) and their decisions when enacting this planned unit (reflection in action) using the new teacher professional knowledge and skill (TPK&S) model as a guiding framework. In addition, this study specifically…

Recent educational studies have shown increasing lack of interest and participation of youth (ages 10-14 years old) in various STEM (Science, Technology, Engineering and Mathematics) fields in the U.S. The decline in the number of youth choosing to study STEM fields in higher education and the resulting lack of STEM professionals in the society…
