This dissertation investigates the complexities associated with developing expertise in physics problem-solving and the methods for measuring and assessing the skills involved. Problem-solving skills are critical in today's rapidly changing world, and thus, it is important to emphasize them in education. However, lacking precise methods for…

As schools continue to focus on outcome-based instructional practices, less emphasis is placed on the creativity and reasoning necessary for students to become effective critical thinkers. As a result, students struggle to demonstrate creative problem-solving skills in the classroom. This study examines how the facilitation of an instructional…

The purpose of this action research study was to explore the impact of problem-based learning on science instruction in my eighth-grade college preparatory classroom. Constructivism was the framework for this study. Problem-based learning is based on constructivist principles, and it served as the instructional model for this study. PBL can foster…

I have created a general workflow that describes how students reason through non-trivial organic predict-the-product problems. This was accomplished through an iterative process that combined the experiences of instructors with holistic impressions of think-aloud interviews, incorporating feedback from both undergraduate focus groups and graduate…

Organic Chemistry is considered by many to be the quintessential "weeder course", widely identified in the premed and STEM persistence literature as a gatekeeper to students interested in STEM or health fields (Barr, Gonzalez, & Wanat, 2008; Lovecchio & Dundes, 2002). There has therefore been considerable interest in determining…

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 study examined laboratory experiments and traditional lecturing as an introductory teaching method in physics. In this participatory action research study, a qualitative and quantitative method were used to examine the level of achievement and the levels of engagement of high school students in introductory physics. The qualitative data was…

This study tested the hypothesis that exploratory learning, with and without analogous problems, would improve students' ability to make connections between conceptually-related topics. In this randomized experiment, undergraduates in introductory physics (N = 171) studied a new topic under three different instructional conditions. Order and type…

Over the last two decades, students in Singapore consistently scored above students from other nations on the Trends in International Mathematics and Science Study (TIMSS; Provasnik et al., 2012). In contrast, students in the United States have not performed as well on international and national mathematics assessments and students with…

This study investigated the knowledge and skills that biology students may need to help them understand statistics/mathematics as it applies to genetics. The data are based on analyses of current representative genetics texts, practicing genetics professors' perspectives, and more directly, students' perceptions of, and performance in, doing…

Recent trends indicate a significant decline in the number of students graduating from Science, Technology, Engineering and Math (STEM) programs in the US. The under-representation of students of color, females and low income students in STEM programs has also been documented. Design Based Science (DBS) instruction has been suggested to improve…

This research was designed to study the effect of a professional development program in place-based science education on teacher and student learning in rural elementary schools in Thailand's northern Lampang province. Based on the results of a pilot study conducted in 2008 at one school, which was then followed by a needs assessment conducted…

This study sought to compare a data-rich learning (DRL) environment that utilized online data as a tool for teaching about renewable energy technologies (RET) to a lecture-based learning environment to determine the impact of the learning environment on students' knowledge of Science, Technology, Engineering, and Math (STEM) concepts related…

Background: The current mode of stoichiometry instruction employs a passive pedagogy that consists of students reading, listening, watching, and memorizing disembodied facts, procedures, and principles in preparation for future application. But chemistry students are often subsequently unable to apply this stoichiometry knowledge in equilibrium…

The significant increase of English Language Learners (ELLs) in the United States raises complex questions about how to provide these students with access to high quality education that can improve both their content knowledge of school subjects and their English proficiency, particularly their academic English proficiency. The development of…
