This thesis identifies and explains the gaps in prior and current applications of representational competence construct in chemistry. Representational competence (RC) describes a set of skills that chemistry researchers Kozma and Russell observed experts demonstrate when engaging with disciplinary representations (Kozma & Russell, 1997; Kozma…

Spatial skills, the set of cognitive skills that are responsible for our understanding of objects in real and imagined spaces, have been identified as a potential gate-keeper for STEM success. Because of the recent emphasis on improving education to prepare for the increasing demand for workers in STEM fields, there is a rising interest in…

Physics education researchers have called for a shift from traditional laboratory (lab) instruction to labs that focus on the development of experimental skills. Although research has demonstrated the efficacy of such reformed labs, much work remains to determine what these labs can and should teach students and how best to achieve these goals.…

The study aimed to investigate how the knowledge, understanding and skills of secondary science teachers in SC relate to their capacity to deliberately integrate World Class Skills (WCS) into their science classroom instruction through effective planning and pedagogical choices. The study employs the Partnership for 21 Century Learning framework…

The complexity of science visual literacy education calls for a better understanding of elementary teacher visual literacy practices. Teachers play a key role in developing students' visual fluency through the visual literacy skills they develop in their pedagogical practices. Addressing these gaps in the research, this dissertation focused on the…

This dissertation examines students' social-emotional experience with knowledge building pedagogy from the lenses of grit and growth mindset. The goal of this dissertation is to understand how interest, perseverance of effort and growth mindset oriented feedback engage students social emotionally in knowledge building to sustain and deepen their…

This qualitative action research study examines how middle and high school STEM teachers create and implement lessons that connect concepts to the real-world and develop student metacognition. The researcher collected data through interviews, focus groups, document analysis, and survey questions. Participants from vocational, private, and…

The problem addressed in this study was high school science teachers' lack of understanding of science, technology, engineering, and mathematics (STEM) and clarity for the integration of Next Generation Science Standards (NGSS) approaches to align standards in STEM with high school science education. The purpose of this qualitative case study was…

The purpose of this three-article dissertation was to expand knowledge and theory regarding digital tool use in biology laboratory courses, such as microbiology, which requires specific laboratory skill development through the perception of instructors and students. Article 1 establishes the broad digital literacy and fluency problem in education…

Introductory physics lab instruction is undergoing a transformation, with increasing emphasis on developing experimentation and critical thinking skills. These changes present a need for standardized assessment instruments to determine the degree to which students develop these skills through instructional labs. In the first part of this thesis,…

Adaptive Learning, as a new online learning environment, intends to individualize the learning experience for each individual learner. Adaptive Learning suffers many shortcomings, as the date of the publication of this dissertation, however, it is considered the next generation of the learning environment for at least the next twenty years;…

The purpose of this study was twofold: (1) to determine the effectiveness of virtual laboratories relative to traditional or blended laboratories in the attainment of conceptual knowledge and skill in microscopy; and (2) to explore how such technologies are integrated in real world classrooms. Four sections of a non-major's introductory biology…

The research presented in chapters 2, 3, and 4 in this dissertation uses a sociocultural and sociohistorical lens, particularly around power, authority of knowledge and identity formation, to investigate the complexity of engaging in, supporting, and evaluating high-quality argumentation within a college biochemistry inquiry-oriented classroom.…

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…

The recent decades have seen an increased focus on improving early science education. Goals include helping young children learn about pertinent concepts in science, and fostering early scientific reasoning and inquiry skills (e.g., NRC 2007, 2012, 2015). However, there is still much to learn about what constitutes appropriate frameworks that…
