A growing body of literature focusing on undergraduate biology education calls for students to engage in the ways of thinking, feeling, and doing that reflect those in which biologists engage. Such reform efforts suggest that learning is best fostered when students engage in practices, concepts, and scientific reasoning as they endeavor to explain…

The purpose of this proposed quantitative, ex post facto, comparative study with a pretest-posttest design was to assess gains in overall Critical Thinking (CT) skills, and particularly in the Hypothetical-deductive Reasoning (HDR) skills, for pre-health college students tested before and after a Critical Analyses in Science course they attended…

Scientific literacy entails mastery of basic scientific thinking practices. Rather than focus attention exclusively on students' acquisition of science content knowledge, students should be engaged in the practice of science in order to support development of the critical thinking skills essential to scientific work. Previous research (Kuhn et…

This study aimed to enhance students' experimental skills and laboratory techniques in cell and molecular biology. A trifold intervention involving a Gene Screen Worksheet, a Gene Screen Flowchart, and a laboratory manual were used, along with a mixed methods approach to data collection. The trifold intervention was grounded in constructivism,…

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…

The 21st century technology has advanced to become an accessible beacon of education. The physical boundaries of the chemistry laboratory have expanded with the use of innovative virtual lab simulations despite disparate results from previous investigations of student performance comparing virtual lab simulations with traditional laboratory…

Recent reforms in science education call for efforts to engage students in authentic and sustained science practices. In order to engage students in authentic science practices, students need to enact epistemic agency over the processes of inquiry in line with how knowledge is constructed and practiced in the real world. A critical research…

This dissertation examines the thesis that implicit learning plays a role in learning about scientific phenomena, and subsequently, in conceptual change. Decades of research in learning science demonstrate that a primary challenge of science education is overcoming prior, naive knowledge of natural phenomena in order to gain scientific…

This study examined the ways in which elementary science teachers notice, interpret and respond to students' sensemaking resources that students bring to school in the form of science toolkits. The science toolkits are comprised of three sensemaking resources: (1) ideas; (2) out-of-school experiences and funds of knowledge, and (3) youth genre.…

Undergraduate physics laboratory curriculum has undergone significant modification in recent decades in response to research and recommendations from educational and professional organizations and stakeholders. These reforms address multiple issues, such as 1) lack of student agency in experimentation, 2) an incomplete framework for student…

As college biology educators we want students learning how to conduct their own scientific investigations. This means designing laboratory curricula in which students exercise control and responsibility over the knowledge building actions of an investigation--that is, in which they exercise "epistemic agency." Our current understanding…

This qualitative descriptive study aimed to explore how community college students describe their motivations and reasoning when learning about controversial science topics at a southwestern community college. Anti-science attitudes have been increasing globally, but is not fully understood. Two research questions were developed using the theory…

The discipline of data science has gained substantial attention recently. This is mainly attributed to the technological advancement that led to an exponential increase in computing power and has made the generation and recording of enormous amounts of data possible on an everyday basis. It has become crucial for industries to wrangle, curate, and…

Mediocre science achievement and poor STEM graduation rates have prompted educators to reexamine their traditional focus on factual memorization and seek more effective instructional strategies. One such reform-oriented instructional practice is argumentative discourse. Argumentative discourse is student-driven, reasoned argumentation to promote…

Taking a sociocultural perspective, this qualitative case study aims to contribute, investigate, and understand how young Mexican American emergent bilingual learners engage in early science experiences. Furthermore, the study focuses on how the students manifested their knowledge, understanding, and perceptions about science and its…
