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…

Students entering high school often bring misconceptions about the nature of science and experimentation with them from middle school. Many also bring a belief that they are not a "science kid" and, therefore, cannot be a strong student in Biology. This belief can lead to a lack of self-efficacy and of student agency in the classroom.…

This study investigated evidence of how students' mental models of fundamental kinematic relations evolved (i.e., developed cognitively over time) as observed during an introductory course in calculus-based classical mechanics. The core of the curriculum is based on a claim known as Galileo's principle of relativity. The course material comprised…

The purpose of this study was to investigate whether the course, Scientific Inquiry, significantly increased the self-efficacy beliefs of its students. According to Bandura (1977), an increase in self-efficacy could increase the likelihood that teachers implement scientific inquiry in their classrooms. I explored self-efficacy in an effort to…

The purpose of this mixed-method action research study was to improve Black students' performance in my sixth-grade science class by improving their ability to use the claim, evidence, and reasoning (CER) framework. Using criterion-based convenient sampling, I enlisted 17 Black participants, all of whom were underperforming in my science class at…

Nature of Scientific Knowledge (NOSK) and Nature of Scientific Inquiry (NOSI) are important components of scientific literacy and important educational objectives in science education. Recent literature theorizes that understanding both NOSK and NOSI increases students' understanding of science content knowledge. However, this assumption has yet…

Integrating decision-making learning goals within science classrooms has been increasingly common for science educators and researchers to help develop students' science literacy skills. These learning goals include understanding and applying scientific information as well as recognizing tradeoffs amongst multiple perspectives when decision-making…

Visual-spatial literacy is an essential component to developing STEM literacy, which is a primary focus of the three-dimensional Next Generation Science Standards (NGSS) framework for science education. Because scientific data is frequently communicated through visual representations, it is important for members of the current science and…

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…

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 investigation of Science, Technology, Engineering, and Mathematics (STEM) and the quality of education within and between the four disciplines continues to be a topic of concern throughout the United States. Employers, policymakers and educators have recognized a need for a stronger focus on the quality of STEM education in schools (Becker…

There is a call in science education for students to be in the business of "doing science," rather than "doing the lesson" (Jimenez-Aleixandre et al., 2000). Developing explanatory models is one important strategy for sensemaking in science. Teachers' knowledge plays a critical role in how classroom interactions are framed and…

Science education at the postsecondary level is essential to building a foundation for increasing support, participation, and interest in STEM occupations and careers. This current study uses a phenomenological approach to explore the lived experiences and perspectives of eight post-secondary science majors while enrolled in a university 200-level…

The study consisted of three articles. Article one aimed to determine if there were any significant difference in science graduate students' (SGSs') conceptions of the "consensus tenets" of the nature of science (NOS) with respect to demographic factors -- the SGSs' academic and research characteristics. The participants were SGSs from…
