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 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…

My problem of practice is that my learners were not learning and growing to their fullest potential in both content and necessary future ready skills -- 21st century and process skills to prepare them for postsecondary life outside of my classroom. I teach many high school learners with exceptionalities. I sought to alter my instruction and ensure…

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…

This dissertation asks how to improve science education and science communication, and suggests that digital storytelling techniques can be used to better engage learners in the process of knowledge making. Digital storytelling refers to both the use of high-quality digital media content as learning materials, and also to the use of social…

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…

Four of the eight Engineering Standards in the Next Generation Science Standards (NGSS, 2013) focus on authentic science communication: "asking questions (science) and defining problems (engineering), analyzing and interpreting data, constructing explanations (for science) and designing solutions (for engineering), engaging in argument from…

The economy of tomorrow is uncertain, so students today need to be prepared for the known and unknown careers that lie ahead. Currently, not all students are expected to have equal career opportunities based on evidence from dropout and testing data (Brown & Brown, 2007; Kirsch, Braun, Yamamoto, & Sum, 2007), so educators should consider…

Recent calls in education have emphasized the critical need for curricula in the sciences to support student development of the general and disciplinary-specific practices that are relevant to modern scientific research and careers, as well as foundational scientific knowledge that reflects recent advances. In this regard, the life sciences,…

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…

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…

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…

The development of scientifically literate citizens begins in the elementary school. Yet elementary school teachers are ill prepared to teach science (Trygstad, Smith, Banilower, Nelson, & Horizon Research, Inc., 2013). The research base on teacher preparation finds that programs designed to prepare elementary teachers are inadequate in…

The purpose of this qualitative study was to explore the use of 3-D printed models as an instructional tool in a middle school science classroom for students with visual impairments and compare their use to traditional tactile graphics for aiding conceptual understanding of geoscience concepts. Specifically, this study examined if the students'…
