To fully appreciate genetics, one must understand the link between genotype (DNA sequence) and phenotype (observable characteristics). Advances in high-throughput genomic sequencing technologies and applications, so-called "-omics," have made genetic sequencing readily available across fields in biology from applications in…

Though argumentation is a key component of scientific knowledge construction practices, it rarely occurs in classrooms worldwide. Moreover, related literature in the context of genetics and evolution learning primarily addresses them separately. In contrast, this paper is part of broader research on genetics and evolution instruction taught…

Recent calls to reform undergraduate biology education, including Vision and Change in Undergraduate Biology Education, have led biology departments to examine their curriculum to determine the extent to which it aligns with Vision and Change content and competency recommendations. The recently released BioSkills Guide translates the broad Vision…

Research in computer-based learning environments has long recognized the vital role of adaptivity in promoting effective, individualized learning among students. Adaptive scaffolding capabilities are particularly important in open-ended learning environments, which provide students with opportunities for solving authentic and complex problems, and…

We introduce a novel approach to visualizing temporal clickstream behaviour in the context of a degree-satisfying online course, "Habitable Worlds," offered through Arizona State University. The current practice for visualizing behaviour within a digital learning environment is to generate plots based on hand-engineered or coded features…

In the present study, complex dynamic systems theory and interpersonal theory are combined to describe the teacher-student interactions of two teachers with different interpersonal styles. The aim was to show and explain the added value of looking at different steps in the analysis of behavioral time-series data (i.e., observations of teacher and…

In an effort to broaden the selection of research opportunities available to a student registered in a one-semester, upper-level independent study course at a primarily undergraduate institution (PUI), a highly motivated student was asked to select, evaluate, and modify a standard operating procedure (SOP). The student gained valuable experience…

Hands-on learning is a highly effective teaching method for topics in STEM disciplines. Unfortunately, environmental science teachers sometimes lack the tools to engage their students in hands-on experimentation in real-world research outside of the classroom. Partnerships between science professionals and teachers can help address this disparity,…

The purpose of this case study is to delve into the complexities of the early development of preservice chemistry teachers' science teaching orientations, knowledge of learners, knowledge of instructional strategies, and knowledge of assessment during a two-semester intervention designed to enhance their pedagogical content knowledge (PCK) for…

This study explored 6th grade students reading of science text on the iPad to better understand how students with varying strengths of comprehending text and current academic abilities interpret text on their iPads. Our study sample compared three students with strong reading scores based on informal reading inventories, standardized tests, and…

This study aims to assess whether the handling of concrete ball-and-stick molecular models promotes translation between diagrammatic representations and a concrete model (or vice versa) and the coordination of the different types of structural representations of a given molecular structure. Forty-one Algerian undergraduate students were requested…

This is an interpretive case study to examine the teaching of an experienced science faculty who had a strong interest in teaching undergraduate and graduate science courses and nature of science specifically. It was interested in how he transformed knowledge from his experience as a scientist and his ideas about nature of science into forms…

Teaching outdoors has been established as an important pedagogical strategy; however, science classes rarely take place outside. Previous research has identified characteristics of teachers who have integrated out-of-classroom opportunities into their teaching repertoire; yet little is understood as to why teachers make these different pedagogical…

This study explored third-grade elementary students' conceptions of nature of science (NOS) over the course of an entire school year as they participated in explicit-reflective science instruction. The "Views of" NOS-D (VNOS-D) was administered pre instruction, during mid-school year, and at the end of the school year to track…

This dissertation used a combination of case study and phenomenological research methods to investigate how individual teachers of middle school science in the Alabama Math, Science, and Technology Initiative (AMSTI) program sustain their use of inquiry-based methods of teaching and learning. While the overall context for the cases was the AMSTI…
