High-voltage plasma arcs from solid-state Tesla coils were used to produce characteristic atomic emissions of various metals. The colored arcs produced were highly visible and vibrant, making for a spectacularly engaging demonstration for groups of varying sizes. The demonstration used an inexpensive solid-state Tesla coil to generate low-current,…

This conceptual paper discusses two frameworks, developed independently by the lead author, that will provide the conceptual foundation for the identification and evaluation of mental computation strategies students demonstrate during an upcoming research project entitled Mental Computation in Year 5. These frameworks will be used by the lead…

This paper reports on concept images of 38 secondary school mathematics prospective teachers, regarding the evenness of numbers. Written assignments, individual interviews, and lesson transcripts uncover salient, erroneous concept images of even numbers as numbers that are two times "something" (i.e., "2i" is an even number),…

In this study we explore how incorporating an arts-based pedagogical approach, specifically, the use of film, art, and music, into a second-year sociological theory course enhances students' overall learning experiences. We report on data collected from a survey given to students enrolled in this course in 2020. Findings reveal that employing this…

This study investigated the effects of a place value intervention with third-grade students with learning disabilities. The intervention added content to a research-based intervention using the concrete-representational-abstract (CRA) sequence. The added content reflected current mathematics standards for third grade. Students' place value…

Design-based learning is considered a powerful way to help students apply and develop understanding of science concepts, but research has shown that the success of this approach is not a given. Examining students' understanding of science concepts in various design-based learning contexts has thus continued to be an important field of research. To…

Research shows that effective and high-quality instructional coaching that targets teacher-child interactions can improve the classroom quality, increase teacher job satisfaction, reduce attrition, and even improve young children's development, such as social emotional development, and literacy skills. Coaches likely develop and sharpen their…

Previous research has shown that students form fragmented understandings about variability even after instruction and that these primitive notions function as obstacles to a robust understanding of variability. To investigate the effect of disruptions to students' primitive notions of variability, we examined undergraduate students' reasoning…

A core challenge for team innovation is the successful translation of creative ideas into innovation through implementation. This study examines the tension between internal and external team resourcing behaviors that account for how teams translate their creative ideas into implemented innovation. Drawing on conservation of resource theory, we…

With the better understanding of human genome and genetic contributions to human complex diseases, more and more clinical genetic tests have been developed for the prevention, diagnosis, and treatment of human diseases. This has raised new challenges to classroom teaching of medical genetics (MG) in medical education of undergraduates, who are…

In mathematics education, researchers often contrast conceptual and procedural teaching approaches, although labels and conceptualizations often vary across studies. Prior research has extensively examined empirical relationships between the two teaching approaches and mathematics achievement. In our study, we aimed to extend this research by…

Learners' efficacy beliefs are an important determinant of their performance and future study in an academic domain, and recent work has highlighted the complexities associated with promoting learners' statistics efficacy. The current study tested the effectiveness of a course-embedded, activity-driven intervention, grounded in principles of…

The aim of this paper is to present a teaching proposal for the theoretical part relating to the first- and second-order linear difference equations with constant coefficients suitable for the first-year students at various types of universities. In contradistinction to the methods often applied (memorization of algorithms without a proper…

Spatial reasoning is one of the most challenging skills to master in the science, technology, engineering, and mathematics (STEM) fields. This article reports the results of a teaching intervention that involved using wooden blocks to enhance the development of spatial reasoning in an undergraduate-level introductory geology course. Wooden blocks…

Young children's meaning-focused skills are foundational for reading comprehension and begin to develop prior to formal reading instruction. In this article, we argue for the importance of supporting meaning-focused skills in early childhood classrooms. We describe authentic, real-life examples of engaging preschool children in activities that…
