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,…

The Vlogs on YouTube have been excellent sources to satisfy craving for mystical and enigmatic distant land detached of our immediate surroundings. Despite the benefits of free world tours in high definition videos, many of the vloggers' framing of the distant land and culture for the purpose of crafting interesting and attractive travelling…

Concept maps help detect misconceptions and provide revision exercises to assess comprehension once a topic has been introduced. A concept map is a schematic drawing used to show the connection among the concepts in propositional form. A concept map is a helpful tool for illustrating the relationships between main concepts and sub-concepts. The…

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),…

This study investigates the effects of a short pedagogical training on university teachers' professional vision and (mis)conceptions concerning teaching and learning, utilizing a mixed-methods approach. Participants' written interpretations of a video-based teaching--learning situation were analyzed and comparisons were made between prospective…

Pedigree problems are typical tasks in school genetics classes. However, they are perceived as difficult and often are not successfully completed. Therefore, the purpose of this study is to determine relevant factors that might have an impact on success in pedigree analysis. Based on previous research, we investigate the influence of the…

Background/purpose: Investigation into the misconceptions of preschool students in mathematics and their differences between the ages of 4-5 and 5-6 years old helps form appropriate developmental mathematics teaching programs. However, although several studies have been conducted examining preschoolers' previous knowledge and misconceptions about…

In this qualitative study, we describe how gender, race, language, and culture cumulatively shape researcher development. Using a collaborative autoethnographic design, we theorize about our experiences as two Black women who conducted their dissertation research in Brazil and Ethiopia. Our data sources include retrospective interviews, journal…

Ongoing evaluation of student progress is a key practice within tiered systems of supports. This study evaluated whether selecting an intervention influenced the number of observations participants requested before determining whether an intervention was working or a change was needed. It was hypothesized that participants who selected the…

Exposure to harmful content, fake news, and hate speech, calls to question whether citizens are 'responsible' when it comes to their online news behavior.

The importance of introducing evolution in primary schools has been highlighted in evolution education research, but few studies have approached the understanding of evolution of prospective teachers who are being prepared to teach at primary school level. The present exploratory study aims to answer three research questions about the ability of…

The COVID-19 pandemic revealed that many countries have failed to provide the general population with the cognitive tools to thoroughly understand and cope with a global health crisis. While scientists and leaders worldwide have struggled to discover ways to contain the spread of the virus, this difficult task has become overwhelming due to the…

Many reviewers of applications for ethical approval of research at universities struggle to understand what is considered ethical conduct in community-based research (CBR). Their difficulty in understanding CBR and the ethics embedded within it is, in part, due to the exclusion of CBR from researchers' mandatory research ethics training. After…

This study aims to evaluate cognitive conflict in constructing mathematical concepts, based on thinking errors. The data were collected through observations of words or sentences, leading to the derivation of qualitative outputs. Furthermore, the results showed that the two selected subjects experienced cognitive conflicts regarding thinking…
