As a distinct mode of mathematical representation and communication, geometry diagrams are both signs that represent abstract geometric concepts and visual images that offer graphical-spatial properties. Dynamic geometly environment offers a wide range of tools for its users to create and interact with geometry diagrams. In this paper, I propose a…

LGBTQ history within the US South is rich and diverse though it has remained mostly absent from mainstream and academic narratives around LGBTQ history generally. In recent years, there has been a growing effort to location, preserve, research and make accessible to the community the history of the Queer and Trans South. Despite stereotypes of the…

With fewer people entering agricultural career fields every year, the need for skilled workers in STEM fields continues to grow, which is an issue compounded by the growing demand for food and energy worldwide. An employment pool of skilled applicants who understand agriculture as a whole and comprehend applied concepts of STEM is needed,…

Laboratory activities are a prevalent and essential part of chemistry learning because of their potential to help students develop problem solving abilities, visualize chemistry concepts learned in lecture, and gain practical skills. However, learning in the laboratory environment is not without its challenges. For example, cookbook-style…

Proteins are "magical" workers inside our body, as they accomplish most of the cellular functions. Here we report on a novel approach to teach protein folding and unfolding, using magnets and flexible 3D-printed protein structures. To illustrate this physical process, we used colored circular magnets designed for whiteboards, connected…

This case study is a concentrated look at how online video communications services like Zoom and Microsoft Teams can provide a useful platform for conducting interviews while using the methodological approach of Photovoice. My research aimed to gain insight into the LGBTQAI+ student experience in higher education and support the development of…

This paper explores use of a set of diagrammatic tools for representation and analysis of the moves a teacher makes implementing a mathematical modelling task. The focus here is on identifying what the teacher did so we can subsequently interrogate this, as to the why. Data include pre and post lesson teacher interviews and transcripts of a video…

The most important source of knowledge in primary school teaching is the textbook. This research aimed to determine the differences in graphic illustrations in the contents of natural sciences in a regular textbook and a textbook for children with special educational needs in the Republic of Serbia. As the number of subjects that deal with the…

External representations such as diagrams often appear in teachers' repertoire of pedagogical tools to support students' conceptual learning and problem-solving activities. The study of diagrams and diagrammatic representations has received growing interest from diverse disciplines. Diagrams remain a central feature of science, technology,…

The hundreds chart is a valuable tool for teachers in elementary mathematics classrooms. The present study investigated the effects of spatial configurations of virtual hundreds charts on children's knowledge of base-ten concepts. Kindergarten and first-grade students were assigned to three instructional conditions in which they worked with a…

Preparing students for informed democratic citizenship by learning about contemporary political and social issues requires the ability to critically evaluate online data visualisations. This study examines 25 social studies teachers' perceptions of online data visualisations as informational resources for teaching, and how these perceptions…

Vocabulary development remains an active and robust research area, yet little is known about what students, particularly young students, think during vocabulary learning. A commonly held assumption is that young learners employ few, if any, cognitive and metacognitive strategies when engaged in literacy tasks. Conversely, decades of research…

Visual analytics (VA) technology has become a significant tool for business decision-makers to explore novel insights. One of its key features is analytical reasoning through interactive visualization that users have direct sensemaking in problem-solving processes. Few studies have examined how VA can be applied in business education for improving…

Plant awareness disparity (PAD, formerly plant blindness) is the tendency not to notice plants in one's environment, which leads to the perspective that plants are unimportant. In this paper, we explore how plants and animals are represented in introductory biology textbooks to determine if these texts are contributing to PAD in undergraduate…

Statistical process control (SPC) charts have been widely used in the field of educational measurement. The cumulative sum (CUSUM) is an established SPC method to detect aberrant responses for educational assessments. There are many studies that investigated the performance of CUSUM in different test settings. This paper describes the CUSUM…
