This exploratory study investigated the relationships between time utilisation and the use of visual resources, supported by audiovisual records of the practices of pre-service chemistry teachers applying Teaching-Learning Sequences. The content analysis was based on analytical categories found in the scientific literature. The results showed a…

Animal vocal behaviour represents a certain meaning, which is the explicit expression of animal emotions, needs and communication. Different from human language, animal vocal behaviour is very abstract, and the learning material of animal vocal behaviour is also more difficult to obtain. It is hard for college students to recognize vocal…

According to research findings from all over the world, textbooks play an important role for teachers in the choice of methods, content and educational goals. However, the open textbook market, where the state's influence is limited, results in a significant gap between the state (written) curriculum and actual classroom practice. To understand…

Reading is an integral part of chemistry education. The language of chemistry plays a major role when reading chemistry texts and textbooks. Reading textual and non-textual explanations impact students' understanding of chemistry texts and textbooks. In our review we outline the importance of reading texts and textbooks in chemistry education. We…

This article addresses the nature of student-generated representations that support students' early algebraic reasoning in the realm of generalized arithmetic. We analyzed representations created by students for the following qualities: representations that distinguish the behavior of one operation from another, that support an explanation of a…

Taking as its point of departure a fine-tuned definition of an Internet meme (vis-à-vis a memetic construct), this paper reports the findings of the first diachronic study of memes, the focus being on mask memes on the vast COVID-19 mask memescape evolving in the wake of the pandemic, relative to the changing socio-political situation. The study…

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,…
