An important element to doing mathematics and developing conceptual understanding in mathematics is creating and making sense of visual representations. Developing mathematical understanding happens when students invent (or reinvent) strategies and think deeply about why a strategy works. Although societal and political pressures may say otherwise…

With their increasing popularity, there is a need for more research clarifying the potential strengths and weaknesses of the comic format for education. The panelled comic format may be particularly effective for educating adults on the scientific aspects of processes (sequences of events, occurring over time, in a series of discrete steps). We…

As a widely applied theory that has found success across many fields, density functional theory (DFT) is largely taught. Typically, the most effective way to convey DFT concepts is through illustrative examples that are currently lacking in available resources. In this work, we demonstrate total energy calculations for H[subscript 2] using…

Knowing how children become oriented to imaginary play can help educators in centres better support development. But how this begins in the first years of life is not well understood. How toddlers transform through their imagination concrete objects (such as play accessories, figurines, and books) to become props in play (placeholders and pivots)…

The use of visual materials in education is a traditional way of teaching. Images are one of the many kinds of teaching methods used by teachers in order to enrich the teaching of their lessons and to revitalise the way they teach. The utilisation of illustrative material when teaching depends on many factors. One of these is the instruction and…

This study is based on the bibliometrics analysis of research publications that focus on highlighting the argumentation on mathematics education. The main objective of this study is to analyze the distribution of research results, the main journals for publication, and the most productive authors, the pattern of authorship and the pattern of…

A Spreadsheet Excel application for chromatographic peak characterization is described in this article. Data are exported from HPLC specific program to an Excel file with macros to perform basic calculations as retention time, height, and area of the peaks. From these values, peak resolution, asymmetry, or theoretical plates are calculated and…

The ability to reason with representations is pivotal for successful learning in Organic Chemistry and is closely linked to representational competence. Given the visual nature of this discipline, this comprises competency in extracting and processing relevant visual information. With regard to the resonance concept, proficiency in identifying…

The generative learning strategy of learning by drawing has received increased attention in recent years. Although this strategy is regularly used by educators, the literature suggests that the effectiveness of the method depends on several factors. In this review, we highlight recent research trends and methodological progress within the field.…

Energy is a crosscutting concept in science, but college students often perceive a mismatch between how their biology and chemistry courses discuss the topic. The challenge of reconciling these disciplinary differences can promote faulty reasoning--for example, biology students often develop the incorrect idea that breaking bonds is exothermic and…

Data visualizations play a crucial role in communicating patterns in quantitative data, making data visualization literacy a key target of STEM education. However, it is currently unclear to what degree different assessments of data visualization literacy measure the same underlying constructs. Here, we administered two widely used graph…

Student performance, disciplinary innovation and teaching methodology occupy the main concerns of educational research. Therefore, there is a greater interest in gamification strategies, where digital tools facilitate the development of competitive activities and strengthening of learning. One example of this idea is the use of video games created…

Teachers are increasingly using augmented reality (AR) to develop students' higher-order thinking (HOT). As past studies showed mixed results, our "random effects meta-analysis" of 21 effect sizes from 17 studies of 1256 participants determined the overall effect of AR on HOT and accounted for differences across studies via moderator…

Research on the effectivity of PowerPoint presentations as an adjunct to theoretical and practical content during university lectures has garnered significant yet inconclusive findings. Specifically, how multimodal academic content should be organised to aid communication remains unclear. Legitimation Code Theory (LCT) introduces the concept of…

First-year college students experience difficulties in understanding the concepts of derivatives and integrals. At the postsecondary level, the use of static visualization and other traditional instruction delivery methods often are unable to meet students' needs in calculus. This problem is current and essential in the field of education and…
