The article describes a mini-escape game with an environmental theme. The game was prepared using LearningApps and Google Slides. The mini-escape game comprised 7 subactivities: Crossword, Matching Pairs, Multiple-Choice Quiz, Cloze Test, Word Grid, Group Assignment, and Freetext Input. Through completion of these subactivities, students gradually…

When thinking about Olympic winter sports and watching events on television, people mostly focus on events where the chances of success are high for fellow-countrymen. For example, in the Netherlands speed skating is considered the main winter sports event. But with Kimberley Bos there is now also a Dutch medal candidate for the Winter Olympics…

Electrification by rubbing different materials is a well-known phenomenon with a history that began more than five centuries B.C. ago. However, simple experiments can lead to contradictory or inconsistent results, and the history of this phenomena is plagued with non-intuitive results. For example, triboelectric charging by rubbing identical…

Recent reports indicate that employers are increasingly interested in hiring individuals that can think critically and are able to solve complex problems. Further, the ability to apply knowledge learned during college to real-world settings is a major sought-after skill. Overall, these findings emphasize the importance of teaching our students to…

Ratios and proportions are new topics in the primary curriculum. Previous research shows that Year Five pupils have difficulty in learning ratio and proportion. This study aims to identify the conceptions of ratio and proportion of seven year five pupils. It is based on radical constructivism using qualitative case study. Data was collected…

In this article, we leverage ideas from the theory of coevolutionary computation to analyze interactions of students with problems. We introduce the idea of "informatively" easy or hard concepts. Our approach is different from more traditional analyses of problem difficulty such as item analysis in the sense that we consider Pareto…

We investigated understanding of the linear independence concept based on the type and nature of connections displayed in seven non-mathematics majors' interview responses to a set of open-ended questions. Through a qualitative analysis, we identified six categories of frequently displayed connections. There were also recognizable differences in…

Within the Threshold Concepts Framework, 'postliminal variation' has been defined as the variation in the point and state of exit into a new conceptual space, and the epistemological and ontological terrain encountered from that point onwards. However, in the extensive published literature on threshold concepts, we find many cases in which its…

In this article, I argue that the common practice across many school mathematics curricula of using a variety of different representations of number may diminish the coherence of mathematics for students. Instead, I advocate prioritising a single representation of number (the number line) and applying this repeatedly across diverse content areas.…

The laser pointer has been widely used to demonstrate some simple optics phenomena, like reflection, refraction, total reflection, and diffraction. However, the rays of laser light cannot be seen in the air because the scattered light is too weak. Many physics teachers use milk or smoke to visualize rays of laser light in physics labs, but it is…

This article aims at examining the relationship between students' expressed notions of infinity and strategies used to compare the cardinalities of infinite sets. The notions of infinity were classified into two categorizations of potential and actual infinity, and the strategies were classified as part-whole, single infinity, incomparability and…

The paper is the result of extensive research carried out among Czech students and focuses on a conception of infinity. The questionnaire survey was taken by 861 students ranging from grades 7 to 13. The aim of the research was to describe the development of students' conceptions of infinity. These conceptions are built on the intuitive phenomenon…

This study describes the integration of citizenship education into the K to 12 Junior High School Economics curriculum in the Philippines. Content analysis of the 2016 Curriculum Guide Learning Competencies (CGLCs) and 2020 Most Essential Learning Competencies (MELCs) for Social Studies was conducted to determine the alignment of the Economics…

The dialogues, debates, and even arguments resulting from misunderstanding, misinterpretation, and mishandling of programs and people associated with the term "giftedness" are longstanding. Despite many years of efforts to assuage concerns of equity and need--many of which are legitimized by research evidence, the terminology continues…

Preparing engineering undergraduate students for the workforce is a goal of engineering programs. Engineering educators arguably provide students with conceptual understanding of engineering fundamentals; however, few studies focus on how knowledge of these concepts transitions into the engineering field. Concept inventories have been used in…
