As phenomena, time, and history, particularly the nature of the two and how to tell them apart, are not easily defined. In the tradition of historical consciousness, time, and the human understanding of the nature of time are defined as a part of a historical consciousness, where this may more or less evolved. In this study, students aged 11 were…

Environmental components, including soil, water, air, and biodiversity, are vital for maintaining the balance of the ecosystem. However, environmental pollution is one of the most significant threats to these balances. With environmental pollution, the balance of ecosystems is disrupted, and the food chain is negatively affected. The food chain,…

Recently, the importance of statistical literacy has been stressed, and three central concepts in statistical literacy are the measures of central tendency: mean, median, and mode. This study explores aspects of statistical literacy expressed by 12-13-year-old students, focusing on mean, median, and mode. Their responses were analysed using a…

The current study examined how prospective first- and second-grade mathematics teachers define the polygon diagonals concept, how they reconstruct their definition during and following an intervention, and how their concept images develop over time. Twenty-three prospective teachers participated in the study, during which they were asked to…

The paper presents findings from a study that examined, through the lens of the Image Having layer of the Pirie-Kieren model, the qualitative characteristics of the images that different children formed when engaging with eight, novel partitive quotient tasks. The Image Having layer is the first point of abstraction within the Pirie-Kieren model.…

Unlike in other countries, heredity and genetics appear first in Spanish science standards in secondary levels. However, some researchers have suggested the need of progressively introducing some basic genetic ideas already from primary education levels. In this context of no formal instruction in early stages, the objectives of our work were to…

In this research, we explore the use of storybooks as an educational tool for fostering a meaningful understanding of artificial intelligence (AI) technologies for children and consider how AI should be depicted in storybook narratives to achieve this. We present guidelines for the depiction of AI in narratives for four- to six-year-old children…

Purpose: This paper aims to introduce a novel AI learning progression for upper-elementary students and aligns assessment items across levels of each construct to gather evidence of understanding. It also validates this quantitative measure by examining these items as two subscales for psychometric properties using the Rasch model.…

Time is an important but complex area of learning for students in the primary years. This study sought to develop a tool which would provide a clear picture of students' understanding of what constitutes time and how time is related to clock and calendar use. Four major components of time, Awareness of time, Succession, Duration, and Measurement…

Scientific literacy is the primary goal of elementary science education. Scientific literacy requires an overall understanding of what science is, and how and why scientific knowledge is developed. The normal assumption is that as students progress in school, they learn more. One would expect students to become more scientifically literate as they…

The aim of this study is to examine the concept images of mathematics educators and pre-service elementary mathematics teachers regarding the relationships between the concepts of slope, rate of change and derivative. Four mathematics educators working in different state universities and responsible for Analysis courses, three pre-service…

This study investigated children's knowledge of the addition of fractions with unlike denominators. It focussed on the strategies used by children to add fractions with unlike denominators. A cross-sectional survey of Grade 8 children in schools in two districts in Ghana was used. A test on the addition of fractions with unlike denominators was…

When learning about fractions, teaching usually follows certain topics -- e.g. part of the whole, fraction equivalence, and size comparison. Not yet answered is whether students' conceptual and procedural knowledge of fractions is coherent between those topics. To answer this question, we performed a latent profile analysis of data from N = 1005…

The context surrounding today's college-going youth is different from when their parents pursued higher education in the late 1980s to early 2000s. I sought to understand how these parents, now as adults with children on the doorstep of their own college-going process, form knowledge about 21st century college-going and what sources these parents…

Sustainable mobility is an urgent topic to discuss in the primary school classroom, given the challenges in the mobility sector regarding sustainability issues and children's embeddedness in these circumstances. Therefore, it seems fruitful to address the topic within the approaches of Education for Sustainable Mobility (ESM) or Education for…
