This paper studies grade 7 (age 13) students' expressed understanding about the equal sign/notion of equivalence in order to investigate what aspects of the concept that could be seen as an established knowledge at lower secondary school/middle school. Using items from different instruments and combining these to a new one that covered a broad…

This study examines the relation between K-12 teachers' trust in artificial intelligence (TAI), their knowledge of AI (KAI), and their digital competence (DC). It further examines the relation between TAI and age, sex, teaching experience and International Standard Classification of Education (ISCED) levels. The study employed a comprehensive and…

Mathematical modeling has been positioned at the forefront of many educational levels globally because modeling reinforces purposeful problem-solving skills, connects mathematics to the real-world, and makes mathematics more meaningful and relevant. This article investigated K-12 practicing teachers' knowledge and attitudes toward mathematical…

The recent decades have seen enthusiastic calls for reconceptualizing English as a foreign language (EFL) education, taking into account the current socio-lingual status of English and how it is used "genuinely" for communication interculturally and internationally. However, a wide gap still exists between promulgation such as…

We examined the development of numerical magnitude representations of fractions and decimals from fourth to 12th grade. In Experiment 1, we assessed the rational number magnitude knowledge of 200 Chinese fourth, fifth, sixth, eighth, and 12th graders (92 girls and 108 boys) by presenting fraction and decimal magnitude comparison tasks as well as…

Geometry education is an important aspect of STEM education and career development, but it is often overlooked in K-12 education in the United States. Although there is some research on teaching geometry to students with learning difficulties at the elementary level, there is a lack of research on teaching advanced geometry skills at high school…

Creativity is a task-specific construct that exhibits diverse characteristics depending on the context it operates in. Currently, there is little consensus on how creativity can be defined and taught within STEM education. In this study, mathematics teachers' beliefs about STEM creativity and their pedagogical approaches to teaching creativity…

The purpose of this investigation was to determine the impact of students' background knowledge and how they utilized "don't know" affordances to comprehend and learn from text. In two studies, over 8,000 middle and high school students interacted with a content-area learning environment in which they answered a series of background…

The article presents findings from a Czech environmental literacy survey conducted in 2020 on a sample of 6th (N = 3773), 8th (N = 21518), and 9th graders (N = 4368). Specifically, the effect of environmental and sustainability education (ESE) as well as the effect of gender and age on environmental knowledge, attitudes, beliefs, place attachment,…

Considering the individual differences in previous content knowledge, skill, and attitude, which types of learners are suitable for AR is a valuable but complex question. The study used quasi-experimental design, and divided 97 10th-grade students into two groups: traditional group (N = 48) and AR group (N = 49), who participated in 4-week organic…

Children are worried about climate change. Educational settings provide an opportunity to help children cope with their worries, but teachers do not always feel comfortable doing so. One reason for hesitancy may be their own negative emotions. This paper describes findings from a survey of climate-aware teachers, looking at their perceptions and…

In this article we present an overview of four studies investigating Greek secondary students' conceptual and procedural knowledge of fractions. We discuss the problem of defining conceptual and procedural knowledge, and the implications of adopting one particular definition over others. We draw on the studies and their results to discuss the…

We constructed and calibrated an instrument targeting conceptual and procedural fraction knowledge. We used this instrument in a quantitative study with 126 secondary students (7th and 9th graders), testing the hypothesis that there are individual differences in the way students combine the two types of knowledge. Cluster analysis revealed four…

Trauma and the exposure of trauma among adolescents can significantly impact a child's ability to find success in the school setting. Trauma-affected students can experience difficulties physically, mentally, emotionally, and developmentally, affecting their academics and behavior. This study explored the perceptions of teachers and the causes and…
