Our world is shaped profoundly by science and technology, which are strongly interrelated. The importance of integrating technology in science teaching is acknowledged by many international science-teaching standards in recent decades. The present study aims at examining how undergraduate students utilize what they have learnt about the physics of…

Experimental results are presented concerning a bead sliding on a rotating, horizontal rod. If the rod rotates at constant angular velocity then the sliding speed in the radial direction increases exponentially with time, provided that the rotation speed is sufficient to overcome friction. Otherwise the bead rotates in a circular path of constant…

A simple experimental setup using a smartphone and a pair of speakers is presented to perform an accurate experiment on interference of two point sources. The proposed experiment allows simple but interesting measurements to be done to introduce students to interference and diffraction phenomena. As such, the experiment effectively introduces the…

Although there is wide evidence on young children's category learning, questions concerning how cognitive mechanisms and social mediation work collaboratively in this process remain sparse. Here, we study the impact of pedagogy in young children's categorization of novel artifacts. A before-and-after micro-genetic study compared 58 3-year-old…

The recent proliferation of research on children's supernatural concepts is noteworthy, as this work is necessary for a full account of human cognition. Despite this advancement in our field, there is a lingering tendency for scholars to exotify supernatural concepts; to treat them as distinct or special. Arguments have been raised that these…

Massive Open Online Courses (MOOCs) which enable large-scale open online learning for massive users have been playing an important role in modern education for both students as well as professionals. To keep users' interest in MOOCs, recommender systems have been studied and deployed to recommend courses or videos that a user might be interested…

This study aims to describe metacognitive interventions for students who experience suspension of sense-making when solving integration problems based on the characteristics of students' thinking. This research applied a qualitative research approach and provided essay tests followed by task-based interviews to classify students who experience…

Some students have misconceptions. Students' misconceptions make difficult to learn the new subject. Teachers need to know students' misconceptions and take precautions. One of the misconceptions in mathematics is about limits and continuity. In order for teachers to take precautions in this regard, they must have this experience during their…

Meaningful learning for conceptual change in science education should aim to help students change their existing misconceptions to develop an accurate understanding of scientific concepts. Although collaborative argumentation is assumed to support such processes, its value for conceptual change is unclear. Moreover, the roles of argumentative…

This study used fraction number line estimation tasks to evaluate students' developmental patterns, and the relationship of such tasks with whole number bias was explored. In total, 189 fourth-grade students in a northern Taiwan elementary school were followed over 2 years. The results demonstrated that the students' fraction learning development…

An ability to engage in system thinking is necessary to understand complex problems. While many pre-college students use system modeling tools, there is limited evidence of student reasoning about causal relationships that interact in diverging and converging chains, and how these affect system behavior. A chemistry unit on gas phenomena was…

An investigation was conducted into the common misconceptions in chemical equilibria, adopted by a sample of UK secondary school students. These included the characteristics of a dynamic equilibrium, the nature of the reactants and products at equilibrium, as well as the effect of conditions and catalyst on equilibrium. Suggestions for improved…

Kids are drawn to dolls and dump trucks, and crashing the two together might just be a child's favorite pastime. Who knew such a simple pleasure could serve as an accessible, compelling phenomenon for instigating investigations of force and motion. With a few inexpensive materials straight out of the toy box (literally, a doll, a dump truck, a…

This article explores the cognitive aspects of utopia in environmental and sustainability education. Utopia here is understood as the imaginary transformation of society, entailing a critique of society and its imaginary reconstruction aligned with the ideal of just and flourishing communities. To gain insight into the processes at play, I develop…

In this study, the skills of middle school teachers to write open-ended questions that measure higher-order mental skills were examined. For this purpose, 18 middle school teachers who worked in Artvin, Turkey and volunteered to participate in the study were asked to write questions. Teachers wrote open-ended questions for a total of 4 courses…
