How can we succeed in meeting the challenges of the future world in the best possible way? In order to support children in their development into optimistic, self-effective adults, it is necessary to find out how children perceive their world and how they combine these perceptions with their cognitive knowledge. This article examines the question…

One of the basic science process skills, number and space relation, is used to transform a twodimensional object into a three-dimensional shape or express symmetry axis of the objects. The aim of this research was to determine the number and space relation skills of pre-service science teachers in order to train more qualified science teachers…

We present a simple procedure to make an augmented reality app to visualize any chemical 3D model. The molecular structure may be based on crystallographic data or from computational modeling. This guide is made in such a way that no programming skills are needed, and the procedure uses free software and provides a way to visualize 3D structures…

In 2 experiments, college students read a 4-paragraph text on how the human circulatory system works and were instructed to form a mental image of the events described in each paragraph from the perspective of their own body (first-person perspective group) or from the perspective of a fictitious person facing them (third-person perspective…

Peer-review software is often used to allow authors to evaluate their code and its technical text content. In education, peer review is a common practice used not only to evaluate the quality of academic research but also to measure students' engagement in the classroom. In visualization education, numerous researchers have addressed techniques of…

For the last decade, remedial spatial visualization training has been offered to first-year engineering students in traditional classroom settings where students attend class and interact face-to-face with an instructor and peers. An alternative to the traditional pedagogical approach is a multi-modal blended learning format that combines in-class…

This study aimed to understand teachers' classroom practices using computer-based simulations (CBS) when teaching electrolysis. The study was framed by the Consensus Model of Pedagogical Content Knowledge. Convenience and purposive sampling were used to select three experienced chemistry teachers from three schools in Eswatini (Swaziland).…

The aim of this research is to introduce a method of constructing knowledge structures which represent the relationships among the knowledge items in a pedagogically useful way. A prototype, "MyTeLeMap," was implemented to support both learners and instructors. Learners could visualize the knowledge structures of different knowledge…

This article describes the findings of a qualitative phenomenographic study that explored students' engagement from the perspective of the students. It describes how the participants perceived their engagement when they learned social studies using GIS Story Maps. Qualitative data collection involved classroom observations, student-written…

Sculpting representations of human organs out of modeling clay is an acknowledged method of teaching anatomical structures. Because of its potential to provide detailed spatial information, stereoscopic imagery can be understood to function as a suitable template for such sculpting tasks. Currently, it is unknown whether the advantages of…

A curriculum map is a visualisation of relationships within and between a curriculum or curricula. Curriculum mapping refers to the method for creating and using the curriculum map, however this term is used broadly and encompasses a variety of methodological approaches. Often, researchers in the field of curriculum studies conduct curriculum…

The aim of this study was to improve pre-service teachers' ability to infer cross-sections of geometric solids with Wolfram demonstrations and Mathematica in Analytic Geometry II course. The study was conducted with third year students studying Elementary Mathematics Education. In this study, the pre-test--post-test control group design was used.…

Many students are not good at geometric proofs. One reason for this is that it is possible to memorize the proof procedure explained by the teacher without understanding the structure of a geometric proof. So far, we have developed a web-based application that supports the understanding of the "structure of geometric proofs" in junior…

When a shock wave interacts with a contact discontinuity, there may appear a reflected rarefaction wave, a deflected contact discontinuity and a refracted supersonic shock. The numerical simulation of shock wave refraction at a plane contact discontinuity separating gases with different densities is performed. Euler equations describing inviscid…

In this study we analyze how learners constitute what it means to learn and know a song. This is investigated in the context of four 9- to 10-year-old children in dyads teaching each other to sing a song of their own choosing. How the children take on this task is studied in terms of how they dialogically co-construct pedagogical and musical…
