This paper comprises the results of a design study that aims at developing a theoretically and empirically based learning trajectory on statistical inference for 9th-grade students. Based on theories of informal statistical inference, an 8-step learning trajectory was designed. The trajectory consisted of two similar four step sequences: (1)…

This study investigated the effect of using the technical visual arts lessons' material on visualization skills and attitudes. For this purpose, an augmented reality application called BTRS was designed. The application was created using Unity3D, 3Ds Max, and Vuforia programs. The study was conducted for eight weeks, with a total of 33 students…

Aim/Purpose: This paper aims to evaluate the influence of an augmented reality mobile application on improving secondary students' visualization and comprehension of geometric concepts. Background: The study involved developing an AR app named Geometria to enhance geometry education. Methodology: In a specialized boarding school in Kokshetau,…

Three-dimensional visualization of molecular simulations in virtual reality (VR) is an emerging teaching tool in chemical education. This work describes a VR application which can generate a 3D molecular dynamics (MD) simulation from arbitrary molecular structures and renders that MD simulation trajectory on a VR headset in real-time. This system…

An application for visualizing the aggregation of structureless atoms is presented. The application allows us to demonstrate on a qualitative basis, as well as by quantitatively monitoring the aggregate surface/volume ratio, that the enhanced reactivity of nanoparticles can be connected with their large specific surface. It is suggested that,…

Ocean Acidification (OA) is an emerging environmental issue that is still largely unknown to the public and in its infancy in terms of educational strategies. OA teaching material should address the specific challenges that educators face while building learners' understanding of OA. The objective of this study is two-fold. First, we identified…

Skills in science, technology, engineering, and mathematics (STEM) are increasingly in demand. Theoretical knowledge and formulas alone are frequently not sufficient to understand complex phenomena. Simulations are a valuable tool to support the conceptual understanding by visualizing invisible processes. The constant interaction with the learning…

Molecular storytelling combines three-dimensional (3-D) structure visualization, chemical and biological knowledge, and multidisciplinary functional information from various bioinformatics data resources to generate new knowledge. It prepares students for independent and interdisciplinary learning, facile navigation of public databases to gather…

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…

The 3D visualization program paves the way for the development of virtual reality. This study produces a 3D visualization program in virtual reality to increase high school students' critical thinking skills and scientific attitude. The Research and Development (R&D) method was based on the ADDIE model - analysis, design, develop, implement,…

It is often difficult for students to develop an intuition about molecular processes, which occur in a realm far different from day-to-day life. For example, thermal fluctuations take on hurricane-like proportions at the molecular scale. Students need a way to visualize realistic depictions of molecular processes to appreciate them. To this end,…

STEM instruction often uses visual representations. To benefit from these, students need to understand how representations show domain-relevant concepts. Yet, this is difficult for students. Prior research shows that physical representations (objects that students manipulate by hand) and virtual representations (objects on a computer screen that…

Understanding key concepts in molecular biology requires reasoning about molecular processes that are not directly observable and, as such, presents a challenge to students and teachers. We ask whether novel interactive physical models and activities can help students understand key processes in viral replication. Our 3D tangible models are…

Scientific visualisations such as computer-based animations and simulations are increasingly a feature of high school Science instruction. Visualisations are adopted enthusiastically by teachers and embraced by students, and there is good evidence that they are popular and well received. There is limited evidence, however, of how effective they…

Of the eight practices of science identified in "A Framework for K-12 Science Education" (NRC 2012), helping students develop and use models has been identified by many as an anchor (Schwarz and Passmore 2012; Windschitl 2012). In instruction, disciplinary core ideas, crosscutting concepts, and scientific practices can be meaningfully…
