When the thermal expansion of water is discussed in school or university lessons, functional relationships are often inferred without considering measurement uncertainties. Moreover, in some learning materials, the goal of experimentation and the experimental setup do not match. This creates the wrong picture of scientific practice. In this…

Since the viscous behaviour of liquids is evident in many everyday situations, it is plausible to assume that students have (pre-)conceptions about the physics behind these phenomena. As yet, no reliable studies exist on this topic. Therefore, the present study aims to address this research gap by exploring secondary school students' conceptions…

In Japan, research activities by junior and senior high school students show an upward trend. However, there are limited examples of research activities in the field of elementary particles and atoms. This is due to the difficulty associated with procuring research tools such as accelerators or particle detectors. Therefore, we hosted the 'Accel…

We developed a three-dimensional motion tracking system that displays trajectories as augmented reality in real time on a tablet device. The features of this system are as follows: (1) the three-dimensional trajectory can be observed from any direction. (2) Velocity and acceleration can be visualized as augmented reality. The device consists of an…

This article analyses the impact of the role and significance of the virtual laboratory on ninth-grade lyceum students' attainment of more-in depth scientific knowledge and improved practical skills in the physics topic area of electromagnetism. Pedagogical experiments were conducted at the Baku European Lyceum. The results show that the virtual…

Enhancing the problem-solving skills of learners belonging to socio-economically disadvantaged groups is a great concern in general and particularly in the Indian context. Problem-solving skills are the most important skills of the 21st century for all learners to acquire necessary competencies. The main purpose of this work is to investigate the…

The Promoting Radio Astronomy in Ghana through School visits and Astronomy Clubs (PRAGSAC) project was an intervention to promote astronomy education in schools in Ghana. It was initiated by a group of enthusiastic students who were trained in radio astronomy and astrophysics under a Royal Society/Newton Fund UK project termed Development in…

'It is the belt!' This is how middle school teachers in a science teaching professional development program rationalized why they believe Orion is the most recognizable of all constellations in the night sky. It was from this foundation that we chose Orion to be the focus of a four-phase ethnoastronomy-based project reported here. Ethnoastronomy,…

It has become increasingly common for high-school students to see media reports on the importance of quantum mechanics in the development of next-generation industries such as drug development and secure communication, but few of them have been exposed to fundamental quantum mechanical concepts in a meaningful classroom activity. In order to…

There is growing interest in the introduction of Einsteinian concepts of space, time, light and gravity across the entire school curriculum. We have developed an educational programme named 'Einstein-First', which focuses on teaching Einsteinian concepts by using simple models and analogies. To test the effectiveness of these models and analogies…

It has long been argued that nature of science (NOS) is an important part of science teaching. In the literature, many different approaches to NOS have been suggested. This article focuses on a storytelling approach, and builds on data from audio recordings from three middle-school (school year 6) classrooms. The three science classes are run by…

Research has shown that project-based learning promotes student interest in science and improves understanding of scientific content. Fostering student motivation is particularly important in accelerated science and technology programmes for talented students, which are often demanding and time-consuming. Current texts provide little guidance on…

Many researchers have documented the difficulties for learners of different ages and preparations in understanding basic astronomical concepts. Traditional instructional strategies and communication media do not seem to be effective in producing meaningful understanding, or even induce misconceptions and misinterpretations. In line with recent…

Optical fibre communication enables the global internet, but few youths ever learn about how it works, even at a basic level, until tertiary education. While some middle school curricula might include simple geometrical optics concepts like reflection and refraction, they often lack contextual linkage to worldwide telecommunications. Through our…

For this article, we use a 3D printer to print a surface similar to universal gravitation for demonstrating and investigating Kepler's laws of planetary motion describing the motion of a small ball on the surface. This novel experimental method allows Kepler's laws of planetary motion to be visualized and will contribute to improving the…
