The ground-breaking image of a black hole's event horizon, which captured the public's attention and imagination in April 2019, was captured using the power of interferometry: many separate telescopes working together to observe the cosmos in incredible detail. Many recent astrophysical discoveries that have revolutionized the scientific…

Dropout and low academic performance at university level constitute a big current challenge. In this work, materials comprising different interactive tools were developed following instructional design, rooted in the cognitive load theory. They were applied in a first-year lecture chemistry course to tackle low academic performance and high…

This work presents a homemade multirole 3D-printed modular spectrometer(MPMS), which can be easily assembled like bricks and expanded with several modules to measure different types of spectra, such as UV-vis absorption, fluorescence emission, flame emission/absorption, glow discharge, and even Raman spectra. The spectrometer is designed to be…

Assumptions about the feasibility of teaching chemistry laboratories online have been challenged by the ongoing COVID-19 pandemic. We argue that, despite the fact that pandemic social distancing restrictions will be eventually eliminated, the development of quality digital laboratory resources must continue to receive attention from the chemistry…

Background: Educational board games have been receiving attention from educators in recent years. Designing the rules of board games based on cognitive theory, and further analysing educational board games from more dimensions are important issues that warrant further study. Purpose: The research designed a board game called Chemistry Story to…

Three-dimensional (3D) modeling is a recent, innovative approach to teaching anatomy. There is little literature, however, to suggest how 3D modeling is best used to teach students and whether or not students can gain the same level of understanding as they might use more traditional, hands-on, teaching methods. This study evaluated the use of a…

This study investigates science teachers' perceptions of their level of Technological Pedagogical Content Knowledge (TPACK) and the challenges they face in integrating technology into the classroom. Using a case study approach, data were collected through the TPACK scale and semi-structured interviews with 102 science teachers. The results reveal…

The preponderance of visually oriented and visually complex concepts and information in science classrooms poses significant challenges to learning among students with visual impairment (VI). It is acknowledged that the good quality of practical work promotes the engagement and interest and curiosity of students as well as developing a range of…

We developed new teaching materials, electrical resistors and capacitors, using carbon nanotube (CNT) paper and carbon fibre (CF) paper to foster students' creative thinking, thereby deepening and extending learning. Using a CNT-paper electrical resistor, it is possible to elucidate the dependence of the resistance value on the length and width.…

Recently, there has been an increased interest in how science and society interrelation is presented and discussed in science courses. Socioscientific issues (SSI) approach is one way of promoting teaching and learning of science through social contexts. In the present study, we focus on the artifacts 12 pre-service primary teachers (PPTs)…

In all fields of chemistry, it has become essential to use quantum chemical calculations and machine learning for explaining and predicting chemical phenomena. However, it is challenging to apply textbook knowledge to practical research. In this study, we developed teaching material based on computational chemistry to promote the integration of…

Powder diffraction is one of the most widely used analytical techniques for characterizing solid state materials. It can be used for phase or polymorph identification, quantitative analysis, cell parameter determination, or even full crystal structure analysis using the powerful Rietveld refinement method. As with much of modern crystallography,…

"Leave no alternative science idea unchallenged!" could be the slogan of this second edition of "Uncovering Student Ideas in Science, Volume 2." Like the others in the bestselling series, this book is loaded with classroom-friendly features to pinpoint what your students know (or think they know) so you can adjust your teaching…

Numerous studies demonstrated that the meaning-making of scientific knowledge is affected by the design of multimodal science texts. Various modes are co-operated together in certain inter-semiotic mechanisms to produce meaning in multimodal texts. Based on this perspective, this research seeks to investigate the effect of mode level in science…

Many science educators have argued in favour of including socioscientific issues (SSI) in general, and ethical issues in particular, in school science. However, there have been a number of objections to this proposal, and it is widely acknowledged that such teaching places additional demands on science teachers. This study examined the curricula,…
