Demonstration of a colorimetric approach for nucleic acid detection represents an attractive educational experiment for chemistry undergraduate students in the time of coronavirus pandemic. Herein, a rapid and vivid detection method that visualizes the presence of a specific DNA sequence is described. The plasmon resonance of gold nanoparticles…

The physics that underpins modern technology is based on Einstein's theories of relativity and quantum mechanics. Most school students complete their compulsory science education without being taught any of these Einsteinian concepts. Only those who take a specialised physics course have the opportunity to learn modern physics. In 2011, the first…

In the high school context, many students only solve photoelectric effect phenomena based on the equation for maximum kinetic energy and its relationship to work functions. While the story behind this phenomenon constitutes an exciting educational experience if conveyed in an attractive visual manner, many physics teachers are concerned that…

The increasing use of online virtual laboratories (OVLs) in educational institutions as a recent educational technology application necessitates developing a new educational platform for assisting instructors in using such technology in the teaching process without web programming obstacles. The OVLs are online environments that provide students…

Due to the COVID-19 pandemic, social distancing restrictions are in place in most public settings, and the undergraduate laboratory is no exception. In order to accommodate social distancing requirements, many laboratory exercises are being redeployed in an online format, which deprives students of experiential learning opportunities in a real…

Here, we present an interdisciplinary educational project intended for high school chemistry that is focused on the establishment of a mathematical model to describe the relationship between conductivity and concentration, while linking chemistry to mathematics with the help of computer software. The project was designed to help high school…

The world is confronted with wicked environmental problems that cannot be well understood or acted upon without addressing their ethical dimensions. Research shows that official science curricula on environmental science and ecology topics are shaped by the scientific discourse and environmental discourses of "ecological modernization"…

This study investigated the organizational impact of computer technology on four secondary science teachers' teaching actions using the construct of community of practice. The organizational impact of computer technology refers to teachers' styles and creativity in constructing personally pertinent individual models of teaching when using computer…

The meaning-making practices of science are multimodal and include representational forms such as spoken and written language, diagrams, graphs, equations, and images. Science learning proceeds through an ever-increasing grasp of such resources. This study aims at providing insight into how a combination of Interaction Analysis (IA) and social…

The objective of this work was to evaluate the implementation of a metavisual strategy for students to revise and self-regulate concepts arising in a study of a chemical reaction between ions. For this purpose, two chemistry education undergraduate students at a Brazilian public university carried out an investigative activity, involving…

The purpose of the study is to determine whether the solitary and tablet assisted presentations of direct instruction method differed in terms of efficiency and effectiveness in teaching science topics to students with intellectual disabilities and to obtain the opinions of participating students and their real-time teachers about two different…

Access and personalized instruction required for laboratory education can be highly compromised due to regulatory constraints in times such as COVID-19 pandemic or resource shortages at other times. This directly impacts the student engagement and immersion that are necessary for conceptual and procedural understanding for scientific…

The interaction between water and surfaces is observed in our daily lives and is used in laboratories to study materials properties, such as interfacial tension. Making the connection between fundamental scientific phenomena and everyday observations is a powerful method of highlighting the importance and relevance of science to the K-12…

The development of good learning resources on inquiry learning model with science literacy as a strategy to facilitate active learning has become a trend in education. Critical thinking ability is needed as a strategy to build students competencies in problem solving and discovery as required in science learning. This study aims to develop a set…

This study evaluated how the process of teaching scientific methodology occurs in technical courses in integrated high schools. The qualitative case study was conducted through documentary analysis (based on regulations and pedagogical projects) and semi-structured interviews with teachers (n=7), coordinators (n=3), and students (n=16) of the…
