Using social network analysis, we sought to characterize the professional collaboration and advice networks among rural science teachers. Furthermore, we explored how the characteristics of individual teachers and distance between teachers affected the likelihood of forming connections. Science teachers in publicly funded rural schools were asked…

It is difficult for students to learn the concepts of chemical laboratory safety education from actual experiences because the traditional teaching model prohibits students from performing dangerous operations. Therefore, this study develops a novel mixed reality-based chemistry experiment learning system (MRCELS) to allow learners to conduct…

An undergraduate-level Computational Chemistry project was incorporated initially into a Physical Chemistry course and then into the laboratory curriculum in the subsequent application. Before the introduction of the project, the lectures covered quantum chemistry, spectroscopy, and kinetics while simultaneously including computational chemistry…

Students are encouraged to develop a set of scientific skills and disciplinary practices common across the STEM disciplines. These skills (scientific inquiry, quantitative skills, laboratory and computational skills, communication skills, teamwork/interpersonal skills, interdisciplinary competency) are highlighted as important in discipline-based…

This technology report presents the main features of a free digital educational tool which aims to introduce middle school level students to the comprehension of the particulate nature of matter in the three states (i.e., solid, liquid, and gas) and during phase transitions. This digital tool is available and is freely accessible online. Its…

This study explores the integration of STEM principles into chemistry education through the redesign of the topic Chemical Reactions for initial teacher training. The aim was to develop and evaluate an innovative teaching module that fosters key competences--knowledge, skills, and attitudes--via student-centred, context-based, and…

The present study sets out to address a critical academic feature necessary to understand research articles (RAs) through investigating foreign language (FL) Tunisian doctoral students' awareness of the kind of relationship between text, writer, and readership in English research articles across three distinct disciplines: Linguistics, Economics,…

Compelling evidence, from multiple levels of schooling, suggests that teachers' knowledge and beliefs about knowledge, knowing, and learning ("i.e.," epistemologies) play a strong role in shaping their approaches to teaching and learning. Given the importance of epistemologies in science teaching, we as researchers must pay careful…

The logistics and cost of running large class tutorials to improve learning for students in high enrolment courses raise questions about whether the associated effort and cost are worthwhile. The option to replace these class activities with online homework with its promise of built-in feedback is attractive. Using an activity theory lens and an…

Critical thinking, a rational and open higher-order thinking mode in human cognition, is becoming imperative to success in modern life. Therefore, cultivating students' critical thinking has become a common goal of education reform worldwide. Teachers play a crucial role in cultivating students' critical thinking. However, existing studies have…

Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

This study determined the influence of the competency of teachers and the laboratory environment in an online setting on the students' science process skills using mixed methods approach-convergent design. Participants of the study were 2nd year students from different Higher Education Institutions in Region XI, Philippines. Further, to gather…

Chemistry is considered a difficult subject by most students. Its difficulty lies in Chemistry's complex and abstract nature. This highly abstract nature requires constant interplay and coordination between the macroscopic, particulate, and symbolic representations. Experts can successfully navigate the various representations without overloading…

Background: Although cutting-edge chemistry research can be an interesting and motivating context for students in pre-university education, few characteristics of supportive and effective learning materials based on such contexts are available. Purpose: In this study we investigated the design, implementation, and evaluation of context-based…

This study explored, using a qualitative research design, the experiences of chemistry laboratory staff and students engaged in chemistry laboratory exercises delivered online. The research was completed over two semesters for the academic year 2020-2021 at The University of the West Indies, St. Augustine Campus in Trinidad and Tobago. The group…
