The research presented in this dissertation describes a series of studies characterizing and assessing undergraduate chemistry students' knowledge related to the epistemic nature of scientific models and modeling. Engaging in authentic scientific practices, for instance, developing and using scientific models, has been identified as an important…

Various similar primary studies report varying impacts of applying blended problem-based learning (Blended PBL) in improving students' 21st-century skills. This study aims to group similar studies on the effect of blended PBL on students' 21st-century skills in science learning through meta-analysis. In addition, studies were analyzed on…

This dissertation investigates the voluntary usage of clickers to answer in class multiple-choice questions in general chemistry courses and its effect on student performance. The first study explored the demographic composition of two sequential introductory level chemistry courses over six terms. No difference in voluntary usage of the clicker…

The transition students face moving from Further Education (FE) to Higher Education (HE) can be a daunting experience. This transition to HE may require a substantial adjustment to a student mindset recognising that they would be responsible for their own learning and their eventual success compared to a FE environment where student learning is…

Background: Digital simulations are emerging technologies in science education that allow students to visualise abstract concepts and enable science teachers to conduct laboratory work/experiments online. Objective: To determine teacher readiness, the study focused on their cognitive skills and knowledge and perceptions of the use of digital…

Virtual classrooms based on the metaverse or virtual reality are useful and effective for imparting basic chemistry concepts. Interactive and immersive environments can effectively teach fundamental chemistry concepts, such as chemical bonding and formulas, thereby making these otherwise abstract and intangible ideas more accessible and…

As environmental awareness grows, so do questions about the environmental impact of photography, in particular traditional film development and processing, which includes the use of plastics, gelatine and other environmentally harmful chemicals notwithstanding water usage and waste. Pioneering practice and research into sustainable alternatives to…

General Chemistry courses are often challenging for first-year college students preparing for science, technology, engineering, and mathematics (STEM) programs. These courses are among the STEM gateway courses in which many students struggle to get through, or are weeded out. This is partly due to the use of ineffective study strategies such as…

A comprehensive educational framework is provided by the Conceive-Design-Implement-Operate (CDIO) which is particularly relevant to engineering and applied sciences. This paper investigates the application of the CDIO approach in the field of chemistry pedagogy in Vietnam focusing on its adaptability to the current educational demands and its…

Learning the periodic table of elements can pose a challenge for students due to the complex organization and relationships between the different elements. Game-based interventions have been shown in past studies to be one of the feasible ways to overcome this challenge. In this research, a tabletop game, called "Little Periodic" was…

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…
