An experimental design by combining hydrogel and ethylenediaminetetraacetic acid disodium salt (EDTA) for visually displaying chemical complexation reactions is developed. The Na[superscript +] ions on the [alpha]-l-guluronic acid (G) unit of the sodium alginate molecule undergo an ion exchange with a divalent cation, so that the G units are…

Virtual chemistry laboratory modules were investigated as a potential learning resource that complements traditional in-person experiments. In collaboration with a high school instructor, we designed two interactive modules, "Rates of Reaction" and "Models of Organic Molecules," which became part of a previously reported online…

The current study ascertained the influence an instructional module had on enhancing students' understanding of chemical reactions and acid-base topics. The sample size for this study consisted of 197 students, including 101 in an "experimental" group and 96 in a "control" group, selected from schools in two Districts…

A new module designed to ease the transition from school to university was devised and implemented at Cardiff University School of Chemistry. Two iterations of the module are described, both of them conducted under restrictions imposed by COVID-19 pandemic regulations. Over a two-week period, students attended 15 different sessions, each designed…

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…

In addressing the need for safer and more accessible chemistry lab procedures, this work integrates green chemistry and small-scale chemistry concepts to serve as a laboratory model for both qualitative and quantitative analyses of iron(III). An aqueous extract of Indian gooseberry is utilized as a natural reagent to form a complex with iron(III),…

There is an increasing need for research chemists and biochemists to have a basic familiarity with computer programming. Adding programming content to already crowded STEM undergraduate curricula, however, can be challenging. When programming content is introduced within the chemistry curriculum, it is most often incorporated into upper division…

Over the past 20 years, significant effort has been devoted to advancing the modular approach to teaching chemistry laboratory courses. The development and implementation of two modules are presented here for teaching a second-semester physical chemistry laboratory course using the modular approach: an inquiry-based module concerning proteins and…

This study aimed to develop an e-content module for Chemistry Massive Open Online Course (MOOC). It examined the validity, reliability and student's perceptions on content, usability, design and effectiveness of the module. This is a design and development study and the e-content module was developed based on ADDIE instructional design model.…

Teaching the fundamentals of chemical kinetics on the college level is challenging to teachers and students alike due to its abstract nature of concepts and limited connection with real context applications. This study consisted of two phases starting with designing a chemistry education for the sustainable development-based learning environment…

Massive Open Online Course (MOOC) is a new trend in flexible education due to its flexibility to study anything, anywhere and anytime. It has the potential to attract a huge number of learners to study courses unlimitedly via the online platform. This is a design and development study where a Chemistry MOOC was developed in an OpenLearning…

Solving STEM problems requires that data (numbers and units) from a word problem be substituted into a mathematical equation(s) for solution. However, solving STEM problems is an implicit process that provides little or no guidance for the problem solving process. In this study symbols linking the data to the mathematical equation(s) are used to…

For many years, a key driver for Higher Education Institutions (HEIs) has been ensuring that students are prepared for employment post-graduation. This has often resulted in HEIs providing specific modules of study focussing on employability and soft skills. The existing research literature presents a variety of strategies for embedding…

The purpose of this descriptive case study was to develop pre-service chemistry teachers' Technological Pedagogical Science Knowledge (TPASK) through novel computational chemistry modules. The study consisted of two phases starting with designing a computational chemistry based learning environment followed by a case study where students'…

This research is an innovative development on teaching materials in order to intensify the movement of "Satu Guru Satu Buku (SAGUSABU)" and to prepare skillful media users on mastering Information and Communication Technologies (ICT). The resulting prototype is an interactive e-module named Chemistry Magazine which have two editions:…
