Organic chemistry students often struggle with reaction mechanisms, particularly in how they are proposed and justified. In this activity targeting second year organic undergraduates, students used infrared spectroscopy (IR) to track the reaction progress of two distinct aldol reactions and used polarimetry to analyze the stereoselectivity of…

Innovative activities carried out during school laboratory sessions include 'flipped learning' (FL), which is an interactive learning environment where the teacher guides students learn individually. This study examined the impact of the adoption of the FL approach on the academic performance of 2nd year science student teachers enrolled in the…

In science class, students learn by making and living information, enabling them to make sense of knowledge effectively and permanently and to associate it with daily life. Applied science courses make learning more qualified. While science teaching is carried out in application areas such as laboratories, virtual laboratories are used with the…

Over a decade has passed since faculty members' goals for the undergraduate chemistry instructional laboratory were first investigated on a large, national scale in the United States. This study revisits these goals, using data from a 2022 national survey of chemistry faculty members in the United States (n = 521) to investigate current…

The Investigative Science Learning Environment (ISLE) approach to learning and teaching holds as one of its core tenets that students should learn physics by engaging in the same processes through which physicists develop new knowledge. One key skill necessary for this is hypothetico-deductive reasoning. In this study, we explored how the…

Coagulation is an important process in the context of water purification; and the seed protein of the moringa tree ("Moringa oleifera") is a remarkably effective coagulant. The laboratory course described here is designed to provide high-school students with a stepwise, hands-on experience in investigating the protein-rich coagulant…

Student profiling on the use of technology for teaching, learning and assessment has the potential to enable educators to enhance their transformational teaching strategies. Therefore, this study explored the views of students on use of technology to facilitate online learning during COVID-19. The study employed a quantitative approach to collect…

Academic food security aims to provide students with sufficient access to knowledge (one key academic nutrient) in order to limit intellectual hunger. In this analogy, the student is seen as a consumer of knowledge. Academic food sovereignty, on the other hand, aims to shift the focus from student knowledge consumership to student knowledge…

The concept of co-amorphous systems is introduced in an integrated laboratory experiment, designed for advanced chemistry students, using solvent-free, environmentally friendly mechanochemistry. The dual-drug naproxen-cimetidine co-amorphous system (NPX-CIM) is investigated as an example of the emergent field of medicinal mechanochemistry.…

Materials science research has expanded significantly in recent years; a multidisciplinary field, home to an ever-growing number of chemists. However, our general chemistry degree courses have not changed to reflect the rise in interest in this topic. In this paper, we propose a laboratory experiment for the undergraduate chemistry practical…

Chemistry in water is an emerging field that fulfills the fifth principle of green chemistry: replacing toxic organic solvents with their benign counterparts. Although some pharmaceutical industries have developed and adopted chemistry in water, its implementation in teaching laboratories is still limited. Therefore, we have designed an experiment…

The COVID-19 pandemic, which emerged in early 2020, forced educational institutions in Thailand to chiefly rely on online learning during the government mandated lockdown for almost two academic years. Although migration to the online format seems to suit lectures, it is inadequate for laboratory courses since students could not do the experiment…

A two-component undergraduate laboratory experience has been developed by students in a senior level capstone course. The first component is a 3 h laboratory experience dedicated to the rapid synthesis of a metal-organic framework (MOF-808) in aqueous solution using readily available reagents and equipment. During the second component, MOF-808 was…

A cooperative-learning jigsaw-style activity was developed to create opportunities for introductory organic chemistry students to discuss and decipher [superscript 1]H NMR spectra. Students cooperatively interpreted spectra that contained both pure and mixed solvents, building consensus through explanation and argumentation on what each spectrum…

Purpose: The purpose of this study was to develop the augmented reality (AR) educational program combined with the instructional guidance for supportive learning, which enhanced the thinking process cooperative discussion and problem-solving skills in chemistry subject. Design/methodology/approach: The method used the quasi-experimental research…
