Rapid development in the field of reticular chemistry has allowed scientists ever-increasing control over the design and synthesis of crystalline porous materials. The promise that this field has in the development of next-generation materials for numerous applications (gas storage and separation, catalysis, chemical sensing, electronics) relies…

In this organic chemistry laboratory experiment, students are guided through a series of exercises to understand the behavior of compounds during liquid-liquid extraction. Aspects of density, structure, solubility, acid-base theory, and pK[subscript a] are all incorporated into activities that students complete in groups. After using their initial…

Purpose: This study developed and applied the chemistry learning module integrated with green chemistry and ethnoscience to develop generic skills of science and soft skills of conservation of high school students in Central Java, Indonesia. Methods: The participants consisted of Chemistry education students (22 students), students from MAN I…

This work is aimed at finding out the effect of the implementation of the metacognitive learning strategy on the quality of prospective chemistry teacher's scientific explanations. This study used a quasi-experimental method with a pretest -- post-test control group design. The participants of this research were the students of two classes of…

In this review article, formulae based on innovative mnemonics have been discussed to create interest and remove phobia of students in the field of chemical education. Educators can use these numerous mnemonics in their teaching style in the classroom lectures after discussing conventional methods to make chemistry intriguing. Here, I have tried…

Programmatic text analysis can be used to understand patterns and reveal trends in data that would otherwise be difficult or impossible to uncover with manual coding methods. This work uses programmatic text analysis, specifically term frequency counts, to study nearly 10,000 chemistry thesis and dissertation titles from 1911-2015. The thesis and…

Despite its vital importance in our lives, chemistry is inadequately represented in most museums. Issues such as safety, replenishing and disposal of chemicals, supervision required, and cost are constraints that have limited the number and size of chemistry exhibits. Taking into account the constraints, a 21-station interactive and inexpensive…

A unique demonstration with ball-rolling mechanisms has been developed to illustrate the basic principles of mass analyzers as components of mass spectrometers. Three ball-rolling mechanisms mimicking the currently used mass analyzers (i.e., a quadrupole mass filter, a magnetic sector, and a time-of- flight) have been constructed. Each mechanism…

A simple, inexpensive, discovery-based experiment for undergraduate organic laboratories has been developed that demonstrates the Lewis acid and shape-selective properties of zeolites. Calcined zeolite Na-Y promotes the electrophilic aromatic bromination of toluene with a significantly higher para/ortho ratio than observed under conventional…

Students often struggle to determine whether changes in matter are physical or chemical; for example, they may have difficulty labelling a candle melting as a physical change but a candle burning as chemical change. Here we describe a lesson that we used to integrate conceptual learning about physical and chemical changes using the…

Reactivity III is a new course that presents chemical reactions from the domains of organic, inorganic, and biochemistry that are not readily categorized by electrophile-nucleophile interactions. Many of these reactions involve the transfer of a single electron, in either an intermolecular fashion in the case of oxidation/reduction reactions or an…

The previous research result showed that the learning model based on the investigation could increase the students' critical thinking skills. The aim of this research was to measure the effectiveness of the using of problem-based learning model to increase the students' critical thinking skills. The research design was quasi-experiment by using…

This study aims to determine the effect of the use of learning media Virtual Reality Laboratory (VR-Lab) on the conceptual understanding of Senior high school students on the concept of electrolytes and non-electrolytes. The learning media used were developed using models adapted from the ADDIE model, while the type of research as a whole uses…

Green chemistry and sustainable development have become increasingly important topics for the education of future chemists, but the implementation of green chemistry into the chemistry curriculum requires significant efforts from teachers, especially in laboratory education. A student-driven development of a greener synthesis of Lidocaine was…

Computational approaches toward simulating chemical systems and evaluating experimental data has gathered great momentum in recent years. The onset of more powerful computers and advanced software has been instrumental to this end. This manuscript presents a hands-on activity which trains students in basic coding skills within the Matlab…
