The activity proposed in this study aims to investigate the equilibrium between the liquid and vapor phases in a mixture of water and acetic acid, both of which are volatile substances. High school students can easily determine the composition of the liquid phase and its corresponding vapor phase at equilibrium using a simple and conceptually…

An approach to online laboratory exercises for analytical chemistry students with demonstrated practical exercises through the use of remote-controlled gas chromatography (GC) instrumentation is discussed. The approach allows for a practical-based learning activity to be carried out by students who are unable to attend in-person laboratory…

In this study, we analyzed how general chemistry students generated experimental designs corresponding to general chemistry questions such as the ones typically found in general chemistry textbooks. We found that students were very successful in including experimental design aspects that were explicitly mentioned in the general chemistry…

The carbonyl group of an aldehyde or ketone reacts with different types of nucleophiles through a nucleophilic addition reaction. When the nucleophile is water, the product obtained is a "gem"-diol or geminal diol. This functionalization is unstable and quickly reverts to the parent carbonyl group. The chemistry of "gem"-diols…

The relationship between surface area and dynamics of processes can be demonstrated by adding iron at room temperature to liquid nitrogen. The rate at which the liquid nitrogen boils to produce gas is related to the surface area of the iron. Adding iron in the form of consistent units that have measurable sizes can be readily connected to…

Although Ohm's law contains various possibilities in teaching and learning scientific inquiry, it is rare for students to experience an authentic inquiry. Thus, we designed an open-ended in-depth inquiry about Ohm's law and made students conduct it. To do this, we developed a laboratory activity for students following a standard method of Ohm's…

This laboratory experiment offers a research-style experience designed for senior undergraduate students in a multidisciplinary laboratory setting. The experiment focuses on the synthesis, characterization, and application of a cation-exchange membrane made of COF-SO[subscript 3]Na/PAN for ion separation. By participating in this practical…

Undergraduate-level laboratory experiments that integrate multidisciplinary chemistry concepts into a single activity are very appealing and thought-provoking for chemistry students. Here, we use the oscillating chemical reaction to introduce students to the analytical detection concept. The Belousov-Zhabotinsky reaction is employed as a simple…

A structured series of activities has been designed and implemented to promote analysis and data reporting skills for second-year organic chemistry students. Student report sheets were developed to assist students in reporting necessary data for their compounds. A series of rubrics have been utilized by students to promote metacognition and by…

Learning style (LS), either visual or verbal, has become debatable in the f ield of education vis-à-vis its relation to student success. However, it remains a valuable research theme for improving learning activities in the teaching of highly visual science fields, including biology, physics, and chemistry. Previous studies have primarily focused…

Novice chemists often struggle with the highly visual nature of some chemistry topics. To make visually demanding concepts, such as isomerism and stereochemistry, more accessible to students, chemistry instructors have long recommended the use of molecular model kits as visual aids. However, studies pertaining to student model usage have shown…

Patch-clamp electrophysiological recordings of neuronal activity require a large amount of space and equipment. The technique is difficult to master and not conducive to demonstration to more than a few medical students. Therefore, neurophysiological education is mostly limited to classroom-based pedagogies such as lectures. However, the…

Recent research emphasizes the need for a more sustained interaction of schools with universities and research institutions. For example, informal after-school programs integrated into the school curriculum can provide opportunities for meaningful interaction with researchers in active learning settings. At the physics department of University of…

This paper presents an analysis of cognitive skill levels expressed in high school students' performance using laboratory simulations. We address lower-order cognitive skills (LOCS) and higher-order cognitive skills (HOCS) situations in a virtual simulation activity, in order to identify and underly further discussions about students' reasoning…

Protocol-guided teaching is a student-centered instructional model in which the teacher creates the learning protocol prior to the lesson in order to direct students toward active and autonomous learning. A well-structured learning protocol is essential for the effective application of this instructional paradigm. This article evaluates the…
