The Fourier transformation (FT) is a mathematical process frequently encountered by chemistry students. However, it remains an automated background process perceived by many students as difficult to understand. In this paper we present a simple open-source web application, which can help students to understand the basics of the FT applied to…

This paper provides two demonstrations of how Augmented Reality (AR), which is the projection of virtual information onto a real-world object, can be applied in the classroom and in the laboratory. Using only a smart phone and the free HP Reveal app, content rich AR notecards were prepared. The physical notecards are based on Organic Chemistry I…

A smartphone-based digital imaging method has been successfully introduced in an undergraduate laboratory class to quantify fluoride ions in water. Students first synthesized the chemosensor (E)-2-(1-(6-nitro-2-oxo-2H-chromen-3-yl)ethylidene)-N-phenylhydrazine-1-carbothioamide (CT) via an eco-friendly and green microwave-assisted protocol and…

An online virtual escape-room game was created using the Google Forms survey app for an undergraduate chemistry lab class. Zoom video conferencing service was used to make the activity a collaborative learning experience. The theme was an escape from an abandoned chocolate factory, and the students solved problems to move to the next section or…

In general chemistry laboratories, students learn practical laboratory skills through hands-on activities and are exposed to new scientific instruments. However, these instruments are often viewed as black boxes for various reasons, where students do not know how to use them or what the instruments are capable of. This tendency is likely to induce…

Building on previous success with a digital pipet badge, an evidence-centered design approach was used to develop new digital badges for measuring the volume of liquids with a buret and making a solution in a volumetric flask. These badges were implemented and assessed in two general chemistry courses. To earn the badges, students created videos…

In this study, smartphone was used to alter the traditional procedure by involving students in active learning experiences prior to the laboratory meeting. The researcher surveyed students' view on the effect of using smartphone to enhance learning in the general physics laboratory. The use of smartphone was evaluated by having 120 students who…

Safety procedures used by Department of Chemistry at the University of Akron are discussed. These include policy that no chemicals are stored in the teaching laboratories. Instead, dispensing stockrooms are used to service the laboratories. Other aspects discussed include ventilation procedures and development of microprocessor use in stockrooms.…

Describes the conversion of a laboratory and change in course content in a chemical engineering curriculum. Lists laboratory experiments and computer programs used in the course. Discusses difficulties during the laboratory conversion and future plans for the course. (YP)

Explains a method for keeping track of chemicals, supplies, and equipment by using a computer. Describes stockroom personnel, department needs, the physical plant, restocking procedures, file setup, and effectiveness of the program. Examples of sample inventory forms are included. (RT)

Experiments are designed with application to phenomena of the real world for use in a third-quarter introductory college physics course in wave motion, sound, and light. The computer is used to process and analyze experimental data and to extend experimental observations through simulation. (Author/TS)

Describes material used in a first semester introductory physics laboratory for nonscience majors. The computer is used for data manipulation and in some cases, computer programs allow simulation of experiments with the possibility of altering values of parameters or experimental details. (Author/TS)

Explains two approaches to the automatic arrest of a potentiometric titration. (SA)

Describes development of microcomputer-controlled gamma scintillation spectrometer and chromatographic data analyzer, including design and construction of interface electronics and production of software. Includes diagrams of electric circuits and project evaluation indicating that both instruments functioned as intended. (JN)
