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…

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…

The use of smartphones in experimental physics is by now widely accepted and documented. PASCO scientific's smart cart, in combination with student-owned smartphones and free apps, has opened up a new universe of low-cost experiments that have traditionally required cumbersome and expensive equipment. In this paper we demonstrate the simplicity,…

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…

The majority of undergraduates own a smartphone, yet fewer than half view it as a valuable learning technology. Consequently, a digital laboratory notebook (DLN) was developed for an upper-division undergraduate biochemistry laboratory course using the free mobile application Evernote. The cloud-based DLN capitalized on the unique features of…

Social media are a highly visible factor in the daily lives of our students. Why should teachers not take advantage of this and develop teaching and learning materials that use the designs found in such media to contextualise science learning? This article suggests some ideas for creating lab instructions using social media design as an innovative…

Mobile devices have become a popular form of education technology, but little attention has been paid to the use of their sensors for data collection and analysis. This article describes some of the benefits of using mobile devices this way and presents five challenges to help students overcome common misconceptions about force and motion. The…

When dissolving copper in nitric acid, copper(II) ions produce a blue-colored solution. It is possible to determine the concentration of copper(II) ions, focusing on the hue of the color, using a smartphone camera. A free app can be used to measure the hue of the solution, and with the help of standard copper(II) solutions, one can graph a…

Describes how a traditional neurophysiology laboratory has been computerized and how students work with digitizing on-line data. Points out advantages of computerization, including the speed, accuracy, and reliability in the acquisition, reduction, and analysis of data. Also describes four generic computer programs tailored to the particular…

Supplies short descriptions of several computer applications in the college science classroom and laboratory, including: applications; interfacing and data collection with the TRS-80; programs for activity corrections in acid/base and precipitation titration curve calculations; computer-assisted data analysis of enzyme kinetics; and microcomputer…

Microcomputer-based laboratories (MBLs) refer to a laboratory where a microcomputer gathers and displays data directly from the environment. Program listings for a response timer (using game paddles) to illustrate the nature of MBLs are presented. (JN)

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.…

Presents Part II of a description of a computer-oriented course on process control which has been offered at the University of Wisconsin for undergraduate students. Lecture topics and laboratory experiments are also included. (HM)

CHEMPAC, a computer-based chemistry course developed for high school students, bridges the gap between textbook and laboratory to provide greater quantitative accuracy to laboratory experiments. This course and experiments (involving pH) illustrating the CHEMPAC approach are provided. (JN)
