The plate and frame filtration experiment is one of the essential experiments performed by undergraduate students during their practical education. While this experiment often relies on the conventional manual recording of data and calculation, there are frequent problems with data collection because capturing transient data of filtrate volume and…

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…

As part of COVID-19 preparedness, a student-developed, Android-based app was used as a pre-laboratory learning aid for a molecular modeling laboratory in a first-year general chemistry course. A worksheet activity with trigger codes and questions related to spatial features of transition metal complexes was designed. Using the Transition Metal…

The educational game Interactions 500 was extensively used remotely during the COVID-19 Pandemic as an activity at the Federal University of Ceará (Brazil) to help students review intermolecular forces. In the postpandemic years, the game was also used face-to-face in the classroom. However, Apple Store and Google Play Store removed it from their…

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…

"Is this solution pink enough?" is a persistent question when it comes to phenolphthalein-based titration experiments, one that budding, novice scientists often ask their instructors. Lab instructors usually answer the inquiry with remarks like, "Looks like you have overshot the end point", "Perhaps you should check the…

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…

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…

Explain Everything is an interactive, user-friendly, and easily accessible app for mobile devices. The interactive app-based teaching methods discussed here can be adopted in any STEM or non-STEM course. This app allows instructors to take advantage of both the chalkboard and PowerPoint slides on a single platform, create videos for lecture…

Mobile technology is increasingly prevalent in higher education. Chemistry-related software applications (apps) on touchscreen computers are emerging as a popular platform in many areas, including in the chemistry classroom. In this work, a new game-based app designed for hand-held and portable touch-controlled devices is presented. Chirality-2…

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…

Discusses computer simulation which focus students' attention on logical steps involved in qualitative analyses. (SK)

Discusses using an Apple II microcomputer as a Laboratory Data System (LDS) for the analysis of data fed from a UV-Visible Spectrophotometer. (SK)
