Priya Yadav; Harshita Laddha; Madhu Agarwal; Ragini Gupta – Journal of Chemical Education, 2022
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…

Jinglin Fu; Anthony Monte Carlo; Doris Zheng – Journal of Chemical Education, 2025
The COVID-19 pandemic has accelerated the shift from traditional in-person teaching to remote and online learning, necessitating a more adaptable educational platform to serve the diverse needs of students. Transforming hands-on "wet lab" activities into virtual "dry lab" exercises can promote a more accessible and flexible…

Basics of Fourier Transform Applied to NMR Spectroscopy: An Interactive Open-Source Web Application
Peer reviewed Peer reviewed
Direct linkDirect link
Esvan, Yannick J.; Zeinyeh, Wael – Journal of Chemical Education, 2020
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…

A Simple Experimental Setup for Teaching Additive Colors with Arduino
Peer reviewed Peer reviewed

Carvalho, Paulo Simeão; Hahn, Marcelo – Physics Teacher, 2016
The result of additive colors is always fascinating to young students. When we teach this topic to 14- to 16-year-old students, they do not usually notice we use maximum light quantities of red (R), green (G), and blue (B) to obtain yellow, magenta, and cyan colors in order to build the well-known additive color diagram of Fig. 1. But how about…

Falloon, Garry – Journal of Science Education and Technology, 2017
Considerable work over many years has explored the contribution technology can make to science learning, at all levels of education. In the school sector, historically this has focused on the use of fixed, desktop-based or semi-mobile laptop systems for purposes such as experiment data collection or analysis, or as a means of engaging or…
