Fatma Yaman; Brian Hand – International Journal of Science Education, 2024
This study aims to investigate the relationship between written and oral reasoning in an undergraduate chemistry laboratory course as part of an argument-based inquiry approach, which is also a generative learning environment, known as the Science Writing Heuristic (SWH). The study employed the data-transformation variant of convergent design of…

This study introduces a modernized approach to classical volumetric titrations for the undergraduate chemistry curriculum. Leveraging smartphones and digital top-loading balances, we performed mass-based titrations and determined end points using digital color measurements. Our aim was to make classical wet chemistry more accessible and engaging…

Kok, Karol; Boczianowski, Franz – Physics Teacher, 2021
Science labs should promote reasoning that resembles the work that scientists do. However, this is often not the case. We present a lab in which students strive to find out which of two models best describes a physics experiment. The quantification of measurement uncertainties--another topic that is often neglected in high school…

Mondaca, Elias; Wright, Keenan; Chavarria, Nicole; Fahrenkrug, Eli – Journal of Chemical Education, 2021
Lab-on-a-chip devices are a critical and emerging chemical technology. New pedagogical tactics that effectively capture both analytical chemistry concepts along with the design elements unique to these devices are necessary for effective integration in the undergraduate chemistry curriculum. This article develops a design-based learning laboratory…

Chukwuneke, Chikaodili E.; Madu, Joshua O.; Agboola, Bolade O. – Journal of Chemical Education, 2021
Trace metals when present in crude oil or fuels are of economic significance in refining and to the combustion engines that use them. Herein, we develop a laboratory activity that trains students on how to analyze crude oil samples for ash and trace metal content while giving them the opportunity to acquire skills needed as a quality control…

Greenslade, Thomas B., Jr. – Physics Teacher, 2021
Look along the shelves holding your laboratory apparatus and into the demo-prep room, and you will find apparatus by "Cenco" and "The Central Scientific Company" sharing space with your new PASCO equipment. At the 1989 AAPT meeting in San Luis Obispo I was asked to talk about Cenco in honor of one of its long-term employers and…

Nyutu, Eva N.; Cobern, William W.; Pleasants, Brandy A.-S. – Research in Science Education, 2022
Science instructors assume that they have created their laboratory curriculum in such a way as to reflect an ideal science instructional laboratory, but students may not recognize this. A recent study used the Student Perceptions of the College Instructional Laboratory Survey (SPCILS) to examine students' perceptions of their science instructional…
