Direct linkWellhofer, Larissa; Luhken, Arnim – Journal of Chemical Education, 2022
Problem-based learning (PBL) is an acclaimed educational concept for laboratory teaching in chemistry, which significantly affects learner motivation. A central aim of PBL is to overcome educational problems with "cook-book" laboratories. For example, when students receive experimental instructions and apply the instructions similar to…

Shannon L. W. Accettone; Cassandra DeFrancesco; Lori Van Belle; Joel Smith; Erin Giroux – Journal of Chemical Education, 2022
The ability of students to perform quantitative analysis is a fundamental aspect of analytical chemistry courses and laboratories. In this laboratory experiment, students quantitatively analyze both liquid and solid samples through the use of internal standard calibration and ATR-FTIR spectroscopy. Using a problem-based approach to selecting their…

Ong, Jun-Yang; Chan, Shang-Ce; Hoang, Truong-Giang – Journal of Chemical Education, 2018
A Sonogashira experiment was transformed into a problem-based learning platform for third-year undergraduate students. Given a target that could be synthesized in a single step, students worked in groups to investigate which method was the best for large-scale production. Through this practical scenario, students learn to conduct a literature…

Saloranta, Tiina; Lo¨nnqvist, Jan-Erik; Eklund, Patrik C. – Journal of Chemical Education, 2016
In our upper-level undergraduate laboratory course in organic chemistry we focus on a research-oriented task in a context-based and problem-based learning approach. The course starts with a preliminary training period where the students learn how to safely and independently perform synthesis and purification procedures and to operate the most…

Jensen, Mark B. – Journal of Chemical Education, 2015
An instrumentation-based laboratory curriculum combining traditional unknown analyses with student-designed projects has been developed for an introductory analytical chemistry course. In the first half of the course, students develop laboratory skills and instrumental proficiency by rotating through six different instruments performing…

Saslow Gomez, Sarah A.; Faurie-Wisniewski, Danielle; Parsa, Arlen; Spitz, Jeff; Spitz, Jennifer Amdur; Loeb, Nancy C.; Geiger, Franz M. – Journal of Chemical Education, 2015
The classroom exercise outlined here is a self-directed assignment that connects students to the environmental contamination problem surrounding the DePue Superfund site. By connecting chemistry knowledge gained in the classroom with a real-world problem, students are encouraged to personally connect with the problem while simultaneously…
