An article describing the development, testing, and evaluation of a new guided-inquiry experiment for UBC’s second-year analytical chemistry course (CHEM 211) has just been published in the Journal of Chemical Education!
The CHEM 211 labs have seen many exciting changes over the past few years, including the introduction of several guided-inquiry experiments in which students research and develop their own designs and procedures for tackling an analytical problem. In the “Build your own Photometer” experiment, students research fundamental concepts in spectrophotometry, then apply their findings to design, build, and test a submersible photometer that can be used to monitor colour-change reactions such as titrations. You can read all about the experiment here.
This experiment and article are the products of a collaboration between Instructional and Research Faculty, students, and the CWSEI. Dr. José Rodríguez Núñez (CHEM 211 lab director) and Dr. Russ Algar (CHEM 211 instructor and research faculty) developed the concept and basic plan, Jessie Wang (a UBC chemistry undergraduate) developed and refined the procedures, and I interviewed and surveyed students in order to evaluate the success of the experiment. I’m very proud of the resulting article, and of the fantastic collaboration that made it happen.
