Cover: Service-Learning 

Analytical chemistry students participated in service learning by quantifying sucralose and other analytes in water from water-treatment wetlands, as discussed by Emily C. Heider, Domenic Valenti, Ruth L. Long, Amel Garbou, Matthew Rex, and James K. Harper in their article Quantifying Sucralose in a Water-Treatment Wetlands: Service-Learning in the Analytical Chemistry Laboratory. Sucralose, an artificial sweetener, is a potential marker of anthropogenic waste in natural waters. The project engaged students using a real-world application and expanded the students’ analytical repertoire to include sampling strategy, standard addition calibration, solid-phase extraction techniques, liquid chromatography, and mass spectrometry. At the completion of the course, students presented the results in a public seminar. Assessments of the participating students show that they perceived improved self-efficacy while demonstrating comparable content proficiency, relative to students in a conventional analytical chemistry course. For another example of service-learning, see:

A Service-Learning Chemistry Course as a Model To Improve Undergraduate Scientific Communication Skills ~ Stan Najmr, Joanna Chae, Mara L. Greenberg, Cory Bowman, Ira Harkavy, and Jenine R. Maeyer


In this month’s Editorial, Thomas Holme and James Hutchison advocate for A Central Learning Outcome for the Central Science. They argue that ”establishing an overarching learning outcome for chemistry courses presents a flexible approach for embracing the challenge posed by our unique history and catalyzing future contributions to society through the students we educate.”
