For the past several decades, high-enrollment undergraduate chemistry laboratory experiences have favored traditional approaches involving disparate daily experiments with optimized protocols provided to students. This model often results in poor learning outcomes and low student engagement, and it lacks any attention to scientific inquiry. Here,…

Decreased funding for middle and high school education has resulted in reduced classroom time, which, when coupled with an increased focus on standardized testing, has decreased the exposure of many middle school students to hands-on science education. To help address these challenges, we developed an integrated outreach program, spanning grades…

We selected diabetes mellitus for this laboratory exercise to provide students with an explicit model for scientific research concerning the association between the R230C polymorphism and susceptibility to type 2 diabetes mellitus, which is highly prevalent in the Mexican population. We used a collaborative project-based learning to engage…

Three undergraduate students functioned as teaching assistants in unit ops lab for their senior project, which included developing a purchased size exclusion chromatography experiment, supervising the running of this experiment, and assisting the junior students with their calculations. They also read the reports, graded them, and commented on…

This article describes a discovery experiment for general chemistry and organic chemistry labs. Although the pinacol rearrangement has been employed in undergraduate organic laboratories before, in this application organic chemistry students act as mentors to students of general chemistry. Students work together using distillation--a new technique…

The two goals of this program were to increase the number of classroom teachers using the lab and to increase the amount of time that the science lab was used. The solution strategy chosen was a combination of peer tutoring, orientation presentations, small group discovery experiments and activities, and individual science experiment stations. The…
