Students who experience research as undergraduates tend to remain in science, technology, engineering, and mathematics fields. Since course-based undergraduate research experiences (CUREs) are often expensive to implement, we developed a relatively inexpensive first-semester research course for majors entitled "Freshman Research in…

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…

A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

One challenge for the introductory physics teacher is incorporating calculus techniques into the laboratory setting. It can be difficult to strike a balance between presenting an experimental task for which calculus is essential and making the mathematics accessible to learners who may be apprehensive about applying it. One-dimensional kinematics…

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…

Blended learning combines face-to-face class based and online teaching and learning delivery in order to increase flexibility in how, when, and where students study and learn. The development, integration, and promotion of blended learning in frameworks of curriculum design can optimize the opportunities afforded by information and communication…

We describe a new approach to teaching introductory biology. Our introductory experience for undergraduates is a laboratory course that is entirely inquiry and discovery based. We introduce our students to fundamental concepts in biology in the framework of three multi-week laboratory modules, each of which is an open-ended investigation of a…
