A continuous effort within an undergraduate university setting is to improve students' learning outcomes and thus improve students' attitudes about a particular field of study. This is undoubtedly relevant within a chemistry laboratory. This paper reports the results of an effort to introduce a problem-based learning strategy into the analytical…

In this laboratory experiment, high school students are challenged to prepare a six-layered chemical "rainbow" in a test tube. Students start with six unknown, colorless liquids and six pigments ranging from violet to red. The experiment is problem based and forces the students to apply their knowledge of solubility and density and combine it with…

Clickers are electronic response devices with which a student can remotely submit responses to questions or problems posed by a teacher. The problems are typically true-false or multiple-choice questions, but can also include numerical problems. Clicker devices are particularly popular in large-enrollment introductory science, technology,…
