A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

Although science is a creative endeavor (NRC 1996, p. 46), many students think they are not encouraged--or even allowed--to be creative in the laboratory. When students think there is only one correct way to do a lab, their creativity is inhibited. Park and Seung (2008) argue for the importance of creativity in science classrooms and for the…

This article describes an alternative way of testing--a performance assessment--that is different both in process and goals from typical tests, but closer to what teachers believe assessment should be. Teachers who have helped to create, refine, and use this new generation of tests find them valuable because they measure the skills and concepts…

Describes experiences, or "lab puzzles," which will help students develop problem-solving skills in a laboratory setting. Outlines procedures for developing techniques, setting boundaries, and finding the number of molecules of water in Lake Erie. (RT)

Explains how computer and game port interfacing reduces the time required for data collection and organization and also stimulates student interest in science laboratory exercises. Illustrates this approach through a description of a population-variation lab. Includes diagrams for the construction of the interface box. (ML)
