Students often confuse the functional differences between motion "transmission" and "transformation" systems. Students find it difficult to conceptualize differences between the specific systems. In this article, the author describes a technology and engineering unit that incorporates problem-based learning (PBL) to assist…

Studies show that overall seafood consumption in the United States is rising (Agriculture and Agri-Food Canada 2012). Other research estimates that as much as 40% of the seafood caught worldwide is discarded, while countless sharks, whales, dolphins, birds, sea turtles, and other animals are unintentionally killed or injured by fishing gear…

Focuses on problem-based learning (PBL). Explains ill-defined problems of PBL and compares PBL with the typical problem solving approach. Lists 10 steps to involve students in constructing understanding for use with PBL. (YDS)

Uses a hypothetical ecology problem in which students need to apply problem based learning for a town government. Explains how to evaluate student results. (YDS)

Explains the process of student and teacher collaboration on a project to develop a faster electrolysis mechanism. Provides a good example of the problem-based approach to science instruction and curriculum. (DDR)

Presents an instructional framework for real-world, problem-based studies that can be used in a variety of settings. Discusses background knowledge, problem exposition, data collection and analysis, data synthesis and solution presentation, and career information. (JRH)
