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…

If you've ever asked yourself whether problem-based learning (PBL) can bring new life to both your teaching and your students' learning, here's your answer: Yes. This all-in-one guide will help you engage your students in scenarios that represent real-world science in all its messy, thought-provoking glory. The scenarios will prompt K-12 students…

"Problem-Based Learning in the Physical Science Classroom, K-12" will help your students truly understand concepts such as motion, energy, and magnetism in true-to-life contexts. The book offers a comprehensive description of why, how, and when to implement problem-based learning (PBL) in your curriculum. Its 14 developmentally…

Encouraging students to reason with quantitative relationships can help them develop, understand, and explore mathematical models of real-world phenomena. Through two examples--modeling the motion of a speeding car and the growth of a Jactus plant--this article describes how teachers can use six practical tips to help students develop quantitative…

In our science for non-science majors course "21st Century Physics," we investigate modern "Hubble plots" (plots of velocity versus distance for deep space objects) in order to discuss the Big Bang, dark matter, and dark energy. There are two potential challenges that our students face when encountering these topics for the…

Describes the design of a biochemistry course that uses problem-based learning. Provides opportunities for students to question, dispute, confirm, and disconfirm their understanding of basic concepts. Emphasizes self-correction through dialogue. Topics covered include amino acids, metabolic pathways and inherited disease, proteins, enzymes and…
