Problem-based learning (PBL) fosters both content knowledge and content understanding, improves critical and process thinking skills, and promotes peer-to-peer learning, leadership, and teamwork (Hmelo-Silver 2004). Instructors support the PBL process by guiding students through activities that challenge their current knowledge and understanding…

Scientists and other professionals across the globe require employees to collaborate, think critically, and solve problems effectively. To this end, the "Next Generation Science Standards" (NGSS) have a vision of ensuring that through inquiry, collaboration, and evidence-based instruction, students will have the necessary skills to be…

"A Framework for K-12 Science Education" identifies eight science and engineering practices for K-12 classrooms. These practices, along with core ideas and crosscutting concepts, define the nation's learning goals for science. An important advance from earlier standards (AAAS 1993, NRC 1996), these practices are clearly identified "not" as…

Movie clips can provide data for content-rich problem solving, show students exotic phenomena, allow them to apply science concepts in a new setting, and foster connections between science and the humanities. Though the latest release will have the advantage of pop-culture currency, films old enough to be released on DVD give teachers more…

Teacher research--often called "action research"--is an intentional and systematic inquiry into one's own classroom practice with the goal of improved student learning (Cochran-Smith and Lytle 1993). In this article, the authors present a teacher research project undertaken to improve student understanding of the gas laws in a high…

A Drinking Bird toy is used to stimulate scientific questioning and problem solving. Suggestions are given for using the bird to explore scientific concepts including evaporation, work, systems, density and dynamic equilibrium. 32 questions you can use to stimulate student investigations are listed. (AJ)

Describes a lesson that utilized inquiry to teach the students a scientific concept and to emphasize the fact that they shouldn't jump to conclusions. (LS)

Incorporates some ideas from a book by Galileo into a problem-solving format that challenges students. (LS)

Provides guidelines for classroom discussions of bioethical issues. Equipped with an ethical reasoning model, teachers can help to prepare students to make responsible decisions about science-related issues. (ZWH)

Describes a class activity where individual students ask the teacher "yes and no" questions to find the amount of force the bicep uses to lift a 1 kilogram mass. (PR)

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 a program where teams of fifth graders and high school junior and senior physics students work together to explore physical science principles and create a student-constructed exploratorium. Incorporates and synthesizes scientific inquiry, hands-on activities, and creative and critical problem-solving approaches in a motivating and fun…

Describes a three-week environmental minicourse in a general chemistry class. The minicourse consisted of two distinct phases, a one-week introduction to environmental chemistry and a two-week project involving a particular environmental problem. (PR)

Describes two software programs for the Apple II series and TRS-80 Models III and IV: (1) "Personal Energy Inventory" (grades 9-12, records and manages data, not considered user friendly); (2) "Energy Conservation" (grades 7-12, aids in converting and problem solving, uses drill and practice). (MVL)
