Teachers TryScience is a web site for teachers. This site provides free and engaging lessons, along with teaching strategies and resources, which are designed to spark students’ interest in science, technology, engineering and math (STEM). What’s more, the site features collaboration tools to enable teachers to discuss and share effective instructional practices. Teachers TryScience is a collaborative effort between the New York Hall of Science, IBM Corporation and teachengineering.org. It was developed to bring best practices in design-based learning to schools. Design-based learning gives everyone the flexibility to facilitate and enable students to synthesize skills from a variety of disciplines and integrate them into learning activities. For example, to solve a problem in environmental science, students might need to employ physics, chemistry and earth science concepts and skills. Such a STEM integrated lesson will: stimulate critical thinking and apply inquiry skills; apply mathematical and technological solutions to engineering problems; may apply science concepts from more than one science discipline; recognize that more than one approach to problem solving may be valid; may require alternative measures of assessment; recognize that different students approach a problem or topic from different entry points; recognize that prior knowledge may determine the approach the student takes to the problem; and that sometimes the research question simply generates many more questions.
