Eric.ed.gov – Active Learning Institute: Energizing Science and Math Education. A Compilation of Lesson Plans.

Posted on by Troels Gannerup Christensen - Læst 6 gange

eric.ed.gov har udgivet: The middle school and high school lessons featured in this collection were crafted by science and math teachers who participated in a week-long seminar sponsored by the Eisenhower Professional Development Program administered by the Ohio Board of Regents. The lessons showcase a variety of active learning strategies from using hands-on, low-tech approaches to integrating high-tech, cutting-edge resources. Lesson topics include: (1) Investigating Energy Sources; (2) Probing the World of Energy and Its Conservation; (3) Fish Out of Water–Man Out of Land; (4) Are You Listening? (Noise Pollution); (5) Countdown to Population Explosion; (6) Hazardous Chemicals in Your Home!; (7) Water, Water Everywhere–How Much Is There to Drink?; (8) Water, Water Everywhere–But Not a Drop to Drink; (9) A Multi-Level Water Study; (10) Futuristic Fuel from Water; and… Continue Reading →

Eric.ed.gov – Environmental Systems Simulations for Carbon, Energy, Nitrogen, Water, and Watersheds: Design Principles and Pilot Testing

Posted on by Troels Gannerup Christensen - Læst 26 gange

eric.ed.gov har udgivet: Guided by the Next Generation Science Standards and elements of problem-based learning, four human-environment systems simulations are described in brief–carbon, energy, water, and watershed–and a fifth simulation on nitrogen is described in more depth. These science, technology, engineering, and math (STEM) education simulations illustrate design principles that make them engaging to students, such as dynamic visual environments that are controlled by the user and immediate visual feedback to user actions taken. The simulations are contextualized in real-world natural resources management challenges involving biogeochemical cycles, such as Gulf of Mexico hypoxia, which provide an opportunity to “win the game,” while the introduction of complexity in steps provides scaffolding. Pretest versus posttest results indicate a substantial and statistically significant improvement in learning outcomes resulting from using the nitrogen simulation,… Continue Reading →
