National Science Learning Network Blog Khanacademy Simple Physics Demos | Science Blogs This past weekend, the Louisiana Section of the AAPT participated in the joint NSTA-AAPT Physics day. The most popular presentation was the “really simple and cheap physics demos”. Lots of participants asked about the demo details. Although I posted a simple list of the demos, I figured it wouldn’t hurt to give slightly more detail. So, here you go.A note about the demos. Why did I choose these particular demos? This is an oldie…well, its an oldie where I come from. Interactive Lecture Demonstrations in Economics The Interactive Lecture Demonstration is designed to help students learning core concepts in economics using a classroom activity that may be an experiment, a survey, a simulation or an analysis of secondary data. The activity creates a motivation for students to learn economic analysis presented in a follow-up lecture. The Interactive Lecture Demonstration differs from most classroom activities such as economic experiments in that it follows a framework in which students: Predict an outcome Experience the demonstration Reflect on what they learned Why use Interactive Lecture Demonstrations? Interactive Lecture Demonstrations are an effective way to help students learn fundamental economic concepts because: In economics, many concepts are counter-intuitive or defined in a manner different from their colloquial usage. How to use Interactive Lecture Demonstrations in economics Which courses? Interactive Lecture Demonstrations are used most often in principles courses. Challenges and insights
