This is a great company as they use teachers to write online lesson plans. I am working on high school physics. This is not my expertise but the experience has me digging into my physics and physics creativity.
Coming up with experiments to show the basic concepts that physics covers is important. My ideas are based on a more conceptual approach instead of all the math problems. I have developed some great physics resource sites and have increased my knowledge about the major theories on the principals of how physics affects our world.
developing modern activities that the student can develop their observation, math, graphing skills and apply them to theri reality is important .
