Tools By Laura Turner The following web2.0 sites would be useful for science educators at the high school and middle school level. Some would also be appropriate for higher elementary grade levels. There are many new ‘tools’ or websites that take advantage of the higher speed and bandwidth of today’s Internet. Web 1.0 tools/websites were text based and web2.0 tools/websites are designed for full-motion video, 3D animations and are generally interactive in some manner. Web 2.0 can also be described as the second round of new technology development and adoption. Web 2.0 teaching tools to enhance education and learning — Edjudo 3D Projects Alice – Alice is an innovative 3D programming environment (free) Blender – Excellent open source 3D content creation suite (free, must install) PhotoSynth – A Microsoft web application that takes your photos, mashes them together and recreates a 3D scene out of them that anyone can view and move around in.

HPS 0410 Einstein for Everyone Title page, Preface and Table of Contents for Einstein for Everyone Introduction: the Questions Special Relativity Special Relativity: the Principles Special Relativity: Clocks and Rods Video and Podcasts: Events by Category Marc Davis A description of modern astronomy with emphasis on the structure and evolution of stars, galaxies, and the Universe. Jennifer A. Doudna, John G. Forte, Michael Meighan, Robert L. Fischer SBG Success Part 2 (Grading System) Physics & Physical Science Demos, Labs, & Projects for High School Teachers With weekly quizzes and so many additional concept quizzes, I was worried about the time it would take to grade everything. I’ve been pleasantly surprised at how quickly I can get through a set of quizzes, it’s quick because I don’t worry about partial credit. Each problem gets one of four grades: 4 – The problem is done correctly, no errors3 – The student understands the underlying concept but made at least one or more mistakes2 – The student is starting to understand the concept, but clearly isn’t there yet1 – No real understanding0 – No attempt at a solution
