These are the learning Barbara Reisner, James Madison University - January 25, 2015 - 8:27am These are the learning objects contributed to VIPEr's first community challenge where community members were asked to contribute problems on atomic orbitals, electron configurations, and periodic trends.Two in class activities were also contributed. As soon as the problem set questions have all been reviewed and posted, we'll get those added to the list because they're a great place from which to mine questions.Thanks to everyone who participated! This is a great collection of Anne Bentley, Lewis & Clark College - January 28, 2015 - 1:56pm This is a great collection of problems from which to browse for exam content. I modified three VIPEr problems and included them on the final exam in my inorganic course last spring. At the end of the exam, I included three brief statements along the lines of "Problem x was modified from work created by Jane Doe, Some College for the Virtual Inorganic Pedagogical Electronic Resource (VIPEr) and licensed under the Creative Commons Attribution License 3.0." Is that a good approach to make sure I'm giving credit properly? This is so cool. Go VIPEr Joanne Stewart, Hope College - January 29, 2015 - 1:41pm This is so cool. Go VIPEr community.You rock!
