Jim Vanides, the program manager for higher education philanthropy at Hewlett Packard has a new blog out on teaching & learning with technology. It's titled "Teaching, Learning, & Technology in Higher Education". The first entry is about using Tablet PCs to gather real-time classroom feedback where the responses are open-ended, such as drawings, rather than the multiple-choice questions that have traditionally been the only choice with existing "clicker" systems.
