Instructors optimize the use of class time for quantity and depth of learning. Technology has opened new opportunities in these respects. The technique reported on here, In-class Common-reporting Workshops (INCREWs) consist of teams of up to three students tackling a creative class-relevant problem and displaying their evolving results on a common, projected spreadsheet format in real time. We report on surveys, which have shown a positive reception for INCREWs.
