Teaching Notes and Tips

This activity uses a customized data set made from the 1990 Census and guides students through data manipulation using WebCHIP software found at DataCounts!. To open WebCHIP with the dataset for the activity, please see instructions and links in the exercise documents under teaching materials. For more information on how to use WebCHIP, see the How To section on DataCounts! Note to instructor: This module will require several class periods to work through. You should use your discretion to allocate parts of it to whole class discussion, group work, individual work in class, and written homework. You may want to supplement the data analysis and discussion with relevant readings. Before giving the module to your students, you will want to edit out the sections labeled “for instructor only.” I would enjoy learning about your experiences using this module and suggestions for enhancing it.
