This course will provide an introduction and orientation to the GLOBE web site, particularly well-suited for teachers and informal science educators. Environmental data collected by science agencies across the GLOBE as well as at GLOBE schools can be retrieved, and opportunities to use GLOBE protocols, learning activities, and student research collaborations are all explored in this tutorial. Assessment will include some examples from the mapping and search engines on the web site, and participants will be asked to download sample data. Prerequisite: some knowledge of computer spreadsheets and how they function and their use as aids in data analysis. Instruction is completely online using a learning management system, and the GLOBE web site. This course, or prior experience in the GLOBE program is required for all remaining units.
