This is a simple presentation that introduces people to the concept of a CMS. The slidedeck precedes two days of establish a course presence in Moodle for Glenbrook South High School Teachers. The course presence is only one component of a multidimensional learning space (MDLS) that supports the interactions in the brick and mortar school. The MDLS is constructed of a course space for teachers, a student space for content creation, hosted in Google Apps, and then a knowledge commons, where other groups associated with the education of students (library, guidance, etc)at GBS can contribute learning objects that support the other two components.
