We just wanted to give a heads up that Schoology will be undergoing some changes in its appearance to go along with theming that is related to its parent company PowerSchool. At some point in the near future you will see that the color scheme will change to go with its new branding. In addition, the icons for materials that you can add to your courses will change (see a preview screenshot below).
Overall, we are under the impression that these changes that are being made by Schoology are cosmetic. If you notice that anything does not work the way it should or if you have any other questions regarding these changes, please place a ticket or schedule time to meet with an Instructional Technology Specialist!
