Faculty members are expected to limit class activities to school-sanctioned online services (including social media and blogs). New social media tools and features that may or may not be appropriate for course use are being continually introduced. Any online services or social media tool that will be used in the classroom or that will be recommended to, assigned to, or otherwise used as part of the instruction to students must be approved in writing by the HOS, the headmaster or division director. This approval must be obtained prior to using the tool with students.
