The OER Commons LTI Tool is currently incompatible with Safari.  We recommend using the LTI with Chrome or Firefox while we work to fix this. We apologize for the inconvenience.

Overview

Content Selection

The LTI tool allows any educator to browse and embed media objects alongside other content within assignments, or select content which comprises entire modules, lessons, or units. All users are able to search content added to OER Commons Collections. Additionally, users can also browse or search content from Group Shared Folders and personal My Items libraries, if that content has been configured and made available. 


Authentication and Account Provisioning

The tool provides automated authentication and new account provisioning, providing users with an "SSO like" experience. The LTI key/secret pair can also be configured to automatically add new users to an OER Commons Group. 

LTI Tool Preview Images

Some basic preview images of the tool have been included below. More details about using the LTI tool are available in the "Using the LTI tool" section of this guide.
