The external tool in Moodle enables users to integrate external publishing tools directly into their Moodle course. Many publisher tools provide materials and interactive learning exercises that are different from Moodle's own resources and activities. The external tool that Moodle offers allows for instructors to link to these activities from within their Moodle course page and have grades sent back into the Moodle Gradebook. Currently, the tools that are configured in Moodle include, but are not limited to, Cengage, McGraw-Hill, and Pearson.
Please visit the External Tool Document for more information on how to utilize this tool in your Moodle course.
The Respondus Test Bank Network can help you connect with your textbook publisher to determine if they have a testbank that can be downloaded directly into your Respondus 4.0 quiz-building software.
