 LTI External Tool improvements in Moodle 4.3 In Moodle 4.3 teachers have a page for managing LTI External Tools in their course and they can choose which tools are shown in the activity chooser. The activity type external tool is no longer available. Adding an LTI External Tool activity is easier now with a simplified form and site administrators can restrict the use of a tool to courses in specific categories only. In Moodle 4.3 teachers can add and manage LTI External Tools from a new location from more LTI External Tools. This page lists tools added at site level by a site administrator and any tools added at course level. Site level tools have a padlock in the actions column as teachers can't edit or delete them. Teacher Mr Wilson is going to add a tool. He clicks the add tool button, fills in the form and saves the changes. The tool is then listed on the LTI External Tools page and shown in the activity chooser. When we go to the course page with edit mode enabled and click to access the activity chooser, we see that the activity type external tool is no longer available. Instead we see tools from the LTI External Tools page which are set to show in the activity chooser. Our teacher selects a tool, gives it a name and saves changes. Back on the LTI External Tools page we see that this tool now has a usage count of one. If a teacher doesn't want to use it again in the course, they can set it to not show in the activity chooser. A further LTI External Tool improvement in 4.3 is the option for site administrators to restrict the use of a tool to courses in specific categories only. From plugins, external tool, manage tools, our admin clicks on a tool she has added. There is a new section, restrict to category, where she can select one or more course categories and this tool will then be listed in the LTI External Tools page of courses in these categories only ready for teachers to add to their courses. To summarise, in Moodle 4.3 teachers have a new page for managing LTI External Tools in their course, allowing them to choose which tools are shown in the activity chooser. The external tool activity type is no longer available. A simplified form makes adding tools easier and admins can restrict the use of a tool to courses in specific categories only.
