|
| == Description ==
| | [[es:Proveedor LTI]] |
| | |
| === About IMS LTI ===
| |
| | |
| According to IMS ([http://www.imsglobal.org]):
| |
| | |
| ''IMS is developing '''Learning Tools Interoperability (LTI)''' to allow remote tools and content to be integrated into a Learning Management System (LMS).''
| |
| | |
| === About this plugin ===
| |
| | |
| This is a local plugin for making Moodle a LTI provider tool.
| |
| | |
| It can be use to provide access to full courses or activities from remote systems (other Moodle installations, Sakai, any LMS LTI consumer compliant)
| |
| | |
| Please note that since Moodle 2.2 there is a core activity plugin called "External tool" that is a LTI consumer.
| |
| | |
| === Why this plugin ===
| |
| | |
| This plugin allow remote systems users (LTI consumers) access to Moodle courses or Moodle activities inside a course.
| |
| | |
| Moodle (version 2.2 and onwards) is a LTI consumer tool also.
| |
| | |
| You can use this plugin to share activities and courses between Moodle installations without configuring a Moodle network.
| |
| | |
| You can also share activities and courses with other LTI consumer tools like Sakai
| |
| | |
| You have a detailed view of this plugin possibilities in [http://www.somerandomthoughts.com/blog/2012/01/08/review-lti-provider-for-moodle-2-2/ this post by Gavin Henrik]
| |
| | |
| == Main feautres ==
| |
| | |
| Provide access to full courses or single activities.
| |
| | |
| Change the navigation block of a course or activity for displaying information and links only regarding to your current course.
| |
| | |
| Send backs course or activity final grades to the LTI consumer tool
| |
| | |
| Modify the course or activity page for hiding the header, footer and left or right blocks
| |
| | |
| == Plugin version 2.3 and above features ==
| |
| | |
| === The plugin settings link is displayed in the settings block, instead the course one ===
| |
| | |
| === Several new settings for control different features of the plugin: ===
| |
| - How the user profile is updated
| |
| - Default authentication method
| |
| - Format of the course shortname, fullname and idnumber (using LTI variables)
| |
| - Roles allowed to create new contexts
| |
| - Roles allowed to create new resources
| |
| | |
| === The remote tool can be opened using the context_id ===
| |
| | |
| The tool can be opened using also the context_id instead the current internal Moodle id
| |
| | |
| === Support for context memberships service ===
| |
| | |
| See http://developers.imsglobal.org/ext_membership.html
| |
| | |
| === LTI custom parameters to force settings on SSO ===
| |
| | |
| See https://tracker.moodle.org/browse/CONTRIB-4502
| |
| | |
| === Service for context (course) creation, using other courses as template ===
| |
| | |
| Service URL local/ltiprovider/services.php
| |
| | |
| Custom parameters:
| |
| | |
| custom_service = create_context
| |
| | |
| custom_context_template = Moodle idnumber for a course to be used as a template (the course will be duplicate)
| |
| | |
| The course will be created populating the fullname, shortname and idnumber configured in the plugin settings
| |
| | |
| === Service for resources duplication ===
| |
| | |
| Service URL local/ltiprovider/services.php
| |
| | |
| Custom parameters:
| |
| | |
| custom_service = duplicate_resource
| |
| | |
| custom_resource_link_copy_id = Moodle idnumber of the activity to be duplicated in the current context
| |
| | |
| === SSO to resources ===
| |
| | |
| If the context resource_link_id matches to an activity idnumber, the user will be redirect to that activity in Moodle
| |
| | |
| === Automatic creation of resources (moodle activities) ===
| |
| | |
| If this additional parameter is present in the request custom_resource_link_type (mod_forum, etc...) and also resource_link_title and resource_link_description a new moodle activity will be created
| |
| | |
| See: https://tracker.moodle.org/browse/CONTRIB-4409
| |
| | |
| === Automatic creation of contexts on SSO ===
| |
| | |
| Two additional request parameters are required:
| |
| | |
| custom_create_context (0 or 1)
| |
| | |
| custom_context_template (Moodle course idnumber)
| |
| | |
| | |
| === Resources duplication on SSO ===
| |
| | |
| Additional parameter required:
| |
| | |
| custom_resource_link_copy_id = Moodle idnumber of the activity to be duplicated in the current context
| |
| | |
| == Installing and configuring ==
| |
| | |
| Follow instructions here: http://moodle.org/plugins/pluginversions.php?plugin=local_ltiprovider
| |
| | |
| '''Important''' If you are using Moodle 2.2 or above, please, be sure that this option:
| |
| | |
| Home / > Site administration / > Security / > HTTP security Allow frame embedding
| |
| | |
| Is checked, if you leave this option unchecked your provider site will not be "embedable" via an iframe in other sites.
| |
| | |
| Once installed, a new link called "LTI Provider" will be displayed in the course navigation block .
| |
| | |
| In this page, you can add, modify and disable the tools provided in your course.
| |
| | |
| Please note that you can provide a tool n times with different configurations
| |
| | |
| There are options for hiding the page header, footer, and left and right blocks and also options for force the Moodle navigation inside a course or activity.
| |
| | |
| There are also options for assign different roles in the course or activity to the remote users.
| |
| | |
| Once added a tool, you will need to use two settings in your consumer tool:
| |
| | |
| * Shared secret
| |
| | |
| * Launch URL
| |
| | |
| Your consumer tool will ask you for a consumer private key, you can use a random string (please, do not use the shared secret as the private key)
| |
| | |
| Configure your consumer tool with these two settings. That's all
| |
| | |
| For a more detailed view of the plugin options see [http://www.somerandomthoughts.com/blog/2012/01/08/review-lti-provider-for-moodle-2-2/ this detailed review of the plugin by Gavin Henrik]
| |
| | |
| == How it works ==
| |
| | |
| === User authentication ===
| |
| | |
| * Users are created automatically in their first access to the system.
| |
| * Users are created with a hashed username and also with an auth method that disable direct login to Moodle.
| |
| * Users are allways enrolled in the course where the activities are.
| |
| | |
| You can choose which role has the Learner and the Teacher from the remote system.
| |
| | |
| There is also settings for setting Users profile default values (email visible, etc...)
| |
| | |
| If you are going to have courses with local and remote users enrolled, I recommend you to create these new roles:
| |
| | |
| * External teacher
| |
| * External student
| |
| | |
| === Grading ===
| |
| | |
| A cron job checks periodically activities for sending back grades (overall course grade or activity grade).
| |
| | |
| In order to work correctly, your php.ini settings file needs to have the following setting enabled:
| |
| | |
| allow_url_fopen = On
| |
