=== Improve SCORM plugin ===
There are a number of areas of SCORM that could be improved as part of a GSOC project, some of these are bigger projects and others could be combined to form a single project.


As you become more involved in Moodle development, you might like to learn more about the [[Coding|coding conventions]] used and how changes to Moodle core code are [[Process|processed]].
These are just some examples, take a look at the open SCORM issues in the Moodle tracker for a list of other issues.
* Improve Grading (MDL-51086, MDL-52871, MDL-37421)
* Improve validation of SCORM packages (MDL-38060, MDL-24057)
* Convert YUI Treeview to use Jquery (Moodle is moving away from YUI and the existing Treeview has a few issues)
* Choose where to send users after completing SCORM (MDL-61677)


==Potential projects==
Requirement for prospective students:
* We require prospective students to make an attempt at fixing at least 1 issue in the Moodle tracker before their proposal can be considered. This MUST be completed before your application can be considered valid.

This evolving page lists possible Moodle projects for new developers derived from community suggestions.
=== Acceptance tests for the Moodle app ===


''If you have any ideas for new features in Moodle which might be suitable as projects for new developers, please see [[New feature ideas]].''
Since Moodle 3.7 it will be possible to write and run acceptance tests for the Moodle app.


=== Pusher integration for HTML5 push notifications ===
Tasks:
Moodle supports message output plugins. By adding a plugin for pusher.com and a Javascript service worker to listen for push notifications, we can have realtime HTML5 notifications on all platforms.
* Write new acceptance tests for the Moodle app

=== Ability to crop/resize/rotate an image in atto ===
Requirement for prospective students:


Moodle comes with it's own HTML editor known as 'atto' (see https://docs.moodle.org/dev/Atto). The editor functions similarly to other editors out there, like TinyMCE, but is tailored to Moodle. It comes with multiple plugins that allow users to perform tasks, such as changing the font size, the alignment, adding links etc. One of these plugins allows the user to add an image to the text editor with the ability to specify the size and alignment of the image via text input. The idea of this project is to extend and improve this current plugin so the user can crop/resize/rotate the image via JS - making the whole experience easier and more aesthetically pleasing.
* We require prospective students to set-up and run in a local environment the existing tests following this documentation: [[Acceptance testing for the mobile app]], students must record a video of the tests running on a local machine.
* We also require students to create an additional simple test (detailed instructions for writing tests are available in the previous link)

:'''Difficulty level''': Medium
:'''Possible mentor''': [https://moodle.org/user/view.php?id=1057750 Mark Nelson]


=== Improve Behat tests in SCORM plugin ===
This is a follow-up project for a [[GSOC/2016#Plugin skeleton generator|successful GSOC 2016 project]] that resulted in a new tool allowing developers to quickly generate a skeleton (scaffolding, template) for a new Moodle plugin. The tool proved to be a helpful helper with significant impact on the quality of Moodle plugins code. This follow-up project aims at further improvements of the skeleton generator. The primary goal is to implement a developer-friendly user interface / front-end editor allowing to configure the plugin's properties (recipe file) easily. The UI should guide the developer through the process of designing and defining the plugin properties and facilitate the whole process.
The Moodle SCORM plugin does not contain very many behat tests and most tests are manual. The Claude Ostyn diagnostic SCO should be used to implement a range of new Behat tests to cover the functionality that the SCORM module provides.


Deliverables:
* We require prospective students to make an attempt at fixing at least 1 issue in the Moodle tracker before their proposal can be considered. This MUST be completed before your application can be considered valid.
* Behat tests for all existing SCORM QA tests (where possible)
* Behat tests for all SCORM settings (eg standards mode, mastery score settings etc)
* The code should pass 100% of the Moodle codechecking tools to ensure the code meets with Moodle Guidelines.


Extra requirement for prospective students:
:'''Skills required''': PHP + JS
* We require prospective students to make an attempt at fixing at least 1 issue in the Moodle tracker before their proposal can be considered - on top of this you must also attempt to convert one existing QA test into a Behat test.

=== Advanced Grading in Forums ===
=== Add multi-class capabilities to Moodle's machine learning backends ===
Finish the work required to add the advanced grading feature to the Moodle forum activity. This builds on some existing work available at MDL-31860


Deliverables:
Moodle includes an analytics API that uses machine learning for binary classification. This is enough for classification problems like "student at risk" vs "student not at risk". We want to expand this API capabilities by supporting multi-class classification, so we could write models like "very low grade", "low grade", "pass", "best student ever".
* Modify the forum grading so that it pushes 2 grade areas (or 3 including ratings) into the gradebook instead of a single grade.
* Improve interface that allows overall forum participation grading.
* Behat tests for all new functionality.
* The code should pass 100% of the Moodle codechecking tools to ensure the code meets with Moodle Guidelines.


Extra requirement for prospective students:
Tasks:
* We require prospective students to make an attempt at fixing at least 1 issue in the Moodle tracker before their proposal can be considered - on top of this you must also attempt to convert one existing QA test into a Behat test. This MUST be completed before your application can be considered valid.
* Modify the two machine learning backends included in Moodle core to support multi-class classification problems. This includes the PHP ML backend (based on php-ml library) and the Python ML backend (Tensorflow).

[https://angular.github.io/protractor/#/ Protractor] is an end-to-end test framework for AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.
=== Add regressors to core machine learning backends ===


The basements for this project are done, see MOBILE-1179, the only remaining work is to add more tests to the app and document the set-up process in the Moodle developers wiki.
Moodle includes an analytics API that uses machine learning for binary classification. This is enough for classification problems like "student at risk" vs "student not at risk". We want to expand this API capabilities to support regression, so we can write models that estimate linear values instead of classes.

=== Add search to more moodle components ===
Requirement for prospective students:

MDL-31989 is introducing global search to Moodle to index moodle data in an external source and to retrieve data back from that external source. There are some module components, like glossary or databases that can use the search engine to index their data on it, so moodle users with permissions can access them quickly. This project would be about implementing the search API in some moodle components, the number of components can vary depending on the time available, but ideally this should land into core.

=== Elastic search ===
A new process should be implemented that frequently changes the displayed QR code and expires the old QR code, making it difficult for the QR code to be shared outside the session. As part of your project application, please suggest your ideas on how to minimise the impact of server performance while dealing with rotating QR codes.


MDL-31989 is introducing global search to Moodle to index moodle data in an external source and to retrieve data back from that external source. The only search engine that will be initially supported will be solr, as elasticsearch has a good use base would be nice to write a search_elastic plugin implementing moodle's search engine API. This does not necessarily need to go into core.
