Course administration¶

As a course administrator, you can simply access its management page by clicking on “Course administration” in the main course page.

Students submissions¶

Statistics over students submissions are largely available in INGinious, and all the files related to them are stored and can be downloaded.

General overview¶

The administration page gives you several global list views :

All the tasks of a course, with the number of students who viewed the task at least one time, who tried and the number of tries, as well as the number of students who succeded the task. This view is the first displayed when you click on “Manage” to enter the administration.
All the students/groups of a course, with the number of tasks tried and done, as well as its global progression for students. This view can be accessed by switching to “Students”/”Groups” in the main administration page.
All the students/groups who tried a given task, if they succeded it, and the number of submissions they did. You can show these information by clicking “View results” on the main administration page or by clicking “Statistics” on the task page.
All the tasks tried by a given student/group, if (s)he/they succeded it and the number of submissions (s)he/they did. These information can be displayed by clicking “View” in the student/group list of a course.
All the submissions made by a student/group for a given tasks, with date of submission and the global result. Submissions can be displayed by clicking “View submissions” in tasks lists.

All the tables can be downloaded in CSV format to make some further treatment in your favourite spreadsheet editor.

More information about groups possibilities can be found below.

Downloading submissions¶

Student submissions can be downloaded from the Download submissions and statistics pages or the submission inspection page. You are able to only download the set of evaluation submissions (according to the task parameters) or all the submissions.

Submissions are downloadable as gzip tarball (.tgz) files. You may need some third-party software if your operating system does not support this format natively. The files contain, for each submissions, a test file with extension test containing the all the submission metadata and the associated archive folder containing all the files that have been exported (via the /archive folder inside the container) (See Run file).

Replaying submissions¶

Student submissions can be replayed from the submission inspection page. You can either replay a specific submission or replay all the submissions queried (with the replay button in the table’s header). Different replay scheme are available:

As replacement of the current student submission result. This is the default scheme for the Replay submissions page. When replayed, submission input are put back in the grading queue. When the job is completed, the newly computed result will replace the old one. This is useful if you want to change the grading scripts during or after the assignment period and want all students to be graded the same way. You can replay only the evaluation submission or all submissions. However, please note that if replayed, the best submission can be replaced by an older best submission.
As a personal copy. This mode is only available from the submission inspection page and copy the student input to generate a new personal copy. This is useful for debugging if a problem occur with a specific student submission. Submission copy is also available with SSH debug mode.

Warning

This feature is currently under testing. As the same job queue is used for standard submissions and submission replay, it is recommended not to launch huge replay jobs on a very active INGInious instance.

Task edition¶

All tasks can be edited from the webapp. To access the task editor, just click on Tasks from the main administration page. Then click on Edit task for the concerned task. You can also add new tasks from this Tasks page by clicking Add tasks for a tasks section and entering a new task id. When editing a task, you can enter basic informations and parameters in the Basic settings tab.

Based on the type of problem you want to put for the task, you can select one of the two available grading environment in the Environment tab:

Select Multiple Choice Question solver if you only want to add mcq or match types of problems. Note, the math problem type from the problems-math plugin also uses this grading environment.
Select Docker container if you want to add some more complex problems which requires to write a grading script to access the students inputs.

Adding/removing problems¶

Adding and removing problems in a task is very easy with the task editor. Go to the Subproblems tab and add a new problem-id (alphanumerical characters) and a problem type. You can configure the problem context from this page.

There are two ways to grade a problem:

Using check_answer which is only implemented for mcq and match problems

Using a specific grading script which is required for more complex problems

mcq and match problems can be entirely configured from the subproblem page with the option to set up answers. When editing a multiple choice problem, you’re asked if the student is shown a multiple-answers- or single-answer-problem and which of the possible choices is (are) good answer(s).

check_answer is only available for mcq and match problems and is automatically used when using the Multiple Choice Question Solver environment. So if you are adding more complex problems such as asking students for code implementation, you will have to write your own grading script. If you are creating this kind of problems, remember to select Docker container as grading environment in the Environment tab.

Note only a few types of problems are initially shipped with INGInious but many others are available via plugins. A list is available here

Task files¶

Task files can be created, uploaded and modified from the task edition page with the Tasks files tab. Only text-base files can be edited from the webapp. Binary files can however be uploaded.

The behaviour of the Move action is Unix-like : it can be used for renaming files.

Audiences¶

Audiences are useful to administratively separate students following the same course. They offer separate statistics to help the teacher identify problems students may encounter in this particular context.

Creation and edition¶

Audiences are created and edited from the web app in the course administration.

In the audiences list view, specify an audience description, and click on “Create new audience”. The newly created audience will appear in the list.

To edit an audience, click on the quick link “Edit audience” located on the right side of the table. You’ll be able to change the audience description, the associated teaching staff, and to specify the students. Assigning tutors will help them to retrieve their audience statistics.

The student list is entirely managed by drag-and-drop.

Course structure upload¶

You can generate the course audience structure with an external tool and then upload it on INGInious. This is done with a YAML file, which structure is described below. The course structure can be uploaded on the audience list view in the course administration.

Audiences YAML structure¶

-    description: Audience 1
     tutors:
             - tutor1
             - tutor2
     students:
             - user1
             - user2
-    description: Audience 2
     tutors:
             - tutor1
             - tutor2
     students:
             - user3
             - user4

description is a string and corresponds to your audience description
tutors is a list of strings representing the usernames of the assigned audience tutors.
students is a list of strings representing the usernames of the audience students.

Groups¶

Collaborative work is possible in INGInious. Groups define a set of users that will submit together. Their submissions will contain as authors all the students that were members of the group at submission time.

Creation and edition¶

Groups are created and edited from the web app in the course administration.

To create a new group, simply press on the “New group” button in the group list view. You’ll then be able to specify the group description, its maximum size, assigned tutors and students, as well as the required audiences to enter the group.

The student list is entirely managed by drag-and-drop. Students can be moved from one group to another by simply moving his name to the new group.

Group attribution¶

If you do not really matter the way students work together, you can set empty groups with maximum size and allowed audiences and let the students choose their groups or groups themselves. Just check the option in the course settings to allow them to gather. When submissions will be retrieved, the group members will be displayed as the authors as with staff-defined groups or groups.

Course structure upload¶

You can generate the course group structure with an external tool and then upload it on INGInious. This is done with a YAML file, which structure for groups are similar and described below. The course structure can be uploaded on the group list view in the course administration.

Group YAML structure¶

-    description: Group 1
     tutors:
             - tutor1
             - tutor2
     students:
             - user1
             - user2
     audiences:

-    description: Group 2
     tutors:
             - tutor1
             - tutor2
     students:
             - user3
             - user4

description is a string and corresponds to your group description
tutors is a list of strings representing the usernames of the assigned group tutors.
students is a list of strings representing the usernames of the group students.
audiences is a list of authorized audiences identifiers.

Backup course structure¶

Course structures (audiences and groups) can be exported for backup or manual edition via the audience/group list page in the course administration pages. Simply click on the “Download structure” button. The download file will have the same format as described above.
