Sections: specifications & ideas

with 5 comments

One of the functionality we would like to implement this semester is section management.

Here is the content of this post

Details specifications

  • Group management : the groups should be formed of two or three students of the same section ;
    • instructors need to be able to add the students section through the web interface or via the CSV file upload.
    • the student list should have filter to sort students per section.
    • instructors should be able to switch from two modes, in the assignment property tab:
      • groups have to be formed with students from the same section.
      • groups DO NOT have to be formed with students from the same section.
    • when switching to this mode, the application should display a warning message if some of the students don’t have a section associated to them.
    • students should see whether the groups have to be formed of students in the same section or not.
    • when the mode is activated, inviters should not be able to invited students in another section than theirs.
    • if some students don’t have a section, inviters with no section will be able to invited only students without any sections.
  • Deadlines : Each section needs to be associated with one specific deadline ;
    • this functionality can be enabled only if groups are limited to same-section students.
    • when enable, instructors can specify one deadline per section in the assignment property view.

If deadlines are specified per sections, it is logical that submissions rules could be too. For the first implementation, we will disable submission rules.

Database schema

section_db_schema

Sections table

This table is used to save all the sections. In the case of UofT, it should be from 2 to 3 sections. For Centrale Nantes (a French engineer school), 12 sections (groups).

id: int
name: string

Users table

We added a foreign key to sections. This is mostly used for students, but can also be used for Graders (we could then map graders to groups per sections).

Assignments table

There are a lot of options that can be added with the new section scheme.

section_due_dates: boolean, false
section_groups: boolean, false
section_submission_rules: boolean, false

Section_due_dates table

This links assignments and section, to add a specific due date to each section for an assignment.

id: int
section_id: int, fk
assignment_id: int, fk
due_date: date

If you have any thought, please chime in !
