Project Description

The full E17A2 project topic description can be found here.

The goal of this project is to create a simple badging system for Expertiza, allowing students to earn badges when they meet certain predefined criteria while using the platform.

This project is concerned with two preliminary badges — "Good Reviewer" and "Good Teammate" — but the design will be such that the badging system can be easily extended to include more badges in the future.

Per the full project topic description, the badges will be designed using Credly.

Previous work on this project topic revealed that any text included on the badges is too small to read, so all text should be removed from the badges and instead appear when the badges are hovered over.

The "Good Reviewer" badge will be awarded to students who receive very high review grades.

The "Good Teammate" badge will be awarded to team members who receive very high teammate review scores.

By default, the "threshold" for earning these badges will be set to a score of 95, but this value will be configurable on a per-assignment basis by the instructor.

A new "Badges" tab will be added for instructors on the "Edit Assignment" page where instructors can add badges and configure the badge criteria for a given assignment.

Badges a student has earned can be seen when they view their "Task List" page, and an instructor will be able to view all badges earned by students when they view the "Participants List" page.

Please refer to the "Preliminary Mocks" section below for further detail.

Project Requirements

1. Create badges using Credly (do not include text)

        1.1. Create the "Good Reviewer" Badge

        1.2. Create the "Good Teammate" Badge

        1.3. Store these badge images in the app/assets/images/badges directory

2. Create tables for the badging system

        2.1. Create a table named badges with the following attributes

                2.1.1. id — primary key

                2.1.2. name — varchar

                2.1.3. description — varchar

        2.2. Create a mapping table named assignment_badges with the following attributes

                2.2.1 id — primary key

                2.2.2 badge_id — foreign key

                2.2.3 assignment_id — foreign key

                2.2.4 threshold — int

        2.3. Create a mapping table named awarded_badges with the following attributes

                2.3.1. id — primary key

                2.3.2. badge_id — foreign key

                2.3.3. participant_id — foreign key

3. Change the UI so that instructors can add and configure badges, and students can view their badges

        3.1. Add a new "Badges" tab to the assignments/edit page

        3.2. Add badge icons to the student_task/list page for students to view

        3.3. Add badge icons to the participants/list page for instructors to view

4. Write feature tests to verify the modifications

        4.1. Include tests in the a new badge_system_spec.rb file in the spec/features directory

Tables

The following is an example of mock data in the badges table:

id (primary key)	name (varchar)	description (varchar)
1	Good Reviewer	This badge is awarded to students who receive very high review grades.
2	Good Teammate	This badge is awarded to team members who receive very high teammate review scores.

The following is an example of mock data in the assignment_badges mapping table:

id (primary key)	badge_id (foreign key)	assignment_id (foreign key)	threshold (int)
1	1	1	95
2	2	1	95
3	1	2	90
4	2	2	85
5	1	3	80

The first row represents that the badge with badge_id 1 ("Good Reviewer") has been activated for assignment 1 with the default threshold of 95.

The second row represents that the badge with badge_id 2 ("Good Teammate") has been activated for assignment 1 with the default threshold of 95.

The third row represents that the badge with badge_id 1 ("Good Reviewer") has been activated for assignment 2 with a customized threshold of 90.

The fourth row represents that the badge with badge_id 2 ("Good Teammate") has been activated for assignment 2 with a customized threshold of 85.

The fifth row represents that the badge with badge_id 1 ("Good Reviewer") has been activated for assignment 3 with a customized threshold of 80.

The following is an example of mock data in the awarded_badges mapping table:

id (primary key)	badge_id (foreign key)	participant_id (foreign key)
1	1	1
2	2	1
3	1	2
4	2	3
