CSC/ECE 517 Spring 2016 E1631 Team-based reviewing

Purpose

When a participant of a team reviewed an assignment, his/her review is independent of his teammate’s reviews. To allow teammates to discuss and review together, allowing teams to submit reviews for the team as a whole should be allowed ideally. We intend to do this in our project.

• Currently all reviews in Expertiza are done by individuals. This is true regardless of whether the assignment is done by individuals or teams .
• There are occasions when it's advantageous to review projects as a team .
• It helps foster discussion and thereby improves the process of learning.

Task Description

This project comprises of the following steps :

1. Objects of ResponseMap record the information of who reviews whom. The field reviewee_id refers to the team who is being reviewed. The field reviewer_id refers to the individual/team performing the review. We added a boolean field "reviewer_is_team" to identify if the review is performed by a team or an individual.
2. If reviewer_is_team is true, the reviewer_id will be a reference to the Teams table.
3. For an Instructor to specify whether the review is a Team/Individual based review, we will be providing a dropdown on the Review Strategy tab of assignment creation.
4. Ensure that features such as "view my scores", or the "alternate view/heat map" should continue working.
5. Concurrency control: Shouldn't allow multiple teammates to edit the team's review at the same time. The scope of the project doesn't include concurrent editing to allow multiple teammates to edit a review simultaneously.

ResponseMap in essence, records who reviews whom. Schema of ResponseMap:

id	int(11)
reviewed_object_id	int(11)
reviewer_id	int(11)
reviewee_id	int(11)
type	varchar(255)
created_at	datetime
updated_at	datetime
caliberate_to	boolean
reviewer_is_team	boolean

The description of the fields of the database for ResponseMap:

1. id: The unique record identifier.

2. reviewed_object_id: The id of the object that is reviewed. Assignments or ReviewMaps could be reviewed.

3. reviewer_id: The reviewer can either be an “AssignmentTeam” or “AssignmentParticipant”, which is indicated by the field reviwer_is_team.

4. reviewee_id: The id “AssignmentTeam” who is getting the “Response” i.e., the one whose work is being reviewed.

5. type : Indicates the type of the ResponseMap.

6. created_at: The timestamp when the Response was created.

7. updated_at: The timestamp when the Response was updated.

8. calibrate_to: A field of boolean data type.

9. reviewer_is_team: If this field is ‘true’, the reviewer_id refers to the id of the “AssignmentTeam” to which the participant belongs. Else, it refers to the id of the “Participant” itself.
