This wiki page describes the changes made under E2075, to ensure calibration submissions are copied along with calibration assignments for CSC/ECE 517, Fall 2020.

About Expertiza

Expertiza is an open source project based on Ruby on Rails framework, created and maintained by the joint efforts of students and faculty at North Carolina State University.

It allows the instructors to create new assignments and customize new or existing assignments. Expertiza also allows an instructor to create a list of topics the students can sign up for. Students can form teams on the web application to work on various projects and assignments together. Additionally, students can peer review each other's submissions allowing them to improve upon their work. Expertiza supports submission across various document types, including the URLs and wiki pages.

Introduction

The Expertiza project allows "calibration assignments" to be performed where students are asked to review work that has also been reviewed by a member of the course staff. Calibration is the term used for rectifying, or checking or determining something. In the context of this project, a 'Calibrated review' is one which is performed by a student, so that (s)he can verify their work by comparing it with the instructor's response for the same assignment. If the student’s review “resembles” the staff-member’s review, then the student is presumed to be a competent reviewer. Since calibration reviews are meant as reference for better performance of peer reviews (which are performed later), they are not graded.

Problem Statement

Project Purpose

Calibration submissions should be copied along with calibration assignments.

Issue in current implementation

On creating a copy of a previous assignment, say for example Design Exercise, Fall '20 for the Fall '21 semester - the calibration assignments associated with it are not copied over. The instructor is required to impersonate extra participants, and submit work on behalf of each of the extra participants. This is obviously extra trouble, and it would be a lot more convenient if an instructor didn’t have to resubmit the same calibration submissions over and over, every semester.

The following steps were taken to test the aforementioned issues:

Step 1: On copying the Design exercise assignment

Step 2: The original file contains the following calibration reviews

Step 3: However, the copy doesn't contain any of the calibrated reviews

Implementation

MVC

The project is implemented in Ruby on Rails that uses MVC architecture. We have three separate modules namely User Interface, Database Model and Control Flow (Model, View and Controller).

Principle

We tend to reuse the already existing functionalities and data to our design. The calibration reviews that are present in the previous exercise will be copied into the newly created exercise which would prevent the instructor from performing additional tasks of performing reviews repeatedly. This would also prevent code duplication and additional memory usage.

Design

The following must be added to the current implementation:

Participants with 'View' and 'Edit' actions in the calibration tab are copied over to the new version, as they are considered calibration submissions
All hyperlinks and files associated with the above mentioned participants are copied over as well
Participants with the 'Begin' action are not copied over
A check is put in place to make sure that these steps are taken only for copying assignments with calibration reviews. This is signified by a calibration tab in the tool bar, on the edit page.

Test Plan

Manual Testing Plan

To check if the UI is working as expected [No broken links]
The submissions [Files and Hyperlinks] are copied when an assignment for calibration is copied.

Directions for Manual Testing

The following steps must be performed to test the project UI:

Step 1: Log in as an Instructor, with Username - instructor6, Password - password

Step 2: Find an assignment with calibration submissions present, which is represented by a calibration tab on the editing page.
In this case, the assignment chosen is called "Design exercise"

Step 3: Copy the assignment, by selecting the icon shown below

Step 4: On inspection of the copied assignment, it is observed that the calibration assignments have been copied over.

Step 5: In the similar way, if the calibration tab has any files attached by the reviewers, then the files would get copied along with the participant details. Below is an assignment in which one participant has submitted a file named review1.txt in calibration.

Step 6: As the assignment has a file in calibration tab, even the copy of the assignment will have the same file with same content copied over to the calibration tab. Below is the copied assignment's calibration tab containing review1.txt created by the participant in original design exercise

+Below are the rspec testcases used to test the application.
-* Validation of the models
-* Sanity and basic functionality of controllers

-** This involves essentially checking if the copied calibration's corresponding model has entries for the submissions
