CSC/ECE 517 Fall 2017/E17A4 Allow calibration to be part of an assignment

This wiki page describes the changes made according to the specification of E17A4 final project assignment for Fall 2017.

Problem Statement

In order to gain practice, the Student should be able to give calibration reviews before providing peer reviews. Thus, the Instructor should be able to enable calibration for every new and existing assignment. By this way, the student can improve peer reviewing by comparing his/her results with expert reviews for the same assignment.

Limitation

At present, the instructor is able to calibrate the students’ peer review abilities on Expertiza by creating only a separate assignment for this purpose. In this separate assignment that the instructor creates, the student and the instructor will simultaneously do peer review for the project. After submission of the reviews, the student's and instructor's reviews are compared and a calibration report is generated for the student to view and improve their peer reviewing skills.

Unfortunately, for students to practice peer reviewing, a separate assignment has to be created every time. In order to facilitate sufficient practice for peer review, this is not a convenient method.

Proposed System

The objective of this project is to enable calibration to be one part of the normal assignment. The instructor should be able to turn on this feature if necessary and provide the corresponding calibration deadline. The student should be pre-assigned sample assignments. Once the student submits the calibration reviews, the calibration results comparing the student and expert review are provided to the student. This feature should be available for normal assignments.

System Overview

Calibration review is the sample practice peer review used for comparing students' review with expert's review. The calibration results show the results and the experts' reviews, based on which the students can improve their peer reviewing skills.

In the current system has the following actors:

a)Instructors:Users who have administrative privileges to create/edit assignments and impersonate students

b)Students: Users who submit assignments and peer reviews

The current system allows the instructors to create assignments separately for calibration purposes. This is clearly inconvenient and ineffective as the students will not receive enough practice for peer reviewing on their normal assignments beforehand.

Hence, if students were able to compare their reviews with the experts' review for normal assignments before providing actual peer reviews, they will be able to learn and improve their peer reviewing skills from the experts. Therefore, we have to integrate this feature of calibration reviewing in normal assignments as well.

In the current system, the calibration functionality works correctly. In the assignments' edit page, once the instructor enables “Calibration for training?” and saves the assignment, an extra tab "Calibration" appears. After this, the instructor needs to add several sample assignments (right now instructor needs to impersonate several students to submit sample assignments) and do expert review beforehand. This is the existing functionality.

In the proposed system, the flow of the assignment submission done by the student, changes. First is the calibration review of sample assignment, then normal assignment submission followed by rounds of peer reviews. In the proposed system, once the “Calibration for training?” is enabled, in addition to the “Calibration” tab, a row for calibration deadline entry appears under the “Due dates” tab before any submissions row. The instructor has to enter the deadline for the calibration review and save the assignment.

Consequently, the student assignments page, the stage of this assignment will be set to “Calibration” during the calibration period. Furthermore, once the student submits one of the calibration reviews in the student_review page, the student can view the calibration results in the “Show calibration results” link. The calibration result shows the comparison of the student’s reviews and the respective instructor reviews. Based on the result, the student will learn to give better peer reviews for the particular assignment.

After completion of the calibration reviews (before the due date), the student should submit the assignment on/before the submission deadline, which is the existing functionality. Since the students have had enough experience during the calibration period on peer reviewing, the next task will be carried over effectively.

Peer reviewing is the concept of review your peer’s work. This concept enables the students to understand the solution to a problem from multiple perspectives. This will also embed new ideas and the skill of constructive criticism in the student. And, hence, the student will provide peer reviews after the submission of their work. These rounds of reviews will be controlled by the instructor. Once all the submissions are made, the assignment’s stage gets assigned the finish status.
