This wiki page is the description of the E17A1 semester project - Let experts as well as students do reviews - for Fall 2017, CSC/ECE 517.

Introduction

Expertiza is an open source project based on Ruby on Rails framework. The Expertiza project is software to create reusable learning objects through peer review. It is a web application where students can submit and peer-review learning objects (articles, code, web sites, etc). It is used in select courses at NC State and by professors at several other colleges and universities. It also supports team projects, and the submission of almost any document type, including URLs and wiki pages. Expertiza enables the instructor to create new and customize existing assignments. It also enables the instructor to create a list of topics the students can sign up for as part of a project. Students can form teams in Expertiza to work on various projects and assignments. Expertiza supports submission across various document types, including the URLs and wiki pages.

Existing Limitations

  • Currently, the functionality of calibration is limited. It does not support varying-rubric-by-round feature.
  • For student side, there is no way to notify for an author to tell that a particular review that they received was submitted by an expert.
  • Students are not able to see how an expert has rated the assignment, they can only see calibration results for calibrated assignments by clicking on the “Show calibration results” link.

Tasks

  • Change in DB Schema
    • “is_calibrated” field in assignment table to “has_expert_review”
    • “calibrate_to” field in response_map table to “expert_review_to”
  • User interface changes
    • Original interface

Updated Updated

    • Instructor side
      • In assignment setting page (“General” tab), change the checkbox title from “Calibrated peer-review for training?” to “Add expert peer review?”

      • When instructor clicks that checkbox, there will be a new tab named “Calibration”. Change the tab name from “Calibration” to “Expert review” on the assignment setting page
    • Student side
      • Change the link title from “show calibration results” to “show expert peer-review results”Updated
      • Change the title in “response/show_calibration_results_for_student.html.erb” to start with “Expert review comparison report for”Updated
  • New features
    • Let expert review support the vary-rubric-by-round functionality
    • Support multiple expert reviews (Both TAs and instructors could do expert reviews)
  • Tests
    • Create expert_review_spec.rb file in spec/features folder
  • Additional minor changes
    • Reflect changes in DB schema at all places, including tests.
    • Change the partial file name from “_calibration.html.erb” to “_expert_review.html.erb”
    • Rename “response/show_calibration_results_for_student.html.erb” to “response/show_expert_review_results_for_student.html.erb” and also change other call sites

Proposed Solution

Change in database The following schema changes will be implemented using a new migration file:

  • “is_calibrated” field in assignment table to “has_expert_review”
  • “calibrate_to” field in response_map table to “expert_review_to”

Change in User interface The following files will be edited to reflect the changes in user interface as mentioned in tasks:

  • #assignments/edit/_calibration.html.erb
  • #response/show_calibration_results_for_student.html.erb
  • #student_review/_responses.html.erb
  • #student_review/list.html.erb
  • #assignments/edit.html.erb

Test Plan

  • Existing tests should be changed according to changes in database schema and user interface.
  • A new test file expert_review_spec.rb will be created to unit test the changes with the following steps:
  • Log in using instructor's or teaching assistant's credentials.
  • General tab should have the checkbox titled 'Add expert peer review?'
  • Click on the checkbox.
  • There should be a tab "Expert review" on the assignment setting page.
  • Log out and log in back using student's credentials.
  • There should be a link titled 'show expert peer-review results'
  • Test multiple expert reviews by submitting multiple reviews when logged in as an instructor or TA for the same assignment.
  • Also test the vary-rubric-by-round functionality.

New Test

New tests will be written to test the new features added, like :

  • assignment should support multiple expert review.
  • current assignment should support vary-rubric-by-round.
