Expertiza - Information Display and Student Interaction

Expertiza is a web application developed using Ruby on Rails that serves as a peer-review system. The application allows students to submit and peer-review learning objects (articles, code, web sites, etc)<ref>Expertiza on GitHub</ref><ref>Expertiza Wiki Page</ref>. It is an open source project and it's codebase is maintained in GitHub. Our contribution in this project is by improving the display of assignments for all the instructors and also to improve the dashboard for student to view and compare their performance of the assignments.

Introduction

Background

Scope

Purpose

Approach

As the project was originally assigned to students two years ago, the functionality is mostly complete. The main concern is that, as the project was completed 2 years ago (in December 2012), it was made for an older version of rails.

General Approach

Our general approach to the project would be as follows:

  • Run the current project with rails 4
  • Check the functionality to find out the incompatible parts
  • Refactor the parts of code that do not function as expected and port them to rails 4 specification
  • After making sure everything runs, refactor the entire code to make sure it follows the global code rules.

Specific Approach

The specific approach to each of the two functionality is as follows:

Better display for assignments
