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. We are contributing to Expertiza as a part of our Object-Oriented Design and Development's Open-Source Software (OSS) Project. Our goal in this project is to refactor the StudentQuiz controller. In this Wiki Page, we would be explaining the changes that we have made for the same.

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:

Files involved

Dashboard for students

• Model
ScoreCache.rb
• View
grades\view_my_scored.html.erb
• Controller
grades_controller.rb, review_mapping_controller.rb,response_controller.rb
• Database tables
Assignments,Participants, score_caches, response_maps,responses

Functionality of each file
