Introduction

Expertiza Background

Expertiza is an open-source educational web application developed on Ruby on Rails platform. Students and Instructors (including TA's) use this application though their credentials. Instructors can add new projects, assignments etc as well edit the previous ones and at a later stage can see the student submission and grade them. They can even put a time limit (deadline) for submitting the assignment. Students can form teams for the projects, submit their work through handles (Wiki page, link to a video etc). Students can even review their teammates and other peers, as well give them any suggestions if required.

GitHub hooks to Expertiza to encourage contributors. Expertiza project is supported by National Science Foundation.

Description of the current project

This project is intended to make Bookmarks more user-friendly, credible and valid. Bookmarks in expertiza are created by reviewers and can be used by authors for their work on any project. On each line of the signup sheet are two icons, one for adding a bookmark to the topic, and another for viewing bookmarks on the topic. If the instructor allows the participants to create bookmarks, then only a participant has access to create and view them. He should be able to create a new Bookmark only if he enters a valid one.


Issues

Problem 1 :

When a user after logging into expertiza wants to add a new bookmark or view existing bookmarks for the available projects, he will click on the buttons against the specific title. Once he goes to either 'Create New Bookmark page" or "View existing bookmarks page", he's not able to go back to Sign-up sheet using "back" button.


Enhancements to this problem :


We can go back to Sign-up sheet after clicking on "back" button.


Problem 2 :


If a user clicks "Add Bookmarks" button, he will be navigated to a "Add a new bookmark page" where he can give details of new bookmark (like URL, description etc ). A messgae " You've successfully created a new bookmark" is displayed on the console even if we give null values (i.e if we do not fill up those fields at all).





Enhancements to this problem:





Problem 3:


When the instructor doesn't give access for participants to add/view bookmarks, the participants are still able to access them. He un-checks "Allow participants to add bookmarks" button and participants are still able to access them.


Files modified in current project

1. app/views/bookmarks/list.html.erb  : This file is a view for listing the existing bookmarks of a particular Title of the project.

3. app/views/sign_up_sheet/_actions.html.erb : This file is a view for showing the actions against the title of the bookmark.

Future Work

3. A function to add extra credits automatically if a participant had submitted more than threshold number of useful bookmarks.
