E1526. Responsive web design for Expertiza

Introduction to Expertiza

Expertiza is a large project developed as a combined effort of students and faculty using the Ruby on Rails framework. The main advantage of using Expertiza, in an educational environment, is for the instructor to introduce peer reviewing among the students. Expertiza allows the instructor to create and customize assignments, create a list of topics the students can sign up for, have students work on teams and then review each other's assignments at the end. Expertiza supports submission of almost any document type, including the URLs and wiki pages.

Expertiza is supported by National Science Foundation under Grant No. 0536558. Additional funding from the NCSU Learning in a Technology-Rich Environment (LITRE) program, the NCSU Faculty Center for Teaching and Learning, the NCSU STEM Initiative, and the Center for Advanced Computing and Communication.

Problem Statement

Despite an amazing set of functionality Expertiza offers, there are numerous parts of it that could use of a more stylish look and an improved user experience. The goal of this project is to use both Bootstrap and AngularJS to improve the look of the entire Expertiza including the representations of buttons, tables, and other elements. Certain changes in design will also improve the efficiency of the web app when it comes to the amount of time it takes for a page to be loaded.

Explanation of Tasks

Auto hides contents on the dashboard for instructors. Updating action buttons with a responsive layout. Now, when trying to open manage-courses, all records are loaded before rendering them onto the page, which takes too long time to load and is not responsive at all. Better practice is on Virgin American’s website: https://www.virginamerica.com/book/rt/a1/sfo_bos/20150401_20150402 When the website is representing the calendar, the price for each day is not actually loaded. But the skeleton of the page, which is the calendar in this case, can be displayed first.

So in Expertiza, we can create several buttons for course semesters in the page. After clicking on Fall 2014, the courses for Fall 2014 will come out. And if it is still too long and takes a long time load, we can use a ‘show more’ button ,or automatically load more data when the scroll bar reaching the end of the page, to minimize the content we need to load after one single mouse click.

Action panel too complex

We will need to reduce the number of buttons. For example, the first row are actions for assignments. The second row is for participant.So we can change it to 5 buttons with responsive design, that is, no redirection after clicking on the buttons. We will need to design better UI so that it is possible to add users to expertiza, to search a user and change roles.

Making grades_view responsive and fast

Similar to the previous task, we will need to make it responsive. Also, when clicking on the letter A-Z, no redirections should happen and only the form content should be replaced rather than the whole page. Upgrading gradesheet (grades_view) and review mapping something which webassign uses. After clicking on ‘Your scores’, all reviews are loaded before rendering the page now. That takes a long time to load and the length of review list is too long.

Task 5

View student score to be updated to show review on clicks rather than one below another. Same as task 5 Better score table using bootstrap. No need to explain

Pages To Be Modified

For this project, it is difficult to re-design all webpages and make them responsive. After discussing with the contact person, we will be focusing only on these 3 pages:

Login Page

What's wrong with it

1. Now it takes more than 15 seconds to even login to the admin's home page with the sample development database. This is definitely not good enough for a daily used web application. The cause for the long rendering time is that it will be redirected to 'tree_display/list', which needs to fetch all questionnaires, courses and assignments before page rendering.

2. The webpage looks primitive.

What changes need to be made

1. Actually it is unnecessary to fetch all data at the very beginning; if there is too much data to present, the list will be extremely long and it is quite hard for users to locate a specific course. So, we will use AngularJS and jQuery to make a asynchronous webpage that delays the database query until all the basic html elements are correctly rendered, or until the user explicitly asks for that part of data.

2. Bootstrap will be applied for better user interfaces.

Manage-Course page

What's wrong with it

As illustrated above, now the displaying list is too long and it takes too long to scroll to the end, which makes locating a specific course quite difficult.

Also, the loading time can be reduced.

What changes need to be made

1. Create several buttons for different time intervals, for example, after clicking on the button '2013-2014', only courses for 2013 to 2014 are presenting, and there is no redirection during this process.

2. The database should not be executed before the user clicks on the button. Only parts of databased is fetched when each button is clicked.

3. Bootstrap will be applied for better user interfaces.

Manage-User page

What's wrong with it

The list is too long
