CSC/ECE 517 Fall 2016/E1680. Improve survey functionality

Background

Goal

Expertiza should be able to distribute surveys to the users. The survey can be one of the following: 1. Course survey (all the participants of the course can take it). 2. Global survey (all the users in Expertiza can take it).
The survey can also be targeted (the admin can specify a group of people who will receive this survey).
The three kinds of surveys in this project are:

• 1. survey_questionnaire.rb
• 2. global_survey_questionnaire.rb
• 3. course_evaluation_questionnaire.rb.

Survey questionnaire should be a subclass of questionnaire. The creation, editing, filling in, and checking that all the questions have been answered survey should be similar to the procedure used for other types of questionnaires (e.g. peer-review questionnaires). There should be a page to see the distribution of results for any question (e.g., how many people answered “1”, how many answered “2”, etc.). This page should not only be designed for surveys, but also for other types of questionnaires. (E.g. this view be able to show the score distribution for a question in other types of questionnaires, no matter whether it is a survey question like “how much do you like the course?” or a peer-review question like “how well did the author test the code?”)
We should use the same controller method to take the survey as to fill in the peer-review, namely, response_controller. We should use the same code to display the existing survey responses as to display the responses in peer reviews.
For each course or assignment, the admin/instructor should be able to create a survey and have some (or all) of the participants receive the survey. When a user is assigned to take part in a survey, a survey_participant record should be created for that user in the participants table.

Issues

Adding Participants to the survey:

• Instructor or admin both can add survey for any course or assignment

• The creator would be able to select the participants based on the scope of the survey, that

is, all the students or all the expertiza users or specific group of people

Adding all the global questionnaire questions:

• There would be a generic set of questions which will be included in

global_survey_questionnaire

• These questions will be by default added to every survey the user create

• But, creator will be able to omit them with one ‘checkbox’ button

(Or, we can have specific selections for each of the questions to be included)

• Or, there can be option of separating the global survey and course survey. The quiz taker will

take the global survey first and then the course survey

Adding the data to database:

• For each participant added by the creator of the survey, a database entry would be made in

participant table along with appropriate details

Design

Requirement

There should be a page to see the distribution of results for any question (e.g., how many people answered “1”, how many answered “2”, etc.). 
This page should not only be designed for surveys, but also for other types of questionnaires.
(E.g. this view be able to show the score distribution for a question in other types of questionnaires, no 
matter whether it is a survey question like “how much do you like the course?” or a peer-review question like 
“how well did the author test the code?”)

Proposed Implementation

The required page for this implementation would look like this:

Our page to see the distribution of results for any question would render a similar Bar graph 
showing the no of people who  answered a choice amongst the options.
The vertical axis would show the no of people.
The horizontal axis will show the possible answers to the question.
To implement this in Expertise we can use JQPlot  Rails or some other graph plotting plugin.

The JQuery code might look like

We will have to integrate the Jquery plugin and create a .erb file in views which will have similar 
Jquery code to render a bar graph based on the data provided.
