CSC/ECE 517 Fall 2019 - E1981. Student-generated questions added to rubric

2019-12-11T23:28:27Z

Cwang64:

== Introduction ==
The rubrics in expertiza are created by instructors. These Rubrics only contain questions that are related to the existed topics. Now, Expertiza only supports students to pull questionnaires is specific rubrics to get some help. Even that they can ask about anything that is relevant to all the projects that will be submitted But when students encounter difficult problems which are not in the existed topics, and they want to get special advice on that new field, the demand for creating supplementary review questionnaire raises. This project (E1981) aims to solve this problem by allowing students to add questions to the standard instructor generated rubric so that they can get specific feedback on from the reviewers.

The github repository is https://github.com/Jas0nch/expertiza. And the demo video in youtube is ...

== Proposed solution ==
We will add the Supplementary Review Questions to the current Review Questions, and show these student-generated questions under the rubric given by instructor. Even though these questions won't be graded, they will eventually provide diversity for feedback. It will increase the benefit that each team gets because they can get feedback that is specific to their project.

== Implementation ==

=== Design Strategy ===

Goal: In Expertiza, all kinds of rubrics and surveys are subclasses of Questionnaire. A Questionnaire can contain “questions” of several types (e.g., checkboxes, dropdowns, text boxes). We'll add a new subclass of Questionnaire called, say, SupplementalReviewQuestionnaire.

1. there should be a checkbox when creating the whole questionnaire to indicate whether this questionnaire will have supplemental review questions or not.

2. there should be a button that has the content "add supplemental questions".

a. if you click that button, it will redirect to a page that an instructor uses to create a supplemental questionnaire.

b. when the supplemental questionnaire is created, it should append to the existed questionnaire.

3. After the reviewer finished the review, student can find the supplemental questionnaire in the review page.

How we will do this:

1. add a variable in the questionnaire class.

2. add another file for a supplemental questionnaire and save them to the database.

3. add a method to get the corresponding supplemental questionnaire and to add questions into the existed questionnaire.

4. we should add another method to show the supplemental questionnaire in the review page.

=== Modifications in the User Interface (Todo) ===

1. Assignment Creation Page in Instructor's Account

We plan to implement a check box under the column of Rubrics in the assignment creation page indicating whether the instructor allows students to add specific questionnaires with respect to their projects.

2. Your Work Page in A Student's Account

We plan to implement a link or button on the Your Work page of an assignment of a student whose assignment is enabled to create supplementary review questionnaires by the instructor, in order to redirect to the Review Rubrics Creation page.

3. Review Rubrics Creation Page

In this page, students are able to create supplementary review questions regarding the specifics of their own assignments.

4. Review Page

In the Review Page of reviewers, the supplementary review questions created by the owner of the assignment will be shown to reviewers along with the standard review questions created by the instructor.

5. Review Results Page

The Review Results Page should display the results of standard questions created by the instructor as well as the results of supplementary review questions created by the instructor.

== Use Cases ==

[[File:Use_Cases.jpg‎]]

== Test Plan ==

=== RSpec Test ===

* There should be no link for "Supplementary Review Questionnaire" for team members or reviewerss, if the instructor disables this section in Assignment Creation Page.

* If the instructor enables this section, the link for "Supplementary Review Questionnaire" should appear in the "Your Work" section of a student, and redirect to Review Rubrics Creation Page.

* After created or edited, the supplementary review questions should appear as part of the whole review question sheet in Review Page (along with the standard review questions created by the instructor), to team members, reviewers, and the instructor.

* After a reviewer saves or submits, the responses to the supplementary review questions should appear when (s)he views the responses.

* After review deadline, all responses to the supplementary review questions of reviewers should appear in My score page of students.

CSC/ECE 517 Fall 2019 - E1951. Remove multiple topics at a time

2019-10-27T22:05:37Z

Cwang64:

This wiki page is for the description of E1951. Remove multiple topics at a time (Issue #1409).

=='''Introduction'''==
The Expertiza project is software to create reusable learning objects through peer review. It also supports team projects, and the submission of almost any document type, including URLs and wiki pages.

=='''Problem Statement'''==
If an instructor or a TA wants to delete topics he has to delete one topic at a time and has to wait for the page to refresh and then (s)he can proceed to delete the next topic, topics can only be deleted one by one.

===To fix the problem:===
1.There should be a checkbox column, along with other columns in “Topics” tab, where a user can select the topics (s)he wants to delete.

2.There should be a delete button/link at the end of the topic table with the name “delete selected topics” to delete the selected topics after a confirmation, prompted post clicking the button/link.

3.There should be a button/link alongside “delete selected topics” by the name “Select all” so that a user can select all and delete them in one go after clicking on “delete selected topics”.

=='''Solution'''==

===1.Modify view===
File: app/views/sign_up_sheet/_add_topics.html.erb

Add bottoms of 'Delete select topics' and 'Select all'
<pre>
<input type="button" value="Delete select topics" onclick="deleteTopics()" />|

<a id="select all " onclick="checkAll()">Select all</a> |
</pre>

File: app/views/sign_up_sheet/_table_header.html.erb

Add 'Select' header
<pre>
<th width="5%">Select?</th>
</pre>

File: app/views/sign_up_sheet/_table_line.html.erb

Add selected checkbox
<pre>
<td><input type="checkbox" name="query_mySelectBox"></td>
</pre>

===2.'Select All' function===
File: app/assets/javascripts/signup.js

Select All function checks all checkbox of topics.
<pre>
function selectAll(source) {
checkboxes = document.getElementsByName('mySelectBox');
for (var i = 0, n = checkboxes.length; i < n; i++) {
checkboxes[i].checked = source.checked;
}
}
</pre>

===3.'Delete' function===
File: app/controllers/sign_up_sheet_controller.rb

Define delete all and get selected topics methods.
<pre>
# This deletes all selected topics
def delete_all_selected_topics
load_all_selected_topics
@stopics.each(&:destroy)
flash[:success] = "All selected topics have been deleted successfully."
respond_to do |format|
format.html { redirect_to edit_assignment_path(params[:a_id]) + "#tabs-2" }
format.js {}
end
end

# This get all selected topics
def load_all_selected_topics
@stopics = SignUpTopic.where(assignment_id: params[:a_id], topic_identifier: params[:idents])
end
</pre>

File: app/views/sign_up_sheet/_add_signup_topics.html.erb

<pre>
#change <table class="table table-striped"> to
<table class="table table-striped" id="Table1">
</pre>

File: app/views/sign_up_sheet/_add_topics.html.erb

Delete function destroys all selected topics.
<pre>
<script>
function deleteTopics() {
var msg = 'Are you sure? It will destroy all selected topics';
if (confirm(msg)) {
var identifiers = []
$("#Table1 input[type=checkbox]:checked").each(function() {
var ient = $(this).closest('tr').find('#ident').text();
identifiers.push(ient);
});
jQuery.ajax({
url: '/sign_up_sheet/delete_all_selected_topics',
method: 'POST',
data: {
idents: identifiers,
a_id: <%= @assignment.id %>
},
success: function() {
location.reload();
}
});
} else {
window.location.href = '<%= edit_assignment_path(@assignment.id) + "#tabs-2" %>';
}
}
</script>
</pre>

File: app/views/sign_up_sheet/_table_line.html.erb

<pre>
#change <td><%= topic.topic_identifier %></td> to
<td id='ident'><%= topic.topic_identifier %></td>
</pre>

File: config/routes.rb

Add url.
<pre>
post :delete_all_selected_topics
</pre>

=='''Result'''==
Before clicking 'Select all' bottom, there are checkboxes that could select each topic.
[[File:Before_select.png]]
After clicking 'Select all' bottom, all checkboxes are selected.

[[File:After_select.png]]
After pushing 'Deleted selected topics', there's a confirmation alert. After clicking yes could delete all topics.

[[File:Confirm_deletion.png]]
=='''Test'''==
File: spec/controllers/sign_up_sheet_controller_spec.rb

Select assignment with id '834' and topic with id ['E1732'] as params. Post params to delete_all_selected_topics. Expect success flash with 'All selected topics have been deleted successfully.' and redirect to '/assignments/834/edit#tabs-2'.
<pre>
describe '#delete_all_selected_topics' do
it 'delete_all_selected_topics and redirects to edit assignment page' do
allow(SignUpTopic).to receive(:find).with(assignment_id: '834',topic_identifier: ['E1732']).and_return(topic)
params = {assignment_id: 834, idents: ['E1732']}
post :delete_all_selected_topics, params
expect(flash[:success]).to eq('All selected topics have been deleted successfully.')
expect(response).to redirect_to('/assignments/834/edit#tabs-2')
end
end

CSC/ECE 517 Fall 2019 - E1951. Remove multiple topics at a time

2019-10-27T21:20:29Z

Cwang64:

This wiki page is for the description of E1951. Remove multiple topics at a time (Issue #1409).

=='''Introduction'''==
The Expertiza project is software to create reusable learning objects through peer review. It also supports team projects, and the submission of almost any document type, including URLs and wiki pages.

=='''Problem Statement'''==
If an instructor or a TA wants to delete topics he has to delete one topic at a time and has to wait for the page to refresh and then (s)he can proceed to delete the next topic, topics can only be deleted one by one.

===To fix the problem:===
1.There should be a checkbox column, along with other columns in “Topics” tab, where a user can select the topics (s)he wants to delete.

2.There should be a delete button/link at the end of the topic table with the name “delete selected topics” to delete the selected topics after a confirmation, prompted post clicking the button/link.

3.There should be a button/link alongside “delete selected topics” by the name “Select all” so that a user can select all and delete them in one go after clicking on “delete selected topics”.

=='''Solution'''==

===1.Modify view===
File: app/views/sign_up_sheet/_add_topics.html.erb

Add bottoms of 'Delete select topics' and 'Select all'
<pre>
<input type="button" value="Delete select topics" onclick="deleteTopics()" />|

<a id="select all " onclick="checkAll()">Select all</a> |
</pre>

<pre>
<th width="5%">Select?</th>
</pre>

File: app/views/sign_up_sheet/_table_line.html.erb

Add selected checkbox
<pre>
<td><input type="checkbox" name="query_mySelectBox"></td>
</pre>

===2.'Select All' function===
File: app/assets/javascripts/signup.js

Select All function checks all checkbox of topics.
<pre>
function selectAll(source) {
checkboxes = document.getElementsByName('mySelectBox');
for (var i = 0, n = checkboxes.length; i < n; i++) {
checkboxes[i].checked = source.checked;
}
}
</pre>

===3.'Delete' function===
