CSC/ECE 517 Fall 2020 - E2071. Improve assessment360 controller.rb

This wiki page is for the description of E2071. Improve assessment360 controller.

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

As an instructor, you are able to view tables with information on student performance across the various courses they are taking and their assignments. Currently, these tables always show the same information and you are not able to specify if you only want to see certain data. Furthermore, the source code has some variables names that are not clear to what their purpose is in the code.

To fix the problem:

1.There should be a dialog that appears before navigating to the pages where the table views are that contain a list of checkboxes to allow the user to choose which columns they would like to see.

Course Grade Summary

Selectable columns:

• Instructor Assigned Scores
• Peer Grades
• Topics

View Aggregated Teammates and Meta Reviews

Selectable columns:

• Teammate Review Scores
• Meta Review Scores
• Number Of Teammates

Solution

1.Modify View

File: app/views/tree_display/_dialog.html.erb

This file is a ruby view partial that contains the html for the checkbox dialogs.

<div id="dialog_course_summary" title="Select Columns" hidden="true"> 
    <%= form_tag('/assessment360/course_student_grade_summary', method: :get) do %>
        <div class="form-group row" style="margin-bottom: 0px !important;">
            <%= label_tag('InstructorAssignedScores', "Instuctor Assigned Scores") %>
            <%= check_box_tag 'fields[]', 'InstructorAssignedScores'%>
        </div>
        <div class="form-group row" style="margin-bottom: 0px !important;">
            <%= label_tag('PeerGrades', "Peer Grades") %>
            <%= check_box_tag 'fields[]', 'PeerGrades'%>
        </div>
        <div class="form-group row" style="margin-bottom: 0px !important;">
            <%= label_tag('Topics', "Topics") %>
            <%= check_box_tag 'fields[]', 'Topics'%>
        </div>
        <%= hidden_field_tag('course_id', '', :id => 'course_summary_course_id')%>
        <%= submit_tag("Submit") %>
        <button type="button" id='closeCourseSummaryDialog'>Close</button>
    <% end %>
</div>
<div id="dialog" title="Select Columns" hidden="true"> 
    <%= form_tag('/assessment360/all_students_all_reviews', method: :get) do %>
        <div class="form-group row" style="margin-bottom: 0px !important;">
            <%= label_tag('TeammateReviewScores', "Teammate Review Scores") %>
            <%= check_box_tag 'fields[]', 'TeammateReviewScores'%>
        </div>
        <div class="form-group row" style="margin-bottom: 0px !important;">
            <%= label_tag('MetaReviewScores', "Meta-Review Scores") %>
            <%= check_box_tag 'fields[]', 'MetaReviewScores'%>
        </div>
        <div class="form-group row" style="margin-bottom: 0px !important;">
            <%= label_tag('NumberOfTeammates', "Number Of Teammates") %>
            <%= check_box_tag 'fields[]', 'NumberOfTeammates'%>
        </div>
        <%= hidden_field_tag 'course_id'%>
        <%= submit_tag("Submit") %>
        <button type="button" id='closeDialog'>Close</button>
    <% end %>
</div>

File: app/assets/javascripts/tree_display.jsx

Added functions to toggle dialog.

  
  if (document.getElementById('closeDialog')) {
    document.getElementById('closeDialog').onclick = () => {jQuery('#dialog').dialog('close')};
  }
  if (document.getElementById('closeCourseSummaryDialog')) {
    document.getElementById('closeCourseSummaryDialog').onclick = () => {jQuery('#dialog_course_summary').dialog('close')};
  }


   toggleModal: function() {
     jQuery( "#dialog" ).dialog();
     document.getElementById('course_id').value = parseInt(this.props.id/2).toString();
   }
   toggleCourseSummaryModal: function() {
     jQuery( "#dialog_course_summary" ).dialog();
     document.getElementById('course_summary_course_id').value = parseInt(this.props.id/2).toString();
   }

Added buttons to replace links that trigged dialog popups.

<button title="View grade summary by student" onClick={this.toggleCourseSummaryModal} 
style={{"padding": "0px", "margin": "0px", "border": "0px", "width": "24px", "height": "24px", "top": "8px"}} >
  <img src="/assets/tree_view/360-dashboard-24.png" />
</button>

<button title="View aggregated teammate & meta reviews" onClick={this.toggleModal} 
style={{"padding": "0px", "margin": "0px", "border": "0px", "width": "24px", "height": "24px", "top": "8px"}} >
  <span style={{"fontSize": "22px", "top": "8px"}} className="glyphicon glyphicon-list-alt"></span>
</button>

File: app/views/assessment360/all_students_all_reviews.html.erb, app/views/assessment360/course_student_grade_summary.html.erb

Added conditionals to show selected columns for the html tables

  <% if @show_meta_reviews%><% total_meta_review_count = @overall_meta_review_count.inject(0) {|sum, (k, v)| sum + v } %><%end%>
  <% if @show_meta_reviews%><td><%= "#{total_meta_review_grade / total_meta_review_count}%" %></td> <%end%>
  <% if @show_teammate_reviews%><% total_teammate_review_grade = @overall_teammate_review_grades.inject(0) {|sum, (k, v)| sum + v } %><%end%>
  <% if @show_teammate_reviews%><% total_teammate_review_count = @overall_teammate_review_count.inject(0) {|sum, (k, v)| sum + v } %><%end%>
  <% if @show_teammate_reviews%> <td><%= "#{total_teammate_review_grade / total_teammate_review_count}%" %></td> <%end%>

2.Modify Controller

File: app/controllers/assessment360_controller.rb

Added Variables to check if corresponding columns should be shown.

    fields = params[:fields]
    @show_meta_reviews = fields.include? 'MetaReviewScores'
    @show_teammate_reviews = fields.include? 'TeammateReviewScores'
    @show_teammate_count = fields.include? 'NumberOfTeammates'
    @colspan_count = 2
    if !@show_teammate_reviews
      @colspan_count -= 1
    end
    if !@show_meta_reviews
      @colspan_count -= 1
    end

3.'Updated Variable Names

File: app/controllers/assessment360_controller.rb

Renamed @teamed_count to @total_unique_teammates

  @total_unique_teammates = {}

Modify course_student_grade_summary

File: app/controllers/assessment360_controller.rb

Added ability to calculate average peer review score for each student in a course.

   @average_peer_review_score = {}

...
        next if peer_review_score.nil? 
        next if peer_review_score[:total_score].nil?
        @average_peer_review_score[cp.id] += peer_review_score[:total_score].round(2)
      end
      if @assignments.count > 0
        @average_peer_review_score[cp.id] = (@average_peer_review_score[cp.id] / @assignments.count()).round(2)
      end

Result

Before navigating to aggregated teammate and meta reviews, a dialog shows to allow the user select which columns they would like to see.

Similarly, before navigating to course grade summary, another dialog shows to allow the user select their columns.
