CSC/ECE 517 Spring 2023 - E2320. Reimplement the Question hierarchy

Expertiza

Expertiza is a Ruby on Rails based open source project. Instructors have the ability to add new projects, assignments, etc., as well as edit existing ones. Later on, they can view student submissions and grade them. Students can also use Expertiza to organize into teams to work on different projects and assignments and submit their work. They can also review other students' submissions.

Question Hierarchy

The Question class and its subclasses are used to implement all rubric items, quiz questions, and survey questions in Expertiza. Here is the hierarchy.

Choice question

  Scored question
   Scale [√]
   Criterion [√]
  Unscored question
   Dropdown [√]
   MultipleChoice
   CheckBox [√]  [should this be a Scored question?}

TextResponse

   TextArea [√]
   TextField [√]

UploadFile [√]

Problem Statement

Dropdown, MultipleChoice, and Scale questions have a lot in common: you display the alternatives and let the user choose one of them. They also differ, in that only Scale is required to have a numeric sequence of choices; Dropdown and MultipleChoice may, but also may have selections that don’t correspond to anything numeric. We would like to write a single piece of code to display all three types of questions

Files Modified

Below are the files we changed as part of the reimplementation

question.rb scale.rb criterion.rb text_area.rb text_field.rb text_response.rb questionnaires_controller.rb answer.rb checkbox.rb choice_question.rb dropdown.rb multiple_choice_checkbox.rb multiple_choice_radio.rb question.rb question_advice.rb questionnaire.rb quiz_question.rb quiz_question_choice.rb scored_question.rb unscored_question.rb

Reimplementation

As a part of the reimplementation project, Migrations are created, added relevant old code files and partials are included in the old code files to avoid HTML concatenation.
