Project Description

While setting up an assignment, the instructor will be asked to choose different kinds of rubrics. Any of these rubrics can later be edited or changed to a different rubric. A problem arises when an assignment is underway (students have already started reviewing) and a rubric is edited or changed. Some students started reviewing with the old rubric and the rest of the students who had not started a review will be presented with the updated rubric. This usually happens when an assignment is copied from a previous year and the rubrics are not updated to match the current topic. It could be at a later point that the instructor/TA realizes this and changes it.

Goal

If the instructor does edit or change a rubric while an assignment is in progress:

• If the change affects only the wording of a particular rubric item (e.g., to clarify the statement), no action is necessary.
• If a rubric is replaced, or the items/questions are changed, then all the reviews that have been done need to be redone. The system should then email the previously done reviews to the reviewer and delete the response object and all associated answer objects. (However, the response_map should not be changed.)

This project was done in Fall 2019. However, it was not tested thoroughly. Our team's work in Spring 2021 is to improve the testing and readability of the code.

Proposed Solution

We will write comprehensive tests and fix any bugs in the code written already for changing rubrics while projects are in progress.

Some known issues already have been identified:

• Email functionality needs to be thoroughly tested
  • Currently, only tested for correct arguments

• The method find_review_period is possibly redundant as Find deadlines does exist already in the code. This method needs to be replaced/removed if possible

• A method comment is needed on in_active_period method in answer_helper.rb

• Tests need to be more thorough and verify that correct rows are being deleted for delete_existing_responses function in answer_helper.rb

• Split delete_existing_responses into more functions as it's complexity is reletively high
  • Contains some nested loops so these should be removed

• Confirm changes do not affect students who have not yet submitted their reviews by doing UI testing

• Line-by-line comments are needed for all added functions
