Modification of JSAV grading

[atilantera]

Could it be possible to modify the JSAV default grader so that it notices if the student has done extra steps after the model answer has finished?

Exercise cases:

• Dijkstra's algorithm (smaller graph components)
• Build-heap (there is a possibility to swap two equal elements in the end)

Notes:

• We could remove some points for student doing otherwise correct simulation but then some extra steps.
• The student should be notified as well for the reason of point reduction.
• This should be done by forking the JSAV repository and modifying it.
• The test server minus.cs.aalto.fi could be used so that even course assistants could do it.
• This might be an easy modification of a couple of lines, but that is an assumption.

TODO:

• Fork JSAV codebase at https://github.com/atilantera/JSAV/
• Clone the JSAV codebase and install its development environment
• Add debug prints to the assumed JSAV default grader function
• Check how to change the grader function in a JSAV exercise
• Design how to make the JSAV grader deliver a custom message to be displayed at the grading process
• odsa-AV.js: display a custom message from the JSAV grader when applicable
• Document the current default grader function
• Integrate development JSAV repo into this https://github.com/Aalto-LeTech/JSAV-exercises testbench (change the git submodule)
• Make a copy of the default grader function with a new name
• Modify the new default grader function
• Test modified grader
• Test display of custom grading messages
• Test with a correct solution: the student should get 100/100 as before

If I remember correctly, the JSAV default grader function is at src/exercise.js:129-165
