Development:Gradebook 2.x architecture
From MoodleDocs
This page summarizes some initial ideas and suggestions that may help to resolve Stage 3 of the Gradebook improvements project.
Current issues
These are some of the most important issues with the current Gradebook design that this spec tries to deal with. See http://www.mindmeister.com/89537697/gradebook-2-x-issues-braindump for even more issues.
- The grades appear in the gradebook immediately (MDL-25439)
- The grade values are stateless. We need a way how to store grades in the gradebook but exclude them from aggregations yet. Currently, the hiddenuntil feature tries to solve this but it is pretty limited and hacky (MDL-25440).
- Students and teachers may see different values
- Because of how grades hiding is implemented currently, it is practically impossible to pre-populate whole grades tree and/or export reliable data (because they are dependent on the current role permissions).
- Unable to alter grades processing
- There is a demand for alternate methods of grades processing (eg grades over 100% or negative grades) due to local conventions in various countries and school systems.
- Grading logic and UI implemented in activity modules
- Grading tools like single point grade, scale-based grading or a new rubric-based grading should be handled by the Gradebook core with a rich set of interface toward activity modules (and eventually other plugin types).
- Manual and auto grades interaction
- What should happen in this scenario has never been defined: 1. Student makes first attempt at the quiz, gets grade of 50%, this is pushed to the gradebook. 2. Teacher manually edits the grade to be 60%. 3. Student makes second quiz attempt and scores 75%. What should the gradebook show now?
