Project: TAskmaster

TAskmaster is a desktop app for managing students, optimised for use via a Command Line Interface (CLI) while still having the benefits of a Graphical User Interface (GUI). If you are a CS Teaching Assistant who can type fast, TAskmaster can help you track your students’ attendance and class participation faster than traditional GUI apps.

Given below are my contributions to the project.

  • New Feature: Storage for Attendance
    • This feature was replaced by the feature below, also developed by me.
  • New Feature: Storage for SessionList
    • What it does: saves the SessionList of the Taskmaster to a file every time it is modified; the SessionList is then loaded from the file on startup.
    • Justification: This feature is essential for practical use of the application as it is expected that a user will not have it open all the time, but would still want to save their records when closing and reopening the app.
    • Highlights: This enhancement required an good understanding of existing Storage code to convert SessionList classes to their Json representations. Significant modification to existing test code was also done (especially in TypicalStudents.java)
    • Credits: The design of this feature were adapted from existing Storage code.
    • Additional details of the implementation are here
  • New Feature: LowestScoreCommand
    • What it does: in a Session, displays all the students with the lowest class participation score
    • Justification: This feature is useful for TAs, especially if they have classes with many students and cannot afford to scroll through their list to call a student who does not have class participation.
    • Highlights: This enhancement required a substantial refactoring of Model code as the ObservableList<StudentRecord passed to the UI was previously not modifiable (to set a predicate). The change of the relevant field in Model triggered a few errors that had to be fixed in a methodical manner. Testing of code was required to uncover the problem, which was that the list of student records was not updated in time before being called by the UI. This occurred when the relevant listener was activated upon the changing/adding of a Session to the Taskmaster. Fixing this issue required significant modifications to how the representation of the StudentRecordList was handled by the Model class.
