Klausurauswertung (1.5) — Kapitel 1 damit vollständig
Neuer Dialog ExamEvaluationDialog, erreichbar über "Auswertung" im
Klausuren-Tab (Button + Kontextmenü bei ausgewählter Klausur):
- Notenspiegel als Balkendiagramm, Durchschnitt (via bestehendes
GradingService.WeightedAverage), Median, sowie ein Schwellenwert-
Anteil ("< 5/4 Punkte" bei Punktesystem, "nicht ausreichend 5/6"
bei Notensystem 1–6).
- Aufgabenanalyse: durchschnittlicher Erfüllungsgrad je Aufgabe,
auffällig schwache (Ø < 50 %) rot markiert.
- Notenschlüssel verschieben: gleicher Editor wie im Klausur-Dialog,
Änderungen wirken sich sofort im Notenspiegel aus; erst
"Übernehmen" schreibt sie in die Klausur zurück.
- CSV-Export direkt im Dialog, analog zum bestehenden JSON-Export der
Kompetenzkataloge — ohne die noch fehlende Export-Infrastruktur aus
Kapitel 11 vorwegzunehmen.
- Abwesende werden konsequent aus allen Statistiken ausgeschlossen
(löst den in 1.4.3 offen gelassenen Punkt ein).
