# LehrerApp-Austauschformat: Unterrichtseinheit
|
||||
|
||||
Dieses Dokument beschreibt Version 1 des JSON-Formats `lehrerapp.unit-planning`.
|
||||
Es dient zum Austausch einer vollständigen Unterrichtseinheit einschließlich ihrer Stunden.
|
||||
|
||||
## Grundregeln
|
||||
|
||||
- Die Datei enthält reines UTF-8-JSON. Beim Import wird auch ein einzelner Markdown-Codeblock akzeptiert.
|
||||
- Datumswerte verwenden `JJJJ-MM-TT`, Uhrzeiten `HH:MM` oder `HH:MM:SS`.
|
||||
- Statuswerte sind `planned`, `active`, `completed` für Einheiten und `planned`, `conducted` für Stunden.
|
||||
- Interne IDs werden nicht übertragen. Der Import legt eine neue Einheit und neue Stunden in der aktuell geöffneten Lerngruppe an.
|
||||
- `context` hilft bei der Bearbeitung mit einer KI, wird beim Import aber nicht zur Zuordnung verwendet.
|
||||
- Unbekannte zusätzliche Felder werden ignoriert.
|
||||
|
||||
## Beispiel
|
||||
|
||||
```json
|
||||
{
|
||||
"schema": "lehrerapp.unit-planning",
|
||||
"version": 1,

|
||||
|
||||
## Felder
|
||||
|
||||
### Dokument
|
||||
|
||||
- `schema` (Pflicht): exakt `lehrerapp.unit-planning`
|
||||
- `version` (Pflicht): aktuell `1`
|
||||
- `context` (optional): `group`, `subject`, `gradeLevel` und optional `unitTitle`
|
||||
- `unit` (Pflicht): die zu importierende Einheit
|
||||
|
||||
### Einheit
|
||||
|
||||
- `title` (Pflicht, Text)
|
||||
- `startDate`, `endDate` (optional, Datum oder `null`); das Ende darf nicht vor dem Start liegen
|
||||
- `competencies` (Liste von Kompetenzcodes oder Freitexten)
|
||||
- `status` (optional, Standard `planned`)
|
||||
- `notes` (optional, Text oder `null`)
|
||||
- `lessons` (Liste, darf leer sein); Aufbau siehe Stundenformat unten
|
||||
|
||||
### Stunde
|
||||
|
||||
- `date` (Pflicht, Datum)
|
||||
- `lessonNumber` (optional, Ganzzahl 1–20 oder `null`)
|
||||
- `topic` (Pflicht, Text)
|
||||
- `startTime` (optional, Uhrzeit oder `null`)
|
||||
- `status` (optional: `planned` oder `conducted`, Standard `planned`)
|
||||
- `homework`, `reflection` (optional, Text oder `null`)
|
||||
- `phases` (Liste, darf leer sein)
|
||||
|
||||
### Phase
|
||||
|
||||
- `name`, `activity`, `material`, `shorthand` (Text; leere Werte sind erlaubt)
|
||||
- `durationMinutes` (Ganzzahl 0–180)
|
||||
- `alternativePath` (optional): lesbarer Name eines alternativen Verlaufs, z. B. `Kurzversion`. Beim Import wird ein vorhandener gleichnamiger Ablauf verwendet oder neu angelegt.
|
||||
|
||||
## Hinweise für KI-Bearbeitung
|
||||
|
||||
- JSON-Struktur, `schema` und `version` unverändert lassen.
|
||||
- Nur gültige ISO-Daten verwenden.
|
||||
- Phasendauern so wählen, dass ihre Summe zur verfügbaren Unterrichtszeit passt.
|
||||
- Keine IDs ergänzen; Beziehungen werden beim Import automatisch hergestellt.

# LehrerApp-Austauschformat: einzelne Stundenplanung
|
||||
|
||||
Dieses Dokument beschreibt Version 1 des JSON-Formats `lehrerapp.lesson-planning`.
|
||||
Es dient zum Austausch genau einer Stunde mit ihrem Verlaufsplan.
|
||||
|
||||
## Grundregeln
|
||||
|
||||
- Die Datei enthält reines UTF-8-JSON. Beim Import wird auch ein einzelner Markdown-Codeblock akzeptiert.
|
||||
- Datum: `JJJJ-MM-TT`; Uhrzeit: `HH:MM` oder `HH:MM:SS`.
|
||||
- Interne IDs werden nicht übertragen. Der Import legt eine neue Stunde in der aktuell ausgewählten Einheit an.
|
||||
- `context` ist nur Bearbeitungshilfe und entscheidet nicht über das Importziel.
|
||||
- Unbekannte zusätzliche Felder werden ignoriert.
|
||||
