Track 欄位語意(重要!)
| 欄位 | 型別 | 語意 | 說明 |
|---|---|---|---|
classes.track | track_type ENUM | 永遠為 NULL | 班級不屬於任何單一 track |
users.track | course_type ENUM | HT 課程類型職責 | LT/IT/KCFS,定義 HT 管理範圍 |
students.track | course_type ENUM | 已棄用 | 設為 NULL,改用 students.level |
courses.course_type | course_type ENUM | 實際課程類型 | LT/IT/KCFS |
courses 表設計
CREATE TABLE courses (
id UUID PRIMARY KEY,
class_id UUID REFERENCES classes(id),
course_type course_type NOT NULL, -- 'LT' | 'IT' | 'KCFS'
teacher_id UUID REFERENCES users(id), -- 可為 NULL(待指派)
academic_year TEXT,
is_active BOOLEAN DEFAULT true
);
工作流程:課程建立(teacher_id = NULL)→ 教師指派(更新 teacher_id)
小學年段系統
年級範圍
- Grade 1 至 Grade 6 (G1-G6)
- 每個年級 14 個班級
- 總計 84 個班級(林口校區)
Level 分級格式
格式:G[1-6]E[1-3]
| Level |
|---|
| E1 |
| E2 |
| E3 |
重要:不同年級的 E1 能力標準不同,只在同年級內比較 Level
資料庫欄位:TEXT 型別,帶 CHECK 約束驗證格式
班級命名格式
G[1-6] [StandardName]
範例:
- G4 Seekers
- G6 Navigators
- G1 Explorers
