教師と生徒を管理する

生徒と教師は、ユーザー プロフィールとコースとの間の固有のマッピングであり、コースでのユーザーのロールを表します。生徒と教師の指定はグローバルではありません。1 人のユーザーをあるコースでは教師として、別のコースでは生徒として割り当てることができます。「生徒」または「教師」の指定は、特定のコース内の特定のユーザーに対する一連の権限を表します。

学生
学生リソースは、特定のコースに学生として登録されているユーザーを表します。生徒はコースの詳細と教師を閲覧できます。
教師
教師用リソースは、特定のコースを教えるユーザーを表します。教師は、コースの詳細の表示と変更、教師と生徒の表示、追加の教師と生徒の管理を行うことができます。

生徒と教師は、Directory API から返されるユーザーの一意の ID またはメールアドレスによって識別されます。現在のユーザーは、短縮形 "me" を使用して自分の ID を参照することもできます。

直接追加

ドメイン管理者は招待フローを回避して、ドメイン内のユーザーを教師または生徒としてドメイン内のコースに直接追加できます。コースのオーナーが管理者のドメイン内にある場合、コースは管理者のドメイン内にあるとみなされます。認証されたドメイン管理者のドメイン外のユーザーまたはコースの場合、アプリケーションは invitations.create() メソッドを使用して招待状を送信し、ユーザーの同意を得なければなりません。

教師を追加または削除する

ドメイン管理者は、次のサンプルに示すように、teachers.create() を使用してドメイン内の教師をコースに直接追加できます。

認証された教師に代わって生徒を追加する場合は、invitations.create() メソッドを使用する必要があります。

コースから生徒を削除するには、students.delete() メソッドを使用します。これにより、指定した学生がコースから削除するだけで、他のコースへの登録やユーザー プロフィールには影響しません。

ユーザーのコースを取得する

生徒または教師のコースのリストを取得するには、courses.list() を呼び出し、対応するユーザーの studentId または teacherId を指定します。

ユーザーのプロフィールを取得する

ユーザーの ID と名前を含む要約されたプロフィールを取得するには、ユーザーの ID、メールアドレス、またはリクエストしているユーザーの「me」を指定して userProfiles.get() を呼び出します。

emailAddress フィールドを取得するには、classroom.profile.emails スコープを含める必要があります。

返される ID は、一致する studentId または teacherId を含む Directory API Users リソースに対応しています。

コースのオーナーを管理する

ドメイン管理者は教師間でコースのオーナー権限を譲渡できます。重要な詳細については、コースのオーナー権限を譲渡するをご覧ください。
