Hello Yen,
If you want to be notified when you post an announcement in your own classes, be sure that you have the "Announcement Created by You" notification option selected in your notification settings. For more information about your notification settings, seehttps://community.canvaslms.com/docs/DOC-13111-4152719738
Every Canvas user has control of their own notification settings, so your students will only be notified about new announcements if they have chosen to receive those notifications in their own notification settings. Instructors do not have any access to or control over their students notification settings, so there's really no way for you to be sure whether or not your students have chosen to receive notifications about new announcements.
