One of the most common ways for an instructor to communicate with the entire class at once is by posting an announcement on the MSJC Content Managment System (CMS). Once you log on to http://my.msjc.edu (aka Blackboard) you should see a list of all of the courses you are enrolled in for the current semester. Underneath the title of each course is where any announcements for the course are displayed - if any have been posted by your teacher. If there are no new announcements the text will read "No announcements posted."
It only takes a second to logon to my.msjc.edu and just a couple of minutes to check for any announcements that you may have been sent from any of your instructors. You should make it a habit of checking both your MSJC email and online announcements at least once per day, Monday through Thursday, and at least once again over the weekend. That way you are always informed of the most recent updates sent to you from your MSJC instructors. Being an informed student increases your ability to be a successful scholar.
