What is a Course Hub?

Welcome! This website, the MAT 1275 Course Hub, is a central location for information and resources related to MAT 1275 College Algebra and Trigonometry. Whether you are a student in the course or a faculty member teaching it, we hope you will find useful material here.

How is this site different from my own section on OpenLab or Blackboard?

This is a department-wide site with general resources for everyone taking the course. You can use it as a reference or for support, but it is not the right place to leave messages for your professor or classmates. Your professor can let you know how to find your section online on OpenLab or Blackboard.

Faculty, if you’re interested in using the OpenLab in your section, please check out the online module on getting started with Model Courses.

How you might use this site (Students)

  1. If you miss a class.  Read and watch the Lessons for the topic that was discussed that day (and of course write down your questions and do the homework problems).  Look at the Video Resource Guide for additional videos arranged by topic. To find out what you missed, ask a fellow student or consult the syllabus.
  2. To learn about the course before you take it. Look at the Course Outline, check out one or two of the Lessons, and explore the other resources to get a sense of what the class will be about.
  3. To prepare for a class.  Repeated exposure is necessary for learning.  Read and watch the Lessons for the topic that will be covered in class that day before going to class, writing down your questions as you go.  During class, follow the lecture and ask your questions where appropriate, or in a flipped class, ask questions either of your group during class or of the professor at the start of class.
  4. To review for an exam.  Check out the Review materials. Visit the Video Resource Guide to brush up on topics. Look at the annotations to see which problem types you are struggling with the most.  Don’t waste time re-watching videos on topics you have already mastered: if you can correctly do the problems, watch something else.

If you ever feel like you’re working hard and still not getting the results you want, please read these Notes for Students.
