This website is an online math course. Students can do homework online and submit it for a grade. The problem with this website is that it is not easy to use. For as many students that use this website, it has not been made very user-friendly.
To use this course, one must first register, which is a process that a student cannot figure out without directions. After being registered, the website is divided up into different catagories- homeworks, grades, discussions, help etc. This portion of the website is also very difficult to use.
The reason I know this is because I had to use this website for a course I am taking this semester. Coincidently, the instructors immediately realized the diffuculty that students were having when trying to use this website and they cancelled the use of the website. Instead of turning in homework online, we are forced to go back to turning it in in class.
In comparison with this website, last semester, I used another online math website that was very user- friendly. Students had no problems using this website and it was very successful.
