Our Fall I 2011 MAT115 hybrid course, came to a halt with the Holiday break. 

We will be coming back soon with yet another exciting semester of posts and lots of Math Love!

Best- Professors Meangru & De Leon

I will start this review of this Hybrid course, by mentioning that to me, first of the description is misleading and since the class is run in a completely different manner than other Math 115 sections, it should also be advertised as one.

The mere term Hybrid, is extremely broad and doesn’t give a student who is registering for this class an outlook on the way this class will be conducted. As a person who has struggled with math from an early academic age, I would have benefited from a course in which I had more class time, all materials was first taught in class and not sectioned off between lessons in class and lessons on educosoft, and more. While professor Meangru, is doing an excellent job, it is my firm belief that this style of course needs a lot of improvement, in the area of advertisement.

I am aware that math 115 is considered rudimentary college beginner’s math, and that most students who took this class with a prior math knowledge or at least not impaired, benefited from its easy (once a week) schedule, and are more than satisfied to pass this course, get the credits, fulfill their major requirements and move on, without much time spent in.

This is all great, where it works, in the areas where it doesn’t work, like in my case, I would suggest some changes are in need.  Other than my frustration in general with math, which by this point, must be obvious, I will repeat, that professor Meangru, has been great and this class could have been run a lot worse if it weren’t for him running it. 

Thank you.
