Your blog beautifully presents your work this quarter!  The use of font, color and formatting of your posts creates a very readable blog.  The organization is also well done. Here are some final comments.
Introduction
Good revisions to your introduction.  Let me comment on a few additional changes that need to be made:

I'm Carmen Wong. I really like Foothill online classes. This is the forth fourth or fifth online class that I've been taken at Foothill College, but this English online class is the my first. Most of the online classes that I had taken before were technical and programming classes.

I like taking online classes because I don't like to commute, especially during the rush hour. I also like the flexibility that I don't have to be in class at certain time. However, taking an online class requires a lot of self motivation and discipline. I think Etudes has done a great job in helping to help student students to keep track of schedule, deadline deadlines, and grades.

I had taken some ESL classes about fifteen years ago. I'm taking this class to refresh on my English grammar. From all the students' posts, it sounds like as though Miss Rita is a great ESL instructor.  I'm looking forward to learn learning a lot from this class and from every one.

Language Research

Based on my research, "concern about" means "worry about" like, I'm concerning concerned about my mother's health. "Concern with" means worry about an issue like, My biggest concern with the economy is the slowness of the house market.
