Eduardo,
You ask a lot of good questions!
1. One of the best ways to improve your speaking is to find
opportunities to speak with other English speakers, including other
English students. One of the biggest improvements in speaking ability
among my classroom students came several years ago when I began to use
a lot of cooperative learning, small group learning. Two things
happened: they began to think of themselves as English users, not
English students (a very important idea). Second, since the other
members of the group were "junior" users like themselves, they relaxed
and the psychological barriers to improving their English began to
disappear.
Formal, structured practice does not help much. Using English for real
communication does, even if it is very simple communication at first.
That's why groups like this are important. If I could wave a magic
wand, the members of this group would have long, extended discussions,
either here or during Skypecasts about all kinds of interesting
subjects. When that happens, as you realize with your writing, you
become comfortable and confident using the English you have acquired
by reading and listening.
One personal experience: I have been working with a Taiwanese graphic
artist for about 9 months. We meet 30 minutes a week, and talk about a
book or articles we read during the week. Mostly we talk about ideas;
occasionally I explain a grammar point to help her better understand
something. In the 9 months, her confidence and comfort using English
has increased tremendously. This is the kind of practice I am talking
about. It's the same approach I use in the classroom.
2. About the TOEFL
First, I believe that the iBT TOEFL is a very good indication of a
student's preparation for American academic English. It is much better
than the paper- or computer-based TOEFLs.
Second, it's very difficult to answer your question about the level of
fluency required. Perhaps the best way to find out if your English
ability is good enough is to sign up at the ETS web site -
www.ets.org
- to take the practice TOEFL that they offer.
The most common problem I see and that I hear about is not enough
general English ability, the kind that comes from real exposure to the
language, which is another way of saying not enough reading and
listening. I wish that students and teachers fully understood the
importance of this.
As a very rough estimate of English ability, I would say that if you
can understand a variety of lectures from iTunes U and read and
understand some of the magazines that I have marked "Advanced" on my
Online Reading and Listening page -
http://www.successfulenglish.com/Successful_English/Online_Reading_%26_Listening_for_English_Learners.html
- you are probably ready, or very near. Again, this is a rough
estimate.
This is too long! I must stop. Let me know if you have any other
questions.
