I have 19- year working experience in teaching foreign languages. I have an internet site with lots of learning materials. During the lessons, I primirely concentrate on the structure of the language and reading texts (with full understanding ) . Just knowing very simple grammar rules makes it possible to build your own sentences correctly, hence making communication possible. As for vocabulary... all one needs is a good dictionary (there are many very good on-line dictionaries available in the internet). I sent my students files (in pdf- format) containing common Russian words to let them practice making they own centences using specific grammar structures. I use different kinds of exercises to get those structures and words into long- term memory. My goal is to make my lessons useful to students.
Absolute beginners start off making very easy sentences. Once they are able to do it, they begin to make the sentences more complicated.
To illustrate my point, I wrote a few sentences in English:
1. They read.
2. They read books.
3. They read books every day.
4. They read interesting books every day.
5. They read interesting books every day when they come from work.
6. They read interesting books every day when they come from work unless they are tired.
7. They read interesting books every day when they come from work unless they are very tired.
If you are interested in learning Russian these way, please book a lesson.
