I like very much teaching, as could be seen from my profile.
I agree mostly with Communicative Language Teaching Approach.
That is, I consider that the key to a proper language acquisition is interaction.
My lessons consist thus of making students construct sentences by themselves, and making students listen to a lot of dialogues.
From the point of view of the grammar, I find that ability to conjugate verbs and use them with nouns in correct declinations are highly important. So, I try to control the learning by heart of the most important verbs by students.
I usually use one basic textbook, and one collection of audio tracks. And I prepare complementary materials for each session.
