I am sure that every lesson should be unique and engaging, and depends on the student's aims and requests. That's why it’s my high priority to discuss everything in advance about what the students expect after study.
I pay much attention to speaking as it’s extremely inspiring when you realize that you can express your ideas and thoughts in another language. And that’s the reason why I don't want to dive into linguistics, I want to teach the language that everyone can use in everyday life.
Language is a system, we cannot avoid rules and study some grammar and new vocabulary. But studying relevant topics and expressions can make it easier. As we don’t want our students to be bored during the lesson and study an out of fashion language.
And I highly recommend using the app for daily practice. I can definitely say that it’s a very effective way of studying according to my own experience.
