What language teaching platforms do you know?
There are many variants nowadays, even free, but I recommend to use professional software. The result will be much better. For example we use SmartClass+ language teaching platform, it helps us to improve students’ speaking and listening skills and motivate them. It’s a pleasure to work with such system.
