Since we have different learning style , we also have to use different teaching style. I think patience is really require in this satuation. We have to listen actively and think of the ideas to how to explain to be able to understand. Use different toung, some student may able to go faster and some are not and we have to make it fare for them. Instead of only let them to listen our explaination we also have to ask questions and let them to presentation oftenly. Give more time if needed.
