I have a huge experience more than 20 ching is my job and i worked in many schools,and gave online classes,too.If you want to be a good language teacher,you have to know what are the needs of your the other side, language is grammar,vokabular,comprehension,and that all must be included in the teaching.I like to give a topic which we can discuss during the class,or listening parts which must be learnt,but it can be done through our conversation,or through many excercises.All in all i don't like boring classes,you have to be active,too and that is the way you can be successful at aquairing a new language.I like when a student ask,that means he or she is eager to understand ,to learn the language.
