While I cannot offer you a TESOL certificate, I have been training teachers since 2007. I have conducted many TESOL certification courses for Oxford Seminars as well as CIEE, and I have also taught TESOL students at the university level at a large education university in Malaysia. Moreover, I have conducted many teacher-training workshops and presentations in various countries.
In our lessons, we can cover topics such as teaching grammar, teaching pronunciation, best practices for online language instruction, maximizing educational technology resources, etc.
