Learn English the Easy and Fun Way

I have been a teacher for 27 years. I mainly teach Science in elementary and in high school. I have taught Science using English as a medium of instruction. I have also taught Social Studies to Korean students using English as a medium. I also worked as an academic supervisor first, as a Science coordinator for four years then as the assistant principal for academics. I also taught for one year and one month in New Mexico, USA -first as an on-call substitute teacher from pre-school to high school, then as a middle school Science teacher. I have undergone training in ESL teaching.
