My only regret is not doing TEFL @ TIES sooner ...

What an amazing experience!
First, I had to unlearn - parting with the traditional way of teaching/facilitation. It was difficult. I shed tears. Lots of them.
But Tania Copeland and Jan de Klerk guided my thoughts, attitude and actions towards teaching English as a foreign language - thorough instruction, strong support, lots of encouragement. After long hours of hard work I can say this was 1 of the top 5 experiences in my life. The International English School provided me with a thorough practical toolbox to teach in any place in the world.
