His enthusiasm for Technology to enhance learning includes new developments in facilitating the introduction of a 1-to-1 iPAD program and is looking forward to the introduction of 3D printer technology within the Design Technology department at his current school.

Economics: Matt McGee

Matt has a background similar to that of many OSC students: of Irish-American heritage; born in Ecuador, raised in the West Indies, Latin America, Greece and Sweden…and now teaching at SCIS in Shanghai, China. After many years at Uppsala University in Sweden getting two masters degrees he slipped into teaching much by accident. He started teaching IB Economics is Sweden in 1996 and when several ex-students pointed out that they were selling all his economics notes to first year students in UK universities, he started writing the first edition of his IB Economics textbook “The Good, the Bad and the Economist.” Having been with OSC since 2002 teaching on the Spring and Summer IB courses he is, in his own words, “pretty much OSC inventory”.

Matt spends a good portion of his off-time in Shanghai following economic trends and looking at data – all his students get to hear “…look it up!” at least once during every class. This, together with the on-going economic development in Asia and OSC expansion in Shanghai, quite naturally led him to his present post here on the Economics blog. He reminds us, in the words of John Maynard Keynes, that nothing is beyond the interest and sphere of the economist, whereby students are encouraged to write to him with suggestions!

    Hello, Sundeep.

    This is not the best spot for talking about TOK. May I redirect you to my blog TOK meets global citizenship? There, you’ll see comments on TOK and resources and can make comment on any specific postings.
