It took a while to make up my mind and collect information, but in February 2016 I started applying for several schools around the globe. Here is the list until April 2016:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\">Taiwan, Taipei<\/li>\n\n\n\n<li class=\"has-medium-font-size\">China, Shanghai Pudong<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Egypt, Hurghada<\/li>\n\n\n\n<li class=\"has-medium-font-size\">India, Mumbai<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Vietnam, Saigon or Ho Chi Minh City<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Indonesia, Jakarta<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Turkey (now T\u00fcrkiye), Ankara<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Russia, Moscow<\/li>\n<\/ul>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">I added my resume to the database. Offers from Belgium and Mexico reached me by email.<\/p>\n\n\n\n<h2 class=\"wp-block-heading is-style-text-subtitle is-style-text-subtitle--5\" id=\"teaching-in-the-english-language---5-years\">Teaching in the English language &#8211; 5 years<a href=\"https:\/\/kreier.github.io\/saiht-blog\/html\/2025\/10\/18\/#teaching-in-the-english-language---5-years\"><\/a><\/h2>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">My teaching degree brought me to Saigon in Vietnam, but I only taught for 1 year in German. After that I worked 3 years for the&nbsp;<strong>American International School Vietnam<\/strong>&nbsp;and 2 years for the&nbsp;<strong>Saigon South International School<\/strong>. The topics span a variety of subjects and include the American curriculum, IB Diploma Program and AP Advanced Placement. For the IB and AP I received special training. Here is a list:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\">IB Physics HL\/SL (training in Jakarta)<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Chemistry<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Integrated Science 9\/10 (biology, chemistry and physics)<\/li>\n\n\n\n<li class=\"has-medium-font-size\">MYP Design (training in Bangkok)<\/li>\n\n\n\n<li class=\"has-medium-font-size\">AP Physics A (training in Sacramento)<\/li>\n\n\n\n<li class=\"has-medium-font-size\">High School Math<\/li>\n\n\n\n<li class=\"has-medium-font-size\">AP CSP Computer Science Principles (training in Baltimore)<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Live Science<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Advanced Automation<\/li>\n<\/ul>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">From a certain perspective I was successful with my teaching. In IB Physics at the AISVN we never had an SL student receive 6 points, and only one time in the past a student had received 6 points on HL higher level. No one ever got 7 points. I wanted to change that.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">My first 2-year course started in 2018, and the results of 2020 were remarkable. All 15 students passed, both SL and HL. And some students received 6 and 7 points as their IB score, both HL and SL. Usually the best subject at AISVN is&nbsp;<em>IB Vietnamese Literature<\/em>&nbsp;with an average slightly above 6 points, and for obvious reasons. But in 2020 the best subject was&nbsp;<strong>IB Physics HL<\/strong>&nbsp;with an average of&nbsp;<strong>6.5 IB points<\/strong>! Two students scored 6 points, two students scored 7 points. I am very proud of my students!
