Co-teaching with international school teachers have been very common for Taipei Municipal Zhongzheng Senior High School. Take our sister school Moreton Bay College in Australia as an illustration.  Our local math teacher, Mr. Kai Deng, has been working with Mr. Brendan Miles online to guide our students from Bilingual Experimental Class 118 to learn how to calculate distances on the Earth's surface. Mr. Miles first guides the students to calculate the distance between two cities based on the coordinates of the world map and the perspective of the earth. In addition to detailing formulas for mathematical calculations, Mr. Miles also gives the students hands-on tasks to practice calculations online and interact with Class 118. This type of intercultural academic learning is a mind-blowing experience for the students.
