English in Teaching and Learning Math in Hong Kong With the intermingling of cultures, business, and globalization in general, it is difficult to imagine that English would not be spoken or at least understood in some form in any part of the world. If nothing else, Internet communication has opened up myriad opportunities for people to learn about any amount of cultures and languages they wish. In terms of business, as mentioned, the world has also become increasingly globalized. Businesses that can expand globally tend to be stronger financially and have greater longevity than those who cannot. Often, an ability to communicate internationally is at the heart of business success. For this reason, the medium of instruction in schools, and especially non-English speaking countries, have come to the forefront of educational attention. In Hong Kong, social and political changes have given a unique dynamic to whether or not English should be used as the medium of instruction in classrooms, including Mathematics classrooms.

A 2005 report by the Education Commission (2005, p. 106) emphasizes the importance of the school environment to help students achieve all-round development, including the enhancement of his or her personal qualities and talents. This means that the medium of instruction in the Math classroom needs to be at a level and of a nature that...

Although political and social changes brought some disagreement on this, it appears that the general consensus is that English would be a more suitable medium of instruction for senior high school and higher education, especially when it comes to complicated subject matter like mathematics.
The Education Commission (2005, p. 106) goes on to state that schools need to cater for the different capabilities and aptitudes of students. Hence, students with a particular aptitude for Mathematics will need to be schooled according to their ability to communicate in the language of instruction. One of the arguments raised for mother tongue instruction is indeed, that students are better able to form complex thoughts about complicated subject matter when they do not need to struggle with the language barrier as well.

For this reason, the Education Commission (2005) recommended using mother-tongue instruction for primary and junior high-school levels. At the same time, however, schools should also enhance the proficiency of students in both Chinese and English. According to the report, schools can choose to use English as medium of instruction depending on various factors, including student ability, the ability of teachers to communicate and teach in English, and the ability of the school to provide measures for supporting English medium instruction effectively and consistently.

Tsui (2008, p. 107) refers to the Education Commission report and its stance that, because Hong Kong is a leading international financial center, its high level of English proficiency needs to be retained. In terms of schools and education, this is particularly important in the Mathematics classroom, since many of the students in these classrooms will enter the financial sector in Hong Kong. Their ability to think about Mathematics and communicate about it in English will ensure the city's ability to remain at the financial forefront not only in the Asian region, but in the world in general. At the same time, as mentioned above, it…
