用英语教初中数学，需要什么水平

To teach middle school mathematics in English, a proficiency level is required that ensures the ability to clearly communicate mathematical concepts and procedures. This involves not only a strong grasp of English language skills but also a deep understanding of mathematical content. The teacher should be able to express mathematical ideas accurately and clearly in English, with a vocabulary that includes mathematical terminology. They should also be able to translate complex mathematical concepts into English for students who may not be native speakers. Additionally, the teacher must be able to use English effectively in classroom management, such as giving instructions, asking questions, and facilitating discussions. Furthermore, they should be familiar with English-speaking educational resources and have the ability to adapt them to the local context. This proficiency might typically require a minimum of an English language proficiency equivalent to an IELTS band score of 7.0 or higher, coupled with a solid foundation in secondary-level mathematics.
