I have seen it, and I can tell you 100% that this does not require knowledge of computer-related majors. Many students are not computer majors. This is mainly about software applications. Simply put, it is to teach you how to use all kinds of software in practical teaching. My suggestion is that unless you are familiar with or interested in this field and want to develop in this field, you'd better choose this one. If you want to be a teacher, you can study medicine (ITE), which is more educational.
As for employment, this major has not yet developed in China, so if you want to make a living by this major, you should either continue to study for a doctorate or go to Hong Kong or abroad to find a similar job.
