Hi, I'm a PhD student here, and my current research topic is about the comparison of music education between England and China. Since I am an international student and haven't stayed here for a long time, I don't know much about music education here, especially the teaching content and pedagogy, etc.. I listed some topics below, could you provide me some information on these as much as possible? I will be very grateful for your help. 1. Are teaching contents in music lessons, which include textbooks or teaching materials, chosen by music teachers? 2. In England, the most common activities in secondary music classes are performing and composing works, is that right? Do students in Key Stage 3 learn some musical theory, history or learn to read music? 3. Do you know whether some music teachers try to integrate 'sustainable development' into music teaching?
