About Curriculum and Textbooks

I want to write something about little differences of between American and Chinese elementary schools. Would you help me to check it out? Thank you very much!

In the United States, each school/school district develops its own curriculum and learning materials based on the state GLCEs and common cores. There are no nation-wide nationwide or state-wide statewide textbooks. Schools/districts have their own choice of which supplementary books they want to use.
There are several benefits for this:
• Teachers have more choices of what learning materials can best serve for their teaching.
• Learning and teaching become more creative.

In China, there are national curriculum and even textbooks for all the students. It is allowed that for some provinces to develop their own curriculums and textbooks. At least in the same province, students hold use the same textbooks at least in the same province.
There is a group of professors who work together to develop the learning materials, including students’ textbooks, teachers’ guides, and students’ workbooks, etc. It depends on the different schools if they want the teacher’s guides or students’ workbooks, but students’ textbooks are a must for each students student.
There are several benefits for unified textbooks:
• It helps teachers to saves save a great amount of time to prepare for a class.
• If a student transfers to another school in a province, he/she can just bring the textbooks because that they will be just the same. It is not totally a new situation for them academically.
