Giáo viên Mỹ phải bỏ tiền túi để mua sắm đồ dùng trong lớp

January 15, 2015 Lawrenceville - Andy Dugger (standing), listens to presentation during his AP US History class at Central Gwinnett High School in Lawrenceville on Thursday, January 15, 2015. Some Gwinnett County residents say the school district's history courses, particularly Advanced Placement U.S. History, do not properly reflect many moments and people in American history and much of it is anti-American. The critics want Gwinnett, the state's largest school district, to return to the prior AP U.S. history framework and exam. The criticism in Gwinnett is part of a national debate that's emerged in recent months about the course, led by conservatives, after some changes were made to the coursework in 2014.
