Choices, Changes, and Challenges: Curriculum and Instruction in the NCLB Era
This report examines time spent during the school week on core academic subjects and how that's changed since NCLB was enacted in the 2001-2002 school year. It finds that approximately 62 percent of school districts increased the amount of time spent in elementary schools on English/language arts and or math, while 44 percent of districts cut time on science, social studies, art and music, physical education, lunch or recess.
