What major educational reform movement took place in the 1980s?

The major educational reform movement that took place in the 1980s is reflected in the "Nation at Risk" report. Released in 1983 by the National Commission on Excellence in Education, this report was a pivotal document highlighting significant concerns about the quality of education in the United States. It emphasized the need for reform to improve academic standards, increase rigor, and address the growing competition from other countries. This movement led to various initiatives aimed at educational improvement, including higher standards for teachers, increased accountability, and curriculum reform, which had a lasting impact on the educational landscape in the following decades.

In contrast, other options like "Discovery Learning" and "Open Classrooms" refer to specific instructional strategies or educational environments rather than broader reform movements. The "Every Child Succeeds Act," while significant, was enacted much later in 2015, making it unrelated to the educational reforms of the 1980s. Therefore, "Nation at Risk" stands out as the pivotal movement from that era, shaping discussions around educational policies and practices.
