Roth and Lee are concerned with the learning community as a theoretical and analytical category; they critique how some educators use the notion to design learning environments without considering the fundamental structures implied in the category. Their analysis does not consider the appearance of learning communities in the United States in the early 1980s. For example, the Evergreen State College, which is widely considered a pioneer in this area, established an intercollegiate learning community in 1984. In 1985, this same college established the Washington Center for Improving the Quality of Undergraduate Education, which focuses on collaborative education approaches, including learning communities as one of its centrepieces.
