Growing pressure to provide more virtual instruction is spurring efforts to design large courses that balance standardization of content with flexibility for instructors. Each course uses a common template, which sets out lesson objectives, lecture material, practice activities, and assessments. The process results in a single version of each course, which assures a college that its curriculum is up to date and well integrated with other courses. Colleges in the for-profit sector use a similar model for revising and creating courses, although the notion of scale can have a different meaning. Kaplan University, for example, tries to view scale in educational terms. A course title with multiple sections and multiple instructors typically enrolls 1,000 to 2,000 students at a time. The high volume of students in the same course allows Kaplan to assign about 100 students to demographic subgroups, such as race, ethnicity, level of parents' education, or prior academic success, and then study the data to spot any differences that may emerge.
