However, fewer studies have examined class size in online higher education courses.<\/p>\n<p>Enrollment in online courses and programs has consistently increased for more than a decade, and some leaders in higher education project that online education may become even more prevalent as instructors and students continue to navigate life amid the COVID-19 pandemic.<\/p>\n<p>The authors of the Oregon State study \u2014 Rebecca Arlene Thomas, Ph.D., a postdoctoral scholar with the Ecampus Research Unit, and director Mary Ellen Dello Stritto, Ph.D. \u2014 pursued this topic to help advance the quality standards of online higher education.<\/p>\n<p>\u201cInvestigating class sizes at the university level is important because administrators can use these results to make recommendations about setting limits on class sizes,\u201d Dello Stritto said. \u201cWhile capping at 30 may be beneficial for upper-division and STEM courses, in other types of lower-division or liberal arts courses, larger class sizes may not be problematic.<\/p>\n<p>\u201cThe results suggest we should leverage the benefits of smaller class sizes for courses where students could benefit the most.\u201d<\/p>\n<p>Oregon State\u2019s study found, in part, that:<\/p>\n<ul>\n<li>Final grades in online STEM and upper-division courses were higher in classes with fewer than 30 students compared to classes with 30 or more students.<\/li>\n<\/ul>\n<ul>\n<li>There is no relationship between class size and D or F course grades, or course withdrawals in STEM and upper-division online courses.<\/li>\n<\/ul>\n<ul>\n<li>30 students may be the tipping point where the benefits of \u201csmall\u201d online courses may wear off. \u00a0The authors suggest that instructors may change course aspects such as their pedagogy, learning outcomes or communication once courses exceed the 30-student threshold.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/journals3.oregondigital.org\/nwelearn\/article\/view\/5608\/7333\" target=\"_blank\" rel=\"noopener\">Read the publication<\/a> \u2014 titled \u201cStudent Outcomes in Online Courses: When Does Class Size Matter?\u201d\u00a0\u2014\u00a0and learn more about how the <a href=\"https:\/\/nam04.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fecampus.oregonstate.edu%2Fresearch%2F&amp;data=04%7C01%7Cchristina.dearment%40oregonstate.edu%7Cd502257e0dc94dbe3bff08d9673412c9%7Cce6d05e13c5e4d6287a84c4a2713c113%7C0%7C0%7C637654295616445897%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&amp;sdata=FXwKPyRMlMpmskbfhUcOt%2FLW2CaBsWCSLIwuqR07JO0%3D&amp;reserved=0\">Ecampus Research Unit<\/a> contributes to effective online teaching, learning and program administration.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\"><\/span> <span class=\"rt-time\"> 2<\/span> <span class=\"rt-label rt-postfix\">minute read<\/span><\/span>The Oregon State Ecampus Research Unit recently conducted a study on a rarely researched topic in online education: class size.
