This paper examines the growth and characteristics of online learning in comparison to traditional campus-based and blended educational models. Drawing on enrollment data and retention research, the paper explores the advantages of online learning — particularly its accessibility for non-traditional students and cost benefits for institutions — alongside its disadvantages, including higher attrition rates and concerns about academic integrity. The paper references empirical studies to contextualize dropout differentials between online and campus students, considers the role of socioeconomic factors, and concludes with a forward-looking assessment of how online and hybrid learning formats are likely to evolve in higher education.
The paper effectively uses comparative analysis supported by empirical citations. Rather than relying on a single source, it triangulates findings across several studies (Diaz, 2000; Murray, 2001; Bauman, 2002) to build a nuanced picture of attrition trends. This technique — acknowledging variation between studies while still identifying a consistent pattern — demonstrates strong critical engagement with secondary research and avoids overgeneralizing from any single data point.
The paper opens with a definitional section establishing what counts as online, blended, and traditional learning. It then moves through a thematic sequence: enrollment growth, attrition statistics, accessibility benefits, cost implications, academic integrity risks, and a future outlook. This logical progression from definition to evidence to implications is a classic academic essay structure well suited to comparative topics at the undergraduate level.
The development and growth of online learning has created opportunities for both students and academic institutions alike. The online learning environment may be argued as offering many benefits, such as increasing accessibility to education and supporting diversity, as well as providing potentially lucrative revenue streams for institutions. These benefits have driven its growth, but they are not without drawbacks — online courses consistently report higher attrition rates than their campus-based equivalents. The aim of this paper is to examine online learning, discussing the advantages and disadvantages of the online environment in comparison to campus-based learning and the blended learning environment.
An online course has been defined as one where a minimum of 80% of the content is delivered through the online environment (Allen & Seaman, 2014). Online delivery may include a range of different mediums, including — but not necessarily limited to — live or recorded video streaming, podcasts, online discussion groups, text-based lectures, and online text-based content. The key to the definition is the availability of content, which is usually accessible through an Internet connection.
A ground-based or face-to-face instruction model is more traditional, with the majority — if not all — of the teaching delivered in a classroom setting. This is defined as a course where 29% or less of the content is delivered online (Allen & Seaman, 2014). Courses where between 30% and 79% of the content is delivered online represent a hybrid of the traditional and online learning environments, and are defined as a blended or alternative course model (Allen & Seaman, 2014).
The online learning environment has been growing at a phenomenal rate. It was estimated that in 2013 there were 7.1 million students taking one or more online courses in the United States (Allen & Seaman, 2014). Given that statistics indicate there are approximately 14.4 million undergraduate students and 2 million graduate students in the United States (Statistics Brain, 2014), online learners represent a significant proportion of the total student population. It is a testament to this growth that institutions such as the University of Phoenix and American Public University have established themselves as respected academic institutions. Nevertheless, although there may be growing respect for online learning and online degrees, some reserved opinions persist, with a continuing belief among some that online learning may be inferior to ground-based or campus learning. This view appears to be waning: in 2003, 42.8% of chief academic officers believed that online learning was inferior, a figure that had fallen to 26% by 2013 (Allen & Seaman, 2014). These changing statistics may reflect increased familiarity and acceptance of online courses, as well as the potential for improved content quality and student support as more resources are directed toward online education.
A specific challenge faced by many online courses is that of retention (Heyman, 2010). Assessing overall retention statistics or attrition levels to compare online learning with campus-based learning is very difficult due to the wide variety of measures that may be used. Nevertheless, the general consensus is that online students display higher attrition levels when compared to equivalent traditional campus students (Heyman, 2010). Research by Bauman (2002) assessed attrition levels for online learning courses and found that it was not unusual for these to exceed 50%.
Diaz (2000) undertook a study providing a more direct level of comparison, examining the dropout rates of online students and traditional students on equivalent courses. The results supported the presence of a differential between online and campus students, though the level of attrition was considerably lower than Bauman's figures suggested: online attrition stood at 13.5%, compared to 7.2% for traditional campus students (Diaz, 2000). When measuring attrition or retention, there are many influences beyond the course itself, including the level of student preparedness, overall commitment, and academic ability — all of which affect the likelihood of dropping out (Heyman, 2010).
Different educational institutions have different entry requirements and student profiles, which may account for some of this differential. This is illustrated by research conducted by Murray (2001) at the online educational program at Washington State Community College. The overall retention rate for traditional students undertaking classroom-based lessons was 85%, while this fell to 70% for online students (Murray, 2001).
