Readers of my blog will know that I believe quality instruction makes a tangible difference in learning, and that well-educated and well-prepared teachers are essential. I have been thinking quite a bit about on-line learning, something that occupies much of my time.
In the 1960s, around the time I was preparing as a teacher, John Carroll, an educational psychologist, proposed that the amount of time learners spend on learning a task, relative to the time required, is a critical factor in determining their success in learning.[1] One of the constraints of face-to-face schooling is that it imposes constraints on the amount of time learners have to achieve mastery.
The advantage of online education aligns with Carroll's emphasis on learning time and individual differences in learning needs. In Carroll's model, the aptitude of a student, including their prior knowledge and learning abilities, significantly influences how they learn. Online learning facilitates this by allowing learners to tailor their learning to their individual aptitudes. For example, a student who finds calculus challenging can allocate more time to this subject, revisiting complex problems through videos and online forums until they grasp the concepts.
Online learning provides learners with the flexibility to access educational resources at any time. Someone interested in history, for example, can spend more time investigating a topic of interest.
Online learning requires perseverance. Self-motivated students can spend additional time mastering subjects of interest or difficulty. This is evident when a learner studying programming online spends extra hours developing an application. That learner is achieving mastery and exhibiting the willingness to invest time in learning.
Quality of instruction is also a critical factor. Online learning offers access to varied instructional methods, materials, and instructional models (teachers). A learner who prefers demonstrations might explore YouTube while one who prefers print can look for articles and e-books.
Carroll's model points to the importance of student understanding. Learners who find one video difficult to comprehend can look for another that is clearer or better aligned with the learner’s prior understanding. Self-discipline and motivation are two critical characteristics of successful online learners. The learner's willingness to engage with the material is crucial. Online learning offers flexibility and some level of individuation, but it demands a high level of self-regulation from students.
Internet-based learning offers a flexible, somewhat individualized educational experience that can align with the needs, aptitudes, and time that different learners need to achieve mastery. However, it also requires enormous self-discipline and motivation.
