At Stanford, we recently placed three computer science courses online, using a similar format. Remarkably, in the first four weeks, 300,000 students registered for these courses, with millions of video views and hundreds of thousands of submitted assignments.
What can we learn from these successes? First, we see that video content is engaging to students — many of whom grew up on YouTube — and easy for instructors to produce.
Second, presenting content in short, bite-size chunks, rather than monolithic hourlong lectures, is better suited to students’ attention spans, and provides the flexibility to tailor instruction to individual students. Those with less preparation can dwell longer on background material without feeling uncomfortable about how they might be perceived by classmates or the instructor.
Conversely, students with an aptitude for the topic can move ahead rapidly, avoiding boredom and disengagement. In short, everyone has access to a personalized experience that resembles individual tutoring.
Watching passively is not enough. Engagement through exercises and assessments is a critical component of learning. These exercises are designed not just to evaluate the student’s learning, but also, more important, to enhance understanding by prompting recall and placing ideas in context.
Moreover, testing allows students to move ahead when they master a concept, rather than when they have spent a stipulated amount of time staring at the teacher who is explaining it.
For many types of questions, we now have methods to automatically assess students’ work, allowing them to practice while receiving instant feedback about their performance. With some effort in technology development, our ability to check answers for many types of questions will get closer and closer to that of human graders.
Okanagan Mission Secondary School in Kelowna, B.C., is among the early Canadian adopters of the flipped classroom - a model where students switch around what's traditionally covered at school and what's assigned for kids to do at home. Instead of lectures in class and homework after school, these students are watching lectures at home care of the Web and working one-on-one on assignments with teachers during school hours. The Globe talked to some of the students - kids taking senior math and biology classes - and their teacher to find how what they make of "flipping out."
