Flipping the classroom – the practice of giving students access to lectures before they come to class and using class time for more engaging activities – has not been nearly as divisive as many other trends in educational technology, such as massive open online courses or outsourcing digital services. A comparison between the flipped classrooms and their traditional counterparts found no demonstrable difference in student outcomes. Criticism of the flipped classroom model is usually derived from arguments between the didactic and progressive camps in education. Members of the didactic camp oppose flipping the classroom to preserve the role of the teacher, while the progressive camp instead advocates a move toward projectbased learning and inquiry. There’s also the knee-jerk reaction to something new. Students in flipped classrooms can no longer expect to sit through a lecture and complete work on their own time. When coupled with challenging course materials and a shaky internet connection, the change has led many to voice their frustration on social media. The same goes for professors, who can no longer expect to give 90-minute presentations. The extra work that goes into recording videos and planning classroom sessions leads many teachers to report an exhausting first year of flipping the classroom. As a matter of fact, good ideas in education are incredibly fragile. I am, therefore, not so optimistic that people are going to be on their mettle. Some critics, like Ian Bogost, a professor at the Georgia Institute of Technology who placed himself in the “cautiously cautious” camp on flipped classrooms, said the model is only one of many factors in the larger debate about technology-based educational reform. The matter, in fact, is not the flipped classroom specifically; it is the evolving anxiety involved with the operation and ownership of institutions. Change is a process that tends to solidify quickly. If a school were to make this, by the third year it could be set in stone. Additionally, one of the most important concepts in teaching is creating opportunities to make thinking visible. When teachers can really see the thinking of their students, they can provide these students with the support and encouragement they need to be successful. It is believed that by using the thoughtful approach to the flipped learning method, teachers have an amazing opportunity to gain insights into where students are struggling. 28.
