Massively online open courses have transformed learning. Thanks to MOOCs, pretty much anyone with an internet connection and a desire to learn can receive a vital education on almost any topic.

Of course, these online courses aren’t free. But Udemy is holding a Holiday Flash Sale that’ll get you pretty close. From now through Friday, December 29, 2017, Cult of Mac readers can access any course costing $200 or more for just $10.

During its education event in January, Apple unveiled its plans to revolutionize the K-12 classroom with the iPad, electronic textbooks, a revamped version of iTunes U that supports content for K-12 schools as well as higher education, and tools for educators to create their own digital content using iBooks Author and iTunes U.

In the intervening months, schools and districts around the country have made significant investments in iPads, including the San Diego Unified School District, which invested $15 million in 26,000 iPads for its students. Those sales created a record quarter for Apple in the K-12 education market.

With the back to school season upon us, it’s clear that the massive iPad deployments will give Apple the opportunity to disrupt the classroom in the ways it has whole industries and, in many ways, that’s a good thing.

Both the Atlantic and NY Times ran stories this week focusing on Coursera, an initiative involving several high-profile universities that are putting a range of classes online for anyone who wants to take them. The initiative is part of trend in higher education to make learning available to anyone who has the personal or professional interest in taking a college or university class regardless of financial or geographical challenges.

While Coursera is getting a lot of media attention and is racking up hundreds of thousands of students around the globe, the idea of free college learning is hardly new. Apple introduced the concept of watching or listening to college lectures when it first rolled out iTunes U in 2007. More recently, Apple revamped iTunes U to offer a much more immersive experience that includes assigned readings, activities and projects, and even note-taking in addition to recorded lectures.

With its e-textbook initiative, iTunes U, and a range of educational resources, Apple is pitching the iPad as critical element in 21st century schools. Many schools have already begun iPad tests or full-scale deployments. In other schools, however, there’s still a fight over where and how the iPad and other technologies fit into the classroom. A battle erupted between teachers and lawmakers in Idaho earlier this year over new technology requirements in the state’s schools.

So what makes some schools embrace iPads and other new technologies while others resist them? It turns out that the answer may lie in the personal technology preferences of school and district administrators.
