According to the passage, what is applied in teaching today?

Digital rap3 players like Apple’s iPod can download and play hours of music and thousands of images. It’s not surprising that they are among the nation’s most popular entertainment devices. Now, a handful of U. S. colleges and universities are using them as education devices.
     That chance to listen as many times as necessary makes a difference. Back in the days when students came to class, they hear what the teacher says. They rely on the notes that they take away from it and they type it. With the lectures on iPods and on-line discussion forums when requested by students, pupils grasp the material more quickly.
     And there may be additional benefits for shy students. They actually begin to shine in an on-line environment. in the online world, they’re able to create thoughts, write them down, and post them to class where they can be a full participant.
     According to some expert, this technology is d0ing more than giving students the flexibility to listen and learn anytime, anywhere; instead it’s empowering them as education consumers, and colleges and universities are paying attention. Nowadays, they need to focus on the student experience and make the entire teaching experience not about the professor giving their lectures. It’s about how can schools reach out to the students in a way that meets their needs, since so many of today’s students are not "traditional learners" any more.
