Lesson 11. Changing education


Technology has impacted almost every aspect of life today, and education is no exception. Or is it? In some ways, education seems much the same as it has been for many years. A 14th century illustration by Laurentius de Voltolina depicts a university lecture in medieval Italy. The scene is easily recognizable because of its parallels to the modern day. The teacher lectures from a podium at the front of the room while the students sit in rows and listen. Some of the students have books open in front of them and appear to be following along. A few look bored. Some are talking to their neighbors. One appears to be sleeping. Classrooms today do not look much different, though you might find modern students looking at their laptops, tablets, or smart phones instead of books (though probably open to Facebook). A cynic would say that technology has done nothing to change education.
However, in many ways, technology has profoundly changed education. For one, technology has greatly expanded access to education. In medieval times, books were rare and only an elite few had access to educational opportunities. Individuals had to travel to centers of learning to get an education. Today, massive amounts of information (books, audio, images, videos) are available at one’s fingertips through the Internet, and opportunities for formal learning are available online worldwide through the Khan Academy, MOOCs, podcasts, traditional online degree programs, and more. Access to learning opportunities today is unprecedented in scope thanks to technology.
Opportunities for communication and collaboration have also been expanded by technology. Traditionally, classrooms have been relatively isolated, and collaboration has been limited to other students in the same classroom or building. Today, technology enables forms of communication and collaboration undreamt of in the past. Students in a classroom in the rural place for example, can learn about the Arctic by following the expedition of a team of scientists in the region, read scientists’ blog posting, view photos, e-mail questions to the scientists, and even talk live with the scientists via a videoconference. Students can share what they are learning with students in other classrooms in other states who are tracking the same expedition. Students can collaborate on group projects using technology-based tools such as wikis and Google docs. The walls of the classrooms are no longer a barrier as technology enables new ways of learning, communicating, and working collaboratively.
Technology has also begun to change the roles of teachers and learners. In the traditional classroom, such as what we see depicted in de Voltolina’s illustration, the teacher is the primary source of information, and the learners passively receive it. This model of the teacher as the “sage on the stage” has been in education for a long time, and it is still very much in evidence today. However, because of the access to information and educational opportunity that technology has enabled, in many classrooms today we see the teacher’s role shifting to the “guide on the side” as students take more responsibility for their own learning using technology to gather relevant information. Schools and universities across the country are beginning to redesign learning spaces to enable this new model of education, foster more interaction and small group work, and use technology as an enabler.
Technology is a powerful tool that can support and transform education in many ways, from making it easier for teachers to create instructional materials to enabling new ways for people to learn and work together. With the worldwide reach of the Internet and the ubiquity of smart devices that can connect to it, a new age of anytime anywhere education is dawning. It will be up to instructional designers and educational technologies to make the most of the opportunities provided by technology to change education so that effective and efficient education is available to everyone everywhere.

Lesson 11. Paper books vs Digital books

The race is getting tighter now. With downloadable music already set to completely replace CDs, the next round of the format battle begins. Who will come out on top: ebooks or printed books?
There are many factors to consider when discussing the matter of ebooks vs. printed books, but ultimately, it boils down to the reader’s preference. Avid fans of printed books claim that there’s still nothing like the smell of paper and the rustle of the pages as the reader flips gently through the book with their fingers. There’s something intimately rustic about the entire experience, they claim, and it’s one that cannot be derived from the cold, electronic ebook version.
On the other hand, those who prefer the ebook often say that the device takes a whole lot of weight from their shoulders – literally. Packing for trips is bad enough as it is, but it becomes doubly so when confronted with the task of choosing which book to bring. With the ebook, however, a reader can take hundreds of books with them on the journey, and only take up a few square inches in their carry-on bag.
Apart from these physical considerations, however, studies have shown that when it comes to reading comprehension, printed books are still a better choice. One such study was recently conducted by the Joan Ganz Cooney Center at Sesame Workshop. The study found that literacy building in children is more effective with a printed book than with an ebook because of the centralized focus on the story and the opportunities for interaction between the child and the parent reading the book with the child. While ebooks also deliver the story, and encourage children to participate with interactive add-ons, there is no conversation and nothing to encourage the child to verbalize or explore using language. In fact, the research concluded that sometimes “click-through” added features can actually detract from the reading experience because of all the interruptions.
Of course, for other people – especially adults, who are more able to comprehend the overall story or meaning in the text – these interactive features such as linking, bookmarking, highlighting, and others provide a huge benefit and meet many of their needs. By and large, however, some devices tend to overdo it, and so end up creating more distractions than necessary.
There’s also the matter of production cost. Obviously, printed books cost more because of the resources needed. Ebook reader manufacturers, though, spend the bulk of their production cost on the device itself, and from then on everything is digital and a fraction of the cost per book, compared to printed books.
Marc Slater weighs in on the debate. “Clearly, the winner in this round is none other than the person doing the reading, no matter which method they choose. With all of the options available in the market, there simply is no way to not enjoy reading. If anything, what people should be focused on is learning how to read faster. After all, there are so many books to pick up and read out there – both in printed form or ebook version – that we should be concentrating on reading as many as we can, in whatever format suits us best.”
