The Chronicle of Higher Ed's Report on Apple's Big Announcement

Apple's New E-Textbook Platform Enters an Already Crowded Field

Apple made a splashy entrance into the digital-textbook market on Thursday at an event here at the Guggenheim Museum, but its new build-your-own-textbook tool is likely to lead to more fragmentation in the market rather than becoming a dominant new model.

During an hourlong presentation, officials from the tech company known for shaking up music and other industries used sweeping language to describe the changes they believed their new products would bring. The company is "reinventing the textbook," said Philip Schiller, a senior vice president, and "as students are introduced to iPad, remarkable things are happening." Apple's leaders identified high schools as the biggest initial market for its new books, though they mentioned potential in higher education as well.

The most unusual offering was iBooks Author, a free book-making program that lets anyone build a rich-media textbook that can be displayed easily on an iPad. Professors can drag in images from their iPhoto libraries, video clips from iTunes, and lecture slides from Apple's Keynote program (a competitor to Microsoft's PowerPoint).

A key drawback, however, is how much the new program relies on professors and students adopting Apple products. The book-building program runs only on Macs, not on PC's, and the resulting textbooks work only on iPads, not on competing Android tablets.

When Apple first released its iTunes software and music store in 2001, it set new standards for digital music that led to the slide of CD's in favor of 99-cent-per-song downloads. There was nothing else like the iTunes music store at the time, and the company was able to cajole music publishers into accepting lower prices than they wanted to ride the digital-music wave.

When it comes to e-textbooks, though, Apple is hardly the first mover, and it does not seem to have the muscle with book publishers that it flexed with music executives. A handful of textbook publishers participated in the Apple announcement—mainly McGraw-Hill, Pearson, and Houghton Mifflin Harcourt. But those publishers have formatted only a handful of titles for Apple's new iBooks2 app, and they have not pledged a low price beyond those initial titles (which are $14.99 each or less).

Genevieve Shore, CIO and director of digital strategy for Pearson, said in an interview at the event that Apple's platform was just one of many the publisher was using to distribute its e-textbooks. "We kind of call it 'flat content.' It will go to whatever channel students tell us to go to," she said. "What Apple brings to it is it's beautiful," she said, referring to the slick look of the book-building tool and the resulting iPad books. (Apple staff members at the event refused to answer reporters' questions.)

Does she worry that professors could use the new free book-making software to put publishers out of business? Not at all, she insisted. In fact, she pointed out that Pearson has offered a custom-textbook service in print for 30 years, and also offers a digital build-your-own textbook system. Other major publishers already offer similar services as well.

In that way, Apple has simply thrown another platform into a crowded and incompatible market. That diversity seems to have helped slow adoption of e-textbooks, because students and professors have to learn new interfaces for each publisher's offering.

A separate product announced at the event may end up being more widely adopted than the textbook software. Apple announced the first major upgrade to its iTunesU service since it opened four years ago. The changes make it easier for professors to use the company's free multimedia service as an alternative to a course-management system, grouping syllabi, lecture videos and podcasts, and textbooks in the same virtual folders that can be loaded in iTunes or on an iPad.

Metacognition and Student Learning

This evening, my family will sit down on the couch together to enjoy the opening episode of America's favorite spectacle of poor metacognition. Along with millions of others, including some of you, we will marvel at the sight of so many human beings eager to put their deficient cognitive skills on display for the world.

I'm talking, of course, about the season premiere of American Idol, where lousy metacognition will join lousy singing for two cringeworthy hours tonight and another hour tomorrow night, as amateur musicians audition for the opportunity to win fame, fortune, and a recording contract. The opening two episodes of each season have become notorious for featuring the worst singers who auditioned for the show, encouraging viewers to engage in some gentle schadenfreude as Idol participants make fools of themselves on national television.

What makes so many of those atrocious singers laughable to us—excepting the ones who put on deliberately bad performances in order to get on camera—turns out to be a problem that plagues many undergraduates, especially the weakest among them: an inability to judge accurately their own level of skill or knowledge in a specific area.

Poor metacognition means that some terrible yet hopeful singers on American Idol are unable to assess their own weak vocal talents. And it means that some students have a mistaken sense of confidence in the depth of their learning.

Cognitive psychologists use the term metacognition to describe our ability to assess our own skills, knowledge, or learning. That ability affects how well and how long students study—which, of course, affects how much and how deeply they learn. Students with poor metacognition skills will often shorten their study time prematurely, thinking that they have mastered course material that they barely know.

I was introduced to this concept by Stephen Chew, professor and chair of the psychology department at Samford University, who wrote to me in response to my column last month on teaching and human memory. Chew's credentials in this area immediately caught my attention: In 2011 he was named one of four outstanding professors of the year by the Council for Advancement and Support of Education and the Carnegie Foundation for the Advancement of Teaching. His work focuses specifically on the implications of cognitive research for learning and instruction.

As a part of his work in this area, Chew has produced a series of videos for students on how to study effectively. After watching all five of the videos in his series—which I highly recommend to all administrators and faculty members who work with first-year students—I thought it worthwhile to devote one more column to drawing out a principle from cognitive psychology that could help many of us do our jobs better.

I asked Chew to give readers a basic definition of metacognition, with some illustrations of the concept both from education and everyday life. "Metacognition," he explained in an e-mail, "is a person's awareness of his or her own level of knowledge and thought processes. In education, it has to do with students' awareness of their actual level of understanding of a topic. Weaker students typically have poor metacognition; they are grossly overconfident in their level of understanding. They think they have a good understanding when they really have a shallow, fragmented understanding that is composed of both accurate information and misconceptions."

That leads weak students, he said, to make poor study decisions: "Once students feel they have mastered material, they will stop studying, usually before they have the depth and breadth of understanding they need to do well. On exams, they will often believe their answers are absolutely correct, only to be shocked when they make a bad grade."

As for examples outside of education, Chew had no trouble pointing them out in a variety of areas, including reality television shows.

"Poor metacognition is a big part of incompetence," he explained. "People who are incompetent typically do not realize how incompetent they are. People who aren't funny at all think they are hilarious. People who are bad drivers think they are especially good. You don't want to fly on a plane with a pilot who has poor metacognition. A lot of reality shows like American Idol highlight people with poor metacognition for entertainment. Everyone knows people who are seldom in doubt but often wrong."

Yes, I know quite a few of those people. I'm related to at least one of them.

But let's assume that I want to help people with poor metacognitive skills, instead of just trying to avoid them at our next holiday gathering. I asked Chew what faculty members can do to assist students do a better job of assessing their own skills and knowledge.

"The best way to reduce the impact of poor metacognition," Chew said, "is to use formative assessment during teaching. Formative assessments are brief, low-stakes activities that students do in order to give both themselves and the teacher feedback about their level of understanding. There is a wide assortment of assessments that faculty can use, such as think-pair-share activities, minute papers, and so-called 'clicker' questions."

"I like to use ConcepTests, developed by Eric Mazur, in which I present the class with a multiple-choice question similar to ones that will be on the exam," he added. "Students select their answers individually, and I poll the class. They can then discuss their answer with other students, after which I poll the class again. Finally, we discuss the answers as a class. This gives me a sense of how well students understand the material. I can identify and address problem areas."

Most important, he said, these ConcepTests—which can be used quite simply even in the most overcrowded lecture courses—help give students a more accurate assessment of their own understanding.

"I emphasize," Chew said, "that the question I use is similar in difficulty level to questions they will see on exams, so if they did not answer correctly or were confused, they need to improve their understanding. Formative assessment helps students study and learn more effectively beforeexams, and they are less likely to feel 'tricked' by questions they didn't expect. The actual exam should never be the first time the faculty or the students get feedback about the actual level of student understanding."

Chew's recommendation for the frequent use of "brief, low-stakes" assessments echoes a key pedagogical principle that came out of last month's column—and that corresponds with what just about every expert in learning theory and pedagogy will tell you. An understanding of metacognition, and the influence it has on our students, gives us one more reason to shift our courses away from providing students with a steady diet of lectures, punctuated by a few high-stakes exams.

Lectures do have a place in the college classroom of course. Just about every teaching strategy we can imagine may have its place over the course of the semester. But I know from my own experience—as I am gearing up to teach a literature survey course in the spring—how easily we can allow lectures to become the sole or dominant mode of instruction, especially as the semester wears on, and we feel the urge to cram as much material into the course as possible.

A 40-minute lecture, followed by a 10-minute formative-assessment activity, may help our students learn much more effectively than a 40-minute lecture followed by weak discussion starters like "Any questions?" And, as Chew pointed out in response to an early draft of this essay, students frequently don't ask questions precisely because their poor metacognitive skills have convinced them that they understood the lecture perfectly.

Incidentally, formative-assessment activities can be even simpler than the one Chew describes. The most basic activity a faculty member can use to check understanding at the end of a class is the now-classic "minute paper," described in Thomas K. Angelo and K. Patricia Cross' Classroom Assessment Techniques. At the end of a lecture or discussion, ask students to pull out a half-sheet of paper and answer some variation on the following two questions: "What was the most important concept you learned in class today?" and "What concept did you find the most difficult or confusing?"

When students identify a throwaway example you used as the most important concept they learned, you know you have more work to do. And when you point that out to students in the next class session, they should know that they have more work to do as well.

For readers interested in learning more about metacognition, and its influence on what we experience in our classrooms, begin by checking out the first episode in Chew's video series. In addition to his clear explanation of the topic, he provides an interesting example from one of his own courses, in which he graphs out the test scores his students expected to receive and the scores they actually received.

Chew also supplied me with a list of additional reading materials in this area.

Chronicle of Higher Education report

On Wednesday thousands of scholars joined millions of people around the world in online protest of two proposed laws, the Stop Online Piracy Act (SOPA) and the Protect IP Act (PIPA). SOPA and PIPA would, in the view of many observers, authorize wide-ranging online censorship in the guise of stopping copyright infringement. So far, the protest appears to have been a success: Congressional support for the proposed laws is crumbling.

On that same day, the U.S. Supreme Court issued an opinion in a copyright case that may be just as important as SOPA and PIPA—and potentially just as harmful to the interests of scholars, librarians, and archivists. In Golan v. Holder, a group of conductors, educators, film distributors, and others challenged the constitutionality of Congress's decision in 1994 to remove millions of books, films, songs, and other creative works, mostly foreign, from the public domain and "restore" their copyrights. It did so to conform to an international agreement, although it is far from clear that the move was required to put the United States in conformity. Some of the works taken from the public domain and put back under copyright are very famous; they include Prokofiev's "Peter and the Wolf," the symphonies of Shostakovich, Picasso's "Guernica," and the English films of Alfred Hitchcock.

Lingustic perspective on grammar

From "Analyzing English Grammar" by Thomas P. Klammer, Muriel R. Schulz and Angela Della Volpe.

As a speaker of English, whether as your first language or as a language you have learned or are still learning later in life, you already know much of the grammar that we present in this book. However, there are different ways of knowing. Our goal is to change your way of knowing grammar.

When you are able to list the steps to be followed in order to produce a result, you are said to have focal knowledge of a process. When your information about how to produce a result is at an unconscious level, it is said to be tacit knowledge.

The word for the subject of our study, grammar, has a number of distinct meanings. Grammar can refer to the linguistic system that presumably exists in the mind of a speaker of a language, the knowledge to which we refer description of the language system. Furthermore, grammar can refer to an ideal set of rules.
