These higher-level cognitive abilities are localized to the frontal and prefrontal cortex in the brain. “Overwhelmingly, children who are bilingual from early on have precocious development of executive function,” Dr. Bialystok said.

Dr. Kuhl calls bilingual babies “more cognitively flexible” than monolingual infants.

“This special mapping that babies seem to do with language happens in a social setting,” Dr. Kuhl said. “They need to be face to face, interacting with other people. The brain is turned on in a unique way.”

“Human brains are wired to learn best in social interactions, whether that learning is about language or problem-solving or emotion,” Ms. Lebedeva said, “but language is such a ubiquitous human behavior that studying it gives us an example of how more general learning takes place.”

at the science-oriented Ultimate Block Party held in New York City this month, children of different backgrounds played games in which they were required to sort toys either by shape or color, based on a rule indicated by changing flashcards. A child sorting blue and yellow ducks and trucks by shape, say, might suddenly have to switch to sorting them by color. The field games exemplified research findings that bilingual children have greater cognitive flexibility than monolingual children. That is, they can adapt better than monolingual children to changes in rules—What criteria do I use to sort?—and close out mental distractions—It doesn’t matter that some blue items are ducks and some are trucks.

This issue is so prevalent that some experts recommend we teach students “academic language.”

This additional distance between the writer and reader decreases the likelihood that the journals will actually be read. And if the journals are not read by teachers, the research will be slow to influence educational practice, if it does at all.

We are spending time, effort, and sometimes money on research doomed to remain idle because it’s not communicated well. The poor writing prevents worthwhile application.

If understanding depends on translating the language, students who struggle with this prerequisite may lack the motivation or inertia to think beyond, or even through, the interpretation. We’re making understanding more difficult—a seeming antithesis to our role as educators.

Why can’t “academic” journals and textbooks utilize common principles of good writing. Why do we insist on communication complexity when our goals would be better served by simple clarity?

Status? Are we insisting on “academic writing” because it separates journals from the “rags” intended for the masses or textbooks from the unlearned? If so, our goal must be to maintain some perceived elite readership—a readership probably not teaching or sitting in our classrooms.

Do we think that our research and subject matter is complicated, therefore our communicating should also be complex? This is so contrary to logic and sound teaching that it’s an oxymoron.

A complex topic requires simple writing, especially when the reader likely lacks the author’s background knowledge and experience. This is almost always the case when a researcher seeks to address individuals who were not part of the research team or involved in similar research themselves, or when experts in a field seek to articulate concepts for students.

Medina presents ideas simply and in ways known to foster learning. As the brain engages in elaboration, it overlays new data with known experiences, making connections that help construct understanding. Medina relates a new, complex topic to a familiar childhood activity—origami (even though he is not writing for children). By giving us a reference point for understanding DNA, he equips us with the tools needed to construct understanding. Isn’t this what we should be striving for, both in our textbooks and our journals?

I've seen that the introduction of new technology can provide a reason to rethink a course from the ground up and reassess its core educational goals. Often the greatest educational benefits seem to come from this process, not just the technology that encouraged it.

It might be safe to say that each time a new medium appears, no matter how different it is from the last, the normal reaction of first adopters is to use it as a new package for existing content.

I've seen that the introduction of new technology can provide a reason to rethink a course from the ground up and reassess its core educational goals.

It can be easy to forget that we human beings are more than brains connected to an apparatus that moves us around in space. Instead, we belong to communities, we live in neighborhoods, we have local culture and events. Inquiry into these real things led to many of the fields we now call science, literature, mathematics, and history. Why then do we isolate instruction in those fields to a classroom, instead of deriving instruction from the environment from which these subjects originated?

place-based learning.2 One such example, Dow Day, is a mobile documentary that relives the student protests of 1967 in Madison, Wisconsin, against the Dow Chemical Company. In this activity, location-aware handheld devices add an augmented layer of history to a walk through the campus, placing the student in the role of a news reporter. By monitoring the device's GPS, Dow Day creates the illusion of additional characters standing in physical space and facilitates simulated conversations with these historical entities. In addition, when players walk to predefined media locations, they trigger video footage showing the physical scene from 40 years ago, effectively superimposing the marchers and police onto the current landscape (see Figure 2).

Situated theories of cognition claim that knowing and doing are inherently linked.4

One such example is a mobile game called Mentira, produced at the University of New Mexico. The game is designed to teach an introductory college Spanish course in ways that are contextually sound for language learning. In the first unit, students play a mystery game on handheld devices in class, taking on a role and a goal within a story told completely in Spanish. In the second part, the class moves outside to a local Spanish-speaking neighborhood where they continue the story while interacting with physical and virtual Spanish speakers in real places (see Figure 3).

With Mentira, students learn Spanish outside the classroom through narrative and interaction with members of a Spanish-speaking neighborhood, re-situating language in practice.

Identifying the disconnect, a small team from the Animal Science and the Academic Technology departments at UW–Madison are working on a prototype for hobbyist birdwatchers. WeBIRD aims to crowdsource ornithology research by providing a tool for hobbyist practitioners. A birder will record the audio of a bird heard out in the field and have the system identify the species while logging the sighting's location, current weather, time of day, and date to a central database. This data can then be used for anything from formal research of migration patterns over time to individual questions such as, "Where am I most likely to see a cardinal this time of year?" The potential for location-aware, casual gaming structures such as birder achievement badges and leader boards are also being investigated in order to provide additional social play motives for participation.

Learning happens anywhere someone has questions and the means to explore answers. As ubiquitous access to information continues to shift toward personal mobile devices, more and more of the learning that takes place may be happening outside of the classroom and in the context of a backyard conversation, a walk through campus, or a Taquería in New Mexico.

learners construct knowledge by understanding new information building on their current understanding and expertise. Constructivism contradicts the idea that learning is the transmission of content to a passive receiver. Instead, it views learning as an active process, always based on the learner's current understanding or intellectual paradigm. Knowledge is constructed by assimilating new information into the learner's knowledge paradigm. A learner does not come to a classroom or a course Web site with a mind that is a tabula rasa, a blank slate. Each learner arrives at a learning "site" with some preexisting level of understanding.

Learning science research also highlights the importance of learner engagement, or as the American Psychological Association describes it, intentional learning.1 This means that learners must have a "metaperspective" from which to view and assess their own learning, which is often referred to as metacognition.2 An active learning environment provides the opportunity to assess one's own learning, enabling learners to make decisions about the course, as well as reflect on and assess their progress. In the past, the measure of learning was the final grade (a summative measure). But a final grade is merely a measure of the student's performance on tests. It does not measure the learning that did—or did not—take place. To encourage learning, summative testing or assessments must be combined with formative assessments. Formative assessment is not directly associated with the final grade; it helps learners understand their learning and make decisions about next steps based on that understanding.

research indicating that learning is encouraged when it includes social components such as debate or direct engagement with peers and experts. Learning is strengthened through social interactions, interpersonal relations, and communication with others.

Research indicates that learners need to be active with respect to their own learning process and assessment. Net Gen students' goal and achievement orientation comes into play here: that achievement focus can be directed toward quizzes and exercises that assist learners in evaluating their progress toward learning goals.

Obviously not all forms of learning must be social or team-based. In a variety of learning contexts, individual work is important. It may well be that Net Gen students' strengths are also their weaknesses. The expectation for fast-paced, rapidly shifting interaction coupled with a relatively short attention span may be counterproductive in many learning contexts. Repetition and steady, patient practice—key to some forms of mastery—may prove difficult for Net Gen students. Designing courses for them necessitates balancing these strengths and weaknesses.

We should not neglect the informal for the formal, or assume that Net Gen students somehow will figure out the virtual space on their own. We should connect what happens in the classroom with what happens in informal and virtual spaces.

Simply installing wireless access points and fresh carpeting isn't enough if done in isolation; such improvements pay real dividends only if they are in concert with the institution's overall teaching and learning objectives. It is the vision that generates the design principles that will, in turn, be used to make key decisions about how learning spaces are configured.

The vision and design principles should emphasize the options students have as active participants in the learning process. Design principles should include terms such as analyze, create, criticize, debate, present, and classify—all directed at what the space enables the students to do. For example, students should be able to present materials to the class. Outside class, they should have access to applications and materials that directly support analysis of data, text, and other media. Forums for discussion and critical debate, both real and virtual, are key to encouraging learning and will be looked for by Net Gen students.

Learning spaces should accommodate the use of as many kinds of materials as possible and enable the display of and access to those materials by all participants. Learning space needs to provide the participants—instructors and students alike—with interactive tools that enable exploration, probing, and examination. This might include a robust set of applications installed on the computer that controls the room's displays, as well as a set of communication tools. Since the process of examination and debate leads to discovery and the construction of new knowledge, it could be important to equip spaces with devices that can capture classroom discussion and debate, which can be distributed to all participants for future reference and study.

the end of the class meeting marks a transition from one learning mode to another.

This lecture hall is of relatively recent vintage; its seats and paired tables make it much easier to deploy and use her "tools," which include printouts of the day's reading, as well as a small laptop computer. Her fellow students are doing likewise. Each of them is using some device to access the course's Web site—some with laptops, others with tablet computers, still others with handheld computers. Using wireless connections, they all access the course's Web site and navigate to the site's "voting" page.

a "magic wand," a radio-frequency controller that enables her to operate her computer—as well as many of the classroom's functions—wirelessly, from any point in the room. She can capture anything she writes on the blackboard and make it available to her students on the course Web site. Freed from needing to take extensive notes, the students are able to participate more fully in the class discussion. Finally, the professor is carrying a small recorder that captures her lecture, digitizes the audio, and uploads it to the course Web site for the students to review when they prepare for finals.

Sandra launches the classroom's screen sharing application. Within a few seconds, her computer's screen is projected on the room's main screen. The class discussion focuses on this diagram, and the professor, using a virtual pencil, is able to make notes on the diagram. The diagram and notes are captured and placed on the class Web site for review.

Soon the debate gets stuck; the students can't resolve the issue. The professor goes to the podium, types briefly, and then asks the students to go to a URL to see a question and to choose the answer they feel is correct. The students access the Web page from laptops, handhelds, or wireless IP-based phones. In two minutes they have completed the poll and submitted their responses. The results are quickly tabulated and displayed. The wide diversity of opinion surprises everyone. The professor reframes the issue, without giving the answer, and the students continue to discuss it. She repeats the poll; this time there is more agreement among the students, enabling her to move the discussion forward.

She goes to the podium computer and clicks on a few links, and soon a videoconferencing session is displayed on the right-hand screen. She has arranged to have a colleague of hers "drop in" on the class to discuss a point that is in the colleague's particular area of expertise. The class has a conversation with the expert, who is at large research institution more than 500 miles away. Students listen to the expert's comments and are able to pose questions using one of the three cordless microphones available to the class. On the left-hand screen, the visiting professor shows some images and charts that help explain the concepts under discussion.

the other students in her class have signed up for most of the slots, conferring with friends using chat programs to ensure that they sign up for the same lab slots.

The discussion pocket is the college's term for a small, curved space with a table and bench to accommodate a meeting of four or five people. Found outside the newer classrooms, they are handy for informal, spontaneous discussions. Sandra's group moves into the pocket and for the next 15 minutes continue their "spill over" discussion of the class.

hey are able to have an audio chat; Sandra's friend is in her dorm room, and Sandra is in a remote corner of the library where conversation will not disturb others. As their discussion progresses, they go to the course's Web site and launch the virtual whiteboard to diagram some concepts. They develop a conceptual diagram—drawing, erasing, and revising it until they agree the diagram is correct. They both download a copy. Sandra volunteers to work on polishing the diagram and will leave a copy of the final diagram in her share folder in her online portfolio "locker

The underlying theme remains the same, however: cultivating learning practices consistent with learning theory and aligned with the habits and expectations of Net Gen students

For most higher education institutions, the lecture hall will not disappear; the challenge is to develop a new generation of lecture hall, one that enables Net Gen students and faculty to engage in enlivened, more interactive experiences. If the lecture hall is integrated with other spaces—physically as well as virtually—it will enable participants to sustain the momentum from the class session into other learning contexts. The goal is not to do away with the traditional classroom, but rather to reinvent and to integrate it with the other learning spaces, moving toward a single learning environment.

Learning theory is central to any consideration of learning spaces; colleges and universities cannot afford to invest in "fads" tailored to the Net Gen student that might not meet the needs of the next generation.

For example, start with the Net Gen students' focus on goals and achievement. That achievement orientation ties to learning theory's emphasis on metacognition, where learners assess their progress and make active decisions to achieve learning goals. Learning space design could support this by providing contact with people who can provide feedback: tutors, consultants, and faculty. This could, in turn, be supported in the IT environment by making formative self-tests available, as well as an online portfolio, which would afford students the opportunity to assess their overall academic progress.

As institutions create an anywhere, anytime IT infrastructure, opportunities arise to tear down silos and replace them with a more ubiquitous learning environment. Using laptops and other networked devices, students and faculty are increasingly able to carry their entire working environment with them. To capitalize on this, campus organizations must work collaboratively to create a more integrated work environment for the students and faculty, one that better serves the mobile Net Gen students as well as a faculty faced with the initial influx of these students into their ranks

One of the key variables is the institution itself. Learning spaces are institutional in scope—their implementation involves the institution's culture, tradition, and mission.

The starting point for rethinking learning spaces to support Net Gen students begins with an underlying vision for the learning activities these spaces should support. This vision should be informed by learning theory, as well as by recognition of the characteristics of the students and faculty who use these spaces.

So Professor Shankar has begun inserting links to specific portions of Professor Lewin’s course, and, “since any mistake would affect larger numbers of students listening online,” he says, he thinks harder about every topic he teaches in the classroom.

His intense, animated ruminations — the title of his course is “Death” — have brought fan mail from Mexico, Iraq, Korea and China. Several months ago, he got a response from somebody suffering from a brain injury and who was using the lectures to exercise his mind. “I don’t think anyone knows what this will do to education 15 years from now,” Professor Kagan says. “But even if it does nothing more than that, that’s enough.”

The backers of free courseware acknowledge the benefit of self-enrichment. Still, they say they expect open education not only to expand access to information but also to lead to success in higher education, particularly among low-income students and those who are first in their family to go to college.

Carnegie Mellon’s Open Learning Initiative is working with teams of faculty members, researchers on learning and software engineers to develop e-courses designed to improve the educational experience.

Carnegie Mellon is working with community colleges to build four more courses, with the three-year goal of 25 percent more students passing when the class is bolstered by the online instruction.

The intended user is the beginning college student, whom Dr. Smith describes as “someone with limited prior knowledge in a college subject and with little or no experience in successfully directing his or her own learning.”

. “We now have the technology that enables us to go back to what we all know is the best educational experience: personalized, interactive engagement,” Dr. Smith says.

That won’t happen, and in the terms-of-use section of Open Yale Courses, the university makes that clear. Besides not granting degrees or certificates, open courses do not offer direct access to faculty. They, in other words, are strictly “for those who wish to learn,” as the Web site says. “Its purpose is not to duplicate a Yale education.”

Open courseware is a classic example of disruptive technology, which, loosely defined, is an innovation that comes along one day to change a product or service, often standing an industry on its head. Craigslist did this to newspapers by posting classified ads for free. And the music industry got blindsided when iTunes started unbundling songs from albums and selling them for 99 cents apiece.

Mr. Schonfeld sees still more potential in “unbundling” the four elements of educating: design of a course, delivery of that course, delivery of credit and delivery of a degree. “Traditionally, they’ve all lived in the same institutional setting.” Must all four continue to live together, or can one or more be outsourced?

P2PU’s mission isn’t to develop a model and stick with it. It is to “experiment and iterate,” says Ms. Paharia, the former executive director of Creative Commons. She likes to talk about signals, a concept borrowed from economics. “Having a degree is a signal,” she says. “It’s a signal to employers that you’ve passed a certain bar.” Here’s the radical part: Ms. Paharia doesn’t think degrees are necessary. P2PU is working to come up with alternative signals that indicate to potential employers that an individual is a good thinker and has the skills he or she claims to have — maybe a written report or an online portfolio.

David Wiley, associate professor of instructional psychology and technology at Brigham Young University, is an adviser to P2PU. For the past several years, he has been referring to “the disaggregation of higher education,” the breaking apart of university functions. Dr. Wiley says that models like P2PU address an important component missing from open courseware: human support. That is, when you have a question, whom can you ask? “No one gets all the way through a textbook without a dozen questions,” he says. “Who’s the T.A.? Where’s your study group?” “If you go to M.I.T. OpenCourseWare, there’s no way to find out who else is studying the same material and ask them for help,” he says. At P2PU, a “course organizer” leads the discussion but “you are working together with others, so when you have a question you can ask any of your peers. The core idea of P2PU is putting people together around these open courses.”

Mr. Reshef’s plan is to “take anyone, anyone whatsoever,” as long as they can pass an English orientation course and a course in basic computer skills, and have a high school diploma or equivalent. The nonprofit venture has accepted, and enrolled, 380 of 3,000 applicants, and is trying to raise funds through microphilanthropy — “$80 will send one student to UoPeople for a term” — through social networking.

Mr. Reshef has used $1 million of his own money to start the University of the People, which taps open courses that other universities have put online and relies on student interaction to guide learning; students even grade one another’s papers.

Students might consider taking the questions in the back of the textbook chapter and try to answer them before reading the chapter. (If there are no questions, convert the section headings to questions. If the heading is Pavlovian Conditioning, ask yourself What is Pavlovian conditioning?). Then read the chapter and answer the questions while reading it. When the chapter is finished, go back to the questions and try answering them again. For any you miss, restudy that section of the chapter. Then wait a few days and try to answer the questions again (restudying when you need to). Keep this practice up on all the chapters you read before the exam and you will be have learned the material in a durable manner and be able to retrieve it long after you have left the course.
