In “developed” societies, we are so accustomed to centralized control over learning that it has become functionally invisible to us, and most people accept it as natural, inevitable, and consistent with the principles of freedom and democracy.   We assume that this central authority, because it is associated with something that seems like an unequivocal good – “education” – must itself be fundamentally good, a sort of benevolent dictatorship of the intellect. 

We endorse strict legal codes which render this process compulsory, and in a truly Orwellian twist, many of us now view it as a fundamental human right to be legally compelled to learn what a higher authority tells us to learn.

And yet the idea of centrally-controlled education is as problematic as the idea of centrally-controlled media – and for exactly the same reasons.

The First Amendment of the U.S. Constitution was designed to protect all forms of communication, information-sharing, knowledge, opinion and belief – what the Supreme Court has termed “the sphere of intellect and spirit” – from government control.

by the mid-19th century, with Indians still to conquer and waves of immigrants to assimilate, the temptation to find a way to manage the minds of an increasingly diverse and independent-minded population became too great to resist, and the idea of the Common School was born.

We would keep our freedom of speech and press, but first we would all be well-schooled by those in power.

A deeply democratic idea — the free and equal education of every child — was wedded to a deeply anti-democratic idea — that this education would be controlled from the top down by state-appointed educrats.

The fundamental point of the Occupy Wall Street movement is that the apparatus of democratic government has been completely bought and paid for by a tiny number of grotesquely wealthy individuals, corporations, and lobbying groups.  Our votes no longer matter.  Our wishes no longer count.  Our power as citizens has been sold to the highest bidder.

Our kids are so drowned in disconnected information that it becomes quite random what they do and don’t remember, and they’re so overburdened with endless homework and tests that they have little time or energy to pay attention to what’s happening in the world around them.

If in ten years we can create Wikipedia out of thin air, what could we create if we trusted our children, our teachers, our parents, our neighbors, to generate community learning webs that are open, alive, and responsive to individual needs and aspirations?  What could we create if instead of trying to “scale up” every innovation into a monolithic bureaucracy we “scaled down” to allow local and individual control, freedom, experimentation, and diversity?

The most academically “gifted” students excel at obedience, instinctively shaping their thinking to the prescribed curriculum and unconsciously framing out of their awareness ideas that won’t earn the praise of their superiors.  Those who resist sitting still for this process are marginalized, labeled as less intelligent or even as mildly brain-damaged, and, increasingly, drugged into compliance.

the very root, the very essence, of any theory of democratic liberty is a basic trust in the fundamental intelligence of the ordinary person.   Democracy rests on the premise that the ordinary person — the waitress, the carpenter, the shopkeeper — is competent to make her own judgments about matters of domestic policy, international affairs, taxes, justice, peace, and war, and that the government must abide by the decisions of ordinary people, not vice versa.  Of course that’s not the way our system really works, and never has been.   But most of us recall at some deep level of our beings that any vision of a just world relies on this fundamental respect for the common sense of the ordinary human being.

This is what we spend our childhood in school unlearning. 

If before we reach the age of majority we must submit our brains for twelve years of evaluation and control by government experts, are we then truly free to exercise our vote according to the dictates of our own common sense and conscience?  Do we even know what our own common sense is anymore?

We live in a country where a serious candidate for the Presidency is unaware that China has nuclear weapons, where half the population does not understand that Saddam Hussein had nothing to do with 9/11, where nobody pays attention as Congress dismantles the securities regulations that limit the power of the banks, where 45% of American high school students graduate without knowing that the First Amendment of the Constitution guarantees freedom of the press.   At what point do we begin to ask ourselves if we are trying to control quality in the wrong way?

Human beings, collaborating with one another in voluntary relationships, communicating and checking and counter-checking and elaborating and expanding on one another’s knowledge and intelligence, have created a collective public resource more vast and more alive than anything that has ever existed on the planet.

But this is not a paeon to technology; this is about what human intelligence is capable of when people are free to interact in open, horizontal, non-hierarchical networks of communication and collaboration.

Positive social change has occurred not through top-down, hierarchically controlled organizations, but through what the Berkana Institute calls “emergence,” where people begin networking and forming voluntary communities of practice. When the goal is to maximize the functioning of human intelligence, you need to activate the unique skills, talents, and knowledge bases of diverse individuals, not put everybody through a uniform mill to produce uniform results. 

You need a non-punitive structure that encourages collaboration rather than competition, risk-taking rather than mistake-avoidance, and innovation rather than repetition of known quantities.

if we really want to return power to the 99% in a lasting, stable, sustainable way, we need to begin the work of creating open, egalitarian, horizontal networks of learning in our communities.

They are taught to focus on competing with each other and gaming the system rather than on gaining a deep understanding of the way power flows through their world.

And what could we create, what ecological problems could we solve, what despair might we alleviate, if instead of imposing our rigid curriculum and the destructive economy it serves on the entire world, we embraced as part of our vast collective intelligence the wisdom and knowledge of the world’s thousands of sustainable indigenous cultures?

They knew this about their situation: nobody was on their side.  Certainly not the moneyed classes and the economic system, and not the government, either.  So if they were going to change anything, it had to come out of themselves.

As our climate heats up, as mountaintops are removed from Orissa to West Virginia, as the oceans fill with plastic and soils become too contaminated to grow food, as the economy crumbles and children go hungry and the 0.001% grows so concentrated, so powerful, so wealthy that democracy becomes impossible, it’s time to ask ourselves; who’s educating us?  To what end?  The Adivasis are occupying their forests and mountains as our children are occupying our cities and parks.  But they understand that the first thing they must take back is their common sense. 

They must occupy their brains.

Isn’t it time for us to do the same?

subjecting us to pop quizzes, cold calls, and pedagogical tactics that during an in-the-flesh seminar would have taken precious minutes of class time to arrange.

Lectures, Kosslyn says, are cost-effective but pedagogically unsound. “A great way to teach, but a terrible way to learn.”

when you have a noncurated academic experience, you effectively don’t get educated.

Liberal-arts education is about developing the intellectual capacity of the individual, and learning to be a productive member of society. And you cannot do that without a curriculum.”

“The freshman year [as taught at traditional schools] should not exist,” Nelson says, suggesting that MOOCs can teach the basics. “Do your freshman year at home.”) Instead, Minerva’s first-year classes are designed to inculcate what Nelson calls “habits of mind” and “foundational concepts,” which are the basis for all sound systematic thought. In a science class, for example, students should develop a deep understanding of the need for controlled experiments. In a humanities class, they need to learn the classical techniques of rhetoric and develop basic persuasive skills. The curriculum then builds from that foundation.

What, he asks, does it mean to be educated?

methods will be tested against scientifically determined best practices

Subsidies, Nelson says, encourage universities to enroll even students who aren’t likely to thrive, and to raise tuition, since federal money is pegged to costs.

We have numerous sound, reproducible experiments that tell us how people learn, and what teachers can do to improve learning.” Some of the studies are ancient, by the standards of scientific research—and yet their lessons are almost wholly ignored.

ask a student to explain a concept she has been studying, the very act of articulating it seems to lodge it in her memory. Forcing students to guess the answer to a problem, and to discuss their answers in small groups, seems to make them understand the problem better—even if they guess wrong.

e traditional concept of “cognitive styles”—visual versus aural learners, those who learn by doing versus those who learn by studying—is muddled and wrong.

Continuously upgrade educators' classroom technology skills as a pre-requisite of "highly effective" teaching

Home Advocacy Top Ten in '10: ISTE's Education Technology Priorities for 2010 Through a common focus on boosting student achievement and closing the achievement gap, policymakers and educators alike are now reiterating their commitment to the sorts of programs and instructional efforts that can have maximum effect on instruction and student outcomes. This commitment requires a keen understanding of both past accomplishment and strategies for future success. Regardless of the specific improvement paths a state or school district may chart, the use of technology in teaching and learning is non-negotiable if we are to make real and lasting change.  With growing anticipation for Race to the Top (RttT) and Investing in Innovation (i3) awards in 2010, states and school districts are seeing increased attention on educational improvement, backed by financial support through these grants. As we think about plans for the future, the International Society for Technology in Education (ISTE) has identified 10 priorities essential for making good on this commitment in 2010: 1. Establish technology in education as the backbone of school improvement . To truly improve our schools for the long term and ensure that all students are equipped with the knowledge and skills necessary to achieve in the 21st century, education technology must permeate every corner of the learning process. From years of research, we know that technology can serve as a primary driver for systemic school improvement, including school leadership, an improved learning culture and excellence in professional practice. We must ensure that technology is at the foundation of current education reform efforts, and is explicit and clear in its role, mission, and expected impact. 2. Leverage education technology as a gateway for college and career readiness . Last year, President Obama established a national goal of producing the highest percentage of college graduates in the world by the year 2020. To achieve this goal in the next 10 years, we must embrace new instructional approaches that both increase the college-going rates and the high school graduation rates. By effectively engaging learning through technology, teachers can demonstrate the relevance of 21st century education, keeping more children in the pipeline as they pursue a rigorous, interesting and pertinent PK-12 public education. 3. Ensure technology expertise is infused throughout our schools and classrooms.  In addition to providing all teachers with digital tools and content we must ensure technology experts are integrated throughout all schools, particularly as we increase focus and priority on STEM (science-technology-engineering-mathematics) instruction and expand distance and online learning opportunities for students. Just as we prioritize reading and math experts, so too must we place a premium on technology experts who can help the entire school maximize its resources and opportunities. To support these experts, as well as all educators who integrate technology into the overall curriculum, we must substantially increase our support for the federal Enhancing Education Through Technology (EETT) program.  EETT provides critical support for on-going professional development, implementation of data-driven decision-making, personalized learning opportunities, and increased parental involvement. EETT should be increased to $500 million in FY2011. 4. Continuously upgrade educators' classroom technology skills as a pre-requisite of "highly effective" teaching . As part of our nation's continued push to ensure every classroom is led by a qualified, highly effective teacher, we must commit that all P-12 educators have the skills to use modern information tools and digital content to support student learning in content areas and for student assessment. Effective teachers in the 21st Century should be, by definition, technologically savvy teachers. 5. Invest in pre-service education technology

Online learning allows for flexibility of access, from anywhere and usually at anytime—essentially, it allows participants to collapse time and space (Cole, 2000)—however, the learning materials must be designed properly to engage the learner and promote learning.

Cognitive psychology claims that learning involves the use of memory, motivation, and thinking, and that reflection plays an important part in learning.

The development of effective online learning materials should be based on proven and sound learning theories.

Early computer learning systems were designed based on a behaviorist approach to learning. The behaviorist school of thought, influenced by Thorndike (1913), Pavlov (1927), and Skinner (1974), postulates that learning is a change in observable behavior caused by external stimuli in the environment (Skinner, 1974).

Therefore, before any learning materials are developed, educators must, tacitly or explicitly, know the principles of learning and how students learn.

Constructivist theorists claim that learners interpret information and the world according to their personal reality, and that they learn by observation, processing, and interpretation, and then personalize the information into personal knowledge (Cooper, 1993; Wilson, 1997).

The design of online learning materials can include principles from all three. According to Ertmer and Newby (1993), the three schools of thought can in fact be used as a taxonomy for learning. Behaviorists' strategies can be used to teach the “what” (facts), cognitive strategies can be used to teach the “how” (processes and principles), and constructivist strategies can be used to teach the “why” (higher level thinking that promotes personal meaning and situated and contextual learning).

The behaviorist school sees the mind as a “black box,” in the sense that a response to a stimulus can be observed quantitatively, totally ignoring the effect of thought processes occurring in the mind.

Learners should be told the explicit outcomes of the learning so that they can set expectations and can judge for themselves whether or not they have achieved the outcome of the online lesson. 2.  Learners must be tested to determine whether or not they have achieved the learning outcome. Online testing or other forms of testing and assessment should be integrated into the learning sequence to check the learner's achievement level and to provide appropriate feedback. 3.  Learning materials must be sequenced appropriately to promote learning. The sequencing could take the form of simple to complex, known to unknown, and knowledge to application. 4.  Learners must be provided with feedback so that they can monitor how they are doing and take corrective action if required.

Cognitivists see learning as an internal process that involves memory, thinking, reflection, abstraction, motivation, and meta-cognition.

Online instruction must use strategies to allow learners to attend to the learning materials so that they can be transferred from the senses to the sensory store and then to working memory.

Online learning strategies must present the materials and use strategies to enable students to process the materials efficiently.

information should be organized or chunked in pieces of appropriate size to facilitate processing.

Use advance organizers to activate an existing cognitive structure or to provide the information to incorporate the details of the lesson (Ausubel, 1960).

Use pre-instructional questions to set expectations and to activate the learners' existing knowledge structure.

Use prerequisite test questions to activate the prerequisite knowledge structure required for learning the new materials.

To facilitate deep processing, learners should be asked to generate the information maps during the learning process or as a summary activity after the lesson (Bonk & Reynolds, 1997).

The cognitive school recognizes the importance of individual differences, and of including a variety of learning strategies in online instruction to accommodate those differences

The Kolb Learning Style Inventory (LSI) (Kolb, 1984) looks at how learners perceive and process information, whereas the Myers-Briggs Type Indicator (Myers, 1978) uses dichotomous scales to measure extroversion versus introversion, sensing versus intuition, thinking versus feeling, and judging versus perception. In the following discussion, we consider the Kolb Learning Style Inventory.

Attention: Capture the learners' attention at the start of the lesson and maintain it throughout the lesson. The online learning materials must include an activity at the start of the learning session to connect with the learners. Relevance: Inform learners of the importance of the lesson and how taking the lesson could benefit them. Strategies could include describing how learners will benefit from taking the lesson, and how they can use what they learn in real-life situations. This strategy helps to contextualize the learning and make it more meaningful, thereby maintaining interest throughout the learning session. Confidence: Use strategies such as designing for success and informing learners of the lesson expectations. Design for success by sequencing from simple to complex, or known to unknown, and use a competency-based approach where learners are given the opportunity to use different strategies to complete the lesson. Inform learners of the lesson outcome and provide ongoing encouragement to complete the lesson. Satisfaction: Provide feedback on performance and allow learners to apply what they learn in real-life situations. Learners like to know how they are doing, and they like to contextualize what they are learning by applying the information in real life.

Online strategies that facilitate the transfer of learning should be used to encourage application in different and real-life situations.

Constructivists see learners as being active rather than passive.

it is the individual learner's interpretation and processing of what is received through the senses that creates knowledge.

“the process of using a prior interpretation to construe a new or revised interpretation of the meaning of one's experience in order to guide future action” (p. 12).

Learning should be an active process. Keeping learners active doing meaningful activities results in high-level processing, which facilitates the creation of personalized meaning. Asking learners to apply the information in a practical situation is an active process, and facilitates personal interpretation and relevance.

Learners should construct their own knowledge rather than accepting that given by the instructor.

Collaborative and cooperative learning should be encouraged to facilitate constructivist learning (H

When assigning learners for group work, membership should be based on the expertise level and learning style of individual group members, so that individual team members can benefit from one another's strengths.

  Learners should be given control of the learning process

Learners should be given time and opportunity to reflect.

Learning should be made meaningful for learners. The learning materials should include examples that relate to students, so that they can make sense of the information.

Learning should be interactive to promote higher-level learning and social presence, and to help develop personal meaning. According to Heinich et al. (2002), learning is the development of new knowledge, skills, and attitudes as the learner interacts with information and the environment. Interaction is also critical to creating a sense of presence and a sense of community for online learners, and to promoting transformational learning (Murphy & Cifuentes, 2001). Learners receive the learning materials through the technology, process the information, and then personalize and contextualize the information.

Figure 1-6. Components of effective online learning.

Behaviorist strategies can be used to teach the facts (what); cognitivist strategies to teach the principles and processes (how); and constructivist strategies to teach the real-life and personal applications and contextual learning. There is a shift toward constructive learning, in which learners are given the opportunity to construct their own meaning from the information presented during the online sessions. The use of learning objects to promote flexibility and reuse of online materials to meet the needs of individual learners will become more common in the future. Online learning materials will be designed in small coherent segments, so that they can be redesigned for different learners and different contexts. Finally, online learning will be increasingly diverse to respond to different learning cultures, styles, and motivations.

Online instruction occurs when learners use the Web to go through the sequence of instruction, to complete the learning activities, and to achieve learning outcomes and objectives (Ally, 2002; Ritchie & Hoffman, 1997).

When faculty of a major Chinese university asked Plucker to identify trends in American education, he described our focus on standardized curriculum, rote memorization, and nationalized testing. “After my answer was translated, they just started laughing out loud,” Plucker says. “They said, ‘You’re racing toward our old model. But we’re racing toward your model, as fast as we can.’ ”

The argument that we can’t teach creativity because kids already have too much to learn is a false trade-off. Creativity isn’t about freedom from concrete facts. Rather, fact-finding and deep research are vital stages in the creative process.

When you try to solve a problem, you begin by concentrating on obvious facts and familiar solutions, to see if the answer lies there. This is a mostly left-brain stage of attack. If the answer doesn’t come, the right and left hemispheres of the brain activate together. Neural networks on the right side scan remote memories that could be vaguely relevant. A wide range of distant information that is normally tuned out becomes available to the left hemisphere, which searches for unseen patterns, alternative meanings, and high-level abstractions. Having glimpsed such a connection, the left brain must quickly lock in on it before it escapes. The attention system must radically reverse gears, going from defocused attention to extremely focused attention. In a flash, the brain pulls together these disparate shreds of thought and binds them into a new single idea that enters consciousness. This is the “aha!” moment of insight, often followed by a spark of pleasure as the brain recognizes the novelty of what it’s come up with. Now the brain must evaluate the idea it just generated. Is it worth pursuing? Creativity requires constant shifting, blender pulses of both divergent thinking and convergent thinking, to combine new information with old and forgotten ideas. Highly creative people are very good at marshaling their brains into bilateral mode, and the more creative they are, the more they dual-activate.

those who diligently practice creative activities learn to recruit their brains’ creative networks quicker and better

Creativity has always been prized in American society, but it’s never really been understood. While our creativity scores decline unchecked, the current national strategy for creativity consists of little more than praying for a Greek muse to drop by our houses. The problems we face now, and in the future, simply demand that we do more than just hope for inspiration to strike. Fortunately, the science can help: we know the steps to lead that elusive muse right to our doors.

What’s common about successful programs is they alternate maximum divergent thinking with bouts of intense convergent thinking, through several stages. Real improvement doesn’t happen in a weekend workshop. But when applied to the everyday process of work or school, brain function improves.

kids demonstrated the very definition of creativity: alternating between divergent and convergent thinking, they arrived at original and useful ideas. And they’d unwittingly mastered Ohio’s required fifth-grade curriculum—from understanding sound waves to per-unit cost calculations to the art of persuasive writing. “You never see our kids saying, ‘I’ll never use this so I don’t need to learn it,’ ” says school administrator Maryann Wolowiec. “Instead, kids ask, ‘Do we have to leave school now?’ ” Two weeks ago, when the school received its results on the state’s achievement test, principal Traci Buckner was moved to tears. The raw scores indicate that, in its first year, the school has already become one of the top three schools in Akron, despite having open enrollment by lottery and 42 percent of its students living in poverty.

project-based learning

highly creative adults frequently grew up with hardship. Hardship by itself doesn’t lead to creativity, but it does force kids to become more flexible—and flexibility helps with creativity.

When creative children have a supportive teacher—someone tolerant of unconventional answers, occasional disruptions, or detours of curiosity—they tend to excel. When they don’t, they tend to underperform and drop out of high school or don’t finish college at high rates. They’re quitting because they’re discouraged and bored, not because they’re dark, depressed, anxious, or neurotic. It’s a myth that creative people have these traits. (Those traits actually shut down creativity; they make people less open to experience and less interested in novelty.) Rather, creative people, for the most part, exhibit active moods and positive affect. They’re not particularly happy—contentment is a kind of complacency creative people rarely have. But they’re engaged, motivated, and open to the world.

solutions emerge from a healthy marketplace of ideas, sustained by a populace constantly contributing original ideas and receptive to the ideas of others

The age-old belief that the arts have a special claim to creativity is unfounded.

When scholars gave creativity tasks to both engineering majors and music majors, their scores laid down on an identical spectrum, with the same high averages and standard deviations. Inside their brains, the same thing was happening—ideas were being generated and evaluated on the fly.

those who diligently practice creative activities learn to recruit their brains’ creative networks quicker and better. A lifetime of consistent habits gradually changes the neurological pattern.

The home-game version of this means no longer encouraging kids to spring straight ahead to the right answer

The new view is that creativity is part of normal brain function.

“As a child, I never had an identity as a ‘creative person,’ ” Schwarzrock recalls. “But now that I know, it helps explain a lot of what I felt and went through.”

In China there has been widespread education reform to extinguish the drill-and-kill teaching style. Instead, Chinese schools are also adopting a problem-based learning approach.

there is one crucial difference between IQ and CQ scores. With intelligence, there is a phenomenon called the Flynn effect—each generation, scores go up about 10 points. Enriched environments are making kids smarter. With creativity, a reverse trend has just been identified and is being reported for the first time here: American creativity scores are falling.

There are many horses in the educational technology race. The ones to bet on are adaptive textbooks and independent certification.

I do not believe that educators fully understand the process of social learning in the classroom. We do not know exactly what factors make the difference between a classroom where students are of significant help to one another and one where students provide little assistance or even hold one another back
