Just ten years ago, we would not have imagined the need for “a guide to gathering, preserving, and presenting the past on the web.” Indeed, few of us knew the web existed. Even the editors of Wired ignored it in their inaugural issue.4 Ten years ago, we would have been objects of curiosity, if not derision, if we had proposed such a project.

The first advantage of digital media for historians is storage capacity—digital media can condense unparalleled amounts of data into small spaces.

The most profound effect, however, may be on tomorrow’s historians. The rapidly dropping price of data storage has led computer scientists like Michael Lesk (a cyber-enthusiast to be sure) to claim that in the future, “there will be enough disk space and tape storage in the world to store everything people write, say, perform, or photograph.” In other words, why delete anything from the current historical record if it costs so little save it? How might our history writing be different if all historical evidence were available?

a second and even more important advantage—accessibility.

Our web server at the Center for History and New Media (CHNM) gets about three-quarters of a million hits a day, but on September 11, 2002 (when people looking to commemorate the attacks of the previous year descended in droves on the September 11 Digital Archive that we organized in collaboration with the American Social History Project), we handled eight million hits—a more than ten-fold increase with no additional costs

But the flexibility of digital data lies not just in the ability to encompass different media. It also resides in the ability of the same data to assume multiple guises instantaneously. Although language translation software is still primitive, we are moving toward a time when words in one tongue can be automatically translated into another—perhaps not perfectly but effectively enough.

Flexibility transforms the experience of consuming history, but digital media—because of their openness and diversity—also alters the conditions and circumstances of producing history. The computer networks that have come together in the World Wide Web are not only more open to a global audience of history readers than any other previous medium, they are also more open to history authors. A 2004 study found that almost half of the Internet users in the United States have created online content by building websites, creating blogs, and posting and sharing files.

quantitative advantages—we can do more, reach more people, store more data, give readers more varied sources; we can get more historical materials into classrooms, give students more access to formerly cloistered documents, hear from more perspectives.

o consider these “expressive” qualities we need to think, for example, about the manipulability of digital media—the possibility of manipulating historical data with electronic tools as a way of finding things that were not previously evident. At the moment, the most powerful of those tools for historians is the simplest—the ability to search through vast quantities of text for particular strings of words. The word search capabilities of JSTOR, the online database of 460 scholarly periodicals, makes possible a kind of intellectual history that cannot be done as readily in print sources.

Digital media also differ from many other older media in their interactivity—a product of the web being, unlike broadcast television, a two-way medium, in which every point of consumption can also be a point of production. This interactivity enables multiple forms of historical dialogue—among professionals, between professionals and nonprofessionals, between teachers and students, among students, among people reminiscing about the past—that were possible before but which are not only simpler but potentially richer and more intensive in the digital medium. Many history websites offer opportunities for dialogue and feedback. The level of response has varied widely, but the experience so far suggests how we might transform historical practice—the web becomes a place for new forms of collaboration, new modes of debate, and new modes of collecting evidence about the past. At least potentially, digital media transform the traditional, one-way reader/writer, producer/consumer relationship. Public historians, in particular, have long sought for ways to “share authority” with their audiences; the web offers an ideal medium for that sharing and collaboration.16

inally, we note the hypertextuality, or nonlinearity, of digital media—the ease of moving through narratives or data in undirected and multiple ways.

the problems of quality and authenticity emerge

Moreover, in general, the web is more likely to be right than wrong.

Consider, for example, the famous “photograph” of Lee Harvey Oswald and Jack Ruby playing rock music together in a Dallas basement. Such fake photographs have a long history; Stalin’s photo retouchers, for example, spent considerable time airbrushing Trotsky out of the historical record. But the transformation of the original Bob Jackson photo of Ruby shooting Oswald into “In-A-Gadda-Da-Oswald” did not require a skilled craftsman. George Mahlberg created it with Photoshop in forty minutes and it quickly spread across the World Wide Web, popping up in multiple contexts that erase the credit of the “original” counterfeiter.20

Is there some way to police the boundaries of historical quality and authenticity on the web? Could we stop a thousand historical flowers—amateur, professional, commercial, crackpot—from blooming on the web? Would we want to? Of course, issues of quality, authenticity, and authority pre-date the Internet. But digital media undercut an existing structure of trust and authority and we, as historians and citizens, have yet to establish a new structure of historical legitimation and authority. When you move your history online, you are entering a less structured and controlled environment than the history monograph, the scholarly journal, the history museum, or the history classroom. That can have both positive and unsettling implications.

Digital enthusiasts assume that the online environment is intrinsically more “interactive” than one-way, passive media like television. But digital technology could, in fact, foster a new couch potatoÐlike passivity. Efforts to create nuanced interactive history projects sometimes become quixotic when the producers confront the fact that computers are good at yes and no and right and wrong, whereas historians prefer words like “maybe,” “perhaps,” and “it is more complicated than that.” Thus the most common form of historical interactivity on the web is the multiple-choice test. But the high-budget version is little better. Take, for example, the History Channel’s website Modern Marvel’s Boys’ Toys, which is a combination of watching the cable channel and playing a video game. The true interactivity here comes when you click on the “shop” button. As legal scholar Lawrence Lessig has written pessimistically: “There are two futures in front of us, the one we are taking and the one we could have. The one we are taking is easy to describe. Take the Net, mix it with the fanciest TV, add a simple way to buy things, and that’s pretty much it.” At the same time, some wonder whether we really want to foster “interactivity” at all, arguing that it fails to provide the critical experience of understanding, of getting inside the thoughts and experiences of others. The literary critic Harold Bloom, for example, argues that whereas linear fiction allows us to experience more by granting us access to the lives and thoughts of those different from ourselves, interactivity only permits us to experience more of ourselves.25

Another concern stems more from the production than the consumption side. Will amateur and academic historians be able to compete with well-funded commercial operators—like the History Channel—for attention on the Net?

Only about six percent of teachers are ineffective, she continues. For the remaining 94 percent, the emphasis should shift from ratings to learning.

And what do we know about professional learning? That it requires: • Active intellectual engagement – That is, self-assessment, reflection on practice, and on-going conversations; • Trust – “Fear shuts people down,” says Danielson. “Learning, after all, entails vulnerability. The culture of the school and of the district must be one that encourages risk-taking.” • Challenge – “The culture must include an expectation that every teacher will engage in a career-long process of learning,” she says, “one that is never ‘finished.’ Teaching is simply too complex for anyone to believe that there is no more to learn.” • Teacher collaboration – PD and supervisory suggestions rarely drive classroom improvements, says Danielson. “Overwhelmingly, most teachers report that they learn more from their colleagues than from an ‘expert’ in a workshop… or being directed by a supervisor to read a certain book or take a particular course.” Most often, classroom improvement comes from working with colleagues analyzing student work and planning curriculum.

a new system should include: -   An emphasis on professional learning in a culture of trust and inquiry; -   A career ladder from probationary to continuing status after about three years; from that point on, the main emphasis becomes professional learning; -   Differentiation in the evaluation system, with novice teachers getting support from a mentor and being evaluated every year; -   Career teachers assessed periodically to ensure continuing quality; -   Teacher leadership positions (mentor, instructional coach, team leader) for which experienced teachers in good standing are eligible to apply; these come with training and support, extra compensation, or released time during the regular school day; -   The ability to identify seriously underperforming teachers, support their improvement, and if sufficient progress isn’t made, deny them tenure or continuing employment.

“Former service members tend to be committed to their students and tenacious in their efforts to improve,” say Parham and Gordon. Some early studies suggest that over time, veterans are stronger in classroom management, instructional practices, and student results.

Veterans who have had life-and-death combat experiences “tend to have low tolerance for petty politics in schools or for initiatives that seem unrelated to educating students. Former service members may sometimes seem overly assertive in discussions with colleagues.”

Veterans entering the classroom may feel like novices and have to adjust to their students not snapping to attention when given an order.

Veterans who are used to explicit operating procedures have to decode the unspoken expectations on how to relate to colleagues, handle student discipline, deal with parent concerns, get supplies, and get help.

“Discussions of shared experiences, shared values, and shared goals can help veterans and other teachers begin to build relationships.”

This might consist of a well-chosen mentor (similar to their “battle buddy” in the military), a support team (perhaps a grade-level or subject team that meets regularly), and a support network with other veterans in the school or district.

Veterans need an especially thorough briefing as they enter a new setting, including policies, procedures (copying machines, grading, and more), formal and informal rules, and a map of the school.

up to speed on teaching priorities, curriculum breadth versus depth, dealing with student differences, lesson planning, instructional materials, and, of course, discipline.

Support for this common challenge can come from peer coaching, observing expert teachers, workshops, articles and books, and seminars.

Rather, the mastery of new concepts happens in fits and starts. “Content should not be kept from students because it is ‘developmentally inappropriate,’” says the report. “To answer the question ‘is the student ready?’ it’s best to consider ‘has the student mastered the prerequisites?’”

Effective teachers make content explicit through carefully paced explanation, modeling, and examples; present new information through multiple modalities; and make good use of worked problems.

Effective teachers assign tasks that require explanation or require students to organize material in meaningful ways. Stories and mnemonics are also helpful in getting students to impose meaning on hard-to-remember content.

we shouldn’t push skeptical students to say, “Natural selection is one of the most important ways species came to be differentiated.” Better for them to say, “Most scientists think natural selection is one of the best explanations.”

Practice is essential to learning new facts, but not all practice is equally effective.

Frequent quizzes with low stakes, and students testing themselves, help establish long-term retention through the “retrieval effect.”

Each subject has basic facts that support higher-level learning by freeing working memory and illuminating applications.

Good feedback is specific and clear, focused on the task rather than the student, explanatory, and directed toward improvement rather than merely verifying performance.

To transfer learning to a novel problem, students need to know the problem’s context and its underlying structure.

Explicitly comparing the examples helps students remember the underlying similarities. With multi-step procedures, students need to identify and label the sub-steps so they can apply them to similar problems. It’s also helpful to alternate concrete examples and abstract representations.

Motivation is improved if students believe that intelligence and ability can be improved through hard work, and if adults respond to successful work by praising effective effort rather than innate ability. It’s also helpful for teachers to set learning goals (e.g., mastering specific material) rather than performance goals (competing with others or vying for approval).

Intrinsic motivation leads to better long-term outcomes than extrinsic motivation.

It’s difficult to gauge one’s own learning and understanding. That’s why students need to learn how to monitor their own learning through assessments, self-testing, and explanation.

Students will be more motivated and successful when they believe they belong and are accepted.

Teachers need to recognize and dispel a set of incorrect beliefs about teaching and learning: -   Misconception #1: Students have different “learning styles.” -   Misconception #2: Humans use only 10 percent of their brains. -   Misconception #3: People are preferentially “right-brained” or “left-brained” in how they think. -   Misconception #4: Novices and experts think in all the same ways. -   Misconception #5: Cognitive development progresses in age-related stages.

having students work in groups for 30-45 minutes coming up with test questions that might be used (or reworded) in the actual exam. This is a two-fer, says Lang: it not only gives students a sense of control over their learning but also serves as an effective review session.

Open assessments – This involves leaving 10 percent of the syllabus for an assignment that students create with the instructor.

Class constitutions – Having students collectively come up with ground rules for a course gives them a collegial sense of working together toward a shared purpose.

“Teaching evolutionary theory is not in and of itself religious indoctrination.” That’s because evolution is not a religion. “How could a religion have no beliefs about the supernatural? No rituals? No moral commandments?”

ask students to learn about evolution without insisting that they believe it.

Students learn new ideas by linking them to what they already know.

“It turns out children are better able to cope if they understand what they’re going through is normal, that it affects everyone, and that it will pass,” comments Adam Gamoran of the William T. Grant Foundation. “How we think about a stressful situation influences how we feel and how we perform.” Studies like this, he says, “show how deeply intertwined are cognition and emotion.”

Connecting students to reputable, relevant scientific people and organizations in real time

Twitter as authentic audience – Students constantly tweet ideas, assignments, projects, suggestions, and photographs to each other, broadening the reach of their thinking.

Twitter as embedded literacy – Students get plenty of practice with succinct writing as they share analyses and observations.

Managing students’ encounters with objectionable material from the outside world, including occasional use of profanity and sexually suggestive follower requests.

Comparing services – Proportional reasoning, equations, creating and analyzing graphs, and number sense; -   Planning a budget – Organizing and representing information and number sense; -   Determining the costs and payoffs of higher education – Percentages, compound interest, and rates; -   Playing the Stock Market Game – Ratios, proportional reasoning, reading and analyzing reports and graphs, and algebraic thinking (e.g., gains and losses).

“The term generally refers to using a wide variety of hands-on activities (such as building, computer programming, and even sewing) to support academic learning and the development of a mindset that values playfulness and experimentation, growth and iteration, and collaboration and community. Typically, ‘making’ involves attempting to solve a particular problem, creating a physical or digital artifact, and sharing that product with a larger audience. Often, such work is guided by the notion that process is more important than results.”

Set up the environment so that students will be speaking and debating with each other in the roles of their historical characters and around a framing problem or issue

Bring in a variety of sources for students to analyze and research.

Social media is a wonderful connector for these kinds of simulations, with students setting up Edmodo, Schoology, or Facebook pages for their characters in a simulation, figuring out friend groups, posting photos, and speaking from their character's point of view.

But when kids see the horrific race-, religion-, and gender-based attacks committed in the real world by members of online extremist groups, they must wonder why adults can't stop these hate crimes.

Ultimately, hate speech is an area where sharing your own family's values -- around compassion and tolerance, appropriate communication, and empathy toward other -- sets a stable path forward for your kids to follow even in unsettled times.

How would you feel if you were a member of the group targeted by cruel language?

Does it matter if you're exposed to it a lot or a little? Are people with different social statuses -- for example, a popular kid vs. a loner type -- affected differently?

What's the difference between hate speech and cyberbullying? If someone is trying to hurt someone, or knows that they're hurting someone, and does it repeatedly, that's cyberbullying. When someone expresses vicious views about a group or toward an attribute of a group, that's hate speech.
