What’s the future of Twitter?

image

Twitter stock has recently suffered as a result of weak earnings (and related confidence), so I’ve been reflecting on the value I place in it versus Facebook.

Everyone’s surely different, but I figure one way for me to assess it is to evaluate the differences between the list of my Facebook friends and the accounts I follow on Twitter (I have to add my handle to my own list’s URL on Twitter, but of course with my “default” settings I can’t even share my Facebook list).

So what do I see? In my case, a rather subtle difference! Even before this comparison, I recognize that in my case I use these services in very similar ways—some close friends, some strangers—in short, a mixed social bag on both accounts. But by looking closely, the “game-ish” contours of Twitter start to emerge…

  • where word-smithing is more important… and fun (it’s such a chore on Facebook)
  • where I feel like I’m actively doling out social recognition by re-tweeting and favoriting (as opposed to the more personal Facebook “like”)
  • where I can easily search for new ideas (and break out of my filter bubble)
  • where I can blend my personal and professional interests (there just isn’t room for my professional self on Facebook
  • where my new ideas seems to matter more than my same old self

The indicators above seem like distinctly intellectual features that such a service could offer. In all other ways, Facebook and Twitter seem almost identical to me.

I recognize that this is a very particular case, and that there are many other ways to use these services. But, head-to-head, pound-for-pound, I also suspect that there is a deeper indication here that Twitter, even (or perhaps especially) when viewed as a redundant service, is of equal social value to Facebook in the emerging world.

Perhaps, even greater.

Designing Learning Futures

Here I am giving an Ignite-style talk two weeks ago at The Digital Media and Learning Conference in Long Beach, CA. It was my first time (both giving this style talk and attending the DML conference), and I really liked the format—20 slides auto-advancing every 15 seconds for 5 minutes. They’re supposed to be fun and thought-provoking, which was a good challenge in the context of a conference about “designing learning futures.” I tried gently poking fun at the audience by suggesting that we’ve all dreamed about being the person who, once and for all, creates a “Facebook-for-learning.”

The main point of the presentation was to think through how we’d go about building it—with a focus on development choices. Based on a simple rubric of what characteristics such a learning-centered application would have, I asked the audience to consider four diverse models of “social” apps (Facebook, Amazon, Moodle, and the SATs). I suggested the image of an Okapi neatly summarized the development conundrum, and concluded that such an application should be complementary to Facebook—not its replacement.

Well, there’s no guarentee my talk was substantial enough for the audience, but I enjoyed putting it together and delivering it. Several of the other speakers shared heartfelt, personal stories, and I couldn’t help feeling a bit upstaged. Deservedly so!

But the subtext of my talk—which I hope I sparked in at least a few of the couple hundred people in attendance—was to consider the necessity of developing niche applications for educational contexts. That is, it’s glorious that Facebook has a community of 600MM+ users, but it’s unlikely that learning communities will benefit much from being part of such a large-scale project. Sure, it would be great to preside over such a massive community as a software designer, and there are many feats that could be accomplished with data that it would throw off, but I’m skeptical it could serve learners more powerfully than smaller, more focused tools.

So, though I asked people to think about development issues, I hoped they walked away thinking about a learner’s “user experience.” I am cautiously optimistic that at least one person did so, as she tweeted:

“Facebook for learning. Okapi problem.”

Transmedia for Social Change

Today I attended the final day of an intensive workshop event hosted by Working Films. The event brought together a diverse group of talented filmmakers, powerful activists, and leaders in the education sector – I was lucky I got to crash their party! In their own words, it was:

a residential workshop designed to help filmmakers and non-profit organizations leverage the power of films that document some of the most significant problems – and innovative local solutions – that unfold every day in schools across the United States and the world… [The last day] is a day of serious strategy for groups already committed to advancing change in the educational sector!

Cool stuff. At the center of the event were seven amazing films (links below). After hearing from the production teams and seeing clips from their films, we workshopped “social action” strategy in small groups.

Social Action

Action. Justice. Change. Transformation. Learning. There was a lot of passion in the films, and a lot of potential to start conversations, dialogue, etc. So that’s where we started. It was a lot to take in: the filmmakers (and by extension the production companies) shared their visions of the kind of impact they wanted their films to have. Better educational opportunities? Yes. Empowerment for underserved groups? Yes. Social change? You bet. Some of their ideas overlapped, some diverged.

A theme from the ongoing discussion that stood out to me was what someone in the group referred to as a “transmedia strategy” – from the idea of transmedia storytelling across multiple platforms and formats (Kinder 1991, Jenkins 2003). The conversation that emerged throughout the day was how the filmmakers – if they wanted to enhance the transformative potential of their films – were likely going to leave the more familiar domain of film… and enter into meatspace and cyberspace in new ways.

Or, in other words, the essential question of the day was: How can films lead to action?

I think everyone was sympathetic to the idea that discussion isn’t enough – that talk is cheap, as they say, even with respect to democratic action. And there was a shared sense among the activists and the educators that the films could do even more.

Notes on Transmedia Strategy

So this was my schtick about trying to get things done online: Start by creating opportunities for “engagement” across a spectrum of actions ranging from simple to complex. (Twitter = simple. Facebook = pretty simple. Embedding video = getting harder. Coming to your site = not so simple. Using your tools = takes some dedication. Putting content on your site = hard.) The Internet may be somewhat indifferent to your ideology (so to speak), but it is definitely not indifferent to the design of your software/applications/etc. A strategy that includes many of these elements – and successfully engages your audience – is a sufficient transmedia strategy.

Across the seven projects (“projects” seems better than “films” in this context), there was already a variety of thinking about online and social action strategy. Interestingly, I sometimes couldn’t tell if an idea for an “app” or a website was a tie-in or a tool – and it occurs to me now that that’s probably a bad sign. Allow for a quick clarification of terms: for me, a tie-in is a filmworld thing (to bring people to the experience of the film), and a tool is an educational thing (that empowers people to change things). The two can go hand-in-hand – and I nodded my head positively as we talked about that – but it is an uneasy relationship.

I suspect it would pay off to disentangle a tool from other tie-ins. They’re different animals. A good example of this kind of distance is the “professional development experience for teachers.” That’s something that someone else builds, and inserts some excerpts from your film into. It’s not a tie-in as much as a tool. And: let someone else make that tool.

But, let’s say you want to build a tool for social change, and you want to do it yourself.

You want to build a way to help parents connect. A way to give young learners a voice. A way to make families without children care about education. A way to help people achieve a new literacy. (Let’s agree to ignore the teachers here on the premise that they got the professional development kit.) You’ve now taken off your filmmakers’ hat off and put on a crazy new hat. You’re building a new tool.

First of all, you still need the aforementioned transmedia strategy: that’s your so-called social media funneling people of all kinds toward your film experience. A tool isn’t that. And, perhaps sadly, it’s not your film either – that helps, but it’s a non-starter in an online/digital/phone/app space. It’s also not your festival-in-a-box (that’s a tie-in). If you want a great tool, don’t confuse amplification with transformation. Amplification is about getting the word out and the conversation started. Transformation is when you enable every person to make it their own.

Sidenote: let’s agree not to aim to change policy on day one. Not with the tool that you’re going to put online (or on a mobile device). Let’s be realistic here: it would be a huge win if your chosen constituency finds your tool as useful as a scrap of paper. You’ll have to build up from there.

So, secondly, and most importantly, you need to make a useful tool. A humble, easy-to-understand tool. One with a little inspiration and imagination. It’s just one part of your transmedia strategy. It’s the part that aims at a very specific group of people and allows them to engage or enact the ideas that are buried deep within your film. It’s a super simple thing that may spring into the world wholly-formed, or take shape through many stages of refinement and revision. Sure, it’s a tie-in, but it shouldn’t look like one. It has to be a gift.

So let’s get to the unpleasantries. Unpleasantry #1: If you want your film to be part of a tool, you have to give your media away for free. Yep: that’s how the Internet wants it. That’s how educators want it. That’s how students want it. You don’t have to give it all away. And this isn’t just a strategy to get people to come and pay for another experience. This is a reality. It’s a reality for films that are good, authentic, truthful, honest, and transformative. If that means your film, that’s probably a good thing. Get over it. Keep your day job. Etc.

Unpleasantry #2: Developing good tools is hard. It’s easy to throw a lot of money at the problem and lose. But that doesn’t mean it’s expensive. You just need new friends. These new friends will be young, opinionated, difficult to communicate with, and just generally strange by your standards. (That’s okay though, right? You’re a filmmaker for goodness’ sake.) The words they should be saying to you are: simpleiterative, open source. That’s not a recipe; it’s just a good foundation. If they’re not saying those things, good luck to you. I have no idea what you’re building.

Unpleasantry #3: You need data. You need to convince your new aforementioned friend(s) that you need data. Each and every new aforementioned friend will not like the idea of gathering data, but with a little push, he or she can create a nice foundation. Traffic? Sure. An understanding of how individuals use your tool? Excellent. Demographic data? That would be nice. It’s unclear what you’ll do with it now, but it’s for the future. It’s for growing. It’s for understanding what you’re actually doing. Collect it. Organize it. Save it. If your tool is successful, it’s going to help you tell your story. Data is the cinematography of the digital world. (Hypothesis for further exploration: collecting great data is the high art of social change.)

Bonus round: give your users control over their content and their data. This will ingratiate you to the geeks and the media literate, but it’s also a great practice that will help you build a community around your tool. Give them an easy way to give you feedback, too.

Lastly, importantly,

I hope this vaguely coherent rant is more clarifying than it is discouraging. There is a ton of room in this world for transmedia for social change. We’re giving up too much if we leave it all up to Facebook, Google, and Apple. Jump in and play a bit. Hey, you’ve made a film… do you really want to do that again anytime soon?

Also, don’t forget about the people in your films. They are the people who have been given the most powerful tool of all.

Lastly, a big thanks to the multitalented organizers of the workshop, and, of course, anyone who had to suffer through an encounter with me, lol.

The films:

Programming as a New Literacy

I’ve just read Douglas Rushkoff’s shortbook Program or Be Programmed, wherein he shares “Ten Commands for a Digital Age.” Though his portrayal of various “biases” of digital technology (e.g., timelessness, abstraction, depersonalization) is polemical, he succinctly describes major challenges of new technologies in 144 pages.

His main point is to describe a new literacy – a digital literacy he says we must achieve to continue to shape our world in positive ways. He argues that the consequence of not being able to “program” (or, he allows, at least being familiar with the scope and power of programming) would be to allow digital technology – and those who wield its powers – to overdetermine our lives.

I am sympathetic to this message, but reading his argument served as a good exercise to review the larger picture – and consider how well this kind of story about “digital literacy” hangs together.

One area Rushkoff’s book helped me reflect on was the design of online learning environments. In line with his descriptions of digital biases, current learning management systems are often positively shaped around the “advantages” of digital technologies. Asynchronous discussion boards are favored. Students are asked to use their real identities. There is “space” for collaboration.

So far, so good. But Rushkoff helps us ask: what about the “speed” of dialogue and collaboration? It seems to me that instructional designers (teachers or their assistants) could make the mistake of hoping that student interactions (with the course, and with other students) only increase. Or, similarly, that the administrative evaluators of such courses favor more frequent interactions.

As Rushkoff points out, such desires could be our ill-considered adoption of digital biases, and in fact, slower, less-frequent interactions could be preferable. While he harkens back to the “early days” of online bulletin boards, and points to the “depth” of discussion that came out of less frequent “logging in and signing on” (p. 24), I think it could more simply be a case of “less is more” – that writing and editing take time, and focus can help one achieve better communication. I wonder, therefore, how we could sharpen the design of online discussions to favor more reflective engagement.

There are already great examples of this online. From the way sites like the New York Times aggregates Comments, to the way tools like Disqus track one’s diverse contributions, there is a lot of good thinking about shaping online discussion. How could educational designers incorporate these and other strategies into a “course” experience?

Changing Teaching with Learning.com

Are teachers emerging as DJs?

“You are innovators” is the message to the teachers at Learning.com‘s second annual professional development workshop in Portland, Oregon. I’m attending the workshop to learn more about their really interesting new software, Sky. I’m also interested to learn if their message to teachers is accurate, a wishful prediction, a hyperbolic marketing strategy, or something else. Working alongside teachers who are learning to use Sky, I begin to hope, will lead me to an answer.

Sky is the name of Learning.com’s recently-launched digital learning environment – which means, among other things, that it’s a platform for teachers and students to access instructional modules (what used to be called curriculum). Using Sky, teachers can create and assign modules (games, animations, links to online resources) to individual students, groups, or a whole class. Each student can go at their own pace or skip around, leaving a trail of data about their learning experiences.

Seeing a group of 50 teachers, librarians, administrators, and other educators learning to use this tool brought to mind a salient issue looming over the education sector: the transformation of the work of teaching from a classroom-based activity to a community-based activity. By this I mean to suggest that the horizon of a teacher’s work is expanding in two senses –  both spatially (i.e., a teacher can interact with people in a distant location in a way that is perhaps easier than stepping out of the classroom and walking down the hallway to speak to a colleague) and socially (i.e., a teacher expected to interact with more people than ever).

To anyone who’s interested in education these days, this is not exactly new news. But watching teachers learn to use Sky, a metaphor floated into mind: teachers are being asked to abandon their role as performers. Software like Sky demands that teachers become increasingly like DJs. In short,

Teachers are being asked to jockey media (of all kinds) in the way that DJs jockey music.

Consider this description of a “Club DJ”:

Club DJs are very well versed in mixing music to motivate the club goers to dance and drink. Very successful Club DJs can amass real fan followings. Club DJs have historically been on the leading edge innovation when it comes to leveraging the equipment they have for the best new sounds and memorable effects.

Putting aside the goal of dancing and drinking for the moment, the part of this description that strikes me as apt is the effect DJs have on their audience: they are recognized for leveraging the equipment they have for the best new sounds and memorable effects. As companies like Learning.com put innovative software into teachers’ hands, and when these tools further extend the reach of teachers to more and more content (note: I am using “content” and “media” interchangeably, where media puts the emphasis on the diversity of available content), it seems that their role as purveyors of knowledge – and, therefore, as critics and curators of media – is made more pronounced.

Great teaching has, of course, always been about being knowledgeable about, and delivering, content (with bonus points for delivering the right content at the right time). But a significant change that software can make possible is the amount of media that a teacher has access to, and therefore, has the possibility of being knowledgeable about. And this goes beyond mere facts and static content – even beyond dynamic content, methodology, and analysis –  and into the area of the learning tools that students can use in conjunction with that content and those processes.

So what are some of the new tricks that Teacher-DJs will have to learn, refine, and become known for? The following come to mind:

  • delivering simple, efficient, and multi-modal learning activities to students
  • directing students to great, fresh, and relevant resources
  • providing a directed (but not inauthentic) way to experience the Internet
  • sharing responsiblity for student work (and related actions) on school-suported publishing platforms

A related way these changes will likely play out is that authorship will increasingly become an important aspect of teaching. Whether a teacher is authoring content for students, describing and/or reviewing content for fellow teachers, or describing and/or reviewing content for a wider audience (including parents, administrators, and communities), the immediacy (and sheer reach) of the Internet will amplify the importance and potential of this work.

For example, Learning.com has ventured into the realm of positioning teachers within a network powered by sophisticated social software. Using Sky, teachers can create and share lesson plans – lesson plans they may have always had, but perhaps never before in a form that was so ready for sharing so widely. Software features that support searching for, selecting, and rating others’ lesson plans raise the significance of formerly merely digital tools (e.g., putting lesson plans online) to a new level.

An interesting effect of this kind of social software will be that there may be (will be?) increasingly more social pressure on teachers to create and share their work with other teachers. So teachers will be authors not only in the sense that students will use their multimedia assemblages (which seems like a good way to describe their products in software like Sky), but in the sense that other teachers will be able to access their work. By sharing work in this way, and as a community of teachers becomes interested in the depth and quality of a fellow teacher’s work, each teacher may subsequently be judged by it. And though this may have been the case previously on a more local level (e.g., interactions between a teacher and his/her department or administrators), social software is fundamentally changing the professional landscape of teaching by transforming social interactions between teachers.

Understood in this way, it seems that social software is becoming intertwined in what some consider the history of the de-professionalization of teaching. Though, as we see in the comparison to the work of DJs, it is also creating new possibilities of professionalism through a kind of grassroots process – where the day to day work of teachers (lesson-planning) becomes a new kind of lingua franca in valuing a teacher’s abilities and achievements. This is promising stuff. But where there can be little doubt that software like Sky will change teaching, how long it will take for the policies and realities that regulate the day to day activities of students under the watch of lumbering bureaucracies is less clear. And so,

It is still unclear if social software can be a vehicle that gives teachers more power to directly transform the education sector.

Looking into the heart of software like Sky, one sees how teachers are being asked to change the way they work in both obvious and subtle ways. Making a comparison to the work of DJs is, after all, probably not fair. But I think it’s a helpful metaphor. DJs take a lot of pride in their work, and are recognized for their unique contributions to spaces, events, and communities. Rather than evaluating a cultural shift in teaching as a good or bad thing, this kind of lens helps me better understand the kind of work teachers are being asked to do.

Are teachers innovators? Software like Sky gives them an opportunity to innovate. Not all will, but those who do will participate in an interesting transformation – and potentially a watershed period – in the history of the education sector.

Taking responsibility for the impact of software

Here’s Steve Jobs, from a recent email thread with Gawker’s Ryan Tate:

Do you create anything, or just criticize others (sic) work and belittle their motivations?

This last missive from Job’s is a nice rejoinder from a back-and-forth with Tate about Apple’s iPad platform (and related technologies). And if you don’t look too closely, you might be impressed by it.

By now it’s well-known that Apple draws the ire of the free software community. But Steve Jobs take the time (here in a private email conversation) to clearly articulate his views and motivations. Really? A CEO taking the time to pursue an email flame war with a spiteful blogger? Very respectable. Admirable, even.

That’s what it seems to take these days to engage the public, especially in the software development space. And I like Jobs’ response and his insistence on participation: he asks (I paraphrase), “Are you at least engaged in similar work?”

But wait, is that enough? Tate started the email thread by criticizing Jobs’ abuse of the language of “revolutions.” Does Jobs offer an adequate defense?

Jobs’ response is related to a too-easy dismissal: “If you don’t do X, you can’t criticize it.” But I don’t think that’s Jobs’ attitude in this case. Tate’s criticism against Apple is steeped in deep knowledge of the software world. I think Jobs’ is asking for empathy, saying (again I paraphrase), “It’s hard to bring these new technologies into the world, isn’t your quibble with us a minor one? Why can’t this discussion be more civil?” Or even, “It’s a mistake to equate what we’re doing here with something important.”

But then that’s why Tate is right and Jobs is, ultimately, a corporate ass: Jobs isn’t taking personal responsibility for his company’s ridiculous (“it’s magical” and “it’s revolutionary”) claims. Jobs’ insistence on deflating the significance of the iPad’s implications for the software community flies in the face of Apple’s language describing it. Once you say it’s revolutionary, there’s no going back and saying that you didn’t mean “in a cultural or political way” (Jobs’: “It’s not about freedom”).

So, frankly, this exchange turns out to be as offensive as it is instructive. I’m glad Tate shared it. Sure, we can empathize with Jobs… it is tough making great things. Especially complex things. But the work of understanding them – seeing their implications, assessing their value, and measuring their impact – is a shared responsibility between both developers and consumers. Indeed, it’s part of the cost of doing business, though easy to forget.

So, how can a development group take responsibility?

  • Do an impact study and publish it
  • Build assessment into your development process
  • Perform ongoing data analysis and research, and share it
  • And, of course, talk openly with your customers (at least Jobs got that one right!)… with luck, they’ll engage you in a fruitful conversation about culture, politics, and the future.

The new low cost of exchanging knowledge

David Dean, founder of Yamisee, gave a great talk about this new, e-learning tool at a EdLab today:

Yamisee is a live online learning platform that creates an entirely new marketplace for teachers and subject matter experts to share their knowledge. Much in the way eBay connects buyers with sellers, Yamisee connects independent experts with paying students. Providing everything an instructor needs to conduct classes and earn money through live online learning events is why Yamisee was selected as a 2009 Company to Watch by the Connecticut Technology Council. (from the event description)

David discussed how they are striving to make Yamisee a marketplace of learning opportunities, and it seems like he has the basic structure to make it a vibrant one.

Why it might catch on:

Why it might not:

  • The marketplace is ultimately built on trust – bad options and high standards could hurt the business model.
  • People may not care as much about social interaction as we might think (they may prefer to crawl the web instead).

But both of these are more business-related worries than technical or conceptual problems. Overall, I’d be excited to see a social network like Yamisee be successful, because that would mean people are excited to learn new things from experts. (And that’s not always the way things seem to go these days…) It will also be interesting to see if this kind of e-learning tool is able to distinguish itself from the growing list of options.

Thanks David!

Building a better institutional archive

“How do you make an institutional archive more social?”

This question was put forth by EdLab in early 2006. It’s kind of a strange question – it makes more sense if you consider how “Web 2.0” had settled in as a useful framework in our collective imagination. We faced the task of creating a digital repository for the first time at Teachers College, and we wanted to do it with style.

We created PocketKnowledge (PK), and launched it later that fall to the College community. Phil the Pocket was born. In theory, PK did everything DSpace did, but better. The community could upload and tag items. A folksonomy could emerge. Uploaders could set different permission levels to control access to their content. And so on. From the project documentation:

[We] formed a multi-disciplinary team of students, designers, software developers and institutional representatives to implement a digital archiving solution for Teachers College, Columbia University. After an analysis of existing archiving tools, our interests pushed us in the direction of developing a custom tool to serve a set of functions that was not possible with existing archiving tools, but which we determined was possible with available technologies.

Existing digital archiving software – such as the widely implemented DSpace – did not offer a “social” solution for arching. DSpace employs “gatekeepers” who oversee the uploading of new material into the archive – often librarians who grant permission to upload materials, organize the materials into established categories, and tag the material with standard keywords.

PK was designed to overturn this librarian-centric model, and put power (and responsibility) in the hands of content creators. It is different from DSpace in many ways, and is successfully social to a discerning eye.

Was PK social enough? Probably not. And the definition of “social” has only steepened in the past four years. Here is a shortlist of ideas about how it could be more social that I’ve been able to collect:

  • Tag any document on the fly (currently only content owners and admins can do this)
  • Curate new collections of items (currently only content owners and admins can do this)
  • Create a personal “profile” page with favorite PK items
  • See “popular related” items for any item
  • Simple versioning control for items (to better facilitate group work)
  • Available email updates when users interact with items and collections

I wonder what ideas others might have now. And, should we continue down this path at all? Is it time to give up on the idea of a social archive? After all, we’re social in many ways… why should my archival materials extend my range of social interactions further? (And aren’t there already better methods for this?)

In spite of these worries and concerns, I think it is still a seductive opportunity. The best answer to the question may be a relatively simple one:

“Give me an extremely lightweight publishing opportunity that supports and is supported by (and is partially obscured by) an educational institution to which I have accepted as a platform and community for intellectual work.”

Institutional collaboration as strategy

Brad Wheeler says that higher ed is a “different” kind of industry in that institutions don’t directly complete against each other. Instead, and as a consequence, ed organizations should follow a strategy to approach problems in similar ways (across a wide range of activities).

He spoke about the growing set of activities that are leading to a “meta-university.” Parts of this tool-set, he says, come from the following inter-institutional collaborations that have resulted in the following software projects/platforms:

He also talked about the foundation for joining collaborative development across institutions. Some key factors:

  • Goal alignment
  • Values alignment
  • Temporal alignment
  • Talent alignment
  • Governance clarity
  • Problem solving alignment

So, to summarize, it sounds a bit impossible to join one of these efforts. On the other hand, I would love to see PocketKnowledge develop in a direction that brings in external collaborators (even leaders!). To that end, he mentions several of the “many ways” individuals and organizations can collaborate beyond contributing code, such as…

  • commenting
  • testing
  • critiquing
  • creating buzz

An interesting model for PocketKnowledge might be what he calls “Institutional Sourcing” (as opposed to “Commercial Sourcing” or “Consortium Sourcing”)… where an institution’s reputation drives its roll as leader and manager of a particular tool.

The textbook for hip introductions

I found Shmoop recently, which is a site that lures young learners with the promise of short, “hip” introductions to everything a student needs to know. It’s a funny site that seems like it’s meant to be a somewhat encyclopedic review of all the topics that might be in a standard curriculum (it calls itself an early beta). So how much better than Wikipedia could it be?

Well, check out the copy, and you’ll find an editorial voice with “young people” in mind. I guess this may be desirable/useful. Time will tell. I wonder how much effort it will take to keep this up to date over time.

I think it’s a good example of a curriculum-like resource being market towards “professional” students. But as a would-be Wikipedia, it’s part of what I’ve been calling the parallel world problem. For that reason, I think Shmoop will be an interesting case to keep an eye on as networked resources continue to replace textbooks.
