In July/August 2006, ASTC Dimensions examined new social technologies—blogs, podcasts, wikis, RSS feeds, and other “Web 2.0″ communication tools that allow Internet users to personalize their online experiences. That was then; this is now. Moving past MySpace, Facebook, and YouTube, the buzz today is about immersive digital experiences, mixed realities, avatars, and the 3-D Web. Researchers document the benefits of video gaming and design “serious” games to support educational or therapeutic ends. In the multi-user online world Second Life, your custom-designed alter ego can visit a museum, take a class, view a webcast, or interview for a job. Seniors can’t get enough of digital brain games, second graders play Zoo Tycoon, and Nintendo’s whole-body Wii gaming console flies off the shelves. How does all of this relate to learning in science centers? In this issue, we’ll explore the new digital immersive technologies and learn how museums are using them to create experiences for the tech-savvy audiences of the 21st century.

Museums are already using 3-D visualization, animation, and even single-user virtual worlds in their real-world exhibits and programming. Why then go to the trouble of creating multi-user, online virtual spaces? Is there something about these social 3-D spaces that enables online visitors to experience science exhibits differently than via 2-D web sites and interactives?

Designing for multi-user-enabled web sites requires consideration of real-time interpersonal communication. In the context of current Internet methods, this could be user-created personas/identities, chat, messaging, videoconferencing, and/or games. And even if you don’t attempt to create games or game-like experiences online, you will need to think about online content and exhibit design in the context of how multiple visitors might experience those things together.

Despite those concerns, and others related to costs and technical requirements, many museum professionals feel a need to create a more social Internet and to widen their online exhibit aesthetic to include more of this element. Multi-user 3-D virtual worlds allow “face to face” interaction between web users around the world, in spaces that are representational, abstract, or completely imaginary. They also offer a way for museums to stay in touch with community members and casual audiences and to design and present content that’s relevant for and interesting to those audiences in a personal way.

Predating Web 2.0, most 3-D virtual worlds have, at the core of their user-experience design possibilities, built-in tools and methods for collaboration and user-created content. As a developer of content and experiences in virtual worlds, you will need to think about balancing the elements of 3-D interaction, real-time communication, and user-created content. Each of these elements is familiar and powerful by itself. By bringing them together, and by designing content and experiences that leverage how they work together, you can create personalized and social experiences and learning opportunities for your online visitors.

At the Exploratorium, media creators and educators have been experimenting in Second Life (SL), a rapidly growing (9 million+ registrants to date), massively multi-user, 3-D virtual world and online community. This unique space is not a game, but an open-ended environment where all the content is created by the members of the community, or “residents.” (Note: To access the secondlife:// URLs referenced in this article, you must have the SL client software installed on your computer.)

SL makes experiences of the 3-D Web accessible not only to content creators, but also to a web-savvy public. In SL, users navigate their “avatars” (virtual-world characters) through the world’s virtual landscape. Through a spatialized audio system, SL residents can now speak to one another using microphones connected to their computers. This mix of real-world and virtual-world realities allows participants to further personalize their experience.

Moving into Second Life
On March 29, 2006, the Exploratorium presented a live webcast covering a total eclipse of the sun as viewed from Side, Turkey. Telescopic views of this rare sun/moon/earth alignment, created in collaboration with NASA’s Sun-Earth Connection Education Forum, were broadcast with scientific commentary via satellite, television, and Internet streaming to hundreds of thousands of viewers worldwide. We also created an overnight program at our museum in San Francisco where the public came to view the live eclipse webcast.

This event seemed a perfect opportunity to try our first venture in Second Life. We streamed the program into several locations in SL and created a companion set of in-world exhibits. The combination of live streaming video, a unique viewing environment, interactive exhibits, and in-world hosts to answer questions provided a virtual-world experience that mirrored our real-world museum programming. The 65 SL residents who attended remained actively engaged throughout the one-hour presentation. This showed us that a live webcast-viewing experience in-world could attract and engage SL visitors.

Our next SL undertaking was to create the ’Splo, an industrial-looking space in an in-world urban setting filled with more than 100 3-D exhibits (secondlife://Midnight City/ 176/58/26). Some of these exhibits were new to the Web; many would be hard to make in a real-world museum.

Encouraged by positive visitor experiences at the ’Splo, as well as by the response to the eclipse event, we were inspired to establish a larger SL presence for the Exploratorium and develop relationships with other educational content creators working in-world. We have since built an entire island called Sploland (secondlife://Sploland/ 175/75/25), filled with both serious and humorous exhibits, and have hosted two more live SL events.

The first of these, in November 2006, was an astronomy presentation offered in conjunction with the National Optical Astronomy Observatory (NOAO) at Kitt Peak, Arizona. We offered a live streaming webcast of telescopic views of the transit of Mercury as it crossed the face of the sun. In SL, the event was hosted at the International Spaceflight Museum (secondlife: //Spaceport Alpha/48/78/24/) by ’Splo avatar-scientist Patio Plasma (an Exploratorium physicist and educator in real life), who demonstrated the phenomena using an interactive, 3-D planetary-orbit model.

We also presented a Pi Day event on March 14, 2006, jointly celebrating Einstein’s birthday and the number pi (3.14). In the real world, the Exploratorium has hosted Pi Day events for more than a decade. This year, staff built dozens of Pi Day exhibits specifically for SL, including PiHenge (like Stonehenge, but with pi-lithons replacing trilithons) and a giant Pi sculpture that spit out cherry pies. Avatars could try “hands-on” activities, such as building a Pi glass, a cylindrical drinking glass as tall as its circumference. Exploratorium visitors could watch the SL goings-on in our real-world theater and ask questions about the virtual world, and Pi Day events at the museum were streamed into SL, where avatars could query staff avatars about them. In San Francisco, visitors were served slices of pizza and dessert pies; in Second Life, avatars received free Pi Day T-shirts.

Most recently, we have launched Exploratorium Island (secondlife:// Exploratorium/163/124/23), a multipurpose space where we plan to build and prototype exhibits, present public programs, and offer workshops from our teacher-education programs. Exploratorium Island and Sploland are part of a group of science-technology-themed SL locations called SciLands (http://scilands.wordpress.com), a sprawling campus where avatars can stroll (or fly!) around and engage in experiences across a range of topics. SciLands includes both real and virtual institutions; it has a governing board to oversee the addition of new content areas.

What you can do in SL
So what kinds of online exhibits can a virtual-world science center offer that visitors can’t get in real life? Here are a few ideas we’ve tried with success.

1. Move the visitor around
In the real-world Exploratorium, there’s an exhibit where visitors walk up to an upside-down photo of TV personality Vanna White. At first, there doesn’t seem to be anything wrong with Vanna, but when you rotate her photo, you see that her eyes and mouth have been cut out and placed upside-down in her otherwise right-side-up face. The effect is grotesque and disturbing. The exhibit shows that people analyze pictures of faces in pieces, looking at the eyes and mouth independently. In our SL museum, we’ve made two copies of the exhibit. In one, the viewer rotates the photograph as in the real world; in the other, the avatar gets rotated instead—a memorable experience for SL residents.

Another exhibit allows avatars to either watch the orbit of Comet Halley, or ride the comet as it races away from the sun, slows near aphelion, and finally plunges back toward the sun. Most choose to ride the comet.

2. Change the scale of objects
Unlike in the real world, it’s easy to change the scale of natural phenomena in the virtual world. For example, to help visitors understand eclipses, we built a scale model of the earth/moon system in SL. We hung an earth model in space (easier to do in a virtual world!) and, at the same scale, hung a moon model 30 meters (100 feet) away. People visiting the exhibit, including real-world astronomers, have noted that they had no true appreciation of Earth’s scale relative to the moon before encountering this exhibit.A virtual world can also offer access to the very small: One inspired SL resident built a model of the Brownian motion phenomenon, which describes the random motion of particles. In his model, four cubes that would be a few nanometers across in the real world tumble and spin inside a transparent cube 10 meters on a side. Taking advantage of what we’d learned about a virtual visitor’s scale-of-reference experience, we suggested allowing avatars to ride the cubes. The view from a particle undergoing Brownian motion and rotation in 3-D makes for a wild ride.

3. Make exhibit information portable
Museums in the real world often struggle with how to present interpretive materials with their exhibits. Too much information for one visitor might not be enough for another. In a virtual museum, you can create rich textures offering visual or textual information adjacent to or on exhibits, or you can attach “notecards” that avatars can read and discard or save in an “Inventory” file. Notecards can be linked to other notecards or to web pages, offering deeper levels of detail, examples, references, or links to real-world museums.Both notecards and objects can have scripts attached that offer mementos or artifacts. You can give a visiting avatar a talking book or a T-shirt or hat customized with museum graphics. The ability to integrate textual and other external web content into the virtual experience is an active area of development for Linden Labs, creators of SL.

4. Let visitors experience dangerous situations, or take them to remote locations.
It can be tricky to explore the inside of a nuclear reactor core in real life, but avatars in Second Life need have no fear flying around inside a 3-D model of a working nuclear reactor. Bringing live audio and video from expeditions into SL simulations offers a unique way to engage visitors and connect them to activities at inaccessible locations.

Exhibits and social interaction
Visitors to virtual-world museums are more than just usernames; they’re “residents” who can express an identity and demonstrate interest in a museum’s ideas and exhibits. Through design, voice, chat, and gesture, this persistence of identity and level of expressiveness allows both museum staff and visitors to make important social connections that, for many, are not as easily made or maintained on the 2-D Web.

Because virtual-world audiences typically enjoy interacting with one another, public programs that offer shared experiences add an important dimension that can increase your level of contact with the SL community. And watching residents interact with your content in real time opens an opportunity to prototype exhibits and spaces and get important feedback about use patterns and good design. Although audience numbers in virtual worlds are not yet as large as those on big web sites, the time that individuals spend with in-world content can be significant. Visitors to the ’Splo, currently about 200 per week, spend a lot of time viewing and playing with exhibits—more if they visit with other avatars, a trend we plan to study.We’ve found that ongoing interaction with other residents—including other museums and educators—is important to staying in touch with the community and keeping content and programming relevant. New members can take advantage of guilds, groups, and communities of interest already organized in SL, or start their own. In addition, designing exhibits and programs that allow tech-savvy content makers to build things, share images and video, or make machinima (movies created entirely in virtual worlds; see http://en.wikipedia.org/wiki/Machinima) can keep visitors returning to your space.

The IMLS-funded VolTS (Volunteers TryScience) project described in the September/October 2007 issue of ASTC Dimensions is a recent U.S. effort aimed at helping ASTC members forge better relationships with practicing scientists and engineers. But collaborations among content experts and museum educators are nothing new. Such partnerships date back to the founding of the field and continue to strengthen our institutions. Whether as museum volunteers or as partners in grant-funded projects, scientists and engineers welcome the chance to tell the public about their work and contribute to the goal of a “science-literate” society. In this issue, we share some examples of successful projects and examine the factors that make for success (or challenges) when two cultures—research science and informal science education—meet.

From ASTC Dimensions, September/October 2007

In November and December 2005, Randi Korn & Associates Inc. (RK&A) conducted a front-end study for the Volunteers TryScience (VolTS) project (see sidebar at end). The evaluators conducted and analyzed 26 in-depth telephone interviews with members of three groups:
• scientists and engineers who volunteer in educational programs outside of science centers
• scientists and engineers who currently volunteer in science centers
• science center staff who work with volunteers.

The volunteers came from both academic and corporate backgrounds; some were retired from full-time employment. Discussion groups were also held with science and engineering professionals who attended a 2006 IEEE conference; these findings, though not presented officially in the RK&A report, did inform the analysis and recommendations.

This article is based primarily on the interviews done with the volunteers and staff who work in science centers. Museums were picked by location, size, and range of volunteer opportunities they offer. The kinds of collaborations represented ranged from advisory panels to one-time lectures to exhibition development. From the observations and recommendations in these interviews emerges a summary portrait of the characteristics that make for a healthy partnership.

Attitudes and motivation

Why would busy scientists and engineers take time out to share their expertise with science center audiences? Most volunteers we interviewed had only positive things to say about informal science education. They praised the inquiry approach of science centers and their outreach to general audiences:
“The value is in the hands-on nature….”
“Science centers do a good job of just giving people access.”
“I know that they have a commitment to the community, so I was happy to get involved when they asked.”

Volunteers expressed a desire to “give back” to the community, but they also saw their role in the museum in specific terms. Some had come to the museum to share their expertise in a certain area of science:
“They asked me to be the champion for that volunteer activity.”
“My role was basically in an advisory capacity, for the science end of things.”

Others saw an opportunity to educate the public about what scientists do:
“I think people think of engineers and scientists as boring; the science center helps the public interact with people doing the jobs.”
“It is all about networking; You’re meeting people and getting to talk about your passion.”

Even for those who, like one NSF-funded researcher, came because their particular project required community outreach, the social element was an important factor:
“Otherwise, I don’t have the opportunity to talk to people about my work outside of work.”
“It made me realize how good it was for me, from a job perspective, to talk to the people you’re trying to serve.”

Interviews with volunteer coordinators revealed that they value equally the role that these expert volunteers play in the science center. “They are able to make real-life science connections,” said one staff member. Said another, “It is extremely important to … show that we are in contact with people doing real work, real research, right now.” In general, museum staff value in their scientist/engineer volunteers what one coordinator called their “instinctively higher regard for and understanding of science and the science process.”

Recruitment

Scientists often have difficulty finding volunteer opportunities aligned with their interests and expertise, tending to rely on word-of-mouth or personal connections. Some suggested that recruiting efforts should come from the top, be explicitly supported by the top, and be addressed to the top:
“You have to have people on the same level talking.”
“Let them meet and talk with the director. Let them know that they’re being invited to be part of a collaborative team.”

Others recommended going through existing channels, such as corporations, graduate-degree programs, or professional societies:
“You’ve got to get people to start volunteering by the time they’re grad students. Make it part of their education.”
“Go speak to the engineering society meetings. African-American graduate fraternities and sororities are typically active in large cities.”

Almost all of the scientists/engineers we interviewed are employed either full- or part-time. With little time to spare, they value clarity about their role in the science center:
“How many hours, what are my interactions, what am I going to get, what do you need from me? Scientists love it if you spell it out…. Then they can actually use it in the grant-writing process, in their annual reports.”
“I need to know exactly what’s expected of me. If [the museum representative] can say, ‘This is the commitment I want; this is your role,’ then the scientist can say, ‘I can do this’ or ‘No, I can’t.’”

Volunteer coordinators identified as major recruiting challenges a lack of funding (“Publicity and marketing … is staff-intensive work.”) and turnover in personnel at partnering companies and universities (“I may have a contact from one year who may not be the same person the next year”).

Like scientists, museum staff saw partnerships with graduate students and postdocs as a promising direction: “There is some leverage that could be gained from giving young scientists in training more interest and skills in communicating more broadly…. We would be moving toward the larger goal of having a more science-literate society.”

Training

Interviews with scientists and engineers revealed a general level of resistance to formal training by museum staff and a lack of interest in direct interaction with museum visitors:
“First of all, [we] don’t believe in training. Scientists have never heard the words ‘professional development.’ Personally as a scientist, I don’t know what that means.”
“Being a scientist, I wanted to just deal with the science…. There was just so much other stuff that went along with it. I wanted to help them deal with the science, interpret the science—nothing more, nothing less.”

Museum staff are aware of these attitudes. “Certain scientists and engineers are great with people,” said one coordinator, “and certain ones are not. What we take advantage of is their interest level … and desire to share knowledge.” Another acknowledged that “there is a perception that we cannot ask them to commit to many hours of training.”
Some scientists admitted they need help in approaching new audiences. “It’s easy to … make assumptions that are invalid simply because you’re not used to speaking to such an audience,” one confessed. “That’s a challenge the museum can help you meet.” But instead of classroom-based training, several suggested a partnering relationship, in which the volunteer would contribute knowledge and passion about content, and the staff person would contribute knowledge about museum practice.

This idea makes sense to museum personnel, too. Some favor “face-to-face” training for scientists and staff on how to collaborate successfully; one wished for an online “repository of great exhibits … or case studies [to show] potential volunteers about successful experiences.” Unlike the volunteers, some staff members expressed a desire for related professional development, particularly in keeping up with science research and best practices.

As with recruiting, finding the time and resources to manage volunteers is a challenge for museum staff, “not so much because of the volunteers but because of the work load and how thin we are spread right now.” As one coordinator said, “Staff do not necessarily have the time to get to know them [the scientists] the way we do with our regular volunteers.”

Nurturing the relationship

Most of the collaborations involving study participants were time-limited. Short-term projects appeal to volunteer scientists because they are manageable and to coordinators because they provide a positive initial exposure to museum culture.

But even more rewarding, some said, are relationships that are sustained and long-term—the kind that become, as one coordinator put it, “necessary to daily operations.” To achieve that goal, mutual understanding and respect are essential. “There are some cultural barriers between museums and scientists, but I think these can be breached,” said a volunteer. “You have to know how to interact with each other.”

One thing on which most agree is the importance of recognition, regardless of the scope of the activity. One scientist said, “It’s the little things that let people know they’re valued…. Once an exhibit is up, bring us in and show it to us. Put our names on a plaque. It’s just a nice gesture.” Another stressed the significance of feedback: “It’s important to have some sense of accomplishment, some evidence….
I’m a scientist. [We like] to know that what we’re doing with our free time matters.”

For staff, appreciation consists not only in providing appropriately challenging work and recognition, but also in demonstrating a commitment to ongoing relationship. “Our volunteer program has a full-time manager, a volunteer association, formal events … all signifying that [they] are a serious business to us,” said one coordinator. “The most important thing for me,” said another, “is to … get buy-in from the volunteer. It is important that the volunteer see what the science center is doing, and what its purpose is, to give them that ownership.”

Formerly a senior research associate at Randi Korn & Associates Inc., Alexandria, Virginia, Renee Miller recently accepted a position as an elementary and middle school science teacher at the Langley School, McLean, Virginia.
Volunteers TryScience: A Fresh Look at a Longstanding Relationship

Scientists and engineers have participated actively in science centers for decades. But many of these partnerships have occurred in isolation, with little chance for others to learn from their example. Even within a given organization, there may be roadblocks to learning from experiences with content experts.

VolunteersTry Science (VolTS) is a partnership among the New York Hall of Science, IBM, ASTC, the Institute of Electrical Engineers (IEEE), and the National Science Digital Library (NSDL) that seeks to facilitate more involvement of scientist and engineer volunteers with informal science education institutions through better communication, training, and resources. Funded in 2005 by the Institute for Museum and Library Services, VolTS represents an opportunity to share stories of exemplary accomplishments and ongoing projects and to initiate a broader conversation, from the perspective of both sides, about effective ways to manage those relationships.

Researchers who study the human brain and nervous system continue to find connections between environmental sound (both ambient and organized) and behavioral and emotional response. Anthropologists and neuroscientists alike tell us that music has been and remains critical to the development and survival of our species. It seems that people are hard-wired to respond to the quality of sound around us. Yet the auditory environments of science centers do not always reflect that understanding. The July/August 2007 issue of ASTC Dimensions draws on research into acoustics, the brain, and learning, as well as current museum practice, to explore the effect of sound on human experience—with implications for the design of both exhibits and the larger museum environment.
