Although it’s not the world’s deepest, widest, or longest canyon, there is something about the grandeur of Grand Canyon that strikes awe into those who view it and makes them more open to new connections with the Earth and its landscapes. Five million annual visitors, many of whom don’t think they are interested in science or geology, start to ponder questions about Earth’s history when they are confronted with Grand Canyon. They wonder, “How did something the size of the Colorado River (way down at the canyon’s bottom) carve a 10-mile-wide and one-mile-deep canyon?” and “How long did it take Grand Canyon to form?” Innate curiosity about the dynamic processes and history of Earth seems to be rekindled for people of all ages and backgrounds by the place itself.

Fifteen years in the making, the recently opened Trail of Time geoscience exhibition helps visitors frame some of their questions. The exhibition tries to convey and foster a sense of passion for Grand Canyon geology, and a sense that the future of our species will likely hinge on how well humans understand, coexist with, and utilize Earth systems. One of Grand Canyon National Park’s most significant resources, its geology, is now sharply focused towards informal geoscience education.

The theme of the exhibition is time. The Trail of Time (pictured on the cover of this magazine) is a giant geologic timeline, where every meter along the trail, each of which is identified by a bronze marker, represents one million years of Earth’s history. The timeline is situated on the highly visited south rim, between the newly renovated geology museum at Yavapai Point and the historic lodges of Grand Canyon Village. It follows the paved, wheelchair-accessible Rim Trail, offering all manner of opportunities for multi-generational family exploration. The walk from the “Today” marker near Yavapai Museum to Grand Canyon’s oldest rock at the east end of the village is a 1,840-meter (1.1 mile) long walk along the timeline trail that covers 1.84 billion years. Amazingly, it’s another 2,720 meters (1.7 miles) along the timeline to the 4.56-billion-year-old age of the Earth, near Maricopa Point. After walking these distances visitors express a visceral understanding of geologic time saying, “It’s a long time, the Earth is really old!” or “I knew the number, that [Grand Canyon’s oldest rock] was 1.8 billion years old, but you don’t really get a grasp of how much that is until you’ve walked 1.8 billion years!”

Interpreted along the timeline are Grand Canyon rocks, wayside exhibits, and viewing tubes that relate Grand Canyon’s history and landscape to geologic time. Boulder-sized examples of each of Grand Canyon’s rock layers, many collected by raft from the canyon’s bottom, have been placed along the trail at their “birthdays.” People talk about and touch these beautiful examples of 1.7-billion-year-old folds, 1.2 billion-year-old mud cracks, 800-million-year old algal reefs, and 270-million-year-old fossils. Viewing tubes connect time along the horizontal timeline trail to the specific rock layers down in the canyon. Wayside exhibits explain key events that helped produce the landscape visitors see today at Grand Canyon. One key exhibit, just six meters from the start of the main trail, explains that the Colorado River has carved Grand Canyon in the last 6 million years or six long steps on the timeline. The main trail also has an introductory trail segment or “on ramp” where the first million years is stretched out to link human timescales (e.g., visitors’ birthdays and key events in early Grand Canyon explorations) with geologic timescales (e.g., climate change and Grand Canyon’s recent volcanic eruptions).

The project has incorporated extensive evaluation throughout the development process by assessing what works best to enhance visitor experiences. The trail is also being used as an instrument to research how people from all walks of life comprehend geologic time and geologic processes. This research is helping identify what conceptions and misconceptions people start with. On-site evaluation shows that 90 percent of respondents used one or more elements of the exhibition and that many were inspired to think about geology and engage in meaningful geology-related conversations. Many also came away with increased geologic reasoning skills, increased geologic vocabulary, and a visceral understanding of geologic time. The Trail of Time has been called the largest geoscience education exhibition at the world’s grandest landscape. As such, it is uniquely poised to make a difference for informal geoscience education and interpretation. For more information, and to see the evaluation results: http://tot.unm.edu.

A billion years of time is nearly unimaginable. The remains of ancient animals and plants preserved in rocks spanning more than a billion years reveal a complex and interesting story of evolving life on a dynamic planet. The fossil record of North America is well represented by paleontological discoveries throughout the National Park System of the United States. Fossils are non-renewable resources and have been documented in at least 230 National Park Service (NPS) areas ranging from the most primitive microscopic life forms to the giants of the ice age. Fossils connect us to past worlds on our own planet and present excellent interpretive opportunities.

Petrified bones, teeth, shells, leaves, wood, and footprints uncovered in parks yield information about prehistoric biodiversity, past climatic changes, and continuously evolving paleoecosystems. Millions of fossil fish are preserved in 50-million-year-old lake sediments within and surrounding Fossil Butte National Monument in Wyoming. Marine reptiles, sharks, and other sea life inhabited a shallow inland sea bisecting North America during the time of the dinosaurs. Their fossils are known from several national parks extending from Texas to the tundra. Fossilized sloth dung from caves in Guadalupe Mountains National Park and Grand Canyon National Park yields information on diet and climate. Fossil termite nests in petrified logs, leaf impressions with evidence of insect chewing, or predator bite marks in ancient bones demonstrate interactions between organisms of the past.

Long before the footsteps of Union and Confederate soldiers marched across the fields of Gettysburg, dinosaurs left their footprints in mud. Today these tracks are preserved in blocks of stone used in the construction of a bridge on the battlefield. These tracks are one example of fossils preserved in a cultural resource context throughout the National Park System. Others include projectile points made of agatized petrified wood, ornamental objects incorporating fossils recovered from archeological sites, and historic structures with fossiliferous building stones.

Museums around the world enable the public to view fossils in displays and exhibits, sometimes including complete skeletons, which have been cleaned, repaired, and put back together. The national parks provide wonderful outdoor opportunities for visitors to encounter fossils in their natural state—literally “in the wild” within rocks. The personal discovery of a fossil in the field, regardless of whether the remains are common or rare, is exciting for the visitor and typically presents an educational moment. Such moments of discovery frequently generate discussions and questions about the science and methods of paleontology, including, “What is a fossil?” and “How are fossils formed?” and “What is the relationship between a fossil and the rock in which it is preserved?”

In March 2009, President Obama signed into law the Paleontological Resources Preservation Act. The legislation mandates federal agencies, including the NPS, to establish education programs to increase public awareness about the significance of paleontological resources. In support of this mandate, the NPS and over 130 partners hosted the first annual National Fossil Day on October 13, 2010. National Fossil Day was a nationwide event celebrating the scientific and educational values of fossils (http://nature.nps.gov/geology/nationalfossilday).

From fossil localities and caves deep within the Grand Canyon to remote sites high in the mountains of Glacier National Park, scientists have carefully documented non-renewable paleontological resources. Collectively, National Park Service fossils span more than a billion years of Earth’s history and yield important scientific information related to the history of life. Through careful management and stewardship, future fossil discoveries in the national parks will continue to expand our understanding of the prehistoric world and our evolving planet.

The Green Door: Touching Nature, Touching Magic

14 Feb

By Wren Smith
Originally published January/February 2011

When we encourage creativity and tactile, hands-on contact with plants, we provide visitors a passport through the Green Door. On the other side of the Green Door awaits a playground, and like any good playground, it is also a school. Much of the learning in this playground happens where our five senses, stimulated by a heightened level of engagement with tangible touchable nature, activate our sixth sense—the imagination.

The seedpods of the wild indigo catch my eye and I pause to inspect. “These would make excellent boats for the fairy folks,” I muse as I pick a few and hold the dried pea-like pods in my hand. Disturbed by my presence, a white-throated sparrow flies from a nearby clump of switch grass. I heard his plaintive, “poor-sam-peabody-peabody” call earlier in the week, but now the snowy patch of feathers on his throat suggests that winter is at hand. My garden has been transformed from the lush vitality of the growing season to more somber shades of tan, gray, and brown. Yet despite the change of palette, I have once again stepped through the Green Door. Regardless of the season, stopping to notice plants, to experience their texture, fragrance, or form opens us to new discoveries and reveals aspects from both the real world of nature and the imaginative world of spirit.

Volunteer naturalist Molly Teviso-Rona assists customers at the Fairy Market.

A mother sits on a rock in the woods with three small children. She turns over a play building permit and reads aloud the simple building code printed on the back of the paper. The children are squirrelly and anxious to get started, yet appear to be listening:

Be respectful of the space. Please don’t pull up living plants….Fairies prefer homes built from natural material…. Use your imagination…. Don’t be a perfectionist…. Be safe, watch for poison ivy, ticks….

As she continues reading, a little girl chirps, “What’s a perfectionist?” I can’t hear the mother’s response, but the girl nods in understanding.

Two young home builders show off their newly constructed fairy house.

A boy, perhaps six years old with eager eyes, clutches a brown bag, opens it, reaches in, and hands a quarter-size cardboard token to one of the “shopkeepers” standing across the counter at the Fairy Market. The large tables hold several shallow boxes and baskets containing an assortment of natural treasures (seedpods, dried flowers, and pieces of lichen-encrusted bark), which participants can exchange for tokens. Homebuilders for the fairy folks are allowed to use nonliving materials, fallen leaves, sticks, stones, etc., found within the permitted building zone, but all other materials must be “purchased” with tokens.

“Is this the one you want?” a fairy-clad shopkeeper asks, as she leans across the counter to meet the youngster’s gaze. “Oh, that will indeed make a great stairway!” she says. Her eyes twinkle as she hands the carefully selected piece of grapevine tendril to the young builder. The shopkeeper then inquires as to how many more tokens the boy has in his bag.

“Eight,” he responds after a brief calculation. “This is my second purchase, I’ll be back,” he says, looking over his shoulder as he dashes away clutching the miniature stairway in one hand and his bag of tokens in the other.

A father crouches on the ground and peers into a hollow log recently converted into a fairy house. His children, a little boy and a younger girl, are beaming with pride. “Look Daddy, we used these little sticks to make a fenced-in-yard,” says the boy as he points to the toothpick-size fence posts, lined up to form a small enclosure.

“And I made them a bathtub from this curled up leaf,” chimes the girl, “and look we found an empty snail shell for their living room. We gave them a fireplace, a bed, a couch and everything.” The father oohs and aahs, then shows off the miniature swing set he just added to the fairy’s backyard. Who says fairy house building is just for kids?

Fairy houses are left behind as monuments to the imagination.

Building Inspector Deanna Rushing looks official with her cap, badge, and clipboard as she patrols the new construction in the High-Density Zone of the Fairy Village. While she could issue tickets for infractions of the building code, she encounters few of them. Mostly she and the other volunteer building inspectors are on hand to offer suggestions, minimize the impact on the grounds, and ensure that safety concerns like poison ivy and ticks are addressed.

After volunteering as a building inspector for Bernheim’s Fairy Village, Deanna is charmed. “Once participants select their site and have a chance to explore it, their imaginations expand.” she says. They discover all sorts of possibilities in the bits of bark, twigs, and such. The velvety leaves of common mullein and lambs ear (both available at the Fairy Market) might make great blankets or fairy upholstery, but there is something about getting to know a place tactilely that helps feed the imagination. Some twigs are sturdy yet flexible; pieces of sloughed bark are versatile and can be fashioned into tables, porches, overhangs, and even walls. The large waxy leaves of the southern magnolia feel like perfect fairy roofing material.

Deanna reports that children and their parents (also grandparents, uncles, and aunts) constructed their tiny dwellings with a real focus on making comfortable homes for the fairies. But according to Deanna, comfort wasn’t the only principle that guided their process. She said, “Some considered hygiene, nutrition, community, and lots of ways to have fun. There were climbing ropes and vines to get to different areas of the house, soft velvety couches or chairs made from mullein leaves, dried flowers and hickory nut shells, indoor and outdoor showers. There were lots of ‘secret’ places for fairies to do things that we might not be privy to—places drawn by the imagination but respectfully unexamined, lest the fairies find it uninhabitable. I think the kids’ and parents’ imaginations meet on equal footing.”

This fairy village and the magic of this day were a direct result of my involvement with NAI. In February 2009 during the NAI Region 3 Workshop in western Kentucky, Michael Kirschman, division director for Mecklenburg County Nature Preserves, approached me with his usual enthusiastic greetings. Then he added, “Wren, of all people, you have to incorporate a fairy house festival into your programming!”

Michael knew that I would be receptive to his suggestion. He’d seen some of the little fairy creatures I make from natural materials. He may have known that I made fairy houses and occasionally incorporated them into programs and activities over the years, but he correctly assumed that I had never hosted a fairy house festival. Michael’s enthusiasm was contagious as he shared how the staff at the Latta Plantation near Charlotte, North Carolina, pulled off an amazing fairy house festival the previous February. With Michael’s encouragement, photos, and statistics from the first fairy house festival and marketing ideas (such as adding a costume contest) shared by Gail Lemiec, the genius behind their event, I was able to successfully petition our programs committee to include fairy house building in a major event at Bernheim Arboretum and Research Forest. Bloomfest was on the calendar as a new annual spring event. But we needed something besides the scheduled plant lectures, hikes, and plant sales—something that may have broader appeal to families with small children. Thus when Bernheim lunched our first Bloomfest in May 2009, we incorporated our first fairy house village as a major part of the day’s activities.

We didn’t know what to expect. Some co-workers questioned the connection between making fairy houses and our mission (connecting people with nature). Some suggested that this sort of activity would probably appeal only to little girls of a certain age. Others were concerned about the potential for resource destruction. As interpreters, we know that an idea is only as good as its execution, and the execution is only as good as the marketing and organization of supplies and volunteers.

Our plans needed to address and minimize the impact on the building site and limit “willy-nilly” collecting of natural materials by visitors. Sometimes when you address one problem you create new opportunities. It occurred to me that we could limit the temptation of visitors to collect outside our designated “fairy construction zone” if we established a place for them to obtain additional materials, thus the Fairy Market. Here shoppers could select from a large variety of interesting natural materials (dried flowers, seed pods, grape vine tendrils). These materials were carefully collected and organized weeks in advance by staff and volunteers.

To prevent greedy grabbing of the market’s materials, we gave each permit holder a bag of 10 tokens (leftover leaf-shaped cutouts from a local greeting card factory). An unexpected bonus in establishing this market is that not only did it limit unbridled collecting of natural materials, it also gave participants an opportunity to touch and learn about the real world of nature in a more thoughtful manner. Shoppers at the Fairy Market selected from a variety of interesting natural materials spread out smorgasbord fashion. They encountered interpreters who in the guise of shopkeepers answered questions or added enough guided commentary to be helpful without being intrusive. The large acorn caps from saw tooth and bur oaks were favorite bathtub fixtures and the velvety red inflorescence of the giant cockscomb where especially popular as “upscale” pillows and upholstery materials.

Young builders practiced math and budgeting as they deliberated each purchase. A shopper might purchase a grapevine tendril for one token, or select a honey locust pod in exchange for two tokens. One basket contained dried flowers and a sign reading, “1 token = 5 flowers”.

In the construction zone, children and their parents freely searched and found all sorts of building materials such as pieces of bark, hollow logs, rocky grottos, and an assortment of “builders twigs”—the all-important structural support supplied by the various twigs and branches in the shape of letters, including Y, V, T, and W. In the process of searching, participants not only developed a more intimate connection with the plants, they also discovered creatures from the other kingdoms.

Even though the morning brought showers and limited construction, the afternoon clearing allowed fairy houses to spring up like mushrooms after a rain. Visitors built 106 fairy houses in just a few hours. Most of these were constructed by families. Moms, dads, and children were down on their haunches, looking closely at twigs, rocks, leaves. They were touching the earth and being touched by it. I like to imagine that they had stepped through the Green Door. They had certainly entered the place where children (and those of us who are still children at heart) are able to express the inner world of the spirit while connecting more intimately with the real world of nature.

It is easy to help your visitors step through the Green Door. There is no magic word to incant, no lock to fumble with, and no key to turn. Instead turn your attention to the green and growing things. With a little imagination, you and your visitors will more fully encounter the complexities and mysteries of the natural world. In the process you may not only discover the intricacies of aster blossoms and hollyhocks, but also the tiny stars and fairy gowns hidden there.

Stories in Stone: Interpreting Geology at Johnson’s Shut-Ins State Park

08 Feb

By Therese Mckee
Originally published January/February 2011

When a massive flood sent billions of gallons of water rushing through Johnson’s Shut-Ins State Park (Missouri) six years ago, shattered rock and other debris covered the hiking trails and campsites and littered the swimming holes that crowds of visitors enjoyed each year. Acquired in 1955, Johnson’s Shut-Ins was known to outdoor enthusiasts as an 8,500-acre nature oasis, tucked in the Ozark Mountains along the Black River in Reynolds County, Missouri, 80 miles southwest of St. Louis. Its geological “shut-ins” are among the oldest exposed rock in the nation.

The damage and debris were monumental. The breach of the Taum Sauk Reservoir destroyed nearly every man-made structure in the park. Uprooted trees and overturned soil ravaged surrounding hillsides. As planning crews assessed what remained and focused on the barren land that had been left behind, they came to realize that the flood had exposed even more geological history. A large bed of Taum Sauk rhyolite rock was discovered, dating back 1.4 billion years when volcanoes exploded to create the nearby St. Francois Mountains. In addition, rocks from at least three other geological eras were found within the rubble, as well as a sand beach near the top of Taum Sauk believed to be 530-million-years-old.

Within days, construction teams were at work clearing the area of remnants of the flood, and Missouri’s state park planning division began seeking the guidance of design teams to plan a new park. I was engaged as lead interpretive designer of a multi-member design team.

After examining Johnson’s Shut-Ins, the initial concept of the design team focused on taking advantage of the rhyolite, dolomite, granite, sandstone, and chert that work crews had been harvesting and incorporating them into the design. Further, we worked to create an interwoven series of storylines that responded to the desire of park officials to incorporate history, nature, and the park’s native geological elements into its restoration and rebuilding. The team’s interpretive design knowledge—coupled with a belief that native stone needed to be a central interpretive material—was the creative spark the master planners of the park were seeking.

“Earth’s Time Spiral” provides an explanation of Earth’s age that couples geological material and cylindrical shapes to create an interactive, educational mosaic.

Designers entered the project fully aware of the challenge—to include the great number of topics requested by Missouri Department of Natural Resources officials with a focus on one of the toughest topics to present in an interesting fashion to audiences—geology! Based on facts gleaned from more than 20 scientists, historians, and geologists recruited to assist the design team, interpretive storylines were created to make the facts easy to understand, blending artistry with intellectual engagement.

The overall design plan to attract, inspire, and educate visitors from all walks of life included 10 interpretive storylines, a visitor center with 3,000 square feet of exhibit area featuring interactive displays and tangible artifacts, an AV theater, a visitor information station for collecting their memories of the park, and an interpretive retail area. Actually, these were just the start of the designers’ elaboration. The interpretive program also includes six miles of trails, three interpretive pavilions, three stone mosaic plazas totaling 1,700 square feet, three scenic overlooks, an amphitheater, an outdoor classroom, a geology-themed playground, live programs hosted by park rangers, and 10 downloadable podcasts describing each of the 10 storylines.

A mosaic river flows from the entry of the visitor center to a small theater made of rock modeled to form a cave.

Sensitive to making a natural presentation that was compatible with the park’s landscape, designers used locally quarried Missouri red granite and aux vases limestone for structures whenever possible. From the stone-mosaic plazas to the interpretive signs, the team made sure to integrate natural materials into structures parkwide. Seat walls and building facades were constructed of stone rubble deposited on the site after the disaster.

As noted, many of the interpretive storylines directly reflect on the geology of the park, including:

  • A “Landscape of Voices” at the orientation center introduces visitors to the wild landscape of Johnson’s Shut-Ins State Park, telling of violent volcanic eruptions, ancient geology, the power of water, and the biodiversity of the St. Francois Mountains. Visitors are encouraged to explore the Black River Center, pavilions, and trails to learn more about this extraordinary place.
  • “A Slice of Time” at a pavilion and overlook features exposed geology in the Scour Channel with rocks dating back 1.4 billion years and shows how the mountains were formed.
  • “If These Rocks Could Talk” at Shut-Ins Overlook tells a story of ancient volcanic eruptions, followed by millions of years of erosion and movement of water as it carved and shaped the unusual narrow gorge we call the “shut-ins.”
  • The “Power of Water” display at Boulder Pavilion shows visitors how the powerful flow of water has sculpted rock, moved giant boulders, eroded millions of years of geologic history, and changed the face of the earth. Guests are invited to visit the river, the fens, the boulder field, and other locations to see the water at work.
  • Children play at the “Giant Rock Box Discovery” playground.

These additional storylines combine geology with the natural and cultural history of the region:

  • An “Ozark Oasis” at Fen Pavilion details a unique combination of a continuous groundwater stream that weaves through bedrock pushing up just below the surface of the land. The special set of conditions creates a groundwater-fed wetland, or “fen,” that supports a great diversity of plant and animal life. Overlooking this protected area is a pavilion that provides a panoramic view of the fen and an interpretive demonstration of what lives inside.
  • The “Heart of the Wilderness” at Wild Area Trailhead offers two rugged Missouri wild areas for experienced backcountry hikers and campers. Covering more than 6,000 acres, the East Fork Wild Area and the Goggins Mountain Wild Area are undeveloped and preserved for their unique wilderness values.
  • “Nature’s Mosaic” at Shut-Ins Trailhead is a 1,200-square-foot stone and metal mosaic made to reflect the hundreds of diverse, interconnected living organisms that thrive within the park. From the tops of the tallest trees to the valley below, the woodlands, glades, river, and associated habitats teem with life.
  • The Ozark Trail explains to visitors that the trail runs through Missouri from the St. Louis area to the Arkansas border. Some of the most scenic and challenging parts of the Ozark Trail run through Johnson’s Shut-Ins State Park. The Ozark Trail can be reached from three local trails within the park.
  • “Paths Through Time” at Cemetery Trail takes visitors on a journey that commemorates the early days of the region. The rocky terrain of the area formed by the rare geology, limited land use, and historically supported small settlements that relied on gathering and subsistence farming. Early pioneers that settled in the region were descendants of the Scots-Irish from Appalachia who sought free and open land. A walking trail with interpretive signs provides a path to a cemetery of the original families that settled the park’s lands.
  • “Making Memories” at the campground amphitheater and orientation center enlivens the memories of the shut-ins that have attracted people to this area for generations. Today, visitors are invited to join with park staff and the Missouri Department of Natural Resources to help ensure the continued beauty and environmental health of this extraordinary place. A technologically advanced device records images, narration, and written stories from visitors to the park.

The entire project from interpretive master planning and design conception through installation was completed in three years. Due to the vision of the design team and their interpretation of the geology, natural history, and culture of Johnson’s Shut-Ins State Park, visitors today not only get to return to the comfortable campsites and pristine hiking trails they once frequented—they also enjoy a unique educational experience and interactive exposure to its many geological treasures. Johnson’s Shut-Ins is truly a “landscape of voices.”

Training with the Whole Brain in Mind

02 Feb

By Kris Whipple
Originally published January/February 2011

What’s your training style? Are you systematic and analytical (think outlines, agendas, and worksheets) or do your training sessions lean more toward the creative and spontaneous with games, role-playing, and brainstorming activities? If either sounds like you, thank the dominant side of your brain. Unfortunately, this same dominant side, which along with other variables dictates your personality, behaviors, and preferences, may also prevent you from connecting with everyone in your training audience. Why?

The cerebral cortex, the part of the brain that controls rational functions, is made up of two halves, or hemispheres. These are connected by a thick band of nerve fibers (the corpus collosum) that sends messages back and forth in a cross-wired fashion, so your right hemisphere controls your left side and vice versa. Brain research has confirmed that just as you have a dominant hand, eye, and even a dominant foot, you probably have a dominant side of your brain. And while no one is totally left-brained or right-brained, learning via the preferred side is faster and easier because your dominant side has more neural connections. This means that when learning is new, difficult, or stressful, we automatically go to our preferred side.

The fact that most of us have strongly lateralized brains is probably no accident, according to Dr. Michael Corballis, professor of psychology at the University of Auckland, New Zealand. Early in human history, and possibly even in our pre-human ancestors, evolution delegated different cognitive responsibilities to the brain’s two hemispheres. This allowed our brains to become more efficient and smaller, meaning fewer calories were needed to keep it running.

The concept of right-brain and left-brain thinking is based on studies first developed by Nobel Prize-winning American psychobiologist Roger W. Sperry in the 1960s. Through studies with “split-brain” patients (whose two hemispheres could not communicate with each other due to a severed corpus callosum), he discovered that the human brain has two very different ways of thinking. While the idea of left-brain versus right-brain continues to be a controversial subject among scientists and academics, most scientists and researchers agree that there are definite differences in the way each hemisphere works.

The left side of the brain is the seat of language. It processes information in a logical, linear manner, by taking pieces of information, arranging them in a sequential order, then drawing conclusions and forming strategies. To the left-brain learner, facts and symbols rule. They’re comfortable with words, names, numbers, and scientific data. If your thought processes tend to be more analytical, objective, and detailed-oriented, you may be a left-brained learner.

Unlike the verbally skilled left hemisphere, the right hemisphere focuses on the visual. Rather than processing information sequentially, the right brain processes information intuitively, randomly, and from whole to part, starting with the answer and working back. If you find yourself pulling answers out of the air without knowing how you got them; if you focus on the big picture before the details; if you’re creative, emotional, and spatially skilled; and if you learn best by doing rather than listening, you might be a right-brained learner.

Unfortunately for right-brained learners, modern society and learning institutions tend to favor left-brain modes of thinking that focus on logical thinking, analysis, and accuracy, while downplaying the right-brain modes of thinking that focus on aesthetics, feeling, and creativity. Experiments show that most children rank highly creative (right brain) before entering school. But because educational systems place a higher value on left-brain skills like mathematics, science, and language than on drawing or using our imaginations, only 10 percent of these same children will rank highly creative by age seven. By the time we are adults, high creativity remains in only two percent of the population.

It’s obvious that in order to foster a more whole-brained training experience, we need to include training techniques that connect with both right- and left-brained learners. So how do you ensure that you connect with everyone in your training audience?

If you naturally live in the left side of your brain, include right-brain activities that promote creativity and synthesis like role playing, brainstorming, and creative problem solving. Remember that right-brain learners do best by seeing, touching, doing, and being in the middle of things. Adding small group activities, hands-on exercises, metaphors, analogies, and visuals to your training repertoire will increase your audience’s right-brained connections and ensure a more whole-brained approach.

And if you’re a right-brain-dominant trainer? Adding organizational tools like written agendas and outlines as well as analytical activities like worksheets, fact sheets, and discussion will support the linear learning needs and desire for details and data that are characteristic of left-brain learners.

Tilden’s principles state that effective interpretation “must address itself to the whole man.” By better understanding the influence of hemispheric dominance on you and your participants, and by promoting a whole-brain learning approach, you are one step closer to ensuring your training not only addresses the “whole man” but your whole training audience as well.
