A NASA videoconferencing program knocks down traditional educational boundaries, drawing together teachers, students, and field experts in a single virtual setting for the benefit of all.
THEY MAY NOT HAVE known it, but in January 2004,  when students from Oxon Hill Middle School in Oxon Hill,  MD, met face-to-face with students at Princess Anne Middle  School, in Virginia Beach, VA, without either group ever stepping  outside of their own classroom door, new ground wascrossed in the continuing passage into 21st century education.
The meeting was conducted via NASA LIVE (Learning  through Interactive Videoconferencing Experiences; http://live.larc.nasa.gov), a free series of videoconferencing programs produced  by NASA’s Langley Center for Distance Learning in  Hampton, VA (http://dlcenter.larc.nasa.gov). NASA LIVE is designed  for K-12 educators and students, allowing teachers and students  to interact with NASA experts in a virtual setting as they  engage in a variety of topics and hands-on activities connecting  science-, technology-, engineering-, and mathematics (STEM)-  related content to NASA research and careers.
The two sets of middle school students were participating in  the first joint NASA Connect/NASA LIVE event, “The Nutrition  and Exercise Challenge.” [Ed. note: The “Challenge” was a  collaborative project led by program moderators Chris Giersch,  NASA Connect program manager, and Katrina Townes-Young,  NASA LIVE program manager.] Accepting the challenge presented  by the NASA Connect program, titled “Better Health  From Space to Earth,” students worked in groups to develop  daily meal and exercise plans for individuals with special needs.
NASA LIVE offers 30- to 60-minute videoconferences  among its researchers and students throughout North America  and beyond. Each videoconference incorporates a variety of  multimedia and hands-on activities that enrich classroom  instruction. Teachers and students participating in a NASA  LIVE event have the opportunity to establish real-world connections  with experts in STEM areas as they interact with and  learn from the researchers who play an important role in aeronautics  and space exploration (such as the Return to Flight, the  Mars Exploration Rovers, Hyper X-43A, geospatial technologies,  and weather and satellite tracking). Past participants connecting  to NASA experts have represented various  geographical areas including Hong Kong, London, New Mexico,  New York, New Zealand, Norway, Puerto Rico, Texas,  and a host of other locations.
Extending the Classroom  
  The NASA LIVE program points up the capability of videoconferencing  to carry student learning beyond traditional,  desk-bound methods. For centuries, teachers and students  knew their places in the classroom: teacher at the fore, students  at their desks, facing forward. Lecturing was all anyone  knew, or was capable of, since the instructor was theonly one with a copy of the book in use.
The globalization of learning has changed education methods  and resources. Today, educators are neither tied to the  four walls of the traditional classroom nor to the language  of a single book. And with the advent of videoconferencing,they’re no longer even tied to one group of students.
Videoconferencing is a telecommunications medium  allowing individuals or groups of people at different locations  to transfer video and audio in a real-time or face-to-face  setting. Originally used by the military to encourage  interaction among soldiers abroad, and by corporations to  facilitate communications between personnel and business  clients, it is now finding a home in today’s global classrooms.  By traveling beyond the physical classroom, K-12  educators are beginning to recognize how videoconferencingbecomes an extension of the classroom.
In the past, distance learning with two-way video and  audio was inaccessible for many professional and academic  organizations. Videoconferencing allows educators and students  at all grade levels to introduce and reinforce subject  matter with real-world experts from various educational and  professional organizations and institutions, as well as withpeers from around the world.

Advantages of Videoconferencing  
  An ideal tool for the digital generation, videoconferencing is  in step with education’s shift away from short, isolated,  teacher-centered lessons to a student-focused, interactive experience.  Sometimes called electronic field trips, videoconferences  (such as the ones held via NASA LIVE) take students  on virtual tours through research centers, zoos, and historical  and cultural sites, bringing them face-to-face with experts and  other students with whom they would otherwise never have  direct contact because of the substantial transportation andadministrative costs involved in bringing the groups together.
There’s almost no end to the benefits of this technology:
  - Videoconferences enable educators in different locations to share information, resources, and any costs involved        without traveling long distances. And students in various        locations can participate in classroom activities without      being physically present.
   - Videoconferencing provides access to a vast array of information        and resources to better meet students’ individual      needs, while encouraging high levels of interaction.
   - Face-to-face interaction increases student motivation and        participation and facilitates the students’ grasp of difficult      or abstract concepts.
   - Positive relationships between educators, students, and        community members are cultivated through effective utilization        of local and distant real-world experts (presenters),        who, because of long distances, difficult travel conditions, or busy schedules, are unable to visit schools or classrooms        as guest speakers. As a result, schools operate more efficiently due to reduced administrative expenses. 
   - Conversation and body language enhance communication        when educators and students see and hear remote      learners in real time. 
   - Educators can meet and match the educational needs and      abilities of their students. 
   - Various learning styles are considered when emphasis is      placed upon long-term, interdisciplinary, student-centered      activities integrated with real-world issues and practices      (US Department of Education, E-Learning: Putting a      World-Class Education at the Fingertips of all Children, 2000). These styles are addressed by a      variety of educational materials available      through videoconferencing. Animations,      audio, graphics, and video      clips enhance the visual learner’s learning      experience; audio communications      appeal to the verbal or linguistic learner;      and kinesthetic learners benefit from      audio and video communications.      Meanwhile, hands-on activities like  “Building an Edible Comet” demonstrated      via NASA LIVE appeal to all students, including    special-needs students. 
   - Academic and social skills are improved. Through group        collaboration and interaction, students develop their communication        and management skills. As students prepare,        present, edit, and provide feedback on projects, their presentation      and speaking skills improve. 
   - Interviews with field experts, as in “The Nutrition and      Exercise Challenge,” provide students with opportunities    to sharpen their listening and note-taking abilities.
   - Opportunities to learn about cultural differences emerge        as students work together with other students and adults        throughout the world, promoting cultural diversity and      tolerance. 
   - Synchronous video communications and teaching strategies        such as question-and-answer sessions or project-based      learning encourage high levels of interaction.
 
In effect, the magic of videoconferencing is that it  removes so many substantial obstacles to learning, including  cost, time, space, distance, physical disabilities, as well  as personal and professional responsibilities. And having  removed those barriers, videoconferencing links students  with experts in a previously inaccessible field as they learn  from a primary source rather than a textbook, as well as  gain access to resources and information that they would  otherwise be shut off from.
Teacher Benefits  
  Imagine that a particular school district requires all of its  science educators to attend a one-hour staff development  workshop on tracking weather. Scheduling conflicts make it  difficult for all the teachers to attend the session. The district’s  solution is to set up a videoconference, or a series of  videoconferences, on the given topic, allowing all teachers  to attend.
As in that example, a great benefit of videoconferencing  is that it ultimately negates time conflicts or location difficulties  that would create scheduling impasses. Educators  also have the flexibility to participate in staff development  activities without leaving their home schools.
Thus, videoconferencing can alleviate the difficulties  associated with staff development programs by providing  unlimited, inspiring opportunities for professional activities.  It enables teachers to share teaching strategies, lesson plans,  and assessment methods with their colleagues nationally  and internationally. The face-to-face communication encourages  the exchange of ideas and suggestions concerning  which lessons or projects work best, in or out of the classroom.  Finding that other teachers are experiencing similar  difficulties with a particular subject area can restore lost  confidence, as well as foster collaboration. Face-to-face discussions  in real time allow educators to resolve problems  and discover new ways to teach material in order to better  prepare students for success in the workplace.
A Lasting Impact  
  As a tangible matter, linked through NASA LIVE, the students  at Oxon Hill and Princess Anne middle schools were  provided with real-world examples of the nature of research  and the range of knowledge within NASA’s Office of Biological  and Physical Research. But they came away with  considerably more than that. Document sharing, exchanging  ideas, problem solving, and decision-making between  the students demanded a high degree of collaboration,  resulting in increased student participation and higher  retention of material, and a greater understanding of cultural  differences. Upon completion, the students presented  their plans to the presentation evaluators, Scott Smith and  Don Hagan, researchers with NASA’s Office of Bioastronautics  at the Johnson Space Center in Houston, TX.
Using videoconferencing resources like NASA LIVE provide  educators, students, and parents with the opportunity  to connect classroom content to related research and  careers. In turn, professional experts help validate understanding,  provide instantaneous feedback, and introduce  practical examples, greatly improving student motivation as  students become active participants. The rewards experienced  by educators who embrace and employ videoconferencing  are well worth the time spent becoming familiar with  a form of technology that is becoming the norm, rather  than the exception. Educators must pass this knowledge on  if they are to prepare the first and subsequent digital generations  for successful roles in society.
