Astronomy Courses

School teachers know that reality is one of the greatest instructors. Chem-class explosions, telescope observations, and biology field trips can generate faster real learning than textbooks. And the discovery and adventure that accompany such experiences are powerful drivers for inspiring students to continue learning. Some e-Learning products and materials might even be more effective if they also pulled real-time, real-world data and videos into student training.

The challenge, of course, is doing it! Several techniques can help:

• Tapping real-world web sites and cams.
• Merging streaming real-world videos with online LMS training screens.
• Bringing reality into course reference materials.

This article discusses the first of these. And when they appear in the future, Documentation and e-Learning (Parts 5 and 6) will present the others.

To date, documentation and e-Learning developers have come closest to bringing reality into their products when they include Flash animations that show how to perform procedures. But these are predesigned presentations. They may look interactive, but their presentation of information and reaction to user actions are all pre-planned. There is no real exploration in them to fire student interest.

Tapping Real-World Web Sites and Cams

If you already play Flash movies in online course pages, it won’t be a huge technical leap to similarly stream real-time web sites or live video to them. It could even be quite easy.

• Are air traffic controllers your target audience? Here are a few live ATC displays that could be useful in ATC courses:

• All traffic over the U.S. at any time: natca.org/flight-explorer/united-states.aspx
• Atlanta Center (animation builds over time): atcmonitor.com/
• New York JFK (click on a plane to see its details): passur.com/jfk.html

• Are eye doctors your training target?  Then tell your students to log into the following site on Wednesdays between 11 a.m. and 6 p.m. EST, for feeds of live Lasik procedures. They can click “Control the Camera” at the top of the page, to select their view (even one through the surgeon’s own camera) and to control camera tilt, pan, zoom, and focus. (When I zoomed the main camera, the doctor and nurse heard it, turned, and waved.): lasiktv.com/

• Earth-sciences students can access this live demo of the Earth’s rotation at any time. Tell them to note how the Foucault pendulum’s swing direction appears to rotate above the compass points due to the Earth’s actual rotation: pendelcam.kip.uni-heidelberg.de/view/index.shtml

• Meteorology? This Delray Beach, Florida shore cam lets students watch tropical storms and even hurricanes live, as they approach, hit, and pass. The site also offers links to past storm videos: hurricanecity.com/cam.htm

• If you’re creating online training about vulcanology, here’s a list of volcano-cams that display in near real time: volcanolive.com/volcanocams.html

• Zoology? This site lists pages of cams that might be fun in courses for kids. (And yes, the Smithsonian’s “Invertebrate Microscope Cam” can be icky!): search.earthcam.com/search/ec_kids_search.php?cat=ANI&vars=0:128:1

• Astronomy and space science? You’re in luck!:

• NASA’s live Space Shuttle Countdown page: countdown.ksc.nasa.gov/shuttle/countdown/cdt/

• NASA web-TV channels about space exploration often play canned videos, but sometimes broadcast live views of Earth and of real-time space projects from the International Space Station itself: nasa.gov/multimedia/nasatv/

• The latest images from the European Space Agency’s Mars Express Orbiter: webservices.esa.int/blog/blog/6

• Recent views of day and night on Earth from hundreds of orbiting satellites (you can also view the Earth from the direction of the sun or moon): fourmilab.ch/cgi-bin/uncgi/Earth/action?opt=-p

• Just a few real-time and near-real-time solar data/imaging sites:

sprg.ssl.berkeley.edu/shine/suntoday.html

swpc.noaa.gov/solar_sites.html

sohowww.nascom.nasa.gov/

sohowww.nascom.nasa.gov/data/realtime-images.html

solarmonitor.org/

• And these two eye-popping sites allow students to explore the entire visible (and invisible) universe under their own power… using the latest photos from telescopes in space and around the world:

Microsoft WorldWide Telescope: worldwidetelescope.org/Home.aspx

Google Sky (Google has a similar earth/ocean site): google.com/sky/

Also check the WorldWide Telescope site’s educational content (“Guided Tours”) that have been created through the site… plus its instructional videos about making your own.

The above are just a tiny fraction of the content that’s out there about almost any subject. A little searching may reveal resources for your use as well. (But even if content is freely available over the Internet, and its supplier should be thrilled to have more viewers brought to it, be sure to ask about any required permissions and credit.)

And if you have your own real-time video content, you can use a video-streaming service to make it available to multiple web-based students.

Web-cam “telepresence” isn’t always as good as being there (which may not even be possible). But it can be almost as good, and sometimes better. For a web site or cam to be useful for e-Learning, though, it would ideally:

• Refresh in real-time or near-real-time (cams that refresh slower than every 30 seconds may strain viewers’ patience).
• Offer data and images suited to your needs (some cams even webcast in HD now).
• Focus on subjects that will be on-screen much of the time (this eliminates “UFO-cams” and “ghost-cams”).
• Be findable (it can take a lot of searching to find useful content on the web).
• Be online (webcams are easy to take out of service).
• Permit users to control camera movement and focus (usually, through a web queue that grants each viewer a short period of control).
• Be viewable through at least FireFox and Internet Explorer (some cams still don’t work well with Firefox)… and Safari wouldn’t hurt either.

Next time, in Part 5 of my Documentation and e-Learning series, I’ll describe an amazing new tool that e-Learning content creators and documentation writers may all be using within the next few years. So stay tuned!
