Is "Mostly Right" Good Enough?

A Product Review

NASA's Strategic Plan now mandates that they "involve the education community in [their] endeavors to inspire America's students, create learning opportunities, enlighten inquisitive minds," and "communicate widely the content, relevancy, and excitement of NASA's missions and discoveries to inspire and to increase understanding and the broad application of science and technology." The educational community can harvest a substantial crop of information and materials as a result of this mandate.

Two of NASA's products, STARCHILD (for grades K-8) and Imagine The Universe (for grades 9-12), were created by Goddard Space Flight Center through NASA's Office of Space Science. The two packages include information and activity booklets, a CD-ROM, and associated websites. Although generally well put together, the materials could have benefited from closer editing.

There are bits of misinformation or misconceptions in various places in the booklets. For example, in explaining the formation of a star, STARCHILD material states: "As the gas spins faster and faster, it heats up°" Although a forming star does spin faster and faster and heats up, one is not the cause of the other. That the gas is heated by gravitational compression is not mentioned. At a later point a ring is said to form around the stellar core - a planetary nebula. But planetary nebulae are not really rings, and nowhere in the material is the term "planetary nebula" explained to have nothing to do with planets. Also, be careful to use the booklets with the website or CD-ROM. The words "galaxy" and "Big Bang" are not used in the text of the booklet but are in some of its questions.

Imagine The Universe tends to have fewer problems, possibly because it can go into greater detail. But consider the discussion of stellar evolution where it is stated that during helium core collapse, the star's outer layers are said to both "collapse inward toward the core" and be "pushed outward." And helium fusion into carbon "might take a few minutes," a rather significant time-warp of the tens of millions of years that it actually takes. Other minor problems exist, as well.

The website material is appealing and the text generally reliable. But I would have preferred actual images of galaxies and the planets rather than drawings; the galaxies are strange-looking and Neptune is shown highly tilted but Uranus is not. The multiple-choice questions have choices you can't select by a mouse click; only a correct answer button is provided.

Time for New IDEAS!


New at NOVA

NOVA, PBS's enduring science/technology/ nature documentary series, has an accompanying website that adds significant value to the TV show, particularly for teachers. The site, "NOVA Online," provides lesson plans, activities, and other resources intended to build on NOVA episodes and give teachers ideas for using NOVA in the classroom. The website also allows teachers to share ideas, thus making "NOVA Online" a dynamic teacher-centered resource. Go to this useful, and free, resource at http://www.pbs.org/wgbh/nova/teachers.

More ED at the Next AAS Meeting

The 193rd meeting of the American Astronomical Society, to be held in Austin, TX on 5-9 January 1999, will have a variety of education sessions and invited talks. Currently scheduled are sessions titled: "Funding of Educational Initiatives in Astronomy and Space Science," "Astronomy 101: A Continuing Dialogue," and "Computers in Education."


Toshiba and NSTA announce this year's ExploraVision competition. The goal of ExploraVision is to encourage K-12 students to "combine their imaginations with the study of science and technology to explore visions of the future and find solutions for real-life problems." Students work in teams of three or four to create a vision of the future 10-20 years from now by researching their problem and creating a storyboard. In the second round of competition, regional winners produce a video about their innovation. For more information, call 1-800-EXPLOR9. The deadline for entries is 3 February 1999.
