NCSA/UIUC Collaboration: UIUC Astronomy Students Encounter the Web

by Allison Miller


"The purpose of this assignment is for you to begin to create your home page. Everyone gets full credit for 'just showing up' in cyberspace by the due date of this exploration."

Does this sound like any undergraduate assignment you remember? Maybe not, but it does ring a bell with the students who enrolled in the spring semester of Astronomy 100, Section 2. This assignment was given as part of a Web Explorations project to the approximately 200 students of Michael Norman, NCSA senior research scientist and UIUC professor in astronomy.


The Web as a resource

One of Norman's primary goals is to get his students excited about the subject of astronomy. Norman's secondary goal is to expose his students to the World Wide Web and to introduce them to using the Web as an educational resource. Umesh Thakkar, program coordinator of science education in NCSA's Education and Outreach Division, was enlisted to help reach this goal.

'The motivation [for using the Web] comes from two directions," says Norman. "One is that it is almost a mandate from the administration to use Web-based learning in education. I also realize that in astronomy there is an enormous amount of material on the Web, probably more than in any other field. That is because astronomy has been a digital science for at least a decade. So I knew that there was a lot out there, and I wanted to expose the students to those resources."


Exploring the Web

Norman has incorporated into his curriculum a section called Web Explorations in which students are encouraged to explore some facet of astronomy. The explorations are meant to give students first-hand experience rather than second-hand information. Students individually explore the World Wide Web's astronomical sites, construct personal Web pages, and build a Web-based group project.

"Curriculum drives the use of technology in classrooms. If the Web can enhance student learning or classroom instruction, then its use should be explored," says Thakkar. "Much astronomy information is available on the Web, so it was a natural for this approach."


Moving onto the Web

Before the first Web Explorations assignment was given, Norman surveyed the students to discover their previous experience with the Web. Of the 178 students replying to the survey, 96% actively used email, while 63% had been on the World Wide Web before. The first project required that all students in the course go online to create their own Web pages. Although the composition of the pages vary from complex HTML (Hypertext Markup Language) to reconstructions of the simple class model, the achievement is the same. All the students--some of whom knew little about the Web before the assignment--now have their own creations online.

"The first assignment was to create a Web page, and the students did that sort of kicking and screaming," says Norman. "But once they learned how to do it, the majority of them felt empowered by the experience. They had heard about the Web. In fact more than half of them had used the Web, but they had no idea how to create their own Web pages. This gave them an excuse to learn."


Interacting on the Web

"Web Explorations began with Dr. Norman providing the students in the classrooms with an appetizer on modern astronomy via the Web," says Thakkar. "The assignment was very simple and our goal was very modest--to get students interested in the Web. He has an extensive background in computing and astronomy, and the Web seemed the ideal vehicle to showcase to students. For instance new planets had been discovered by two astronomers at San Francisco State University. Dr. Norman showed their site on the Web and talked about it. He used the Web in a very effective manner to get students motivated."

"The Web's popularity is growing," adds Thakkar. "We are moving ahead from just browsing to interactivity on the Web for student-directed learning. Of course it is usually easy for engineering and science students. They generally have a computing background. There needs to be an effort to provide opportunities to nonscience majors in the use and practice of the World Wide Web to prepare them for the future."

Hands-On Universe Enables Astronomical Exploration

by Fran Bond

A recent lecture/demonstration of Hands-On Universe (HOU), an educational project for high school students learning astronomy, was sponsored by NCSA's Resource for Science Education (RSE) program with guidance from NCSA senior research scientist Michael Norman.

Via the World Wide Web, HOU links classrooms to automated telescopes at professional observatories. Students are able to download images or request new observations. They use HOU-IP--a Windows- and Macintosh-based image-processing software program developed specifically for high school students--to manipulate and analyze images. HOU follows standards set down by national agencies for implementation and teacher support.

Jodi Asbell-Clarke

Jodi Asbell-Clarke introduced the HOU project to about 20 local teachers and spoke to Norman's Astronomy 100 class. Asbell-Clarke develops HOU curriculum units working through TERC, a private, nonprofit education organization in Cambridge, MA. (TERC is a research and development organization that has a commitment to improve mathematics and science learning and teaching.)

HOU is funded by Lawrence Berkeley Laboratories, Berkeley, CA. Carl Pennypacker, a Lawrence Berkeley cosmologist, developed the program out of his research to help reform science education. NSF and the Department of Energy also support the program.

Currently used in approximately 30 high schools around the nation, the goal is to expand to as many as 700 sites in middle schools and informal education centers, such as museums. This year it is anticipated that 120 new sites will use HOU.
