CLEA: An Interactive Teaching and Learning on Earth and Space EducationHakim L. Malasan; Bosscha Observatory, ITB J. Aria Utama; Earth & Space Lab., UPI
HANDS-ON EXCERCISES IN ASTRONOMY?• Hands-on activities, usually in alaboratory setting, help students learnthrough several processes (Hake, 1998).•The problems: Astronomy is observati-onal rather than experimental .•Real observation = (at most cases) timeconsuming.
HANDS-ON EXCERCISES IN ASTRONOMY? (Cont.)• Computer revolution Fast growingof simulation in the astronomy lab.• Simulations are used widely Effectively reduce the risk or expense ofa real-world exercise.
WHY HAVE A LAB COMPONENTTO AN ASTRONOMY COURSE?• “Interactive Engagement” with realastronomy•Deeper understanding of the distinctionbetween observation and interpretation,data and theory.•Appreciation of what astronomers do—the phenomenology of the science.
PROJECT CLEA Contemporary Laboratory Experiences in Astronomy• Laboratory exercises illustrating modern astronomicaltechniques (since 1992).•Designed for non-science majors, but adaptable.•Simulation of measurement process.•Modern digital data and analysis techniques, using,wherever possible, real data.•Modular: each module includes software, studentworkbook(s), technical guide.•Funded by Gettysburg College and the NSF.

EXAMPLES OF FUNDAMENTAL ASTRONOMICAL DATA SETS•The Hubble Guide Star Catalog (coords and mags of~20 million objects); USNO A2 (5 x108 objects), …•The CfA Redshift Survey (mags, coordinates,redshifts of ~5 x 104 galaxies•Pulsar catalogs (coordinates, P, I(υ) for ~103 objects)•Asteroid elements (coords, mags vs time for ~2 x105objects)•Large surveys: 2Mass (IR), SDSS (optical &NIR),2dF (galaxies), etc.
Instrumentation of VIREO•3 Optical/IR Telescopes: various apertures •CCD Camera •IR Camera •Aperture Photometer •Photon-Counting Spectrometer •Multi-Aperture Spectrometer•Radio Telescope: configurable aperture, etc. •3 separately tunable receivers•Analysis tools for •Spectroscopy •Imaging •Astrometry
