  • 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.
  • CLEA: The last decade
  • CLEA: Modules from 2007A collaboration with the A collaboration with theXMM-Newton mission GONG project
  • New CLEA: Modules in 2008 VIREO - Roemer Speed ofH- R Diagram of Light Experiment Star Clusters Jupiter’s Moon
  • 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
