  • Education: What Are We Doing When We Teach Computing in Schools? (CACM May 2015, pp24-26) | astrofoto.org
    attended past tense started a Software Engineering Pilot Program two years ago It s not clear where the author of that program got the curriculum and since he left before it even got underweigh it s not clear we ll find out But it s also not clear what the basis for evaluating the program s success will be In the public education arena success is often measured either by standardized exams of debatable value or by popular response Neither will help us to know if we are really improving student s knowledge of how computing works Roland Roberts s blog Log in to post comments Printer friendly version PDF version Navigation Calendar Gallery Constellations Messier Objects M27 The Dumbell Nebula Resources Astronomy Books Buying A Star Buying A Telescope Clubs and Organizations General Interest Imaging and Astrophotography Magazines Mailing Lists and News Groups Science Toy Suppliers Software Weather Information Tips and Tricks Roland s Corner Recent content About Copyright Search form Search User login Username Password Request new password Science Daily Mercury Mercury gets a meteoroid shower from Comet Encke Mercury gets a meteoroid shower from Comet Encke More Science Daily Venus The aliens are silent because they re dead The aliens are silent because they re dead More Science Daily Mars Antarctic fungi survive Martian conditions on the International Space Station Antarctic fungi survive Martian conditions on the International Space Station Rotation speed may be bad news for Red Planet pioneers Rotation speed may be bad news for Red Planet pioneers The aliens are silent because they re dead More Science Daily Jupiter New study challenges Jupiter s role as planetary shield protecting Earth from comet impacts New study challenges Jupiter s role as planetary shield protecting Earth from comet impacts NASA telescopes detect Jupiter like storm on small star NASA telescopes detect Jupiter like storm on small star Simulating the jet streams and anticyclones of Jupiter and Saturn More Science Daily Saturn Cassini completes final close Enceladus flyby Cassini completes final close Enceladus flyby How water escapes from Saturn Magnetic reconnection How water escapes from Saturn Magnetic reconnection Explosive energy in Saturn s magnetic bubble More Science Daily Neptune Evidence of a real ninth planet discovered Evidence of a real ninth planet discovered Mars to lose its largest moon Phobos but gain a ring Mars to lose its largest moon Phobos but gain a ring Simulation of 3 D exotic clouds on an exoplanet More Science Daily Uranus Jupiter bumped giant planet from our solar system This solar system isn t big enough for the both of us Jupiter More Science Daily Pluto Earth like planets have Earth like interiors Earth like planets have Earth like interiors Evidence of a real ninth planet discovered Evidence of a real ninth planet discovered New Horizons returns first of the best images of Pluto More Science Daily Comets and Asteroids Earth like planets have Earth like interiors Earth like planets have Earth like interiors Artistic space odyssey to broadcast people

    21 43 It s been a busy year I bought this at NEAF back in April and have only just now been able to get out and give it a spin The new feature of course is the autoguiding With the original TT320 the specifications state a periodic error limit of 5 arcseconds per 5 minutes As it works out when using my Borg 45ED lens the pixels in my Canon 350D are about 5 arcseconds wide What I ve seen is that I can with great care get exposures up to 4 minutes long but some of them invariably show trailing and have to be thrown out Read more about Performance of AstroTrac TT320X AG Log in to post comments Happy June Solstice Day Submitted by Roland Roberts on Tue 06 22 2010 10 19 For those of you who missed it yesterday marked the June solstice the first day of summer Of course my children disagree about the first day of summer part since they know the first day of summer doesn t really happen until after school is out and here in New York City the last day of school is June 28 Read more about Happy June Solstice Day Log in to post comments Light Pollution in Missouri Submitted by Roland Roberts on Fri 02 19 2010 11 30 Missouri is my home state I grew up in what was then a rural area south of St Louis in Arnold Seeing the stars at night was no big deal and something I took for granted Read more about Light Pollution in Missouri Log in to post comments Careers in Physics Submitted by Roland Roberts on Thu 02 11 2010 20 32 Okay here is a resource for your next career day The American Physical Society has put together a slideshow you can download I need to browse this so I can work on my spiel for career day at my son s middle school IS 30 Read more about Careers in Physics Log in to post comments Sun trek Educational Site Submitted by Roland Roberts on Thu 02 11 2010 20 11 The January 2010 issue of Physics Today s web watch section mentioned the Sun trek web site which contains a number of resource for learning about the Sun and it s effect on the Earth The material is varied and the comment about being devoted to teaching schoolchildren is a bit vague on the age group but the format includes a large number of images and other materials that make it engaging certainly for middle school and possibly for older elementary students depending on the lesson Of course some of the material is clearly target Read more about Sun trek Educational Site Log in to post comments Pages first previous 1 2 3 4 5 6 7 8 9 next last Navigation Calendar Gallery Constellations Messier Objects M27 The Dumbell Nebula Resources Astronomy Books Buying A Star Buying A Telescope Clubs and Organizations General
