  • Testing Astro Video Capture in Linux
    was in whether or not I would be able to do video capture The latest thing I ve been playing with is setting up for occultation timings Have a look at the IOTA web site occultations org I ve purchased all the equipment a GPS video timer a Supercircuits PC164EX low light camera which they just recently stopped selling and already have telescopes So the question was could I do video capture under Linux I ll worry about analyzing video after I have capture working The answer is yes But its more complicated I have multiple USB capture devices not all of which work equally well The first one I had picked up had drivers software that didn t work particularly well under Window 7 64 bit The video screen would blank out when I started capture which was highly annoying After posting on the IOTA Yahoo group I received some recommendation and went out and bought one of each As it turns out the first one I bought I already had I purchased the Diamond VC500 One Touch I actually already had one That was was the one that was working strangely with the Window 7 64 bit software I m not sure why it was working strangely but it was do bad I had already deleted the old software and my camera had been sitting idle When I received the new one I loaded the software and it worked fine I dug the old VC500 out of a box in the garage and found it worked fine too remember we re still talking Windows 7 here So the next test was for Linux It started out not so good At this point I didn t have a normal lens for the camera so I couldn t be sure

    so I spent a couple of hours today to find replacements This is as much for me as for you so I have one place to go for my space and astronomy news I need to put togther another physics set of feeds too then I m good I also finally took the time to get the image links working correctly The URL rewriting was a bit finicky and things

    the role of Scoutmaster in a local Boy Scout troop The side effect has been limited time for astronomy and some equipment that is languishing from neglect However I can tell you that there are some exciting things I ve been playing with including video equipment to try to get involved in IOTA the International Occultation Timing Association The web site for them is also a little sparse but the

  • NSTA STEM Expo 2013: Common Core and the NGSS
    indulge in a little reminiscence As a high school student in my second year of chemistry junior year for me we spent the entire first quarter doing lab work Maybe a little more than the first quarter The topic was inorganic analysis qualitative cation analysis of solutions After the basic lab safety exercises learning to create out own glasswear well custom tubing and droppers anyway we were thrown into the lab Tests were labs here s a test tube with 2ml of solution what s in it I can safely say that by the end of the quarter we had all mastered the lab techniques and process skills for successful chemistry lab work Most classes can t really afford that much lab work but the one lab day every blue moon is never going to allow anyone to master any of the process skills Students have to both know something and be able to do something I ll throw out a Boy Scout reference This is how most of their merit badge awards work learn something about the topic then do something to demonstrate practical knowledge of the topic Aguilar made a few comments to point out that the adoption of the new standards is not really on any time table yet Most of his comments were what you might expect and perfectly reasonable There are political processes that have to be followed e g public review Board of Education review assessment chagnes etc Two of his comments were particularly noteworthy First if classroom practices are good then actual assessments should not be very important I feel like I need to shout that one from the rooftops Really think about it If what you are doing in the classroom is good then whatever they do for assessments should show that

    First if classroom practices are good then actual assessments should not be very important I feel like I need to shout that one from the rooftops Really think about it If what you are doing in the classroom is good then whatever they do for assessments should show that the students are succeeding Okay there s always the possibility of a really bad assessment pineapples anyone And he omitted the currency testing obsession with getting the highest possible score rather than more simply demonstrating competence But still if classroom practices are good then actual assessments should not be very important There The other comment which I called him on was that states would need to be convinced that the change from current science standards to the NGSS was necessary I pointed out that I felt that was an excessively high bar and not warranted If students currently do mediocre then strictly speaking a change is not necessary I would prefer to see the bar set at the level that the change is expected to be beneficial He agreed and said he would probably change his future wording with the understanding that a beneficial change in the standards still results in a lot of necessary administrative changes the afforementiond political and assessment changes Overall I d say I have two big take aways that I hope will affect teacher practices First that the process skills are the real metric of student understanding Second that classroom practices need to be the focus not assessment 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

    days at the NSTA STEM Expo in St Louis last week and over the next few days I m going to try to do a few posts related to the sessions I attended and things I learned and cool freebies I learned about on the web This is the second year I ve attended and while most of the sessions were not unsurprisingly about astronomy they were all relevant to
