New Study Finds Citizen Scientists Can Be Very Accurate | Mental Floss A new analysis of the work of these citizen scientists shows that trusting untrained strangers with scientific data isn’t a terrible idea. As the study in Conservation Biology notes, overall, volunteers classified 98 percent of the images accurately, based on a comparison with expert answers. dy/dan » Blog Archive » The Difference Between Sketching and Graphing Desmos just added sketching into its Activity Builder. That was the result of months of collaboration between our design, engineering, and teaching teams. That was also the result of our conviction that informal mathematical understanding is underrepresented in math classes and massively underrepresented in computer-based mathematics classes. We want to help students express their mathematical ideas and get feedback on those ideas, especially the ones that are informal and under development. That’s why we built sketch before multiple choice, for example. I’m stating this commitment publicly, hoping that one or more of you will help us live up to it. ITP ITP is a two-year graduate program located in the Tisch School of the Arts whose mission is to explore the imaginative use of communications technologies — how they might augment, improve, and bring delight and art into people’s lives. Perhaps the best way to describe us is as a Center for […]
I had a spreadsheet that entered blank cells when there was more than one admin for a WordPress site. So if Site_1 had two admins, I’d get two rows of data. The first row for the site would have- siteURL | siteTitle | siteAdmin but the second row for that site would have something like- < blank > | < blank > | siteAdmin I started to just drag down and fill but there was lots of data and it just felt like something for the machine to do. The following Google Script did it for me in a few seconds despite a couple thousand rows of data. Not rocket science but it might be handy for someone and it was a really convenient example of variables and loops when I had a conversation with my son last night.
How Technology Hijacks People’s Minds — from a Magician and Google’s Design Ethicist — Medium This is far more than “technology” . . . The “most empowering” menu is different than the menu that has the most choices. But when we blindly surrender to the menus we’re given, it’s easy to lose track of the difference: growth & development – gangster disciples 12. HOW MANY STEPS TO GANGSTA CITY? 63 13.

I don’t understand why they like programming. * I’m not a real programmer. I throw together things until it works then I move on. The real programmers will say “Yeah it works but you’re leaking memory everywhere. Perhaps we should fix that.” I’ll just restart Apache every 10 requests. To train future ed-tech leaders, higher ed needs new discipline, some say “The report also called for colleges to train […]

I’d add a hashtag and forward it on where a spreadsheet would parse out some stuff from the subject line based on the | character. At some point it stopped working and I never quite figured out what the issue was. I thought I wrote about it but, if I did, I can’t find it. It may be in one of my many draft posts. In any case, here’s a better and more customizable solution. It’ll grab anything I label ‘support’ and throw it in a spreadsheet with a few different chunks of information in different columns (to, from, date, subject line, link to the email). You’d open a spreadsheet and name a sheet ‘data.’ Open up the script editor (Tools>Script Editor) and put the script below in it. You might want to change the search parameters. Look at the stuff below the asterisk line. If you want to play around with the right search parameters, just practice in GMail with these parameters and then use them in the query variable below. You will want to set the trigger to run at 1-2AM each day. So now, all I have […]
I have to assume this person did this so they would be able to claim the police mis-read their license plate. This had been my plan for many years. Outside VCU’s school of education . . .
flickr photo shared by San Diego Air & Space Museum Archives with no copyright restriction (Flickr Commons) Minor Thoughts on Computational Thinking Probably obvious stuff but I’m trying to jot things down for my own reference. The first thing one ought to know about computational thinking/programming is that there are many correct paths (although some are better1 than others). This is true for just about anything but I think people think technology will be much more . . . binary. Searching for cleaner paths can be kind of fun. Computational thinking is powered by vocabulary. Vocabulary, like in language, is closely tied to concepts (maybe analogies). Having never heard of the range function, it didn’t occur to me that it existed . . . let alone that I should use it. To make it work properly I need grammar but just knowing the word exists and means something starts to change things for me. It brings to mind setting up programming challenges much more like Dan Meyer’s 3 Act math lessons . . . with the scenario really begging for the addition of a particular concept but letting students struggle with it rather than providing it ahead of time. A Path This is a little bit of real-life progression which demonstrates how one thing can be done in a variety […]
