Our Common Online Data Analysis Platform (CODAP) software provides an easy-to-use web-based data analysis tool, geared toward middle and high school students, and aimed at teachers and curriculum developers. CODAP is already full of amazing features. We’re excited to announce several new features!
Our Common Online Data Analysis Platform (CODAP) offers easy-to-use web-based software that makes it possible for students in grades 6 through college to visualize, analyze, and ultimately learn from data. Whether the source of data is a game, a map, an experiment, or a simulation, CODAP provides an immersive, exploratory experience with dynamically linked data […]
Interactive science (Image credit: Franco Landriscina)If future historians were to write a book about the most important contributions of technology to improving science education, it would be hard for them to skip computer modeling and simulation.Much…
Recently we found that our Lab framework caused the JavascriptCore of Safari 5.1 to crash. Safari 5.1 is the latest version available for OS X 10.6. If you have OS X 10.7 or 10.8, then you have Safari 6 which doesn’t have this problem. Too long; didn’t read solution: do not name your getters the […]
The Firefox performance regression introduced into the codebase on 2012-09-29 and present in FF v18, v19, and Nightly versions is much more serious than I previously thought. Basically FF versions after v16 are now almost unusable running NextGen models of any complexity for longer than 30s. See: Firefox Performance Comparison 20131902 and Confirmation of FF […]
I wanted to see if we could roughly log how long users are spending waiting for learner data uploads. The more accurate way to do this is on the client side. However I wanted to try it on the server side so it could be applied in many cases without needing instrumented clients that send […]
[Editor’s note: Vaibhav Ahlawat was a Google Summer of Code 2012 student at the Concord Consortium.] At any time, the Concord Consortium runs a number of small research projects and large scale-up projects, but in the past we built each system separately and each required a separate login. Want to teach your fourth graders about […]
It takes a lot of computation to model the atomic and molecular world! Fortunately, modern Web browsers have 10 times the computational capacity and speed compared with just 18 months ago. (That’s even faster than Moore’s Law!) We’re now taking advantage of HTML5 plus JavaScript to rebuild Molecular Workbench models to run on anything with […]
The opposite of Thomas Dolby I was terrible at the first four weeks of organic chemistry. I just couldn’t get the right pictures into my head. The depictions of the chemical reaction mechanisms I was supposed to memorize seemed like just so many Cs (and Hs and Os and, alarmingly, Fs) laid out randomly as […]
This post describes an older method for connecting sensors to a web browser. You can learn about a newer, more robust method using Web Bluetooth in this Under the Hood article from our fall 2017 @Concord newsletter. Here at the Concord Consortium we are very interested in making sensors that are easy to use in […]
