To celebrate 100 years of dazzling history of crystallography, the year of 2014 has been declared by UNESCO as the International Year of Crystallography. To this date, 29 Nobel Prizes have been awarded to scientific achievements related to crystallogra…
The March issue of The Science Teacher features “A New Take on Student Lab Reports” by Ed Hazzard, which describes how students can use screencasts – digital recordings of the computer screen plus audio narration – to report on their computer-based science labs, as an alternative to written reports. This could be an exciting new tool for science teaching.
Cormac Paterson is a student at Arlington High School. We ran into him last year while conducting research in the school. He quickly mastered our Energy3D CAD software. In as short as just five class periods, he came up with three different architectur…
Figure 1: Copy data from Energy2D.Since a few users asked if the simulation data in Energy2D can be exported to other applications such as Excel, I have added a feature to the app for extracting virtual sensor data as multi-column time series data. For…
Four of the nation’s leading research institutions have been awarded a $2.9 million grant from the National Science Foundation to develop a new system of classroom assessments that aligns with the Next Generation Science Standards (NGSS).
Figure 1The International Journal of Engineering Education published our paper (“A Time Series Analysis Method for Assessing Engineering Design Processes Using a CAD Tool”) on learning analytics and educational data mining for assessing student perform…
Is your New Year’s resolution to find more interactive STEM resources that are tablet-ready? (We understand — we make similar technology-related resolutions, too!) We’ve optimized many of our browser-based interactive resources to run on popular tablets. By tuning our code, we’re able to make the power of our models available for your students! For example, […]
In the winter, a fireplace is the coziest place in the house when we need some thermal comfort. It is probably something hard to remove from our living standards and our culture (it is supposed to be the only way Santa comes into your house). But is the concept of fireplace — an ancient way […]
All educational research and assessment are based on inference from evidence. Evidence is constructed from learner data. The quality of this construction is, therefore, fundamentally important. Many educational measurements have relied on eliciting, analyzing, and interpreting students’ constructed responses to assessment questions. New types of data may engender new opportunities for improving the validity and […]
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 […]
