Games, modeling, and simulation technologies hold great potential for helping students learn science concepts and engage with the practices of science, and these environments often capture meaningful data about student interactions. At the same time, intelligent tutoring systems (ITS) have undergone important advancements in providing support for individual student learning. Their complex statistical user models […]
Fig. 1: The analyzed house.Energy3D already provides a set of powerful analysis tools that users can use to analyze the annual energy performance of their designs. For experts, the annual analysis tools are convenient as they can quickly evaluate their…
Camilo Vieira Mejia, a PhD student of Purdue University, recently brought our Energy3D software to a workshop, which is a part of Clubes de Ciencia — an initiative where graduate students go to Colombia and share science and engineering concepts with …
Fig.1: Annual air and ground temperatures (daily averages)A building exchanges heat not only with the outside air but also with the ground. The ground temperature depends on the location and the depth. At six meters under and deeper, the temperature re…
The Concord Consortium is proud to announce a new project funded by the National Science Foundation, “Towards virtual worlds that afford knowledge integration across project challenges and disciplines.” Principal Investigator Janet Kolodner and Co-PI Amy Pallant will explore how the design of project challenges and the contexts in which they are carried out can support […]
Download the models Although it is mostly used as an engineering tool, our Energy2D software can also be used to create simple Earth science simulations. This blog post shows some interesting results about the Hadley Cell. The Hadley Cell is an atmospheric circulation that transports energy and moisture from the equator to higher latitudes in […]
Fig. 1: IR image of a wall junction (inside) by Stefan Mayer One of the mysterious things that causes people to scratch their heads when they see an infrared picture of a room is that the junctions such as edges and corners formed by two exterior walls (or floors and roofs) often appear to be […]
The Concord Consortium is delighted to announce our new Chief Learning Scientist, Janet Kolodner. She is Regents’ Professor Emerita in Computing and Cognitive Science at the Georgia Institute of Technology, and previously was on loan to the National Science Foundation from 2010 to 2014.
Two time series and their cross-correlation functionsIn a previous post, I showed you what autocorrelation function (ACF) is and how it can be used to detect temporal patterns in student data. The ACF is the correlation of a signal with itself. We are …
Visual Process Analytics (VPA) is an online analytical processing (OLAP) program that we are developing for visualizing and analyzing student learning from complex, fine-grained process data collected by interactive learning software such as computer-a…
