CPS X ‘Crisis in Space’

CPS X or “Crisis in Space” is a two-player game that focuses on collaborative problem solving (CPS), one of the cross-cutting capabilities that are part of ACT’s Holistic Framework. Players work together to achieve group goals that require high levels of leadership, coordination, information sharing, and rapid responses to novel situations.  The digital collaborative assessment measures behaviors indicative […]

WorldCanvass Podcast Featuring ACTNext Sr. Research Scientist Yuchi Huang

“It’s news to very few of us that artificial intelligence (AI) is no longer only in the realm of science fiction—it’s all around us. But what is it? From disembodied communication partners like Siri and Alexa to targeted marketing, intelligent vehicles, advanced medical diagnostics, and deepening layers of social media analytics, AI is changing the […]

Making “It’s All About the Data” a Reality in Education

In today’s schools, hardly a day passes when educators from the classroom to the superintendent’s office don’t hear the phrase, “It’s all about the data.” But what does that truly mean for learning and teaching and what impact can access to the vast amount of data available to educators have on linking student assessment to […]

Response times in educational assessment: Moving beyond traditional assumptions

Abstract: With the increasing popularity of computerised testing, in many applications of educational testing not only the accuracy of the response is recorded, but response time as well. This additional information provides a more complex picture of the response processes. The two most important reasons to consider response times are: 1) to increase precision of […]

Urnings: Nextgen psychometrics tools for nextgen learning and assessment systems

Abstract: The Urnings rating system is an algorithm for tracking changes in ability and item difficulty in real time. When in equilibrium, the estimates are unbiased and their measurement error is known, which makes the system suitable for high-stakes testing. Furthermore, it is computationally very efficient, which makes it suitable for large-scale applications. The Urnings […]
