We also discuss the Stroop Color and Word Test (try it here), crystallized versus fluid intelligence, and the dynamic systems theory of learning.

27 JAN 2020 · In this interview, Gunter Maris explains the theory behind The Wiring of Intelligence, a network model of learning. Maris describes the actions of a “crazy electrician” who wires the connections in our brains. The network theory of intelligence developed by Maris (with colleagues Alexander Savi, Maarten Marsman, and Han van der Maas) is based on the idea of a house with interconnected electrical sockets in every room that represent synaptic knowledge.

2 JAN 2020 · In this episode of ACTNext Navigator podcast, we discuss some of the history of AIG at ACT and a couple new devices: AIG for assessing graphic literacy (AIGL) and passage organizing and extraction (POE). Guests: Rick Meisner, Ian MacMillan, Brad Bolender.

21 NOV 2019 · In this episode of ACTNext Navigator podcast, we’ll go under the hood of ACT's automated essay scoring engine, CRASE+. Our guests are Erin Yao and Scott Wood. CRASE+ is a writing assessment tool that begins with human graders to develop a rubric. Data from human graders is used to train the automatic grading on a large scale.
