A pedagogical model by any other name

Educational technology for personalized or adaptive learning is based on various types of pedagogical models. Google provides the following info-box and link concerning pedagogical models: As described in this paper, pedagogical models are cognitive models or theoretical constructs derived from knowledge acquisition models or views about cognition and knowledge, which form the basis for learning [...]

Thiel, Creativity, and Jobs

A colleague at sent me a an interview with Peter Thiel as I was reading about a battery less transceiver where I found a partial quote from Steve Jobs.  The original quote, which can be found at the Wall Street Journal, goes on to further agree with Mr. Thiel: Creativity is just connecting things. [...]

Making Cognitive Tutors Easier

There are (essentially) two types of e-learning systems: Cognitive tutors – which emphasize deeper problem solving skills Curriculum sequencing  – which don’t diagnose cognitive skills but adapt engagement in various ways For a good overview, see: Desmarais, Michel C., and Ryan SJ d Baker. “A review of recent advances in learner and skill modeling in [...]

Personalized e-Learning Styles

Although a bit of a stretch, this post was inspired by the following blog post, which talks about the Facebook API in terms of learning styles. If you’re interested in such things, you are probably also aware of learning record stores and things like the Tin Can API.  You need these things if you’re supporting [...]

Wiley PLUS and Quantum

I was recently pleased to come across this video showing that Quantum has done a nice job of knowledge engineering in the domain of accounting with Wiley. Most of the success of cognitive tutors has been confined to mathematics, but Quantum has an interesting history of applying knowledge-based cognitive tutoring techniques to chemistry.  In this [...]

Authoring questions for education and assessment

Thesis: the overwhelming investment in educational technology will have its highest economic and social impact in technology that directly increases the rate of learning and the amount learned, not in technology that merely provides electronic access to abundant educational resources or on-line courses.  More emphasis is needed on the cognitive skills and knowledge required to [...]

Cognitive modeling of assessment items

Look for a forthcoming post on the broader subject of personalized e-learning.  In the meantime, here’s a tip on writing good multiple choice questions: target wrong answers to diagnose misconceptions. Better approaches to adaptive education model the learning objectives that are assessed by questions such as the following from the American Academy for the Advancement [...]

Electronically enhanced learning

We are working on educational technology.  That is, technology to assist in education.  More specifically, we are developing software that helps people learn.  There are many types of such software.  We are most immediately focused on two such types. adaptive educational technology for personalized learning cognitive tutors The term “adaptive” with regard to educational technology [...]

IBM Watson in medical education

IBM recently posted this video which suggests the relevance of Watson’s capabilities to medical education. The demo uses cases such as occur on the USMLE exam and Waton’s ability to perform evidentiary reason given large bodies of text. The “reasoning paths” followed by Watson in presenting explanations or decision support material use a nice, increasingly [...]

Suggested questions: Inquire vs. Knewton

Knewton is an interesting company providing a recommendation service for adaptive learning applications.  In a recent post, Jonathon Goldman describes an algorithmic approach to generating questions.  The approach focuses on improving the manual authoring of test questions (known in the educational realm as “assessment items“).  It references work at Microsoft Research on the problem of [...]
