Workshop: Learning Analytics Building Bridges between the Education and the Computing communities

This workshop is the second edition of LABBEC. It aims to foster insemination between the field of education measurements and education practitioners, and the EDM community. Research contributions will be invited on topics related to the mutual influence between EDM and the education community. Demos of real world applications issued from EDM are expected and a discussion in the form of a roud-table is planned.

2019 International Measurement Confederation (IMEKO) Joint Symposium

Mark Wilson and I would like to alert everyone to the 2019 International Measurement Confederation (IMEKO) Joint Symposium to be held 2-5 July in St. Petersburg, Russia. The deadline for extended abstract submissions is 15 November (
Of special interest at this Joint Symposium is the addition of IMEKO’s Technical Committee (TC) 18 on Measurement of Human Functions. The inclusion of TC18 provides a broader forum for psychological and social measurement theory and practice than was previously afforded by the areas covered by TC1 on  Education and Training in Measurement and Instrumentation, TC7 on Measurement Science, and TC13 on Measurements in Biology and Medicine. TC18 will be an important setting for sharing ideas and methods as national metrology institutes around the world commence new investigations into the viability, feasibility, and desirability of metrological standards for measurements in education, health care, human resources, social services, economics, and many other areas.
The IMEKO World Congress in Belfast, Ireland, last month included a special session highlighting measurement theory and practice in psychology and the social sciences. The session was organized and chaired by Mark Wilson and myself, with presented papers authored by David Andrich, Stefan Cano, Robert Cavanagh, Thomas Salzberger, Andrew Maul, and others. Additional talks featuring Rasch models were co-authored by Emily Oon, Jan Morrison, and Maureen Powers.
In a sign of IMEKO’s strong support for measurement innovations across the sciences, Powers’ poster on a multi-unidimensional psychophysical Rasch model of functional binocular vision was recognized with a special award at the gala dinner in the Titanic museum in Belfast.
With over ten years of Rasch-related presentations at IMEKO meetings, and steadily increasing visibility and participation, a new dialogue between the natural and social sciences is plainly gaining momentum. Looking forward to seeing you all in St. Petersburg!

GRIÉMÉtic’s conference: Response styles and aberrant responding in survey data

By Carl Falk, professor at McGill University

November 28, 2018, from 12h to 13h

Université de Montréal, Pavillon Marie-Victorin, room A-544


Online (live):


Abstract: The use of Likert-type items is pervasive throughout the social and behavioral sciences (e.g., rate your agreement to a statement on a scale from 0 – Disagree to 4 – Agree). However, individuals sometimes perceive and use the scale in different ways. In this talk, I present an item response theory model capable of modeling multiple response styles across multiple constructs of interest. Some features of this model include the ability for researchers to: 1) Flexibly determine how response styles are defined, 2) Test whether modeling particular response styles improves model fit, 3) Obtain scores for participants on the constructs of interest and response styles, and 4) Test for group differences in the response styles or substantive constructs. Comparisons with sum score-based approaches, and recent extensions to multilevel data will be briefly presented. Time permitting, additional challenges in aberrant (atypical) responding to survey items will be discussed.

Biography: Carl F. Falk is an assistant professor of Quantitative Psychology and Modeling in the Department of Psychology at McGill University. His work focuses on the development, testing, and computer programming of advanced latent variable models with applications across the social sciences (e.g., psychology, education, health outcomes, sociology, etc.). This work spans across item response theory, structural equation modeling, and multilevel modeling. Recent applied work includes analysis of field test data and simulation based evaluations of item banks for the Smarter Balanced Assessment Consortium.

Here are the slides of the presentation.

All of our conferences are free and there is no need to register.
