Welcome – About the Conference

The Psychometric Society will hold its 77th Annual Conference at The University of Nebraska–Lincoln in Lincoln, Nebraska. The conference will be held July 9th through 12th, 2012, with pre-conference workshops occurring on Monday, July 9th and the main meeting program beginning on Tuesday June 10th. The Psychometric Society was founded in 1935. It is an international nonprofit professional organization devoted to the advancement of quantitative measurement practices in psychology, education, and the social sciences. The Society publishes the journal Psychometrika, which contains articles on the development of quantitative models of psychological phenomena, as well as statistical methods and mathematical techniques for the evaluation of psychological and educational data.

The meeting is hosted by the College of Education and Human Sciences Department of Educational Psychology, a center of excellence within the University of Nebraska–Lincoln dedicated to the furtherance of knowledge and expertise in all fields of human assessment, including educational testing, psychological assessment, talent evaluation and epidemiological research.

Psychometricians from all parts of the world will take part in IMPS 2012. They will represent countries from throughout the Americas, Europe, Africa, Asia and Oceania.

Workshops

#1 Monday 7/9/12, 9:00am - 4:00pm

Psychometrics with R

Florian Wickelmaier, Eberhard Karls University - Tubingen, Germany & Hannah Frick, Innsbruck University, Austria

Format:
Full-day workshop with four sessions of 1.5–2 hours each. The two morning sessions will give an overview of R (1) in general and (2) for psychometrics in particular. The afternoon sessions are practical tutorials focusing on specific topics: (3) IRT, and (4) SEM/CFA.

Content:
(1) Introduction to R: First steps in R (installation/help/data), exploratory data analysis, linear modeling.
(2) Overview of Psychometrics with R: A tour of psychometrics packages in R, highlights from task view, small examples/demos.
(3) Item Response Modeling: Very brief review of theory, functionality of packages eRm and ltm, full case study, practical session.
(4) Structural Equation Modeling and Confirmatory Factor Analysis: Very brief review of theory, functionality of package lavaan, full case study, practical session.
#2 Monday 7/9/12, 9:00am - 4:00pm

Analyzing Large Scale Assessment Data with the General Diagnostic Model

Matthias von Davier, ETS, & Claus H. Carstensen, Otto-Friedrich-Universität, Bamberg, Germany

Full-day focused on data collected in national and international educational surveys that are hierarchically organized. Students are sampled from within schools, and schools are sampled within states or countries. Several methods of accounting for this multilevel structure have been developed for a variety of psychometric models. Examples are multilevel IRT (e.g. Fox and Glas, 2003) or hierarchical extensions of latent class analysis (Vermunt, 2003). For diagnostic classification approaches, the general diagnostic model (von Davier & Yamamoto, 2004) has been extended to a hierarchical general diagnostic model (HGDM, von Davier, 2007) based on an extension of diagnostic models to a discrete mixture model (MGDM, von Davier, 2007). In this workshop, the HGDM and a selection of recent applications to large scale assessment data will be presented. The workshop will include hands-on exercises showing how to perform scale linking, growth modeling, and analyses of differential performance on items among observed and unobserved subpopulations. Participants will receive a copy of a software program for use with the exercises. This program can be obtained free of charge for research purposes and non-commercial use.

#3 Monday 7/9/12, 9:00am - 12:00pm

Models of measurement: from an engineering point of view

Luca Mari, Università Cattaneo – LIUC, Castellanza (VA), Italy

As an information acquisition and representation experiment, measurement is today acknowledged to be more than a purely empirical process, as instead traditionally assumed. Its experimental outcome, i.e. the transducer output in the case of physical instruments, has to be interpreted as a property value, thus making the adoption of models, of both the measure and the measuring system, unavoidable although sometimes implicit.

With a systematic reference to two current background documents -- the "International vocabulary of metrology–“Basic and general concepts and associated terms" (VIM, JGCM 200:2008), and the "Evaluation of measurement data –Guide to the expression of uncertainty in measurement" (GUM, JGCM 100:2008) –the workshop will propose a state of the art overview on the role of models of and in measurement, as considered from an engineering point of view. The presentation, whose formal side is just elementary function theory, will cover topics such as standard and instrument calibration, metrological traceability, measuring system characterization is terms of precision and accuracy, measurement uncertainty.

The workshop will pave the way to a discussion on the possible analogies and synergies between the "hard" and the "soft" side of measurement.
