Hello world. For all progress in our project @ImprovingILSA, follow us through our website https://t.co/JoTVFGiYJf

Convenience sampling can introduce systematic bias into the estimates in simulation.

An example is demonstrated in this blogpost by generating a background questionnaire and cognitive response in lsasim and then fitting latent regression model in TAM.

A new blog post outlines how you can obtain comparable item parameter estimates in PARSCALE, mirt, and TAM for two-parameter IRT model. And, specifying item parameters for lsasim.

"No one likes a bully: How systematic is international bullying in fourth grade?" say @lrutkowski and @DRutkowski_EDU at the symposium on IEA Compass: Briefs in Education series #IEAIRC.

"Is democracy overrated? Latin American students’ support for dictatorships" a presentation by @ImprovingILSA partner @asandovalh from the University of Bath at the symposium on IEA Compass: Briefs in Education series #IEAIRC

[IEA - Education @iea_education]

Thanks to our international panel from Chile, Croatia, Denmark and Italy for their interesting #ICCS perspectives at #IEAIRC https://t.co/rTf7YJGT9S

[Improving ILSA @ImprovingILSA]

Last presentation at the symposium entitled, "On test taking motivation in MST" presented by @ylindaliaw (with @lrutkowski and @davidru as co-authors).

[David Rutkowski @DRutkowski_EDU]

@lrutkowski and Dubravka Svetina giving a nice presentation @iea_education #IEAIRC on MST designs in ILSAs

[Ernesto Treviño @treviner]

@lrutkowski presenting about multistage testing and the future of international education assessments #IEAIRC @iea_education

[Improving ILSA @ImprovingILSA]

The next presentation at the sympsium is enttled, "Differential item functioning in MST" by Montesrrat Valdivia, @lrutkowski and @DRutkowski_EDU

[Improving ILSA @ImprovingILSA]

Item parameter desirable properties - higher slopes are always better?, asks Dubravka Svetina in her presentation entitled, "Module length and routing methods in MST."

[Improving ILSA @ImprovingILSA]

First paper presented was entitled, "Parameter estimation stability and probabilistic routing in MST" by @lrutkowski and @DRutkowski_EDU

[Improving ILSA @ImprovingILSA]

Join the @ImprovingILSA team as they give their symposium, "The future of international assessment? The promise and challenge of a multistage design in IEA studies" at @iea_education IRC 2019.

[Improving ILSA @ImprovingILSA]

An article by @lrutkowski, Svetina & @ylindaliaw provides evidence of artifactual fit improvement, pointing to the possibility of data dredging for improved model-data consistency in challenging invariance contexts with large numbers of groups.

Tyler Matta, @lrutkowski, @DRutkowski_EDU, @lindaliawww present an article that provides an overview of the R package 'lsasim', designed to facilitate the generation of data that mimics a large scale assessment context.

"...ILSAs are—and should be—here to stay. They can serve as powerful instruments of change, although the nature and extent of their influence varies by country and over time" - Singer & Braun (2018). Read article here: https://t.co/oo3iAUW5Wt
