Judith Conijn

Postdoctoral researcher

Position

Judith Conijn is a postdoctoral researcher of Educational Science at the Faculty of Behavioural and Movement Sciences of Vrije Universiteit Amsterdam, The Netherlands.

Biography

I was born and raised in Amstelveen, a town near Amsterdam, but I’ve always also spent much time in the countryside of Finland. I obtained my research master’s degree in psychological methods at the University of Amsterdam and conducted my Phd project at Tilburg University. The Phd project concerned detecting and explaining aberrant response patterns in questionnaire data. After receiving my Phd, I worked as a lecturer at the clinical psychology department of the Leiden University and as a postdoc at the methods and statistics group of the Institute of Child Development and Education of the University of Amsterdam. My interest in educational research originally comes from observing the large differences between the educational systems of The Netherlands and Finland and has further increased while working at the UvA. I feel very fortunate that I can now combine my methodological knowledge with my educational interests in the wonder-full education project.

Areas of expertise

Wonder-full education, self-report data quality, psychometrics, research methodology

Research

In the past years, I’ve been working on statistical methods for detecting aberrant responding to self-report questionnaires, the correspondence between self and informant reports of personality and psychopathology, and the validity of young children’s self-reports.

Within the wonderful education project, I’m involved in developing and validating the Wonderful Education Questionnaire (project 4) and testing the main research question (project 6): does wonder-full education have a positive effect on human flourishment in children? My other educational research interests are the effects of teacher-pupil relationships on learning outcomes and the social-emotional effects of different types of primary education systems in children.
