Currently I am the director of the College of Social Sciences, FMG.
Between 2004 and 2021, I ...
My research used to focus on quantitative measurement in psychology. In recent years my interests have shifted to experimental research on the effectiveness of educational interventions.
Courses I taught include Methods and Statistics in Educational Sciences in the CDES research master and 'Toegepaste Methodenleer en Statistiek' or TMLS, a second year bachelor course on research methods and statistics. I also coordinated the 'OnderzoeksPracticum'. The MOOCs Quantitative Research Methods and Inferential Statistics are based on the undergraduate courses I taught on research methods and inferential statistics.
I currently serve on the following boards: DLO, FMG financiele commissie, Doorontwikkeling REC.
Previously, I served on others boards, including the Blended Learning and later the Centre for Learning and Teaching board from 2015 - 2018. Other professional activities include conference organization and website work for the Society for Mathematical Psychology, and helping to set up the Women of MathPsych workgroup. I chaired UvAPro, the PhD student association of the UvA.
In de cursus Toetsende Statistiek, de vierde cursus in het M&T programma, worden basistechnieken uit de inferentiële, of toetsende statistiek behandeld. We beginnen met de basisbegrippen waaronder statistische hypothesen, toetsingsgrootheidverdelingen, overschrijdingskansen, power en type I en II fouten. Naast deze algemene begrippen komen een groot aantal specifieke statistische toetsen aan bod, waaronder z-toetsen voor 1 en 2 proporties, McNemars toets voor afhankelijke proporties, t-toetsen voor 1 gemiddelde (van gepaarde verschillen) en 2 gemiddelden, de Chi-kwadraat toets voor onafhankelijkheid, Fisher’s exacte toets, enkelvoudig regressie (lineair, exponentieel en logistisch) en multipele regressie, eenweg- en meerweg-variantie-analyse (between subjects) en de non-parametrische toetsen van Wilcoxon, Kruskal-Wallis en de tekentoets en rangtekentoets. Het toepassen van deze technieken met behulp van statistische software (SPSS) wordt geoefend in speciale practica.
Het verwerken van academische literatuur wordt geoefend door middel van schrijfopdrachten die worden besproken in werkgroepverband. Het begrijpen en interpreteren van onderzoeksliteratuur zal worden geoefend via het schrijven van samenvattingen en korte papers. Het zelf rapporteren van nieuwe onderzoeksresultaten zal worden geoefend middels het schrijven van een resultaten- en discussie-sectie van een onderzoeksverslag.
Knowledge of (a) the most commonly used statistical (GLM) techniques in educational research; (b) how to apply these techniques to real data sets with the computer program SPSS; (c) how to report statistical analyses and the results in academic journals; (d) how to read, understand, and interpret academic journal articles in which the techniques are used.
The course starts with a short review of common experimental and quasi-experimental research designs, and associated types of analysis of variance (ANOVA). The general linear model is introduced as the general model that subsumes both ANOVA and regression analysis. Multiple regression analysis and MANOVA are treated extensively. Next, the generalised linear model is introduced as the even more general model that also subsumes logistic regression analysis and log linear modelling, which techniques are also treated extensively. Effect size indices and statistical power will be discussed for all mentioned statistical techniques. Through practical assignments, students not only learn how to apply the statistical techniques, but also how to prepare and screen data, and how to handle commonly encountered problems such as missing values, outliers, non-normality, heteroscedasticy, multicollineraty, inflated family-wise error rates, etc. Articles from educational research journals are used to illustrate how the statistical techniques are applied and described in the scientific literature, and how the results can be reported and interpreted.
Students learned how to create a webapplication that allows the administration of a psychological test or survey online.
During the course students mastered:
This course is no longer offered.
I coordinated this course and taught the section on measurement. Here we considered what constitutes measurement, discussed several theories of measurement and the restrictions that measurement assumptions put on the use of statistical tests.
