The authors present the methodological background to and underlying research design of an ongoing research project on the scientific evaluation of serious games and/or computer-based simulation games (SGs) for advanced learning. The main research questions are: (1) what are the requirements and design principles for a comprehensive social…

Having a well-founded insight into the characteristics of teachers inquiry-based attitude (IA) supports operationalising IA as a learning goal in teacher education (TE). The aim of this study is to refine the notion of IA from an ill-defined global concept into something with reliable and valid characteristics. To do so, data were gathered on…

A network conceptualization might contribute to understanding the occurrence and interacting nature of behavioral traits in the autism realm. Networks were constructed based on correlations of item scores of the Autism Diagnostic Observation Schedule for Modules 1, 2 and 3 obtained for a group of 477 Dutch individuals with developmental disorders.…

We need methods to measure friendship among very young children to study the beginnings of friendship and the impact of experiences with friendship for later development. This article presents an overview of methods for measuring very young children's friendships. A behavioural sociometric method was constructed to study degrees of friendship…

The committees for the current Dutch context-based innovation in secondary science education employed teachers to design context-based curriculum materials. A study on the learning of science teachers in design teams for context-based curriculum materials is presented in this paper. In a correlation study, teachers with (n = 5 and 840 students)…

This paper presents a hierarchical Bayes circumplex model for ordinal ratings data. The circumplex model was proposed to represent the circular ordering of items in psychological testing by imposing inequalities on the correlations of the items. We provide a specification of the circumplex, propose identifying constraints and conjugate priors for…

Accelerated longitudinal analyses of 7 cohorts of Dutch children over a 10-year period were used to determine whether longitudinal data on children in 1 cohort could predict outcomes of psychopathology in another. Results support accelerated longitudinal analysis to combine short-term longitudinal studies of behavioral-emotional problems into a…

A technique is presented to transform incomplete categorical data into complete data by imputing appropriate scores into missing cells. A solution of the optimization problem is suggested, and relevant psychometric theory is discussed. The average correlation should be at least 0.50 before the method becomes practical. (SLD)

Mail survey, telephone survey, and keeping time were compared as methods of assessing teaching time for 74 sixth grade teachers teaching language in the Netherlands. Results suggest that each of the three methods can be used to assess the mean total score, but none can assess individual scores. (SLD)

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
