Scaling Procedures For Iccs Test Items, Wolfram Schulz, Julian Fraillon
Julian Fraillon
This chapter describes the procedures used to analyse and scale the International Civic and Citizenship Education Study (ICCS) international and regional test items that were administered to measure students’ civic knowledge. The chapter covers the following topics: the scaling model used to analyze and scale the test items; test coverage and item dimensionality; assessment of item fit; assessment of scorer reliabilities for open-ended items; differential item functioning by gender; review of cross-national measurement equivalence; international item adjudication; international item calibration and test reliability; international ability estimates (plausible values and weighted likelihood estimates); estimation of changes in civic content knowledge between …

Scaling Procedures For Iccs Questionnaire Items, Wolfram Schulz, Tim Friedman
Dr Wolfram Schulz
This chapter describes the procedures used to scale the International Civic and Citizenship Education Study (ICCS) questionnaire data (for students, teachers, and schools) and the indices based on them. In general, it is possible to distinguish two general types of indices derived from the ICCS questionnaires: 1. Simple indices constructed through arithmetical transformation or recoding, for example, ratios between teachers and students; and 2. Scale indices derived from scaling of items, a process typically achieved by using item response modeling of dichotomous or Likert-type items. The first part of this chapter lists the simple indices that were derived from the …

Iccs Questionnaire Development, Wolfram Schulz, Bruno Losito, David Kerr
Dr Wolfram Schulz
This chapter describes the development of the International Civic and Citizenship Education Study (ICCS) international questionnaires for students, teachers, schools, and national research centers. The student questionnaire was designed to measure both learning outcomes and contextual information. The teacher questionnaire was designed to gather teacher perspectives on the general school and community environment, teaching methods, and civic and citizenship education. School principals were asked to report on the school context for learning, on school characteristics, including school climate, as well as aspects of civic and citizenship education at their schools. An online questionnaire for national research coordinators (NRCs)—the national contexts …
