The Reporting Of Icils Results, Wolfram Schulz
The Reporting Of Icils Results, Wolfram Schulz
Dr Wolfram Schulz
This chapter describes the procedures that were used to report the population estimates in the ICILS 2013 publications. It starts with a description of the replication methodology used to estimate sampling variance, followed by an outline of how the imputation variance of students’ computer and information literacy (CIL) was computed. The subsequent section outlines the procedures for conducting significance tests of differences between country and subsample means or percentages.

International Computer And Information Literacy Study: Assessment Framework, Julian Fraillon, Wolfram Schulz, John Ainley
Dr Wolfram Schulz
The purpose of the International Computer and Information Literacy Study 2013 (ICILS 2013) is to investigate, in a range of countries, the ways in which young people are developing computer and information literacy (CIL) to support their capacity to participate in the digital age. To achieve this aim, the study will assess student achievement through an authentic computer-based assessment of CIL administered to students in their eighth year of schooling. It will also collect and report on analyses of data about student use of computers and other digital devices as well as students’ attitudes toward the use of computers and …
Scaling Procedures For Icils Questionnaire Items, Wolfram Schulz, Tim Friedman
Scaling Procedures For Icils Questionnaire Items, Wolfram Schulz, Tim Friedman
Dr Wolfram Schulz
This chapter describes the procedures used to scale the ICILS questionnaire data (for students, teachers, school principals, and ICT coordinators) and the indices based on them. Two general types of indices could be distinguished, both of which derived from the ICILS questionnaires: 1. Simple indices constructed through arithmetical transformation or simple recoding, for example, ratios between ICT and students or an index of immigration background based on information about the country of birth of students and their parents; and 2. Scale indices derived from scaling of items, a process typically achieved by using item response modeling of dichotomous or Likert-type …
