Computer-based assessments is becoming more and more common in mathematics education, and because the digital media entails other demands than paper-based tests, potential threats against validity must be considered. In this study we investigate how preparatory instructions and digital familiarity, may be of importance for test validity. 77 lower…

International large-scale assessments (ILSAs) have become an important part of the Swedish evaluation system. It is therefore of crucial importance to validate national measures of Swedish students' achievement with their ILSA test scores. Here, we offer results from such a validation study based on Swedish students' test scores in IEA's Trends in…

Although students' perceived learning is central in physical education (PE), few measurements are available. Furthermore, little is known about how students' perceptions of PE effect students' perceived learning in PE. Therefore, the aim was to develop a scale to assess students' perceived learning and a measurement to assess students' perceived…

Reading comprehension is often treated as a multidimensional construct. In many reading tests, items are distributed over reading process categories to represent the subskills expected to constitute comprehension. This study explores (a) the extent to which specified subskills of reading comprehension tests are conceptually conceivable to…

Previous studies indicate that school climate is important for student health and academic achievement. This study concerns the validity and reliability of the student edition a Swedish instrument for measuring pedagogical and social school climate (PESOC). Data were collected from 5,745 students at 97 Swedish secondary schools. Multilevel…

This study presents the development process and initial validation of the NyTid test, a process-oriented movement assessment tool for compulsory school pupils. A sample of 1,260 (627 girls and 633 boys; mean age of 14.39) Swedish school children participated in the study. In the first step, exploratory factor analyses (EFAs) were performed in…

The purpose of the study was to investigate how grading in primary school affected students' achievement measured by grades in 7th, 8th and 9th Grade and educational attainment in upper secondary school (12th Grade), and how the effect varied as a function of students' cognitive ability, gender and socio-economic status. The data derived from the…

Research has found that grades are the most valid instruments for predicting educational success. Why grades have better predictive validity than, for example, standardized tests is not yet fully understood. One possible explanation is that grades reflect not only subject-specific knowledge and skills but also individual differences in other…
