Brown Bag Seminar: Henrik Ræder

Title: Sub-scales of numeracy from grade 5 to grade 8

Abstract: Most constructs measured by large-scale assessments are treated like unidimensional constructs. However, the constructs measured are usually broad constructs consisting of multiple aspects. While these constructs behave unidimensionally when measured for a single population, the internal structure is rarely studied across multiple grades. Drawing on data from a vertical scaling study of the Norwegian National Numeracy tests from 2018, the study presented investigates the relationship between sub-scales from grade 5 to grade 8, contrasted to sub-scale behavior in individual grades.
