Enabling comparable scores across grades is of interest for policymakers to evaluate educational systems, for researchers to investigate substantive questions, and for teachers to infer student growth. This study implemented a vertical scaling design to numeracy tests given in grades 5 and 8 as part of the Norwegian national testing system. Our…

Schools in Norway are supposed to meet the ideals connected to inclusive education. The most common definition of inclusive education in Norway is multiple-oriented, meaning that inclusive education is a product of a variety of values, processes and experiences. Learning environment is a particularly central element in inclusive education. The…

The current study examined the associations between students' perceptions of classroom interactions and students' emotional and behavioral engagement. Given the nested structure of the data, multilevel analyses were employed to examine these associations. A total of 1769 Norwegian fifth to tenth graders from 100 classes and 10 schools participated…

It is well-documented that academic achievement is associated with students' self-perceptions of their academic abilities, that is, their academic self-concepts. However, low-achieving students may apply self-protective strategies to maintain a favorable academic self-concept when evaluating their academic abilities. Consequently, the relation…

Women's underrepresentation in mathematics-related careers continues to concern policymakers, economists, and educators. This study addressed the issue by examining data from two international databases, namely IEA's "Trends in International Mathematics and Science Study 2015," and the World Economic Forum's "Global Gender Gap…

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the…

Teachers' experiences and attitudes play a critical role in outdoor education. In this study, we aim to explore how 5th-10th-grade (10-15 years-old students) teachers use the natural environment in their teaching practices, with special attention to the link to sustainable development (SD). In total, 42 in-service teachers were invited to…

Using data from the international Teacher Education and Development Study: Learning to Teach Mathematics (TEDS-M), the measurement equivalence of teachers' beliefs across countries is investigated for the case of "mathematics-as-a fixed-ability". Measurement equivalence is a crucial topic in all international large-scale assessments and…

Two ways of measuring change are presented and compared: A conventional "change score", defined as the difference between scores before and after an interim period, and a process-oriented approach focusing on detailed analysis of conceptually defined response patterns. The validity of the two approaches was investigated. Vocabulary…

As more primary and secondary students worldwide seek after-school tutoring in academic subjects, concerns are being raised about whether after-school tutoring can raise average test scores without widening the variability in student performance, and whether students of certain ability levels may benefit more than others from after-school…

The school is an important setting for physical activity. The purpose of the present study was to examine the association between physical environmental characteristics and participation in daily physical activity during school breaks. Data from 130 schools and 16 471 students (Grades 4-10) in Norway were obtained in 2004 through self-administered…

Accompanying the rise in the number of working parents is a growing demand for after-school care schemes for children. After-school care schemes, in addition to school, provide pupils with more learning opportunities than the experiences that school provides. The hypothesis is that after-school care schemes offer a better knowledge-basis for…
