The purpose of the present paper is to critically examine causal inferences and internal validity as defined by Campbell and co-workers. Several arguments are given against their counterfactual effect definition, and this effect definition should be considered inadequate for causal research in general. Moreover, their defined independence between…

Nationally and internationally equity in education has become a key goal. In Norway, a White Paper has been tabled to address how equity can be improved through education. In this paper the pedagogic and knowledge orientation of the initiatives are analyzed and discussed in relation to two models of equity: "equity through equality" and "equity…

We describe the effects of an intervention designed to develop the mathematical word problem solving of low-achievers. The eight students participating in the intervention were selected from 429 10-year-olds on the basis of their difficulties in word problem solving. In the intervention, we combined intensive, systematic, and explicit teacher…

Grades are important for admission of students in most higher education programs. Analyzing admission and student performance data at a major Norwegian business school, we find that the grading practice of teachers at regional colleges sending students to the school is affected by the average performance of the students being graded. Teachers at…

The aim of the present study was to investigate children's achievement goal orientations and their relations to math achievement in the primary grades. The sample consisted of 179 children who were in the 2nd and 3rd grades during the first measurement and in the 3rd and 4th grades during the second measurement. Children's self-ratings were…

The dynamic model of educational effectiveness defines school level factors associated with student outcomes. Emphasis is given to the two main aspects of policy, evaluation, and improvement in schools which affect quality of teaching and learning at both the level of teachers and students: a) teaching and b) school learning environment. Five…

Four validation studies of different versions of the Approaches to Studying Inventory (ASI) were performed by means of exploratory and confirmatory factor analysis. Six samples of undergraduate students participated (N = 4,038), drawn from different bachelor programs in selected university college departments. The results gave limited support to…

We prospectively examined the role of physical activity involvement, weight status, and motor functioning capability in 1st grade for social status among other pupils in class in the 4th grade. Our sample included 80 Norwegian 1st grade pupils (Girls N = 44; Boys N = 36). 1st grade motor proficiency and objectively measured physical activity, but…

What influence does the teacher exercise over their students' learning outcomes? This study investigates the impact of teacher quality on student learning outcomes in science halfway through the first year of high school. A multiple-measurement model estimates the potential impact of teacher influence on learning outcomes for 1,060 secondary…

This article focuses on a cooperating teacher in Norway and her approach to mentoring first-year student teachers in their process of planning the mathematics teaching of third-graders. The purpose of the text is to show how the cooperating teacher's mentoring assists the student teachers' performance in a teaching form that is acknowledged as…

According to the Simple View of Reading (SVR), reading comprehension is the product of word decoding ability and linguistic comprehension (R = D x C). However, there is also evidence showing that an additive model (R = D + C) explains just as much or even more of the variance in reading comprehension than the product model. To further evaluate…

This longitudinal research was designed to examine the prevalence and co-occurrence of peer problems such as rejection, withdrawal, loneliness, bullying, and victimization experienced by children (99 boys, 80 girls) in their everyday lives at daycare, in preschool and first grade of school--each successive spring--at the ages of 5, 6, and 7.…

This is a study of schools as professional learning communities, defined by nine characteristics and their relationship with the schools' level of effectiveness.
