Students' difficulties with proofs are well documented. To remedy this, it is often recommended that reasoning and proving be focused on in all grades and content areas of school mathematics. However, proofs continue to have a marginal place in many classrooms, or are only given explicit attention in courses in Euclidean geometry. Geometry is also…

Internal and external factors influence teachers' daily assessment decisions. The purposes of teachers' assessments are crucial, as these purposes guide the assessment process. Still, little is known about teachers' assessment purposes. The aim of this study is to identify and describe the different purposes of assessments that Civics teachers…

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…

Cosmology concepts encompass complex spatial and temporal relations that are counterintuitive. Cosmology findings, because of their intrinsic interest, are often reported in the public domain with enthusiasm, and students come to cosmology with a range of conceptions some aligned and some at variance with the current science. This makes cosmology…

The loss of insect biodiversity is a major global sustainability issue that is highly relevant to science education. Science education can support and develop learners' competence to take actions to sustain insect biodiversity and empower learners to deal actively with this sustainability issue. However, we currently lack an instrument to assess…

The factor structure of the measure of school engagement 'Engagement Versus Disaffection with Learning: Teacher Report' was investigated in the sample of 360 Swedish 6th graders. Confirmatory factor analyses showed no support for the suggested four-factor structure including behavioural engagement, emotional engagement, behavioural disaffection…

This article nuances an ongoing discussion among researchers about external researchers in emancipatory action research in the educational field. It examines opportunities and challenges for emancipatory action research for participants in top-down and bottom-up initiated action research projects with external researchers. An analysis based on…

This study aims to assess student motivation to provide valid responses to the PISA student questionnaire. This was done by modeling response times using a three-component finite mixture model, comprising two satisficing response styles (rapid and idle) and one optimizing response style. Each participant's motivation was operationalized as their…

Despite the central role of proofs in mathematics, research often shows that school textbooks offer limited support for the teaching and learning of proof-related reasoning. This study contributes to this field of research by studying Swedish and Finnish upper secondary textbooks on logarithms and combinatorics. Justifications in expository…

The purpose of this paper is to follow the reasoning of high school students when asked to explain the standard trigonometric limit lim/[theta][right arrow] sin[theta]/[theta]. An observational study was conducted in four different phases in order to investigate if visualization, by means of an interactive technology environment (Geogebra), can…

Evaluating knowledge and learning in psychotherapy is a growing field of research. Studies that develop and evaluate valid tests are lacking, however. Here, in the context of internet-based cognitive behavioral therapy (ICBT) for adolescents, a new test was developed using subject matter experts, consensus among researchers, self-reports by…

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…

In many countries' policy documents and curricula, teachers in the subject areas of science, social science and language are encouraged to collaborate on cross-curricular issues such as sustainable development (SD). This study is conducted in secondary schools (compulsory years 7-9) in Sweden and investigates the similarities and differences in…

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…
