Over the years, there have been various calls to increase and better represent astronomy in curricula. This is motivated by views within the astronomy and astronomy education communities that the awe, wonder, and interdisciplinary nature of astronomy has the potential to engage students in STEM across disciplines. Reviews of curricula have shown…

Take a selection of balls and marbles along to a nearby playground slide and let students investigate factors that may influence how balls accelerate down an inclined plane. Students can make hypotheses in small groups, plan investigations to test multiple possible explanations and draw conclusions about the importance of different variables. The…

This paper examines the affordances of physical objects (e.g. apparatus, models, manipulatives) as they were used by teachers and students to make meaning in coordination with their speech and gestures. Despite the pervasive use of physical objects as material and tactile resources in hands-on investigations or demonstrations, there have been few…

This study explores the form of curriculum documents and its implications for the enacted curriculum. In this study, the narrative voices that appear in the Scottish Broad General Education phase and the Swedish Compulsory phase of the curriculum are scrutinized in relation to the most likely reader of these documents--the teacher. The study…

This open access book presents original research on effective and equitable teacher practice in mathematics and science education across Nordic countries. It focuses on three key aspects of teacher practice: what teachers teach, how teachers teach, and how teachers assess their students. To provide a comprehensive understanding of teacher…

In the educational literature on peer effects, attention has been brought to the fact that the mechanisms creating peer effects are still to a large extent hidden in obscurity. The hypothesis in the study reported in this article was that the Frame Factor Theory (FFT) can be used to reveal such mechanisms. Using data from the Swedish TIMSS 2015 (N…

This study examined how high school students' attitudes toward advanced physics were predicted by their sense of school belonging, and how gender moderated this relationship. The Trends in International Math and Science (TIMSS) 2015 Advanced data, consisting of responses from 12th grade students enrolled in advanced physics courses among nine…

Classrooms with higher teaching quality were associated with higher learning outcomes in mathematics and science. Classrooms where teachers reported high degrees of limitations to teaching in the classroom--including disruptive students or students with language barriers--were associated with lower learning outcomes. These are two of the important…

The study aimed to determine the extent of associations of physics, mathematics, and between physics and mathematics based on the results of the 2007, 2011, and 2015 Trends in Mathematics and Science Survey achievement tests. Utilizing educational data mining and correlational data analysis (significance set at [alpha] = 0.05), this study's…

This case study investigates, at three Swedish schools, primary school students' knowledge of the equal sign. The schools were chosen as representatives of schools whose students have different socioeconomic backgrounds. The data consist of Grade 3 and 6 students' responses to an assessment form based on Matthews et al. ("JRME,"…

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…

The purpose of this study was to identify international trends in K-12 computer science curricula in countries that have introduced computer science education. Content analysis method was used to analyse the country-wide curricula of 10 countries which have introduced computer science education at the primary level. The K-12 Computer Science…

One strand of comparative didactics aims at discussing the relationships between the theoretical constructions developed within subject didactics and how these can contribute to research about teaching and learning. This article explores the relationships between categories for analysing joint actions of teacher and students (didactic contract,…

According to the curricula in various countries, teachers in the subject areas of science, social science and language are often expected to collaborate on cross-curricular issues such as sustainable development (SD) in the 9-year compulsory school. This study is based in Sweden and investigates teachers' teaching traditions. The overall aim of…

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…
