This cross-national study examined students' evaluation of strategies for solving linear equations, as well as the extent to which their evaluation criteria were related to their use of strategies and/or aligned with experts' views about which strategy is the best. A total of 792 middle school and high school students from Sweden, Finland, and…

This article focuses on students' meaning-making when working with mathematics textbooks from a multimodal approach that encompasses all resources for communication, which is an under researched area. Central to this study are the designed meanings of the textbooks and the affordances discovered by students when working with the textbooks. Video…

Although group work is considered beneficial for problem solving, the listening that is needed for jointly solving mathematical problems is under-researched. In this article, the usefulness of two communication frameworks for understanding students' listening is examined, using data from an educational design research study in an upper secondary…

In the face of the global sustainability crisis, schools and teachers are called on to transform education and implement educational innovations to strengthen sustainability education. One of these innovations is 'open schooling': educational practices that involve students in identifying, exploring, and tackling real-world sustainability problems…

Learning to calculate with natural numbers by structuring seems promising but how this can be taught in a sustainable manner remains an open question. An eight-month-long intervention based on the idea of using a structural approach to addition and subtraction, and particularly bridging through ten, was implemented in four Swedish first-grade…

This study focuses on computer-based formative assessment for supporting problem solving and reasoning in mathematics. To be able to assist students who find themselves in difficulties, the software suggested descriptions - diagnoses - of the encountered difficulty the students could choose from. Thereafter, the software provided metacognitive and…

The increased emergence of digital tools in educational contexts have changed the conditions for teaching and learning which, in turn, has meant a need for the development of professional digital competence (PDC) among teachers worldwide. Simultaneously, and aligned with this, programming has become an increasingly important part of schooling in…

This article revisits and expands upon a previous phenomenographic study characterising the qualitatively different ways in which South African undergraduate physics students may experience the use of +/- signs in one-dimensional kinematics (1DK). We find the original categorisation as applicable for interpreting Swedish university-level students'…

This study focuses on the problem solving skills in technology-rich environments of teachers. PIAAC (Programme for the International Assessment of Adult Competencies) data on adults' (n = 11,294) competencies, is used to investigate how problem solving skills of teachers are associated with sociodemographic, work-related, and everyday-life related…

Concurrency is often perceived as difficult by students. One reason for this may be due to the fact that abstractions used in concurrent programs leave more situations undefined compared to sequential programs (e.g., in what order statements are executed), which makes it harder to create a proper mental model of the execution environment. Students…

This article examines how a virtual case that prepares students for practical scenario training affects police students' performance in a practical scenario training. This study included 69 Swedish police students at the Basic Training Programme for Police Officers -- 35 assigned to a virtual police case (VCASE) and 34 assigned to a conventional…

In literature, teaching for an authentic learning experience is seen as rewarding and interesting, promoting better understanding of for example sustainable development and fostering students' independence. Some upper secondary schools emphasise authentic teaching and learning on their websites, showcasing how students engage in authentic tasks.…

This study detected patterns in teacher educators' and pre-service teachers' beliefs and practices regarding the degree project. Requirements in policy documents were also considered. The analysis centred on validity, teacher cognition and grounded theory. Conversations were conducted with instructors and students at three departments for teacher…

This study aims to investigate affordances of models and modelling in design projects in technology education. To learn more about affordances when working with models and modelling, four Swedish technology teachers were interviewed using a narrative approach. Despite a small number of informants data were rich, containing detailed descriptions of…

The aim of this study is to measure the effects of teaching problem-solving strategies as an integrated part of the mathematical content prescribed by the curriculum. By implementing the designs principles developed in the previous study, we carry out a one-year-long teaching intervention in a Swedish upper secondary school. Pre- and post-tests…
