In this study, we compare Finnish and Norwegian textbook series. The results indicate that both textbook series largely facilitate skill efficiency, and most tasks are low cognitive demand. However, the Finnish textbook series facilitate conceptual understanding to a greater degree. The Finnish textbook series also introduce and develop connections between a greater number of mathematical ideas, and there is a greater number and proportion of high cognitive demand tasks in the Finnish textbooks.</p> 2025-02-13T00:00:00+01:00 Copyright (c) 2025 Per Øystein Haavold, Ane Storaas, Marthe Johnsen, Kristoffer Strand, Carina Heimstad https://tidsskrift.dk/NOMAD/article/view/152931 Preparing prospective primary school teachers in teaching informal statistical inference 2025-01-21T15:22:46+01:00 Per Blomberg per.blomberg@mau.se <p class="p1">In recent decades, the statistics education community has focused extensively on research aimed at modernising mathematics curricula by integrating powerful statistical concepts relevant to the 21st century. As a result, the professional development needs of statistics teachers are evolving. There is an increasing demand for teachers to be well-equipped to teach foundational statistical concepts, including inferential statistics, and gaining these insights has become essential. This paper presents findings from an educational design research study conducted with participants in primary teacher education. The study outlines a design principle with three sub-components, intended to guide teacher training in statistical inference. The conclusion highlights the importance of statistical inference as a central theme in statistics education, with significant implications for school statistics and curriculum evaluation.</p> 2025-02-13T00:00:00+01:00 Copyright (c) 2025 Per Blomberg https://tidsskrift.dk/NOMAD/article/view/152932 The use of spreadsheet tools in assessment: an instrumented technique perspective 2025-01-21T15:50:21+01:00 Mattias Winnberg mattias.winnberg@su.se <p class="p1">A challenge in computer-based assessment, especially when introducing specific digital tools, is balancing mathematics assessment with students’ computer skills. This exploratory qualitative study aims to investigate aspects of student-tool-interaction, essential to consider when designing digital tools for assessment. Eight 15-year-old students worked in pairs with three digital test items employing interactive spreadsheet tools, followed by semi-structured interviews. The combined analysis of observations of students’ interactions with the items and the interviews indicates difficulties in using basic spreadsheet functions – despite their conceptual understanding of the tools. The main implications of the findings emphasize the importance of integrating digital tools into learning situations before assessment, and not taking basic tool-related techniques for granted.</p> 2025-02-13T00:00:00+01:00 Copyright (c) 2025 Mattias Winnberg
