Article
Strategy use in single-digit addition is an indicator of young children’s numeracy comprehension. We investigated Danish primary students’ use of strategies in single-digit addition with interview-based assessment of how they solved 36 specific single-digit addition problems, categorized as either ‘error’, ‘counting’, ‘direct retrieval’ or ‘derived...
Conference Paper
Full-text available
In this paper, we aim to quantify students' development of mental strategies in single-digit addition over a five months period in six Danish year one classes dependent on their initial stage based on assessment interviews of 83 year one students' strategy use when answering 36 single-digit addition tasks. Students were interviewed twice (autumn an...

Acknowledging evidence that the ability to estimate has major consequences for both later mathematics learning and real-world functionality, this paper examines the national mathematics curriculum for compulsory school for each of Denmark, Norway and Sweden for the estimation-related opportunities it offers children. Framed against four conceptuall...
Article
Full-text available
The aim of this longitudinal study was to examine the differences between high-and low-performing students' development of fraction proficiency over a school year and to investigate how those differences were related to instruction in fractions versus instruction in other mathematics topics. The data for this study were drawn from a group of (n ¼ 3...

Computational estimation, typically construed as an approximate mental calculation of an arithmetical problem, is an important skill in everyday life and a wide range of professional contexts. Despite its importance, textbooks and curricula address it inadequately, with the consequence that many teachers are uncertain as to why and how they should...
Conference Paper
Full-text available
This study investigates Danish teachers' perspectives on teaching and learning number and addition in year one through analyses of semi-structured interviews with six year one teachers. The teachers' perspectives are compared with theories on foundations for learning number and addition. The analysis indicates that important foundational factors, e...
Article
DK: Regnestrategier har betydning for elevens udvikling i matematik gennem hele skoleforløbet. Regnestrategier er en indikator for tal- og regneforståelse, og der er en veldokumenteret sammenhæng med udpræget brug af tællestrategier og risiko for senere matematikvanskeligheder. I denne artikel afdækker jeg begrebet regnestrategier og kommer med eks...
Article
Blokmodellen er en visuel model, der anvendes i problemløsning, bl.a. til at hjælpe eleverne med at genkende regneart. Visualiseringer anvendes i matematikundervisning som redskab, eller repræsentationsmodel, til at understøtte udvikling af begrebsforståelse og problemløsningsprocesser. Med udgangspunkt i Bruners repræsentationsformer (konkret, vis...
Thesis
This dissertation addresses students’ use and development of mental strategies in single-digit addition in the first years of school in Denmark. The overarching aim was to investigate longitudinal and cross-sectional patterns in Danish students’ development and use of strategies for single-digit addition in relation to 1) different teaching practic...
Chapter
The Nordic countries are admired internationally for their well-developed policies on social inclusion within equitable social and educational systems. But we know very little how equally the children who have learning difficulties in mathematics are identified and provided support. The aim of this chapter is to describe and compare the identificat...
Conference Paper
Full-text available
In this paper we present an investigation of six Danish teachers' expectations for their first grade students within the subject addition. We asked the teachers what the students should know by the end of grade one. A constant comparison analysis revealed three themes: curriculum objectives, mathematical content, and differentiation. The teachers'...

I forbindelse med eksamener baseret på multiple choice-tests er der en mulighed for at opnå et forudsigeligt antal rigtige svar ved hjælp af gætning alene. I forbindelse med kriteriebaseret karaktergivning (karaktergivning baseret på læringsmål) er det derfor nødvendigt at tage højde for at eksaminander systematisk vil svare rigtigt på et højere an...

According to Encyclopedia on Early Childhood Development early detection of constrained arithmetic comprehension is important to prevent development of severe mathematical difficulties (Jordan, 2010). For that purpose, efficient diagnostic tools are suitable. In this paper we evaluate two tests with different approaches to diagnosing mathematical d...

Kan babyer regne? Kan en løve tælle? Eller en Krage? Har vi en medfødt fornemmelse for tal? Og hvad betyder det for matematikundervisningen? I denne artikel vil vi give en oversigt over den neurovidenskabelige viden om, hvordan tal og matematik opfattes og udvikles i hjernen. Meget af denne viden baseres på den franske forsker Dehaene’s arbejde. Ha...
Conference Paper

We are developing a diagnostic test aimed at revealing the extent to which a child demonstrates fundamental insight in arithmetic principles based on the level of sophistication of the strategies used in solving basic addition facts. Strategy choice in arithmetic is a powerful and simple parameter in screening for mathematical difficulties because...
Article
Flora and vegetation of ancient forests differ from that of new forests. Former agricultural use is still detectable in the composition of the flora centuries after new forests are established. The reason for the very slow migration of some forest species has been discussed and it has been suggested that establishment of ancient forest species in n...
Article
This study compared the vegetation and soils of forest stands with different land-use histories in a major forest complex with new forest stands isolated from ancient forests. Vegetation did not vary significantly in relation to former land-use within the major forest complex, but was significantly different between the major forest complex and the...

The distribution of the flora with different species attributes are investigated in two studies of forest ecosystems in Denmark, One study compared 17 forests with different degrees of management, the other study compared the flora of 25 old forests with that of 6 new forests. No effect of forest management could be detected in the distribution of...
