Abstract [en]

Dyscalculia means that the individual has difficulties in acquiring arithmetic skills (i.e. addition, subtraction, division and multiplication). Even though dyscalculia affects 1.3- 10.3% of the population there is no national guidelines how dyscalculia should be investigated (SLL, 2015). The aim of this study is to standardize two tests and identify and compare any differences between genders and ages. The study includes 128 participants between school years 4-6 in central Sweden. To be included in this study the participants should have Swedish as their native language, fulfilled the tests and written informed consent from the caregivers. In this study two tests that measure parts of arithmetic ability were used; “Written multidigit calculation” and “Arithmetic fluency”. To standardize the tests descriptive statistics was made. Analysis of variance was computed to compare potential differences between gender and grades. Sidak Post hoc test was made to analyze the differences between grades. The results of the study were that school year 4 performed lower than school year 5 and 6 (p = < .05). Further we found that girls performed lower than boys on the test “Arithmetic fluency - subtraction” (p = .01). No differences between genders were found on the other tests.

Abstract [sv]

Dyskalkyli innebär att individen har svårigheter att tillägna sig aritmetiska kunskaper (dvs. addition, subtraktion, division och multiplikation). Trots att dyskalkyli drabbar 1,3-10,3 % av befolkningen finns det idag inga nationella riktlinjer om hur det bör utredas (Stockholms läns landsting [SLL], 2015). För att bidra till mer kunskap om utredning av dyskalkyli är studiens syfte att normera testerna “Skriftlig flersiffrig kalkylering” och “Aritmetiskt flöde”. Ett annat syfte är att undersöka eventuella köns- samt åldersskillnader i mellanstadiet. Den slutgiltiga studiegruppen bestod av 128 mellanstadieelever från tre grundskolor i mellersta Sverige. Endast deltagare vars modersmål var svenska, fullföljt hela testningen samt fått skriftligt informerat samtycke från vårdnadshavare inkluderades i studien. Under testningen användes två tester som mäter delar av den aritmetiska förmågan; “Skriftlig flersiffrig kalkylering” och “Aritmetiskt flöde”. Normering för testerna togs fram genom deskriptiv analys. För att signifikanspröva eventuella skillnader mellan kön och årskurs gjordes en variansanalys. Sidak Post hoc test gjordes för att analysera skillnaderna mellan årskurserna. Studien visade att årskurs 4 presterade sämre än årskurs 5 och 6 (p = < 0,05). Vidare fann vi att flickor presterade sämre än pojkar på testet “Aritmetiskt flöde - subtraktion” (p = 0,01). Inga könsskillnader fanns på övriga deltester (p = > 0,05).
