Abstract [sv]

Följande examensarbete är en interventions-studie med utgångspunkt i aritmetik-undervis-ning och tals del-helhetsrelationer. Vissa fors-kare menar att del-helhetsrelationer är en grund för vidare aritmetikkunskaper, medan andra forskare menar att det är viktigare att elever utvecklar räkneförmågor. Syftet med denna studie är att undersöka hur undervis-ning om tals del-helhetsrelationer i addition och subtraktion kan utformas ur ett variat-ionsteoretiskt perspektiv. Lärandeobjektet för undervisningssekvensen är att identifiera ett okänt tal i en del-helhetsrelation inom talom-rådet 0-10. Undersökningen gjordes med 13 elever i för-skoleklass genom ett förtest, en undervis-ningssekvens om tre lektioner samt ett efter-test. Undervisningssekvensen och testerna vi-deoinspelades för att utgöra underlag för ana-lys. Lektionerna gjordes för att visa olika vari-ationsmönster som kontrast, separation, gene-ralisering och fusion för att eleverna skulle kunna urskilja kritiska aspekter. Exempelvis användes ”part-whole bars” och kommutati-vitet i undervisningen för att synliggöra de kri-tiska aspekterna. De kritiska aspekterna som kom fram i resultatet var att urskilja att de två delarna ryms i och tillsammans är lika mycket som helheten, kunna ta hjälp av två tal i en relation mellan helhet och delar för att finna det tredje talet, kunna ta hjälp av helheten och en del för att hitta den andra delen och att kunna ta hjälp av kunskaper om tidi-gare del-helhetsrelationer för att hitta okända tal i nya del-helhetsrelationer.

Abstract [en]

The following thesis is an intervention study based on arithmetic teaching and part-whole relationships of numbers. Some researchers argue that part-whole relationships are a basis for further arithmetic skills, while other re-searchers believe that it is more important that students develop counting abilities. The pur-pose of this study is to investigate how teach-ing of part-whole relationships in addition and subtraction can be designed from a variation theory perspective. The object of learning for the teaching sequence is to identify an un-known number of a part-whole relationship, in the number range 0-10. The study was conducted with 13 students in preschool class through a pre-test, a teaching sequence of three lessons and a post-test. The teaching sequence and the tests were vide-otaped to provide a basis for analysis. The les-sons were designed to show different patterns of variation such as contrast, separation, gen-eralization and fusion so that the students would be able to discern critical aspects. For example, "Part-whole bars" and commuta-tivity were used in the lessons, in order to highlight the critical aspects. The critical as-pects that emerged in the result were to discern that the two parts fit in and together is as much as the whole, be able to use two numbers in a relation between the whole and the parts to find the third number, be able to use the whole and one part to find the second part and to be able to use knowledge about previous part-whole relationships to find the unknown number in new part-whole relationships.
