Loops in programming : An intervention study on how tasks can be designed to create an understanding of loops (English)
Abstract [sv]

Programmering är ett område i matematiken som relativt nyligen blev en obligatorisk del i de svenska styrdokumenten. Flertalet studier poängterar behovet utav ytterligare , i detta förhållandevis nya ämnesinnehåll, som kan bidra med didaktiska och pedagogiska perspektiv på hur en undervisning i programmering kan utformas. Loopar är ett utav de grundläggande begrepp inom programmering som elever upplever svårigheter med. I ett försök att bidra till det som forskning efterfrågar syftar denna studie till att undersöka hur skapandet av liksidiga geometriska figurer i visuella programmeringsmiljöer, med inspiration av realistisk matematikundervisning, kan utveckla elevers förståelse för loopar.

För att uppnå syftet att undersöka hur geometriska figurer och lärandeteorin realistisk matematikundervisning kunde inspirerar till en undervisning som gav möjlighet till lärande kring loopar genomfördes en interventionsstudie, en design research. Den cykliska process som följdes resulterade i en planerad lektionsdesign som applicerades på en elevgrupp i årskurs fyra. Lektionsdesignen reviderades och applicerades på nytt i en ny elevgrupp. Materialanalysen ledde till ett resultat där två stycken designprinciper identifierades, guidande frågor och regelbundenhet. Principerna bidrog till att skapa förutsättning till ett lärande angående loopar och skulle kunna användas som inspiration till undervisning. Guidande frågor, som tog inspiration av guided reinvention i realistisk matematikundervisning, ledde till en helklassdiskussion där loopens funktion fick återuppfinnas hos flertalet elever. Principen Regelbundenheten var det bidrag som liksidiga geometriska figurer kunde ge till förståelsen av loopar som används för att upprepa något ett visst antal gånger.  

Abstract [en]

Programming is an area of ​​mathematics that has recently become a mandatory part of the Swedish curriculum. Several studies emphasize the need for research, in this relatively new mathematical content, which can contribute with didactic and educational perspectives on how teaching and tasks in programming can be designed. Loops are one of the basic concepts in programming that students show difficulties with. In an effort to contribute to what research is inquire for, this study aims to investigate how the creation of equilateral geometric figures in visual block-based environments, inspired by RME, can develop students' understanding of loops.

 

To achieve the purpose of investigating how geometric figures and the learning theory realistic mathematics education could influence students' learning about loops, an intervention study was conducted using the design research method. The cyclic process that followed resulted in a lesson design that was applied to a group of students in grade four and then revised to be further examined on a new group of students. The material analysis led to a result where two pieces of design principles could be extracted, guiding questions and regularity. The principles helped to develop students' learning about loops and could be used as inspiration for teaching. Guiding questions, which took inspiration from guided reinvention in RME, led to a full-class discussion where the loop's function could be reinvented in the majority of students. Regularity was the contribution that equilateral geometric figures could make to the understanding of loops that repeat something a certain number of times.
