Abstract [sv]

Studiens syfte var att undersöka om elever utvecklar en förståelse för andragradsfunktioner genom att använda IKT-verktyget GeoGebra. Undersökningen gjordes i form av en fallstudie av sex stycken gymnasieelever som läste kurs 2c. Eleverna arbetade två och två med en uppgift som gick ut på att se vad som händer med grafen när man byter värde och tecken på variablerna i uttrycket y = - a(x + b)2- c. Elevmaterielet analyserades med en kombination av Ainsworths (2006) teoretiska ramverk, som har fokus på den matematiska processens förmåga att stödja lärandet, och Duvals (2006) ramverk om transformationer och representationer inom och mellan register. Studien kom fram till att det finns både nack- och fördelar att använda GeoGebra. Nackdelar, för att programmet inbjuder till att pröva sig fram, medan fördelarna är att eleverna analyserar och reflekterar under aktivitetens gång i GeoGebra. Eleverna gjorde både konventeringar och behandlingar med hjälp av GeoGebra.

Abstract [en]

The purpose of this study was to examine whether students develop an understanding of quadratic functions using ICT tool GeoGebra. The study was conducted as a singular case study of six high school students who studying course 2c. The students worked in pairs on a task to see what happens to the graph when changing value and sign of the variables in the expression y = - a (x + b)2 – c. Method used in the analysis of material was a combination of Ainsworths (2006) theoretical framework viewing function of the mathematical process ability to support learning and Duval (2006 ) framework of transformations and representations within and between registers. The study concluded that there are both advantages and disadvantages of using GeoGebra. The disadvantage is that the program invites you to trial and error, while the benefits are that students analyse and reflect during the activity in GeoGebra. The students did both conventions and treatments with help from GeoGebra.
