    Tre gånger så många eller Tre gånger fler: En kvantitativ studie kring hur elever tolkar vanliga aritmetiska jämförelser2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Mathematics should, as far as possible, be expressed unambiguously – there should be no doubt what is meant with a mathematical expression. There is no reason why arithmetic comparisons should be treated differently. However, there are suggestions that arithmetic comparisons could mean different things, depending on how they are presented.The aim of this study is to investigate how students in the grades 4-6 (age 10-13) interpret arithmetic comparisons in mathematical text assignments. Arithmetic comparisons refer to as proportional relations which describe a relationship, for example between two quantities. Do students separate comparisons as three times as many and three times more? 

    How do students interpret the comparisons double and half? 

    Do the interpretations differ between boys and girls? 

    Do the interpretations differ between students with Swedish as first language and students with Swedish as second language?

    The study is based on a survey in which 188 students participated. The analysis shows that the absolute majority of students in the study interpret times as many and times more as synonyms. Most students also make the generally accepted interpretation of the comparisons double and half.

    Structure sense: Ett matematikdidaktiskt begrepp som håller på att formas2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Structure sense är ett begrepp som nyligen har börjat användas inom matematikdidaktik föratt beskriva elevers förståelse för matematiska strukturer. Syftet med det härexamensarbetet är att utforska begreppet structure sense genom att jämföra olikadefinitioner av begreppet. Vidare är syftet också att jämföra structure sense med tre andraliknande begrepp: symbol sense, personal structure och awareness of mathematical pattern and structure. Litteraturstudien bygger på 13 vetenskapliga publikationer som samlades in ochanalyserades. Samtliga publikationer är skrivna av internationella forskare. I resultatetpresenteras och jämförs structure sense utifrån fyra olika definitioner. De olikadefinitionerna av begreppet är riktade mot olika nivåer av matematik men gemensamt förbeskrivningarna är att structure sense uppfattas som en eller flera förmågor som innefattarett mångfacetterat sätt att uppfatta matematisk struktur.
