Otra vertiente de esa historia es su influencia en el surgimiento de otras ciencias y aplicaciones, cuyos desdoblamientos durante la posguerra contribuyeron al aumento de la racionalización de la sociedad moderna. El objetivo de la investigación no es detallar sus técnicas, sino entender sus orígenes y desarrollo, cuyo éxito es atribuido a la práctica interdisciplinar. Los resultados de la investigación posibilitan la discusión de temas tales como la interdisciplinariedad; interacciones entre resolución de problemas prácticos e investigación; valorización de la matematización y globalización de procedimientos y métodos; modelado matemático y, por fin, cómo el conocimiento científico puede ser moldeado por los intereses políticos y sociales.","PeriodicalId":38914,"journal":{"name":"Bolema - Mathematics Education Bulletin","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1590/1980-4415v32n61a03","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67287402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, in this paper we aim to understand the potential of situations that suggest incorrect knowledge extensions as a means to promote the construction of decimal number understanding. Part of a broader study that follows a Design Based Research is reported, within which a teaching experiment was carried out with 25 students and their teacher, in 3 and 4 grades. In this paper, we analyze the discussions among four students, organized in pairs, regarding tasks that promoted the discussion of three common incorrect knowledge extensions. The results evidence that the proposed situations promote the use of justifications and counterexamples, developing mathematical reasoning. The results also reveal the potential to build decimal number understanding, namely in models use, unit conceptualization, and place value concept, in particular zero.","PeriodicalId":38914,"journal":{"name":"Bolema - Mathematics Education Bulletin","volume":"32 1","pages":"631-652"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41924718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
