Resumo: | The present article aims to report the results obtained in a Master's research on the mobilized knowledge concerning the positional value in the Decimal Numbering System (DNS) by nine-year-old students. We bring as theoretical assumptions the research contributions by Lerner and Sadovsky; Zunino; and Brandt, who discuss the construction of the positional value in the DNS by students in the initial years of Elementary School. Based on a qualitative methodology, we applied an instrument comprising six activities. Participants mobilized knowledge concerning numerical sequences, Lerner and Sadovsky comparison criteria, the positional value, and the influence of spoken numeration on the written number record. According to the analyses, we can infer that the construction of knowledge regarding the positional value in the DNS is a long and progressive process, which is not only a matter of memorizing the numerical sequence. |

The positional value in the decimal numbering system: a study with students from the earliest years of elementary school O valor posicional no sistema de numeração decimal: um estudo com alunos dos anos iniciais do ensino fundamentalThe present article aims to report the results obtained in a Master's research on the mobilized knowledge concerning the positional value in the Decimal Numbering System (DNS) by nine-year-old students.

Como pressupostos teóricos, utilizamos as contribuições das pesquisas de Lerner e Sadovsky; Zunino e Brandt, que abordam a construção do valor posicional no SND por alunos dos anos iniciais do Ensino Fundamental. Baseados em uma metodologia qualitativa, aplicamos um instrumento composto por seis atividades. Os participantes mobilizaram conhecimentos relacionados à sequência numérica, aos critérios de comparação de Lerner e Sadovsky, ao valor posicional e à influência da numeração falada no registro escrito dos números. De acordo com as análises realizadas, podemos inferir que a construção do conhecimento sobre o valor posicional no SND é um processo longo e progressivo, não se resumindo a memorizar a sequência numérica.Universidade Federal de Santa Catarina2021-11-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/alexandria/article/view/7557110.5007/1982-5153.2021.e75571Alexandria: Revista de Educação em Ciência e Tecnologia; v. 14 n. 2 (2021); 181-2081982-5153reponame:Alexandria (Florianópolis)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/alexandria/article/view/75571/47468Copyright (c) 2021 Alexandria: Revista de Educação em Ciência e Tecnologiahttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessTracanella, Aline Tafarelo Bianchini, Barbara Lutaif 2021-11-16T15:23:05Zoai:periodicos.ufsc.br:article/75571Revistahttps://periodicos.ufsc.br/index.php/alexandria/oai1982-51531982-5153opendoar:2021-11-16T15:23:05Alexandria (Florianópolis) - Universidade Federal de Santa Catarina (UFSC)false |
