Usando algoritmos e ábaco no estudo do sistema de numeração decimal em um curso de Pedagogia Using algorithms and abacus in the study of decimal numbering system on a course of Pedagogy

Studies in Mathematics Education have described difficulties of teachers in the use of al gorithms in arithmetic teaching in the initial grades, difficulties leading to questions about the quality of theoretical and practical training provided for teachers in this area. In this context, the present study aimed to investigate the formation of concepts and construction of mathematical knowledge of Pedagogy students in relation to arithmetic teaching, basic operations using abacus and algorithms, as well as the decimal numbering system. In the theoretical approach, the authors reflect on initial teacher training for Mathematics tea chers in the initial grades, the necessity of training grounded in knowledge to the process of teaching/learning and the importance of teacher training in methodological contents
