Método Po-Shen Loh: uma nova perspectiva para resolução de equações quadráticas

Abstract

This research paper addresses the Babylonian method, which was rediscovered and called the Poh-Shen Lo method for solving quadratic equations. The objective of this paper is to show the practicality of the method rediscovered by Professor Poh-Shen Lo, in order to establish whether there are advantages in its didactic use. Standing out for being a simple and intuitive approach, the Babylonian method, which was generalized by Professor Po-Shen Loh, and proposed as a pedagogical approach. In general, the study of quadratic equations is based on an excessive amount of formulas, all content is covered without justifications. The aim was to highlight the importance of history in mathematics classes, recalling some civilizations and mathematicians who contributed to the discovery of formulas and practical solution methods. The methodology adopted in the research is predominantly qualitative, of the bibliographic review type. As a methodology, in addition to bibliographical research, this work was dedicated to the development of a case study in a second-year high school classroom in the metropolitan region of São Luís - Maranhão, so that lesson plans, practical mathematical tests and questionnaires were developed with the objective of measuring not only the difference in the teaching effectiveness of the analyzed methods, but also the level of satisfaction of the students when doing them. In addition to the collection of data from students/master's students of the active PROFMAT-UEMA classes. Finally, as a result, few results were verified in the class when taught through the Poh-Shen Lo method in relation to the Bhaskara method. A considerable low self-esteem of the students in relation to their mathematical knowledge and a generalized low performance were noticed. Thus, this approach is important considering the current situation of Mathematics teaching, which requires other pedagogical resources, in addition to new didactic guidelines that can be used in the classroom in order to make them more attractive and stimulating for the students
