Una nueva forma de enseñar suma y resta con el algoritmo abierto basado en números y su impacto en el tercero de básica de la Unidad Educativa "Luis Cordero"

Abstract

This innovation study arises from the need to contribute and improve the results obtained by Ecuadorian students in both national and international academic tests, in which, they did not reach the basic levels in Mathematics. This is supported through a study conducted by Ablewhite, in whose research the author considers the traditional form of teaching to be ineffective for meaningful learning. For this reason, it is intended to implement the Open Algorithm Based on Numbers (ABN), created by Professor Jaime Martínez Montero to the Teaching of arithmetic operations addition and subtraction, in the subject of Mathematics in the third-year students of Basic General Education of the Educational Unit "Luis Cordero". The methodology of the project is framed by the socio-critical paradigm and the mixed methodological approach (quantitative-qualitative), using the Dominant Model Concurrent Nested or Embedded Design (DIAC) and an exploratory scope, in which 44 participated students of the aforementioned degree, 22 of the parallel "A" and 22 of the Parallel "B", together with 2 teachers. The implementation of the proposal contributed to the improvement of learning conditions regarding academic performance and the student's attitude towards Mathematics. The conclusions obtained determined that prior to the implementation of the ABN Algorithm in addition and subtraction, students had difficulties in working on these same topics with the Figure-Based Closures Algorithm (CBC), as they do not dominate previous themes, for example, successions and Regressions. In response to this problem, the ABN Algorithm is a great contribution to the teaching process learning addition and subtraction, including counting, this is determined from the comparison of results obtained in the summative assessment among students of the parallel "A", who used the CBC algorithm and the students of the third of basic, parallel "B", where the ABN algorithm was implemented, where it is clear that the methodology implemented, in the students of the second group, allows the overcoming of difficulties of improving their academic performance and manifesting a positive attitude towards mathematics.
