Influencia del pensamiento visual y el uso de representaciones múltiples en el desarrollo de la resolución de problemas matemáticos en estudiantes de Educación General Básica.

Mathematical problem solving in Basic General Education remains a pedagogical challenge closely related to conceptual understanding, representation, and logical reasoning. This study aimed to analyze the influence of visual thinking and the use of multiple representations on the development of mathematical problem-solving skills at this educational level. A quantitative approach with a quasi-experimental pretest–posttest design was applied to a sample of 120 fifth-, sixth-, and seventh-grade students from public urban schools. The intervention was based on the systematic use of diagrams, schemas, and visual representations within active learning methodologies. The results revealed statistically significant improvements in problem interpretation, procedure selection, and solution justification, as well as an increase in high-performance levels. The study concludes that visual thinking and multiple representations are effective instructional strategies for fostering meaningful and functional mathematical learning in Basic General Education.
