Resumen
El estudio se centra en los problemas de los estudiantes de grado octavo de la institución Pablo Sexto ante la suma de expresiones algebraicas. Lo anterior, al comprobar dificultades al reconocer variables, conceptos análogos y el manejo de recursos algebraicos. La metodología es cualitativa, basada en la sistematización y el paradigma interpretativo, articulando diagnóstico, diseño y utilización de una secuencia didáctica más la evaluación de los aprendizajes. Se revisó el espacio físico, se usó la gamificación, la modelización matemática y actividades grupales, incentivando el paso de lo concreto a lo abstracto. En los resultados, los progresos en comprensión conceptual, aplicación procedural y desarrollo actitudinal, fueron considerables; aumentó la participación y el compromiso, el trabajo en equipo y el entusiasmo, aunque conceptos como grado absoluto, grado relativo y parte literal, siguieron siendo problemáticos. Por su parte, la discusión ratifica que la mezcla de vivencias, reflexión metacognitiva y enseñanza estructurada, enriquece el conocimiento. Así, la enseñanza gamificada en contexto beneficia el aprendizaje algebraico y el pensamiento crítico, por lo cual, se recomienda la formación docente, los estudios longitudinales y la adaptación de la perspectiva en distintos ámbitos escolares para garantizar la estabilidad de los aprendizajes y su aplicación en la práctica cotidiana.
The study focuses on the challenges faced by eighth-grade students at the Pablo Sexto Educational Institution in understanding the addition of algebraic expressions. This is based on the identification of several difficulties in recognizing variables, analogous concepts, and managing algebraic resources, according to an initial diagnostic assessment. The methodology is qualitative, grounded in systematization and the interpretative paradigm, integrating diagnosis, design, and implementation of a didactic sequence along with the evaluation of learning outcomes. The approach involved reviewing the physical space, employing gamification, mathematical modeling, and group activities, encouraging the transition from concrete to abstract thinking. The results showed significant progress in conceptual understanding, procedural application, and attitudinal development; there was an increase in participation, engagement with the subject, teamwork, and enthusiasm, although challenging concepts such as “absolute degree,” “relative degree,” and “literal part” remained prominent. The discussion confirms that combining experiential learning, metacognitive reflection, and structured instruction enriches knowledge. Thus, gamified, context-based teaching supports algebraic learning and critical thinking, and it is recommended to provide teacher training, conduct longitudinal studies, and adapt this approach across various educational settings to ensure the retention of learning and its practical application.
