A mediação pedagógica com o material multibase dienes e fichas numéricas: um estudo de caso sobre a aprendizagem da adição por estudante com transtorno misto das habilidades escolares

Abstract

The objective of this work is to analyze the impact of pedagogical mediation using the Dienes Multibase Material (MMD) and number cards on the learning of addition by a student with Mixed Disorder of Scholastic Skills (MDSS). Inserted in the context of Inclusive Mathematics Education, this study recognizes the challenges faced by students with learning difficulties and the importance of differentiated teaching strategies. The research was configured as a qualitative case study, carried out in a rural school, in the locality called Papagaio, district of the city of Pesqueira/PE, with the student João (a fictitious name adopted by the authors). The intervention took place in the school library, which also serves as the Specialized Educational Service (SES) room, involving 1 (one) student. The results indicate that the structured pedagogical mediation and the integration of the number cards into the Dienes Multibase Material facilitated the construction of the concept of number and the addition operations, promoting greater student engagement and autonomy. Thus, it is affirmed that individualized pedagogical mediation and the use of manipulative materials prove to be effective tools for promoting mathematical learning in inclusive contexts.
