Razonamiento geométrico y bidimensionalidad en estudiante de grado sexto con discapacidad intelectual

At the present study, it was proposed to investigate the development of geometric thinking and two-dimensionality in students with cognitive disabilities from the Van Hiele model. A case study was used with a 12-year-old participant with intellectual disabilities. The prognosis showed that the participant was at Van Hiele level 1, that is, he could identify basic geometric shapes and classify them according to their shape. However, he had difficulty understanding the properties of geometric shapes and performing basic geometric operations. Based on these results, a didactic sequence is proposed that uses specific materials, recreational activities and feedback to determinate the shortcomings, identify the improvement opportunities and straight their learning. Once the sequence was applied, it was evident in the exit test that the student advanced to level 2 of Van Hiele, where, through the test, the student demonstrated that he could identify properties and parts of the geometric figure and in turn associate them. The results of this study indicate that a student with cognitive disabilities can develop his geometric and two dimensional thinking with appropriate support. The proposed strategies can help teachers design learning activities and experiences that are meaningful and accessible to such students. It was also concluded that educational inclusion must be done through tangible actions in the classroom, in order to reach true inclusive education in the not too distant future.
