Aspects of knowledge for teaching mathematics to students with Down syndrome: insights from a community of teachers.

This research, presented in the article, aimed to investigate aspects of knowledge necessary for teaching Mathematics to students with Down syndrome elicited within the formative context of a community of teachers. Adopting a qualitative, intervention-research approach, a group of seven teachers specializing in Mathematics education for students with Down syndrome was formed. These educators worked in both special education schools and mainstream schools. The group interacted synchronously and asynchronously, as the training occurred before and after the onset of the COVID-19 pandemic. Data were collected using audio recordings, field diary notes by the researcher, and records of interactions in a WhatsApp group. Analysis of the produced information was guided by three emerging aspects from the data set: a) Down syndrome, potentials, and challenges related to Mathematics; b) knowledge of the concept (number) for teaching and learning in students with Down syndrome; and c) curriculum adaptation and the use of multisensory materials. In conclusion, formative actions based on a community of teachers allow for a flexible work plan, leading the teacher to consider the specific difficulties, skills, and motivations of students with Down syndrome in Mathematics education. This approach values the diverse perspectives of teachers and the importance of sharing their knowledge and experiences, addressing the emerging needs of the group, and articulating their interests and practices.
