Reflections on the Documentational Work of Two Teachers in a Remote Collaborative Environment for Compound Interest Teaching

Celina A.A.P. Abar, Chrystian Bastos de Almeida


Background:  Documentational Approach to Didactics was adopted, this way considers a continuous process in which resources, associated with the utilisation schemes, are transformed into documents.  Objectives: Characterize the Documentational Genesis of two High School Mathematics teachers in remote collaborative work for teaching Compound Interest articulated with the GeoGebra software. Design: As a methodological framework, the reflective investigation methodology was used, in which the teachers contribute to data collection and analysis. The paper was structured in four professional situations: reflection situation, training situation, implementation situation, and confrontational situation. Settings and participants: Teachers worked from March to June 2021, and resources were developed through the Google Docs and Google Meet virtual platforms and later made available on Classroom. Data Collection and Analysis: Data obtained through the recordings of the meetings and the proposals of the participants, analysed according to documentational trajectory concept, the instrumentation and instrumentalisation dialectics, productive and constructive activity dialectics, and the self-efficacy concept. Results: Based on our analyses, it was possible to characterise the teachers’ Documentational Genesis. Conclusions: The Documentational Approach to Didactics was relevant to the study because it was possibly identified the resources in individual and collective utilisation schemes, mobilised in the documentational work and in class implementation by the teachers and the instrumentation and instrumentalisation dimensions in document construction for teaching Compound Interest, i.e., the Documentational Genesis process. In addition, we have identified the teachers’ self-efficacy during the documentational work and implementation of classes on Compound Interest.
