Sustainability of professional development programmes to teach mathematics using technology
Résumé
The literature recommends using technology for a more effective approach to teach mathematics. To integrate technology into pedagogical practices, it is necessary to implement sustainable professional development programmes for in-service teachers. This paper researches the impact and sustainability of these programmes with in-service mathematic teachers, aiming to find out how they influence pedagogical practices, using a mixed research methodology, with qualitative and quantitative data. The results show that, at the end of the programmes, teachers reveal high levels of satisfaction with their effectiveness. However, although technology is used by most teachers, who appropriate it as a teaching tool, many teachers do not propose tasks for students to use technology in learning, which compromises the sustainability of the programmes. It was also found that the teachers’ years of service is not critical for the sustainability of the programmes.
