Résumé
This paper presents a case study of a decade-long technology-enabled teacher professional development (TPD) initiative for government-run school teachers in India. The TPD aimed at capacitating teachers in integrating project-based or constructivist learning with technology in curriculum and pedagogy. Teachers are central to the teaching–learning processes, and hence capacitating them to leverage digital technologies confidently is essential to improve the quality of education imparted to learners. This paper focuses on the use of innovative technologies leading to the education of teachers. A decade of TPD is divided into three phases providing an analytical framework for the evolving technologies and pedagogies across the phases. Documents, resources and tools used for the TPD activities, researchers' first-hand experiences and documented research studies supported the comparative analysis of the three phases of TPD. This comparison highlighted leading-edge technologies influencing changes in TPD delivery mode, learning support, pedagogy, scale, etc., across the phases. The paper also maps the interrelationship between technologies and pedagogies of TPD, suggesting various features of innovations such as continuous, practice-based, collaborative, scalable, shareable, transferable, and adaptable.
