About TDSIG
Who we are
IATEFL Teacher Development Special Interest Group provides a forum for us to develop our potential as teachers, to cultivate our abilities to navigate the challenges and successes of being a teacher, and to invigorate us in our ongoing work.
Anyone interested in such developmental issues can share their experiences and learn from the experiences of others. Through such a network, our community seeks to encourage individuals and groups of teachers to undertake activities that focus on personal and professional development.
TDSIG was formed by Adrian Underhill in 1985, and was one of the first distinct IATEFL SIGs.
Our aims:
- To enable and encourage all categories of teacher to take more responsibility for professional and personal evolution throughout their careers.
- To promote individual and institutional awareness of the importance of teacher development.
- To encourage the provision of facilities for teacher development which do not already exist.
