In this paper,the background,theoretical framework and design of the Swedish part of an international comparative study of Technology Enhanced Teacher Professional Development(TETPD)are presented.The focus of the paper is on Teacher Professional Development(TPD)in areas of ICT and education in which ICT is considered as a technology that could enhance the practice of teaching and learning.The further aim of the paper is to provide a framework for a multiple case study in Sweden in two dimensions.The first dimension concerns ownership and management including both top-down governmental programs and bottom-up participant driven initiatives.The Second dimension concerns methods or modes in which both traditional face-to-face programs and programs run in virtual environments as online communities are included.Through the use of the framework,four different cases that are described as programs in which ICT is used in and for TPD are selected.The four cases are presented and related to the different perspectives on models and programs for TPD,and the new perspective on TPD suggested by Villegas-Reimers. The significance and prospect of the programs in terms of enhancing the use of ICT for teaching and learning are then discussed.
