A comprehensive approach for integrating technology into a TESOL teacher preparation program is described. Ten specific ways to assure constructivist technology use in teacher education are highlighted. These techniques have been synthesized into a compact model with three pillars: (a) electronic assessment system (e-portfolios for individual assessment and program evaluation), (b) teacher candidates' technology-based course assignments and performances, and (c) Web-based instruction and communication. The authors claim that within this three-pronged model flexibility of implementation is key to success for preservice and in-service teachers.
