As the number of computers accessible to students and teachers has increased, there has been a growing emphasis on integrating technology across the curriculum. Even though schools increasingly invest in new technologies, the actual use of computers in classrooms remains limited. This paper examines a model developed to guide the implementation of a Preparing Tomorrow's Teachers to use Technology (PT[3]) project and its capacity to promote improvement of teachers' ability to integrate technologies into their instructional practice. The essential conditions, identified by ISTE, provided the foundation on which this model was developed. Emphasis was placed on access, professional development, support, incentives, and assessment, with the remaining conditions embedded within. The findings indicate that the model was effective in improving teachers' technical skills and their ability to integrate technology into instructional practice.
