The first step is to identify what areas of education/instruction need to be improved. Student surveys are often the best place to get this information. Then, you should research availalbe technology from reputable sites like EDUCAUSE and the USDE's Office of Educational Technology. I think the most difficult part of implementation, once the needed technology is chosen/determined, is developing a plan that determines all stakeholders and clearly indicates the benefits to all stakeholders, especially the students. Providing the right amount and type of training on how to use the technology to both staff and students, is vital for buy-in and successful implementation and use of the technology.
