Be sure to start by writing a vision and mission for integration. Ask stakeholders to take part in this process so that you have a good idea of what the front line teachers know about the students.
Then assess your infrastructure and see what is possible. Going one-to-one anything without reliable connections is a frustrating waste of money, time, and man power.
Once you have these in place the decisions on technology should answer itself. Keep in mind that you will need to build in on going and appropriate professional development to support the plan. Appropriate PD should teach them how to integrate into their own discipline. Tech use is never one-size fits all.
