Digital isn't everything. The hardware gives advantages such as access to information, analysis tools, the ability to present and share information ... each of these opportunities would be nothing without the guidance and coaching of a live teacher with a pedagogically sound doctrine that seeks to grow self-directed and life-long learners.
As a leader in education you may have one shot at using your budget to demonstrate value in potential future investment in technology. Your best bet is to focus on:
1. low cost hardware with high speed, large bandwidth connection to the internet, such as tablets, Chromebooks, network printers and a small number of more capable machines for quality media editing
2. collaborative activities where investigations are planned together, roles are clearly defined, presentations are planned in advance and assessment involves an evaluation of not only the content produced but also the process used by students
3. search skills using multiple sources on multiple devices with a high level of evaluation of bias - know the truth from fiction - using sites like wikipedia where student work is open to critique on a global scale
4. use the cloud - for storage, sharing, processing large files, networking and to spend as little as possible on massive facilities.
In summary, make learning as rich as possible where the technology is supporting specific outcomes; leverage speed to give fun, effective practise at high-level skills.
