Any journal or conference papers relating to the effectiveness of software used in classrooms for speech, language and communication and also for educational use.
I encourage you to consider the following new publication: Innovative Technologies to Benefit Children on the Autism Spectrum by Nava Silton: http://www.igi-global.com/book/innovative-technologies-benefit-children-autism/94532. I wrote a chapter on our federally funded research on iPrompts, an educational software that helps students with transitions.
