Subtitling a forum on innovation to include the phrase "disruptive technology" misunderstands the purpose and potential of educational technology. Technology is not disruptive; the way in which technology is used can be disruptive.
You can substitute any tool in that sentence. Standardized tests are not disruptive; the way in which they are used is. An air horn isn't disruptive if you use it properly.
The forefront issue in emergent technology is implementation, specifically providing the scaffolding and professional development to design and redesign instruction in order to meaningfully integrate the technology into learning experiences and the acquisition and mastery of skills.
We continue to supply tools without supplying the skills not only to use them, but to meaningfully design robust integrative curricula and employ robust integrative pedagogy to facilitate student skill mastery and achievement.
It is backward-looking and misaligned to refer to technology in schools as "disruptive" as a matter of fact.
