The PLSA (Probability of Large Scale Adoption) Predictors

Education Technology Solutions (Australia), Vol 22. (May 2008)

Our technology department here in the Mankato Area Public Schools (Minnesota, USA) likes what we call “wins” – projects that actually result in a large number of staff members using and benefiting from a technology-based resource we’ve helped put in place.

Like all technology departments, we have finite resources, both human and capital. We’ve invested in projects that really take off – and unfortunately a few other projects that have crashed with a resounding, and sometimes expensive, thud! Those “thuds” most memorable include:

While none of these projects was either financially or educationally catastrophic (I AM still employed), each cost the district and our department many hours of professional and technician time and decreased our credibility.



The rubric below can be used to help objectively determine the Probability of Large Scale Adoption (PLSA) in a school.

Schools and libraries with different resources and priorities will obtain different ratings. Remember - small schools around our district use interactive television extensively, but we do not, because of our districts’ relative sizes.

Getting a “zero” in either the Usefulness or Affordability categories would seem to negate high scores in the others. Should these be more heavily weighted? And usefulness in itself seems to be a trump card – if the need is great enough, other factors are less important.

This is how I would rank some technology applications in our district, where we are adequately, but not over, funded.

In my estimation, the total point score correlates with the percentage of teachers actually doing these sorts of things in our district.

Right now, what are the chances of large scale adoption in your district of these technologies?

Use the chart next time someone suggests a new technology project. Even if you don’t use the numbers, the rubric can provide fodder for good discussion.

As leaders and administrators we need to do a better job of predicting what new technology resources and efforts will make it and which will not. A dollar spent on a failure is one less dollar spent on something beneficial to our students. New initiatives need to based on more than good sales pitch.
