Two counter-points...
1. Computers in classrooms have rarely, if ever, been deployed to entire classrooms in the way that tablets can be. Typically, you&#x27;ll see one or two PCs in a class, plus a computer lab.  PCs don&#x27;t distract in the same way iPads can.<p>2. Calculators do make people worse at math.  I saw this first-hand with my son. As he went through school, they used calculators for everything. Students began to rely on the calculators for simple arithmetic and took the answers provided as gospel, not realizing that garbage in = garbage out.  He, along with many of his peers, never really developed the fluency in math to say to themselves &quot;hmm, that answer looks suspect. Let me try again.&quot;
