Try:
Module[{b = a}, (Print[b]; Manipulate[b=a;b^2, {{a, 1}, 0, 5}])]
The issue is that Module[{b=a},...] only assigns b initially. You need to
update its value later.

I expected the following expression to show the square of the current value
of the slider, but it shows only a^2. There is clearly something I don't
understand about Module. Any insights?
Module[{b = a}, (Print[b]; Manipulate[b^2, {{a, 1}, 0, 5}])]
