While correct it requires that you ignore what happens during the
turnaround. In other words the solution is not complete. To
complete the solution requires GR.
The fact that SR will not change
the results significantly does not alter the incompleteness of the
SR solution.
It seems simple to say that one must change
timekeeping to the new frame, but I suspect from the point of view
of the beginning student this is a large leap. Indeed just
understanding a spacetime diagram would be a large leap for such a
student. As a result they might still tend to see it as
paradoxical. One can certainly speculate as to what the moving twin
observes during the acceleration, but this is not properly predicted
by SR.
