As a manager, I would start promoting that he solve his own issues first, and then ask for input on a given solution ( showing effort and initiative ).
There area slew of online resources to use to get them started towards a solution, and to validate his approach. I might even suggest that he assign a SR Developer as a mentor.
The other thing I would say is if he ever wants to move up past JR, they will have to develop the traits of initiative and effort to resolve your own problems ( tasks )
