Basically, for ruby and javascript we had (very informal) coaching sessions together roughly once a week (around 2 hours each). I would walk her through core syntax problems (how to use functions, objects, arrays) and give her some hints of what APIs to look for. And then she went and researched and tried a lot of stuff (sometimes more than 8 hours a day) and would ask me when she got totally stuck. I would then try to not give direct answers but hint at where to look for or how to develop some sort of divide-and-conquer strategies. And then I was kinda amazed at the results ;)
