If you want to learn Smalltalk, there is a MOOC that’s just started. http://files.pharo.org/mooc/. Also Pharo by example is a good book.
Also, in the actual MOOC, for which you have to register at https://www.fun-mooc.fr/, the videos are also available dubbed in English. (Except some that are not part of the "actual" course that give tips on how to use the environment.)
