I asked Andy Blunden for his explanation of Vygotsky's concept of the social situation of development, and here it is! Thanks, Andy. (Originally published Feb 10, 2020)
Highlights include:
0:07 - How do we get from dependent newborn to independent adult?
1:16 - development takes place through a series of 'unique' stages
2:38 - resolved 'predicaments' fuel the transition between stages
4:54 - to get new needs met, the child overthrows the former situation to establish a new role
5:54 - mutual reinforcement between development and the social situation of development
8:05 - the social situation of development, concisely defined
8:38 - a preview of perezhivanie and adult development
