Currently I am seeing "social reaction education" covering two forms. One is emergency/problem situation recognition and handling. The other is daily social interaction, and when and how to recognize and react to situations that are either possibily unpleasant for someone, or have potential future negative ramifications.
The basic concept here is instead of letting things develop until someone needs "anger management training", is to "train" people to : avoid things to get angry about or how to deal with them when unavoidable; not making others angry; recognize and defuse explosive situations (advanced).
But without focusing on one area or just a few. It's more about focusing on being a well rounded person that is functioning as a part of whole of society.
Currently I'm thinking that begining at young ages children are taught basic social norms in that culture. It's important to me that at this point it is very clear and insistent that children who's parents deviate from cultural norms are to be followed at home and in general with family. Understanding and applying social norms that deviate can be done when appropriate but always within parental wishes.
A bit combined in the early stages training/education, is more about covering all basic social skills. Mostly very basic, but at this point it can also be used as a rough guide for determining which individuals need more help, meaning referals to specialists to evaluate and recommend adjusting training or other steps.
Basic social skills training really should be aimed closer to young teenage groups, and can progress to more moderate level, and for those wishing, can move to more advanced training. Later basic social skills training should start to move into areas such as anger management and other negative aspects of life, and with a path to build up towards advanced levels aimed at professional careers.
The in school training can go up to things like when and how to intervene in situations between others that are possibly escallating into something dangerous, A first-aid crisis intervention. (Hopefully preventing the need for real first-aid.) Again, this should all be developed by professionals.
Two areas here that I can think of - how to recognize and respond in an emergency situation, and how to best assist professionals responding to an emergency.
Both of these areas should be curriculum developed by professionals in emergency response, with assistance from others, such as psychologists possibly helping with the first area.
Both of these areas need to cover scales from the one individual is the only non-victim or available to help person, through small groups, to large groups. And especially how to communicate effectively and work with each other.
