The reason why ethics differs when we're talking about people, companies, nations is that all of these have interests which may differ. What happens then with differing interests is that it also lead to different moral and value systems which again in turn lead to different ethics. Most usually, the actual source why ethics differ is either due to the interests or wishes of a particular social group mentioned here.
I would positively imagine myself integrating Vygotsky's notion of scaffolding, such as mixed age grouping or heterogeneous reading or maths groups.
Explanation:
Vygotsky's notion of scaffolding is a part of educational concept of Zone of proximal development also called ZPD.
It says that the set of skills that a child or a student cannot achieve by himself, can be achieved with the help of someone else.
For example: In a mixed- age group reading, a kindergartner would not be able to read a story book of a length by himself, as he is just learning to read and write.
But with the help of kids who are older than him, the child would be able to learn the letters and some small sentences faster.
