Maslow's hierarchy of needs is perhaps most relevant today in terms of the education of young people. Many countries are worried that they are not doing a good enough job of educating their youth, particularly those from less-advantaged backgrounds. Maslow's hierarchy tells us that, in order to educate these children well, we must first attend to their physiological needs (are they getting enough to eat) their safety needs (are their schools and homes safe) and possibly even their love and belonging needs (do they have home environments that fulfill these needs). In this way, Maslow's ideas help us to have a better understanding of what is needed in order to educate children.
There are other applications of Maslow's hierarchy. For example, advertisers try to connect their products to various of the needs to make use want to buy them. However, I would argue that the educational applications of Maslow's theories are the most relevant.
