Do you know someone who is from a different culture than you? Perhaps they were born in a different country, speak a different language, or celebrate different holidays than you. Ask them to tell you about their cultural values and traditions.
We all have different stories and backgrounds; there is so much we can learn from each other if we simply ask, and take the time to listen! What better way to show someone that you care for and respect them than to ask them to share their story and culture with you?
So often it is a fear of the unknown that leads to misunderstandings and mis-communication. If we would all strive to know and understand people that are different from ourselves this world would be a much more peaceful place.
Get out of your comfort zone and meet someone who is different than you. Befriend them and get to know them. If you really want to learn about another culture, travel to a foreign country and experience it for yourself! Or volunteer to be a host family for a foreign exchange student, introduce them to your own traditions and culture and ask them about theirs. Do volunteer work with refugees and do your best to listen and help them share their stories and culture with you.
If you live in a major city you don't have to go far to encounter people from another culture. Be intentional about striking up a conversation with someone on the bus next to you, or in the elevator. Even if you are in a smaller town or suburb you can find others who are different from you--simply be intentional about saying hello at first, and then the next time you see them try for a little more conversation. Once trust builds you will both be more likely to share and learn from each other. If you are a very shy person, you can still learn about other cultures through books or television programs. The more you know about the larger world around you, the better you will be able to relate to the people around you.
If you are a teacher or instructor, you may be interested in World Wide Learn; a site that offers resources on how learning is approached in various cultures around the world.
If you really enjoy learning about other cultures, you could consider subscribing to something like the Cultural Anthropology Journal.
