Culture determines what kind of thinking is important and what kind is not so important. L

earners use the language, tools, and practice their culture to learn concepts. Although students have their individual learning styles, their learning styles are often combined with cultural values. For example, Navajo (North American Indians living in Arizona, New Mexico, and Utah) children often learn first by observing and listening. Then, when ready, they continue learning on their own in cooperation with and under the supervision of an adult. In this way, the children learn all the skills they need. Navajo children speak very little during this process. In contrast, many African American children learn effectively by acting and performing. They like classroom activities such as oral presentations, role-plays, and dramatic performances. Lots of talking is useful for these students. Another way of learning is through reading and writing. Asian students generally need writing to support their learning, and therefore do well in classes where there is lots of reading and writing. It is common to see Japanese students pay special attention to the spelling of words they have learned. They are more comfortable seeing new materials than hearing them. Koreans are believed to be the most visual (can be seen) learners. So, although learning styles greatly determine how a person takes in new materials, one's culture also influences how he learns.
