Whether they know it or not, students who are studying a second language today find themselves in a fortunate position. While high school and university students are exposed to a number of fields such as biology, anthropology, and music, little is known about how students best learn about ecosystems, ancient cultures, and melody. However, much is known about how people acquire a second language. Indeed, scholars have been studying in earnest the manner in which people acquire a second-language for more than twenty-five years. While there is much that we do not know about second-language acquisition, researchers have been able to identify the most important cognitive, classroom, and social conditions that facilitate the learning process.
