Many people find Chinese a hard language to learn. Using the Theory of Variation as the primary learning framework, the authors of this book conducted a number of large-scale and robustly-designed studies to investigate the relationship between the learning and teaching of Chinese. The authors believe that there are effective ways to become skilled in Chinese and that learning Chinese can be pleasurable and interesting. They provide empirical evidence for educators, parents, policymakers and readers interested in Chinese language education. They also illuminate the path to the mastery of Chinese in schools and how Chinese should be taught in today’s world.
