Below is a list of studies comparing comprehension-based methods with traditional methods that demand the conscious learning of grammar. The list includes studies contrasting comprehension-based methods with traditional methods for beginning foreign language teaching and intermediate foreign and second language teaching, as well as studies showing the superiority of self-selected reading over traditional instruction for intermediate second and foreign language students.
All studies included comparison groups and subjects were high school age or older. In addition, there are a multitude of studies that confirm these results using multivariate techniques and case histories (Krashen, 2004).
