To the extent that she remains an anomaly, her methods will not have an impact. Regardless of the cultural myths inherent to law professors about the difficulty and challenge of their profession, the methods used by Cathaleen A. Roach require substantial work to implement and use. To the extent possible, her methods ought to be used to teach first year students in law school. Once the skills she advocates have been learned, the students will be able to carry those skills over to other classes. Using her methods, it is probably appropriate to have no more than 75 students in any first year class and preferably 25.
Several matters come to mind.
To the extent that real teaching is expected, and real learning required, that approach is justified. While few schools have student bodies whose attitudes would allow making co-curricular writing a requirement for graduation, the more, the better. Roach's method focuses on learning oriented writing. Co-curricular programs focus on demanding scholarly writing. Because of the substantive and substantial nature of these improvements, it is possible for these methods to become a substantial trend.
