There is a large body of literature for law school professors on the subject of pedagogy. One bibliography of such literature, which excluded pieces that discussed general curricular issues, located 209 articles for the period of 1993-1999. Some of these articles attempt to persuade professors to employ different teaching methodologies, while others encourage the discussion of a wide variety of issues previously excluded or marginalized in traditional law school core courses. Some suggest that traditional first-year law school courses should include the perspectives of clinicians. Others advocate for the discussion of diversity and multicultural concerns across the law school curriculum. For example, some critical legal scholars argue that issues concerning women and minority groups must be included because of the belief that traditional courses overrepresent the perspective of white heterosexual males. While other critics of legal education argue that law school should include more discussion of other disciplines such as economics, literature, or sociology, other scholars yearn for more discussion of morality and values in the law school curriculum and advocate for more discussion of international legal issues within traditional first-year law courses.
