The teaching of international organization (IO) poses unique challenges. One is deciding whether to take a broad global governance-IO approach dealing with the creation, revision, and enforcement of rules that mark different governance arrangements, the roles of formal, informal, intergovernmental, and nongovernmental IOs, and the politics, dynamics, and processes of problem-solving and governance in various issue areas, a theory-driven approach, or an IOs approach focusing primarily on select formal intergovernmental organizations (IGOs) and possibly nongovernmental organizations (NGOs), emphasizing structures, charters, mandates, and functions. Either choice could lead one to utilize recent literature on IGOs (and to a lesser extent NGOs) as organizations and bureaucracies, examining their design, functions, and performance or behavior. Another is the extent to which various international relations as well as IO-related theories such as theories of cooperation, regime and institution formation and evolution, functionalism, constructivism, and others are integrated into an IO course. To what extent are students introduced to currents of critical theory such as postmodernism, Marxism, feminism, and postcolonialism in relationship to IOs? There is also the question of which IGOs—global and/or regional—to include given the range of possibilities. How all the abovementioned issues are addressed will strongly influence choices with regard to textbooks, other readings, and various types of electronically available materials.
