The document discusses the changing roles and training of teachers. As the goals of education change, so do expectations of teachers. Teacher education programs must adapt to prepare teachers for diverse student needs, including students from varying cultures or backgrounds. There is also pressure to align teacher training with the demands of the global economy. The teacher shortage provides an opportunity to tighten certification standards and control education curricula. Reasons for the shortage include increasing student populations and more lucrative careers in other fields. The document debates whether teacher training and licensing should be determined by testing or labor market needs.
