The development of pre - service teachers’technology integration ability needs to break away from the idea of relying on a single educational technology course and integrate technology into the teacher education curriculum. Under the path of“Technology Infusion,”Arizona State University in the United States has realized the organic integration of technology and subject teaching by estab- lishing a vision and gradually promoting reform,building three pillars of technology infusion,enhancing teacher educators’ability to integrate technology,and promoting collaborative cooperation among reform stakeholders. Taking Arizona State University as a refer- ence,we should promote the conceptual change of pre - service teachers’IT teaching ability development,build a“curriculum group” for pre - service teachers’IT teaching ability development,form a“dual teacher system”for pre - service teachers’IT teaching ability development,and produce the technical ability standard of teacher educators to lead teacher training,so as to optimize the training path of pre - service teachers’information - based teaching ability.
