Studies about globalization and internationalization demonstrate different attitudes in explaining these concepts. Since there is no consensus among Iranian specialists about these concepts, the purpose of this study is to explain the concepts of internationalization and globalization in Iran.This study is a systematic review done in the first half of 2016. To explain the concept of globalization and internationalization, articles in Scientific Information D atabase, Magiran database, and Google Scholar were searched with the keywords such as globalization, scientific exchange, international cooperation, curriculum exchange, student exchange, faculty exchange, multinational cooperation, transnational cooperation, and collaborative research. Articles, used in this study, were in Persian and were devoted to internationalization and globalization between 2001 and 2016. The criterion of discarding the articles was duplicity.As many as 180 Persian articles were found on this topic. After discarding repetitive articles, 64 remained. Among those, 39 articles mentioned the differences between globalization and internationalization. Definitions of globalization were categorized in four categories, including globalization, globalizing, globalization of higher education, and globalizing of higher education. Definitions about internationalization were categorized in five categories such as internationalization, internationalization of higher education, internationalization of the curriculum, internationalization of curriculum studies, and internationalization of curriculum profession.The spectrum of the globalization of higher education moves from dissonance and multipolarization to unification and single polarization of the world. One end of the spectrum, which is unification and single polarization of the world, is interpreted as globalization. The other side of the spectrum, which is dissonance and multipolarization, is interpreted as globalizing. The definition of internalization is the same as that of globalizing. In other words, it is possible to say that internalization is similar to globalizing but different from globalization.
