"In order to cultivate students to become educators with intercultural competences, this researcher adopted the action research method to integrate intercultural competences into the Master’s course of “Studies in Adult Education for International Marriage Immigrants” in a university taught by the researcher. There are a total of 6 participants in the course. The purposes of this study are to explore what intercultural competences students gained in this course? And what curriculum and teaching designs and implementations help foster intercultural competences? As a result, this study found that, first of all, this course helps improve students' intercultural competences. Students’ learning starts from breaking down stereotypes about international immigrants and improving their understanding of the knowledge related to marital immigration, which in turn leads to empathy and multicultural thinking. Secondly, this course develops a SPA framework that includes three components: cognitive scaffold, discussion platform, and action plans to aid the implementation of the teaching strategy of problem-based learning. Cognitive scaffold helps students understand adult education for international marriage immigrants from a broad social and cultural context. The discussion platform functions to break down stereotypes and re-establish new perspectives. Action plans help to build students’ learning meanings and integrate what have been learned in the classroom. Finally, this study puts forward a number of recommendations for future teaching and research references."
