In this paper we review our class activities using The Intersection of Arts, Humanities, and Science (2020), which was coauthored by the members of The Japan Association of International Liberal Arts with the aim of integrating content and language learning according to the concept of CLIL (Content and Language Integrated Learning). The book includes not only topics to stimulate university students'intellectual curiosity but also various activities through which students can read, think, and express themselves in English. Based on our reflective review of class activities and student samples, we discuss possible pedagogical effects and further improvements of CLIL.
