The study scrutinizes the intermodal relations and interactive meaningmaking of the textual and visual semiotics involved in modern technology representation, which indicates the engagement of authentic communication in language learning. The findings show that both textbooks show attempts to capture the up-to-date technology of modern life. Learners tend to be involved with the interpretation of the indexical relations between the visual and textual resources in one textbook, while the other textbook consists of a few texts and images that are not indexically related and are less likely to be interpreted interactively. Findings indicate the importance of being aware of the different emphases of these two textbooks through multimodal research, for the purpose of effective adaptations in CFL teaching and learning.
