Understanding the constituents of a sentence plays a crucial role in understanding the structure and meaning of a sentence. However, as Kanatani et al. (2015) point out, it is difficult for Japanese secondary school students to identify these parts in English, particularly what constitutes a noun phrase (NP). Thus, we wanted to start raising awareness of sentence constituents at elementary schools. We conducted two studies that nurtured students’ understanding of what constitutes an NP in both English and Japanese using DDL (data-driven learning). Pre- and post-tests and questionnaires measured the effects of the studies on participants (70 and 68 sixth graders, respectively). The test scores revealed that students found it was easier to identify constituents in English sentences containing general verbs than those containing be-verbs. It was also observed that while initially, it was more difficult for students to identify the constituents of English sentences compared to Japanese sentences, that gap gradually narrowed as lessons proceeded. An examination of students’ notes on the DDL worksheets confirmed that placing English and Japanese side by side was an effective awareness-raising strategy.
