This study examined the effect of explanation to others in Japanese, a second language, during a listening comprehension lecture for Chinese advanced learners of Japanese. The factors were the purpose of listening and the listening ability in listening comprehension test. Task performance, after listening to a lecture, was used to measure the degree of comprehension representation formation. As a result, it was found that after receiving explanation to others in a second language, learners with low listening comprehension could construct text-based representations to the same extent as learners with high listening comprehension. Additionally, there was no difference in the degree of representation formation irrespective of listening comprehension capacity. These results suggest that explanation to others, irrespective of the listening comprehension capacity, facilitates the construction of situation model.
