文章内容を他者に説明する意識が日本語の文章理解に及ほす影響 : 中国語を母語とする上級日本語学習者を対象とした読解前教示操作による検討

Explanation expectancy is the expectation that a person will explain the contents of a text to another person after reading it him/herself. This study aimed to investigate whether explanation expectancy improves a deeper level of text comprehension by Chinese native speakers who are advanced learners of Japanese. I also investigated whether the individual receiving the explanation-a junior high school or college student-plays a role in reading comprehension. The 46 Chinese participants were divided into three groups: 17 participants for explanation expectancy to a junior high school student group. 14 participants for explanation expectancy to a college student group and 15 participants for test expectancy group. All the participants read a Japanese text. They answered three types of comprehension questions about the text. and they gave their ratings (on a five-point scale) to all sentences of the text with respect to how important they believed it to be to the expected explanation. From the results, it was evident that neither explanation expectancy nor the type of target individual had a significant impact on the participants' reading comprehension. However. the group that were expecting to provide an explanation to a junior high school student rated the summary part of the text as being of higher importance than the test expectancy group. This suggests that explanation expectancy may affect information structuring during the reading of L2 texts.
