  • 日本の大学英語授業におけるTOEICクラス内で小テストの波及効果を媒介する要因

    2023  

    　View Summary

    The washbackeffect, which refers to the impact of tests on teaching and learning, is asignificant topic in language testing. However, existing research on thewashback effect has primarily focused on large-scale tests, with limitedattention given to the impact of small-scale tests in classroom settings. Therefore,this study investigates the effects of quizzes in Japanese university TOEIC Listening& Reading Test (hereafter TOEIC) courses.One of thecharacteristics of the impact of quizzes in university TOEIC courses, withinthe framework of washback studies, is the dual influence observed—both from theTOEIC on learners and from quizzes within the context of TOEIC andlearners. While previous studies have addressed washback studies of the TOEIC, no studies have not discussed simultaneously both the direct impact ofin-class TOEIC quizzes, situated between TOEIC and learners, and the indirectimpact of large-scale tests like the TOEIC, which underlies the direct impactof the TOEIC. Given the context-specific nature of the washback effect, it isimperative first to comprehend the learning environment in which quizzes areadministered in university TOEIC classes.This studyfocuses on quizzes in Japanese university TOEIC classes and identifies thefactors mediating classroom quizzes’ washback effect. The participants wereprivate university students in the Kanto area in Japan enrolled in TOEICcourses where vocabulary and grammar quizzes were conducted. Many studentsparticipated in a two-semester TOEIC course for one year, taking grammar orvocabulary quizzes every 10 weeks. The format of the quizzes involved multiplechoice questions for grammar tests and matching exercises for vocabulary tests,respectively. This study employed an open-ended questionnaire and conductedinterviews with a participant to explore the factors mediated by the quizzesand their surroundings in TOEIC courses. The questionnaire content, interviewquestions, and subsequent analysis were informed by the categorization offactors in the washback effect established in previous studies, includingspecificity, intensity, length, intentionality, and value.The study’sfindings suggest potential mediating factors for future investigations of TOEICquiz washback, such as the weekly study workload, familiarity with the quizformat, and the sequence of experiencing vocabulary and grammar quizzes. This studyprovides a way to conduct future studies by capturing the varying degrees ofimpact of both TOEIC quizzes and the TOEIC.

    　View Summary

    As of 2022, external tests are used inparallel with the in-house tests developed individually by each university for Englishlanguage university entrance examinations in Japan. However, for universitiesto select and use appropriate external tests, it is desirable to understand thepurpose of the test development and construct of each external test used in conjunctionwith the in-house test, and to compare and contrast them with their in-house test.At the same time, empirically understanding the test contents is the first steptoward predicting the washback effects of using each test, i.e., the impact ofthe tests on teaching and/or learning. Therefore, this study conducted a testcontent analysis of external tests used at several universities. The analysiswas conducted using the framework of language assessment theory.
