Motion Lexicon: A Corpus-Based Comparison of English Textbooks and University Entrance Exams in Turkey

Abstract

This study analyzed the overlap of motion lexicon, namely manner and path verbs’ frequency profiles, in English high school textbooks (9th-12th grade) and English university entrance exams (2010-2019) in Turkey through AntwordProfiler, a corpus linguistic tool. The manner verbs were sampled from Levin’s study (1993) while the path verbs were gathered from Talmy’s book (2001). The frequency of motion verbs in official teaching materials was compared with their frequency in exam materials using SPSS. The results indicate that the mismatch of motion verbs between the textbook and exam corpora is statistically significant in terms of manner verb frequency levels (p < .000). While path verbs scored, on average, higher in descriptive statistics in the textbook corpus, there was no statistical significance observed. The findings suggest that whenever the students take English exam, they may be more likely to be under a higher cognitive load and may be forced to develop the negative backwash effect since what is taught is not tested. This, consequently, raises concerns regarding the content validity of exams and other issues related to the reliability and validity of the national English exams. The findings of this study have implications for material developers and test takers.
