Can second language metaphorical competence be taught through instructional intervention? A meta-analysis

Abstract

BackgroundFor a long time, the traditional view regarded metaphor as merely a rhetorical device that served to enrich linguistic expression. With the continuous development of cognitive linguistics, foreign language educators began to realize the vital role of metaphor in foreign language education.ObjectivesThis study looked at how well pedagogical interventions improve metaphorical competence by looking at how well teachers teach metaphors.MethodsAfter a rigorous literature search and selection process from the Chinese and English databases, 13 Chinese and 7 international studies with 51 effect sizes were included in this meta-analysis. With the help of the meta-analysis 3.0 software, the literature and heterogeneity tests were performed to ensure that the meta-analysis results were as accurate and valid as possible.ResultsThe effect size tests revealed that the metaphorical instructional intervention was significantly effective in general and produced a large effect size (d = 0.888) on improving learners' metaphorical abilities. Meta-regression analyses were also conducted to examine how other factors might change the effects of the interventions.FindingsResearch has shown that instructional interventions that combine prolonged input of metaphorical concepts with reinforcement of metaphorical practice can help second language learners develop metaphorical competence. Teaching puts more pressure on teachers and the learning environment, and the results of this study could help teachers teach metaphors in the future.
