the effectiveness of using wordup in enhancing efl learners’ vocabulary learning: a corpus-based mobile app

The present study was an attempt to investigate the possible effect of using wordup software on iranian efl learners’ vocabulary learning. the participants were 60 upper-intermediate efl learners who were selected out of 72 based on the oxford proficiency test. then, the participants were randomly divided into two groups of study namely experimental and control. the participants in the experimental group underwent an eight-session treatment including learning vocabulary based on using wordup software. in the control group, however, the participants gained new vocabulary by conventional methods. the quantitative approach employed a quasi-experimental method to obtain pre-test and post-test results from learners in both the experimental and control groups. the results of the study revealed that using wordup software caused a considerable improvement in learning the vocabulary among the learners in the experimental group. the findings of this study could benefit language learners, language teachers, and curriculum developers by providing valuable insights into vocabulary acquisition through wordup for efl learners.
