Expanding Vocabulary through Quizlet to Improve Students’ Writing

Abstract:

This research reports the expansion of technical vocabulary through group work facilitated by Quizlet to improve students’ writing. This study was conducted at a public technological institute. It involved ten students from the Plastic school. They had to reach a B1.2 level of English to decode books and fill out forms. However, they were an A1 level and they could not write simple sentences. With this previous information, this innovation was carried out. The study addressed three research questions: 1. To what extent will the introduction of CLIL improve students’ writing of simple sentences using technical vocabulary? 2. Will group work improve students’ technical vocabulary range? 3. What are students’ perspectives towards the innovation? A pretest, a posttest, a survey, and a rubric answered these questions. The data determined a significant and notable expansion of vocabulary. Students’ writings also improved. At the end of the innovation, the data analyzed showed a large effect size of Cohen’s d = 0.85. The results suggested that this action research may be helpful for technical students, researchers, and authorities who want to improve writing through the expansion of vocabulary.
