Improvement of EFL writing skills through cooperative learning strategies

Abstract

Abstract: This study aimed to determine the effects of cooperative learning strategies, Jigsaw and STAD, on EFL writing skills. This research was conducted in a public secondary school in Loja, Ecuador, and employed a mixed methods approach, including quantitative and qualitative analyses. The sample for this study consisted of thirty high school students and one EFL teacher. The instruments used during the data collection phase included pre- and post-tests of writing skills scored with an analytical rubric and a survey on students perceptions of cooperative learning strategies. The results revealed that cooperative learning strategies, particularly Jigsaw and STAD, significantly improved students writing skills in several aspects, such as content, vocabulary, grammar, and mechanics. The organizational aspect improved, but remained a challenge. The students overwhelmingly perceived the strategies as beneficial, as they fostered collaboration, peer support, and personal responsibility.
