This two-year action research study examines how incorporating ‘The Writing Revolution’ (TWR) strategies and adapting task complexity can improve TESOL students' expository writing in secondary education in Cyprus. A total of eighty-three students (12-17 years old) from various first language (L1) backgrounds and CEFR levels (A1-B2) participated from six lower secondary (LS) and upper secondary (US) state classrooms. The methodology involved spending one-quarter of students' weekly class time on the learning and application of TWR techniques in their L2/EFL writing. Overall, 90-180 activities were completed successfully, and cognitively undemanding and context-embedded writing tasks gave way to more complex and cognitively demanding tasks to suit students’ differing proficiency levels. Qualitative analysis of students’ writing and focus group discussions indicated that writing improved coherence, organization, and complexity. Students expressed feelings of reduced anxiety and improved confidence in English writing. These findings highlight the importance of dedicating time to teaching writing explicitly in L2/FL classrooms and gradually increasing task complexity beginning at the sentence level. This study’s unique contribution demonstrates how TWR strategies can be effectively tailored to L2/FL contexts and offer practical implications for TESOL curriculum developers, researchers, and educators seeking to improve students’ writing confidence in FL and lessen writing anxiety in the classroom.

Duolingo has become one of the most widely used gamification apps for learning English, mostly for vocabulary and grammar. However, there is limited research on its effectiveness in enhancing writing skills. This study aimed to investigate the effect of Duolingo on junior high school students' learning English as a Foreign Language (EFL) writing skills, focusing on the overall score and five components: content, organization, vocabulary, language use, and mechanics. The study used a quasi-experimental design, specifically the non-equivalent control group, involving 41 eighth-grade students in experimental and control groups. Both groups were assigned writing tests as a pre-test and a post-test. The experimental group received an intervention using Duolingo outside the classroom for eight weeks as a supplementary tool, while the control group only received regular English classes. The statistical analysis using the independent t-test and ANCOVA revealed a significant improvement in writing skills in the experimental group (p < .05). It also showed an improvement in all writing components, especially content and organization. The partial eta squared value indicated a large effect of Duolingo (η²p = .878). These findings suggest that Duolingo has the potential to serve as a supplementary tool for improving writing skills in language learning.
