Language teachers use group work in their lessons for various purposes, such as promoting student interaction and collaboration, developing communication and language skills, providing opportunities for peer feedback and support, and enhancing critical thinking and problem-solving abilities. According to a study conducted in a Swedish school, group work was found to be an effective way to engage students in learning English and modern languages, as it allowed for more active and engaging participation, enabled students to learn from each other and take responsibility for their own learning, and created a supportive and inclusive classroom environment. Evaluating group work in learning English can involve various methods, such as assessing individual contributions and participation, monitoring group dynamics and interactions, providing feedback and reflection opportunities, and using rubrics or checklists to evaluate specific language skills and competencies.
