This study aimed to assess the effectiveness of metacognitive methods in college general English classes to improve students’ communication skills and metacognitive awareness. The approach involved structuring learning activities where students adapted movie dialogues, practiced roles, collaborated with peers, and received feedback on problemsolving. The results showed significant improvements in speaking skills, with preassessment scores of 24.79 increasing to 27.17 in the post-assessment (p < .01). These findings indicate notable gains in fluency and accuracy in English communication, as well as improved attitudes towards the language. Although there were improvements in post-assessment scores for metacognitive processes, these changes were not statistically significant. This study highlights the importance of incorporating diverse learning methods into college general English classes, particularly emphasizing the value of metacognitive techniques. These methods help students apply classroom learning to realworld social situations and enhance their communication abilities.

Prevalence of children with developmental disabilities has increased the need for a variety of educational and therapeutic interventions for children in the study of the subject has increased according to the load. in this paper, the review of the developmental disability characteristics and teaching methods are based on this proposal of realistic experimental serious game contents using AAC(Augmentative and Alternative Communication) method because we make up for the conventional interventions and increase participation and motivation in learning. In this paper, we improve the area said to be the motivation and commitment to develop the content by using a realistic experience for users experiencing at present a pervasive developmental disorder of language development in the paper.
