Speech delays are a developmental challenge often experienced by young children, which can affect their communication skills and social aspects. This research aims to explore the effectiveness of applying visual and audio media in improving the language skills of young children who experience speech delays. The visual media used are picture flashcards, interactive videos and picture story books, while the audio media is children's music, voice recordings and regional songs. This research was conducted at a language therapy center in Indonesia with a case study approach on 10 children aged 3–5 years. The research results show that the combination of visual and audio media can significantly increase children's attention, vocabulary understanding and speaking abilities. The use of local culture-based media such as regional songs also has a positive impact by creating a sense of relevance and emotional closeness. In addition, active involvement of parents in this process increases the success of the intervention. This research recommends consistent application of visual and audio media as part of local context-based therapy to support the language development of children with speech delays. 

Education in the era of globalization demands the development of students' social skills, including collaboration, to prepare them for the challenges of the 21st century. One effective method to train these skills is small group discussions, which encourage students to share ideas, listen to other perspectives, and reach consensus. This study aims to identify effective strategies in guiding small group discussions to improve student collaboration, focusing on the implementation of the Merdeka Curriculum. The research method used is qualitative descriptive with a case study design in one of the high schools that implements the Merdeka Curriculum. Data were collected through observation, interviews, documentation, and student collaboration questionnaires. The results of the study indicate that effective strategies include the use of open-ended questions, providing constructive feedback, and dividing roles in groups. In addition, the dynamics of small group discussions can be improved with good conflict management by teachers. This study also found that small group discussions can improve students' collaboration skills, which are reflected in communication, individual responsibility, and group decision making. Implications for the implementation of the Merdeka Curriculum show the importance of teacher training to improve the ability to guide small group discussions effectively. This study provides practical and theoretical contributions to the development of collaboration-based learning in Indonesia.
