Abstract

Down Syndrome causes intellectual disabilities and language delays, especially expressive language. Children with Down Syndrome require concrete and easy-to-understand learning media. Augmentative and Alternative Communication (AAC), specifically AVAZ AAC. This media has features that can offer effective support. This study aims to analyze the effectiveness of AVAZ AAC in improving the expressive language skills of children with Down Syndrome in Surakarta. This research is a quantitative descriptive study with a quasi-experimental design using a one-group pre-test–post-test approach on 10 children with Down Syndrome who were selected purposively. The intervention consisted of 6 sessions. Expressive language skills were measured using the NSST. Data were analyzed using a Paired t-test and Cohen's d effect size. The average score increased from 6 to 16.3, with a change in category from entirely low to mostly moderate. The Paired T-Test produced p = 0.001, and effectiveness was declared strong with an effect size of Cohen's d = 1.43, indicating a significant influence of AVAZ AAC media. The use of AVAZ AAC media has been proven effective in improving the expressive language skills of children with Down Syndrome, as evidenced by changes in score categories, a p-value of 0.001, and a large effect size (d = 1.43). This media is recommended for continued use by parents, teachers, schools, and therapists, and supported by ongoing research with a larger sample size and extended duration.

Abstract

Abstrak Autism Spectrum Disorder (ASD) adalah gangguan perkembangan saraf yang ditandai dengan kesulitan dalam komunikasi sosial, termasuk memulai interaksi, mempertahankan percakapan, dan merespons dengan tepat dalam situasi sosial. Salah satu media instruksional yang dapat mendukung pengembangan keterampilan ini adalah Kartu Aktivitas Sosial, yang memberikan stimulasi visual dan kegiatan terstruktur untuk membantu anak-anak lebih memahami konteks sosial. Penelitian ini bertujuan untuk mengkaji efektivitas Kartu Kegiatan Sosial dalam meningkatkan keterampilan komunikasi sosial pada anak dengan ASD. Penelitian ini menggunakan metode kuasi-eksperimental menggunakan desain pretest-posttest satu kelompok. Peserta terdiri dari lima anak dengan ASD berusia 10-11 tahun, dipilih melalui purposive sampling. Intervensi dilakukan selama delapan sesi menggunakan Kartu Kegiatan Sosial. Keterampilan komunikasi sosial diukur sebelum dan sesudah intervensi, dan data dianalisis menggunakan uji-t sampel berpasangan. Temuan ini mengungkapkan peningkatan yang signifikan dalam keterampilan komunikasi sosial setelah intervensi. Rata-rata skor pretest 42,40 meningkat menjadi 61,60 pada posttest. Analisis statistik menunjukkan nilai Sig. (2-tailed) 0,003 (p < 0,05), menunjukkan bahwa hipotesis nol ditolak dan hipotesis alternatif diterima. Selain itu, nilai t yang dihitung (–6,386) melebihi nilai tabel t kritis pada df = 4 (2,776), mengkonfirmasi perbedaan yang signifikan antara hasil pretest dan posttest. Temuan ini menunjukkan bahwa Kartu Aktivitas Sosial efektif dalam meningkatkan keterampilan komunikasi sosial pada anak-anak dengan ASD. Kata Kunci: Anak Autis, Komunikasi Sosial, Social Activity Card Abstract Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder marked by difficulties in social communication, including initiating interactions, maintaining conversations, and responding appropriately in social situations. One instructional medium that can support the development of these skills is the Social Activity Card, which provides visual stimulation and structured activities to help children better understand social contexts. This study aimed to examine the effectiveness of Social Activity Cards in improving social communication skills in children with ASD. The research employed a quasi-experimental method using a one-group pretest–posttest design. Participants consisted of five children with ASD aged 10–11 years, selected through purposive sampling. The intervention was conducted over eight sessions using Social Activity Cards. Social communication skills were measured before and after the intervention, and the data were analyzed using a paired samples t-test. The findings revealed a significant improvement in social communication skills following the intervention. The mean pretest score of 42.40 increased to 61.60 in the posttest. Statistical analysis showed a Sig. (2-tailed) value of 0.003 (p < 0.05), indicating that the null hypothesis was rejected and the alternative hypothesis was accepted. Additionally, the calculated t-value (–6.386) exceeded the critical t-table value at df = 4 (2.776), confirming a significant difference between pretest and posttest results. These findings demonstrate that Social Activity Cards are effective in enhancing social communication skills in children with ASD.
