Abstract

Tujuan penelitian adalah menguji efektivitas model discovery learning berbantuan website untuk meningkatkan kemampuan berpikir kritis dan mendeskripsikan kemampuan berpikir kritis ditinjau dari Adversity Quotient. Metode penelitian menggunakan mix method. Desain eksperimen menggunakan pretes-posttest control group design dengan sampel kelas VIII. Sampel penelitian terdiri dari dua kelas yaitu kelompok eksperimen dan kelompok kontrol. Teknik pengumpulan data yang digunakan yaitu tes, angket, dan wawancara. Data yang diperoleh dianalisis secara kuantitatif dan secara kualitatif. Hasil penelitian menunjukkan bahwa model discovery learning berbantuan website efektif untuk meningkatkan kemampuan berpikir kritis yang ditunjukkan dari hasil tes pada kelompok eksperimen lebih dari KKTP yaitu 80, proporsi hasil tes pada kelompok eskperimen yang melebihi KKTP telah lebih dari 75%, rata-rata hasil tes pada kelompok eskperimen lebih dari kelompok kontrol, proporsi hasil tes peserta didik pada kelompok eskperimen lebih dari kelompok kontrol, peningkatan rata-rata pada kelompok eksperimen dalam kategori tinggi sedangkan kelompok kontrol dalam kategori sedang, dan terdapat pengaruh Adversity Quotient terhadap kemampuan berpikir kritis sebesar 74,1%. Deskripsi kemampuan berpikir kritis menunjukkan subjek tipe climber mampu memenuhi indikator clarification, assesment, strategy, dan inference, sedangkan subjek dengan tipe camper hanya memenuhi indikator clarification dan assesment.

Abstract

Deaf students face challenges in understanding abstract mathematical concepts, especially the material of data concentration measures, due to limited verbal communication and lack of learning media that suits their characteristics. This study aims to examine the effectiveness of statistical e-comic based on multisensory approach integrated with collaborative learning model in improving mathematical connection ability of deaf students. The research approach used is mixed-methods with Single Subject Research (SSR) design type A-B-A. The subjects consisted of three deaf students of class VIII-B in SLB Negeri Ungaran who were purposively selected. Data collection techniques included mathematical connection tests, learning observations, semi-structured interviews, and visual documentation. Quantitative data was analysed using visual inspection charts within and between conditions, while qualitative data was analysed through reduction, presentation, interpretation, and conclusion drawing. The results showed that statistical e-comic media was effective in significantly improving deaf students' mathematical connections, both from cognitive (concept understanding), affective (motivation and attitude), and psychomotor aspects (digital skills and participation). The conclusion shows that statistical e-comic with multisensory approach and collaborative learning is able to bridge the gap of mathematical understanding contextually and applicatively.
