Abstract

Penelitian ini bertujuan menganalisis dan membandingkan kualitas umpan balik ChatGPT 5.5 dan DeepSeek V4 terhadap jawaban kontekstual siswa pada konsep optik fisika. Penelitian menggunakan pendekatan campuran dengan desain explanatory sequential. Data diperoleh dari 20 siswa yang mengerjakan enam soal kontekstual optik fisika. Setiap jawaban siswa diberi umpan balik oleh ChatGPT 5.5 dan DeepSeek V4 sehingga diperoleh 240 unit umpan balik AI. Kualitas umpan balik dinilai berdasarkan empat indikator, yaitu akurasi ilmiah, kedalaman penjelasan, relevansi terhadap konteks jawaban siswa, dan kejelasan bahasa. Data kuantitatif dianalisis menggunakan statistik deskriptif, uji normalitas, dan Wilcoxon Signed-Rank Test, sedangkan data kualitatif dianalisis melalui telaah isi umpan balik. Hasil penelitian menunjukkan bahwa ChatGPT 5.5 memperoleh mean total 15,31 atau 95,68%, sedangkan DeepSeek V4 memperoleh mean total 14,68 atau 91,77%. Keduanya berada pada kategori sangat baik. Uji Wilcoxon menunjukkan perbedaan signifikan pada akurasi ilmiah, kedalaman penjelasan, relevansi terhadap konteks jawaban siswa, dan total skor, sedangkan kejelasan bahasa tidak berbeda signifikan. Analisis kualitatif menunjukkan bahwa ChatGPT 5.5 lebih stabil dalam memberikan koreksi konseptual yang akurat, mendalam, dan relevan, sedangkan DeepSeek V4 tetap kuat pada kejelasan bahasa tetapi lebih bervariasi pada substansi isi. Dengan demikian, perbedaan utama kedua model terletak pada kualitas isi umpan balik, bukan pada aspek kebahasaan. Temuan ini memberikan bukti empiris bahwa ChatGPT 5.5 lebih unggul dalam menghasilkan umpan balik yang akurat, mendalam, dan sesuai dengan konteks jawaban siswa, sedangkan DeepSeek V4 menunjukkan performa yang kompetitif terutama pada aspek kejelasan bahasa. Hasil penelitian ini dapat menjadi pertimbangan bagi pendidik dalam memilih dan memanfaatkan AI generatif sebagai pendukung asesmen formatif pada pembelajaran fisika.

Abstract

Critical thinking skills are important in physics education because they encourage students to analyze, evaluate, and apply concepts in real life. However, the assessment instruments used still focus on memory skills and have not integrated the local cultural context. In fact, many physical phenomena, including heat transfer, can be seen in cultural activities such as traditional food preparation. Previous studies have emphasized the development of questions based on higher-order thinking skills, literacy, and numeracy, but few have linked them to culture. Therefore, it is necessary to develop ethno-physics-based critical thinking questions on heat so that assessments not only measure conceptual mastery but also connect physics with local wisdom. This study aims to analyze the validity, reliability, discriminating power, and difficulty level of ethno-physics-based critical thinking questions on the topic of heat, as well as to test their practicality. The method applied is Tessmer's Research and Development (R&D) model, with stages including Preliminary, Self-Evaluation, and Formative Evaluation. The results of the development show that the resulting test items are valid. The reliability value obtained is 0.75, which is classified as high. In terms of difficulty, the majority of questions are categorized as moderate and a small portion are easy. The discrimination power of the test items varies between very good, good, and fair. Overall, all items successfully differentiated between students' abilities, and none of the items failed to differentiate. In terms of practicality, the use of these items is classified as very practical.

Abstract

This study aims to analyze the effect of guided inquiry-based earthquake media on the scientific literacy and critical thinking skills of elementary school students in the Petobo liquefaction-affected area, Palu City. The low scientific literacy and disaster preparedness of students after the 2018 earthquake became the basis of this study. The method used was a quasi-experimental with a Non-Equivalent Control Group design, involving 53 sixth grade students. The experimental group implemented guided inquiry learning through the creation of a simple seismograph, while the control group used conventional learning. The results showed an increase in scientific literacy and critical thinking in the experimental group was higher than the control group, with a significant difference based on statistical tests and learning effectiveness that was classified as moderate to high. It was concluded that guided inquiry-based earthquake media was more effective in improving scientific literacy and critical thinking skills of students in disaster-affected areas.
