Abstract

Critical thinking skills are very much needed in science learning in this information era. The purpose of this study is to determine the effect of the Search, Solve, Create, and Share (SSCS) learning model on students' critical thinking skills. This type of research is quantitative, with a Quasy Experiment research design in the form of a posttest control group design. Sampling was carried out using a random sampling technique with class VII.3 as the experimental class and VII.2 as the control class. The assessment carried out was on students' critical thinking skills using a posttest in the form of an essay of 15 questions. From the results of the study, it was obtained that students' critical thinking skills in the experimental class with the highest explanation indicator were 89.39% in the high category, and the control class with the inference category were 73.86% in the medium category. After testing the hypothesis with the t-test, a significance result of 0.021

Abstract

Penelitian ini dilaksanakan karena kemampuan literasi sains siswa masih belum mencapai rata-rata PISA melalui program OECD. Rendahnya literasi tersebut dipengaruhi oleh penggunaan media pembelajaran yang kurang variatif serta rendahnya minat belajar peserta didik. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan media pembelajaran Google Sites pada materi Klasifikasi Makhluk Hidup terhadap literasi sains digital siswa kelas X SMAN 3 Palangka Raya. Penelitian ini menerapkan penelitian eksperimen dengan desain penelitian kuasi yang dilakukan pada semester ganjil tahun ajaran 2025/2026 di SMA Negeri 3 Palangka Raya dan sampel penelitian melibatkan 80 siswa kelas X. Uji coba instrumen dilakukan pada 44 siswa kelas XI. Instrumen berupa tes literasi sains yang telah melalui proses validasi, dan dari 100 butir soal valid diperoleh koefisien reliabilitas sebesar r₁₁ = 0,92 yang menunjukkan tingkat reliabilitas sangat tinggi. Hasil uji hipotesis menggunakan uji-t menunjukkan nilai thitung sebesar 2,89, sedangkan ttabel pada taraf signifikansi 5% (α = 0,05) sebesar 1,99. Karena thitung lebih besar daripada ttabel (2,89 > 1,99), maka hipotesis alternatif (Ha) diterima dan hipotesis nol (H₀) ditolak. Berdasarkan hasil tersebut dapat disimpulkan bahwa penggunaan media pembelajaran Google Sites memberikan pengaruh positif terhadap peningkatan literasi sains digital siswa pada materi klasifikasi makhluk hidup di kelas X SMAN 3 Palangka Raya.

Abstract

This study aimed to describe students’ scientific reasoning assessment experiences in high school biology learning. The study employed a descriptive quantitative method involving 216 eleventh-grade students from A- and B-accredited senior high schools in Bandung and Cimahi. Data were collected through assessment experience questionnaires using a Likert scale and semi-structured interviews as supporting data. Data analysis was conducted descriptively for each sub-element of assessment experience. The results showed that students’ assessment experiences were categorized as moderately good, with score ranges from 2.41 to 2.77. The highest scores were found in assessments measuring scientific reasoning types as well as social and technological contexts, while the lowest scores were found in controlled experimental design. Interview results indicated that biology assessments had begun to incorporate real-life contexts and data analysis; however, assessment experiences based on scientific investigation were still not evenly implemented.

Abstract

Diabetes mellitus is a noncommunicable disease with a high prevalence rate that is known to be closely linked to genetic factors. This study aims to examine the patterns of genetic inheritance of diabetes mellitus across three generations with a history of the disease. The methods used in this study were qualitative descriptive techniques, including interviews, observations, and pedigree analysis, to track the distribution of diabetes mellitus across generations. The results indicate that diabetes mellitus follows an autosomal dominant inheritance pattern, as evidenced by the presence of affected individuals in nearly all generations regardless of gender. The highest percentage of patients was found in Family B at 41.7%, followed by Family C at 29.2%, and Family A at 17.6%. These findings confirm that genetic factors play a significant role in the transmission of diabetes mellitus across generations, although environmental and lifestyle factors also contribute to the onset of this disease

Abstract

This study aimed to develop and evaluate the effectiveness of a Problem-Based Learning (PBL) model integrated with the local wisdom of South Nias, known as Hombo Batu (traditional stone jumping), in enhancing secondary school students' scientific attitudes and physics problem-solving abilities. The study employed a Research and Development (R&D) approach using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) framework and was conducted in South Nias Regency, North Sumatra, Indonesia. The developed instructional materials, comprising a model book, teacher's guide, student book, and ethnophysics-based student worksheets, were subjected to expert validation and field testing. The effectiveness of the model was evaluated through a quasi-experimental pretest–posttest control group design involving 68 junior high school students, divided equally into experimental and control groups. Data were analyzed using normalized gain (N-gain) and Multivariate Analysis of Variance (MANOVA). The results indicated that the developed instructional materials achieved a high validity score of 93.6%. Regarding physics problem-solving abilities, the experimental group attained an N-gain of 0.73, classified as high, compared with 0.41, classified as moderate, in the control group. Furthermore, the experimental group achieved a mean scientific attitude score of 86.50%, indicating a very high category. MANOVA results revealed a statistically significant multivariate difference between the experimental and control groups in the combined outcome variables (p < 0.001). These findings demonstrate that integrating Hombo Batu ethnoscience into the PBL framework provides a promising pedagogical approach for connecting indigenous cultural knowledge with abstract physics concepts. The developed model supports contextualized scientific learning while promoting physics problem-solving abilities and positive scientific attitudes. This study highlights the potential of indigenous local wisdom as a meaningful foundation for developing culturally responsive and contextually relevant physics education
