Abstract

The twenty-first century is marked by rapid transformations driven by advances in science and technology, which significantly influence human competition and global development. In this era, science literacy has become one of the 16 essential skills identified by the World Economic Forum as crucial competencies for students. Science literacy is defined as the ability to apply scientific knowledge, identify questions, and draw conclusions based on evidence to understand natural phenomena and make informed decisions about the impact of human activities on the environment. This study employed a quantitative descriptive research method aimed at analyzing the profile of students’ science literacy skills based on competency indicators in learning environmental pollution material. The research subjects consisted of 64 students from two classes. Data collection was conducted using a test instrument based on OECD science literacy competencies, which included five indicators with a total of ten questions. The findings revealed that the highest average achievement was in identifying questions within scientific investigations, reaching 73.96%. In contrast, the lowest achievement was in transforming data between representations, with 50.45%. Overall, the average score across all indicators was 60.91%, categorized as moderate level.

Abstract

Keterampilan berpikir kritis menjadi keterampilan yang esensial untuk dilatihkan di abad ke-21. Namun, hasil penelitian menunjukkan implementasi keterampilan berpikir kritis peserta didik masih di bawah rata-rata. Kondisi ini dapat berdampak pada lemahnya kemampuan memecahkan masalah, khususnya pada materi Biologi yang bersifat kompleks dan abstrak seperti sistem saraf dan indera. Untuk menjawab tantangan tersebut, diperlukan media pembelajaran inovatif yang mampu memfasilitasi keterlibatan peserta didik dalam proses belajar. Salah satunya adalah e-modul interaktif yang menerapkan sintaks discovery learning, sehingga praktis mendorong peserta didik dalam menemukan konsep materi karena menekankan proses berpikir kritis dan analisis. Oleh karena itu, tujuan penelitian adalah mengembangkan e-modul interaktif berbasis discovery learning yang layak secara teoretis (valid) dan empiris (praktis) dalam melatihkan keterampilan berpikir kritis pada materi sistem saraf dan indera. Penelitian menggunakan model 4D (define, design, develop, dan disseminate) dengan subjek penelitian sebanyak 36 peserta didik kelas XI SMAN 21 Surabaya. Kelayakan teoretis diperoleh dari uji validasi oleh tiga validator, sedangkan kelayakan empiris didapatkan melalui dua uji kepraktisan, yaitu keterlaksanaan sintaks discovery learning oleh dua observer dan angket respons peserta didik. Hasil penelitian kemudian dianalisis secara deskriptif kuantitatif. Hasil uji validasi memperoleh persentase 93,83% untuk kategori sangat valid. Hasil observasi keterlaksanaan sintaks discovery learning menghasilkan persentase 91,2% tergolong kategori terlaksana, serta hasil angket respons menunjukkan persentase 96,4% termasuk kategori praktis. Dengan demikian, e-modul interaktif berbasis discovery learning dinyatakan layak secara teoretis dan empiris dalam melatihkan keenam indikator keterampilan berpikir kritis menurut Facione (interpretasi, analisis, inferensi, eksplanasi, evaluasi, dan regulasi diri) peserta didik materi sistem saraf dan indera.

Abstract

Critical thinking skills are higher-order thinking skills that are essential to be developed in biology learning. This development research aimed to produce a Problem-Based Learning (PBL)-based electronic student worksheet (E-LKPD) on the respiratory system topic to improve students’ critical thinking skills, which is feasible in terms of validity, practicality, and effectiveness. The development of the E-LKPD employed the 4D model consisting of define, design, develop, and disseminate stages. The product trial was conducted on 36 eleventh-grade students of SMAN 14 Surabaya. The parameters measured in this study included validity assessed by experts, practicality based on the implementation of learning activities and students’ responses, and effectiveness based on the improvement of students’ critical thinking skills from pretest and post-test results. The data were analyzed using descriptive quantitative methods. The results showed that the developed E-LKPD obtained a validity score of 98.75%, categorized as very valid. The practicality of the E-LKPD based on the implementation of learning activities reached 98.5%, while students’ responses reached 97.8%, both categorized as very practical. The effectiveness of the E-LKPD was indicated by the improvement of students’ critical thinking skills with an N-Gain score of 0.74 which falls into the moderate category.
