Abstract

ABSTRAK Penelitian ini merupakan penelitian secara komperensif dan menggunakan metode campuran (mixed method) khususnya desain sekuensial eksplanatori yang bertujuan untuk mengetahui konsep biologi yang dipersepsikan sulit oleh siswa SMA Negeri di Kabupaten Luwu Utara dan alasan konsep yang teridentifikasi sulit oleh siswa. Penelitian ini dilaksanakan di lima SMA Negeri di Kabupaten Luwu Utara yaitu SMA Negeri 1, SMA Negeri 2, SMA Negeri 3, SMA Negeri 4, dan SMA Negeri 19 pada bulan Februari 2025 tahun pelajaran 2024/2025. Populasi penelitian ini adalah seluruh siswa kelas XII SMA Negeri di Kabupaten Luwu Utara dan sampel berjumlah 158 siswa kelas XII SMA Negeri di Kabupaten Luwu Utara yang dipilih menggunakan teknik purposive sampling. Teknik pengumpulan data dengan menggunakan instrumen non tes yaitu kuesioner terstuktur dan wawancara semi terstuktur. Data penelitian dianalisis secara kuantitatif dan kualitatif. Hasil penelitian menunjukkan bahwa konsep biologi yang dipersepsikan sulit oleh siswa SMA Negeri di Kabupaten Luwu Utara berdasarkan hasil kuesioner yaitu pola-pola hereditas, sistem endokrin, transpor membran, hukum Mendel, pembelahan sel, siklus materi, klasifikasi makhluk hidup, sistem sirkulasi, sistem respirasi, virus, jaringan hewan, dan sistem saraf. Berdasarkan hasil wawancara menunjukkan bahwa konsep biologi yang dipersepsikan sulit oleh siswa yaitu perubahan lingkungan, keanekaragaman hayati, ekosistem, bioteknologi, sistem gerak, jaringan tumbuhan, sistem ekskresi, sistem pencernaan, sistem reproduksi, sistem indra, sistem imun, sintesis protein, metabolisme, dan pertumbuhan dan perkembangan. Alasan siswa mempersepsikan konsep biologi sulit disebabkan karena banyaknya istilah asing pada biologi, materi biologi yang bersifat abstrak dan kebiasaan belajar siswa yang buruk. ABSTRACT This study is a comprehensive study and uses a mixed method, especially an explanatory sequential design that aims to determine the biology concepts that are perceived as difficult by high school students in North Luwu Regency and the reasons for the concepts identified as difficult by students. This study was conducted in five high schools in North Luwu Regency, namely SMA Negeri 1, SMA Negeri 2, SMA Negeri 3, SMA Negeri 4, and SMA Negeri 19 in February 2025, the 2024/2025 academic year. The population of this study was all grade XII students of high schools in North Luwu Regency and a sample of 158 grade XII students of high schools in North Luwu Regency who were selected using a purposive sampling technique. The data collection technique used non-test instruments, namely structured questionnaires and semi-structured interviews. The research data were analyzed quantitatively and qualitatively. The results showed that the biology concepts perceived as difficult by high school students in North Luwu Regency based on the questionnaire results were heredity patterns, endocrine system, membrane transport, Mendel's laws, cell division, material cycles, classification of living things, circulatory system, respiratory system, viruses, animal tissue, and nervous system. Based on the interview results, it showed that the biology concepts perceived as difficult by students were environmental changes, biodiversity, ecosystems, biotechnology, movement systems, plant tissues, excretory systems, digestive systems, reproductive systems, sensory systems, immune systems, protein synthesis, metabolism, and growth and development. The reasons students perceive biology concepts as difficult are due to the many foreign terms in biology, abstract biology materials and poor student learning habits.

Abstract

This study aims to analyze the effect of implementing the PQ4R learning model assisted by video microlearning on students' scientific literacy and biology learning outcomes in the nervous system material. The study used a quantitative approach with a quasi-experimental nonequivalent control group design. The experimental class was taught using the PQ4R model assisted by video microlearning, while the control class used Project Based Learning (PjBL). Video microlearning was integrated in the Read and Reflect stages to help visualize abstract nervous system concepts. The study sample consisted of 36 students in the experimental class and 35 students in the control class. Data were analyzed using descriptive statistics and analysis of covariance (ANCOVA). The results showed that the average posttest of scientific literacy in the experimental class was 92.44, higher than the control class at 87.20. The average posttest of biology learning outcomes in the experimental class was 93.33, while the control class was 87.89. ANCOVA results showed that the learning model had a significant effect on scientific literacy (F = 29.282; p < 0.001; η² = 0.301) and biology learning outcomes (F = 26.082; p < 0.001; η² = 0.277) after initial abilities were controlled. The research findings showed that the PQ4R model assisted by microlearning videos was more effective than Project Based Learning (PjBL) in helping students understand the concept of the nervous system and improving scientific literacy and biology learning outcomes.
