Penerapan blended learning dengan pendekatan STEM untuk meningkatkan kemampuan literasi sains siswa pada pembelajaran biologi di masa pandemi covid-19

Penelitian ini bertujuan untuk memperoleh informasi tentang bagaimana penerapan model blended learning dengan pendekatan STEM terhadap keterampilan literasi sains siswa pada konsep cendawan pada saat pandemi COVID. Metode penelitian yang digunakan adalah pre-eksperimen dengan one group pretest-posttest design. Penelitian ini dilaksanakan di SMAN 1 Bojong Gede Kabupaten Bogor pada tahun ajaran 2020/2021. Sampel menggunakan dua kelas X yang dipilih secara purposive sampling. Instrumen penelitian ini adalah tes literasi sains siswa yang berisi 20 butir soal. Teknik pengolahan data dilakukan secara deskriptif, kemudian data dianalisis secara inferensial dengan tes wilcoxon. Hasil penelitian menunjukkan bahwa secara umum rata-rata kemampuan literasi sains siswa dari penerapan model blended learning dengan pendekatan STEM memiliki skor rata-rata 85,50 dengan kategori baik. Agar siswa memiliki pemahaman literasi sains yang lebih baik, pemahaman siswa terhadap sains harus terus dilatih melalui model blended learning dengan pendekatan STEM.

Penelitian bertujuan untuk mengetahui pengembangan lembar kerja peserta didik berbasis multimedia interaktif pada materi kingdom monera Bentuk penelitian adalah research and development dengan prosedur yang mengacu pada model ADDIE yang meliputi tahap analyze, design, develop, implement dan evaluate. Penelitian ini dilakukan di 2 sekolah yaitu, MAN 2 Pontianak dan SMA Muhammadiyah 1 Pontianak dengan subjek penelitian sebanyak 12 orang peserta didik pada uji skala kecil dan 30 orang peserta didik pada uji skala besar. Instrumen yang digunakan adalah lembar validasi LKPD berbasis multimedia interaktif dan angket respons peserta didik. Hasil validasi LKPD berbasis multimedia interaktif materi kingdom monera adalah 0,98 sehingga dinyatakan valid. Hasil respons pada uji skala kecil (77,28%) dengan kategori kuat. Sementara pada uji skala besar (81,17%) dengan kategori sangat kuat. Berdasarkan hasil tersebut dapat disimpulkan bahwa LKPD berbasis multimedia interaktif layak digunakan sebagai bahan ajar pada materi kingdom monera dan mendapat respons dengan kategori sangat kuat.

Peningkatan Aktivitas dan Hasil Belajar Materi Sistem Ekskresi Melalui Inkuiri Terbimbing Pada Siswa SMP Negeri 1 Kemalang

This study aimed to improve the learning outcomes of class VIII E students of SMP Negeri 1 Kemalang in the 2018 2019 academic year using the Guided Inquiry learning model. This research was a class action research consisting of 2 cycles. Each cycle consists of planning. observation and reflection. Data were taken from students who were the subject of research. The technique of collecting data using observations, written tests and documentation. The data analysis technique used comparative descriptive. The results showed that study stated at the first cycle of student activity were 67% and learning completeness was 73%. In cycle II, student activity was 80 %. Already met the performance indicators ≥75% of students achieved high activity criteria (≥ 75%). Classical completeness increased by 87%, it has met the performance indicator, namely ≥ 85%. So it can be concluded that the guided inquiry learning model can improve student learning outcomes. Keywords: learning activities, learning outcomes, guided inquiry

Keanekaragaman dan Kemelimpahan Tumbuhan Paku di Cagar Alam Donoloyo sebagai Bahan Pengembangan Multimedia Interaktif Biologi di SMA

This study aims 1) to determine the index of species abundance, characteristics, morphology of ferns in the nature reservearea of Donoloyo, Watusomo, slogohimo 2) to obtain an alternative source of learning biology in high school about the abundance of ferns based on interactive multimedia in the form CD 3) to find out the multimedia validation of interactive learning biology of ferns. This research method is descriptive quantitative exploration, the instrument used is a direct observation technique with the quadrat method and validation sheet. The results of the study showed that in the Donoloyo nature reserve, 12 species of ferns were found in 2 classes and 5 families which showed in the medium category. Observations of ferns are used as learning resources in the form of interactive multimedia learning. The quality of interactive media assessed by 3 validators namely material experts, media experts, and biology teacher get a percentage >80% (very valid) interactive multimedia is ready to be used as a learning media for biology in high school.

Identifikasi Vertebrata Kelas Mamalia di Taman Satwa Taru Jurug Surakarta Sebagai Bahan Materi Pengembangan Video Pembelajaran Biologi SMA Kelas X

The purpose of this study was to identify Vertebrate animals of the Mammal class, order artiodactyla, family Cervidae in the Jurug Surakarta taru Animal Park, develop interactive video media as a result of identification of vetebrata animals into learning media, know the quality of interactive video media based on assessment by material experts, media experts and biology teachers, and applications in learning. The research method uses an observation method by making direct observations of vertebrate species. The instrument for assessing the quality of interactive video media is based on material aspects and presentation aspects, with a qualitative descriptive analysis design. The results of this study indicate that in Taru Jurug Animal Park Surakarta there are 3 species of animals namely Cervus unicolor, Cervus timorensis, Axis-axis and all three have been identified. Research on the identification of vertebrate animals, especially the mammalian class, order artiodactyla, and the cervidae family can be used for the preparation of interactive video media with material on Biodiversity at the level of genes and species. The quality of interactive video media in terms of material aspects, presentation, and language. Assessment of material experts obtained a percentage of 90.9% so that it was categorized as very valid, media experts obtained a percentage of 88.5% so it was categorized as very valid, biology teacher Veteran 1 Sukoharjo High School obtained a percentage of 92.5% so it was categorized as very valid and biology teacher Nguter 1 Public High School obtained a percentage of 97.5% so it is categorized as very valid. Based on this, it can be concluded that this interactive video media is worthy of being used by teachers as one of the learning media about Biodiversity at the level of genes and species.
