AbstrakPenelitian ini bertujuan untuk menyelidiki pengaruh gender siswa terhadap literasi sains melalui pembelajaranproject based learning (PjBL) yang diintegrasikan dengan science, technology, engineering, dan mathematics (STEM) pada tema pencemaran udara. Metode penelitian yang digunakan adalah pre-eksperimen dengan desain The static Group Pretest-Posttest Designyang dilaksanakan di kelas VII SMP Islam Terpadu di kabupaten Sukabumi sebanyak 57 siswa yang terdiri dari kelas laki-laki (29 orang) dan kelas perempuan (28 orang). Pengumpulan data dilakukan dengan menggunakan tes awal dan tes akhir untuk literasi sains dan angket siswa terhadap PjBL STEM. Berdasarkan hasil analisis data diperoleh peningkatan literasi sains siswa kelompok laki-laki dan kelompok perempuan sama-sama mengalami peningkatan dengan rerata N_Gainyaitu 0,36 dan 0,31pada kategori sedang untuk aspek pengetahuan dan kompetensi. Hasil uji-t menunjukkan bahwa peningkatan literasi sainskelas laki-laki dan kelas perempuan berbeda tidak signifikan.Pada aspek sikap sains, kelas perempuan berbeda signifikan dari kelas laki-laki.Tanggapan siswa secara keseluruhan menunjukkan hampir seluruh siswa menyatakan senang dengan pembelajaran PjBL STEM dan memperoleh pengalaman yang sangat berkesan mengikuti tahapan pembelajaran sehingga menimbulkan motivasi dan minat dalam belajar.
This study aims to develop of multimedia based on science literacy on the lightning themes and apply it on the science learning to improve of students' scientific literacy. The method used in this research is Research and Development with ADDIE (Analysis, Design, Development, Implementation and Evaluation) models. The research design at the multimedia implementation as small scale on the science learning by using one-group pretest-posttest design. Implementation was carried out in class IX with 31 students with cluster random sampling. The result of research showed: (1) multimedia based on science literacy on lightning themes in the form of text, images, animation, and videos that refer to the 2015 PISA framework are content, science competencies and science attitudes domains; (2) the feasibility test by the expert and teacher show all aspects of multimedia have a very good category, it is suitable for use in science learning; and (3) the using of multimedia can increase science literacy skills especially content and scientific attitude domains have medium category. As well as competency domains show is very good categories. This is supported by respon of student that multimedia is very good in the domain aspects of literacy and motivation, whereas in aspect of operating multimedia have good categories.
Untuk meningkatkan literasi sains siswa, diperlukan inovasi-inovasi khususnya pada pembelajaran IPA.Salah satu inovasi yang dapat dilakukan adalah pengembangan bahan ajar. Dalam penelitian ini bahan ajar dikembangkan melalui proses rekonstruksi, dimana struktur konten untuk pengajaran dibangun dengan memperhatikan tujuan pendidikan serta diuraikan secara hati-hati dan dihubungkan dengan konteks dalam kehidupan nyata. Salah satu materi konten sains yang sangat dekat dengan konteks dalam kehidupan nyata adalah materi zat aditif makanan. Penggunaan zat aditif yang tidak sewajarnya muncul sebagai Socio-Scientific Issues (SSI) kontroversial yang ramai dibicarakan. Penggunaan SSI sebagai konteks diharapkan dapat dijadikan penghubung permasalahan nyata di masyarakat. Penelitian ini dilakukan dengan metode R&D dan desainnya adalah Model of Educational Reconstruction yang dimodifikasi.Bahan ajar dengan konteks SSI pada materi zat aditif makanan yang telah dikembangkan terdiri dari delapan sub bab. Setiap sub bab memuat deskripsi materi, daftar bacaan tambahan dan soal latihan. Penilaian bahan ajar dilakukan dengan 2 cara, yaitu validasi berdasarkan kriteria umum dan penilaian berdasarkan kriteria Badan Standar Nasional Pendidikan (BSNP). Hasil penilaian menunjukkan bahan ajar sudah layak dan memenuhi syarat untuk digunakan dalam proses pembelajaran IPA di kelas VIII SMP. Hasil implementasi menunjukkan bahwa bahan ajar memiliki pengaruh yang besar dan dapat meningkatkan literasi sains siswa baik pada aspek kompetensi maupun sikap.Tanggapan siswa menunjukkan bahwa bahan ajar dengan konteks SSI pada materi zat aditif makanan sudah dipahami dan memenuhi harapan belajar siswa.Kata kunci: bahan ajar,model of educational reconstruction, socio-scientific issues (SSI), zat aditif makanan, literasi sains Reconstruction of Learning Materials with Socio-Scientific Issues Context on Food Additives Content to Improving Student’s Scientific Literacy AbstractTo improved scientific literacy of Indonesian students, needed innovations especially for science education. One of innovation that can be done is the development of learning materials. In this research, learning materials were developed through reconstruction process,structure of content for learning was built with attention educational aims, described carefully and linked to context in the real life. One of science content that very close with context in the real life is food additives. The use of food additives were not reasonably emerged as controversial socio-scientific issues (SSI) that lively discussed. The use of SSI as context in learning materials expected to be used as link real problem in society. This research was conducted with R&D method and the design is model of educational recontruction modified. Learning materials with SSI context on food additives content has been developed consist of eight sub chapter. Each sub chapter contains material description, extra reading list and prctices. Assessment of learning materials is done in two ways, validation based on the general criterias and assessment based on Badan Standar Nasional Pendidikan (BSNP) criterias. The resultindicated the learning materials already worthy and qualified for use in science learning process in 8th junior high school. The implementation result shows that learning materials have great influence and improve student’s scientific literacy at both competencies and attitude aspects. The student’s response suggest that learning materials with SSI context on food additives content already understood and fulfilled students learning expectation.Keywords: learning materials, model of educational reconstruction, socio-scientific issues (SSI), food additives, scientific literacy
Penelitian ini bertujuan untuk mengetahui efektivitas virtual lab berbasis STEM sebagai media praktikum alternatif dalam meningkatkan literasi sains siswa dengan perbedaan gender. Penelitian ini menggunakan desain one Group pretest-posttest yang terdiri dari kelas 7B dengan jumlah siswa 29 orang perempuan dan kelas 7D dengan jumlah siswa 30 orang laki-laki. Teknik pengambilan data menggunakan metode observasi, angket, dan tes. Efektivitas virtual lab berbasis STEM dianalisis dengan Independent-samples t test kemudian dihitung nilai effect size. Hasil penelitian menunjukkan bahwa terdapat perbedaan hasil peningkatan literasi sains siswa kelas perempuan (7B) sebesar 0,46 dan kelas laki-laki (7D) sebesar 0,29 dengan keduanya dalam kategori sedang. Nilai effect size penggunaan virtual lab berbasis STEM pada domain konten dan kompetensi sains sebesar 0,39 dengan kategori sedang dan domain sikap sebesar 0,75 dengan kategori tinggi Kata kunci: virtual lab, STEM, literasi sains, gender Stem-Based Virtual Lab Effectiveness in Improving the Scientific Literacy of Students with Gender Differences AbstractThis study aimed to know theeffectiveness of STEM-based virtual lab in improving the scientific literacy of students by gender differences.The design of this research one group pretest-posttest consisting of class 7B by the number of students 29 women and 7D class by the number of students 30 men.The data Ade collected through questionnaires, observations, and tests. The effectiveness of STEM-based virtual lab was analyzed through Independent-samples t test then calculated the value of effect size. the results showed that there are differences the resulting increase inscientific literacy class students women (7B) of 0.46 and a class of men (7D) of 0.29 with both of them in the medium category.The value of effect size using STEM-based virtual lab on the science content domain and competencies of 0.39 with the moderate category and attitude domain of 0.75 to a high category.Keywords: virtual lab, STEM, Scientific literacy, gender
