Penelitian ini mendukung untuk meningkatkan kembali yang dapat meningkatkan prestasi siswa. Pada penelitian ini dilaksanakan pada bulan Maret 2020 hingga 1 April 2020. Penelitian ini menggunakan desain meta analisi. Dalam penelitian ini, pengumpulan data diperoleh dari artikel-artikel di jurnal online. Kriteria artikel yang dipilih adalah tentang keberadaanasan tentang Gadget dan Prestasi Siswa, selain itu ada skor yang diperoleh dari penggunaan gadget terhadap prestasi siswa. Dari 10 artikel yang diperoleh, kemudian dipilih yang paling relevan dan diperoleh 6 artikel yang dipilih. Hasil dalam penelitian, yang menunjukkan cara menggunakan gadget yang dapat dibandingkan dengan prestasi siswa.Hal ini dapat dilihat dari nilai presentase yang terendah yaitu 5,5% dan yang tertinggi 97,7%. Dan ditemukan nilai rata-rata sebesar 56%.
This study aimed to determine the improvement in writing skills of science teaching materials for elementary school teachers students through the Project-Based Learning (PjBL) model. This study used a quasi-experimental method with One Group Pretest-Posttest Design using portfolio assessment sheets to write science teaching materials. Data were analyzed using a T-test. This study's subjects were pre-service teacher students who contracted Natural Science Learning courses in the Elementary Teacher Education Program. The study results indicated that PjBL could increase pre-service teachers' skills in developing teaching materials relevant to the 21st-century skills, students' character, and the applicable curriculum. This result is evidenced by the results of the assessment, which increased significantly from 2.04 to 3.25. It is also based on the Wilcoxon test that Asymp.Sig. (2-tailed) 0.05 which is 0.000. It means that there is an influence in the form of an increase in the PjBL model's use of the writing skills of science teaching materials for elementary teacher students. This study recommends that the PjBL model can be used as an alternative learning model to improve the writing skills of teaching materials for students.
This study aimed to determine the difference in students' scientific literacy skills between students who apply the PjBL model integrated STEM-assisted science literacy modules and students who apply lecture learning accompanied by experiments. The subjects of this study were 60 Elementary Teacher Education students who were divided into two classes at IKIP Siliwangi Bandung. This study used a comparative research method with a quantitative approach. The data collection method used was the scientific literacy skills test method. The test instrument in this study measured three scientific literacy competencies, namely the ability to explain scientific phenomena, evaluate and design scientific investigations, and interpret scientific data and evidence. The data were analyzed using descriptive analysis techniques and an Independent Sample T-Test. This study's results showed that the average scientific literacy ability of students who received the STEM-integrated PjBL model in this study was 83. The T-test of average students' scientific literacy ability showed that the PjBL model integrated STEM-assisted modules affected students' scientific literacy skills better than lecture learning accompanied by experiments. The recommendation of this study is further research to modify the STEM-integrated PjBL model assisted by this module to be more effective in improving students' ability to interpret scientific data and evidence.
Tujuan dari penelitian ini adalah untuk melakukan validasi secara konstruk dan isi pada multimedia interaktif materi kemagnetan berbasis indikator penguasaan konsep dan kemampuan berpikir kreatif. Jenis penelitian ini termasuk penelitian dan pengembangan (Research and Development). Pengembangan ini menggunakan metode pengembangan 4D yaitu define, design, develop, dan dissemination.Multimedia interaktif pada materi kemagnetan berbasis indikator penguasaan konsep dan kemampuan berpikir kreatif yang dikembangkan terdiri dari aplikasi multimedia interaktif dengan Macromedia Flash 8, Lembar Kerja Peserta Didik (LKPD), RPP, dan instrumen evaluasi. Jurnal ini hanya fokus pada validitas produk yang dikembangkan. Uji validasi dilakukan oleh 4 orang validator ahli dibidang fisika dan pendidikan. Berdasarkan hasil analisis validasi menggunakan indeks Aiken dan analisis reliabilitas menggunakan percentage agreement diperoleh bahwa validitas multimedia interaktif pada materi kemagnetan berbasis indikator penguasaan konsep dan kemampuan berpikir kreatif yang dikembangkan memiliki kriteria valid dan reliabel.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
