ABSTRAKPendidikan abad 21 membutuhkan keterampilan berpikir yang meliputi keterampilan berpikir logis, analisis, kritis, dan kreatif. STEM (Science, Technology, Engineering, and Mathematics) merupakan isu penting dalam pendidikan di Indonesia saat ini. Penerapan STEM dalam pembelajaran dapat mendorong peserta didik untuk mendesain, mengembangkan dan memanfaatkan teknologi, mengasah kognitif, manipulatif dan afektif, serta mengaplikasikan pengetahuan (Kapila & Iskander, 2014). Tujuan dari penelitian ini untuk mengetahui implementasi pendekatan STEM (manfaat dan tantangan) di Indonesia dengan menggunakan metode Systematic Literatur Review. Jumlah artikel yang ditemukan sebanyak 56 artikel yang dianggap sesuai dengan tujuan penelitian kemudian dijadikan satu lalu dilakukan screening apakah judul pada artikel tersebut ada yang sama atau tidak. Setelah dilakukan screening didapatkan ada 30 artikel yang judulnya sama, dari 30 artikel ini kemudian di screening berdasarkan eligibility sesuai dengan kriteria inklusi dan ekslusi didapatkan 25 artikel untuk selanjutnya dilakukan review. Pada sistematic review ini menunjukkan bahwa implementasi pendekatan STEM di Indonesia memiliki pengaruh yang cukup baik terhadap terhadap cara berpikir kreatif siswa, LKS, buku siswa dan menghadapi revolusi industri 4.0 ,literasi matematis dan implementasi STEM dengan robotika, dan juga persepsi guru terhadap pembelajaran STEM.KataKunci: Implementasi,Systematic Literatur Review,STEM
The purpose and problem formulation of this research is to find out whether realistic mathematics learning assisted by google classroom can improve students' communication skills and independence. This research method is descriptive quantitative research. This research was conducted at SMP Negeri 1 Pangkat in February-March 2021 in the even semester of the 2020/2021 learning year. The sample in this study were 25 students who were taken from the total population of data and could represent the entire population with the sample collection technique, namely the random sampling technique. The instruments used were tests and questionnaires with the data analysis technique using multiple regression tests. The results of this study were tested with multiple correlation test which resulted in a significant value of 0.011 < 0.05 and F counting 5.663 > F table 3.42. With an increase in communication skills and student independence simultaneously (simultaneously) to variable Y is 34%. So it can be concluded that there is an increase in students' communication skills and independence through realistic mathematics learning (PMR) assisted by google classroom.
This study aims to determine the growth phase of Skeletonema costatum with different concentrations of Guillard fertilizer and to determine the effect of Guillard fertilizer concentration on the quality of the growth medium for Skeletonema costatum. This study used an experimental research method with 4 stages of research, namely preparation of Guillard fertilizer, preparation of aqueous media, preparation of Skeletonema costatum culture and observation of the growth phase. Data from testing the parameters for measuring water quality were analyzed descriptively. The design used in this study was RAL with 4 treatments, namely without guillard fertilizer (NP0), BPBAP dose of guillard fertilizer (NP1), increased dose of guillard fertilizer (NP2), and reduced dose of guillard fertilizer (NP3) with 4 repetitions. test. The results showed that the doses of NP0, NP2 and NP3 had less optimal growth compared to the NP1 dose where the density was optimal according to SNI 4958:2015. The average pH quality is 7-9, the average DO quality is 3-7, the average salinity quality is 29-35 ppt, the average temperature quality is 20-30ºC and the average light quality is 500-1200 lux.Keywords: Skeletonema costatum, Guillard, Growth, Water Quality Parameters
Penelitian tindakan kelas ini bertujuan untuk meningkatkan kemampuan kognitif melalui kegiatan mencampur warna menggunakan media pewrana. Subjek dalam penelitian tindakan kelas ini adalah anak taman kanak – kanat kelompk B.1 yang berjumlah 15 orang terdiri dari 9 anak perempuan dan 6 anak laki-laki. Tehnik pengumpulan data adalah dengan menggunakan data kuantitatif berupa tes dan data kualitatif berupa observasi. Hasil observasi menunjukan bahwa siklus I guru (peneliti) sudah dapat meningkatkan kemampuan kognitif anak dengan capaian (43%) dan pada siklus II kemapuan kognitif dapat meningkat dengan sangat baik (88%).
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.
