Selama pandemi COVID-19, sistem pembelajaran daring menjadi hal yang umum dilakukan. Untuk membuat siswa tertarik mengikuti pembelajaran, diperlukan media pembelajaran yang mudah digunakan dan interaktif. Media powerpoint interaktif diusulkan karena powerpoint merupakan media yang umum digunakan, mudah dibuat guru, dan digunakan siswa untuk mendalami materi. Tujuan penelitian untuk mengetahui keefektifan metode powerpoint interaktif terhadap peningkatan hasil pembelajaran Matematika siswa kelas observasi, yaitu kelas VIII-C SMPN 1 Mojo Kabupaten Kediri tahun pelajaran 2020/2021. Materi yang digunakan dalam penelitian adalah kompetensi dasar barisan bilangan kelas VIII. Hasil penelitian menunjukkan bahwa, pembelajaran daring menggunakanpowerpoint interaktif pada siswa dapat meningkatkan hasil pembelajaran Matematika. Hal ini terlihat berdasarkan kenaikan siswa yang tuntas belajar di setiap siklus tahapannya. Berdasarkan siklus tahapan penelitian, diperoleh hasil kenaikan persentase ketuntasan belajar berturut-turut, yaitu a) 65,21% pada siklus I, b) 78,26% pada siklus II, dan c) 90,9% pada siklus III. Selain itu diperoleh peningkatan poin aktivitas siswa, masingmasing a) 6,06 pada siklus I, b) 8,53 pada siklus II, dan c) 11,15 pada siklus III. Kenaikan pesentase ketuntasan dan peningkatan poin aktivitas siswa signifikan berdasarkan hasil uji hipotesis-t multilevel. Dengan demikian, media powerpoint interaktif dapat diterapkan untuk meningkatkan persentase ketuntasan belajar berdasarkan hasil evaluasi. Kata kunci: hasil evaluasi, pandemi COVID-19, pembelajaran daring, powerpoint interaktif.
One of the biggest problems in the continuity of one’s education is the education fee which is often unaffordable. Therefore, the existence of education insurance is a solution to this problem. Along with increasing public interest in education insurance, insurance companies need to adjust the claims reserves with the number of claims paid to maintain the company’s capital. Claim reserves are funds that must be provided by insurance companies to fulfil obligations to policy holders in the future. Losses and inaccuracies in the payment of insurance claims will result in the policy holder and the insurance company itself. Therefore, it is necessary to do a prediction of insurance company’s monthly reserve claims. In education insurance, the claim reserve data has seasonal characteristics and the number of educational insurance claims tends to increase at the turn of the school year. These fluctuating patterns are supposed to fit the application of the SARIMA model and the nonparametric regression model with the Fourier series estimator in forecasting. Fourier series is a function that has flexibility in approaching fluctuating, seasonal, and recurring data patterns. The results showed that the prediction accuracy of the SARIMAX model was higher than the nonparametric regression model with MAPE of 15% and 4% respectively.
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.
