This research aims to develop open ended-based worksheet in improving students' high-level thinking skills on static fluid materials. The method used in this research is Research and Development (R&D) with 3 steps namely, the initial stage, then the design and development of the product, and finally the product testing. The data analysis technique for product effectiveness is with the main field trials, namely (1) N-gain analysis, (2) paired t-test, (3) ANCOVA, and finally (4) effect size test. From the test results obtained information that conducted 10 students showed the results of the development worksheets obtained the average worth of development products by 90% this value is included in the very high category, while the student response of the average of 88% and also the readability response of 89% in the very high category. In the results of the n-gain analysis also show the value is0.70, that mean medium category. From the results of this study, it can be concluded that worksheets based on open ended can improve students' higher-order thinking skills. So, in further development we suggest that open ended-based on worksheet is not only applied to static fluid material, but also in other materials.
Literasi numerasi sains merupakan pengetahuan dan kecakapan untuk menggunakan berbagai macam bilangan dan simbol yang terkait dengan matematika dasar untuk memecahkan masalah praktis dalam berbagai konteks kehidupan sehari-hari. Literasi numerasi juga mencakup pengetahuan dan kecakapan menganalisis informasi sains yang ditampilkan di dalam berbagai bentuk (grafik, tabel, bagan, dan lain sebagainya) lalu menggunakan interpretasi hasil analisis tersebut untuk memprediksi dan mengambil kesimpulan dan keputusan. Penelitian ini bertujuan untuk mengetahui efektifitas pembelajaran menggunakan Google Classroom (GCR) berbantuan WhatsApp (WA) terhadap kemampuan literasi numerasi sains siswa materi Kalor. Penelitian ini adalah penelitian pengembangan dengan model ADDIE dengan jenis desain penelitian pretest-posttest one group design yang melibatkan 2 kelas siswa kelas VII yang terdiri dari 50 siswa di salah satu SMP di Kota Bandar Lampung. Instrumen penelitian berupa soal tes literasi numerasi sains materi Kalor. Analisis data menggunakan uji n-gain. Hasil tes literasi numerasi sains menunjukkan bahwa pembelajaran menggunakan Google Classroom berbantuan WhatsApp memperoleh nilai n-gain pada kelas eksperimen sebesar 0,66 dan 0,57 (kategori sedang). Hasil ini menunjukkan bahwa Teknik pembelajaran menggunakan Google Classroom berbantuan WhatApps efektif digunakan dalam pembelajaran online pada masa pandemi Covid 19.
This study examines the use of e-worksheets and PHET Simulation as virtual laboratories in science. This study aims to determine whether the use of PHET Simulation with e-worksheet guidance can optimize online learning to minimize learning loss due to the Covid 19 pandemic. E-worksheets are used as scaffolding media that are used to help guide students to do online practicums. The research was conducted in two stages. The first stage is conducting a direct trial of learning using PHET Simulation and e-worksheets through Google Classroom. For the second stage, the activities include collecting data using an accessibility questionnaire using a google form. The data were then analyzed by usability test covering aspects of usefulness, ease of use, ease of learning, and satisfaction. The usability test results show that the percentage of respondents to the questions given is dominated by the Agree (S) and Strongly Agree (SS) statements on all usability test indicators. This shows that the use of e-worksheets and PHET Simulation as a virtual laboratory fulfils the element of usability.
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.
