Penelitian ini bertujuan untuk mengembangkan modul elektronik (E-Modul) berbasis project based learning terintegrasi media komputasi hyperchem pada materi bentuk molekul. Pengembangan e-modul sebagai implementasi teknologi, informasi dan komunikasi dalam media pembelajaran di Universitas Negeri Medan. E-modul disusun sesuai kurikulum Kerangka Kualifikasi Nasional Indonesia (KKNI) untuk meningkatkan hasil belajar mahasiswa. Penelitian ini termasuk penelitian pengembangan (research and development) dengan model pengembangan Analysis-Design-Development-Implementation-Evaluation (ADDIE). Instrumen yang digunakan pada penelitian adalah lembar uji kelayakan e-modul berdasarkan BSNP dan tes hasil belajar mahasiswa untuk uji coba penggunaan e-modul. E-modul dianalisis menggunakan uji Independent Sample T-test pada program SPSS 21.0 for windows. E-modul yang dikembangkan telah divalidasi menggunakan skala likert pada aspek kelayakan isi, kelayakan bahasa, kelayakan penyajian dan kelayakan kegrafikan. Hasil validasi terhadap e-modul diperoleh nilai rata-rata keseluruhan dari keempat aspek sebesar 3,64 yang dinyatakan sangat layak untuk digunakan mahasiswa dalam pembelajaran. Berdasarkan hasil uji coba penggunaan e-modul diperoleh n-gain pretest dan posttest hasil belajar mahasiswa sebesar 0,78 yang tergolong kategori tinggi.
The research aims to determine the effect of learning style on students’ performance through online learning during the Covid-19 pandemic. The subjects of study are 269 chemistry education students at three universities in Indonesia. The data collection of learning style uses a Likert scale questionnaire, and learning performance is obtained from students’ grade point average. In this research, students’ learning style was divided into visual, auditorial, and kinesthetic. Data were analyzed using descriptive statistics with linear regression and ANOVA tests. The learning styles positively affect student learning performance by 4.7%, while 95.3% of other factors are not examined in this study. The learning performance of students with auditory is higher than visual and kinesthetic learning styles. Based on the inferential analysis, there is no significant difference in student learning performance based on student learning styles. Therefore, students with different learning styles have the same learning performance in online learning.
This study aims to determine: (1) the feasibility of interactive learning media based on Adobe Flash CS6; (2) differences in motivation and learning outcomes using interactive learning media based on Adobe Flash CS6 and using chemistry learning media on the internet; (3) the influence of motivation on learning outcomes. This study uses R&D ADDIE (Analysis, Design, Development, Implementation, and Evaluation) method. The population was all students of second grade at SMA Negeri 1 Padangsidimpuan. The samples were taken by using purposive sampling, there were 60 students from two classes at the second grade. The data collection instruments were tests and questionnaires. The results: (1) the feasibility of interactive learning media based on Adobe Flash CS6 shows the mean is 4.5, which is very suitable to use; (2) motivation and learning outcomes using interactive learning media based on Adobe Flash CS6 shows 94.7% and 87.17 which is higher than the motivation and learning outcomes using chemistry learning media on the internet, namely 88.5% and 79.67; (3) the effect of learning motivation in learning outcomes using interactive learning media based on Adobe Flash CS6 is 18.6%. The results of this study is used as an input for teachers and prospective teachers in using interactive learning media to create fun learning and increase motivation that will have an impact on learning outcomes.
Penelitian ini mengkaji mengenai pengetahuan masyarakat Desa Manggul-Lahat Sumatera Selatan tentang pembuatan bekasam dan membandingkan atau mengkorelasikan dengan konsep ilmiah. Penelitian ini menggunakan metode penelitian kualitatif deksriftif dengan pendekatan etnosains. Adapun Langkah-langkah yang diambil dalam pegumpulan data yaitu wawancara, observasi, dokumentasi dan studi literatur. Hasil penelitian ini menunjukkan bahwa bekasam merupakan makanan khas masyarakat di Indonesia terutama masyarakat Sumatera Selatan, Kalimantan dan Jawa Tengah yang pengetahuan pengelolaannya diwariskan secara turun temurun. Selanjutnya dalam proses pembuatan terdapat hubungan kajian ilmiah antara budaya dan ilmu sains. Dengan demikian proses pembuatan bekasam dapat menjadi bahan pembelajran IPA. Oleh karena itu, peran guru sangat penting agar tersampaikan nilai-nilai kearifan lokal dengan ilmu sains.
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.
