Efektivitas Penerapan Model Discovery Learning Terhadap Hasil Belajar IPA

Abstract

Abstrak: Penelitian ini bertujuan untuk mengetahui efektivitas penerapan model discovery learning terhadap hasil belajar IPA peserta didik di kelas VII SMP Negeri 14 Mataram semester genap tahun ajaran 2018/2019. Jenis penelitian ini adalah kuantitatif bersifat eksperimen semu (quasi experimental) dengan desain yaitu Nonequivalent Control Group Design. Populasi dalam penelitian ini yakni seluruh kelas VII di SMP Negeri 14 Mataram yang terdiri dari 8 kelas dan berjumlah 255 orang. Penentuan sampel penelitian menggunakan teknik cluster sampling sehingga terpilihlah 2 kelas. Penentuan kelas eksperimen dan kelas kontrol menggunakan undian sehingga terpilih kelas VII B sebagai kelas kontrol dan kelas VII A sebagai kelas eksperimen. Instrumen yang digunakan dalam penelitian adalah tes hasil belajar ranah kognitif dan dianalisis menggunakan analisis kovarian (ANAKOVA). Nilai signifikansi pada nilai posttest terkoreksi nilai pretest adalah 0,000 < 0,05. Hal ini menunjukkan bahwa nilai pretest peserta didik dan model pembelajaran yang digunakan dapat mempengaruhi nilai posttest yang diperoleh peserta didik. Berdasarkan NGain-score yang diperoleh, nilai rata-rata pada kelas eksperimen yaitu 0,4747. Sedangkan nilai rata-rata pada kelas kontrol yaitu 0,3747. Terdapat peningkatan hasil belajar yang lebih baik pada kelas eksperimen yang menggunakan model pembelajaran discovery learning dibandingkan dengan kelas yang menggunakan metode konvensional. Kesimpulan hasil penelitian menunjukkan bahwa penerapan model discovery learning efektif terhadap hasil belajar IPA peserta didik di kelas VII SMP Negeri 14 Mataram semester genap tahun ajaran 2018/2019. Abstract:The purpose of this study was to determine the effectiveness of discovery learning model application towards the science learning outcomes of students in VII grade of SMP Negeri 14 Mataram even semester of 2018/2019 academic year. The type of this study was quasi-experimental with the design was Nonequivalent Control Group Design. The populations in this study were all classes in VII grade of SMP Negeri 14 Mataram which consisted of 8 classes and the number of students was 255 people. The determination sample of this study was using cluster sampling techniques so that 2 classes were chosen. The determination of the experimental class and control class used a lottery so that class VII B was chosen as a control class and class VII A as an experimental class. The instrument that used in this study was a cognitive learning outcomes test and the test was analyzed using analysis of covariance (ANAKOVA). The significance value in the posttest which was corrected by pretest value was 0,000 <0.05. The data showed that the pretest scores of students and the learning model which was used can influence the obtained posttest scores of students. Based on the NGain score, the average of experimental class was 0.4747. Meanwhile, the average of the control class was 0.3747. There was an enhancement in learning outcomes that were better in the experimental class which was using the discovery...

Application of Discovery Learning Model in Increasing Student Interest and Learning Outcomes

“…It is influenced by the lack of practicum activities to prove the gap between theory and practice. This is in accordance with the opinions expressed by Nurfathoanah (2017); Charli et al (2018); Priliza et al (2020) that the characteristics of physics have abstract object studies, and many assume that physics is difficult, filled with numbers and formulas accompanied by a monotonous and less interesting learning atmosphere so that students are afraid, lazy less interested in learning it and some learners are less active during learning activities. As a result, students' learning outcomes are unable to meet desired competencies.…”

Developing online learning video based on the science technology society (STS) to improve biology learning outcomes

“…This is in line with the opinion of Majas [16] that the application of the STS approach is very effective in improving science process skills and activeness in learning. In this approach, the teacher as a learning facilitator makes efforts to overcome learning problems in the classroom so that students are actively involved so that they can have a positive influence on their learning outcomes [17]. Showing a video that lasts approximately 10 minutes and the application of the STS approach is able to direct students effectively in achieving learning objectives.…”

Pengembangan Media Pembelajaran IPA dengan Menggunakan Media “Rumah Eksis” di Sekolah Dasar

“…(Khoiriyah & Sari, 2018) adapun pendapat Djumhana dalam jurnal priliza yang mengemukakan bahwa IPA adalah ilmu yang berhubungan tentang gejala-gejala alam yang disusun secara sistematis dan teratur, berlaku secara umum berupa hasil observasi serta eksperimen. (Prilliza et al, 2020) Putra dalam veronica berpendapat bahwa Pembelajaran IPA di sekolah dasar sebaiknya memberikan kebebasan para peserta didik dalam membuat suatu ide ataupun sebuah penafsiran pada suatu hal dalam sebuah kegiatan pembelajaran untuk merancang serta menemukan sesuatu secara mandiri. (Veronica et al, 2018) adapun menurut susanto dalam widiana yang berpendapat bahwa IPA merupakan sebuah usaha manusia dalam memahami serta mempelajari ilmu alam semesta melalui sebuah pengamatan yang tepat terhadap sasaran serta menggunakan berbagai prosedur yang dijelaskan juga dengan suatu penalaran maupun pemahaman sehingga mendapatkan hasil atau sebuah kesimpulan.…”
