Efektivitas Metode Eksperimen Berbantuan Media Poster Terhadap Peningkatan Hasil Belajar IPA Materi Siklus Air Kelas V Sekolah Dasar

The Effectiveness of Experimental Methods Assisted by Poster Media in Improving Science Learning Results on the Water Cycle Material for Fifth-Grade Elementary School Students

Permasalahan yang menjadi fokus utama dalam penelitian ini ialah kurangnya keaktifan serta antusiasme peserta didik pada saat mengikuti pembelajaran IPA. Hal tersebut mengakibatkan pemahaman serta hasil belajar peserta didik menjadi kurang maksimal. Penyebab dari permasalahan tersebut ialah penggunaan metode serta media yang cenderung monoton dan kurang membangkitkan aktivitas belajar peserta didik. Tujuan dari penelitian ini ialah untuk mengetahui efektivitas dan pengaruh penggunaan metode pembelajaran eksperimen berbantuan media poster terhadap peningkatan hasil belajar peserta didik kelas V sekolah dasar pada materi siklus air. Penelitian ini menggunakan metode kuantitatif dengan desain penelitian kuasi eksperimen. Pengambilan data dilakukan dengan pengisian lembar observasi keterlaksanaan pembelajaran, pretest dan posttest untuk mengukur hasil belajar peserta didik, serta angket respon peserta didik. Hasil dari penelitian ini menunjukkan bahwa keterlaksanaan pembelajaran memperoleh nilai dengan kategori sangat baik. Penggunaan metode pembelajaran eksperimen berbantuan media poster dapat dikatakan cukup efektif dengan perolehan skor N-Gain 64,38%. Hasil uji Mann Whitney yang memperoleh nilai Asymp. Sig. (2-tailed) 0,000 < 0,05 menunjukkan bahwa terdapat pengaruh yang signifikan dari penerapan metode eksperimen berbantuan media poster terhadap hasil belajar. Respon peserta didik terhadap penggunaan metode eksperimen dan media poster juga sangat baik, dimana mereka merasa senang dan lebih mudah memahami materi siklus air. Dengan demikian, dapat disimpulkan bahwa penggunaan metode eksperimen berbantuan media poster cukup efektif serta membawa pengaruh positif terhadap peningkatan hasil belajar peserta didik.

Kata Kunci: metode eksperimen, media poster, hasil belajar, siklus air.

The problem which is the main focus of this study is the lack of activeness and enthusiasm of students when participating in science learning. It makes students' understanding and learning results being less than optimal. The cause of this problem is the use of methods and media which tend to be monotonous and do not stimulate students' learning activities. The aim of this study is to determine the effectiveness and influence of using experimental learning methods assisted by poster media on improving the learning results of fifth grade elementary school students on the water cycle material. This study used quantitative methods with a quasi-experimental research design. Moreover, data collection was conducted by filling in learning implementation observation sheets, pretest and posttest in order to measure student learning results, and student response questionnaires. The results of this study show that the implementation of learning received a score in the very good category. The use of experimental learning methods assisted by poster media can be said to be quite effective with an N-Gain score of 64.38%. Furthermore, the results of the Mann Whitney test obtained the Asymp value. Sig. (2-tailed) 0.000 < 0.05 indicates that there is a significant influence from the implementation of the experimental method assisted by poster media on learning results. In addition, the students' response to the use of experimental methods and poster media is very good which can be proved that they feel happy and find it easier to understand the water cycle material. Thus, it can be concluded that the use of experimental methods assisted by poster media is quite effective; besides, it has a positive influence on improving student learning results.

Key words: experimental method, poster media, learning results, water cycle.
