Abstract

This research aims to find out whether the group learning model is implemented Investigation is effective in improving the science process skills of students at SMP Negeri 17 South Halmahera. The type of research is quantitative with experimental methods, one-group pre test post test design research design. The sample in this research was 28 class VIII students of SMP Negeri 17 South Halmahera, obtained using the Simple Random Side technique and seen from the table determining the number of samples from a certain population, with an error rate of 5%. The data obtained from the research sample was in the form of students' science process skill scores regarding growth and development in living things. Data analysis was carried out using paired sample t-test. The results of research data analysis show that the application of the Group Investigation learning model is effective on the science process skills of students at SMP Negeri 17 South Halmahera. This is proven by the average results of the analysis of science process skills obtained from observation sheets of 81.96 and the average results of post-test data analysis of 82.35. Proven by hypothesis testing using paired sample t-test sig value. (2-tailed) is 0.000 < 0.05, so H0 is rejected and H1 is accepted.

Abstract

Pendidikan dipercaya sebagai usaha yang sengaja dan terencana untuk membantu perkembangan potensi dan kemampuan anak agar bermanfaat bagi kepentingan hidupnya. Dengan pendidikan maka sebagai seorang individu yang tidak berdaya pada saat permulaan kehidupan mampu menjadi suatu pribadi yang berdiri sendiri (mandiri) dan sebagai warga Negara atau masyarakat. Dengan kata lain, pendidikan dipandang mempunyai peranan yang besar dalam mencapai kebehasilan dalam perkembangan anak.Jika hal ini dibiarkan maka siswa akan mengalami kesulitan dalam memahami materi dan motivasi dalam diri siswa untuk belajar lambat laun akan menurun. Dari pendapat di atas menunjukkan bahwa media gambar memiliki peran yang sangat penting dalam proses belajar mengajar, salah satu media gambar yang sangat cocok dengan karakter siswa khususnya siswa kelas IV yaitu model STAD hal ini karena siswa pada tahap ini masih dalam tahap operasional kongrit dimana siswa belum bisa memberikan penalaran yang luas terhadap materi IPA. Penelitian ini termasuk penelitian tindakan kelas (Classroom Action Research), guna mengetahui Penerapan Pembelajaran Kooperatif Model Student Team Achievement Division (STAD) untuk Meningkatkan Hasil Belajar IPA pada Konsep Benda Padat dan Cair Siswa Kelas III SD Negeri 45 Halmahera Selatan Berdasarkan penelitian dapat disimpulkan bahwa Hasil belajar siswa sebelum diberi pembelajaran dengan menggunakan model STAD menunjukan 20 siswa kelas III, 12 siswa mendaptkan nilai dibawah 60, dan 8 siswa mendapatkan nilai diatas 60. Secara keseluruhan rata-rata kelas 60,50. Data hasil penelitian masih kurang memuaskan, pada siklus I hasil belajar siswa melalui penerapan pembelajaran dengan menggunakan model STAD menunjukan dari 20 siswa kelas II, 8 siswa mendapatkan nilai dibawah 60, dan 12 siswa mendapatkan nilai diatas 60. Secara keseluruhan rata-rata kelas menjadi 60,50, data hasil penelitian pada siklus ini belum memuaskan, pada siklus II hasil belajar siswa melalui penerapan pembelajaran dengan menggunakan model STAD menunjukan dari 20 siswa kelas II, 2 siswa medapatkan nilai dibawah 60, dan 18 siswa mendapatkan nilai diatas 60. Secara keseluruhan rata-rata kelas menjadi 85,5.

Abstract

This research is Classroom Action Research (PTK) which aims to improve science-physics learning outcomes for expansion material in class VIII students at SMP Negeri 17 Halmahera Selatan for the 2024/2025 academic year through the use of an Inquiry Based Learning model. The research was carried out collaboratively and participatively, carried out in two cycles. Data collection in this research was carried out using participant observation and written tests. Based on the research results, it was concluded that the application of the Inquiry Based Learning model can improve students' science and physics learning outcomes. This is supported by research data which shows an increase in the percentage of completeness of the written test taken at the second meeting in each cycle. During the pre- cycle, learning completeness was only 42.85%, after implementing cycle 1 actions using the Inquiry Based Learning model, the percentage of students' learning completeness increased to 71.42%, then in cycle 2 actions, students' learning completeness reached 100%. The use of the Inquiry Based Learning model can also increase the learning activities of class VIII students at SMP Negeri 17 HalmaheraSelatan for the 2024/2025 academic year. Student activities consist of cooperation, responsibility and tolerance. In cycle 1, students' learning activities obtained a final score of 62%, meaning that students' learning activities were in good criteria. In cycle 2 the final score of student learning activities reached 88% so it was in the very good criteria
