Application of Cooperative Learning Type Group Investigation to Improve Physics learning Outcomes in Vocational Schools

Abstract

This study proposes to analyze the differences in learning outcomes of pupils, who learn cooperative learning models of group investigation and conventional learning. The research sample consisted of class X a (30 people) who learned the cooperative learning model of the group investigation model and class X b (30 people) taught using conventional learning models with the topic of learning is basic electronic (capacitors). The sampling technique uses random sampling with a non-equivalent control group design. Data collection techniques consisted of written tests, observation sheets and documentation. Meanwhile, research instrument used achievement test (objective criteria) in the form of multiple-choice questions that comprise as many as 25 of the given level (C 1), understanding (C 2) applying (C 3) and analyzed. Students' test results were analyzed using descriptive statistical data analysis and inferential statistical data analysis. The analysis results obtained that there is a difference of learning outcomes between the experimental class and a control class with an average of 80.8 to 69.6 for the control class and experimental class. From the analysis, it was found that there was no significant difference between the experimental and control classes based on the N-gain value. So it can be concluded that the group investigation learning model does not have a significant effect on improving student learning outcomes.

Pengaruh Kualitas Pelaksanaan Program Musyawarah Guru Mata Pelajaran Terhadap Peningkatan Kompetensi Profesional Guru Fisika Tingkat SMA

“…Yunas & Rachmawati, (2018) mengatakan bahwa guru yang memiliki kemampuan mengajar sesuai karakter pribadi guna untuk membantu siswa-siswa belajar adalah guru yang telah mencapai tujuan pengajaran. Peran utama guru adalah mengajar siswa, khususnya melatih siswa untuk aktif belajar sehingga dapat meningkatkan kemampuan secara kognitif, afektif, dan psikomotor secara optimal (Benly et al, 2020). Hal ini membuktikan bahwa guru memiliki peranan penting bagi siswa untuk meningkatkan kemampuan dan keterampilannya dalam bidang pelajaran apapun.…”

Experimentation of cooperative learning model with group investigation type on communication ability and mathematical disposition

“…Education is an essential role in creating generations that have high quality (Benly, 2020), intelligence (Tang, 2020), creativity (Picard, 2020), Skills (Samaher, 2021), productivity (Nugroho et al, 2018), as well as being responsible and virtuous for development in advancing the nation and state (Abildgaard et al, 2021) so that it can become a guide in society and can compete with other countries in all fields (Graven, 2016;Suneki, 2020). In this case, all parties, especially the state, must provide quality learning (Abildgaard et al, 2021).…”
