Nazariani, Septia (2024). Implementasi Model CoCoAER Untuk Meningkatan Pemahaman Konsep Fisika Siswa pada Pelaksanaan Kurikulum Merdeka, Jurusan Pendidikan Fisika, Fakultas Keguruan dan Ilmu Pendidikan, Universitas Syiah Kuala. Dibawah bimbingan Dr. Zainuddin, M.Pd dan Dra. Nurulwati, M.Pd, CIT

Rendahnya pemahaman konsep fisika disebabkan oleh pemilihan model dan media pembelajaran yang kurang tepat serta pendekatan pengajaran yang terlalu berfokus pada penyelesaian soal-soal hitungan, sehingga siswa merasa kesulitan memahami materi yang diajarkan. Penelitian ini bertujuan untuk mengetahui peningkatan pemahaman konsep fisika siswa melalui implementasi model CoCoAER pada pelaksanaan kurikulum merdeka. Penelitian ini menggunakan jenis penelitian Pre Experimental Design dengan pola One Group Pretst-Posttest. Populasi dalam penelitian ini adalah seluruh siswa kelas XI SMAN 8 Banda Aceh, dengan Sampel yaitu kelas XI A 2-3 yang berjumlah 31 orang dengan menggunakan teknik purposive sampling. Teknik Pengolahan data menggunakan N-Gain Score. Hasil analisis data dikelompokkan menjadi 3 yaitu analisis kevalidan, kepraktisan dan keefektifan. Hasil analisis kevalidan diperoleh dari instrumen non-tes dan tes dengan kategori valid (V). sementara hasil analisis kepraktisan rata-rata tergolong dalam kategori sangat baik (SB). Sedangkan hasil analisis keefektifan ditinjau dari analisis deskripsi paham konsep, belum paham konsep, miskonsepsi, uji N-Gain, serta angket respon siswa. Setelah diajarkan dengan model CoCoAER, siswa berkategori paham konsep meningkat menjadi 67,7%-90,3%, siswa berkategori belum paham konsep berkurang menjadi 3,2%-25,8%, siswa berkategori miskonsepsi berkurang menjadi 0,0%-12,9%. Dengan demikian dapat dinyatakan bahwa model CoCoAER dapat meningkatan pemahaman konsep siswa dengan score N-Gain 0,74

Nazariani, Septia (2024). Implementation of the CoCoAER Model to Improve Students' Understanding of Physics Concepts in the Implementation of the Merdeka Curriculum, Department of Physics Education, Faculty of Teacher Training and Education, Syiah Kuala University. Under direction of Dr. Zainuddin, M.Pd and Dra. Nurulwati, M.Pd, CIT The low understanding of physics concepts is caused by the selection of inappropriate learning models and media as well as a teaching approach that focuses too much on solving calculation problems, so that students find it difficult to understand the material being taught. This study aims to determine the improvement of students' understanding of physics concepts through the implementation of the CoCoAER model in the implementation of the independent curriculum. This research uses the Pre Experimental Design research type with the One Group Pretst-Posttest pattern. The population in this study were all students of class XI SMAN 8 Banda Aceh, with the sample being class XI A 2-3 which amounted to 31 people using purposive sampling technique. Data processing techniques using N-Gain Score. The results of data analysis are grouped into 3 namely analysis of validity, practicality and effectiveness. The results of the validity analysis were obtained from non-test and test instruments with a valid category (V). while the average practicality analysis results were classified in the very good category (SB). While the results of the effectiveness analysis were reviewed from the analysis of the description of understanding the concept, not understanding the concept, misconceptions, N-Gain test, and student response questionnaire. After being taught with the CoCoAER model, students categorized as understanding the concept increased to 67.7%-90.3%, students categorized as not understanding the concept decreased to 3.2%-25.8%, students categorized as misconceptions decreased to 0.0%-12.9%. Thus it can be stated that the CoCoAER model can increase students' concept understanding with an N-Gain score of 0.74 Keywords: Concept Understanding, CoCoAER Model, Physics Concept
