Rendahnya tingkat pemahaman konsep fisika pada siswa SMA masih menjadi
tantangan dalam dunia pendidikan. Observasi awal di SMA Negeri 12 Banda Aceh
menunjukkan bahwa masih ada siswa belum mencapai Kriteria Ketuntasan Tujuan
Pembelajaran (KKTP), serta proses pembelajaran banyak dilakukan didalam kelas
dan kurangnya kegiatan eksperimen. Hal ini berdampak pada rendahnya
kemampuan siswa dalam konsep fisika dengan fenomena nyata. Penelitian ini
bertujuan untuk mengetahui adanya peningkatan pemahaman konsep fisika
dengan model pembelajaran CoCoAER berbantuan Investigative Science Learning
Environment (ISLE) pada konsep fisika SMA. Pendekatan yang digunakan adalah
metode campuran dengan desain pre-eksperimental menggunakan model One
Group Pretest-Posttest. Sampel dalam penelitian ini sebanyak 32 siswa kelas XI
IA 1 yang dipilih secara purposive sampling. Instrumen yang digunakan meliputi
tes pemahaman konsep Three Tier Test, lembar pengamatan keterlaksanaan
pembelajaran, serta angket respon siswa. Teknik analisis data menggunakan NGain, hasilnya 0,7237 termasuk kategori tinggi, sehingga dapat meningkatkan
pemahaman konsep fisika dengan model CoCoAER berbantuan ISLE pada siswa
SMA.

Najmus Suraiya. (2025). Improving Physics Conceptual Understanding through the CoCoAER Model Assisted by the Investigative Science Learning Environment (ISLE) in Senior High School Physics. Skripsi. Universitas Syiah Kuala. Under direction of Dr. Drs. Zainuddin, M.Pd and Dra. Elisa, M.Si. The low level of conceptual understanding in physics among high school students remains a challenge in the field of education. Initial observations at SMA Negeri 12 Banda Aceh show that some students have not yet achieved the Minimum Learning Mastery Criteria (KKTP), and the learning process is mostly conducted inside the classroom with a lack of experimental activities. This condition negatively affects students’ ability to relate physics concepts to real-world phenomena. This study aims to determine the improvement in students’ conceptual understanding of physics through the CoCoAER learning model assisted by the Investigative Science Learning Environment (ISLE) on high school physics concepts. A mixed-methods approach was used with a pre-experimental design employing the One Group Pretest-Posttest model. The sample consisted of 32 students from class XI IA 1, selected through purposive sampling. The instruments used included a Three-Tier Test to assess conceptual understanding, an observation sheet for learning implementation, and a student response questionnaire. Data analysis was conducted using the N-Gain technique, with a result of 0.7237 categorized as high. Therefore, the CoCoAER model assisted by ISLE can improve students’ conceptual understanding of physics in high school. Keywords: CoCoAER Model, Conceptual Understanding, ISLE.
