Kemampuan pemecahan masalah matematis merupakan salah satu kompetensi yang penting dimiliki siswa dalam pembelajaran matematika. Namun, kemampuan tersebut masih tergolong rendah, terutama pada materi fungsi kuadrat. Oleh karena itu, diperlukan model pembelajaran yang mampu melibatkan siswa secara aktif, mendorong kolaborasi, serta memanfaatkan teknologi dalam proses pembelajaran. Penelitian ini bertujuan untuk mengetahui efektivitas model LC 5E berbasis Active Teamwork berbantuan Canva Whiteboard terhadap kemampuan pemecahan masalah matematis siswa pada materi fungsi kuadrat. Penelitian ini menggunakan pendekatan kuantitatif dengan metode quasi experiment dan desain Pretest-Posttest Control Group Design. Sampel penelitian terdiri atas siswa kelas X7 sebagai kelas eksperimen dan kelas X1 sebagai kelas kontrol. Data dikumpulkan melalui tes kemampuan pemecahan masalah matematis, observasi, dan dokumentasi. Analisis data dilakukan menggunakan uji normalitas, uji homogenitas, independent sample t-test, dan uji N-Gain. Hasil penelitian menunjukkan bahwa data kedua kelas berdistribusi normal dan homogen. Hasil uji hipotesis diperoleh nilai thitung sebesar 2,059 dan ttabel sebesar 1,994 pada taraf signifikansi 5%, sehingga thitung> ttabel. Selain itu, hasil analisis N-Gain menunjukkan nilai rata-rata sebesar 0,52 yang termasuk kategori sedang. Temuan penelitian menunjukkan bahwa kemampuan pemecahan masalah matematis siswa yang belajar menggunakan model LC 5E berbasis Active Teamwork berbantuan Canva Whiteboard lebih baik dibandingkan siswa yang mengikuti pembelajaran konvensional. Dengan demikian, model LC 5E berbasis Active Teamwork berbantuan Canva Whiteboard efektif digunakan untuk meningkatkan kemampuan pemecahan masalah matematis siswa pada materi fungsi kuadrat.

Abstract
Mathematical problem-solving ability is one of the essential competencies that students need to develop in mathematics learning. However, this ability remains relatively low, particularly in quadratic function material. Therefore, a learning model that actively engages students, promotes collaboration, and integrates technology into the learning process is needed. This study aimed to determine the effectiveness of the LC 5E model based on Active Teamwork assisted by Canva Whiteboard on students’ mathematical problem-solving ability in quadratic function material. The study employed a quantitative approach using a quasi-experimental method with a Pretest-Posttest Control Group Design. The sample consisted of students in class X7 as the experimental group, who were taught using the LC 5E model based on Active Teamwork assisted by Canva Whiteboard, and students in class X1 as the control group, who received conventional instruction. Data were collected through mathematical problem-solving tests, observations, and documentation. The data were analyzed using normality tests, homogeneity tests, an independent sample t-test, and N-Gain analysis. The results showed that the data from both groups were normally distributed and homogeneous. Hypothesis testing yielded a t-value of 2.059 and a t-table value of 1.994 at the 5% significance level, indicating that t-value > t-table value. Furthermore, the N-Gain analysis produced an average score of 0.52, which was categorized as moderate. The findings indicate that students who learned through the LC 5E model based on Active Teamwork assisted by Canva Whiteboard demonstrated better mathematical problem-solving ability than those who received conventional instruction. Therefore, the LC 5E model based on Active Teamwork assisted by Canva Whiteboard can be considered effective in improving students’ mathematical problem-solving ability in quadratic function material.
