Penelitian ini bertujuan untuk menganalisis perbedaan hasil belajar matematika siswa melalui pembelajaran pendekatan realistik dengan pembelajaran biasa, serta untuk mengetahui kesalahan yang dominan dilakukan oleh siswa melalui pendekatan realistik. Penelitian ini dilakukan di kelas VII MTs. Swasta Islamiyah Tanjung Kasau. Metode yang digunakan adalah quasi eksperimen. Sampel yang digunakan 22 siswa kelas VII-B dan kelas VII-A sebagai kelas eksperimen dan kontrol. Instrumen yang digunakan sebagai tes hasil belajar matematika adalah 5 soal berbentuk uraian. Dari hasil uji-t diperoleh nilai t hitung > t tabel (2,190 > 2,018) ,maka H0 ditolak. Sehingga hasil belajar matematika siswa kelas VII di MTs. Swasta Islamiyah Tanjung Kasau melalui pembelajaran pendekatan realistik lebih tinggi dibanding pembelajaran biasa. Dari hasil persentase rata-rata pada kategori kesulitan, didapat bahwa pada kelas eksperimen persentase rata-rata kategori kesulitan konseptual sebesar 21%, pada kategori kesulitan prosedural sebesar 30% dan kesulitan teknik sebesar 34%. Dugaan faktor penyebab kesulitan teknik adalah ketidakpahaman siswa mengeni operasi hitung campuran.

The difficulty of students in solving computational thinking (CT) problems related to the limit material of algebraic functions is that students do not understand the existing problems, difficulties regarding how the problem-solving pattern, difficulties when asked how to solve the problem, and difficulties when deciding and concluding from the problem. To overcome these difficulties, interactive multimedia is used, which is very important in modern education, it allows students to learn in a more interesting and interactive way, which can strengthen students' computational thinking skills. The purpose of this study was to determine the Exploration of Computational Thinking ability in the concept of Limit algebraic function with interactive multimedia and to determine the student's response to the use of interactive multimedia on the computational thinking ability of students in the material limit algebraic function in the department of tadris mathematics IAIN Lhokseumawe. The method used in this research is pre-experimental method, with the research design used is One Group Pretest-Posttest (Initial Test-Final Test on a single group. The research subjects were 1st semester students majoring in Tadris Metematics IAIN Lhokseumawe academic year 2023/2024. The research results obtained 1) From the calculation of the t test obtained the results of Tcount amounting to 2.583 and Ttable 1.684 (Ttest Ttable) or the probability value Sig 2 tailed α (0.000 0.05), then the hypothesis decision can be stated Ho rejected and Ha accepted. Thus, there is a significant difference in the exploration of computational thinking ability in the concept of limit function algebra with interactive multimedia. 2) the average percentage of very good categories obtained a value of 86%, good 13%, less 1%. The difference from the results of student responses with good to very good criteria is influenced by attitudes that show enthusiastic positive responses to interactive multimedia.

The purpose of this study was to determine the evaluation of computational thinking ability in understanding the limits of algebraic functions for students majoring in Tadris mathematics at Lhokseumawe State Islamic Institute. The research subjects were 1st semester students, totaling 6 students. Data collection techniques in this study used computational thinking ability tests and interviews, and then the data were analyzed based on computational thinking indicators, namely decomposition, pattern recognition, algorithm thinking, generalization, and abstraction. The results obtained from high computational thinking ability indicators that can be completed perfectly are decomposition, pattern recognition, algorithm thinking, and generalization/abtraction. With moderate computational thinking ability, students have been able to solve problems perfectly for indicators of decomposition and pattern recognition, but for indicators of thinking algorithms and generalizations or abstractions, they are still less precise. Low computational thinking ability has been able to measure decomposition indicators, but for pattern recognition indicators, thinking algorithms are still less precise in solving, while generalization and abstraction indicators do not answer.
