Abstract

The purpose of this study was to determine the mathematical representation ability of educated people in the linear buying system using Palembang culinary context questions. This research uses a type of qualitative research with a descriptive approach. The research subjects were students of class XI IPA SMA, totaling 3 people. The data collection techniques used were written tests and interviews. The questions on the written test are of the type of description questions, which consist of 2 questions using the culinary context of Palembang, where the first question uses the context of lamington cake and the second question uses the context of pempek. Data analysis is done by collecting data, reducing it, presenting it, and drawing conclusions from it. The results of the research were that there were two subjects who were able to change the given problem into the form of a mathematical model so that their mathematical representation skills emerged successfully, and one subject was unable to generate mathematical representation abilities because they had not been able to change the given problem into a mathematical model form.

Abstract

Computational Thinking (CT) is a very important skill for everyone because it is not only for solving problems related to computer science and mathematics, but also for solving various problems in everyday life. The application of computational thinking skills in Indonesia is still constrained which results in low computational thinking skills of students. This study aims to identify the ability of computational thinking in students through learning videos containing problem solving using the stages of computational thinking developed on the material of exponential equations. This study used descriptive qualitative methodology with 34 grade 10 learners in one of the high schools in Palembang as research subjects, focusing on three learners who showed high, medium, and low abilities. The research was conducted in three stages: preparation, implementation, and data analysis. Data were collected through written tests and interviews to measure learners' computational thinking ability. The results were analyzed through three stages, namely: data reduction, data presentation, and conclusion drawing. The results showed that learners showed proficiency in exponential material, especially in terms of pattern recognition and abstraction. However, in decomposition and algorithm skills, learners show a lack of ability in solving problems with a systematic approach and accurate solutions.

Abstract

Hasil belajar menunjukkan perkembangan siswa dalam hal pengetahuan (ingat, pahami, terapkan, dan seterusnya), sikap (menerima, berpartisipasi, dan lain-lain), serta keterampilan (persepsi, gerakan, dan kreativitas) setelah mengikuti pembelajaran. kenyataan di lapangan menunjukkan bahwa masih banyak siswa yang mengalami kesulitan dalam mempelajari matematika yang membuat hasil belajar mereka rendah. khususnya pada materi-materi yang dianggap abstrak. tujuan penelitian ini untuk meningkatkan hasil belajar peserta didik kelas XI.9 materi fungsi nilai mutlak menggunakan Gimkit. Jenis penelitian ini adalah penelitian tindakan kelas (PTK). Penelitian ini dilaksanakan di SMA Negeri 8 Palembang Tahun Pelajaran 2023/2024. Subjek dalam penelitian ini adalah peserta didik kelas XI.9 sebanyak 34 orang. Dalam penelitian tindakan kelas ini akan dilaksanakan melalui beberapa siklus yaitu siklus I dan siklus II. Berdasarkan hasil penelitian didapat terjadinya peningkatan hasil belajar matematika siswa dengan media pembelajaran menggunakan Gimkit. Hal ini ditunjukkan dengan perolehan nilai hasil belajar matematika pada siklus I yang terdiri dari nilai rata-rata siswa sebesar 78.08 dan persentase ketuntusan sebesar 70.59%. Dan peningkatan nilai hasil belajar matematika siswa diperoleh pada siklus II yaitu nilai rata-rata siswa sebesar 87.06 dan persentase ketuntusan sebesar 100%.

Abstract

Computational thinking is an important skill to have because it can help students to analyze and solve problems in a systematic, logical, and creative way, both in the world of computing and in everyday life. This study aims to identify the ability of computational thinking in students through problem-based learning on exponential topics. This study used descriptive qualitative method with 34 grade 10 students in one of the high schools in Palembang as research subjects, focusing on 3 students who have high, medium, and low abilities. The research was conducted in three stages: preparation, implementation, and data analysis. Data were collected through written tests and interviews to measure learners' computational thinking skills. The results were analyzed through three stages: data reduction, data presentation, and conclusion drawing. The results showed that students' computational thinking ability on exponential material was good in terms of pattern recognition and abstraction. However, for decomposition and algorithm skills, students still do not show their ability to solve problems systematically with the right answers.
