Abstract

Penelitian ini bertujuan untuk mengidentifikasi kesalahan yang dilakukan siswa dalam menyelesaikan masalah cerita pada materi SPLDV berdasarkan prosedur Newman. Metode kualitatif deskriptif digunakan dalam penelitian ini. Data diperoleh melalui tes tertulis berupa soal cerita berdasarkan materi SPLDV, dan dilanjutkan dengan wawancara. Hasil temuan menunjukkan bahwa persentase siswa melakukan berbagai jenis kesalahan, mulai dari kesalahan membaca soal, kesalahan mentransformasikan soal, kesalahan keterampilan proses, hingga kesalahan penulisan jawaban akhir. Kesalahan terbesar sebesar 78,21% terjadi pada tahap kesalahan penulisan jawaban akhir dan kesalahan terkecil sebesar 26,92% terjadi pada tahap kesalahan membaca. Kesalahan tersebut disebabkan oleh beberapa faktor, seperti kesulitan dalam memahami maksud soal, kurang teliti dalam membaca soal, terburu-buru dalam mengerjakan soal, kebiasaan tidak menuliskan informasi dari soal yang diberikan, kurang memahami konsep soal. SPLDV, kesulitan menerapkan konsep materi yang telah dipelajari, waktu mengajar terbatas, siswa tidak mengikuti prosedur yang benar, dan tidak menulis jawaban akhir secara sistematis. Temuan ini diharapkan dapat memberikan pengetahuan mendalam bagi para pendidik dan guru dalam merancang strategi pembelajaran yang lebih baik untuk meningkatkan pemahaman siswa.

Abstract

At this time, computational thinking ability is very important because it can help humans in achieving success in the world of work and society is getting bigger. This preliminary study aims to identify and explore the computational thinking skills of junior high school students and the factors that influence them. The research method used was mixed methods by giving 3 description questions on linear function material that can measure computational thinking ability to 35 class IX students in one of the junior high schools in Sukabumi. The results showed that the highest score achieved by students was 91.67 while the lowest score was 16.67. The average score was 58.33 with 20 students above average and 15 students below average. The median test score was 58.33 with the modes being 44.44 and 61.11. After analyzing each student's answer, it was found that the computational thinking ability of junior high school students was at a low level. The test results stated that students were only capable of the problem decomposition and algorithm stages, not yet to the stages of pattern recognition and abstraction. Students tend to perform calculations directly after breaking down the problem into smaller parts and writing down sequential steps to solve the problem. This shows that mathematics learning in schools today is still lacking in directing students to computational thinking skills.

Abstract

The purpose of this study is to analyze and examine the effectiveness of learning implementation with a constructivist approach using video technology to integrate traditional culture as an effective step to increase students' ability to understand mathematical concepts. The research approach was used with literature from various relevant studies from 2019-2024. The research findings obtained are in the form of increasing student interaction and activeness in the mathematics learning process so that meaningful learning is obtained as a form of learning by integrating traditional culture as a learning medium to construct student knowledge by associating the material context close to the student's living environment, with video as an interactive media can foster a learning environment that facilitates the learning process self-sufficient. Improve students' ability to solve mathematical problems and think critically. This study also found a gap where not much research has been conducted by combining traditional cultural content with technology because there is still a lack of ability to manage learning related to technology content. This study recommends that constructive learning with traditional culture through interactive videos can be applied in the context of mathematics learning. Validate the data by comparing research results from various journals, reports, or related articles

Abstract

Mathematical problem-solving abilities are important to support the development of 4C skills (Communication, Collaboration, Critical Thinking, Problem-Solving, Creativity, and Innovation) in the 21st century. However, in reality, students' ability to solve problems is still relatively low and does not meet expectations. This research aims to identify students' mathematical problem-solving abilities in solving System of Equations in Two Variables (SPLDV) problems. The research method used is descriptive quantitative, with data collection through tests in the form of descriptions. The population of this study was all students in class VIII in one of the junior high schools in Sukabumi Regency, with a sample taken of 24 students from class VIII. The research results showed that the average student score was 34.5, with the majority of students being in the low category at 87.5%, and only a few students were able to reach the medium category with a percentage of 4.17% and high with a percentage of 8.33%. Analysis of the problem-solving stages shows that although 70.83% of students were able to understand the problem, 41.67% could plan the problem, only 12.5% succeeded in solving the problem, and 8.34% could check the solution. These results also show that the students' mathematical problem-solving abilities in solving System of Equations in Two Variables (SPLDV) problems at this school are mostly in the low category and still need a lot of improvement.
