Abstract

Tujuan pembelajaran matematika adalah untuk melatih siswa berpikir kritis. Oleh karena itu, perlu dikembangkan Lembar Kerja Siswa (LKS) untuk melatih kemampuan berpikir kritis siswa. Penelitian ini bertujuan untuk menghasilkan LKS yang berkarakteristik untuk melatih kemampuan berpikir kritis siswa kelas VII SMP. Sampel pada penelitian ini adalah kelas VII7 berjumlah 30 siswa semester II SMP Negeri 9 Palembang. Metode penelitian yang digunakan adalah metode penelitian pengembangan yang terdiri dari analisis, desain, evaluasi dan revisi. Pengumpulan data dilakukan dengan cara prototyping. Prototyping dilakukan untuk mengetahui bagaimana karakteristik LKS untuk melatih kemampuan berpikir kritis siswa kelas VII SMP. Hasil penelitian ini adalah karakteristik LKS untuk melatih kemampuan berpikir kritis siswa kelas VII SMP. Kata kunci: Kemampuan berpikir kritis, Lembar Kerja Siswa Mathematics learning aims to develop students’ critical thinking. Therefore, it is necessary to develop Student Worksheet to train students' critical thinking skills. This research aims to develop student worksheet that has characteristics of critical thinking skill for 7th grade Junior High School students (SMP). The sample in this research is VII7 class with 30 students of the second semester of SMP Negeri 9 Palembang. The research method used is a development research method that consists of analysis, design, evaluation and revision. Data collection is done by prototyping. Prototyping was used to find out how the characteristics of student worksheet to develop critical thinking ability of grade 7th students. The result of this research is characteristic of student worksheet to develop critical thinking ability of 7th grade Junior High School student. Keywords: critical thinking ability, student worksheet

Abstract

The rapid development of technology must be utilized as well as possible, especially in the world of education, because education is the basis for forming individuals who are strong and able to compete in facing the challenges of the times. The habit of students using existing formulas without knowing the concept of the material causes them to have difficulty solving the same problem but in a different form of problem. Therefore, the development of electronic student worksheets based on Rigorous Mathematical Thinking (RMT) on the material of rows and series becomes an electronic teaching material that contains the stages of the learning process to build an in-depth understanding of the concepts of students as well as being one of the changes from existing technological developments. This study aimed to assess the validity and practicality of electronic student worksheets based on RMT developed. The research method used is Research and Development (R&D) with the 4D development model. The validity and practicality assessment instrument is a student questionnaire sheet with a Likert scale. The data obtained were analyzed using the percentage of the assessment score. The validation results show that electronic student worksheets are categorized as valid, with an average percentage of material validation of 88.13%, an average percentage of media validation of 94.62%, and an average percentage of language validation 93.64%. The practicality test obtained an average percentage of 78.39% in the practical category.
