Abstract

Kemampuan berpikir kreatif perlu dimiliki oleh siswa dalam pembelajaran matematika. Penelitian ini bertujuan untuk menganalisis kemampuab berpikir kreatif siswa SMP pada materi Bangun Ruang Sisi Datar Kubus dan Balok. Metode penelitian ini adalah deskriptif kualitatif. Penentuan subjek penelitian dilakukan secara Purposive Sampling dengan memilih 3 orang siswa kelas VIII. Data diperoleh dengan cara melakukan tes tertulis, wawancara, dan observasi. Setiap data atau informasi yang diperoleh dianalisis dalam bentuk deskriptif. Kemampuan berpikir kreatif yang dimiliki siswa dianalisis berdasarkan indikator-indikator kemampuan berpikir kreatif. Hasil penelitian ini adalah keempat indikator kemampuan berpikir kreatif siswa perlu ditingkatkan karena belum optimal. Faktor-faktor yang mempengaruhi kemampuan berpikir kreatif yaitu proses pembelajaran, pemahaman siswa, serta pemberian latihan soal. Creative thinking skills are essential for students in learning mathematics. This study aims to analyze the creative thinking abilities of junior high school students in the topic of Three-Dimensional Shapes, specifically cubes and rectangular prisms. The research method used is qualitative descriptive. The selection of research subjects was conducted using purposive sampling, involving three eighth-grade students. Data were collected through written tests, interviews, and observations. All obtained data or information were analyzed descriptively. Students' creative thinking skills were analyzed based on specific indicators of creative thinking ability. The results of this study show that all four indicators of students' creative thinking skills need improvement, as they are not yet optimal. Factors influencing creative thinking skills include the learning process, students' comprehension, and the provision of practice problems.

Abstract

It is important to continue developing digital mathematics learning media. This research was conducted to develop learning media assisted by Google Sites on the material Systems of Linear Equations in Two Variables and to analyze the feasibility of this learning media. This research is descriptive research with the research and development method of the ADDIE model which consists of 5 stages, namely analysis, design, development, implementation and evaluation. The subjects for this learning media trial were 39 students in class VIII of one of the private junior high schools in Garut Regency. Based on the research results, this media meets the criteria for validity and practicality as a learning media product. This is known from: (1) the validity of learning media, which is based on the results of an assessment of the validity of the media and material, showing valid results with revision, with a material achievement percentage of 92.7% and a media achievement percentage of 83.3%; (2) the practicality of learning media, as assessed from the student response questionnaire, obtained a percentage of 74.25%, indicating results that fall into the practical category.

Abstract

Kemampuan komunikasi matematis dan kepercayaan diri siswa masih rendah. Hal ini disebabkan proses pembelajaran yang monoton dan siswa tidak aktif terlibat dalam proses pembelajaran, sehingga membutuhkan media pembelajaran yang efektif untuk meningkatkan kemampuan komunikasi matematika dan kepercayaan diri siswa. Penelitian ini dilakukan untuk mengembangkan media pembelajaran berbasis Google Sites pada materi Geometri Bangun Ruang dan untuk menganalisis validitas, kepraktisan, dan efektivitas media pembelajaran tersebut. Penelitian ini merupakan studi penelitian dan Pengembangan (RnD) dengan menggunakan model ADDIE. Instrumen yang digunakan dalam penelitian dan pengembangan ini adalah kuesioner, tes kemampuan komunikasi matematis, dan lembar observasi. Subjek percobaan adalah siswa kelas delapan SMP Swasta di Kabupaten Garut. Hasilnya diketahui bahwa media pembelajaran berbasis Google Sites memenuhi kriteria validitas, kepraktisan, dan efektivitas dalam meningkatkan kemampuan komunikasi dan kepercayaan diri siswa. Hal ini diketahui dari validitas media pembelajaran, berdasarkan hasil penilaian validitas media dan materi, menunjukkan hasil yang valid; kepraktisan media pembelajaran, menunjukkan hasil yang termasuk dalam kategori praktis; efektivitasnya dalam meningkatkan kemampuan komunikasi matematis diperoleh dari hasil tes yang menunjukkan peningkatan dengan interpretasi sedang dan tinggi; efektivitasnya dalam meningkatkan kepercayaan diri siswa diperoleh dari peningkatan dengan interpretasi sedang. Students' mathematical communication ability and self-confidence are still low. This is due to the learning process being monotonous and students not being actively involved in the learning process, thus requiring effective learning media to improve students' mathematical communication ability and self-confidence. This research was conducted to develop Google Sites-assisted learning media on the Geometry of Solid Shapes material and to analyze the validity, practicality, and effectiveness of the learning media. This research is a Research and Development (RnD) study using the ADDIE model. The instruments used in this research and development are questionnaires, mathematical communication ability tests, and observation sheets. The subjects of the trial were eighth-grade students of a Private Junior High School in Garut Regency. The result is known that the Google Sites-assisted learning media meets the criteria for validity, practicality, and effectiveness in improving students' communication ability and self-confidence. This is known from: the validity of the learning media, based on the assessment results of the media and material validity, showed valid results; the practicality of the learning media, showed results that fall into the practical category; its effectiveness in increasing mathematical communication ability was obtained from an increase with moderate and high interpretation; its effectiveness in increasing students' self-confidence was obtained from an increase with moderate interpretation.
