Abstract

Critical thinking skills are very important in today's life, as other thinking skills develop, such as decision making and problem solving skills.This study aims to analyze the critical thinking skills of class VII students at SMPN 2 Kalisat in solving word problems on triangle material. Students' critical thinking skills are very important to help them solve problems and make the right decisions. This study used a descriptive qualitative method with data collection techniques using written tests and interviews. The research sample consisted of 6 students of class VII B at SMPN 2 Kalisat. The results showed that students' critical thinking skills in solving triangle story problems were still low. This shows the need for efforts to improve students' critical thinking skills through more active, creative and participatory learning. It is recommended for teachers to provide more exercises to students to improve their critical thinking skills in solving triangle story problems.Kemampuan berpikir kritis sangat penting dalam kehidupan saat ini, saat keterampilan berpikir lainnya berkembang, seperti pengambilan keputusan dan keterampilan memecahkan masalah. Penelitian ini bertujuan untuk menganalisis kemampuan berpikir kritis siswa kelas VII di SMPN 2 Kalisat dalam menyelesaikan soal cerita pada materi segitiga. Kemampuan berpikir kritis siswa sangat penting untuk membantu mereka dalam memecahkan masalah dan membuat keputusan yang tepat. Penelitian ini menggunakan metode kualitatif deskriptif dengan teknik pengumpulan data menggunakan tes tulis dan wawancara. Sampel penelitian terdiri dari 6 siswa kelas VII B di SMPN 2 Kalisat. Hasil penelitian menunjukkan bahwa kemampuan berpikir kritis siswa dalam menyelesaikan soal cerita materi segitiga masih rendah. Hal ini menunjukkan perlunya upaya untuk meningkatkan kemampuan berpikir kritis siswa melalui pembelajaran yang lebih aktif, kreatif, dan partisipatif. Disarankan bagi guru untuk memberikan latihan-latihan yang lebih banyak kepada siswa untuk meningkatkan kemampuan berpikir kritis mereka dalam menyelesaikan soal cerita materi segitiga.

Abstract

This study aims to investigate how the use of Augmented Reality (AR) impacts students' self-assessment skills in mathematics learning. Students are given the ability to assess themselves, which is very important to help them become independent learners and critical thinkers. A quasi-experimental design with a pretest-posttest control group was used. All 72 grade XI students in the sample were divided into experimental and control groups. Self-assessment tests and questionnaires were the tools used. The results of the analysis showed that, compared to the control class, students' self-assessment skills in the experimental class increased significantly. The results showed that AR was able to increase students' awareness in assessing their own understanding; the experimental group had a higher average self-assessment. Based on these findings, it can be concluded that AR has a positive effect on students' self-assessment skills. Therefore, it is recommended that AR be incorporated into mathematics learning to support students' metacognitive skills.

Abstract

Kemampuan literasi numerasi siswa SMP masih rendah. Diperlukan media untuk memfasilitasi peningkatan literasi numerasi, misalnya dengan E-booklet berbasis matematika realistik. Penelitian ini bertujuan mendeskripsikan proses pengembangan dan validitas, serta kepraktisan efektivitas pengembangan E-Booklet berbasis matematika realistik terhadap kemampuan literasi matematis siswa. Model penelitian dan pengembangan dalam penelitian ini menggunakan model ADDIE (Analyze, Design, Development, Implementation, Evaluation). Penelitian dilakukan pada salah satu SMPN di Siliragung. Subjek penelitian dipilih dengan teknik purposive sampling. Data dikumpulkan melalui wawancara, kuesioner, dan tes. Analisis data menggunakan uji-t untuk mengetahui peningkatan kemampuan literasi matematis siswa. Hasil penelitian ini berupa e-booklet berbasis matematika realistik pada materi perbandingan dengan kriteria valid dengan rerata presentase validitas sebesar 93%. E-booklet ini dinyatakan praktis digunakan dalam proses pembelajaran dengan perolehan rerata kepraktisan sebesar 80% dan dinyatakan efektif dalam meningkatkan kemampuan literasi matematis siswa. E-booklet berbasis matematika realistik memenuhi kevalidan, kepraktisan dan keefektifan sehingga layak digunakan sebagai media pembelajaran. The numeracy literacy ability of junior high school students is still low. Media is needed to facilitate the improvement of numeracy literacy, for example with realistic mathematics-based E-booklets. This study aims to describe the development process and validity, as well as the practicality of the effectiveness of developing realistic mathematics-based E-Booklets on students' mathematical literacy abilities. The research and development model in this study uses the ADDIE model (Analyze, Design, Development, Implementation, Evaluation). The study was conducted at one of the junior high schools in Siliragung. The research subjects were selected using purposive sampling techniques. Data were collected through interviews, questionnaires, and tests. Data analysis used the t-test to determine the improvement of students' mathematical literacy abilities. The results of this study were in the form of realistic mathematics-based e-booklets on comparative material with valid criteria with an average validity percentage of 93%. This e-booklet was declared practical to use in the learning process with an average practicality of 80% and was declared effective in improving students' mathematical literacy abilities. Realistic mathematics-based e-booklets meet validity, practicality and effectiveness so they are suitable for use as learning media.
