Abstract

This study aims to test the effectiveness of a Realistic Mathematics Education (RME)-based learning design in stimulating critical thinking and numeracy literacy in Islamic Junior High School (Islamic Junior High School) students. This study used a quantitative method with a quasi-experimental Non-Equivalent Control Group design. The subjects consisted of seventh-grade students divided into an experimental class and a control class. The experimental class implemented the RME learning design, assisted by worksheets (LKPD), which emphasized progressive mathematization processes through the stages of model-of, model-for, and formal representation, while the control class used conventional learning. The research instrument was a descriptive test of numeracy literacy and critical thinking, which had been tested for validity and reliability. The results of the N-Gain analysis showed an increase in student abilities in the moderate category, with the experimental class achieving higher achievement than the control class, although the difference was not statistically significant. These findings indicate that the RME learning design has the potential to improve students' activeness, critical reasoning, and contextual numeracy understanding, but requires a longer implementation period to have a significant impact.   Penelitian ini bertujuan dan menguji efektivitas desain pembelajaran berbasis Realistic Mthematics Education (RME) dalam menstimulasi kemampuan berpikir kritis dan literasi numerasi siswa Madrasah Tsanawiyah. Penelitian ini menggunakan metode kuantitatif dengan desain quasi eksperimen tipe Non-Equivalent Control Group. subjek penelitian terdiri atas siswa kelas VII yang dibagi ke dalam kelas eksperimen dan kelas kontrol. Kelas eksperimen menerapkan desain pembelajaran RME berbantuan LKPD yang tekanan proses matematisasi progresif melalui tahapan model-of, model-for, dan representasi formal, sedangkan kelas kontrol menggunakan pembelajaran konvensional. Instrumen penelitian berupa tes uraian literasi numerasi dan berpikir kritis yang telah diuji validitas dan reliabilitasnya. Hasil analisis N-Gain menunjukkan peningkatan kemampuan siswa pada kategori sedang, dengan pencapaian kelas eksperimen lebih tinggi di bandingkan kelas kontrol, meskipun perbedaannya belum signifikan secara statistik. Temuan ini menunjukkan bahwa desain pembelajaran RME berpotensi meningkatkan keaktifan, penalaran kritis, dan pemahaman numerasi kontekstual siswa, namun memerlukan durasi implementasi yang lebih panjang agar berdampak signifikan

Abstract

Pembelajaran matematika sering kali terputus dari pengalaman nyata siswa, membuat mereka kesulitan memahami konsep abstrak, seperti bilangan bulat dan operasinya. Ketidakpahaman siswa terhadap bilangan positif, negatif, serta operasi aritmetika sering menjadi hambatan utama dalam pembelajaran. Pendekatan PMRI menggarisbawahi pentingnya menggunakan konteks dunia nyata untuk menjembatani pemahaman ini, dengan permainan tradisional jejmok. Penelitian ini bertujuan untuk mengembangkan dan menguji Desain Local Instruction Trajectory (LIT) berbasis permainan tradisional Jejamok, untuk mengajarkan operasi bilangan bulat. Selain itu, penelitian ini menganalisis pengaruh pembelajaran berbasis permainan terhadap penguasaan konsep bilangan bulat siswa serta mengevaluasi peran lesson study dalam meningkatkan kualitas perancangan dan implementasi aktivitas pembelajaran berbasis permainan pada siswa kelas 6 SDIT Insan Rabbani, Kotabumi, Lampung Utara. Penelitian ini menggunakan metode Design Research dengan pendekatan kualitatif. Tipe penelitian yang digunakan adalah Validation Studies dengan tiga tahap utama: Preparing for the Experiment, Design Experiment, dan Retrospective Analysis. Teknik pengumpulan data meliputi observasi, wawancara, dan tes Teknik analisis data mengikuti model Miles dan Huberman yang mencakup reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian sebanyak 82% siswa telah menunjukkan penguasaan konsep. Hal ini berarti pendekatan berbasis permainan tradisional Jejamok efektif dalam meningkatkan pemahaman siswa terhadap konsep bilangan bulat. Lesson study berperan signifikan dalam menyempurnakan desain pembelajaran, melalui proses kolaborasi antara guru, peneliti, dan rekan sejawat. Penelitian ini mendukung temuan sebelumnya yang menyatakan bahwa pembelajaran berbasis konteks budaya lokal dan kolaborasi dalam lesson study dapat meningkatkan efektivitas pengajaran konsep matematika

Abstract

This study examines the effect of implementing a GeoGebra-assisted Problem Based Learning (PBL) model on students’ mathematical problem solving abilities. It was motivated by students’ low initial performance in solving problems, as indicated by pretest scores below the minimum mastery criterion, highlighting the need for innovative, technology integrated instruction. This study adopted a quantitative method employing a quasi experimental design with a pretest posttest control group. The participants were 42 seventh grade students at SMP Negeri 2 Abung Surakarta, with 22 in the experimental group (Class VII A) and 20 in the control group (Class VII B), selected via purposive sampling. The intervention spanned five sessions on the topic of squares, with the experimental group receiving GeoGebra assisted PBL instruction and the control group receiving conventional teaching. Data were collected through problem solving tests and analyzed using normality and homogeneity tests, N-gain analysis, and independent samples t-tests. Results showed that the experimental group achieved a higher average N-gain (0.608) than the control group (0.444), and the t-test indicated a significant difference , ? = 0.05). These findings confirm that the GeoGebra assisted PBL model effectively enhances students’ mathematical problem solving skills and supports the use of technology integrated learning in teaching squares at the junior high school level.

Abstract

Penelitian ini bertujuan untuk menginvestigasi pengaruh penggunaan media GeoGebra terhadap kemampuan berpikir spasial siswa kelas IX SMPN1 Kotabumi pada materi translasi. Permasalahan utama yang melatarbelakangi penelitian ini adalah rendahnya kemampuan visualisasi siswa, di mana hasil observasi awal menunjukkan hanya 30% siswa yag mampu menentukan koordinat trasnlasi dengan akurat. Metode penelitian yang digunakan adalah kuantitatif dengan desain eksperimen semu (nonequivalent control group design). Sampel penelitian ini terdiri dari 50 siswa yang terbagi ke dalam dua kelompok, yaitu kelas eksperimen 25 siswa denganbantuan GeoGebra dan kelas kontrol 25 siswaa melalui pembelajaran konvensional. Data dikumpulkan melalui instrumen tes esai yang mencakup lima indikator kemampuan spasial. Setelah data terkonfirmasi berdistribusi normal dan homogen, analisis hipotesis dilakukan menggunakan uji t-independen. Hasil penelitian menunjukkan adanya perbedaan signifikan pada capaian belajar kedua kelompok, di mana rata-rata skor N-Gain kelas eksperimen (0,246) lebih tinggi dibandingkan kelas kontrol (0,152). Temuan ini memperkuat penolakan hipotesis nol ) dan menegaskan bahwa integrasi GeoGebra memberikan dampak positif yang nyata. Sifat visual perangkat lunak yang dinamis mampu menjembatani hubungan antara aturan simbolik dan representasi visual secara konkret. Dengan demikian, dapat disimpulkan bahwa GeoGebra merupakan media pembelajaran yang efektif untuk mengasah kemampuan berpikir spasial siswa dalam pendidikan matematika.

Abstract

The objective of this study is to examine the effect of implementing the Project Based Learning (PjBL) model on the collaboration skills of Grade X students at SMK Negeri 1 Abung Selatan. The method employed was a quasi-experimental design with a pretest–posttest structure involving both an experimental class and a control class. Collaboration skill data were collected through questionnaires and authentic assessments. The analysis process included normality tests, homogeneity tests, t-tests, and N-Gain calculations. The findings revealed that although the N-Gain scores from the questionnaires in the experimental class showed greater achievement compared to the control class, the authentic assessment results were actually higher in the control class. The t-test indicated no significant difference between the two groups, suggesting that the application of PjBL did not lead to a meaningful improvement in collaboration skills. This condition was influenced by limited project time, suboptimal role distribution, and students’ adaptation process to the new learning method. More structured project planning is recommended for future research
