Abstract

This study aims to determine the validity, practicality, and effectiveness of the development of the android multimedia "TRIGO-MEDIA" using the Auditory, Intellectually, Repetition (AIR) learning model to improve the mathematical problem-solving ability. This research is a development research using the ADDIE development model. The subjects of this study were students of classes X MIPA 1 and X MIPA 2 in SMA Negeri 2 Magelang. The results showed that the multimedia developed was in a very valid category with a percentage of 91.03% of the material validity and 90.41% of the media validity, multimedia was in a very practical category with a percentage of 82.54%. Then, multimedia meets the effective aspect with a significant difference between the control and experimental class (the average TKPMM value in the control class is 51.71 and the experimental class is 80.23). This can be concluded that the development of the Android multimedia "TRIGO-MEDIA" uses the learning model of the Auditory, Intellectually, Repetition (AIR) that is valid, practical, and effective to improve the mathematical problem-solving ability of students.

Abstract

The purpose of this study is to identify (1) effectiveness between the RME learning model and the direct learning on the ability to understand mathematical concepts, (2) the effect of different personality types on the ability to understand mathematical concepts (3) the interaction between learning models and personality types. to the ability to understand mathematical concepts. The design of this study used a quasi-experimental, namely the nonequivalent posttest-only control group. The population in study were all students of class VII SMP N 1 Magelang totaling 250 students. Sampling in study used the Cluster Random Sampling technique. Collecting data using a questionnaire and post-test. The data analysis technique in this study used a two-way analysis of variance with unequal cells, with the prerequisites of the analysis that normality was by the Liliefors test and homogeneity was by the Barlett test. Based on hypothesis testing, the results obtained are that (1) RME learning model is more efective than direct learning in the ability to understand mathematical concepts, (2) there is no effect of different personality types on the ability to understand mathematical concepts, (3) there is an interaction between the learning model and personality type. on the ability to understand mathematical concepts.

Abstract

This study aimed to analyze the effectiveness of the Somatic, Auditory, Visual, Intellectual (SAVI) learning and Problem-Based Learning (PBL) models in improving students' mathematical communication ability compared to direct learning. A quasi-experimental design was employed, with the SAVI learning model implemented in experimental class 1, PBL in experimental class II, and direct learning in the control class. The sample was selected using cluster random sampling, and data were collected through observations, interviews, and tests. Hypothesis testing, including proportion tests, one-way ANOVA, and Scheffe tests, revealed the following results: (1) students taught with the SAVI learning model demonstrated significant improvement in mathematical communication ability; (2) students instructed using the PBL model also exhibited substantial enhancement in mathematical communication ability; (3) notable differences were observed among the SAVI learning, PBL, and direct learning models, highlighting the effectiveness of both the SAVI learning and PBL models in enhancing mathematical communication ability. Moreover, the PBL model outperformed direct learning, while the SAVI learning model showed greater effectiveness than direct learning. Overall, this study provides evidence supporting the efficacy of the SAVI learning and PBL models in fostering students' mathematical communication skills.

Abstract

AbstrakDalam pendidikan modern, siswa harus memiliki keterampilan berpikir kritis yang didukung oleh kepercayaan diri dalam pembelajaran matematika. Salah satu masalah utama dalam penelitian ini adalah peningkatan keterampilan berpikir kritis sekolah menengah yang disebabkan oleh guru. Tujuan dari penelitian ini adalah untuk menilai seberapa efektif model pembelajaran berbasis masalah (PBL) untuk keterampilan berpikir kritis. Ini terjadi dengan kepercayaan sekolah menengah yang bangun datar. Studi ini menggunakan pendekatan kuantitatif dan desain kuasi-eksperimental. Secara khusus, desain kelompok kontrol hanya digunakan dalam desain faktorial 2x3 setelah pengujian. Populasi penelitian adalah siswa kelas VII SMP Negeri 3 Mojokerto tahun pelajaran 2024/2025 sebanyak 251 siswa, dengan sampel 61 siswa yang dipilih menggunakan cluster random sampling. Instrumen penelitian meliputi angket self-confidence dengan skala Likert dan tes kemampuan berpikir kritis berbentuk uraian pada materi bangun datar. Teknik pengumpulan data dilakukan melalui pemberian angket dan tes, kemudian dianalisis menggunakan uji prasyarat dan analisis variansi dua jalan. Hasil penelitian menunjukkan tidak terdapat perbedaan signifikan kemampuan berpikir kritis antara siswa yang belajar dengan PBL dan pembelajaran langsung (sig. = 0,422 > 0,05). Self-confidence juga tidak berpengaruh signifikan terhadap kemampuan berpikir kritis (sig. = 0,543 > 0,05), dan tidak terdapat interaksi antara model pembelajaran dan self-confidence (sig. = 0,227 > 0,05). Disimpulkan bahwa efektivitas PBL tidak lebih superior dibandingkan pembelajaran langsung dalam meningkatkan kemampuan berpikir kritis siswa pada konteks penelitian ini. AbstractTwenty-first-century education demands that students possess critical thinking abilities supported by self-confidence in mathematics learning. The low critical thinking ability of junior high school students, exacerbated by conventional teacher-centered learning, constitutes the main problem in this research. This study aims to analyze the effectiveness of the Problem Based Learning (PBL) model on critical thinking ability in terms of junior high school students' self-confidence in plane geometry material. The research method employed a quantitative approach with a quasi-experimental design, specifically the non-equivalent posttest-only control group design with a 2×3 factorial arrangement. The research population consisted of 251 seventh-grade students at SMP Negeri 3 Mojokerto in the 2024/2025 academic year, with a sample of 61 students selected using cluster random sampling. Research instruments included a self-confidence questionnaire using a Likert scale and a critical thinking ability test in essay form on plane geometry material. Data collection techniques were conducted through questionnaire administration and testing, then analyzed using prerequisite tests and two-way analysis of variance. The research results show no significant difference in critical thinking ability between students learning with PBL and direct instruction (sig. = 0.422 > 0.05). Self-confidence also had no significant effect on critical thinking ability (sig. = 0.543 > 0.05), and there was no interaction between learning model and self-confidence (sig. = 0.227 > 0.05). It is concluded that the effectiveness of PBL is not superior to direct instruction in improving students' critical thinking ability in the context of this research.
