Abstract

The effectiveness of implementing online learning during the COVID-19 pandemic has not been satisfactory in terms of problem-solving abilities. The presentation of teaching materials presented in the online platforms used has not been able to identify the extent of student understanding in problem-solving exploration. Therefore, this research aims to produce Kaizala teaching materials based on problem-solving exploration. The ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model was used in this research to produce these teaching materials. The subjects of this research trial were grade VIII junior high school students in a public school in Ogan Komering Ulu Regency, Palembang. The choice of the place for this research was based on the fact that the mathematics learning carried out at the school was by utilizing social media platforms. The instruments used in this research consisted of validation sheets of material, language, presentation, and problem-solving integration, a questionnaire on the practicality of teaching materials, and a problem-solving ability test to assess the effectiveness of the developed teaching materials. The results showed that: (1) the developed teaching materials were in the valid criteria; (2) the practicality of the developed teaching materials are at very high and high criteria; (3) The developed teaching materials also meet the criteria of effectiveness, whereas many as 82 percent of the test subjects obtained a score of not less than 75 and the effect size value belongs to the large category. Thus, it can be concluded that the developed teaching materials are suitable for supporting and facilitating students in problem-solving exploration activities.

Abstract

Mathematics aims to make students have good problem-solving skills based on the junior high school curriculum. However, the reality in the field is that more than 50% of students cannot solve problem-solving problems. This study aims to (1) Analyze the differences in the improvement of the problem-solving abilities of students who received learning with the GeoGebra-assisted CPS model and the problem-solving skills of students who received conventional learning in terms of overall and early mathematics ability (superior and low); (2) Analyzing the differences in learning interest of students who received GeoGebra-assisted CPS learning and students who received conventional understanding; (3) Analyzing the correlation between problem-solving abilities and students' interest in education. The research design employed was sequential explanatory with a quasi-experimental method. The Instruments were written tests, questionnaires, observation sheets, and interview guidelines. The data obtained were analyzed using the Mann-Whitney U test, t-test, and correlation test. The results showed that: (1) The improvement of the problem-solving abilities of students who received GeoGebra-assisted CPS learning was better than students who received conventional learning, and there was no difference in the problem-solving abilities of the superior early mathematical ability and low early mathematical ability groups; (2) The learning interest of students who receive GeoGebra-assisted CPS learning is better than students who receive conventional learning; (3) There is no correlation between problem-solving ability and student interest in learning. Creative problem-solving learning models assisted by GeoGebra applications can improve students' mathematical problem-solving skills and interest in learning.

Abstract

Indonesian students often struggle with solving math problems, especially when it comes to geometry, like problems involving triangles. However, previous studies have mostly focused on SQ3R in reading comprehension or general mathematics learning, leaving a gap in its application to geometry-based problem-solving. This study aims to examine the effectiveness of integrating the SQ3R strategy to enhance students’ mathematical problem-solving abilities on triangle materials. The research used a quantitative-qualitative method with a quasi-experimental design, and included two groups: an experimental group and a control group. The students were from a seventh-grade class at SMP Negeri 4 Cimahi, and they were divided into the two groups based on purposeful selection. Data was gathered through problem-solving tests, classroom observations, and other records. The results showed that the group that used SQ3R improved much more in their problem-solving skills compared to the group that didn’t use it. The SQ3R method helped students break down problems, come up with plans, do calculations, and check their answers in a better way. This study highlights the need for active literacy-based strategies in mathematics instruction and suggests future research to explore the broader application of SQ3R in other mathematical topics and grade levels. Abstrak Keterampilan siswa Indonesia dalam pemecahan masalah matematika masih dianggap rendah, terutama dalam pelajaran geometri seperti segitiga. Namun, penelitian sebelumnya sebagian besar berfokus pada penerapan SQ3R dalam keterampilan membaca atau pembelajaran matematika secara umum, sehingga masih terdapat kesenjangan dalam penerapannya pada pemecahan masalah berbasis geometri. Penelitian ini bertujuan untuk menguji efektivitas integrasi strategi SQ3R dalam meningkatkan kemampuan pemecahan masalah matematis siswa pada materi segitiga. Penelitian ini mengambil pendekatan kuantitatif-kualitatif dan menerapkan metode kuasi eksperimen berjenis Non-equivalent Control Group Design. Sampel terdiri dari 72 siswa kelas VII di SMP Negeri 4 Cimahi yang dibagi menjadi kelompok eksperimen dan kontrol, keduanya dipilih secara purposif. Alat penelitian terdiri dari tes penyelesaian masalah, pengamatan, dan dokumentasi. Temuan penelitian menunjukkan peningkatan yang signifikan dalam kemampuan pemecahan masalah siswa pada kelompok eksperimen dibandingkan dengan kelompok kontrol. Strategi SQ3R terbukti berhasil mendukung siswa dalam memahami permasalahan, merancang solusi, melakukan perhitungan, dan memeriksa hasil secara terstruktur. Penelitian ini menegaskan pentingnya penerapan strategi berbasis literasi aktif dalam pembelajaran matematika serta merekomendasikan penelitian lanjutan untuk mengeksplorasi penerapan SQ3R pada topik matematika dan jenjang pendidikan lainnya.

Abstract

Creativity is a crucial 21st-century skill, yet students' mathematical creativity remains relatively low. This research aims to develop mathematics learning materials based on the Pijar Sekolah Learning Management System (LMS) that are interactive, contextual, and problem-based to foster creativity by considering self-confidence. The Research and Development (R&D) method using the ADDIE model was employed. The sample consisted of two classes at a vocational school in Bandung. Data were collected via questionnaires, interviews, and observations, then analyzed using Aiken’s V, Cronbach’s Alpha, Two-Way ANOVA, and Pearson correlation. Results showed the materials are valid (Aiken’s V = 0.738) and reliable (Alpha = 0.945). Two-Way ANOVA revealed that the LMS method significantly improves creativity specifically for students with high self-confidence (p = 0.004), although it showed no significant difference for the overall group (p = 0.905). A significant positive correlation between self-confidence and creativity was found only in the experimental class (r = 0.478, p = 0.021). These findings emphasize that digital platforms optimize creativity when balanced with high student self-confidence.
