Abstract

Abstract This research aims to improve students' mathematical connection skills through the application of a Think Talk Write (TTW) type cooperative learning model on quadratic function materials. This research is a Class Action Research conducted in two cycles, each of which includes holding planning, implementing actions, observation and reflection. The subjects in this study are 23 students of class X/A of Noemuti State High School. The data collection technique used mathematical connection ability tests and observation sheets of learning activities. The results of the study showed that in the first cycle the average score of students was 72.09 with classical completeness of 60.86. After learning improvements were made in the second cycle, the average student score increased to 84.22 with classical completeness reaching 100%. The results of the study show that the Think Talk Write model is able to improve learning activities, concept understanding and students' ability to connect various mathematical concepts. Thus, the Think Talk Write cooperative learning model is effectively used to improve students' mathematical connection skills on quadratic function material.

Abstract

This study aimed to analyze students’ mathematical reasoning ability in solving problems on the topic of quadratic equations at SMP Negeri Bitefa. The research used a qualitative descriptive approach with 18 eighth-grade students as participants. Data were collected through tests of mathematical reasoning and follow-up interviews with three selected subjects representing high, medium, and low levels of reasoning ability. The results showed that students’ reasoning abilities varied across five indicators: (1) making initial conjectures and predictions based on problem context, (2) performing mathematical manipulations to find patterns and relationships, (3) constructing systematic mathematical arguments and proofs, (4) evaluating mathematical arguments for accuracy, and (5) integrating analysis results to draw logical conclusions. The findings revealed that students generally demonstrated moderate reasoning ability. The strongest performance appeared in the ability to draw conclusions (50.74%), while the weakest was in generating conjectures (44.81%). These results suggest the need for mathematics instruction that emphasizes inquiry-based and problem-solving learning strategies to improve reasoning competence.

Abstract

This study aims to develop a Case-Based Learning-based LKPD integrated with character education on SPLDV material. This study uses the ADDIE development model which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The research subjects were 31 ninth-grade students of SMPN Mubeli who were selected by purposive sampling. Product validity was assessed by material experts, media experts, and character education experts. The practicality of the LKPD was measured through teacher and student response questionnaires, while effectiveness was analyzed based on the results of the post-test and student character questionnaires. The results showed that the developed LKPD had a very high level of validity with an average score of 90%. The practicality level of the LKPD was in the very practical category with an average of 91.3%. Furthermore, the Student Worksheet (LKPD) proved effective in improving student learning outcomes, with an average post-test score of 81.71 and classical completion reaching 100%. The character questionnaire results also showed improvements in critical reasoning, honesty, and responsibility, all within the good category. Thus, the Case-Based Learning-based LKPD, integrated with character education based on the local context of NTT, is declared valid, practical, and effective for use in SPLDV learning.Keyword: Student Worksheet, Case Based Learning, Character Education, SPLDV

Abstract

This study aimed to develop a valid, practical, and effective student worksheet (LKS) for linear programming material based on the Missouri Mathematics Project (MMP) model with peer feedback. Using a Research and Development (R&D) design comprising definition, design, development, and dissemination stages, data were collected through validation sheets, questionnaires, and tests. The developed worksheet was assessed as valid by experts 80%, practical based on student and teacher responses 85%, and effective in improving learning outcomes. Effectiveness was indicated by 79% classical completeness and a significant improvement in Post test scores compared to Pre test results (p < 0.05 ). The findings show that the MMP-based worksheet with peer feedback meets the criteria for valid, practical, and effective learning tools.

Abstract

This study aims to develop student worksheets based on a metaphorical thinking approach with tutor feedback to improve students’ mathematical connection ability in the topic of systems of linear equations in two variables. This research employed a development design based on the ADDIE model, which consists of analysis, design, development, implementation, and evaluation stages. The instruments used in this study included validation sheets, student and teacher response questionnaires, and mathematical connection ability tests. The validity assessment showed that the developed student worksheets obtained an average validity score of 93.06%, categorized as highly valid. The practicality test, based on student and teacher responses, obtained an average score of 84.5%, categorized as highly practical. The effectiveness of the worksheets was determined based on predefined criteria, namely the average achievement of students’ mathematical connection ability, classical mastery, and the difference between pretest and posttest scores. The results showed that the average posttest score reached 68.83, with classical mastery of 83.33%. In addition, students’ average score increased from 21.08 in the pretest to 68.83 in the posttest, and the paired sample t-test showed a significant difference with a sig. value of 0.000 < 0.05. These findings indicate that student worksheets based on a metaphorical thinking approach with tutor feedback are valid, practical, and effective for improving students’ mathematical connection ability.

Abstract

Penelitian ini bertujuan mengkaji kembali peran gaya belajar dalam pendidikan tinggi melalui analisis hubungan antara gaya belajar dan hasil belajar matematika mahasiswa calon guru, mengingat temuan sebelumnya masih belum konsisten. Penelitian ini menggunakan pendekatan kuantitatif dengan desain korelasional yang melibatkan 63 mahasiswa Program Studi Pendidikan Matematika Fakultas Ilmu Pendidikan Universitas Timor yang memprogramkan mata kuliah Geometri Transformasi pada tahun akademik 2023/2024. Data dikumpulkan melalui angket gaya belajar yang diadaptasi dari instrumen yang telah teruji dan disebarkan menggunakan Google Form, serta tes hasil belajar matematika. Data dianalisis menggunakan statistik deskriptif, uji ANOVA, dan korelasi Pearson. Hasil penelitian menunjukkan bahwa gaya belajar mahasiswa didominasi oleh gaya belajar auditori (65,08%). Rata-rata hasil belajar mahasiswa sebesar 71,51. Hasil uji ANOVA menunjukkan bahwa gaya belajar berpengaruh signifikan terhadap hasil belajar mahasiswa (F = 11,919; p < 0,05). Analisis korelasi Pearson menunjukkan adanya hubungan positif dan signifikan antara gaya belajar dan hasil belajar mahasiswa dengan koefisien korelasi sebesar 0,404 yang termasuk kategori sedang. Temuan ini menunjukkan bahwa praktik pembelajaran dosen dan budaya belajar mahasiswa memengaruhi dominasi gaya belajar. Oleh karena itu, dosen perlu merancang pembelajaran yang variatif dan adaptif untuk meningkatkan hasil belajar matematika.
