Various studies have shown that Indonesian students' literacy and numeracy skills still need to improve. One of the solutions to this problem is RME, and one of the components that influence this skill is teachers as a facilitator and their experiences. Thus, this research aims to refigure how students who receive Realistic Mathematics Education (RME) literacy and numeracy skills improve based on teacher's experiences. The research subjects are third, fourth, and fifth-grade students in elementary schools in Padang. Three schools were selected for each grade level and taught by three teachers with different experiences. The students were given literacy and numeracy problems before and after RME instruction. The answers were assessed and grouped to examine the student's literacy and numeracy achievement. The research results show that student's literacy and numeracy skills are better with RME learning. Student's literacy and numeracy skills are not influenced by teachers' experience.</p> Ahmad Fauzan, Yulyanti Harisman, Yerizon Yerizon, Suherman Suherman, Fridgo Tasman, Sahrun Nisa, Sumarwati Sumarwati, Hafizatunnisa Hafizatunnisa, Hamdani Syaputra Copyright (c) 2024 Infinity Journal https://creativecommons.org/licenses/by-sa/4.0 http://www.e-journal.stkipsiliwangi.ac.id/index.php/infinity/article/view/4614 Thu, 04 Apr 2024 00:00:00 +0000 Exploring contributing factors to PISA 2022 mathematics achievement: Insights from Indonesian teachers http://www.e-journal.stkipsiliwangi.ac.id/index.php/infinity/article/view/4598 <p>As an international benchmark, the Programme for International Student Assessment (PISA) 2022 evaluates the educational performance of 15-year-old students across various countries. It has been observed that the average mathematics score globally declined in 2022. Understanding the responses of mathematics teachers, as practitioners, to the PISA 2022 results is crucial for evaluating the reasons behind this decline in mathematics scores. This research aims to explore and understand the perspectives of Indonesian mathematics teachers on the factors contributing to the low PISA 2022 mathematics scores. This study employs a qualitative approach, with participants being randomly selected and includes interviews with 36 mathematics teachers in Indonesia. According to the statements provided by teachers, the decline in mathematics scores in the 2022 PISA, relative to the years 2018 and 2015, can be attributed to six primary factors: pandemic-related issues, curriculum, individual factors, resource limitations, student factors, and parental involvement. Subsequently, mathematics teachers provided several recommendations for the government, schools, and parents that might enhance student mathematics achievement. These recommendations include conducting more training, improving ICT facilities in schools, and strengthening parental knowledge about the importance of parental support. The findings of this study offer various recommendations that could be implemented by the government, schools, and mathematics teachers to improve student mathematical achievement and potentially increase PISA scores in 2025.</p> Tommy Tanu Wijaya, Wahyu Hidayat, Neni Hermita, Jesi Alexander Alim, Corrienna Abdul Talib Copyright (c) 2024 Infinity Journal https://creativecommons.org/licenses/by-sa/4.0 http://www.e-journal.stkipsiliwangi.ac.id/index.php/infinity/article/view/4598 Sun, 28 Jan 2024 00:00:00 +0000 Impact of "Donkey", "Snap" dan "King" (DSK) non-digital gamification cards on fourth-grade students' math performance in fractions http://www.e-journal.stkipsiliwangi.ac.id/index.php/infinity/article/view/4579 <p>This research investigates the impact of Non-digital Gamification (NDG) techniques on students' math achievement, focusing on Fractions. Utilizing a quasi-experimental design, the study involved 100 primary school students in Perak. Two groups were formed: the control group, which followed traditional teaching methods, and the experimental group, which experienced NDG learning approaches. The findings indicate that students using NDG perform better in math (fractions) assessments compared to those using conventional methods. This study provides empirical evidence supporting the efficacy of NDG in teaching Fractions. The results underscore the potential for educators to innovate and enhance gamification tools, particularly in mathematics, contributing to educational advancements aligned with the goals of the Malaysian Ministry of Education.</p> Mohd Afifi Bahurudin Setambah, Mazlini Adnan, Syaza Hazwani Zaini, Mujiasih Mujiasih, Riyan Hidayat, Muhammad Alhaji Ibrahim, Hayato Hanazono Copyright (c) 2024 Infinity Journal https://creativecommons.org/licenses/by-sa/4.0 http://www.e-journal.stkipsiliwangi.ac.id/index.php/infinity/article/view/4579 Wed, 31 Jan 2024 00:00:00 +0000 The development of realistic mathematics education-based student worksheets to enhance higher-order thinking skills and mathematical ability http://www.e-journal.stkipsiliwangi.ac.id/index.php/infinity/article/view/4506 <p>This study aims to provide educational resources in the form of worksheets based on Realistic Mathematics Education (RME) principles and focus on the topic of equal fractions. The main criteria for these resources are validity, feasibility, and effectiveness. The development methodology employed in this study is the ADDIE model, which encompasses the Analysis, Design, Development, Implementation, and Evaluation stages. The participants of this study consisted of 14 pupils enrolled in class IV at SDM Alam Surakarta. The assessment tools employed consisted of assessments on student learning outcomes about equivalent fractions and supplementary materials in the form of questionnaires, interview guides, and observation sheets. The examination of the data reveals that the learning tools have achieved a high level of validity, falling inside the extremely valid category, with an average score of 4.26. The feasibility test for the LKS, conducted by the assisting instructor, yielded an average score of 4.4. The pupils' performance on the LKS assessment yielded an average score of 4.89, placing them in the "very feasible" category. The classical student learning outcomes achieved a completeness of 85.71%, as evidenced by an average score of 80.35. Notably, 12 students attained a complete score. There is a noticeable upward trend in student engagement during each learning session. The findings from the data analysis conducted on instructors' competencies in managing RME-based learning revealed an average score of 92, indicating a high level of proficiency. Students who were qualitatively integrated into the eligibility questionnaire also expressed positive responses. Therefore, learning tools based on Realistic Mathematics Education (RME) exhibit high validity, feasibility, and effectiveness in educational settings, as they have been empirically demonstrated to enhance students' mathematical proficiency.</p> Sri Sutarni, Sutama Sutama, Harun Joko Prayitno, Anam Sutopo, Pasttita Ayu Laksmiwati Copyright (c) 2024 Infinity Journal https://creativecommons.org/licenses/by-sa/4.0 http://www.e-journal.stkipsiliwangi.ac.id/index.php/infinity/article/view/4506 Sat, 16 Mar 2024 00:00:00 +0000 Fostering mathematical connections and habits of mind: A problem-based learning module for elementary education http://www.e-journal.stkipsiliwangi.ac.id/index.php/infinity/article/view/4492 <p>Previous research has highlighted the challenges of improving students' mathematical skills, particularly in connecting mathematical concepts to everyday life and developing strong mathematical habits of mind. This research aims to integrate problem-based learning (PBL) into a mathematics module to enhance mathematical connection abilities and mathematical habits of mind. The ADDIE method was employed to achieve this goal, encompassing five stages: Analysis, Design, Development, Implementation, and Evaluation. The findings indicate that media, material, and language experts deemed the module highly suitable. Furthermore, the product was rated as highly practical based on teacher assessments, student responses, and observations during implementation. Effectiveness tests of the product, conducted through MANOVA, t-tests, and N-gain tests, revealed that the module is highly effective in enhancing students' mathematical connection abilities and moderately effective in improving their mathematical habits of mind. These findings underscore the importance of integrating digital learning technologies to increase the module's engagement and accessibility.</p> Yoppy Wahyu Purnomo, Rokhmatun Nabillah, Tian Abdul Aziz, Sri Adi Widodo Copyright (c) 2024 Infinity Journal https://creativecommons.org/licenses/by-sa/4.0 http://www.e-journal.stkipsiliwangi.ac.id/index.php/infinity/article/view/4492 Tue, 23 Apr 2024 00:00:00 +0000
