Abstract

Konsep pecahan merupakan salah satu konsep dasar yang perlu dipahami agar kemampuan mempelajari materi yang lain tidak terhambat. Namun kemungkinan terjadinya miskonsepsi pada siswa ketika belajar pecahan sangat mungkin terjadi. Diperlukan upaya untuk meminimalisir peluang miskonsepsi tersebut. Game edukasi adalah salah satu media belajar yang dapat memberikan pengaruh bagi siswa untuk memahami konsep yang dipelajari. Penelitian ini bertujuan mengembangkan aplikasi game edukasi android Deck Card yang valid untuk membantu siswa SMP/MTs memahami konsep pecahan dengan model pengembangan PPE (Planning, Production, and Evaluation). Instrumen penelitian meliputi lembar penilaian produk untuk ahli materi dan ahli media yang dipeer-review terlebih dahulu oleh expert judgment. Berdasarkan hasil uji kevalidan produk oleh ahli materi diperoleh kriteria sangat baik dengan persentase 83,82%, sedangkan dari ahli media diperoleh kriteria baik dengan persentase 74,56%. Hasil tersebut menunjukkan bahwa game edukasi yang dikembangkan valid dan layak diujicobakan pada siswa.The concept of fractions is one of the basic concepts that need to be understood so that the ability to study other materials is not hampered. However, the possibility of misconceptions in students when learning fractions is very possible. Efforts are needed to minimize the opportunities for these misconceptions. Educational games are one of the learning media that can influence students to understand the concepts studied. This study aims to develop a valid Android Deck Card educational game application to help SMP/MTs students understand the concept of fractions with the PPE (Planning, Production, and Evaluation) development model. The research instruments include product assessment sheets for the material expert and media experts who are peer-reviewed by expert judgment. Based on the results of product validity tests by material experts, the criteria were very good with a percentage of 83.82%, while media experts obtained good criteria with a percentage of 74.56%. These results indicate that the educational game developed is valid and worthy to be tested on students.

Abstract

Ethnomathematics based learning is a solution for children to instill character values as well as foster a sense of love for local culture in the midst of technological advances. This study aim to conduct a literature review related to ethnomathematics, namely the relationship between mathematics and culture, especially in Javanese culture, one ofwhich is traditional games. The method used in this research is SLR (Systematic Literature Review). The data collection technique was carried out by documenting and reviewing five articles related to character values and ethnomathematics in the Ingkling traditional game published in the period 2017 to 2021 from the Googe Scholar database. The data analysis technique used is to identify, evaluate, and intepret all available in research. Based on the results of the study, it was found that there are ethnomathematics in the traditional game of Ingkling which has many roles, one of which can be used by junior high school students to understand the concept of opportunity. In addition, these traditional games also contain cultural values and character values in them.

Abstract

This study employs a qualitative descriptive approach to optimize mathematics instruction at SMA Negeri 8 Yogyakarta through lesson study, aligning with the school's vision of fostering Higher Order Thinking Skills (HOTS) and critical thinking. Conducted in Class X E7 during the 2024/2025 academic year, the research was implemented over two cycles, encompassing planning, implementation, and reflection phases. An expository teaching model combined with the drill method was utilized to enhance conceptual understanding and problem-solving skills. Findings indicate that lesson study facilitated structured instructional refinements, improving student engagement and mathematical proficiency. Summative assessment results showed that 60% of students met the mastery criteria, reflecting progress in instructional effectiveness. However, challenges remained, particularly in students' ability to interpret HOTS-based contextual problems and manage time effectively during problem-solving tasks. Adjustments in cycle II, including extended time allocation and structured sequencing of exercises, led to improved problem-solving accuracy but did not fully address all learning gaps. This study highlights the effectiveness of lesson study in integrating HOTS and fostering critical thinking in mathematics instruction. Future recommendations include strengthening conceptual foundations, diversifying contextual HOTS-based problems, and incorporating time management strategies to optimize instructional outcomes.
