Abstract

Secondary school teachers need to have strong Mathematics Content Knowledge of chance and combination to teach effectively and help students understand the concepts. This study aims to describe the correlation between Mathematics Content Knowledge of senior and junior secondary school teachers. The research subjects in this study were 17 secondary school teachers consisting of senior and junior teachers. The results were analyzed using Pearson Correlation to describe the relationship between MCK and teacher tenure. Furthermore, two subjects (one senior teacher and one junior teacher) were taken to be interviewed and described the ability to solve chance and combination problems. The results showed that there was no correlation between MCK and teacher seniority. In the context of chance, r , while in the context of combination r . Based on the test and interview results, it was found that senior teachers performed the algorithm more sequentially and completely than junior teachers. This can be caused by the readiness of senior teachers in solving the problems given. The researcher hopes that there will be further research with more subjects and more varied materials.

Abstract

This article discusses the implementation of a workshop to strengthen the literacy Program Sekolah Penggerak (PSP) of primary school teachers in Sidoarjo. PSP is a government initiative to improve the quality of basic education and teacher participation is crucial to the success of the program. The workshop was designed to provide primary school teachers with an in-depth understanding of PSP concepts, objectives and implementation strategies. The method of organizing the workshop began with observation to determine the needs of the target in order to deepen the concept of literacy, then continued with the implementation of workshop activities which included presentations, group discussions, and practical simulations. Next, a questionnaire was administered to determine the interest, perceptions, attitudes and beliefs of participants towards improving literacy after participating in this activity. The evaluation results showed that the increase in teachers' understanding and involvement in PSP after attending the workshop was very positive. The results of the questionnaire on participants' perceptions of literacy improvement showed that 96% of participants had a positive perception of the workshop activities. The literacy strengthening workshop received a positive response from the participants. During the presentation of the material, participants followed with enthusiasm. This community service activity can improve teachers' understanding of literacy concepts and literacy misconceptions. participants were able to identify the potential and challenges in implementing PSP in their schools and develop strategies to improve the effectiveness of the program. With this workshop, it is hoped that the literacy of the PSP program can be improved, have a positive impact on learning at the primary level, and improve the quality of education in Sidoarjo.

Abstract

Learning mathematics on the topic of geometric transformations of lines still faces challenging because the concepts are abstract, making it difficult for students to understand changes in the position of object on the Cartesian coordinate plane. This study aimed to develop the Cartesian coordinate monopoly (MONIKA) teaching aid and to determine its quality in terms of validity, practicality, and effectiveness. This study employed a Research and Development (R&D) approach using the Hannafin and Peck model, which consists of three stages: needs assessment, design, and development and implementation. The research subjects were ninth-grade junior high school students. The research instruments included material and media expert validation sheets, and pretest and posttest instruments. Data were analyzed using percentage analysis for validity and practicality, as well as the Normalized Gain (N-Gain) test. The development process involved needs assessment, design, and development and implementation stages. The results showed that MONIKA obtained a validity score of 92.5% from the material expert 93.75% from the media expert, both categorized as “HighlyValid”. In terms of practicality, the product was categorized as “Highly Practical” based on student response questionnaires and learning implementation observations. Meanwhile, the effectiveness test yielded an average N-Gain score of 0,3746, which falls into the moderate category. Therefore, the MONIKA teaching aid is considered valid, practical, and effective, making it suitable for use as a mathematics teaching aid for learning geometric transformations of lines.

Abstract

Matematika memiliki peran penting dalam menyelesaikan persoalan sehari-hari, namun meotde ceramah yang dominan serinngkali kurang efektif dalam menumbuhkan pemahaman konsep dan motivasi belajar. Kurikulum 2013 menekankan pendekatan saintifik yang menuntut keterlibatan aktif peserta didik dalam proses belajarnya. Untuk menjawab tantangan tersebut, dikembangkan Clash of Cartesius (COC) yaitu sebuah alat peraga berbasis permainan pada materi transformasi titik. Penelitian ini bertujuan mendeskripsikan proses pengembangan COC serta menilai tingkat kevalidan, kepraktisan, dan keefektifannya. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan ADDIE yang meliputi tahap analisis, perancangan, pengembangan, implementasi, dan evaluasi. Subjek penelitian terdiri dari 30 peserta didik kelas VIII MTs Lana, dengan data yang diperoleh melalui wawancara, angket validasi ahli materi dan media, angket kepraktisan, observasi, angket motivasi, dan post-test. Hasil penelitian menunjukkan kevalidan materi memperoleh skor 87,50% dan kevalidan media 79,17% (kategori sangat valid), tingkat kepraktisan berdasarkan angket mendapatkan skor 83,08% serta observasi 81,49% (kategori sangat praktis), serta keefektifan berupa peningkatan motivasi 82,50% dan pemahaman konsep transformasi titik dengan rata-rata skor post-test 74,73 (signifikan di atas KKM). Temuan ini menegaskan bahwa COC merupakan media pembelajaran yang layak digunakan pada kegiatan pembelajaran serta memenuhi kriteria valid, praktis, dan efektif dalam meningkatkan motivasi dan pemahaman konsep transformasi titik. Namun, penelitian ini memiliki keterbatasan berupa jumlah sampel yang kecil, hanya dilakukan pada satu sekolah, serta tidak adanya kelompok kontrol maupun pretest. Oleh karena itu, penelitian selanjutnya disarankan untuk memperluas cakupan sampel, melibatkan kelompok kontrol, serta mengintegrasikan media dengan teknologi digital agar pengalaman belajar lebih komprehensif dan interaktif.
