Abstract

Abstrak. Penerimaan Peserta Didik Baru (PPDB) jalur zonasi merupakan salah satu strategi penting dalam pemerataan pendidikan di tingkat Sekolah Menengah Atas (SMA) di Indonesia. Kebijakan zonasi sekolah diyakini oleh pemerintah pusat dapat mewujudkan tantangan pemerataan kualitas pendidikan antar sekolah dan berkeadilan. Kabupaten Karanganyar menerapkan sistem ini untuk memastikan distribusi siswa berdasarkan kedekatan geografis antara tempat tinggal siswa dan sekolah. Namun, tantangan utama dalam pelaksanaan sistem zonasi adalah menentukan zona penerimaan yang optimal atau kekurangan kuota di sekolah-sekolah yang ada. Penelitian ini bertujuan untuk memodelkan dan menyelesaikan masalah zonasi pada peta PPDB SMA Negeri di Kabupaten Karanganyar menggunakan teori graf, khususnya pewarnaan graf. Algoritma Welch-Powell digunakan sebagai metode utama dalam pewarnaan graf ini. Hasil penelitian menunjukkan bahwa penerapan algoritma Welch-Powell mampu memetakan zonasi dengan warna minimum, sehingga dapat menjadi pertimbangan pemerintah daerah Kabupaten Karanganyar untuk meningkatkan pemerataan akses pendidikan di Kabupaten Karanganyar, terutama sebagai pertimbangan pembangunan Unit Sekolah Baru (USB) di wilayah-wilayah yang belum terdapat SMA Negeri.

Abstract

Literacy is the ability to understand, use, and interpret written information. One of the fundamental forms of literacy that is embedded in everyday life is numerical literacy, which refers to an individual's ability to apply numerical and arithmetic concepts in daily life and interpret quantitative information in their surroundings. This research aims to develop a valid, practical, and effective interactive storytelling-based learning video to enhance students' numerical literacy in geometry. To this end, Plomp’s research and development method was applied. The result showed that, firstly, the developed product was valid, with an average total validity score of 0.910 for content validation and 0.860 for media validation. Secondly, the product was deemed practical, with an average score of 91.67% based on teacher evaluation and 80.31% based on student evaluation. Thirdly, the product was considered effective in improving students' numerical literacy, with calculated values t obs = 11.5084 and critical region = {t, t>1.721}, as well as an average N-Gain score of 0.668, indicating a moderate level of improvement. These results indicate that the developed interactive storytelling-based learning video is valid, practical, and effective in enhancing students' numerical literacy in geometry.

Abstract

Background: This research is rooted in the exploration of a nuanced understanding of the effect of cognitive fragmentation on the conceptual grasp and problem-solving competencies among junior high school students.Aim: The principal aim of this investigation is to delve into the way cognitive fragmentation influences the conceptualization and problem-solving faculties of pupils aged 12-14, from varied academic milieus.Method: Employing a qualitative research blueprint, specifically phenomenological inquiry, the study probes into the subjective experiences and cognitions of the participants. Purposefully chosen for this research, the participants consist of junior high school students. The multi-faceted data collection approach includes task-centered, in-depth individual interviews with students and Focus Group Discussions with educators. The amassed data are then meticulously examined through thematic analysis.Result: Findings of the research reveal diverse manifestations of cognitive fragmentation among the learners. A phenomenon termed 'Pseudo construction' emerges when learners articulate correct responses without wholly comprehending the foundational concepts. 'Mis analogical construction' is recognized when incorrect analogies are deployed in problem-solving, culminating in fallacious solutions. 'Construction holes' are detected when learners exhibit inconsistent responses owing to an absence of alignment with scientific principles.Conclusion: In summation, this inquiry furnishes invaluable insights and evidence-supported strategies to foster efficacious learning and surmount cognitive impediments within the sphere of junior high school education. The conclusions drawn herein contribute to a broader understanding of cognitive dynamics in mathematics education, offering a fresh perspective on enhancing educational practices.

Abstract: "Marica": A Story-Based Motion-Cartoon Learning Media to Improve Students' Mathematical Representation Ability. This research is based on students' difficulties in presenting mathematical ideas and problem-solving, as well as their generally low positive attitudes towards mathematics. The researchers conducted an experimental study to examine the influence of MARICA media on students' mathematical representation abilities in the field of plane geometry. Additionally, the research aims to improve students’ mathematical representation based on various levels of mathematical logical intelligence using MARICA as a learning media. MARICA, an abbreviation for "Mari Membaca" integrates literacy concepts, engaging learning media, and story-telling. The quantitative descriptive research involved 56 first-grade elementary school students and measured both the cognitive (mathematical representation ability) and affective domains. Mathematical representation abilities were analyzed using two-way ANOVA, while affective domain data were analyzed descriptively. The results indicate a positive effect of MARICA on the mathematical representation abilities of first-grade students, with higher levels of mathematical logical intelligence correlating with better performance. Student responses to MARICA showed an increase in aspects of independence, critical attitudes, and creativity. It can be concluded that MARICA can be used to improve students’ mathematical representation and it works better for students who has good mathematical logical intelligence.Keywords: MARICA, mathematical representation, mathematical logical intelligence.DOI: http://dx.doi.org/10.23960/jpp.v14.i1.202424

Abstract

This study aims to develop an educational game as a learning media for mathematics at the elementary school level, particularly fractions.  Named Fraction Bakery, this game was developed as a response to complaints of students' and teachers' difficulty in learning and teaching fractions. This difficulty, if poorly addressed, may serve as an iceberg-like issue for their understanding of more advanced mathematic concepts. Number recognition, including fractions, is fundamental to learning mathematics. As a teacher, it is necessary to evaluate such learning difficulties and seek alternative interactive learning media their students can enjoy. For the purpose of the study, the research and development model proposed by Thiagarajan, consisting of Define, Design, Development, and Disseminate stages, was applied. This game was still in the development process by evaluating the media value using trial responses involving undergraduate students of mathematics education at Sebelas Maret University. Regarding the product's interface, 71% of respondents gave a high score, 57% gave a very high score to the game animation, 75% stated that the game would likely motivate users to learn (affective impact), and 57% stated that the materials delivered in the game are highly relevant to the competency

Abstract

One of the efforts to realize the vision and mission of the Government Islamic Junior High School 2 Surakarta (MTS N 2 Surakarta) to be one of the best schools at the national level is by participating in MYRES (Madrasah Young Researcher Super Camp), which conducted annually by the Indonesian Ministry of Religion. The school have participated in this event several times, but unfortunately, the result still needs improvement. After conducting a self-evaluation, there found some possible aspects that caused this situation. The lack of knowledge and experience in conducting research and writing academic articles of the teachers who became students’ supervisors indicated the main problem that caused this situation. Based on this situation, the Government Islamic Junior High School 2 Surakarta (MTS N 2 Surakarta), in collaboration with the Contemporary Mathematics Education Research Group of the Mathematics Education Department, Sebelas Maret University, has conducted intensive training for academic writing to be submitted to MYRES competition. This program was conducted for three months, from April to June 2022. This program comprised of some activities, a workshop on academic writing with a keynote from Yogyakarta State University, continued by intensive training conducted online and offline. Ten proposals resulted from this program, ten were submitted to MYRES, and two of the proposal finally can compete until the semifinal stage.
