Abstract

The aim of this research is to describe the critical thinking abilities of class X SMA Negeri 2 Grabag students. The research method used was qualitative with a research focus on the subject of three class X-2 students at SMA Negeri 2 Grabag, who represented various levels of ability, namely high group students, medium group students and low group students. Data collected through a written test which includes critical thinking indicators in mathematics interviews. The research results showed that there were 23% of students in the high category, 63% of students in the medium category, and 14% of students in the low category. Students in the high group are able to master all indicators of critical thinking in statistics material. Students with moderate abilities show good abilities except for some deficiencies in interpretation and analysis. Students with low abilities tend to have limitations in data interpretation, inference and other critical thinking skills such as analysis, evaluation and inference. The implication of these findings is the need for learning strategies to improve students' critical thinking skills in understanding and applying statistical concepts.

Abstract

Pembelajaran matematika di sekolah masih cenderung bersifat abstrak sehingga peserta didik sering mengalami kesulitan dalam memahami konsep secara kontekstual. Di sisi lain, budaya lokal seperti Batik Ganasan khas Subang menyimpan berbagai unsur matematis yang berpotensi dimanfaatkan sebagai sumber belajar berbasis etnomatematika. Penelitian ini bertujuan untuk mengidentifikasi unsur-unsur etnomatematika pada motif Batik Ganasan serta menganalisis keterkaitannya dengan materi matematika sekolah. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan desain etnografi untuk mengeksplorasi konsep-konsep matematis yang terkandung dalam motif Batik Ganasan di Jawa Barat. Lokasi penelitian berada di sentra produksi Batik Ganasan Subang dengan subjek penelitian meliputi pengrajin batik dan perancang motif, serta objek berupa motif batik yang dikaji. Data dikumpulkan melalui observasi partisipatif, wawancara semi-terstruktur, dan dokumentasi. Analisis data menggunakan model Miles dan Huberman yang meliputi reduksi data, penyajian data, serta penarikan kesimpulan dan verifikasi. Keabsahan data dijaga melalui triangulasi sumber dan teknik serta validasi ahli di bidang etnomatematika. Hasil penelitian menunjukkan bahwa motif Batik Ganasan mengandung berbagai unsur etnomatematika, yaitu partisi bidang datar, bangun datar berbasis lengkung, simetri lipat, translasi, tessellation, dilatasi, rasio dan proporsi, pola periodik, kesebangunan, serta keseimbangan visual asimetris. Unsur-unsur tersebut tampak pada pembagian bidang kain, pengulangan motif nanas, bunga, daun, serta pola isen-isen yang tersusun secara teratur. Temuan juga menunjukkan adanya keterkaitan antara unsur etnomatematika tersebut dengan materi matematika sekolah, khususnya geometri bidang, transformasi geometri, simetri, pola pengubinan, kesebangunan, dan perbandingan pada jenjang SD dan SMP. Dengan demikian, Batik Ganasan berpotensi dijadikan sebagai sumber belajar kontekstual dalam pembelajaran matematika berbasis budaya lokal. Hasil penelitian ini diharapkan dapat menjadi referensi bagi guru dalam mengembangkan pembelajaran matematika yang lebih kontekstual, inovatif, dan bermakna bagi peserta didik.

Abstract

Most studies treat mathematics learning interest as a single composite construct linked to learning outcomes, without first testing whether its constituent indicators, namely enjoyment, attraction, attention, and engagement, are themselves statistically interrelated. This study addresses that gap by examining the strength of pairwise associations among these indicators and their overall concordance. A quantitative, cross-sectional correlational design was employed using data from 53 seventh-grade students at a junior high school in Yogyakarta, selected through simple random sampling. Because the Kolmogorov-Smirnov normality test indicated that three of the four indicators departed from normality, non-parametric tests were applied: Kendall's tau-b for pairwise correlation and Kendall's W for overall concordance. The results show that only three of six indicator pairs were significantly and fairly associated, enjoyment-attraction (τb = 0.463), attraction-attention (τb = 0.281), and attraction-engagement (τb = 0.258), while the remaining three pairs showed very weak, non-significant associations. Kendall's W of 0.264 (statistically significant) indicates that the four indicators exhibit real but modest overall concordance. These findings offer both methodological and practical contributions: aggregated interest scores may obscure heterogeneous student profiles, so diagnosis and instructional intervention should target specific indicators, with attraction serving as the most central connective dimension, rather than treating learning interest as a homogeneous construct.

Abstract

Yogyakarta's reputation as a cultural city, student city, and tourist destination does not exempt it from acts of criminality. The increasingly rampant phenomenon of klitih, particularly in the Yogyakarta area, is a transformation of a local term that originally had a positive meaning but has now shifted into a form of street violence committed by youths. This article aims to examine klitih within the context of social reality and connect it to the socialist utopian perspective of Edward Bellamy. Klitih is viewed as a reflection of social failure in educating and shaping the character of adolescents, triggered by weak family control, social environment, and educational institutions. Through a descriptive-qualitative approach and literature review, this article identifies the driving factors behind klitih, including adolescent identity crises, poor parenting patterns, character-deficient education, and negative environmental influences. Within Bellamy's conceptual framework, solutions to the klitih phenomenon must be based on social transformation to eliminate inequality, build solidarity, and strengthen social institutions such as families, schools, and communities. Preventive strategies can be implemented through schools by emphasizing character education, and through active roles of families, law enforcement, and communities that support the healthy and just development of adolescents. Thus, addressing klitih requires collaborative efforts from all parties so that its occurrence can be minimized, or even eliminated.

Abstract

The low numeracy skills of junior high school students remain a major challenge in Mathematics learning, particularly in plane figures material that requires conceptual understanding, procedural application, and integrated reasoning. This study aims to analyze the numeracy skills of seventh-grade students at SMPN 2 Kasihan using an open essay test. The approach in this study was a descriptive, quantitative design, with 120 students as the main participants. The instrument consisted of seven validated essay questions to measure aspects of mathematical understanding, application, and reasoning. Data were analyzed using descriptive statistics, including maximum, minimum, average, and standard deviation scores, as well as categorization of student achievement. The results showed a very significant variation in ability. Most students were in the low category, and only a few were in the very high category. The highest achievement was in understanding, while application and reasoning were still very low. These findings emphasize the need for innovative, problem-based, context-driven learning, supported by intensive remedial programs and peer tutoring, to comprehensively improve students' mathematical literacy and address the challenges of 21st-century national education.
