Abstract

A crucial aspect in various disciplines is numeracy skills. The purpose of the study was to determine the difference in the average social-emotional competence and numeracy skills of students before and after the implementation of differentiated learning that integrated social-emotional competence. The research was conducted at SMP Negeri Satu Atap 1 Cimanggu, Cilacap. The sample in this study was selected using the saturated slicing technique involving 22 grade VIII students. The type of research is an experimental study that uses a pre-experimental design with a one-group pre-test post-test method. The data collection techniques used include observation, tests, and questionnaires. There are 20 questions in the questionnaire. Data analysis was carried out quantitatively using paired sample t-tests and descriptive statistics. Before conducting the analysis, a prerequisite test was carried out using a normality test to test the distribution of data. The results of the study showed that the numeracy skills had a significance value of 0.200 (>0.05) and the social-emotional competence had a significance value of 0.11 (>0.05) which showed that the data was normally distributed. The results of the analysis showed that the value of the t-test of numeracy was 49.423 (t-test > ttable), with a significance value (2-tailed) < 0.05 (0.00 < 0.05). For KSE, the statistical value of the t-test was 27.54 with a very small p-value (5.75×10⁻¹⁸) indicating that there is a significant difference in the average value of numeracy skills and KSE before and after the implementation of integrated differentiation learning KSE. Integrated differentiation learning KSE can be applied to improve numeracy skills. The results of this study can be used as a solution to overcome the low mathematical numeracy skills of students.

Abstract

Pembelajaran matematika sering dianggap sulit dan abstrak oleh peserta didik, sehingga diperlukan media yang mampu meningkatkan pengalaman belajar yang bermakna dan menarik. Penelitian ini bertujuan mengembangkan media e-komik berbasis etnomatematika guna meningkatkan kemampuan berpikir divergen dan self-efficacy siswa pada materi geometri kelas IV. Pendekatan yang digunakan adalah kuantitatif dengan metode preeksperimen melalui desain pretest-posttest satu kelompok eksperimen. Media e-komik diharapkan mampu meminimalisir kekurangan media cetak dan mengaitkan konsep matematika dengan kebudayaan lokal untuk memberikan konteks yang relevan. Hasil penelitian menunjukkan bahwa penggunaan media ini berkontribusi signifikan terhadap peningkatan pemahaman konsep, kemampuan berpikir kreatif, serta kepercayaan diri siswa dalam belajar matematika. Dengan demikian, media e-komik berbasis etnomatematika dapat menjadi alternatif inovatif dalam meningkatkan hasil belajar matematika peserta didik.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi strategi optimal dalam memanfaatkan teknologi digital guna meningkatkan mutu pembelajaran di SMP Negeri Satu Atap 1 Cimanggu. Penelitian dilaksanakan dengan menggunakan metode deskriptif kualitatif yang melibatkan kepala sekolah, wakil kepala sekolah, guru, siswa, komite sekolah, dan orang tua sebagai informan utama. Data dikumpulkan melalui observasi, wawancara, dan dokumentasi sebagai bentuk implementasi metode pengumpulan data yang komprehensif. Data yang diperoleh dianalisis menggunakan model analisis interaktif yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Validitas temuan diperkuat melalui triangulasi teknik  dan triangulasi sumber. Hasil penelitian menunjukkan bahwa pemanfaatan teknologi digital memberikan dampak positif terhadap efektivitas pembelajaran, peningkatan keterlibatan siswa, serta efisiensi manajemen data sekolah. Namun, tantangan seperti keterbatasan infrastruktur dan rendahnya literasi digital masih perlu mendapatkan perhatian. Secara keseluruhan, penelitian ini menegaskan pentingnya kepemimpinan, kolaborasi, dan penguatan kompetensi digital sebagai faktor kunci dalam keberhasilan program digitalisasi pendidikan.

Abstract

Mathematical critical thinking is increasingly recognized as a core competence for enabling students to interpret problems, evaluate procedures, justify conclusions, and make reasoned mathematical decisions. Yet, students’ difficulties in exponents and radicals often reflect not only procedural inaccuracy but also fragmented reasoning that remains insufficiently diagnosed in classroom-based mathematics assessment. This study aimed to diagnose junior high school students’ mathematical critical thinking ability in solving exponent and radical problems through three indicators: elementary clarification, inference, and strategies and tactics. A descriptive diagnostic mixed-method design was employed involving 23 Grade IX students at SMP Negeri Satu Atap 1 Cimanggu, Indonesia. Data were collected using essay-based mathematical critical thinking tasks and analyzed through descriptive statistics and qualitative interpretation of students’ written responses. The quantitative findings revealed a critically low level of mathematical critical thinking, with a mean score of 26.57, a standard deviation of 3.55, the highest score of 35, and the lowest score of 20. None of the students reached the very good, good, or moderate categories; 26.09% were classified as low, while 73.91% were classified as very low. Qualitative analysis showed that students could identify limited explicit information but struggled to evaluate solution completeness, construct evidence-based inferences, justify strategy efficiency, and interpret results contextually. These findings indicate that students’ weaknesses are structural within the reasoning process rather than merely computational. The study contributes a diagnostic perspective by shifting the analysis from achievement-based classification toward indicator-based mapping of mathematical reasoning weaknesses, offering a foundation for more reflective, conceptually grounded, and reasoning-oriented mathematics instruction.
