Abstract

The integration of Computational Thinking (CT) into mathematics learning has become a key demand in 21st-century education, as it plays an important role in developing logical, creative, and systematic thinking skills. However, in the context of Indonesian education, implementing CT still faces various challenges, particularly regarding teachers’ understanding and readiness to integrate it into the learning process. This study aims to explore teachers’ perspectives on CT-based mathematics learning, including their understanding, perceived relevance, readiness, and the challenges they face in its implementation at the junior high school level. This study offers a novel contribution by explicitly distinguishing between teachers’ conceptual understanding of CT and their pedagogical readiness to implement CT in mathematics learning, a gap that has been insufficiently explored in previous studies. The study employed a qualitative approach with an exploratory design. The research population consisted of junior high school mathematics teachers in Singaraja City, Indonesia. Eight teachers were selected as research participants using purposive sampling based on criteria such as teaching experience, involvement in CT-related or technology-based learning, and willingness to participate in the study. Data were collected through semi-structured interviews, classroom observations, and analysis of learning documents, then analyzed inductively through the stages of data reduction, data presentation, and conclusion drawing. The results showed that the teachers’ perspectives on CT-based mathematics learning are conceptually positive but still limited in practice. CT is considered relevant and potentially effective in strengthening mathematical thinking skills; however, its implementation requires systematic support. Based on these findings, the study recommends providing continuous, practice-oriented professional development programs for teachers, developing CT-based mathematics teaching resources, and stronger policy support to facilitate the effective integration of CT into junior high school mathematics learning. The study's implications highlight the importance of strategies to strengthen teachers’ capacity.

Abstract

Kemampuan pemecahan masalah matematis merupakan salah satu kompetensi penting yang harus dimiliki peserta didik dalam pembelajaran matematika. Namun, dalam proses pembelajaran di sekolah, masih terbatas bahan ajar yang mampu melatih kemampuan tersebut secara optimal, khususnya yang berbasis konsep pembelajaran mendalam. Penelitian ini bertujuan untuk mengembangkan Lembar Kegiatan Peserta Didik (E-LKPD) berbasis konsep pembelajaran mendalam pada materi trigonometri kelas X SMA. Pengembangan E-LKPD menggunakan model ADDIE dengan berbantuan aplikasi Heyzine. Uji validitas isi/materi dilakukan dengan uji pakar dan dianalisis menggunakan formula Aiken’s V, uji kelayakan dilakukan dengan angket penilaian LORI, uji efektivitas dilakukan dengan penilaian tes ketuntasan, dan uji kepraktisan dilakukan dengan angket User Experience Questionnaire (UEQ). Uji validitas isi/materi mendapatkan rata-rata nilai V sebesar 0,92 yang berada pada kriteria sangat tinggi. Selanjutnya, uji kelayakan media mendapatkan rata-rata nilai sebesar 4,63 yang dikategorikan sangat tinggi. Melalui uji coba yang dilakukan kepada 39 peserta didik, didapatkan hasil angket respon guru dan peserta didik pada aspek kejelasan dan aspek efisiensi kedalam kategori baik, sedangkan aspek daya tarik, aspek ketepatan, aspek stimulasi dan aspek kebaruan termasuk kedalam kategori unggul. Pada proses uji coba, didapatkan juga bahwa E-LKPD memiliki keefektifan sangat baik dengan persentase ketuntasan sebesar 85%. Hasil tersebut menunjukkan bahwa E-LKPD yang dikembangkan efektif dalam meningkatkan kemampuan pemecahan masalah matematis peserta didik pada materi trigonometri. Dengan demikian, E-LKPD berbasis konsep pembelajaran mendalam yang dikembangkan tidak hanya membantu peserta didik dalam memahami materi, tetapi juga melatih kemampuan berpikir kritis, analitis, dan sistematis dalam menyelesaikan permasalahan matematis.

Abstract

The development of the 21st century requires students to possess higher-order thinking skills, one of which is computational thinking, which plays a crucial role in systematic problem-solving. However, students’ computational thinking skills have not yet reached their optimal potential, highlighting the need to investigate factors that influence them. Logical-mathematical intelligence is considered one of these factors. This study aims to identify and characterize the correlation between logical-mathematical intelligence and computational thinking skills among junior high school students. The sample consisted of 29 ninth-grade students from SMP Satu Atap Negeri 3 Banjar, located in Buleleng, Bali. The research instruments included validated multiple-choice tests to measure logical-mathematical intelligence and essay tests to assess computational thinking skills. Data were analyzed using normality tests, linearity tests, and the Pearson Product-Moment correlation test. The prerequisite tests indicated that the data were normally distributed and exhibited a linear relationship. The results of hypothesis testing revealed a significant positive correlation between logical-mathematical intelligence and computational thinking skills, with a correlation coefficient of 0.781, which is categorized as strong. This finding indicates that students’ computational thinking skills are directly proportional to their level of logical-mathematical intelligence.

Abstract

This study aims to implement and measure the accuracy of the combined Analytical Hierarchy Process (AHP) and Simple Additive Weighting (SAW) methods in making decisions about providing social assistance in Purwoagung Village. This study is a type of applied research that focuses on solving real problems practically by utilizing data obtained from the village government. Data were collected through observation, interviews, questionnaires, and documentation studies to ensure the validity and completeness of the information. In its implementation, data were analyzed through the stages of data mining, criteria weighting using AHP, and alternative ranking using the SAW method. The results showed that of the six criteria used, the head of the family's occupation had the highest weight (0.453), followed by home ownership status, number of dependent children, savings ownership, cooking fuel, and type of house floor. The alternative with the highest preference value of 0.866 was determined as the main priority recipient, while the lowest alternative obtained a value of 0.325. Accuracy testing using a confusion matrix showed an accuracy level of the AHP-SAW method of 92.11%, indicating very good classification performance. These results prove that the AHP-SAW method is effective in determining the eligibility of social assistance recipients objectively, systematically, and efficiently. This study recommends further development with additional methods to improve the accuracy and use of the results of this study by the village in preparing policies for the distribution of social assistance that are more targeted, fair, and transparent. Keywords: social assistance, community, Purwoagung Village, AHP – SAW method.
