Abstract

Critical thinking is an essential skill that students must possess in order to face various academic challenges and the dynamic development of scientific knowledge. Among psychological factors, self-efficacy plays a significant role in students' mathematical critical thinking skills, enabling them to solve tasks or problems in specific situations. This study aims to examine the influence of self-efficacy on students’ mathematical critical thinking abilities. The research employed a quantitative approach with a correlational design to analyze and explore in depth how self-efficacy affects students’ mathematical critical thinking skills. The sample consisted of 25 students from SDN Harapan Mulya. Data analysis was conducted using simple linear regression to determine the extent to which students’ self-efficacy influences their mathematical critical thinking abilities. The results showed a positive and significant influence between self-efficacy and critical thinking skills (p < 0.05), with a coefficient of determination of 0.224. This indicates that students’ self-efficacy contributes 22.4% to the variation in their mathematical critical thinking abilities. Therefore, the conclusion of this study is that the higher the students’ self-efficacy, the higher their mathematical critical thinking skills, which means that self-efficacy significantly influences students’ mathematical critical thinking. These findings highlight the importance of strengthening self-efficacy through various learning approaches to enhance students’ mathematical critical thinking skills.

Abstract

The inability of primary school students to solve mathematical problems using multiple strategies, often rigidly adhering only to methods taught by the teacher, highlights a critical issue: a low level of Divergent Thinking. This study aims to investigate the effectiveness of the Problem-Based Learning (PBL) model utilizing Dienes Blocks in enhancing the Divergent Thinking skills of fourth-grade students in whole number operations. The research employed a quantitative One-Group Pretest-Posttest Design involving a sample of 30 students from a public elementary school in Cimahi City. The intervention was conducted over two meetings, focusing on guiding students through the PBL process to discover and articulate various methods for solving calculation problems. Data were collected using a six-item essay test designed to measure the students' fluency and flexibility in problem-solving strategies, a core indicator of Divergent Thinking. The findings indicate a significant improvement in students' Divergent Thinking ability after the implementation of the PBL model with Dienes Blocks. The increase in scores, analyzed using the N-Gain method, was categorized as moderate. This suggests that the combination of authentic problem contexts provided by PBL and the concrete manipulation offered by Dienes Blocks effectively enables students to break free from rote memorization and explore alternative problem-solving pathways. The study concludes that this integrated approach is an effective strategy for fostering cognitive flexibility and creativity in elementary mathematics education.

Abstract

Mathematics learning problems, especially on the Pythagorean theorem material, cannot be studied only from one side, but need to be seen comprehensively from various integrative learning studies. This study aims to provide an overview of the evaluation of learning Pythagorean theorem material from reputable studies. This research uses the Systematic Literature Review (SRL) method. A review was conducted of 13 relevant articles published in various reputable international journals in the period 2019 to 2024. The data analysis used was carried out with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Based on the results of the review, it was found that in the Pythagorean theorem material there are still many misconceptions of understanding, with implications for the ability of abstraction that is not optimal. The quality of teaching is influenced by teachers' motivational beliefs in teaching, technology integration can help increase learning motivation, streamline learning and students are happier with teachers who use learning media, and teacher motivation in applying technology has an important role. In the realm of learning innovation, problem-based learning with a realistic mathematics approach is proven to be valid and effective and encourages active students and positive responses to the Pythagorean theorem material. Evaluation instruments must be valid, reliable, well designed to be effective in optimizing the learning process and diagnosing learning difficulties.        Keywords: pythagorean theorem, learning evaluation, mathematics learning.DOI: http://dx.doi.org/10.23960/jpmipa/v25i2.pp847-863

Abstract

Perkembangan layanan kesehatan di Indonesia menunjukkan perkembangan cukup pesat, terutama sejak hadirnya program Jaminan Kesehatan Nasional (JKN) melalui BPJS Kesehatan yang kini mencakup lebih dari 96,8% penduduk. Cakupan yang hampir menyeluruh ini menciptakan dinamika baru dalam pasar layanan kesehatan dan memberikan ancaman yang cukup besar bagi klinik non-BPJS. Tanpa dukungan skema kapitasi, klinik non-BPJS harus mengandalkan kemampuan manajerial dan strategi internal untuk tetap bertahan serta mempertahankan jumlah pasien. Penelitian ini berupaya merumuskan strategi manajerial yang relevan bagi klinik non-BPJS agar mampu meningkatkan daya saingnya. Pendekatan yang digunakan bersifat deskriptif kualitatif melalui systematic literature review terhadap 20 sumber ilmiah berupa jurnal, buku, laporan industri, dan regulasi kesehatan. Proses analisis dilakukan dengan memanfaatkan teknik tematik, SWOT, dan Porter’s Five Forces untuk menangkap pola, peluang, serta tantangan yang memengaruhi kinerja klinik non-BPJS dalam industri kesehatan yang semakin kompetitif. Temuan penelitian memperlihatkan bahwa terdapat tiga strategi utama yang secara konsisten muncul dalam literatur. Pertama, diferensiasi layanan, terutama melalui penguatan Unique Selling Point (USP), pengembangan layanan premium, dan peningkatan pengalaman pasien. Kedua, efisiensi operasional, termasuk optimalisasi sumber daya manusia, pemanfaatan teknologi informasi kesehatan, serta pengendalian biaya operasional. Ketiga, kepatuhan terhadap regulasi, khususnya terkait standar akreditasi dan tata kelola klinik, yang menjadi dasar penting untuk membangun kepercayaan publik. Ketiga strategi tersebut, apabila diintegrasikan secara tepat, dapat membentuk model manajerial yang lebih adaptif sekaligus memperkuat posisi kompetitif klinik non-BPJS. Temuan ini diharapkan dapat memberikan kontribusi praktis bagi pengembangan manajemen layanan kesehatan, khususnya pada fasilitas yang beroperasi di luar skema BPJS.

Abstract

This research aims to determine the level of effectiveness of a model, namely discovery learning in mathematics learning, on students' mathematical understanding. This research had research subjects consisting of 18 class X SMA Budi Bakti 2 Cianjur students. Carried out using mixed methods, the instruments used were also created to measure quantitative as well as qualitative data. The data analysis used was hypothesis testing with a one-sample t test carried out on students' posttest scores. Apart from the t test, correlation and regression tests were also carried out on students' interest in learning and mathematical understanding. From the research conducted, the use of the discovery learning model is effective for application in mathematics learning in terms of mathematical understanding. The use of the discovery learning model has proven to be effective because students' mathematical understanding can exceed the KKM score. Interest in learning has a correlation with students' mathematical understanding, therefore interest in learning also has a regression towards mathematical understanding with a relatively high level of regression or a dominant influence.
