Abstract

Critical thinking is increasingly important with the existence of Artificial Intelligence (AI) especially for college students. AI is not yet fully accurate in solving mathematical problems, so critical thinking helps students analyze and evaluate its answers. This study aims to enhance students’ critical thinking using PBL (Problem-Based Learning) with ChatGPT and GeoGebra. This quasi-experimental study with the pretest-post-test non-equivalent group design involved 47 subjects, 24 in the experimental group and 23 in the control group. The average pre-test and post-test of experimental (47.96 and 62.13) and control (55.48 and 54.26) groups were significantly different. The ANCOVA results showed that PBL with ChatGPT and GeoGebra significantly enhanced students’ critical thinking. Tukey’s test result showed that the difference between the experimental and control group was 14.88 which indicated that students’ critical thinking in the experimental group was higher than the control group. Furthermore, the treatment did not affect identify indicator, but had a positive effect on justify, inference, clarify, and strategy decision indicators. This demonstrates that PBL assisted by ChatGPT and GeoGebra enhances students’ critical thinking. The research has the potential to support lecturers in enhancing students’ critical thinking and improving innovative learning models where AI can be used in education with proper guidance and implications.Berpikir kritis semakin penting dengan adanya kecerdasan buatan (AI) khususnya bagi mahasiswa. AI belum sepenuhnya akurat dalam menyelesaikan masalah matematika, sehingga berpikir kritis membantu mahasiswa menganalisis dan mengevaluasi jawabannya. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan PBL berbantuan ChatGPT dan GeoGebra dalam meningkatkan kemampuan berpikir kritis mahasiswa. Populasi penelitian ini adalah seluruh mahasiswa Program Studi Pendidikan Matematika pada semester 4. Sampel penelitian dipilih menggunakan teknik cluster sampling dengan penentuan kelas eksperimen dan kelas kontrol secara acak. Penelitian kuasi-eksperimen ini dengan desain pretest-post-test non-equivalent group melibatkan 47 subjek, 24 pada kelompok eksperimen dan 23 pada kelompok kontrol. Rata-rata pre-test dan post-test kelompok eksperimen (47,96 dan 62,13) dan kontrol (55,48 dan 54,26) berbeda secara signifikan. Hasil ANCOVA menunjukkan bahwa PBL dengan ChatGPT dan GeoGebra secara signifikan meningkatkan berpikir kritis mahasiswa. Hasil uji Tukey menunjukkan perbedaan antara kelompok eksperimen dan kontrol sebesar 14,88 yang mengindikasikan bahwa berpikir kritis mahasiswa pada kelompok eksperimen lebih tinggi dibandingkan kelompok kontrol. Selain itu, perlakuan tidak berpengaruh pada indikator identify, tetapi memberikan pengaruh positif pada indikator justify, inference, clarify, dan strategy decision. Hal ini menunjukkan bahwa PBL yang dibantu oleh ChatGPT dan GeoGebra meningkatkan berpikir kritis mahasiswa. Penelitian ini berpotensi mendukung dosen dalam meningkatkan berpikir kritis mahasiswa dan memperbaiki model pembelajaran inovatif di mana AI dapat digunakan dalam pendidikan dengan bimbingan dan implikasi yang tepat.

Abstract

This study investigates the effect of combining peer tutoring with a project-based learning (PjBL) model on the academic performance of students enrolled in an Educational Statistics course within an elementary teacher education program. A quasi-experimental design was employed with two intact classes (n = 42) from a state university in Indonesia. The experimental group received peer-assisted PjBL instruction, while the control group experienced conventional PjBL without peer tutors. Both groups followed the same syllabus, instructor, and assessment structure. Data were collected through standardized Midterm (UTS) and Final (UAS) exams validated by subject-matter experts. The findings revealed that students in the experimental group achieved significantly higher academic performance and demonstrated greater improvement from midterm to final exams compared to the control group, with a moderate effect size (Cohen’s d = 0.59). The integration of peer tutoring within project-based activities effectively reduced anxiety, encouraged collaboration, and deepened conceptual understanding of statistical principles. These results confirm that peer-supported, project-based instruction offers a practical and contextually relevant approach to improving statistical learning outcomes among pre-service teachers. The study underscores the importance of active, student-centered pedagogies in preparing future educators to navigate data-rich educational environments. Future research is recommended to examine the long-term retention, scalability, and adaptation of this model across different subjects and institutional settings.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a strategic role in the national economy, including in Kapuas Regency, Central Kalimantan, which is dominated by the culinary sector. However, most MSME owners have not yet obtained halal certification due to limited understanding, lack of access to information, and the perception that the certification process is complicated. This community service program aimed to improve MSME owners’ awareness, knowledge, and technical capacity in obtaining halal certification through the self-declare scheme. The service method employed a participatory and mentoring-based approach, implemented through structured stages consisting of preparation, implementation, and evaluation. The preparation stage involved coordination with local stakeholders, identification of MSME needs, and participant registration. The implementation stage consisted of material delivery using lectures and discussions to enhance awareness of the importance of halal certification, followed by hands-on technical assistance in using the official online halal certification system. Participants were also guided through a simple internal audit of production processes to ensure compliance with halal standards. The evaluation stage was conducted using questionnaires and direct observation to measure participants’ satisfaction, understanding, and ability to independently complete the halal certification registration process. A total of 37 culinary MSME participants successfully completed the halal certification registration through the self-declare scheme. Evaluation results indicated that the program was highly beneficial, with an average participant satisfaction rate exceeding 80%. Furthermore, the program increased MSME owners’ awareness of halal certification as a guarantee of product quality and a strategic tool for enhancing business competitiveness. Overall, this community service program successfully strengthened MSME capacity in utilizing digital-based halal certification systems and supported the development of a more competitive halal MSME ecosystem in Kapuas Regency.
