Abstract

Hasil Ujian Nasional (UN) SMA pada mata pelajaran matematika di tahun 2018 mengalami penurunan yang sangat signifikan yaitu 4,67% dibandingkan dengan hasil UN di 2 tahun sebelumnya. Penelitian ini bertujuan untuk mendeskripsikan pemahaman siswa ditinjau dari teori APOS (Aksi, Proses, Objek, dan Skema) untuk mengetahui penyebab turunnya hasil UN dengan letak pemahaman siswa. Jenis penelitian menggunakan deskriptif dengan pendekatan kualitatif dilaksanakan di kelas X MIPA-5 MAN Kota Palangkaraya pada tahun ajaran 2018/2019 dengan subjek penelitian 23 siswa dan diperoleh 3 siswa sebagai wakil subjek yang memenuhi kriteria pemilihan subjek. Urutan analisis data dimulai dari subjek berkemampuan sedang 2 siswa dan berkemampuan tinggi 1 siswa ditinjau dari teori APOS dan dilanjutkan dengan memetakan ke salah satu level dari triad perkembangan skema. Hasil penelitian menunjukkan bahwa subjek dengan kemampuan sedang (S18) hanya berada pada tahap Aksi, jika dipetakan pada teori triad perkembangan skema hasilnya subjek tidak masuk level manapun dari triad. Subjek dengan kemampuan sedang (S16) berada pada tahap aksi dan proses, jika dipetakan pada teori triad perkembangan skema hasilnya subjek berada di level intra (level 0). Subjek dengan kemampuan tinggi (S03) berada pada tahap aksi, proses, dan objek jika dipetakan pada teori triad perkembangan skema hasilnya subjek berada di level inter (level 1).

Abstract

The bibliography/reference is the last part in the preparation of a scientific paper. The function of the bibliography is to provide further information to the readers that the author's work is the result of various sources. Writing a bibliography on the completion of student thesis in the MIPA Education environment of FKIP University of Palangkaraya still makes many mistakes, including several authors' names that are not listed in the bibliography because the preparation has not been automatic / still uses the manual method. This activity will be routinely carried out every semester and several supporting activities, namely making learning media and avoiding plagiarism. The purpose of this activity is for students to get used to it and one day it will be realized that all the results of the student's thesis are required to be submitted to a journal. To achieve this goal, supporting programs are needed every semester. The selected students are all batches of 2019 to 2021 who will prepare thesis and proposal reports. The output of this activity is that 85 students have been skilled in compiling a bibliography and applying it in a thesis, as the first step in helping students to submit their thesis results to an accredited journal.

PkM activities last for 3 months with a total of 7 learning meetings with a total number of students varying from 27 – 35 students each week. Each meeting is filled with mathematics learning that is appropriate to the context of daily life on number operations; distance, speed, time; social arithmetic; and the volume of the space. Learning about local culture is also provided by introducing each district in Central Kalimantan. The good response given by the LPKA and the assisted students who felt the benefits of the PkM program stated that this program was truly called Devotion because the LPKA felt helped in fulfilling the learning materials and the assisted students also felt happy taking part in the learning.

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

Students in teacher education programs often experience difficulties in understanding statistical concepts due to their abstract nature and limited connection to real-world contexts. Nevertheless, statistics serves as a fundamental foundation for developing quantitative thinking skills in science education. This study aimed to develop the KIMATIKA Student Worksheet (Lembar Kerja Mahasiswa/LKM), which integrates mathematics and chemistry concepts in the Educational Statistics course to enhance students’ quantitative understanding. The study employed a Research and Development (R&D) method by adapting the ADDIE model and was conducted up to the development stage. The results of expert judgment validation indicated that the KIMATIKA worksheet demonstrated a very high level of feasibility. The material experts’ evaluation yielded an average score of 4.74 with an ideality percentage of 94.71% (Very Good), while the media experts’ evaluation resulted in an average score of 4.81 with an ideality percentage of 96.25% (Very Good). In addition, students’ evaluations produced an overall average score of 4.58 with an ideality percentage of 91.51%. These findings indicate that the KIMATIKA worksheet is substantively sound, well-structured in its presentation, linguistically appropriate, and visually effective, and it received very positive responses from students in its implementation.

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.
