Abstract

This study intended to investigate the creative thinking dispositions of students who can perform truth-seeking in solving mathematical problems. Truth-seeking behavior tends to show students' thinking disposition when they need to solve math problems. This behavior is very much needed by students in solving math problems, especially HOTS-type questions. This study is qualitative and employs a phenomenological approach. Three students from the Integrated Islamic Junior High School in Manokwari who sought the truth served as research subjects. Their answers on the answer sheets encouraged the determination of the subjects’ tendencies in truth-seeking and creative thinking. The results of thought-based and task-based interviews were then incorporated into the analysis to determine the creative thinking dispositions of truth-seeking students and the relationship between truth-seeking and creative thinking dispositions. The findings of this study indicate that all research subjects have diverse creative thinking dispositions; the more truth-seeker indicators that are met, the more creative thinking dispositions they possess. When solving mathematical problems, students tend to show how they think by how hard they try to find the truth. This result implies that it needs more research on the level of creative thinking disposition and how to increase students' true search.

Abstract

A well-constructed concept can aid pupils in comprehending any learning content. However, as seen by how students solve math problems, the construction process frequently encounters flaws. Students make various conceptual construction errors in online learning. This is a qualitative study conducted on Mathematics Education students of Universitas Papua. The purpose of this study was to determine the errors made by students in constructing concepts of functions during online learning. Five subjects were selected as the subjects. They were chosen by using the purposive sampling technique. The instrument was developed using material from online lectures on functions and has been validated by experts in the field of mathematics education. The findings indicated that there were five misconstruction concepts, i.e. pseudo construction, construction holes, mis-logical construction, mis-analogical construction, and misconstruction in problem-solving. For further research, to avoid unnecessary construction errors, it is recommended that before the learning process is carried out, the teacher should know the construction of students’ concepts, so that the process of students’ conceptual change in online learning can be known.

Abstract

The STEM-Robotics training at YPPK St. Thomas Aquino Junior High School in Kaimana, West Papua, was conducted to address teachers' low understanding of STEM and coding concepts and the suboptimal utilization of robotics facilities in schools. This program aims to improve teachers' understanding of STEM learning, coding competency, and attitudes toward the implementation of STEM-Coding. The program was implemented using a service-learning approach involving 28 teachers, 4 lecturers, and 3 students across five stages: needs identification, collaborative planning, practice-based implementation, critical reflection, and evaluation. Data were collected using a validated questionnaire and analyzed descriptively. The training results showed that teachers' understanding of STEM learning reached 52% in the moderate category and 48% in the high category. Teachers' understanding of coding reached 4% in the moderate category and 96% in the high category. In comparison, positive attitudes toward STEM-Coding learning reached 11% in the moderate category and 89% in the high category. Overall, all program success indicators were met, with more than 85% of teachers in the moderate-to-high category across all measured aspects. This program is effective in improving teacher competency and supporting the development of technology-based learning in areas with limited access to education.   Abstrak Pelatihan STEM-Robotics di SMP YPPK St. Thomas Aquino Kaimana, Papua Barat, dilaksanakan untuk mengatasi rendahnya pemahaman guru terhadap konsep STEM dan coding serta belum optimalnya pemanfaatan fasilitas robotik di sekolah. Program ini bertujuan untuk meningkatkan pemahaman guru tentang pembelajaran STEM, kompetensi coding, serta sikap terhadap implementasi STEM-Coding. Program dilaksanakan menggunakan pendekatan service learning yang melibatkan 28 guru, 4 dosen, dan 3 mahasiswa melalui lima tahapan, yaitu identifikasi kebutuhan, perencanaan kolaboratif, pelaksanaan berbasis praktik, refleksi kritis, dan evaluasi. Data dikumpulkan menggunakan kuesioner yang telah divalidasi dan dianalisis secara deskriptif. Hasil pelatihan menunjukkan bahwa pemahaman guru terhadap pembelajaran STEM mencapai 52% pada kategori sedang dan 48% pada kategori tinggi. Pemahaman guru terhadap coding mencapai 4% pada kategori sedang dan 96% pada kategori tinggi, sedangkan sikap positif terhadap pembelajaran STEM-Coding mencapai 11% pada kategori sedang dan 89% pada kategori tinggi. Secara keseluruhan, seluruh indikator keberhasilan program tercapai dengan lebih dari 85% guru berada pada kategori sedang hingga tinggi pada seluruh aspek yang diukur. Program ini efektif dalam meningkatkan kompetensi guru dan mendukung pengembangan pembelajaran berbasis teknologi di wilayah dengan keterbatasan akses pendidikan.

Abstract

The aim of this research is to find an alternative method in teaching mathematics, specially in circle topic for the 8th grader student in SMP N 14 Masni, that can improve the activity and student’s score in learning mathematics. This method is named commeth. This method is a combination of several learning methods, namely lecturer, outdoor study, demonstration, jigsaw, and tanya jawab. The datum of this research are analyzed by qualitative and quantitative method. Based on this research, the result showed that the student activity and the student’s score are increase along the learning process. The observation result of the student activity is 87,33%. It means that the students are active. The rate of the team work is 71,45. It means that the students are cooperative along the learning process. And the rate of students grade is 70,25 . It increased by 81,29%.

Abstract

Faktor afektif memiliki peran penting dalam keberhasilan pembelajaran matematika, namun kajian mengenai perbedaan gender pada aspek afektif masih menunjukkan hasil yang beragam. Penelitian ini bertujuan untuk menganalisis perbedaan gender dalam sikap terhadap matematika dan keuletan siswa. Penelitian menggunakan pendekatan kuantitatif dengan desain komparatif. Partisipan penelitian terdiri atas 120 siswa sekolah menengah pertama yang meliputi 60 siswa laki-laki dan 60 siswa perempuan. Data dikumpulkan menggunakan kuesioner sikap terhadap matematika dan keuletan yang telah memenuhi kriteria reliabilitas. Analisis data dilakukan melalui statistik deskriptif, uji normalitas Shapiro–Wilk, uji homogenitas Levene, dan independent samples t-test yang dilengkapi dengan ukuran efek Cohen’s d. Hasil penelitian menunjukkan bahwa siswa perempuan memiliki rata-rata skor sikap terhadap matematika dan keuletan yang sedikit lebih tinggi dibandingkan siswa laki-laki. Namun, tidak ditemukan perbedaan yang signifikan berdasarkan gender pada sikap terhadap matematika (p = 0,156) maupun keuletan (p = 0,187). Ukuran efek yang diperoleh juga berada pada kategori kecil. Temuan ini menunjukkan bahwa pengalaman afektif siswa dalam pembelajaran matematika cenderung relatif setara antara laki-laki dan perempuan. Oleh karena itu, pengembangan sikap positif dan keuletan perlu dilakukan secara inklusif tanpa membedakan gender.
