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.

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.

Abstract

This study aims to analyze students' perceptions of polyhedral constructions in terms of the Van Hiele theory of geometric thinking levels. The method used was descriptive research with a qualitative approach involving 26 ninth-grade students of SMP YAPIS Manokwari. Data were collected through tests and interviews. The tests were used to identify students' geometric thinking levels, while the interviews were conducted to explore students' perceptions of polyhedral constructions and to verify the test results. The data were analyzed through data reduction, data display, and conclusion drawing. The findings revealed that the students were at the visualization and analysis levels. Students at the visualization level tended to understand three-dimensional figures based on their visual appearance and observable shapes, whereas students at the analysis level were able to identify component solids and recognize several geometric properties used in problem solving. However, students at both levels still experienced difficulties in understanding the relationships among the parts of composite solids comprehensively. In conclusion, students' perceptions of polyhedral constructions develop in accordance with their geometric thinking levels. Therefore, geometry instruction should be adjusted to students' stages of thinking in order to support the development of a deeper understanding of geometric concepts.   Keywords: Geometry, Perception, Van Hiele Theory, Level of thinking

Abstract

This study aims to identify the types and causes of errors made by ninth-grade high-achieving students at SMP Yapis Manokwari in solving Systems of Linear Equations in Two Variables (SPLDV) problems based on Kastolan’s Theory. This research employed a descriptive qualitative approach. The research subjects were selected using a purposive sampling technique. Data were collected through written tests, semi-structured interviews, and documentation. The research instruments consisted of SPLDV test items and interview guidelines that had been validated by two Mathematics Education lecturers. The data were analyzed using the Miles and Huberman model, which includes data reduction, data display, and conclusion drawing. The results showed that high-achieving students still made conceptual, procedural, and technical errors in solving SPLDV problems. Conceptual errors were indicated by students’ inability to translate word problems into appropriate mathematical models. Procedural errors were reflected in the incorrect application of solution steps and the failure to complete the solution process. Technical errors were identified through mistakes in arithmetic operations. The causes of these errors included internal factors, such as a lack of conceptual understanding, weak computational skills, low accuracy, and forgetting solution procedures, as well as external factors, including poor study habits, lack of material review, teaching methods, and an unconducive learning environment. In conclusion, high-achieving students are still prone to making errors in solving SPLDV problems despite having good academic performance.   Keyword : Student Errors, SPLDV, Kastolan Theory, High-Achieving Students

Abstract

This research aims to analyze college students’ problem-solving abilities in solving non-routine promblems on the topic of limits. The type of research employed is descriptive qualitative. The research subjects were 15 mathematics students at Universitas Papua. From the total subjects, 4 students were selected using a purposive sampling technique as focus subjects for in depth interviews, consisting of two subjects from the moderate category and two subjects from the low category. Data analysis was conducted based on Polya’s problem-solving stages: understanding the problem, devising a plan, carrying out the plan, and looking back. The results indicated that the majority of students were in the low ability category (12 students) and the remaining were in the moderate category (3 students0. Moderate category subjects were able to understand the problem well and write down fairly systematic resolution steps, but lacked precision in final execution. Meanwhile, low category subjects showed effort to resolve the problems but faced major obstacles during the stages of devising and carrying out plans due to weak understanding of prerequisite concepts, and all subjects tended to neglect the looking-back stage. In conclusion, students’ problem-solving ability in solving non-routine limit problems is dominated by the low category. Learning approaches that habituate students to solving non-routine tasks and strengthening metacognitive aspects in re-evaluating their work are highly required.   Keywords: Problem-Solving Ability, Non-Routine Problems, Limit, Polya
