Abstract

One of the courses have often difficult by pre service teacher in primary education is Geometry, evidently by learning outcome that are still low. Difficulties experienced by students led to an error occurred in solving problem in geometry. Errors that occur when students solve problems in geometry really need to be known, especially the type of error. One of procedure that can be used to reveal the student error is Newman procedure. This research employed a descriptive qualitative method that aimed to analyze the errors of pre service teacher in primary education when solve the problems in geometry.  Participants in this research were two students who have taken the courses of Geometry and meet the criteria which is experiencing a mathematical error. Data collection technique use a question sheet and interviews. Question sheet given in order to analyze student errors that appear. While the interviews were conducted to confirm the results of student work. The results showed that the four stages of the procedure of Newman Error Analyze that comprehension, transformation, process skill and encoding occur mathematical error, logical error and strategic error. Furthermore, as new findings in this research, the error experienced by the students at this stage of the procedure Newman can cause errors in the later stages.

Abstract

Terdapat banyak penelitian yang menunjukkan bahwa konflik kognitif yang terjadi dapat dimanfaatkan untuk membantu mahasiswa memahami materi dengan baik atau menerapkan konflik kognitif sebagai strategi dalam pembelajaran. Namun, masih sangat sedikit penelitian yang melihat konflik kognitif dalam menyelesaikan masalah khususnya pada mahasiswa PGSD. Oleh karena itu, perlu dilakukan penelitian tentang konflik kognitif mahasiswa PGSD dalam menyelesaikan masalah matematika. Penelitian ini merupakan penelitian deskriptif kualitatif, yaitu menganalisis dan mendeskripsikan peran dari strategi konflik kognitif pada proses penyelesaian masalah geometri. Penelitian ini dilaksanakan pada mahasiswa yang sedang memprogram mata kuliah Geometri. Hasil penelitian menunjukkan bahwa mahasiswa yang mengalami konflik kognitif terbantu dengan kondisi yang dialaminya. Peran konflik kognitif yang dialami mahasiswa berdampak positif. Konflik kognitif tersebut menjadikan mahasiswa lebih memahami masalah yang hendak diselesaikan.

Abstract

This study aims to explore the skills that students need to develop in order to utilize mathematical knowledge in solving numeracy problems. A descriptive qualitative approach was employed, utilizing test instruments and in-depth interviews for data collection. Twenty-one fifth-grade elementary students participated in the numeracy assessment, with three subjects—representing low, medium, and high numeracy proficiency—selected for detailed interviews. Findings reveal that only students with high numeracy competence demonstrated the ability to integrate number sense, an understanding of mathematical relationships, computational skills, and information interpretation to solve numeracy tasks successfully. Conversely, students with medium and low proficiency exhibited significant difficulties, particularly in comprehending problem contexts and accurately applying arithmetic operations. Therefore, numeracy learning strategies need to integrate the strengthening of mathematical literacy and the development of conceptual understanding.
