Abstract

Materi pecahan masih menjadi permasalahan bagi banyak siswa di sekolah dasar, khususnya yang melibatkan soal cerita matematika. Pada kenyataannya, sebagian besar siswa dapat menyelesaikan materi pecahan secara aritmatika, namun kesulitan jika diminta untuk menggambarkanya secara visual. Penelitian ini bertujuan untuk menganalisis kemampuan representasi visual siswa kelas V sekolah dasar dalam menyelesaikan masalah pecahan berbentuk soal cerita. Metode penelitian yang digunakan mengikuti kaidah penelitian kualitatif deskriptif dengan teknik pengumpulan data menggunakan tes dan wawancara. Sebanyak 23 siswa kelas V mengisi lembar tes kemampuan representasi visual yang kemudian dikelompokkan berdasarkan kategori kemampuan matematika. Dari 23 siswa, 6 orang dipilih untuk mewakili kategori kemampuan matematika untuk diwawancara. Hasil dari penelitian ini menunjukkan bahwa semua partisipan memiliki kemampuan representasi visual yang beragam. Siswa dengan kemampuan matematika tinggi mampu merepresentasikan konsep pecahan ke dalam bentuk gambar dengan tepat, namun tidak dengan siswa berkemampuan sedang yang kurang tepat dalam merepresentasikan pecahan ke dalam bentuk gambar. Selanjutnya, siswa dengan kemampuan matematika rendah tidak mampu menyelesaikan masalah pecahan menggunakan gambar dengan tepat. Hasil penelitian ini berimplikasi pada pentingnya mengajarkan dan memberikan pemahaman terkait dengan materi pecahan yang tidak hanya berpusat pada kemampuan aritmatika saja, namun terlebih penting lagi menekankan pengajaran konsep pecahan menggunakan representasi yang mengedepankan sisi visual.

Abstract

School closures due to the COVID-19 pandemic has resulted in learning loss in primary students, so a diagnosis of the students' numeracy skills is urgently needed at the beginning of learning to adapt learning to students' average ability levels (teaching at the right levels). This study aims to develop a module that can assist and become a reference for teachers in schools in diagnosing and mapping students' numeracy abilities at the beginning of learning. This research was carried out following the procedures for research and development (R&D). The developed module was validated by two experts (media and material experts) prior to implementation with the validation results being in very good categories for each aspect of the material, layout, and graphics. The results of the study based on the teacher's response questionnaire indicated that the module developed is very helpful for the teachers in mapping students' numeracy abilities at the beginning of learning after the COVID-19 pandemic, and it provides an alternative follow-up to the results of students' numeracy assessments. Thus, the developed module is suitable for use as a reference in conducting assessments regarding early primary school students’ numeracy skills.

Abstract

Mathematics education is taught to students from the basic level with the aim of equipping them with various skills, such as logical, analytical, systematic, critical, and creative thinking abilities, as well as the ability to work together. One of the abilities that is measured is cognitive ability. Cognitive ability involves the thinking process in the form of generally recognizing depicted objects and can be expressed in ideas, responses, or values. This mathematics learning activity also certainly involves problems in solving mathematical story problems. The procedure for solving story problems certainly involves steps for resolution, namely by using problem-solving according to Polya's theory. This research aims to describe students' cognitive abilities in solving word problems based on Polya's theory. The research instrument used in this study was a test, confirmed through interviews. The research results show that students with moderate ability are unable to solve problems in the cognitive category of applying (calculating indicator) and creating (designing indicator) especially in the Polya stage of checking, because the checking process is not found in their answer sheets. Meanwhile, students with low ability also cannot solve problems in the applying cognitive category (calculating indicator) and creating cognitive category (designing indicator), and are unable to solve story problems using Polya's stages of planning, executing, and checking. Thus, it can be concluded that students' ability to solve LOTS and HOTS questions is still at a low level because they find it difficult to work on questions in the cognitive domains of applying and creating.

Abstract

Understanding the information on the problem presented in the form of pictures is not an easy task for preservice primary teachers to lead to errors. However, preservice primary teachers can also answer correctly if given a mathematical model directly. Preservice primary teachers’ errors can be determined using a process point of view in solving mathematical problems. In a qualitative context, this study describes and analyzes the mistakes of preservice primary teachers traced through errors in solving mathematical literacy problems. This research is qualitative research, where analysis is needed to broaden the understanding of the errors that occur when solving mathematical literacy problems. The results showed that preservice primary teachers experienced errors on each indicator in four types of errors when solving mathematical literacy problems. This research found one new type of error, namely carelessness, which is an error with different types of the four types of errors that exist. Further research can be carried out by designing strategies used to improve the ability of preservice primary teachers to solve mathematical literacy problems.
