Abstract

This research uses the Polya problem-solving procedure to describe students' difficulty in problem-solving in the material about systems of linear equations in two variables. The method in this research is descriptive research. The subjects in this research were three students in Class VIII of SMP Negeri 6 Tondano. The data analysis techniques used are data presentation, data reduction and conclusion. The results of this research show that of the four stages of Polya problem solving, students who have the highest scores can fulfil all stages of Polya problem solving, students who have medium scores can fulfil three stages of Polya problem solving, and students who have high scores can fulfil two stages of Polya problem-solving.

Abstract

The current mathematical learning model demands a standardized process that can promote various learning abilities, one of which is the ability to understand mathematical concepts. After a survey was conducted in one of the schools in the Motoling sub-district, namely SMA Negeri 1 Motoling, it turned out that a problem was found during the covid-19 pandemic, namely the lack of understanding of students' mathematical concepts in matrix material which can be seen from the results of student tests on matrix material, it is suspected that this problem is caused by learning models that are less precise and varied to be used in this pandemic period because students tend to learn online and offline, so a learning model is needed in this case. Based on this, experimental research was conducted to determine the differences in students' mathematical concept understanding abilities between classes taught using the flipped classroom model and classes taught using traditional learning models. The selected research subjects were 2 homogeneous classes, with the number of students in the experimental class being 30 people and the number of students in the control class being 30 people. The results showed that the average ability to understand mathematical concepts of students who were taught using the flipped classroom model was 88.3 while students who were taught using the traditional model were 66.07. Based on the results of testing the research hypothesis using the t-test, it can be concluded that the ability to understand students' mathematical concepts in the matrix material of students who are taught using the flipped classroom learning model is more than students who are taught using the traditional (conventional) model.

Abstract

Mathematics is often seen as a deductive science and is not related to social aspects. Even though mathematics grows and develops from socio-cultural practices that occur in society. This is the basis for the development of ethnomathematics concepts. The ethnomathematics concepts in the Bolaang Mongondow community are very diverse. This study aims to describe the implementation of ethnomathematics in learning mathematics at SMP Negeri 7 Kotamobagu, especially in the use of regional languages ​​and symbols of the Bolaang Mongondow Kabela Box Craft. The data obtained is in the form of qualitative data while the sources are obtained from interviews, observation, and documentation from informants (teachers, students and craftsmen). The main instrument is the researcher, while the supporting instruments used are interview guides and documentation. The results showed that the regional language and the symbols of the Bolaang Mongondow Kabela Box craft really helped teachers and students in the process of learning mathematics at SMP Negeri 7 Kotamobagu.

Abstract

Tujuan penelitian ini adalah untuk menganalisis apakah terdapat kesalahan baru yang muncul dengan menggunakan aplikasi Nvivo. Subjek dalam penelitian ini adalah 6 orang siswa dari kelas VII-A SMP Garuda Manado yang dipilih berdasarkan hasil tes tertulis dengan materi pecahan. Dari hasil tes tersebut maka di pilih 6 subjek dengan penglasifikasian berdasarkan tingkat nilai siswa yaitu nilai tertinggi, nilai sedang, dan nilai terendah. Setelah itu dilakukan wawancara kepada ke 6 siswa ini dan hasil dari wawancara tersebut akan dimasukan pada aplikasi Nvivo untuk dianalisis. Kesimpulan dari penelitian ini adalah kegunaan aplikasi nvivo yang sangat membantu dalam menganalisis kesalahan siswa meskipun kesalahan siswa yang terjadi dalam penelitian ini sama dengan jenis kesalahan siswa menurut Newman.
