Abstract

This study has a goal, namely to describe the attitudes of junior high school students towards learning Mathematics. Disclosure of students' attitudes in learning mathematics is based on low mathematics learning outcomes at the junior high school level in Siak and Rokan Hulu Regencies, Riau Province. The type of research used is evaluation. The sample for this research was obtained from some students who were in Siak and Rokan Hulu Regencies, Riau Province. By using a sampling technique in the form of random sampling and data collection techniques in the form of surveys. The instrument used in this study was a questionnaire, to measure junior high school students' attitudes towards learning mathematics. Before the instrument was used, the instrument in the form of a questionnaire was validated in terms of content and construct. In terms of content, validity analysis used the aiken formula while construct validity used second order CFA. Statistical analysis by calculating the average and standard deviation and consulting the assessment guide table to obtain an assessment of individual student attitudes. The evaluation results show that the attitude of SMP towards learning mathematics is in the category of good students. Keywords: Attitude analysis, mathematics learning, junior high school

Abstract

Penelitian ini bertujuan untuk menganalisis kesulitan yang dialami siswa dalam menyelesaikan soal-soal pada mata pelajaran statistika. Metode penelitian ini menggunakan penelitian kualitatif dengan pendekatan deskriptif kualitatif. Populasi dalam penelitian ini adalah seluruh siswa SMP di Kabupaten Pekanbaru dengan sampel yang digunakan adalah 30 siswa SMP Negeri 25 Pekanbaru kelas IX semester genap tahun ajaran 2023/2024. Teknik pengumpulan data dalam penelitian ini adalah metode dokumentasi berupa hasil tes siswa pada mata pelajaran statistika yang terdiri dari 3 soal yang berisi indikator yaitu: 1) Menentukan nilai rata-rata data, 2) Memecahkan masalah untuk menarik kesimpulan, 3) menganalisis suatu data dalam bentuk diagram, yang selanjutnya akan diperbaiki dan dianalisis. Hasil dan pembahasan penelitian ini menunjukkan bahwa banyak siswa yang masih mengalami kesulitan dalam menyelesaikan soal-soal pada mata pelajaran statistika. Salah satu cara untuk mengatasi kesulitan tersebut adalah dengan lebih menekankan pada pemahaman dasar materi prasyarat dan materi utama yang dipelajari guna memberikan pemahaman mendalam terhadap konsep-konsep penting yang mendasari pemahaman siswa terhadap materi statistika.

Abstract

The purpose of this bibliometric analysis is to identify opportunities and trends in research related to mathematical problem-solving abilities on the topic of functions. This study uses a bibliometric method by collecting data from articles published between 2015 and 2024 through Google Scholar using the Publish or Perish software, with a total of 1,000 journal articles. Bibliometrics is used to provide a structural overview of a particular research era, containing the necessary information to analyze publications in fields relevant to the researcher’s focus. The findings of this study show that from 2015 to 2024, there were 994 articles related to mathematical problem-solving abilities on the topic of functions. The highest number of publications occurred in 2020, with a total of 177 publications, while the lowest was in 2024, with only 21 publications, based on analysis using the VOSviewer software. Variables related to mathematical problem-solving abilities on the topic of functions that present opportunities and novelty for future research include critical thinking ability, high school, mathematical problem solving, PBL (problem-based learning), development, grade VIII, analysis, and learning. These variables have not been widely explored by other researchers, indicating the potential for innovation and further development by future researchers.
