Kesalahan atau kesulitan belajar bisa menjadi sumber penting dalam pembelajaran. Terdapat beberapa jenis kesulitan belajar aljabar yang dialami siswa, yaitu: (a) kesalahan dalam memahami lambang ‘=’; (2) tendensi penggunaan prosedur aritmatika dan pengabaian variabel; (3) generalisasi; (4) abstraksi; dan (5) pemaknaan grafik. Dengan mengetahui jenis kesulitan belajar tersebut maka guru bisa merancang pembelajaran yang tepat. Lebih lanjut lagi, jika merujuk pada pendidikan matematika realistik, terdapat empat pandangan tentang belajar aljabar, yaitu: (1) aljabar sebagai aktivitas manusia (algebra as human activity); (2) aljabar sebagai aktivitas otak (algebra as brain activity); (3) aljabar sebagai aktivitas personal (algebra as personal activity); dan (4) aljabar sebagai aktivitas yang bermakna (algebra as meaningful activity). Kata kunci: kesulitan belajar aljabar, pembelajaran aljabar Errors or difficulties in learning could be an important source of learning. There are several types of students’ difficulties in learning algebra, namely: (1) Errors in understanding the symbol ‘=’; (2) Tendency to use arithmetic procedures and to ignore variables; (3) Generalization; (4) Abstraction; and (5) Graph interpretation. Teacher can design appropriate learning by identifying those students’ difficulties. Furthermore, there are four views about learning algebra referring to Realistic Mathematics Education: 1) algebra as human activity; (2) algebra as brain activity; (3) algebra as personal activity; (4) algebra as meaningful activity. Keywords: difficulties in learning algebra, algebra learning.

This study aims to analyze students' financial literacy abilities in terms of Bugisneese gender differences (oroane, makkunrai, calabai, and calalai) in solving math problems using a survey method of 309 XI graders of public senior high schools in Soppeng Regency, South Sulawesi Province. The data collection techniques were carried out using a financial literacy test and gender diversity questionnaires. The collected data were analyzed using ANOVA with the help of IBM SPSS Statistics 25 (trial version). The research results showed that there were differences in students' financial literacy abilities, especially between students with an oroane and makkunrai gender tendency. The financial literacy abilities of students who tend to gender with feminine roles (makkunrai and calabai) are better than students who tend to gender with masculine roles (oroane and calalai). These results construct the knowledge that differences in students' financial literacy abilities in terms of solving mathematics problems do not only occur in sex differences (binary gender roles) cases but also involve differences in non-binary gender roles. Therefore, gender role differences need to be considered in integrating learning mathematics with financial literacy.

Based on the study, computational thinking skills are influenced by science, technology, engineering and mathematics (STEM) skills, and there is a relationship between computational thinking skills and 21st-century skills. However, studies related to STEM attitudes, computational thinking and their impact on 21st-century skills are still very few and limited. The purpose of our study was to examine the impact of STEM attitudes and computational thinking on 21st-century. This research uses a quantitative approach. The participants of this study were students of a vocational school in Bantul Regency, Yogyakarta, Indonesia (N=290). Research data in STEM attitude, computational thinking, and 21st-century skills using a questionnaire. The data were analyzed using structural equation modeling techniques using the Smart PLS application. The results of the study obtained several findings, including: the model proposed in this study was valid; STEM attitude has a positive and significant effect on computational thinking; and computational thinking has a positive and significant effect on 21-st century skills. It can be argued that when STEM attitudes and computational thinking are more positive, 21-st century skills will improve. These findings have implications that curriculum development and STEM learning practices have to develop students’ computational thinking skills and 21st-century skills, especially in vocational schools.

Abstrak Pentingnya pembelajaran matematika tidak hanya mengembangkan kemampuan kognitif, tetapi juga afektif. Salah satu kemampuan afektif adalah disposisi matematis. Berbagai penelitian terkait disposisi matematis telah dilaksanakan peneliti di Indonesia. Oleh karena itu, tujuan dari penelitian ini adalah untuk mengkaji tren penelitian tentang disposisi matematis di Indonesia. Untuk mencapai tujuan tersebut, penelitian ini menggunakan Systematic Literature Review (SLR) yang mengkaji artikel ilmiah yang diterbitkan di jurnal pendidikan matematika yang terakreditasi oleh Science and Technology Index (SINTA2). Fokus utama penelitian adalah disposisi matematis. Penelitian ini mengungkapkan bahwa terdapat peningkatan jumlah publikasi artikel disposisi matematis siswa pada beberapa tahun. Pada publikasi tersebut, jenis penelitian yang paling banyak dilakukan adalah jenis penelitian kuantitatif. Mahasiswa S1 menjadi subjek penelitian yang paling banyak diteliti, sedangkan pendekatan Problem-Based Learning merupakan perlakuan atau model pembelajaran yang sering digunakan pada penelitian tersebut. Disposisi matematis paling banyak dikaitkan dengan aspek kemampuan kognitif HOTS. Analisis statistik deskriptif dan Uji-t adalah metode analisis data yang paling umum digunakan pada penelitian terkait disposisi matematis siswa. Berdasar pada temuan penelitian ini, beberapa rekomendasi diusulkan untuk penelitian mendatang yang mendukung disposisi matematis siswa antara lain meningkatkan keragaman jenis penelitian, dalam hal ini penelitian tidak terbatas pada penelitian jenis kuantitatif dan kualititatif, tetapi pada penelitian jenis lain yang belum atau jarang dilakukan yaitu Class Room Action Research (CAR) atau Research & Development (R&D) yang bertujuan untuk mengembangkan produk instruksional untuk meningkatkan kemampuan diposisi matematis.Abstract The importance of learning mathematics not only does go beyond the development of cognitive skills but also includes affective skills such as mathematical disposition. Several studies related to mathematical disposition have been conducted in Indonesia. Therefore, the aim of this study is to examine the research trend on mathematical disposition in Indonesia. This current study utilizes Systematic Literature Review (SLR) to review scientific articles published in mathematics education journals accredited by the Science and Technology Index (SINTA2). The focus was on mathematical disposition. The study found an increasing number of publications on students' mathematical disposition in recent years. The research revealed that quantitative research was the most common type of research. Undergraduate students were the most researched subjects and Problem-Based Learning was the treatment or learning model commonly used. Mathematical disposition was found to be most often associated with higher-order thinking skills (HOTS). Descriptive statistical analysis and t-test were the most used data analysis methods related to students' mathematical disposition. Based on the findings, several recommendations were proposed for future research to support students' mathematical disposition. These include increasing the diversity of research types, such as Classroom Action Research (CAR) or Research & Development (R&D) to improve mathematical disposition. Furthermore, future research should expand the scope of research by including other types of research that are rarely or not yet conducted, such as qualitative research. It is important to emphasize the significance of developing students' mathematical disposition as it can positively impact their future academic and career success.
