Abstract

This research aims to describe the understanding of mathematical concepts among 8th-grade students of SMP Negeri 15 Palu, specifically focusing on self-efficacy in the topic of linear equations. The type of research conducted is descriptive, utilizing a qualitative approach. The research method employed is the member-check method. The subjects selected for this study were 3 students from class VIII A of SMP Negeri 15 Palu, representing high, moderate, and low levels of self-efficacy as determined from the results of a self-efficacy questionnaire. They were subsequently administered a test on mathematical concept comprehension. The results of the research indicate that students with high self-efficacy demonstrate a very good understanding of mathematical concepts, mastering all concept comprehension indicators. Meanwhile, students with moderate self-efficacy master some indicators, and students with low self-efficacy only master the indicator of restating concepts. Thus, it can be concluded that subjects with high self-efficacy have a very good understanding of mathematical concepts, while subjects with moderate self-efficacy have a sufficiently good understanding, and those with low self-efficacy have a less adequate understanding of mathematical concepts. Keywords: Self Efficacy, Understanding of Mathematics Concepts

Abstract

The integration of ICT in learning is a component of 21st-century learning. Science and technology always develop rapidly from time to time.  The purpose of this study is to determine the knowledge and abilities of junior high school mathematics teachers in STEM learning. This research was also conducted to determine student knowledge related to STEM learning. This study used a mixed method. The results showed that most junior high school mathematics teachers in the Donggala district did not understand STEM/STEAM learning. The teacher has also not been able to apply the STEM/STEAM approach in the learning process. Therefore, it is hoped that mathematics teachers in the Donggala district can apply a STEAM-based approach combined with local wisdom in the Donggala district. And it is necessary to conduct training to improve teacher competencies related to STEM learning.

Abstract

This study aims to describe the errors made by students in solving problems on the material of circle equations based on Newman's Error Analysis (NEA) reviewing gender differences. This type of research is Descriptive research with a qualitative approach conducted in class XI MIA 2 Madrasah Aliyah Alkhairaat Kalangkangan. This study uses a test and interview method. The subjects of the study were 36 students of class XI MIA 2 who were given a classification test to obtain data on high-ability students. Choosing 2 informants as test and interview subjects, namely one female student with the most errors and one male student with the most errors. The results of this study are (1) reading error; 2) understanding the problem (comprehension error); 3) transformation error (transformation error); 4) process skills error; 5) error in writing the final answer (encoding error). Conclusion, the teacher's ability to identify errors made by students is very important to support the improvement of the learning process. The errors found include errors in reading questions, understanding problems, and mathematical process errors that include transformation errors, process skills, and writing final answers. Teachers need to pay more attention to the early stages of understanding questions and ensure that students can master the skill process correctly in order to reduce errors in calculations and writing final answers.

Abstract

This study aims to obtain a description of the mathematical representation of grade VIII students of SMPN Model Terpadu Madani in solving comparative story problems in terms of gender. This type of research is qualitative research with a qualitative descriptive approach. The subjects of the study were 2 students of SMPN Model Terpadu Madani, namely 1 male student and 1 female student. Data collection techniques used in this study include written tests and interviews. The results of the study showed that male and female students used indicators of mathematical representation, namely verbal representation, symbolic representation, and visual representation when solving comparative story problems. The verbal representation of male and female students was able to write down the steps to solve mathematical problems according to the indicators. The symbolic representation used by male and female students was able to write equations, mathematical models, mathematical operations and solve problems involving mathematical expressions. The conclusion is that male and female students generally use visual representation, but there are differences between male and female students. Male students only use pictures to clarify while female students use pictures and tables to clarify and facilitate problem solving.

This research aims to: 1) to obtain a description of the critical thinking ability of male students on the addition and subtraction of fractions 2) to obtain a description of the critical thinking ability of female students on the addition and subtraction of fractions. This type of research is descriptive using a qualitative approach. The subjects of this research were 2 students taken from 31 students of class VII A SMPN 9 Palu consisting of 1 male student with high mathematics ability and 1 female student with high mathematics ability. The results of this study showed that male and female subjects with high mathematics ability were able to fulfill the indicators of critical thinking ability by Facione (2015), namely: (1) can interpret the problem by identifying the information known and asked appropriately and able to interpret and understand the symbols contained in the problem, (2) connect between statements, questions and concepts by making mathematical modeling appropriately (3) determine and use the right strategy in the calculation process so as to find the right final solution, (4) able to draw conclusions from what is asked in the problem, and (5) have the awareness to re-examine the solution of the problem given by identifying errors in determining the strategy or in the calculation process and then being able to believe the answer. Penelitian ini bertujuan untuk memperoleh gambaran kemampuan berpikir kritis siswa laki-laki dan perempuan kelas VII A SMPN 9 Palu pada materi penjumlahan pecahan. Jenis penelitian ini adalah deskriptif dengan menggunakan pendekatan kualitatif. Subjek penelitian ini adalah 2 orang siswa yang diambil dari  31 siswa kelas VII A SMPN 9 Palu yang terdiri dari 1 orang siswa laki-laki berkemampuan matematika tinggi dan 1 orang siswa perempuan berkemampuan matematika tinggi. Hasil penelitian ini menunjukkan bahwa subjek laki-laki dan perempuan berkemampuan matematika tinggi mampu memenuhi indikator kemampuan berpikir kritis oleh Facione (2015), yaitu : (1) dapat menginterpretasi masalah dengan mengidentifikasi informasi yang diketahui dan ditanyakan dengan tepat serta mampu memaknai dan memahami simbol yang terdapat di soal, (2) menghubungkan antara pernyataan, pertanyaan dan konsep-konsep dengan membuat pemodelan matematika dengan tepat (3) menentukan dan menggunakan strategi yang tepat dalam proses perhitungan sehingga mampu menemukan solusi akhir yang tepat, (4) mampu menarik kesimpulan dari apa yang ditanyakan pada soal, dan (5) memiliki kesadaran untuk memeriksa kembali penyelesaian soal yang diberikan dengan mengidentifikasi kesalahan dalam menentukan strategi maupun pada proses perhitungan serta kemudian mampu meyakini jawabannya.
