STUDENTS' MATHEMATICAL LITERACY IN SOLVING PROBLEMS SYSTEM OF EQUATION OF THREE VARIABLES
No full textThe main focus in this study aims to analyze the mathematical literacy skills of students at senior high school in solving problems involving the system of linear equations of three variables. The researcher took a qualitative descriptive method. The research subjects were 34 students from class X8. Problem sheets and interviews were the main data collection methods in this study. Researchers reduced data, presented data, and drew conclusions to handle data using a triangulation approach. The indicators of mathematical literacy skills studied were 1) Communication; 2) Mathematization; 3) Strategies in problem solving; 4) Use of language and symbolic operations; formal and technical; 5) Reasoning and argumentation skills. The findings of this study revealed that only one indicator, the communication indicator, was mastered by students in the low mathematical literacy category. Three indicators, namely communication indicators, problem solving techniques and mathematical communication indicators, can be mastered by students with medium mathematical literacy. Students with high mathematical literacy were able to understand and use each sign correctly. Students at SMA Negeri 1 Slogohimo have an average percentage of low mathematical literacy ability of 21%, medium mathematical literacy ability of 18%, and high mathematical literacy ability of 61

Mathematical Representation Ability-Based Mathematical Contextual Problems of Sequences and Progression Material
No full textThis research objective is to analyze and explain the student’s capacity for mathematical representation based on mathematical contextual problems of arithmetic and geometric sequences and progression material. Students enrolled in SMA 1 Sukoharjo X.E10 were the subject of this research. The data collection process used interviews, tests, and documentation. This research used a descriptive research approach with a qualitative research type. Based on the findings of this research, students who have visual representation skills in mathematics are more likely to complete challenges that involve visuals, such as diagrams. Typically, mathematically symbolic representation-capable pupils utilize mathematical formulas and symbols to solve problems. Furthermore, students who have the ability to verbally represent mathematics have a tendency to encrypt problem-solving steps into words

model.This method has four different types of equilibrium point and will be investigated their
stability. Aedes aegypti population no longer exists in nature if the product of the rate of female
mosquitoes mating with a natural male mosquitoes, egg-laying rate, the rate of per capita number
of mosquitoes that grow into female mosquitoes, and the per capita rate of sterile mosquitoes
were released in the wild is less than the product of per capita death rate on stage before the adult
mosquito, mosquitoes per capita death rate at this stage and the adult female mosquitoes per
capita death rate of fertile females, per capita mortality rate of sterile male mosquitoes
Analisis Kemampuan Berpikir Kreatif Dalam Menyelesaikan Soal Matematika Berorientasi Pisa Konten Space And Shape Siswa Sekolah Menengah Pertama
No full textThe demand as a student is to be fluent of various abilities, one of which is the creative thinking ability. Creative thinking ability is a person's ability to create new ideas or ideas that are different, unique, and fresh and find their own way of solving problems. This study aims to determine the creative thinking ability of junior high school students in solving PISA-oriented math problems with space and shape content. This research uses descriptive qualitative method. The research subjects were six grade IX students at Muhammadiyah Junior High School, Surakarta Special Program. Data collection techniques using tests, interviews, and documentation. Data analysis using data reduction techniques, data presentation, and drawing conclusions. The results showed that students with low creative thinking ability did not do well in all indicators of creative thinking. While students with moderate creative thinking ability are good in indicators of creative thinking fluency and originality but are not good at indicators of flexibility and elaboration. Students with high creative thinking ability are good at all indicators of creative thinking
LEVEL KEMAMPUAN LITERASI MATEMATIS DALAM MENYELESAIKAN SOAL PISA DITINJAU DARI KECERDASAN LOGIS-MATEMATIS
No full textLiterasi matematika digambarkan oleh PISA sebagai kapasitas seseorang untuk merumuskan, menerapkan, dan menginterpretasikan matematika dalam berbagai situasi. Indonesia menduduki peringkat 61 dari negara-negara yang berpartisipasi dalam jajak pendapat pada tahun 2015, sedangkan pada tahun 2018 menduduki peringkat 70. Literasi matematika dan kecerdasan logis matematis saling berkaitan, siswa yang memiliki kecerdasan logis matematis akan mampu memahami masalah, memeriksa perhitungan, dan menggunakan penalaran dan abstraksi. Tujuan dari penelitian ini adalah untuk mendeskripsikan kemampuan literasi matematika siswa dalam hal tingkat kecerdasan logis matematis saat mereka menjawab soal PISA. Sebanyak 31 siswa dari kelas IX di SMP Negeri 1 Ngemplak menjadi subjek dalam penelitian ini, yang menggunakan metodologi kualitatif deskriptif. Seluruh data penelitian berasal dari wawancara siswa dan hasil tes kecerdasan logis matematis. Berdasarkan hasil penelitian, siswa dengan tingkat kecerdasan logis matematis tinggi mampu memenuhi persyaratan literasi matematis pada level 1 sampai 5, namun pada level 5 subjek masih mampu merumuskan dan mendeskripsikan hasil pekerjaannya, meskipun hasil akhirnya tidak tepat. Siswa dengan tingkat kecerdasan logis matematis sedang dan rendah mampu memenuhi indikator literasi matematis pada level 1 dan 3. Sedangkan pada level 2, 4 keduanya mampu memenuhi sebagian indikator literasi matematis serta pada level 5, dan 6 keduanya tidak mampu memenuhi seluruh indikator literasi matematis
Students' errors in solving HOTS mathematics problems based on newman's theory in view of learning independence
No full textMathematics plays a crucial role in developing students' cognitive skills, particularly at the junior high school level. One type of question commonly used in assessments is the Higher Order Thinking Skills (HOTS) question, which requires students to think critically, creatively, and analytically. However, many students still struggle with solving HOTS questions, often due to insufficient understanding of basic concepts, difficulties in applying those concepts, and low levels of self-directed learning. This study aims to provide an overview of student errors in solving HOTS problems based on Newman Theory in terms of learning independence. The method used in this research is a descriptive qualitative approach that worked on HOTS questions. Data were collected through tests, interviews, and self-directed learning questionnaires. The findings indicate that students' errors are largely related to challenges in concept mastery (K1), problem-solving strategies (K2), and a lack of independence in learning. Moreover, students with higher levels of self-directed learning performed better in solving HOTS questions. Based on these findings, it is recommended that educators implement teaching strategies that enhance students' self-directed learning, such as problem-solving activities and regular HOTS practice, to reduce errors in solving questions that require higher-level cognitive skills
