This research aims to describe the forms of student misconceptions and the factors that cause misconceptions experienced by students in solving linear inequality problems with one variable containing absolute values in class X SMA Muhammadiyah 1 Pontianak. The subjects of this research were students of class X IPA 3 SMA Muhammadiyah 1 Pontianak, totaling 25 students. The research uses descriptive method as the research method. Case study is a form of research used. The results of the research revealed that the research subjects experienced five forms of misconception, namely notation misconceptions experienced by 1 student or by 4%, generalizing misconceptions experienced by 3 students or by 12%, misconceptions of the application of rules experienced by 6 students or by 24%, calculation misconceptions experienced by 2 students or by 8%, and specialization misconceptions experienced by 3 students or 12%. The misconceptions experienced by these students are caused by wrong intuition and incomplete reasoning, where students' intuitive thoughts that arise spontaneously when solving problems are still wrong and students' reasoning or logic is still wrong in drawing conclusions and being too broad in generalizing. Keywords: Misconceptions, Two-Tier Diagnostic Test, One Variable Linear Inequality Problem with Absolute Values

This study's objective is to ascertain whether A connection exists between students' math learning results on the subject include linear equations with three elements and their level of self-efficacy. The study used a sample of 20 students, which was carried out in September 2022. Correlation approaches were employed in a survey as the study methodology. Data were gathered using student math learning outcomes and self-efficacy instruments. The instrument's reliability and validity have been assessed., making it both valid and dependable. The answers of the self-efficacy questionnaire and the findings of the description were found to be regularly distributed using Lilliefors' prerequisite testing of normality. If the information is evenly distribute, a linearity and significance test is obtained that the results of the self-efficacy questionnaire and the descriptive question test are significant and linear. The correlation of the correlation moments obtained from rxy = 0.790 is used to test the hypothesis. It can be inferred from the findings of this investigation that the material of three-variable linear equation has a self-efficacy and the link between learning of mathematical results of a student.

The research purpose is to analyze the misconceptions by using the certainty of response index modified in trigonometric equations at class XI State Senior High School 9 Pontianak. that Research method used in this research was a case study. The subjects in this research were seven students of class XI IPA 1 and IPA 2 of State Senior High School 9 Pontianak. The instruments used in this research were diagnostic tests and interview guidelines. From the result of the study, obtained 8 out of 32 students had computation misconceptions, 9 out of 32 students had generalized misconceptions, 1 out of 32 students had specialization misconceptions, and 1 out of 32 students had theoretical misconceptions. Misconceptions experienced are caused by students are students' associative thinking, incomplete reasoning, wrong intuition, stages of student cognitive development, and student abilities. Generalizing misconceptions are the most common misconceptions experienced by students, the cause of this misconception is wrong intuition and the stage of students' cognitive development.

Salah satu yang dapat mempengaruhi terbangunnya keterampilan berfikir kreatif adalah scientific attitudes seseorang. Tujuan penelitian ini adalah (a) Mendeskripsikan profil scientific attitudes mahasiswa Program Studi Pendidikan matematika, (b) Mendeskripsikan kemampuan berpikir kreatif mahasiswa Program Studi Pendidikan matematika, (c) Menguji keterkaitan antara scientific attitudes dan kemampuan berpikir kreatif mahasiswa. Aspek kelancaran, aspek keaslian dan aspek kerincian termasuk kategori tinggi. Sedangkan aspek keluwesan termasuk pada kategori sedang. Bentuk penelitian menggunakan mixed methods dengan status sepadan yaitu menggunakan pendekatan deskriptif kualitatif dan pendekatan kuantitatif. Sedangkan sampel penelitian adalah mahasiswa yang tidak mengulang pada mata kuliah penilaian proses dan hasil pembelajaran matematika tahun ajaran 2022/2023. Pengambilan sampel menggunakan teknik klaster random sampling. Pengujian hipotesis penelitian dengan menggunakan analisis korelasi Kendall Tau. Hasil pengujian hipotesis menunjukkan bahwa terdapat keterkaitan yang erat antara scientific attitudes dengan kemampuan berfikir kreatif mahasiswa pada perkuliahan penilaian proses dan hasil belajar matematika. One that can affect the development of creative thinking skills is a person's scientific attitude. The aims of this study were (a) to describe the scientific attitude profile of students in the Mathematics Education Study Program, (b) to describe the creative thinking skills of students in the Mathematics Education Study Program, (c) to test the relationship between scientific attitudes and students' creative thinking skills. Aspects of fluency, aspects of creativity, and aspects of fact are included in the high category. In comparison, the aspect of flexibility is included in the medium category. This form of research uses mixed methods with commensurate status, namely using a qualitative descriptive approach and a quantitative approach. Meanwhile, the research sample was students who did not repeat the mathematics learning process and results in the 2022/2023 school year assessment course. Sampling using cluster random sampling technique. Testing the research hypothesis using Kendall Tau correlation analysis. The results of hypothesis testing show a close relationship between scientific attitudes and students' creative thinking abilities in the process assessment lectures and mathematics learning outcomes.

This research aimed to describe mathematical communication skills, mathematical resilience, and the relationship between mathematical communication skills and mathematical resilience. This research used a quantitative approach with a correlation research design. The population in this study were students of grade XI SMA Negeri 2 Teluk Keramat and the sample was students of grade XI MIPA 2.The results showed that the mathematical communication skills students tend to have is the ability to express mathematical concepts by stating daily events in language or mathematical symbols (mathematical expression ability) which were able to be achieved by the students as much as 62%. Whereas for mathematical resilience that students tend to have is to have curiosity, reflect, research, and make use of various sources in mathematics learning, which contributed 38.7% and were able to be achieved by 16 students (76%). Furthermore, based on the results of the Pearson Product Moment correlation test, a significance value of 0.021 and a correlation value of 0.500 was obtained. So it can be concluded that there is a significant relationship between mathematical communication skills, mathematical resilience, and the strength of the correlation between the two variables is classified as moderate. Keywords: Correlation, Mathematical Communication Skills, Mathematical Resilience
