In a classroom, students are challenged to think and reason about mathematics. Therefore, mathematical communication skills are an essential feature as students express the result of their thinking orally and in writing. Based on observations, this skill is still not well-mastered by VIII grade students SMPN 9 Sungai Penuh. The solution is expected to be achieved by implementing the RME approach. This research objective is to describe the development and compare whether the mathematical communication skills of students who are instructed by the RME are better than direct learning. This is a quasi-experimental and descriptive research with a Nonequivalent Posttest-Only Control Group Design. The saturated sampling was used to select class VIII B as the experimental group and as the descriptive subject, while class VIII A was selected as the control group. There was an improvement in these skills based on the quiz for each indicator, except for the indicator of explaining mathematical ideas, situations, and relationships in writing using pictures, graphs, and algebra. The posttest used t-test analysis, it was found that the mathematical communication skills of the students who were instructed by using the RME were better than direct learning. Consequently, The RME effects on mathematical communication skills.Keywords – Mathematical Communication Skills, Realistic Mathematics Education, Direct Learning.

Integral learning is particularly challenging for students, primarily due to misconceptions predominantly caused by students' lack of understanding about functions, limits, and derivatives. Therefore, this research aims to investigate students’ thinking processes when solving double integral using Action, Process, Object, and Schema (APOS) theory, with a focus on past errors. In order to achieve the objective, a descriptive qualitative method was adopted. Data was collected from tests, interviews, and relevant documentation, and tested for validity using triangulation methods. The obtained results showed that high-ability students understood APOS stages in solving double integral. However, at the object stage, a lack of thoroughness in simplifying algebra led to misunderstandings. Medium-Ability Student (MS) was observed to successfully reach APOS stages when solving double integral using polar coordinates. Low-Ability Student (LS), on the other hand, showed inadequate understanding at the process stage, as evidenced by the failure to correctly draw the area and set integral boundaries. During the course of this investigation, process errors were found to be commonly associated with the calculations of double integral. In order to address these issues, Genetic Decomposition (GD) should be designed for other calculus topics, and error classification expanded to enhance the effectiveness of lectures.

First-order Ordinary Differential Equation (ODE) has many applications in physics, engineering, biology, economics, and ecology. Therefore, mastering the concepts and methods of solving ODE is essential for students to be able to apply mathematics in solving real-world problems. However, the teaching of first-order ODE has not paid attention to practical applications, so that students have difficulty linking theory with real cases. This study aims to analyze the implementation of the SOLO taxonomy and Newman Error Analysis (NEA) in first-order ODE. The methodology used is a case study. The research subjects consisted of nine students of the mathematics department of FMIPA Universitas Negeri Padang. Data were collected through tests, interviews, and documentation. Then the data were analysed quantitatively and qualitatively. The results showed that there were five errors in solving first-order ODE made by students, namely Reading Errors (RE), Comprehension Errors (CE), Transformation Errors (TE), Process Skill Errors (PE), and Encoding Errors (EE). Some of the causes of these errors include students' low ability to read mathematical symbols, students' inaccuracy, not being able to use algorithms correctly, not mastering the concepts of algebra, differential, and integral, as well as not understanding in determining the systematic solution of the problem and not being accustomed to writing the final answer. This information can be used as a guideline for lecturers in designing strategies and lecture designs for first-order ODE.
