The Subject

Students' mathematical communication skills are still unsatisfactory, the average student error shows an error in expressing daily events in the language of mathematics. This is due to a lack of student understanding of the material that has been taught, and the level of students' creativity in recording important concepts contained in the content of the subject matter is still not satisfactory, student records tend to be still boring. The purpose of this study are: (1) to describe the implementation of mind mapping in the scientific approach to improve students' mathematical communication skills, and (2) describe the results of the assessment of mathematical communication skills that occur in students after learning is done with mind mapping in the scientific approach. The type of research that the author is doing is included in classroom action research (CAR). The author uses interview, observation, test and documentation methods. As for the analysis, the author uses descriptive qualitative analysis techniques, namely in the form of qualitative data and quantitative data that the author obtained during direct observation in the field. The research findings show that the application of mind mapping in the scientific approach can improve mathematical communication skills in students of Jambi City Vocational High School 9. (1) The process of implementing mind mapping with a scientific approach to improve students' mathematical communication skills can run smoothly as planned. The application of mind mapping has provided new experiences for students and teachers and provides several benefits, the benefits of mind mapping obtained include: students become the spirit of learning, students easily remember lessons and students gain drawing experience to find the relationship between one concept and another concept and the teacher easier to explain the subject matter to students; (2) on the assessment of students 'mathematical communication skills, from quantitative data the acquisition of scores on students' mathematical communication obtained a high enough value, namely in the first cycle the average value obtained was 75.87 or around 77.2%, in the second cycle there was an increase namely 80.1 or around 87.1%.Keywords: Mind Mapping, scientific approach, and mathematical communication skills

Descriptive Approach

As part of 21st-century skills, communication is an essential skill for students. Students' mathematical communication tends to below, one of which is influenced by students' self-confidence. For this reason, the purpose of this study is to describe the mathematical communication skills in solving circle problems based on students' self-confidence. Determining the subject using purposive sampling technique, namely from 36 students of class VIII SMP in Madiun, East Java, Indonesia, obtained two subjects with high self-confidence (SCT) and one subject with low self-confidence (SCR). A qualitative descriptive approach was used in this study. Tests and interviews were used as data collection techniques. Data were analyzed through reduction, presentation, and concluding. The results of this study include: SCT is capable while SCR is less able to meet the indicators of mathematical communication skills both in writing and orally at the stages of understanding problems, implementing plans, and checking back; and SCT can meet mathematical communication indicators both written and oral, while SCR is less able to meet written mathematical communication indicators but can verbally at the stage of planning completion. The level of self-confidence of students differentiates their mathematical communication skills in solving problems. Thus, a teacher needs to design an appropriate question to train students' mathematical communication skills with low self-confidence.
