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.

The purpose of this study is to describe the mathematical communication skills of high school students in terms of guardian and idealist personality types. Subjects in this study were taken using a purposive random sampling technique of two students from class X senior high school in Bandar Lampung with different personality types, that is one student with guardian personality type and one student with a idealist personality type based on David Keirsey's personality dimensions, with personality type initial guardian (NAP) and initial idealist personality type (DBD). Mathematical communication skills are analyzed based on the following criteria : (1) the ability to write down what is known and asked about the questions; (2) the ability to write answers according to the purpose of the questions; (3) the ability to write down reasons for answering questions; (4) the ability to make mathematical terms and symbols; (5) the ability to make images that are relevant to the questions; (6) the ability to make conclusions in their own language. The results showed that subjects with guardian personality type were only able to master the five criteria of mathematical communication ability. The subject was unable to conclude with his own language. The results showed that subjects with idealist personality type were only able to master the five criteria of mathematical communication ability but the subject does not master the third criterian, the subject is unable to write down the reasons for answering the question.
