This study aimed to analyze and describe the eleventh-grade senior high school students' mathematical communication skills on linear program material in terms of concrete and abstract sequential thinking styles. This study employed a qualitative descriptive approach with the case study method. The sampling technique used was the purposive sampling technique. The mathematical communication skills test and thinking style questionnaires were employed as the data collecting technique. The analysis revealed that subjects in the AS category could make generalizations based on good reasoning in the written text aspect. On the other hand, subjects in the CS category were having a hard time constructing abstract assumptions. In the drawing aspect, subjects in the AS category showed good theories and concept understanding. In contrast, subjects in the CS category were only able to apply some of the information to draw graphs. In mathematical expressions, subjects in the AS category could process the information implied by the problem to make mathematical models correctly. Meanwhile, subjects in the CS category needed additional information or direction to understand the information to avoid mistakes.

The Subject

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.

The purpose of this study was to analyze and explore the effectiveness of constructivism approaches in improving mathematical communication skills of junior high school students in the city of Paser. The experimental quasi method was used in this study to test the hypothesis of the study. The sample of the study at three junior high schools in Paser City, representing high, medium and low school students.. The instruments used in this study were pre-post test, pre-post questionnaires, and observation. The data were analyzed using independent sample t-tests, paired sample tests, annova tests, and descriptive analysis. The findings of pre-post test and pre-post questionnaire analysis using t-test showed that there were significant differences in group mathematical communication skills using constructivism approach compared to groups using conventional approaches at all achievement levels of high school students (high, simple and low). Based on the observation, it is found that high achievement school students have good mathematical communication skills in mathematical communication, these are identified in many aspects and observation indicators achieved by students during learning.

This study aims to find out between students with high, medium, and low self-esteem in term of better mathematical communication. This type of research is quantitative research. The data analysis technique used was one-way variance analysis with inequivalent cells. The collection of students' mathematical communication data was obtained from the score of mathematical communication tests, and the data of self-esteem was collected through questionnaires. The subjects of this study were the eighth-grade junior high school students in Ponorogo with the high, medium and low schools categories. The results of this study indicate that students with high self-esteem possess better mathematical communication skills compared to students with moderate self-esteem and students with low self-esteem. Students with low self-esteem are having the same level of mathematical communication skills as students with moderate self-esteem.

Communication Ability

The ability of mathematical communication is the skill to communicate mathematics that is learned and the skill of using mathematics as a communication tool (mathematical language). Mathematical communication skills are very necessary in learning. Without mathematical communication skills, a person will not be able to deliver statements according to their desire. This qualitative descriptive study aims to describe the level of mathematical communication ability of junior high school students in solving open ended problems with the topic of functional graphs. The method of collecting data through written tests and interviews. Written tests were given to 115 8th grade students of junior high schools in Surabaya, followed by interviews of one student at each level of mathematical communication ability. The results showed 51 people (44%) were at fourth level, 27 people (24%) at third level, 23 people (20%) at second level, and 14 people (12%) at first level. Students at fourth level and third level are equally able to use mathematical language that was accurate and effective, and appropriate in providing the strategies. But it was different in giving the arguments. Students at second level can not provide logical arguments, the mathematical language used was less effective and accurate, and the strategies used were precise but incomplete. Students at first level did not provide the right strategies because the lack of information which contained in the story, did not provide responses more to the stories they have been written, and did not demonstrate the ability to use mathematical language that was  accurate and effective.

This study aims to determine the effect of GeoGebra software on junior high school students' mathematical communication skills. The method used is the quasi-experimental method. This research was conducted at Pasundan Rongga Middle School. With class VIII A as an experimental class with 28 students and class VIII C as a control class with 28 students. This study uses instruments that have been tested and declared valid and reliable. The instrument was adjusted to the indicator of mathematical communication skills with the number of questions tested as many as 5 questions to obtain pretest and posttest data in both the experimental class and the control class. Data testing is done using normalized n-gain formula so that the n-gain data obtained is processed using the SPSS 20 application to perform parametric statistical tests. The results showed that the mathematical communication skills of students who learned using GeoGebra software were better than students who learned without using GeoGebra software.

Student Resilience

The purposes of this study are to identify the level of communication skills and mathematical resilience of junior high school students and to find out their mistakes in finishing communication-based questions. The method used in this study is descriptive quantitative method. This study is conducted in an Islamic school namely MTs Al Basyariyah located in Bandung, Indonesia. Performing as the respondents of this study are 36 students of class IX-B. To collect the data, this study employs a communication-based question diagnostic test and a questionnaire on student resilience. The results of the study show that (1) most of the students find it difficult to do question number one whose indicator is written text; (2) students’ skill on doing communication-based questions is still low; and (3) there is not significant correlation between students’ communication skills and their resilience. To cope with these phenomena, it is recommended that teachers use learning strategies that are able to enhance students’ conceptual understanding so that their communication skills can be achieved.
