This study aims to describe students' written mathematical communication skills in open-ended problems based on their mathematical abilities. This research was conducted at grade VII-A of SMPN 1 Pamekasan. This research uses descriptive qualitative research. The instruments used were the Mathematical Ability Test (MAT), Written Mathematical Communication Skills Test (WMCST) on open-ended problems, and Interview Guidelines. The results showed that subjects with high and moderate mathematical ability were able to meet three indicators of written mathematical communication skills, namely being able to express mathematical ideas through writing, demonstrate and convey visually; able to understand, interpret and evaluate mathematical ideas in writing, as well as in other visual forms; and able to use mathematical notations in the structure to write down ideas and relationships with situation models in writing. Meanwhile, subjects with low mathematics ability can fulfill 2 out of 3 indicators of written mathematical communication skills, namely being able to express mathematical ideas through writing, demonstrate and convey visually; unable to understand, interpret and evaluate mathematical ideas in writing or other visual forms; and able to use mathematical notations in the structure to write ideas and relationships with situation models.

This research aimed to describe the thinking process of students in solving the system of linear equations based on Polya stages. This study was a descriptive qualitative research involving six Year 10 students who are selected based on the teacher's advice and the initial mathematical ability categories, namely: (1) Students with low initial mathematics ability, (2) Students with moderate initial mathematics ability, and ( 3) students with high initial mathematics ability categories. The results indicated that students with low initial mathematical ability category were only able to solve the two-variable linear equation system problems. Students in the medium category of initial mathematics ability and students in the category of high initial mathematics ability were able to solve the problem in the form of a system of linear equations of two variables and a system of three-variable linear equations. However, students found it challenging to solve problems with complicated or unusual words or languages.

Communication is one of the important things in the learning process because there will be social interactions that can make learning more lively. Through communication, students can understand and interpret understanding of mathematical problems, not only calculation problems but also mathematical problems in everyday life. This research aims to describe students' communication skills in solving mathematical literacy problems based on mathematical abilities. This research is qualitative descriptive research. The subjects in this research were 27 students of class VIII in one of SMP Swasta in Sidoarjo. Subjects were given a mathematics ability test to categorize the subject's mathematical abilities into high, medium, and low-levels. The research data were obtained from the results of mathematics literacy tests and interviews conducted by 3 selected subjects. The results showed that 1) students with high mathematical abilities have a medium category of communication skills because students can fulfill the indicators of expression, interpretation, use of notations/symbols, and evaluation with correct answers without complete reasons, 2) students with medium mathematical abilities have a medium category of communication skills because students can fulfill the expression and interpretation indicators with correct answers along with correct and clear reasons, fulfill the indicators of using notations/symbols with correct answers without complete reasons, but students do not fulfill the evaluation indicators, and 3) students with low mathematical abilities have a very low category of communication skills because students can fulfill the expression and interpretation indicators with wrong answers but there is a reason, fulfill the indicators of using notations/symbols with correct answers but no reason, but students do not fulfill the evaluation indicators.
