Mathematical communication and social skills of the students through learning assurance relevance interest assessment and satisfaction

The purpose of this research is to analyze mathematical communication skills and find patterns in thinking process of students in terms of social skills through learning Assurance Relevance Interest Assessment and Satisfaction (ARIAS). This research was conducted in Tasikmalaya city with 80 students as research subjects. The research method uses a sequential explanatory combination. Data was collected through tests of mathematical communication skills and social skills questionnaires. Data analysis techniques to test hypotheses using proportion tests. Based on the results of data analysis, it was concluded that mathematical communication skills of the students through ARIAS learning achieved ideal completeness. Subjects from very skilled groups, thinking processes in mathematical communication skills on each indicator written text, drawings, and mathematical expressions have written what is known and asked, equipped with images, the steps are clear, answer in 2 ways, but there are errors in so wrong calculations in the final result. Whereas subject from skilled groups, have not written in full what is known and asked, the stages are incomplete, some use images and are equipped with other alternatives in the process of completion. Subjects from quite skilled groups have deficiencies in each written text, drawing, and mathematical expressions.
