Özet:

The research aims to find: the factors causing the low mathematical communication ability of students, ways to increase mathematical communication in terms of independent learning and recommendations for student success. As a subject for elementary level students of the undergraduate mathematics education program, Pancasakti University,Tegal-Indonesia. The data were collected by means of tests, observations, interviews and documentation, then triangulation was carried out to check the truth and analyzed descriptively. The results showed students' mathematical communication ability to describe mathematical symbols, ideas, structures and sentences to complete, but they got deadlock in communicating between components into mathematical sentences. Searching for student work portfolios is not procedural. Recommendations, to improve mathematical communication ability, a module-assisted e-learning is carried out which contains various basic materials and enrichment materials. When online students are given assignments to study and work on questions from previously given modules to strengthen their independence learning. This is to lure students to improve their mathematical communication ability. When face-to-face is used as a forum for discussion, highly capable students help become tutors. Here the lecturer facilitates students to interact by giving questions that show mathematical communication and giving examples of work with good mathematical communication.
