Basically every student must master mathematics taught in school because mathematics is a branch of science from various sciences but in fact many students think that mathematics is a complicated lesson that makes them feel dizzy to learn it. In the end their hearts and minds were not open to understanding mathematics when it was explained by the teacher in school so that they had a lot of problems to solve the problem and resulted in incorrect filling in the questions given. The purpose of this study is none other than to analyze students' errors in mathematical communication skills in completing flat-build material. The subjects used were students from one of the high schools in Cihampelas. This research method is qualitative descriptive and the instrument used consists of a mathematical communication ability test. Based on the results of the research, the location of the causes of errors made by students is a concept, procedure and computational error. Factors that cause errors because they do not understand simple concepts, do not know the purpose of the problem, cannot complete mathematical sentences and are not careful in calculating.

The low result of mathematics learning outcomes of students in grade X.1 SMAN 1 Lubuk Si-kaping can be caused by the low ability of students' mathematical communication. Generally, students is feeling difficult to express the ideas, solutions of a problem, whether it can be an answer or a re-sponse to what he or she thinks is poorly understood. One of the solution to solve this problem is by implementing probing technique which is a learning method by using questioning techniques that are digging knowledge of students. The purpose of this study is to describe the ability of students to com-municate the idea mathematically and to know the student learning outcomes during the application of probing techniques in learning mathematics grade X.1 SMAN 1 Lubuk Sikaping. This type of research is pre-experimented with The One-Shot Case Study design. The subject of this research is the students of grade X.1 SMAN 1 Lubuk Sikaping registered in second semester of academic year 2010/2011. Da-ta processing of students' mathematical communication ability is by determining the percentage of the improvement of each indicator on observation sheet in every meeting and also supported by data from the interview. The results of this study illustrate that mathematical communication skills of students have increased from each meeting by using probing techniques, generally. As the results of learning mathematics after using the probing technique is good because 25 students (75.75%) of 33 students class X.1 SMAN 1 Lubuk Sikaping already reached Minimal Completeness Limit which has been ap-pointed by SMAN 1 Lubuk Sikaping (75).
