Abstract

The ability to think in humans are naturally including the ability to think mathematically. Many activities conducted in the thought process among others see the possibilities that exist, making analysis and synthesis to reason or draw conclusions from the existing premises, weigh adan decided. Thinking activities in this section is closely associated with the process of probabilistic thinking. The thought process is one of the high-level thinking skills. However, there are still many students who have not been able to develop thinking skills to solve problems probabilistic.This caused one of them is still weak reasoning ability of students, especially in solving problems such as permutation and combination opportunities. In addressing this issue, we need a good analysis and the whole picture, so that it can provide the right solution. The analysis can give an overview to the problem is to consider the level of probabilistic thinking as developed by Jones were split into four levels of thinking that is subjective, transitional, informal quantitative and numerical. The results obtained from the test sheets and interviews show that the thinking of students Class XI SMA Negeri 9 of Bengkulu in resolving the permutations and combinations in general are still at the level of the transitional thinking. Students are still experiencing a process of change of the thought process based on his experience of being thought processes of quantification. Keywords: probabilistic thinking process, permutations, combinations

One of purposes that want get in the mathematics lesson, According to Permendikbud Number 58, 2014 is ability of mathematical communication. The ability of mathematical communication can be facilitated on learning model of ELPSA (Experiences, Language, Pictures, Symbols, Application). Kinds of this research is descriptive, which aims to describe students mathematical communication abilities based on indicators on the ELPSA  learning model in grade VIIIA Junior Hight School number 10 south Bengkulu. The data obtained through skills test, mathematical communication and interview. Then, it analysis with some steps such as, data reduction, presentation of data, verify data dan draw condutions. The result of this research show that it has been able to achieve three indicators which are desired that is express the ideas and mathematic information on understand and evaluation the mathematic ideas, using terms, mathematical notations its structure, and present ideas. Keywords: Mathematical Communication Skill, ELPSA Model
