Abstract: The purpose of this research was describing the ability of mathematical communication in solving the mathematics problem. This research was include of study case situation analysis research. The subjects of this research consisted of four students of Class IXb of the ninth grade SMPN 1 Surakarta in the second semester of the academic year 2012/2013.Â They were two students who had field dependence cognitive style and two students who had field independence cognitive style. The subjects were taken by using the purposive sampling technique. The data of this research were gathered through think aloud method. The data were then analyzed by using the technique with the procedureas follows: (1) the data were classified on the basis of the indicators of mathematical communication after the data had been obtained from the first and the second collections; (2) the data were presented in table form; and (3) the conclusions were drawn. The validity of the data was conducted by using time triangulation. The result of this research were analyzed by using constant comparison in which subject in i (i= 1, 2) with the j (j= 1, 2) cognitive style which was already valid as well compared with subject in k (k= 1, 2) with the the j (j= 1, 2) cognitive style which was already valid as well. The equal ability of mathematical communication was made the main finding wheares the different ability of mathematical communication was made the other finding. The result of this research valid because of the dependability proved. The ability of mathematical communication of the students with the field dependence cognitive style is different from that of those with the field independence cognitive style. The students with the field dependence cognitive style can communicate the ideas in written way well but they have difficulties in communicating ideas in spoken way as well as inclination to receive information without reorganizing it in such a way that the problem-solving ideas presented cannot reveal the actual problem solution. Meanwhile, the students with the field independence cognitive style can communicate the ideas well in both spoken and written ways and process as well as reorganize information in such a way that the problem-solving ideas presented can reveal the actual problem solution. Keywords: Mathematical Communication. Problem Solving. Cognitive Style.

This study aims to see the effect of realistic mathemathic education models on students' mathematical reasoning abilities in terms of learning styles. This type of research is quantitative. Data collection techniques used are essay tests and interviews. The data analysis technique used is hypothesis testing using anava 2 roads. However, before the anova test is carried out, the normality, homogeneity and balance test are carried out first. Based on the data that has been known that normal data, based on the same and balanced variance, the 2-way ANOVA test results show that there is an influence of the RTE model on students' mathematical reasoning ability, namely the reasoning ability of students with the RME model treatment is better than mathematical reasoning ability with conventional treatment methods. In addition, there is the influence of student learning styles on students' reasoning abilities.

In additionthere is the influence of student learning styles on students' reasoning abilities.Furthermore, mathematical reasoning ability of students who have who have a visuallearning style is better than students who have an auditory and kinesthetic learningstyle. While students who have kinesthetic learning styles are better than studentswho have auditory learning styles. There is no interaction between the treatment oflearning with the learning styles category of students. Means, there is no differencein the effect between the learning treatment and learning styles of students on theability of mathematical reasoning on students with the treatment of learning usingthe Realistic Mathematics Education model or using conventional learning models.Key Word: Realistic Mathematical Education Model, MathematicalReasoning Ability, Learning Styles

Â The Kurikulum 2013 â€“Indonesia's novel Curriculum invented in 2013â€“ is implemented through activity-based learning using a scientific approach. Curriculum changes do not only occur in the dimensions of the plan/document, but in its implementation in the quality of the process which has an impact on learning outcomes. This research aims to determine the implementation of the Kurikulum 2013 scientific approach and its impact on the quality of the learning processes and outcomes at MAN in Lampung Province. The research uses a mixed methods with sequential mixed methods design. The respondents consisted of 26 teachers and 126 students. Data were collected by conducting interview, observation, documentation, and questionnaire. The validity was tested by Pearsonâ€™s validity and Cronbach Alpha reliability. The results showed that teachers can apply a scientific approach to the implementation of the Kurikulum 2013 well. It can be seen from the teacherâ€™s ability to prepare lesson plans, though there are some teachers (working period of 21 to 30 years) who are constrained during the learning process, such as observing the learning and not being able in presenting the media. The scientific approach has a very good impact on the quality of the learning process and outcomes. It can be seen by the increase in student learning outcomes.
