A Comparison of Statistics Learning Through CTL and Problem-Posing Approach in Terms of Learning Achievement and Interest in Learning Mathematics AbstractThis research aim s to describe the effectiveness of statistics learning through the CTL approach and problem posing approach in terms of learning achievement and interest in learning mathematics and to investigate which approach is more effective in learning mathematics for Vocational School students. This research is a quasi-experimental research using the pretest-posttest non-equivalent group design. The research population comprised all year XI students of SMK Negeri 5 Yogyakarta. From the population, two classes were randomly selected as the research sample. To test the effectiveness of statistics learning through the CTL and problem-posing approach, one sample t-test was used in the aspect of learning achievement and a proportion test on the aspect of interest in learning. The data were analyzed using the T2Hotelling’s test to compare the effectiveness of the CTL approach and problem-posing approach. If differences in effectiveness were found, then further study of t-univariate was done to determine certain variables that contributed to the overall difference. The results show that: (1) statistics learning through the CTL approach is effective in terms of learning achievement; (2) There is a significant difference of students' mathematical statistical reasoning ability in the three categories of TKASM (good, medium and low) at significance level of 5%. (3) The ability of students' mathematical creative thinking to get an open-ended learning approach is better than those who get regular learning. (4) There is a significant difference between students' mathematical creative thinking ability in TKASM Tinggi to TKASM Sedang at the level of significance of 5%.]]>

<![CDATA[This study aims to analyze the errors of MTs students on the concept of a one-variable linear equation (PLSV), using a qualitative descriptive research method. The data collection in this study was carried out by providing 7 questions about the concept of a one-variable linear equation (PLSV) and interviews with the data processing technique used, namely analyzing student errors, based on indicators of error in understanding the definition of a one-variable linear equation. The subject that the researcher used was 19 students of class VII-B in one of the private MTs in Cipeundeuy District with heterogeneous abilities. From the results of the study stated that; (1) the type of error students with low ability make is wrong when determining which incluades a one-variable linear equation, not a one-variable linear equation and cannot mention the variables and constants of an equation; (2) the type of error made to the medium ability student cannot mention the constant of an equation; and (3) the type of error of students with high ability is wrong in mentioning constants. So it can be concluded that the cause of student errors is that there are still many who do not understand the basic concept of a one-variable linear equation.]]>

<![CDATA[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.]]>
