Abstract

The research aims to know the effectiveness of learning mathematics with Indonesian Realistic Mathematics Approach to critical thingking skills of student class VII SMP Negeri 3 Pandak academic year 2013/2014, to know which the critical thingking skills that is better among high, medium, and low student motivation, to know interactions between application of learning model and student motivation. Kind of the research is a quasi-eksperimental. The population of this research was all students of class VII consist of 4 classes in SMP Negeri 3 Pandak academic year 2013/2014. The research sample of 2 classes was taken by cluster random sampling technique. The instrumens of the research consist of documentation, critical thingking math test,observation and questionnaire. The data analysis uses descriptive analysis and two-way ANOVA. The results of the analysis in the research are : 1) Learning mathematics with Indonesian Realistic Mathematics Approach is more effective than conventional approaches to critical thingking, 2) Critical thingking skills of student who have high motivation to learn are  better than students with medium and low learning motivation, critical thingking skills of students with medium learning motivation are better than students with low learning motivation, 3) There is no interaction between learning model and motivation to learn of students based on the critical thingking skills. Thus, the suggestion of the result of this research is learning mathematics with Indonesian Realistic Mathematics Approach can be implemented to improve student’s critical thingking.

Abstract

The purpose of the research was to find out correlate between  learn interest, and learning area with mathematics learning achievement on 10th  grade students at the whole district of Kalibawang Yogyakarta. The genre of this research is descriptive researchment. The population in this research were all students of 10th grade students at the whole district of Kalibawang Yogyakarta with amount 48 students and the samples taken at sampel jenuh with amount 48 students. Data collection method used was a questionannaire and a documentation. Analysis using descriptive analysis of data, multiple regression, and partial correlation. In the major hypothesis test is obtained R = 0,451 and R2 = 0,203 with sig=0,006 < 0,05. Then in the first minor hypothesis test is obtained ry1-2 = 0,297 with         sig=0,043 < 0,05; and the second minor hypothesis test is obtained ry2-1 = 0,343 with sig=0,018 < 0,05. So there is a positive and significant correlation between learn interest, and learning area with mathematics learning achievement on 10th  grade students at the whole district of Kalibawang Yogyakarta as collective and partial. It is expected that students care about learn interest, and learning area mathematics learning achievement increasingly.

Abstract

The aim of this research was to describe about teaching learning process using Cooperative Integrated Reading and Composition (CIRC) to increase student’s active and study result to the eleventh grade student’s at Miftahul Huda Bulu Temanggung. The hypothesis of this research was applying Cooperative Integrated Reading and Composition (CIRC) could increase student’s active and student’s study result. This research was Classroom Action Research (CAR) collaboratively.The research result showed that after applying Cooperative Integrated Reading and Composition (CIRC) in teaching learning process, the student’s active increasing. Before this research the students were passive to listen to the teacher’s explanation but after this research the students were more active to ask and discuss in group.  Means student’s score increased, first 60,35 score, increasing in first cycle was 68,81 and increasing second cycle was 72,10. From the result above, it showed that Cooperative Integrated Reading and Composition (CIRC) method could increase student’s active and study result.

Abstract

descriptively, the purpose of this study is to know the tendency students’ of computational skills, independece of  learning, learning environment and the academic mathematics achievement of the students class VIII SMP Negeri of  in Panjatan district on 2013/2014 academic year. Correlatively, the purpose is to determine the relationship between computational skills, independece of  learning,  learning environment and the academic mathematics achievement of the students class VIII SMP Negeri of  in Panjatan district on 2013/2014 academic year. The population of this study was all students of VIII SMP Negeriin Panjatan district on 2013/2014 academic year. Sampling is taken by using cluster randomsampling technique.. The researcher took and selected class of  VIII B and VIII C SMP N I Panjatan and class VIII A and VIII B SMP N 2 Panjatan as the sample class with the number of responders is 108 students. The data analysis is using multiple correlation and multiple regression of two variables. The results of this descriptive study showed that the computational skills is in a very high category, while their independece of  learning is in the high category, while their the  learning environment is in the high category and their learning mathematics achievement in a high category.From the calculation of multiple correlation test, the value ofR=0,647 by p= 0,000 <α=0,05, it means that there is a positive and significant relationship between computational skills, independece of  learning,  learning environment and the academicmathematics achievement.

Abstract

The purposes of this study are to understand : (1) the tendency of creative thinking ability of sixth grade students who were taught using inductive learning model, (2) the tendency of creative thinking abilities of students of class VII are taught using conventional learning model, (3) Is the ability to think creatively math studentsVII class taught by using inductive learning model would be more effective than students who were taught using conventional learning models. Hypotesis in this research was "The ability to think creatively Class VII student of mathematics Park Adult Mother Pawiyatan Yogyakarta academic year 2013/2014 is taught using inductive learning model is better than the students who are taught using conventional learning model”. This research used experimental method, wich the experimental group taught by inductive learning model compared to control group that taught by conventional methode. The number of student in experimental group and control group were equal, 28 student. The collection of data used in this research is a test technique, then the data were analyzed using the t test correlated.  From the paired t test, the result of this research showed that the value of   = -2.626 compared to  = -2.052 can be concluded that the hypotesis was accepted. From the comparison of experimental group mean and control group mean can be interpretated that experimental group mean was better than control group mean; 15,964> 14,071. From this research can be suggested to the teacher to use inductive learning model to improve the ability to think creatively.
