Abstract

The purpose of this study was to identify trends in mathematics achievement of students of class VII SMP N 2 Girisubo Gunungkidul academic year 2013/2014.The population in this study were all students of class VII SMP N 2 Girisubo Gunungkidul consisting of four classes with a random sampling technique. Test the validity of the instrument items, level of difficulty, different power and reliability. Prerequisite test used test for normality of distribution and homogeneity of variance test data analysis using correlated t test. Comparatively no positive effect on the use of student worksheets grade mathematics achievement SMP N 2 Girisubo Gunungkidul academic year 2013/2014 t -4,457 < -t -1,713 table. Thus the method can improve the students' worksheets grade math achievement SMP N 2 Girisubo Gunungkidul academic year 2013/2014.

Abstract

The purpose of this research is to know the implementation of Tamansiswa precept values in teaching mathematic activity to shown the students characters. The research is qualitative descriptive research. The data gets from an observation, an interview, and documentation. The research shows that mathematic teachers of seventh and eighth grade in Taman Dewasa Ibu Pawiyatan Junior High School are already implementing the values of Tamansiswa precept in teaching activity. The implementation of Tamansiswa precept values is done by using variety methods of teaching mathematic such as, communicative method, guided discovery method, cooperative method (STAD), and task method. The character of student which already organized is shows in VII A class, while VII C still needs a process to build the student character. The organized student character shows by the freedom attitude of student (free for have a notion), independent, diligent, not to yield an inch, have a curiosity, and through.

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.
