<![CDATA[Upaya yang dilakukan oleh guru dalam meningkatkan hasil belajar matematika adalah dengan memilih metode pembelajaran yang sesuai dengan tujuan yang ingin dicapai. Salah satu metode pembelajaran adalah dengan menggunakan pendekatan PAKEM (Pembelajaran Aktif, Kreatif, Efektif dan Menyenangkan). Tujuan penelitian adalah untuk mengetahui pengaruh pembelajaran matematika dengan pendekatan PAKEM terhadap hasil belajar siswa, dan untuk mengetahui sikap siswa terhadap pembelajaran matematika tersebut. Penelitian ini menggunakan pendekatan kuantitatif dan metode quasi-experiment desain yang digunakan adalah non-equivalent control group. Pada desain ini, kelompok kelas yang sudah ada kemudian dipilih secara tidak acak untuk menentukan kelas eksperimen dan kelas kontrol. Kelas eksperimen diberi perlakuan pembelajaran matematika dengan menggunakan PAKEM sedangkan kelas kontol diberi perlakuan pembelajaran konvensional. Hasil penelitian adalah siswa yang memperoleh pembelajaran matematika dengan pendekatan PAKEM lebih baik daripada siswa yang memperoleh pembelajaran konvensional. Selanjutnya siswa pada umumnya menunjukkan sikap yang positif terhadap pembelajaran matematika dengan pendekatan PAKEM.]]>

<![CDATA[This research aims to know the tendency of learning outcomes and motivation in learning mathematics X grade of Accounting at SMK 1 Bawang, Banjarnegara by using Active Learning Methods and types of GGE students who are taught using conventional methods, to determine which methods will give good achievement in mathematics, between active learning method or type GGE and the conventional method, to know which the mathematics learning motivation that is better among high, medium, and low, to know the interaction between of learning method and motivation level. The population of the study was the students X grade at SMK 1 Bawang, Banjarnegara in academic year 2013/2014. Samples were selected 2 classes at 65 students. Data analysis technique used descriptive analysis and hypothesis testing with two-way ANOVA F test. The results of the analysis can be concluded learning outcomes mathematics of the students who are taught with active learning methods GGE type classified as very high (, learning outcomes mathematics of students who are taught with the conventional method is exceptionally high ( ; taught students 'motivation with GGE type of active learning methods is high (, while the students' motivation classes taught by conventional methods were moderate (; classes are taught by active learning method has type GGE mathematics learning outcomes better than the class taught by the conventional method "; mathematics learning outcomes of students with high motivation better than medium and low motivation, students with motivation are better than low motivation.  there is no interaction between learning method based on the motivation level of students' mathematics learning]]>

<![CDATA[Efforts to improve creativity and X.1 class student achievement through learning model Intellectually Auditory Repetition (AIR) SMA Negeri 1 Moga, Pemalang. This research is Classroom Action Research (CAR). The subjects in this study were grade students X.1 of SMA Negeri 1 Moga , amounting to 36 students. Data collection techniques in this study with observations to determine the creativity of students in learning, a questionnaire to obtain data on student creativity, engineering tests to obtain data on student achievement, technical documentation for the data reinforce the observation results. The trials used to test the instrument test item, whereas the observation sheet used to determine the level of creativity of students. Data analysis techniques for observation sheet was conducted to determine students' creativity, while learning mathematics achievement tests done by calculating the average value of the class. The results showed that after learning model applied Intellectually Auditory Repettition (AIR), creativity and learning mathematics achievement increased. This can be shown by an increase in the average yield percentage creativity of student learning based on observation sheet for each cycle is the pre-cycle for 34.26% of student creativity, the creativity of the students first cycle of 45.36%, for the second cycle of 63.43 %. While the average value of learning mathematics achievement of students increased from an average initial value of 50.42 into a 77.59 in the first cycle andthe second cycle becomes 83.50. Given Repetitin Intellectually Auditory learning model (AIR) to encourage the creativity of students and also to improve the achievement of students learning mathematics. It is expected that schools can implement the model lesson.]]>
