Peningkatan Kemampuan Berpikir Kritis Matematis Siswa melalui Penggunaan Metode Improve pada Materi Sistem Persamaan Linear Dua Variabel

This study aimed to analyze the improvement of critical thinking skills Improve mathematical methods to the material system of linear equations of two variables. The method used is the method of quasi-experimental data analysis using different test or the average of the t-test. Population affordable in this study were all students of class VIII A and VIII B grade SMP 248. Samples were obtained through random sampling techniques, namely random sample collection techniques. Testing requirements analysis consists of data from test to test methods Liliefors normality and homogeneity tests to test methods bartlett. Based on the results of the testing requirements of data analysis concluded that the two sets of data were normally distributed and homogeneous. Instrument variable mathematical critical thinking skills is a written test consisting of 20 items about. Based on the results of hypothesis testing and data analysis it can be concluded that the critical thinking skills of students who are taught mathematical improve method is higher than conventional methods. Based on these results, it is in an effort to improve students' critical thinking skills teachers should use mathematical methods improve

Pengaruh Kebiasaan Belajar dan Kreativitas Belajar Siswa terhadap Hasil Belajar Matematika (Survey pada SMA di Kecamatan Ciledug Tangerang)

The objective of this research is to investigate the influence of students learning activity and creativity toward the math learning achievement. In addition it is to know simultaneously the influence of students learning activity and creativity toward the math learning achievement. The research method is used in this research is survey. There are 60 students come from tenth grader of SMA Numaniyah and SMA Fatahillah Ciledug Tangerang as sample of the research, interview, questionner, and achievement test are used to collect the data. The descriptive statistical is used to analyze the data beside person double correlation coefficient, determination coefficient and regression analysis T and F  test are used to incate the statistical test. The research was conducted on March 2012. The result of the research show that there is simultaneous influence between students learning activity and creativity toward the math learning achievement of tenth grader students at SMA Ciledug Tangerang. It is stated by the quality regression of Y = -6,227 + 0,85 + 0,683. It indicates that one level of improvement of learning activity and creativity will be followed by the students achievement of -6,227. The students learning activity and creativity variables indicates the significance influence toward the students learning achievement. It is shownby the determination coefficient of R2 = 0,777 and F test score = 99,459
