This study was conducted to determine the effect of REACT strategy assisted by GeoGebra software on students' mathematical representation ability. This study was quasi-experimental with a quantitative approach. The design used in this study was The Nonequivalent Posttest Only Control Group Design. Four posttest questions were given to 25 students of Class VIII A and 25 students of Class VIII B at SMP Negeri Arun Lhokseumawe (public middle school). The data obtained from the posttest results were analyzed by data normality test and data homogeneity test, then hypotheses were tested using a t-test to see the effect of REACT strategy assisted by GeoGebra software on students' mathematical representation ability. The results of the data analysis of the posttest score tested using the t-test, the sig value was obtained. (2-tailed) of 0.000 > 0.05. This showed that there was a significant effect of using the REACT strategy assisted by GeoGebra software on students' mathematical representation ability.

The purpose of this study was to determine the effect of the method of playing a role in student confidence in Indonesian subjects. The quasi-experimental method is used as a research method with the Non-Equivalent Control Group Design research design. The population of all students in the primary school state of Cilaku. Samples were taken as many as 48 students from the VA class of 24 students as the control class and the VB class of 24 as the experimental class. The data analysis technique used in determining the average, calculating the standard deviation, normality test, homogeneity test, and t-test. The results showed that the variable of students 'confidence using the role-playing method obtained an average posttest score of 78.33. In contrast, the results of students' confidence using conventional learning received an average posttest score of 66.17. Then the hypothesis test is performed, which shows the results of t count 4.09 and t table = 2.074 with n-2 = 24-2 = 22 and a significance level of 0.05. Based on the t count ˃ t-test criteria, Ha is accepted, and Ho is rejected. Thus it can be concluded that the role-playing method influences students' confidence in Indonesian subjects.

The Impact

The research is aimed to produce an effective social-personal guidance to develop students' moral behavior. This research uses quantitative approach with quasi experimental method and non-equivalent control group design to students class VIII of SMP Negeri 26 Bandung. Data analysis techniques used to find out the effectiveness of personal-social guidance in developing the moral behavior of students in SMP Negeri 26 Bandung Academic Year 2017/2018, include: 1) normality test; 2) homogeneity test; and 3) independent t test. The results show that in general social-personal guidance is not effective in developing students' moral behavior. But in particular there are five significant indicators, which is; 1) impose obligations as a child; 2) help others sincerely; 3) share / share information; 4) show concern for others; 5) guiding others to the task, and two insignificant indicators, namely; 1) understanding school rules; 2) consider the impact of lying.

This study aims to determine the comparison of students 'mathematical representation ability through the Project Based Learning (PjBL) Model and the students' mathematical representation ability through the conventional model. The PjBL model is a student-centered, innovative, project-based learning model and positioned teachers as effective facilitators in the contextual learning related to real life situation. This research employed quasi-experimental design. The research applied the posttest only non-equivalent control group design through randomized cluster sampling. The data collection technique used was test. The instrument used to collect the data was the essay test. Data analysis was conducted using independent sample t-test. The result of the data calculation through the Independent-Sample T-Test test obtained the significance level of 0.913 means that the students’ mathematical representation ability was better after the learning through Project Based Learning (PjBL) model was conducted compared to the students' mathematical representation ability through a conventional model. This means that the PjBL model is more influential on students' mathematical representation ability.

Abstract. This study discusses the effectiveness of the use of the Show and Tell method in improving the learning achievement of fourth grade students in Akhlak subjects in Madarasah Diniyah Takmiliyah Awaliyah Wasilatunnaja in the 2015/2016 academic year. This research uses a quantitative method through an experimental approach with nonequivalent control group design. Based on the results of data analysis based on the normality test, homogeneity test, and t test, it is known that the results of posttest, is normal and homogeneous, the sig (2-tailed) value of 0.145 with (df) 45 where 0.145> 0.05 . Then, according to the basis of decision making in the independent sample t-test, it can be concluded that Ho is accepted and Ha is rejected, which means that there is no difference between the average learning outcomes of the experimental class and the control class. Which also shows that there is no significant difference in learning outcomes between the experimental class and the control class. In other words the show and tell method is not effective enough in improving student learning outcomes in moral subjects. Abstrak. Penelitian ini membahas tentang efektivitas penggunaan metode Show and Tell dalam meningkatkan prestasi belajar siswa kelas IV pada mata pelajaran Akhlak di Madarasah Diniyah Takmiliyah Awaliyah Wasilatunnaja pada Tahun Ajaran 2015/2016. Penelitian ini menggunakan metode kuantitatif melalui pendekatan eksperimen dengan nonequivalent control group design. Berdasarkan hasil analisis data dengan berdasarkan pada uji normalitas, uji homogenitas, dan uji –t, diketahui bahwa hasil dari postest normal dan homogen, maka diperoleh nilai sig (2-tailed) sebesar 0,145 dengan (df) 45 di mana 0,145 > 0,05. Maka sesuai dasar pengambilan keputusan dalam uji independent sample t-test maka dapat disimpulkan Ho diterima dan Ha ditolak yang artinya bahwa tidak terdapat perbedaan antara rata-rata hasil belajar kelas eksperimen dan kelas kontrol. Yang juga menunjukkan bahwa tidak ada perbedaan yang signifikan hasil belajar antara kelas eksperimen dan kelas kontrol. Dengan kata lain metode show and tell ini tidak cukup efektif dalam meningkatkan hasil belajar siswa pada mata pelajara akhlak.

This research background was the application of less optimal Social Sudies Learning Process in schools in enhancing students’ critical and meaningful thinking skills and at the Social studies learning which were still taught separately based on appropriate field of studies such as Geography, Sociology, History and Economics. This research aimed to find out the effect of integrated Social studies Learning towards the students’ critical and meaningful thinking skills enhancement. The research method applied in this study was quasi experimental research using Nonequivalent Control Group Design. One class was chosen as an experimental class with Integrated Social studies Learning and one control class was choosen with separated Social studies learning. The data technique collection used was in the form of test result which was supported by observation and questionnaire. The analysis technique of test data to examine the research hypothesis applied SPSS version 16 with the analysis tools: normality test, homogeneity test, parametric analysis with t test and gain. The test findings showed that the learning of Integrated Social studies affected by the students’ critical and meaningful thinking skills enhancement. The learning of this Integrated Social Science was recommended as a learning alternative which was able to enhance students’ critical and meaningful thinking skills
