Abstract. The purpose of this research is to know the understanding of mathematical concepts of students with the use of conceptual attainment model is better than the understanding of students' mathematical concepts with conventional learning. This research is quasi experimental research. The research design used was randomized subjects posttest only control group design. By selecting a Class VIII-2 sample as an experimental class and class VIII-1 as a control class of analytical techniques using the t-test as a hypothesis test, the prerequisite test is a normality test and homogeneity test. Based on the hypothesis test, t-test, obtained the price tarithmetic = 3.073 and price ttable = -1.997 at the real level of 0.05. Because tarithmetic > ttable, so Ha accepted and H0 rejected. So it can be concluded that the ability to understand the concept of mathematics students using conceptual learning model attainment better than the ability to understand the concept of mathematics students using conventional learning model.Keywords: Concept Attainment, Understanding of Concept

AbstrakLatar belakang penelitian ini yaitu permasalahan masih rendahnya kemampuan pemahaman konsep matematis pada mahasiswa. Tujuan dari penelitian ini yaitu untuk mengetahui efektifitas pembelajaran take and give dalam upaya mengembangkan kemampuan pemahaman konsep matematis pada mahasiswa. Adapun populasi dalam penelitian ini yaitu mahasiswa tingkat III pada salah satu perguruan tinggi swasta di kabupaten Garut, dengan sampel yaitu mahasiswa tingkat IIIA dan IIIB. Instrumen dalam penelitian ini yaitu berupa tes kemampuan pemahaman konsep matematis dalam bentuk pretest dan posttest. Analisis data yang dilakukan terhadap hasil pretest dan posttest yaitu diawali dengan uji normalitas, kemudian uji homogenitas dan uji-t. Hasil penelitian ini secara garis besar menunjukan bahwa terdapat perbedaan kemampuan pemahaman konsep matematis antara mahasiswa yang memperoleh pembelajaran take and give dan yang memperoleh pembelajaran ceramah biasa, dimana mahasiswa yang memperoleh pembelajaran take and give memperoleh hasil akhir kemampuan pemahaman konsep matematis yang lebih baik daripada yang memperoleh pembelajaran ceramah biasa. Hal ini menunjukkan bahwa pembelajaran take and give dapat secara efektif mengembangkan kemampuan pemahaman konsep matematis. AbstractThe background of this research is the problem is still the low ability of understanding mathematical concepts in the students. The purpose of this study is to determine the effectiveness of learning take and give in an effort to develop the ability to understand mathematical concepts in students. The population in this study are third-grade students at one private college in Garut district, with a sample of students IIIA and IIIB. Instruments in this research is a test of ability to comprehend mathematical concepts in the form of pretest and posttest. Analysis of data conducted on the pretest and posttest results is started with the normality test, then homogeneity test and t-test. The results of this study broadly indicate that there is a difference in the ability of understanding mathematical concepts between students who receive learning take and give and who get the ordinary lecture learning, where students who get learning take and give gain the end of the ability of understanding the concept of mathematical better than those who obtained ordinary lecture lessons. This suggests that take and give learning can effectively develop the ability to understand mathematical concepts.

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.
