Abstract

Similarity and Congruences is a part of geometry which is considered by students as a difficult Topic. It was detected by a low result study and incompleteness of learning achievement clasiccaly. The using of Learning Copperative Model type Jigsaw is considered as an alternative to improve learning achievement of MTs Modern Puteri Cindai Alus Students because it can make student has a responsibility on their study and make an active discussion in Solving Problem. The research method is Action Research which consists of four steps, Planning, Action, Observation dan Reflection in two cycles. The research subjects are 20 students of Class IX MTs Modern Puteri Cindai Alus. The research results shows that there ia an improving of results study from middle to good category and leaning achivement classicaly improve from less to good category.

Abstract

This study aims to determine the activities of students in learning subjects through True or False strategy of graph theory by media index cards. Observations show a more focused student activity because students already know the material of what will be learned through the index cards that they get in early learning, and they also know the form of matter or issue that they get when studying the learning material on which they will carry. Students focus on the material presented by the lecturers. At the end of the students' learning spirit in concluding that material has been obtained. Lecturers also seem satisfied when getting feedback from students on material that has been given to the student lecturer. Keyword: true or false, cards, graphs, media

Abstract

The research aimed to study the effect of Problem Based Learning towards the  student’s mathematical literacy skills. This research is an experimental research. The design of this research used post-test-only control design. The population of this research were the whole students on the seventh grade of SMP Negeri 1 Bobotsari. Sampling in this research used cluster random sampling and obtained VII B grade as an experimental class and VII D grade as an control class. The data were collected using mathematical literacy skill test in the form of essay. The results of mathematical literacy skill test on experiment class showed that the average score was 77,81 and the average score on control class was 69,19. After testing the hypothesis was tested using independent sample t-test , a significance value of 0,0115 was obtained, with significance value or α = 0,05. It was concluded that Problem Based Learning was effective toward grade VII student’s mathematical literacy skill in SMP Negeri 1 Bobotsari.

Abstract

Tujuan dari penelitian ini adalah untuk menggambarkan penguasaan kemampuan matematika siswa pada materi fungsi, dan mendeskripsikan kemampuan penalaran dan komunikasi pada setiap skor dengan menggunakan rubrik penilaian unjuk kerja. Metode deskriptif kuantitatif digunakan dalam penelitian ini dikarenakan terdapat relevansi pada proses awal sampai kesimpulan yang tersusun. Adapun, sampel yang diambil adalah sebanyak 77 mahasiswa tingkat satu pada salah perguruan tinggi swasta tahun akademik 2014/2015. Berdasarkan hasil penelitian dapat disimpulkan bahwa: 1) kemampuan matematis mahasiswa secara klasikal telah mencapai ketuntasan yang ditandai dengan nilai rata-rata diatas Kriteria Ketuntasan Minimum (KKM), sebaliknya ketuntasan secara individual hanya mencapai 63%. 2) Kemampuan mengkomunikasikan gagasan ke dalam bentuk digram matematika secara keseluruhan hampir lengkap, jelas, efisien, dan tidak ragu-ragu. Sedangkan, untuk kemampuan menggunakan ide-ide dan prosedur penalaran matematika untuk menarik kesimpulan yang telah dibuktikan, secara keseluruhan sebagian besar adalah benar, walaupun, masih terdapat kesalahan perhitungan yang serius. Kata Kunci : penalaran matematis, komunikasi matematis.

Abstract

Teaching aids in the world of education is a medium that mediates to help clarifying concepts in learning mathematics. This study aims to determine the efect of the use of toy car props on students’ interest in learning mathematics, especially in comparison material. This research was conducted at SMPN I Bola VII class semester 2 of the 2019/2020 scholl year. This type of research is quantitative by using a quasi-experimental methods. The population of this study were 192 studentsof class VII SMPN I Bola with a sample 0f 23 students in the experimental class and 23 from the control class. The sampling technique used is class random technique. The instrument used in this study was a questionnaire of interest in learning. Before carrying out a hypothesis test it is necessary to do a prerequisite test that is a test for normality and homogeneit. The normality test  obtained significant values in the experimental class and control were 0,136 and 0,620, because the value obtained has a significance level 0f >0,05, it can be stated that the data is normally distributed. For the homogeneity test, the results obtained a significant value of 0,001 at a sisnificant level of 0,05, so it can be said that the data is homogeneous. After the data is normally distributed and homogeneous, it is continued with hypothesis testing. Hypothesis testing used the independent sample t-test obtained value of  t-count > t-table where t-count = 6,49 while t-table = 2,01 which means that the use of toy props has an effect on the interest in learning mathematics in class VII SMPN I Bola where students’interest in learning mathematics increases. Thus the teacher can use toy props related to the material and can be used in matematics learning so that students’ interest in learning mathematics increases.
