Abstract

The aims of the research were to know (1) the learning model that had better study achievement, (2) the stage of the initial capacity that had the better achievement, (3) the difference of the studying achievement in each initial capacity of the consistent students for each learning model, (4) the stage of the students with initial capacity which had the better study achievement in CPS learning model, and (5) the stage of the students with initial capacity which had better achievement in MPL learning model. This research was the quasi experiment with four classes as the sample of the research. Variable of the research was the study achievement of the students, the initial capacity and the learning model. The method used was the test method. Data analysis used was the analysis variance test. It could be concluded that (1) the achievement of the student with the CPS learning model was better if compared with MPL, (2) the students with the high ability in the initial had better achievement compared with intermediate and low ability, (3) To the students who have intermediate ability, CPS learning model is better if compared with MPL, (4) to CPS learning model, the students with high ability in the initial had the better achievement if compared with the students who have intermediate and low ability, and (5) to MPL, the students with high ability in the initial had the better achievement if compared with the students who have intermediate and low ability.Tujuan penelitian adalah untuk mengetahui (1) model pembelajaran yang mempunyai prestasi belajar yang lebih baik, (2) tingkatan kemampuan awal yang memiliki prestasi yang lebih baik, (3) perbedaan prestasi belajar pada tiap kemampuan awal mahasiswa untuk tiap model pembelajaran, (4) tingkatan kemampuan awal mahasiswa yang mempunyai prestasi belajar yang lebih baik pada model pembelajaran CPS dan (5) tingkatan kemampuan awal mahasiswa yang mempunyai prestasi belajar yang lebih baik pada model MPL.

Abstract

The purpose of this study was to confirm the factors that influence the sociomathematics norm. The method used in this research is the ex post facto. The subjects in this study were seventh-grade junior high school students in the city of Yogyakarta, Indonesia (264 students) taken by cluster random sampling. The instrument used was a sociomathematics norm observation sheet consisting of four factors are (1) the experience of mathematics, (2) the explanation of the mathematics, (3) mathematical differences, (4) mathematical communication. Data analysis using structural equation models with the Confirmatory Factors Analysis. The results showed that the modified path analysis obtained goodness of fit mostly in the fit category, so overall the sample covariance matrix is the same as the estimated covariance matrix.

Abstract

The sociomathematics? norm is a social norm of mathematical nuance, with sociomathematics? norms; the social intelligence possessed by learners can be developed because his norm is strongly associated with negotiation and interaction. The purpose of this article is to know the improvement of sociomathematics? norms student of mathematics education by using cooperative learning of Team Accelerated Instruction. This research uses pretest-posttes control only group design. Sample size in this research is 38 people in class C of course of Numerical Method taken by cluster random. The sociomathematics? norm is obtained using an observation sheet. The data obtained were analysed using N-gain and t-test (paired-samples T Test). Based on the result, it can be concluded that the learning model of Team Accelerated Instruction can improve students' sociomathematics? norm ability through numerical method

Abstract

This study aims to determine the effectiveness of the Student Teams Achievement Division cooperative learning model in terms of mathematics achievement. This type of research is an experimental study with a population of eighth grade students of SMP N 3 Bantul taken using cluster random sampling technique. research instruments use tests on the subject matter of opportunity. data analysis techniques using t-test by considering the assumption test for the test. From the results of the study it can be concluded that on learning achievement, the Student Teams Achievement Division model is more effectively used in learning mathematics in the material opportunities when compared with the direct learning model. related to this result, the Student Teams Achievement Division Model can be used as an alternative in learning mathematics, especially in the material opportunities.

Abstract

This research aims to test the effectiveness of the Team Accelerated Instruction (TAI) towards the ability of the students to solve mathematics problems based on their initial ability. This study is an experiment with 367 students involved as the research sample taken using the cluster technique. The research variable is the problem-solving ability, the initial ability, and the learning model. Analysis of variance was used to analyze the data which leads to the conclusions that (1) the TAI is more effective than the Direct Instruction (DI); (2) the students having moderate initial ability performed better compared to the lower and the higher initial ability; (3) among the students with moderate initial ability, TAI was more effective to be used than DI; and (4) in the implementation of  TAI and DI, the problem solving ability of the students is relatively similar.

Abstract

Artikel ini merupakan kajian dari ajaran Ki Hajar Dewantara dan nilai-nilai agama yang diimplementasikan di dalam pembelajaran matematika. Tujuannya untuk membina karakter siswa agar tidak mudah terpengaruh budaya negatif bangsa lain. Pada dasarnya, integrasi antara agama dan ajaran Ki Hajar Dewantara dapat direalisasikan, dan hal itu sesuai dengan kemampuan berpikir 4Cs. Tamansiswa selaku organisasi yang didirikan oleh Ki Hajar Dewantara seharusnya menjadi pemrakarsa dan penggerak dalam pembinaan karakter.
