Abstract

This study aims to assess the difference in learning outcomes of students who receive realistic mathematics learning approach with those who obtain the conventional one. The study is conducted using pre-test post-test control group design with the entire population of eighth grade students of SMP N 2 Lhokseumawe as sample. In this study, purposive sampling technique is used for sampling. Data collection is conducted by giving test and non- test. The test includes cognitive testing on circle after the treatment is given , and the non – testis given using questionnaire to measure students’ attitude and response towards the realistic mathematics learning. Furthermore, the statistical test used in this study is the t-test. The data also illustrates that it follows the normal curve and it is homogenous. In order to test the hypothesis using the t-test, df (degree of freedom)= n1 + n2 - 2 = 30 + 31-2 = 59. As a result, it is obtained that t t table is 3.502 1.671 .  In conclusion, the study finds that 1 ) the students who receive realistic mathematics learning approach perform better on the test compare to those who do not receive the treatment (2 ) Students’ response towards realistic mathematic approach is positive

Abstract

The ability of mathematical communication  is one of the ability that are required in the curriculum in learning mathematics in school. Weak mathematical communication skills of students is one of the problems in the learning of mathematics in high school that need to be solved . This study aims to examine the ability of mathematical communication between the students who acquire STAD model with conventional learning . This research is an experimental study with a control group study design pre-test post-test . The study population was all students of SMA Negeri 1 Tangan-tangan Class XI , while the sample taken by purposive sampling two classes is class XI IA1 as an experimental and class XI IA2  as the control class. Two kinds of instrument are used to collect the data. They are test and nontest they include the ability of mathematical communication test. While nontest consist of questionnaires of attitude scale and observation sheets. They include the ability of mathematical communication test, while nontes of questionnaires and observation sheets. To see whether the students' mathematical communication skills between gain learning STAD model is better than conventional learning group that used the t-test at the 0.05 significance level after testing prerequisites are fulfilled. Baser on the data and results of statistical tests were analyzed with Microsoft Excel 2007 to interpret students' mathematical communication skills and attitudes of students towards learning model STAD. Based on this research, it is known that: 1) The ability of mathematical communication of studend who acquire cooperative learning STAD model better than students who received conventional teaching; 2) There are differences in mathematical communication skills improvement among subgroups of low, medium and high on student learning using the model STAD so that the learning of mathematics with this model improve mathematical communication skills are not evenly for each subgroup of students. 3) Based on the analysis of attitude scale questionnaire , the students' positive attitudes towards learning mathematics with STAD model. 4) In general, the learning of mathematics by using STAD model makes the students more active in the learning time, students have much opportunity to explore his ability and help each other. 5) Barriers in implementing STAD models namely: the willingness of insufficient time, students' skills in reading comprehension and item is still low .
