Abstract

Mathematical reasoning ability and self-regulated learning is one of the objectives of the mathematics learning that should be owned by the students. It is needed relevant learning approaches to develop and improve mathematical reasoning ability and self-regulated learning. One of the learning approaches is Contextual Teaching and Learning (CTL). The purpose of this study was to determine: the improvement of mathematical reasoning ability and self-regulated learning of students who obtain CTL approach and students who receive conventional learning. This study was an experimental research study designed by pretest-posttest control group design. The population of this study was all students of class VII MTsN Rukoh Banda Aceh. While the sample was composed of two classes, namely the experimental class and control class taken by random sampling. The instruments used to obtain research data were the form of mathematical reasoning ability tests and questionnaires of students learning independence. To see the difference in mathematical reasoning ability and self-regulated learning between CTL approach classesand conventional classes used the t-test at the 0.05 significance level. Based on this research, it was known that 1) the improvement of mathematical reasoning ability of studentsacquire learning CTL approach better than students who received conventional learning approaches; 2) the improvement of students independence learning gained CTL approach better than received conventional approaches. CTL approach in learning can affect the better ability of mathematical reasoning and self-regulated learning, in terms of quality there was a significant difference between students who are learning using CTL approach and using conventional learning.

Abstract. Communication skills and mathematical reasoning is one of the objectives of the study of mathematics. Communication is defined as the ability to write, read, listen, examine, interpret, and evaluate ideas, symbols, terms, and mathematical information. Mathematical reasoning is a habit when the brain is well developed and consistent will facilitate the mathematical communicate both written and oral. Therefore, the necessary relevant learning models to optimize, improve, and develop communication and mathematical reasoning abilities of students. One of the cooperative learning models is Teams Games Tournament (TGT). The aim of this study to determine: (1) Is the increase in communication and mathematical reasoning abilities that students acquire learning with cooperative learning model TGT better than students who received conventional learning approaches, and (2) What is the attitude of students towards learning mathematics learning gain with cooperative learning model TGT. This research was experimental research design with pretest-posttest control group design. The population in this study was all students of class XI MAN Darussalam Aceh Besar, which consists of five classes. While the sample was composed of two classes of experimental classes and control classes were taken by random sampling. The instrument used to obtain research data communications test and mathematical reasoning ability, and attitude scale questionnaire. The statistical test used for the data mengalisis increase communication skills and mathematical reasoning was two lanes ANOVA test, while the attitude scale questionnaire was calculated based on a percentage. The results showed that the overall improvement of communication and mathematical reasoning abilities that students acquire learning with cooperative learning model Teams Games Tournament better than students who received study with conventional approaches. From the results of student questionnaire concluded that in general the students had the positive attitude towards learning mathematics using cooperative learning model TGT.Key Word: Learning TGT, Communication, Reasoning

Abstract

Smash is one of the most complex movements in badminton. Along with its development, quantitative analysis is needed to obtain the best smash movement. This research aims to analyze the smash movement kinematically through mathe matical means. The data in this study are primarily obtained through recording and digitizing data on the smash movement of one Aceh Province badminton athlete. The method used to analyze the data is the cubic spline method. This research produces smash movement kinematic data and analysis of translational and angular curves obtained using a cubic spline interpolation approach for three-dimensional coordinates. The kinematic aspects consisted of body segment position, body segment velocity and acceleration, also angular velocity and acceleration. The conclusion of this research is analysis of the best movement pattern to perform smash in badminton athletes can be conducted by analyzing the translational and angular curves. Those curves obtained by using the cubic spline interpolation approach for position coordinates in three dimensional space.
