Analisis Penguasaan Siswa Sekolah Menengah Atas pada Materi Geometri
Get PDFGeometry is one of the subjects studied at the high school level. Learning geometry includes the position, distance, and angle of the elements of a space. This study was a qualitative study aimed to look at the students' mastery of geometry. Subjects in this study were students in high schools in Banda Aceh were categorized in high school, medium, and low. Categories of student mastery of the geometry were analyzed based on mistakes made by students in answering the questions. Based on the data analysis it can be concluded that (i) high school students in Banda Aceh had not mastered geometry, (ii) there were mistakes made by students in answering the question of geometry. Mistakes made by students include misconceptions, operation, and analysis, (iii) the student mistakes caused by (1) not mastered the concepts, (2) inability to perform the operation, and (3) not able to perform the analysis in accordance with the expected completion problem. Important information obtained through this study was that the mistakes made by students in solving geometry had a close connection with the student's mastery of geometry

Pengaruh Pembelajaran Contextual Teaching Learning (CTL) terhadap Kemampuan Koneksi Matematis Siswa SMP Ditinjau dari Gender
Get PDFContextual Teaching Learning (CTL) is a learning approach that can help teachers relate learning materials with students real-world situations and encourage them to make connections between their knowledge by the application in their life as members of the family and society. Mathematical connection ability includes finding the relationships between mathematics and its topics, mathematics and other subjects, and mathematics and daily life or the real world. The purposes of this study were (1) to know the difference in students mathematical connection ability before and after using CTL, (2) to know the difference in mathematical connection ability between male and female students, and (3) to know the effect of CTL on mathematical connection ability of VIII grade students of Junior High School in terms of gender. This study adopted a factorial design, a modified version of true experimental design. The subjects of the study were 34 students of class VIII-4 of SMP Negeri 3 Banda Aceh as experimental class without control class. The instrument of data collection was mathematical connection test. Data were analyzed using Analysis of Variance (ANOVA). The finding of the study shows that (1) there was a difference in students mathematical connection ability before and after using CTL, (2) there was no difference in mathematical connection ability between male and female students, and (3) there was a learning effect of CTL on mathematical connection ability of VIII grade students of Junior High School in terms of gender. The implications of this study demonstrate that learning mathematics with CTL approach was one of the efforts of teachers in teaching and learning activities in particular mathematics courses to improve male and female students' connection ability
Peningkatan Kemampuan Komunikasi dan Penalaran Matematis Siswa Madrasah Aliyah melalui Model Pembelajaran Kooperatif Tipe
Get PDFAbstract. 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, Reasonin

Pengebangan Design Pembelajaran Tematik untuk Meningkatkan Pemahaman Konsep Bilangan Desimal Siswa Sekolah Dasar
Get PDFAbstract: The decimal number is a subject matter that is difficult to understand by elementary school student. Fractions and decimals is seen by the student as two different things. Students are difficult to understand that 1/4 is equal to 0.25 for the different way of writing. This condition causes the teachers need to design learning trajectory that can facilitate students to understand the decimals material. The purpose of this study was to develop a Hypothetical Learning Trajectory (HLT) that can help students understand the concept of decimal numbers. This study involves a teacher and 36 students of fourth grade of elementary school in Banda Aceh. The method used was a design research method that was done by using two cycles they are pilot experiments and teaching experiments. Each of them consists of three stages: (i) preparing for the experiment, (ii) the teaching experiment, and (iii) the retrospective analysis. Research data collection using two kinds of instruments that were the main instrument who was the researcher's herself and supporting instruments consisting of student activity sheets, observation sheets, interview, and field notes. The results showed HLT that was developed can help students understand the concept of a decimal number.Keywords: Hypothetical learning trajectory, conceptual understanding, decimal number

Get PDFMathematical 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
