CONTEXTUAL TEACHING AND LEARNING UNTUK MENINGKATKAN KEMAMPUAN PEMAHAMAN KONSEP PECAHAN
No full textOne of the basic abilities in learning mathematics is the ability of students to understand mathematics. Mathematical comprehension ability will develop other mathematical abilities, including communication, connection and problem-solving abilities. To be able to hone students 'mathematical abilities, a learning model is needed that is appropriate to the students' character and the material being taught. One learning model that can improve student learning outcomes is the Contextual Teaching and Learning (CTL) model. The method used in this study is Classroom Action Research (CAR). Subjects in this study were fifth grade in Elementary School. The instruments used in this study were tests and observation sheets of teacher and student activities. Based on the analysis of research data, it is concluded that CTL can improve the ability of mathematical understanding of fraction concept for elementary students. Thus, the use of CTL learning models can be used as an alternative learning to be applied to learning mathematics in elementary school especially on learning concept of fractions

TINGKAT KREATIVITAS SLOW LEARNERS DALAM MEMECAHKAN MASALAH MATEMATIKA
No full textThe heterogeneity of students in Indonesia is a challenge for teachers today. Creativity is not only for students with high mathematical abilities, but also introduced to students who are in the slow learner category. This research is a qualitative descriptive study that aims to describe the level of creativity of the slow learner, and to describe how to develop creative thinking skills for slow learners. The subjects in this study from one of the schools in Yogyakarta whose students were included in the slow learner category. The subjects were selected by purposive sampling. Data collection had been done by giving problems solving to subjects, then interviewing them to clarify the answers that have been written. Data analysis had been stopped on the third subject because the data from the third subject was no difference with data from the previous subject. The results of this study indicate that slow learners are not able to show the three indicators of creativity in solving mathematical problems (fluency, flexibility, and novelty), so that the slow learners are classified as creative thinking skills level 0 or included in not creative students. Other findings indicate that one subject indicated being able to show one indicator of creativity, namely fluency, so that subject classified as level 1 (almost not creative)
PERBANDINGAN KEBIASAAN BERPIKIR DAN HASIL BELAJAR MATEMATIK ANTARA SISWA SANTRI DAN NON-SANTRI
No full textThis study aims to examine differences in mathematical habits of mind and mathematical learning outcomes between santri students and non-santri students. The design of this study is comparative research. The research data was collected by interviewing a mathematics teacher and spreading the scale of mathematical habits of mind. This research was conducted in two schools in Karawang precisely in Rawamerta. The schools used are private schools run by pesantren foundations for the sample of santri students and public schools as samples of non-santri students. From the results of data processing in the results obtained that there is no difference in mathematical habits of mind between santri students and non-santri students. In addition, there is no difference in mathematical learning outcomes between students of santri and non-santri. Meanwhile, there is an association between mathematical habits of mind and mathematical learning outcomes of students.This study aims to examine differences in mathematical habits of mind and mathematical learning outcomes between santri students and non-santri students.

LITERASI NUMERASI SISWA DALAM PEMECAHAN MASALAH TIDAK TERSTRUKTUR
No full textThis study aims to explore the numeracy literacy of students in ill-structured problem-solving on the matter of numbers. This study involved 34 students of the 4th grader in one Madrasah Ibtidaiyah in Bandung. The research approach used is qualitative with the case study method. The type of data collected is test results about ill structured problem-solving. The data were collected from tests, document analysis, and interviews. After that, the data were analysed using thematic analysis, while the validity of data using triangulation, member checking, and reflexivity. The results of the research showthat students' numeracy literacy in ill structured problem-solving are (1) students are able to solve ill structured problem in the context of daily life; (2) students are able to analyze the information obtained from the problem then use the interpretation analysis to predict and draw conclusions. The difficulties experienced by students are (1) the difficulty in understanding the problem; (2) lack of students' understanding of the prerequisite material; (3) the difficulty in developing a settlement strategy; and (4) the difficulty in drawing conclusions
PENINGKATAN KEMAMPUAN GURU DALAM MENGEMBANGKAN RANCANGAN PERMASALAHAN MATEMATIKA DITINJAU DARI LEVEL KEMAMPUAN BERPIKIR SISWA
No full textThe ability of a teacher to design mathematical problems affects the characteristics and quality of mathematics learning that teachers do in class. Therefore, teachers need to have insight into how to design problems to encourage certain students' thinking skills. This study aims to describe improvement in teacher's ability to design mathematics problems before and after discussion activities designed by researchers. The method used is qualitative descriptive with the subject of seven junior high school mathematics teachers. Based on the results of this study it was found that after participating in the discussion activities, the number of teachers who designed problems that could encourage the level of thinking ability to apply decreased by 28.57%, the level of evaluation increased by 21.43%, the level analyzed remained, and the level of understanding increased by 7.14%. From 28 problems that have been designed both before and after the discussion activities, it is found that 10.71% is a matter that drives the level of understanding, 50% encourages the level of application, 17.86% encourages the level of analysis and 21.43% encourages the level to evaluate
SIKAP SISWA TERHADAP PEMBELAJARAN GEOMETRI MELALUI MODEL PACE BERBANTUAN GEOGEBRA
No full textThe aim of this study is to look at students' attitudes towards Geometry learning through the PACE model assisted by GeoGebra in one of junior high school in Cimahi City. The method used in this study is descriptive qualitative with a one-shoot case study design. After students taught during Geometry learning, namely by using the PACE model assisted by GeoGebra, at the end of the learning students are given a Likert model attitude scale questionnaire containing 21 statements with four choices. The results showed that students' attitudes towards the five indicators measured all showed positive attitudes. The attitude shown by the students' answers to the proposed statements shows the positive attitude of students towards interest, seriousness, and pleasure during Geometry learning through the GeoGebra-assisted PACE model.The aim of this study is to look at students' attitudes towards Geometry learning through the PACE model assisted by GeoGebra in one of junior high school in Cimahi City.

SPEKTRUM SYMBOL DAN STRUCTURE SENSE MATEMATIKA SISWA MADRASAH TSANAWIYAH
No full textThe purpose of this study is to determine the symbol sense and structure of mathematical sense in terms of students' ability to solve algebraic problems or other mathematical problems that require symbol expression or structure. Difficulties experienced by students in solving mathematical or algebraic problems may be due to the ability of symbol sense and low structure sense or didactic design that the teacher conveyed is not in accordance with the category of symbols and structure sense that students have. A student with good symbols and structure sense is able to appreciate the power of symbols, knowing when to use the right symbols and being able to manipulate and understand symbols in various contexts. The method used in the study used a qualitative descriptive method. The population of this study was seventh grade students of the Islamic junior high school, the instruments used were symbol and structure sense tests, questionnaires, and interview forms. The results of the study indicate that the ability of symbol sense and student structure sense is still low because of a lack of conceptual knowledge and algebraic manipulation, for this reason it is necessary to have an appropriate learning model to improve both of these abilities
