No full textThis study aims to determine the mathematical understanding of students of class X of SMA Muhammadiyah 4 Surabaya. From the result of the test, it is known that the mathematical understanding of class X IPA of SMA Muhammadiyah 4 Surabaya is low. To overcome this, applied treffinger learning model with software sparkol videoscribe. The research method used is a Class Action Research (PTK) with a collaborative pattern. From this study, it can be seen that there is an average increase from 48,62 (low) to 80,34 (good). In addition, it can be known that the ability to reiterate the concept learned has increased from 58.62% to 72.41%; Ability to apply the concept algorithmically increased from 41.38% to 86.21%; Ability to give examples and counter-example of the concepts studied increased from 20.69% to 58.62%; Ability to present concepts in various forms mathematical representation increased from 10.34% to 79.31%; and Ability to link various concepts (internal and external mathematics) increased from 0% to 24.14%. Based on the findings in this study, the treffinger learning model using the software sparkol videoscribe can be used as an alternative to improve students' mathematical understanding.This study aims to determine the mathematical understanding of students of class X of SMA Muhammadiyah 4 Surabaya.

PENGEMBANGAN BAHAN AJAR MATERI INDUKSI MATEMATIKA DAN TEORI BINOMIAL BERBASIS PEMBUKTIAN
Full text linkStudents' ability in solving argumentation in mathematical induction and binomial theory is still lacking based on the results of the exam, so that evidence-based teaching materials are prepared. This study uses design research methods with the subject from 2nd semester students of the Mathematics Education Study Program. This research is a development research consisting of 6 stages: Identification of needs, Planning, Initial product development, Initial product testing, Product revision, Field trials so as to produce teaching materials. The results of the lecturer and student validation show that the teaching materials are valid and feasible to use with an average score of 45 and 45,9333. While the test of the effectiveness of teaching materials used using the t-test obtained results that ttest> ttable, 5.83 > 2.11 which means there is an increase in the average value of students before and after using teaching materials. With the increase in value, it indicates that the instructional materials prepared are effectively used
TINGKAT KREATIVITAS SLOW LEARNERS DALAM MEMECAHKAN MASALAH MATEMATIKA
Full text linkThe 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)

PENINGKATAN KEMAMPUAN GURU DALAM MENGEMBANGKAN RANCANGAN PERMASALAHAN MATEMATIKA DITINJAU DARI LEVEL KEMAMPUAN BERPIKIR SISWA
Full text linkThe 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
PERBANDINGAN KEBIASAAN BERPIKIR DAN HASIL BELAJAR MATEMATIK ANTARA SISWA SANTRI DAN NON-SANTRI
Full text linkThis 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.

CONTEXTUAL TEACHING AND LEARNING UNTUK MENINGKATKAN KEMAMPUAN PEMAHAMAN KONSEP PECAHAN
Full text linkOne 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
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.
