PENERAPAN SOFTWARE GEOGEBRA DALAM MATERI SEGITIGA DAN SEGIEMPAT UNTUK MENINGKATKAN KEMAMPUAN KOMUNIKASI MATEMATIK SISWA SMP

This study aims to determine the effect of GeoGebra software on junior high school students' mathematical communication skills. The method used is the quasi-experimental method. This research was conducted at Pasundan Rongga Middle School. With class VIII A as an experimental class with 28 students and class VIII C as a control class with 28 students. This study uses instruments that have been tested and declared valid and reliable. The instrument was adjusted to the indicator of mathematical communication skills with the number of questions tested as many as 5 questions to obtain pretest and posttest data in both the experimental class and the control class. Data testing is done using normalized n-gain formula so that the n-gain data obtained is processed using the SPSS 20 application to perform parametric statistical tests. The results showed that the mathematical communication skills of students who learned using GeoGebra software were better than students who learned without using GeoGebra software.

ANALISIS SELF CONFIDENCE SISWA KELAS X HT 3 SMK SANGKURIANG 2 DALAM PEMBELAJARAN MATEMATIKA

SMA/SMK was the last high school before going to College. High school students/CMS are at the stages of adolescent age. The World Health Organization (1974) set the age limit of 10-20 years as a teenage limit (Sarwono,2008). Based on a review of the theory of progression, the age of adolescence is a time of onset of rapid changes, such as physical changes, changes in fundamental aspects of cognitive, emotion, social and achievement. Teens experiencing instability from time to time and they try to adopt new behavior from the previous development phases (Soetjiningsih,2004). Teens often have problems because of her unstable and still has not been formed in cooked. The attitude of the labile affected the level of confidence, such as the fearless try and there are times when his minder with her own.

ANALISIS KEMAMPUAN BERPIKIR KRITIS MATEMATIS SISWA SMP PADA MATERI LINGKARAN DAN BANGUN RUANG SISI DATAR

The skill to think critically and mathematics is the basic essential mathematic skills and need to owned by students who study math. This research method use qualitative descriptive research which aims to analyze the student’s mistakes when they do mathematic critical thinking questions on the discussion of circle and flat side geometry. This research subject is 8th grade student who study at one of public junior high school in the city of Purwakarta, Indonesia. The test instrument was 5 essay questions. The research result show that more students have their own difficulties when they do question number 2,3 and 5. I suggested the learning strategy which can upgrade their mathematics critical thinking skill should be used as the learning process.

MENINGKATKAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIK SISWA MA DENGAN MENGGUNAKAN PENDEKATAN OPEN ENDED

This research is based on the problem of the low mathematical problem solving ability of students who have a relationship with someone's success in solving a problem that they face. In this case, to overcome this, a class of research was conducted using an open ended approach and ordinary learning. In addition, this research is a quasi-experimental. The population in this study were students of class X MA in Bandung in 2018/2019 academic year. The research sample is all Class X students in one MA in Bandung. Quantitative analysis was performed using the two-difference test and descriptive qualitative analysis was also carried out. The results showed that the ability to solve mathematical problems using the open ended approach was better than those using the usual approach.

PENERAPAN PENDEKATAN PROBLEM BASED LEARNING UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS SISWA SMP

This research aims to finding out and study the achievement and improvement off critical thinking skill off junior high school student with Problem Based Learning approach and using ordinary approach. The method used is an experimental method that involves two classes chosen at random selected classes i.e. VII A class using the Problem Baseed Learning and class VII B using a regular learning approach. The instrumen using is critical thingking skill. The results test analysis of postes data the value sig (2-tailed) is 0.002, while the test results of the difference of two average data gain, sig value (2-tailed) is 0.003. The findings in this studi were the achievement and improvement of the mathematical critical thinking skills of junior hiigh school students using the Problem Based Learning better than those using the usual approach

MENINGKATKAN KEMAMPUAN PEMAHAMAN KONSEP MATEMATIK SISWA SMP DENGAN PENDEKATAN KONTEKSTUAL

This investigate is motivated by the low ability to comprehend the mathematical concepts of SMP students in KBB, so a learning approach is needed to decipher these problems. Alternative approaches are applied, namely the contextual approach. The method make use of in this investigate is an experimental method with a control group design pretest posttest. The population in this research were all junior high schools in KBB while the school sample was Kahuripan Lembang Middle School which was chosen based on school randomization. Sample class were taken randomly from the 4 classes of class 7 of Kahuripan Lembang Middle School, class 7-2 as the tentative class and class 7-4 as the control class. The tentative class uses contextual learning while the ordinary learning control class. The reason for taking class VII is because with deliberation in the semester one there are topics in the Triangle and Quadrangle that will be used in the study. The instrument in this investigation was a package of five test questions. The researcher can conclude that the achievement and repair of the capability of understanding The mathematical concept of SMP students who use a contextual approach is better than those using ordinary learning.

PENGARUH MODEL PEMBELAJARAN SNOWBALL THROWING TERHADAP HASIL BELAJAR SISWA

This study aims to examine student learning outcomes using the type of snowball throwing learning towards student learning outcomes in mathematics subjects at MTs Islam Al-Maziyyah cianjur. The use of the method in this study is quasi-experimental with pretest and posttest equivalent to the control group design. Students of class VII Islamic MTs Al-Maziyyah cianjur which amounted to 3 classes were used as the population for this study while the research sample was class VII A as an experimental class that was treated with snowball throwing learning and VII C as a control class received normal learning treatment. The research instrument was in the form of student training experiments.
