This research is development research. This study aims to develop VBA Powerpoint based learning media on SPLDV material for class VIII junior high school students. Samples for this research are taken from one of junior high school in Bandung. This study refers to the ADDIE development model which includes five stages, namely: Analysis (Analysis Phase), Design (Design Phase), Development (Development Phase), Implementation (Implementation Phase), and Evaluation (Evaluation Phase). The instrument of this research is in the form of assessment sheets for material experts, media experts, teachers and students. Based on the analysis of learning media through the instruments given to material experts, media experts, teacher and students obtained the following results, material experts stated that the product was very valid with an average value of 3.64 and media experts stated that the product was valid with an average value of 3.06. While the results of teacher responses can be concluded that the product is very valid with an average value of 3.50 and from the results of student responses can be concluded that the product is valid with an average value of 3.18.1

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.

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 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.

AbstractThis 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.

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.

This study was conducted to analyze the learning interest of class VIII MTs students in mathematical learning through Geogebra application. The research method used descriptive qualitative with a population of all MTs students in West Bandung Regency. The sample used was 28 students of class VIII-A MTs Al-Barry. The instrument used is the Learning Interest Scale with 20 statements that have positive and negative responses about learning using the Geogebra application. The learning interest scale is used to look for responses from respondents to the learning interest of junior / MTs students in statistical material whose learning uses Geogebra applications. The results of this study indicate that students' interest in learning in statistical material with Geogebra application media shows positive results with average responses showing a strong category with a percentage of 69,46%. The average is obtained from data on each indicator of student learning interest.

This study is aimed at analyzing students' mathematical communication skills based on the results of observations, namely the ability of junior high school students. Subjects consisted of 20 students with categories using high, medium, and low grades. The method used is the Problem Based Learning approach. Data obtained from student results because of student tests and how students in finding mathematical communication solutions students who can solve problems and can solve mathematical problems well. But few students can solve problems because students perceive that mathematics learning is very difficult, especially mathematics communication material. After the treatment of Problem Based Learning, children's results are better than classes that use normal learning. With the increase in the authors concluded that the Problem Based Learning approach can be further investigated with a lot of practice. researchers hope that the Problem Based Learning approach can add insight to students.
