Abstract

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.

Abstract

This study aims to determine the mathematical critical thinking ability of junior high school students in Rancabali District with indicators of the mathematical critical thinking ability of students used to understand the problem, provide arguments, induce and the ability to make decisions or actions. The ability of mathematical critical thinking is the ability to think that aims to make decisions or actions that make sense through what is believed to be truth and can be done correctly. This research was conducted on 10 students in one junior high school in Rancabali District by using a qualitative descriptive method. The instrument used in the form of 4 items about students' mathematical critical thinking skills on the material to build flat side spaces accompanied by interviews with students. The conclusion of this study is the mathematical critical thinking ability of junior high school students in Rancabali District is still very low.

Abstract

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

Abstract

The study was conducted to analyze the relationship of learning motivation to the mathematical problem solving ability of 7th grade students. The research method is correlation. The research subjects consisted of 32 7th grade students at SMPN 3 Purwakarta. Test test instruments and non-test instruments are the methods used in data collection. The test given was in the form of 5 problem solving abilities in the form of essays and non-learning motivation scale with Likert scale. The normality test, the correlation test, the determinant coefficient, the significance test to see the correlation between the variables of learning motivation and the variables of mathematical problem solving ability are the steps taken. The conclusion from the results of the study there are 12.18% the relationship between learning motivation and problem solving abilities of junior high school students.

Abstract

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.

Abstract

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.
