<![CDATA[The purpose of this study was to determine the increase in creative thinking skills of junior high school students who use learning by using the problem posing approach and the scientific approach to classroom learning, especially in mathematics. Quasi experiment is this type of research with the control group pre test and post test design. The research was conducted at one of the junior high schools in Cimahi City. As many as 62 students of class VII being sampled in this study consisted of 30 students in the experimental class with problem posing learning and 32 students in the control class with scientific learning. The testing in this study uses IBM SPSS version 22 software. The conclusions from the results of this study are 1) Increasing the ability of mathematical creative thinking by using a problem posing approach better than the scientific approach, 2) A problem posing approach if it is well planned for effectiveness when learning takes place, and 3) Students who are inaccurate in solving the problem of the ability to think creatively because they do not understand the problems asked in the questions. This can be seen from several responses of students who are incomplete in giving responses]]>

<![CDATA[Mathematics is a science that can not be separated from other science as well as in everyday life. The ability of mathematical Connection aims to connect the mathematics with other disciplines and also daily life so that math can be more meaningful. This study aims to determine the ability of mathematical connections of junior high school students VIII class in one of junior high school in Bandung on Comparable material reviewed through gender. Subject consists of 35 students. In addition, the discussion on the mathematical connection ability for junior high school students from the difference of gender, between students and students in terms of ability penyimannya. The understanding of the mathematical connection capability rests on the concept of "socio-cultural construction" that there is a difference between men and women, resulting in their respective roles and duties. While based on the results of his research states that the difference of ability between male and female students and the results showed that the mathematical connection ability of female students is much better that is with an average of 3.71 from the students 3.59. In addition to gender factors are also found other factors that can affect the achievement of the ability of the connection of the readiness of students and teachers to learn, basic skills of students and basic knowledge of mathematical concepts]]>

<![CDATA[The use of important teaching materials in the implementation of learning. This research also aims to support mathematics learning to be more interactive and effective and to support student activities in the learning process to improve well. Student learning outcomes also focus on students’ mathematical critical thinking skills. Therefore, the purpose of this study was to determine the effectiveness of mathematic teaching materials on mathematical critical thinking skilss. The research method used in this study is experimental research, namely those obtained from observations, questionnaires and tests. The participants in this research were grade VI students of SMPN 2 Kertasari which consisted of 2 classes. The data analysis used in this research is descriptive analysis. The results of the study show three parts of effectiveness, namely the effectiveness of interaction showing 61% results with a moderately effective category, the effectiveness of understanding which shows 59% results in the moderately effective category and the effectiveness of teaching materials on mathematical critical thinking skills showing 62% results in the moderately effective category. Therefore, the use of mathematics teaching materials on mathematical critical thinking skills is quite good in its delivery and implementation.]]>

<![CDATA[The purpose of this study was to determine the extent to which students solve problems in mathematical understanding skills in statistics material. The method in this study is descriptive qualitative and data collection is given 3-point statistics questions in the form of descriptions. The research subjects were class VIII which amounted to 6 people. The results of the researcher's analysis show that mathematical understanding ability is still low in statistics material. Some of the difficulties experienced by students are that students still have difficulty reading the questions given, students' ability to understand the problem is still lacking, students' difficulty in writing the formula given, students' lack of accuracy in prerequisite material, students answer questions carelessly, so students do not solve the problem correctly. Difficulties in this study can be caused by students not paying attention to the teacher's explanation and even still lacking accuracy in understanding the problem, reading questions in the form of description questions, the way students think about mathematics comprehension skills is still difficult. Therefore, it is necessary to have an improvement and follow-up in future research to improve students' mathematical understanding ability in statistics material or better yet, it can replace other materials.]]>

<![CDATA[The ability to think critically is currently one of the abilities that students need to have because with the ability to think critically in students can improve the quality of education in Indonesia, with this statement this research was conducted with the aim of describing the critical thinking skills of junior high school students using a problem-based learning model on quadratic equation material. This type of research is in the form of descriptive research with qualitative methods. This research was located at SMPN 3 Cimahi with 9 subjects who had high, medium and low abilities in critical thinking covering 3 classes. The data collection technique was carried out by providing 4 description questions and interviews to the subjects. Data analysis techniques in research refer to qualitative data analysis according to Miles and Huberman. The results of the study were measured based on indicators of critical thinking skills according to Facion (2015) where, 67% of students were able to interpret, 58% of students were able to analyze, 72% of students were able to evaluate, and 69% of students were able to infer so that it could be concluded that there was a significant influence of the problem-based learning model on critical thinking skills.]]>
