Abstract

The background of this research was that the mathematical critical thinking ability of the students is still low. Therefore, the purpose of this study was to find out the misconceptions or difficulties of students in each indicator of mathematical critical thinking ability of high school students that learned Brain Based Learning (BBL) with material in the Three Dimensions. This reseacrh used a qualitative approach with the  descriptive method. The subjects in this study were the students of XII MIPA 5 class or first grade of senior high school in Subang Regency which was on a total of 32 students. The instrument of this study consisted of a test instrument of mathematical critical thinking ability and a non-test instrument in the form of an observation sheet. The results of this study shows that students almost have difficulty in carrying out tests of mathematical critical thinking skills based on the indicators tested. The indicators of critical thinking ability tested include providing simple clarification (elementary clarification), making conclusion (inference), determining strategies and tactics (strategies and tactics) to solve problems, and making further clarification (advances clarification).

Abstract

This study aims to increase the mathematical communication skills of students at class VII A on rectangular flat material through the Think-Talk-Write (TTW) approach in SMP Negeri 11 Cimahi. This type of research is CAR or Classroom Action Research  using a model from Kemmis and McTaggart with spiral research, the population sample are all students of class VII A Cimahi 11 Public Middle School consisting of 36 students. This study to be composed of 3 cycles in which each cycle to be composed of the 3 stages that is planning, implementation, and observation reflection, before and after the study was given an instrument test in the form of a description test. In each cycle there is an activity observation sheet. The results of this study indicate that students' mathematical communication skills can be increase through the Think-Talk-Write (TTW) approach application.

Abstract

The learning process students must be trained to understand concepts well, not only memorize the material. Learning will be effective if students understand the mathematical concepts being studied. It was found learning difficulties especially in learning linear equations caused by a lack of understanding of the concepts and the way the teacher taught. The most common difficulties were in presenting mathematical concepts, understanding information about questions, and interpreting data in the design requested. Based on the problem, Author developed didactical design of two-variable linear equations material that aims to minimize the difficulties that occur. The research method used qualitative method that was Didactical Design Research (DDR). The subjects of the study were Bandung junior high school students, class VIII even semester who got the material of two-variable linear equations using Curriculum 2013. In general, didactical design implemented need to be maintained. Didactical design developed can minimize the obstacles of student learning difficulties. However, the researcher recommends the existence of a research on the development of didactical design of the concept of two-variable linear equations with various improvements, both in terms of deeper concepts, presentation, and predictions of student responses.

Abstract

Abstract This study aims to analyze and examine the mathematical communication ability that are influenced by junior high school students self-efficacy. The method in this study uses a correlational method with quantitative approach. The population in this study were students of junior high school in Cimahi City, with a sample of 36 students who were determined by purposive sampling technique at one of junior high school in Cimahi City. The instrument used in this study is a communication ability test that consisting of 5 essays and a students’ self-efficacy scale that consisting of 25 statements scales. The results showed that students communication ability was positively influenced by self-efficacy of 19.1%, while 80.9% was influenced by factors other than students’ self-efficacy. The correlation between self-efficacy and mathematical communication skills of students is included in the medium category. Keywords:  Mathematical Communication, Self-Efficacy

Abstract

This study was conducted under the action research method. It aims to analyse the role of scientific approach to Mathematical Critical Thinking (MCT) skills of high school students. This study was conducted in SMAN 22 Bandung and involved 31 students from grade XI Science 6 as participants and three essays of MCT test as the instruments. This study was conducted in three cycles. The researcher found that there was an improvement on the students’ MCT skills from cycle to cycle. The students encountered difficulties in solving problems related to identifying relevant and irrelevant data; hence, they did not encounter any difficulties in examining the validity of the process.
