This study aims to find out in depth about how much influence gender has on the mathematical creative thinking ability of junior high school students who have previously received the Realistic Mathematical Education (RME) learning approach. The method in this study uses quantitative secondary data analysis methods. The data collection technique used is documentation. Documentation is taken from a thesis that has a relevant topic/title with the same purpose. While the data analysis used in this study is the Covariance Analysis test (Ancova). The Ancova test aims to see how much gender influences the ability to think creatively in mathematics, while before the Ancova test is carried out, prerequisite tests are carried out, namely the Normality test and Homogeneity Test. The results of this study indicate that there is no influence of gender on students' creative thinking abilities. The value of the R Squared Multiple Determination Coefficient obtained is 0.041, which means 4.1% of the achievement of students' creative thinking abilities is influenced by gender factors. The remaining 95.9% is influenced by other factors, one of which is the RME learning approach carried out by previous researchers. So it can be said that the gender factor does not have a major influence on the achievement of students' mathematical creative thinking skills in the mathematics learning carried out.

This research is based on the low level of students completing PISA questions. One of the factors that influence the low number of students in PISA questions is that they are not used to working on problems in real context. The purpose of this study is to describe students' mistakes in solving PISA questions on Space and Shape content based on Newman's Theory, namely: reading errors, misunderstanding, transformation errors, process skill errors and notation errors or writing answers. This study uses descriptive qualitative data collection in the form of images and sentences described. The subjects in this study were eighth grade students of SMP Negeri 9 in Cimahi City. Data collection techniques in this study are by giving a test in the form of PISA questions on Space and Shape content in 2012. Based on the results of the study, showed that students experience errors in process skills caused by the lack of PISA practice exercises which are international assessments, as well as students' weakness in skills mathematics in the form of real contexts.

Mathematics learning aims to train students to observe, think, and express the real world with mathematical vision. However, in the traditional static concept teaching mode, teachers tend to use the concept formation or expository method, so most students cannot understand abstract concepts in class but have to do exercises to consolidate their understanding of concepts, which does not meet the requirements of cultivating talents with core mathematical literacy. Literature research method: To understand the current research status of APOS theory on mathematics concept teaching at home and abroad, this study consulted relevant books, journals, papers, and network resources at home and abroad. This paper discusses it based on the history of mathematics and provides practical guidance for teachers on designing student-centered teaching activities based on APOS theory. Based on the teaching design under the APOS theory, problem-solving is used to gradually guide students to abstract mathematical concepts and learn to think about the real world with mathematical thinking. Teachers will also diagnose students' learning stages through problem-solving situations and constantly debug math classes suitable for students. In guiding students to think, explore and interact, teachers create cognitive conflicts many times, encourage students to question questions, and give full play to students' subjectivity.

The theory of rethinking teaching originated from the European and American countries, and then it was paid attention to gradually in our country. Reflective teaching theory is an important means to enhance teachers' thinking ability and students' learning ability and improve teaching quality. Based on the overview of reflective teaching theory and its teaching strategies, the author discusses the teaching practice of reflective teaching theory in the middle school mathematics proposition lesson of the same triangle decision lesson, in order to provide reference for improving teachers' professional quality and students’ learning ability.

This study aims to describe the process of solving mathematical problems in the subjects of a two-variable linear equation system in terms of field-dependent cognitive style. The type of research used is descriptive qualitative research. The research subjects were 15 grade VIII students in one of the public junior high schools in Cimahi City. In this study, the instrument used was a problem-solving test consisting of 2 questions on the material of a two-variable linear equation system and interviews for 3 students with field dependent cognitive style. The results showed that the steps of solving mathematical problems of students with cognitive style field dependent were categorized as good at the stage of understanding the problem and re-examining, categorized enough at the stage of planning completion, and categorized less at the stage of implementing the completion plan. This means, if field dependent students can understand the problem or problem, it will affect the next step.
