<![CDATA[Facts on the field show that there are still many students who have low abilities in solving mathematical problems. One of the factors that influence this is because students are not accustomed to practicing solving math problems in class. The questions given to students were only questions that put more emphasis on carrying out procedures and calculations. The research was carried out to obtain an overview of students' mathematical problem solving abilities. The research in question was carried out at the end of elementary school level and at the beginning of junior high school level. It is hoped that the results of this research can be used as material for consideration and input for improvements and changes in the learning process to improve students' mathematical problem solving abilities. This study uses a qualitative approach. While this type of research is a phenomenological study. Phenomenology is a study that describes what a person receives, feels and knows in his consciousness about the experiences he has experienced. And what emerges from that awareness is called a phenomenon. The subjects of this study were students of class VI elementary school and class VII junior high school. Based on the results of the research and discussion, it can be concluded that there are similarities and differences in the characteristics of problem solving abilities between students at the final level of the elementary school level and students at the initial level of the junior high school level.]]>

<![CDATA[There are various types of thinking skills that can be developed by studying mathematics, one of which is the algebraic thinking skills. One of the abilities in algebraic thinking is quantitative reasoning ability. Quantitative reasoning ability is a fundamental ability for students to be successful in learning mathematics. However, the facts on the field show that there are still many students who have low mathematical reasoning abilities. The purpose of this study was to obtain an overview and characteristics of students' mathematical reasoning abilities, especially students' quantitative reasoning. This research uses a qualitative approach, while this type of research is a phenomenological study. Phenomenology is the study that describes what a person receives, feels and knows in his consciousness about the experiences he has experienced. The subjects of this study were students of class VI elementary school and class VII junior high school. Based on the results of the research and discussion, it can be concluded that there are similarities and differences in the characteristics of quantitative reasoning between students at the final level of elementary school and students at the initial level of junior high school.]]>

<![CDATA[The National Assessment has been carried out simultaneously in Indonesia, but there are still many who do not fully understand the nature of the AN itself. The lack of socialization means that there are still many teachers who experience difficulties in preparing and implementing AN. The same thing was experienced by teachers at SDI Buraen 2, Kupang Regency, and NTT. The service activity aims to socialize the National Assessment with teachers at SDI Buraen 2, especially about one form of evaluation in the AN, namely the character survey. This activity was carried out in three stages: workshops, mentoring, and evaluation. Based on the evaluation results, it was found that this service activity had provided benefits, including: 1) adding insight and understanding to teachers about AN, especially regarding character surveys. 2) The school succeeded in designing school activities that are useful for instilling the characters in the profiles of Pancasila students. 3) Add to the experience of students in dealing with character surveys. Students begin to get to know the situation in the character survey and the questions in the character survey.]]>

<![CDATA[Most students dislike studying mathematics because they believe it contains much difficult material. Algebra is one of the topics considered difficult to learn in mathematics. The teaching material used is one factor that influences the low mastery of material in algebraic language. This research aims to develop valid teaching material using the Mind Mapping mode for algebraic topics. The modules and leaflets of the students' activities are the materials made. This research refers to the Kemp model, which consists of 10 stages of development. However, the scope of this research is only from the need analysis stage to the validation stage. Device validation sheets are used as data collection tools. This research uses qualitative and quantitative data analysis methods. Three people - a lecturer, a teacher, and a ninth-grade student - validate the teaching material that has been made. The results of the validation stage show that the teaching material is declared valid with little revision. The results of this study show that the teaching material is ready to be implemented.]]>
