<![CDATA[AbstractThis research is based on the problem of the low mathematical problem solving ability of students who have a relationship with someone's success in solving a problem that they face. In this case, to overcome this, a class of research was conducted using an open ended approach and ordinary learning. In addition, this research is a quasi-experimental. The population in this study were students of class X MA in Bandung in 2018/2019 academic year. The research sample is all Class X students in one MA in Bandung. Quantitative analysis was performed using the two-difference test and descriptive qualitative analysis was also carried out. The results showed that the ability to solve mathematical problems using the open ended approach was better than those using the usual approach.]]>

<![CDATA[The ability to master concepts is one of the obstacles experiences by students in studying algebraic form. This is the background of the author to conduct this research with the aim of knowing the increase in students conceptual mastery if a contextual approach is applied to learning algebraic form in class VII Junior High School of Dharma Kartini Cimahi. The type of research used is Classroom Action Research (CAS) with the methods use are survey, test, and observation methods, the analysis used is qualitative. The results of the stude are evidenced by the improvement in student learning outcomes from the condition of learning completeness that no one reaches the KKM value, increasing in the first cycle as many as 8 students (40%) and in the second cycle it has increased to 15 students (75%). It can be concluded that the application of the contectual approach is good enough to improve students mastery of concepts in algebraic form. ]]>

<![CDATA[This study aims to identify and describe the results of the errors that students experience in the process of solving problems of comparative story problems. The researchers applies a qualitative descriptive methods when conducting his research. The subjects of this study were students of class VII-A of SMP Negeri 8 Cimahi, a total of 24 students. The data collection technique used has three stages: (a) data reduction, (b) data presentation, (c) drawing conclusions and using help tables in order to determine the percentage level of error. The instrument used is in the form of a description of 5 test questions. The results of student work were analyzed based on the Newman procedure. Based on the results of the study, the highest percentage of errors was found in the average process skill error, which was 33.3%, while the lowest error was found in the average percentage of reading errors, which was 5.8%.]]>

<![CDATA[This research was conducted at SMP Pembangunan 1 Baleendah students of class VII researchers using the discovery learning model aimed at improving students' learning outcomes in set materials. The type of research used class action research conducted in the II cycle method used is descriptive qualitative. The material used in the form of , in this class action research researcher only focuses on student learning outcomes because the lack of learning outcomes affects the learning process therefore researchers use II, aiming to see results before and after being given video or ICT assistance with discovery learning. In cycle I class action research students gain small grades and understand the material due to too long online learning makes students become lazy in learning, cycle II experiencing an increase in learning outcomes by using the help of video or ICT students eagerly back in learning. Thus, the study of class actions conducted in Junior High School Development Works 1 Baleendah class VII students using the discovery learning learning model is divided into II cycles with the help of providing video in the form of set summary material resulting in changes in student learning outcomes for the better, therefore the provision of video or ict affects learning outcomes.]]>

<![CDATA[The ability to solve problems is one of the abilities that students need to have in learning mathematics. Especially solving stories or non-routine questions, students really need to have the ability to solve these problems. Therefore, this study aims to determine and examine the ability to solve mathematical problems in solving one-variable linear equation (PLSV) material stories in junior high school students conducted in one of the public junior high schools in the city of Cimahi. This research method uses a qualitative descriptive method. The subjects of this study were 15 grade VII junior high school students and the data obtained by testing 4 written tests in the form of stories related to everyday life which refers to the steps of problem solving skills, namely finding mathematics from data, making mathematical models from problems. story, planning a settlement strategy, checking the correctness of the answer. From the results of research that has been done that the problem-solving ability of students is still relatively low because students are not accustomed to working on the form of story questions which causes students to find it difficult to determine the steps to be able to solve problems, formulate story questions into mathematical models.]]>

<![CDATA[Series and sequences one of the most important sub-topics in mathematics since students frequently make mistakes or forget formulae when solving problems, which has an impact on learning results. This study tries to explain how a discovery learning strategy at the vocational high school level improved student learning results in class X. This study is an example of classroom action research. The class X pupils at one of the Cimahi Vocational High Schools served as the study's subjects to determine whether the instructor has a direct impact on the learning process. With the Discovery learning strategy, this project seeks to enhance students mathematics learning results. According to the analysis of learning outcomes and completeness scores, cycle I students mathematics learning outcomes demonstrated a moderate level of material mastery with only 33% of students completing them, whereas cycle II students' mathematics learning outcomes demonstrated a high level of material mastery with 75% of students completing them. The class X SMK's mathematics learning outcomes can be enhanced by the discovery learning technique.]]>

<![CDATA[Covid-19 is a rapidly growing outbreak around the world, one of the obvious impacts is the education sector. Inadequate education affects the learning outcomes of learners. One of the factors that affect student learning outcomes is the presence of motivation that comes from the student itself. Without the willingness to learn, it can be difficult for students to know what to learn and why they need to learn it. The research used is correlational and ex-post facto research using quantitative approaches that aim to find out whether students' learning outcomes in statistical material have an effect on learning motivation. The subjects used in the study were class IX students consisting of 6 students including 3 women and 3 men. Research instruments conducted using student motivation scale questionnaires and written tests of statistical material. The data analysis technique used in this study is a simple linear regression analysis using an average percentage of motivational indicators and spsss statistic 25 software. The results of the study proved that there was an influence of 62.2% between learning motivation and student learning outcomes.]]>

<![CDATA[The purpose of this study was to analyze the Techno mathematics Literacy of non-Mathematics Education Teacher Candidate students in the Research Statistics course. This research is a qualitative descriptive study. The research subjects were 100 non-Mathematics Education students who taught the Research Statistics Course in the Odd Semester of the 2022/2023 Academic Year. Data on learning activities were obtained from the implementation of learning using observation guidelines and data on learning evaluation were obtained from learning evaluation activities based on tests of students' mathematical literacy abilities in the form of document studies, response questionnaires and interview sheets. Based on the results of the study, it can be concluded that the average ability of Techno Mathematics Literacy in the aspects of data literacy, Sense of errors and sense of numbers, and Creative aspects and ability to draw is included in the poor category, while the ability to use computer software and aspects of communication skills are in the Adequate category. Overall, the average Techno Mathematics Literacy of non-Mathematics Education prospective teacher students at IKIP Siliwangi is in the poor category.]]>
