<![CDATA[The ability to understand mathematics is a basic ability that must be improved because there are still many students who have low understanding abilities. Kahoot learning media can improve students' mathematical understanding abilities according to the material and student characteristics. The purpose of this study is to determine the success of applying Kahoot media in improving the ability to understand mathematics in integer material for junior high school students. The method used in this research is quantitative. The data collection technique comes from the results of a description test of 4 questions regarding students' mathematical understanding abilities in integer material. Quantitative data analysis techniques were processed using descriptive and inferential statistics using Microsoft Excel and SPSS applications. This research was conducted on students at one of the MTs in West Bandung class VII as many as 22 students. The results showed that there was an increase in students' mathematical understanding abilities as indicated by the learning outcomes and student responses after the learning process took place. Students can develop their mathematical understanding skills with the help of this Kahoot media. This increase can be proven by the increase in students' pre-test and post-test results as evidenced by the calculation of the n-gain value. The results of the n-gain calculation show that the increase in students is 0.83 in the high category. This means that the application of kahoot media is successful in increasing students' mathematical understanding of integer material.]]>

<![CDATA[The low ability of students' mathematical communication in learning mathematics, especially in expressing mathematical situations or problems in the form of pictures, diagrams, language or mathematical symbols, or mathematical models makes students less active in learning and their learning motivation decreases. This study aims to determine the achievement of students' mathematical communication skills through the discovery learning model with a window shopping approach. The method in this study is a quasi-experimental research type consisting of 2 classes, namely the experimental class that uses the discovery learning model with the window shopping approach and the control class that uses ordinary learning at school with a total of 70 students from class XI SMA in one of the public high schools in Bandung. The research test instrument was in the form of a test that would be analyzed using SPSS 21 to compare learning outcomes between the experimental class and the control class. The result of the study was that the achievement of the students' mathematical communication skills in the experimental class was better than that of the control class at a significance level of 0.05 where the average communication ability of the experimental class was 81.74 and that of the control class was 77.31. The effectiveness of learning in the experimental class showed that it was more active in group discussions as indicated by the interaction and creativity of students in presenting learning material in each group, and almost 85% of students enjoyed learning using the discovery learning model with the window shopping approach.]]>

<![CDATA[Essay test questions in mathematics learning at Vocational High Schools show that most students have difficulty answering questions about quadratic equations, this is the basis of the research. The reason this problem can occur is because students are not careful in interpreting questions so students cannot master inductive indicators. The purpose of this study is to find out more about students' mistakes when answering questions about mathematics through analysis and description of some of the students' mistakes in answering questions about quadratic equations, therefore this study uses a descriptive method with a qualitative approach. The research subjects were students of class XI Software Engineering at a Vocational High School in Kabupaten Bandung Barat with a total of 15 students. The stages in this research are planning, implementation, and reporting. Student test results as many as three questions are used to collect data. The analysis technique used is data reduction, by presenting the data then conclusions are drawn. The results and discussion of this study showed that students made mistakes in answering quadratic equation questions. The accuracy of students towards questions number 1 and number 3 is still low, so it is necessary to do regular exercises. Students' mathematical reasoning abilities need to be honed again. It can be seen from the results of the answers to question 2 that students have not been able to interpret the questions so that inductive indicators on students' mathematical reasoning abilities have not been fulfilled.]]>

<![CDATA[This study aims to find out how well vocational students solve mathematical problems based on the composition function material. Mathematical problem solving ability is an ability that must be mastered by students because this ability is the core of mathematics. The location of this research is at SMK TI Garuda Nusantara and the main object of research is class XI students totaling 32 people in one class. The author used a descriptive qualitative approach. Several test questions were used as data collection methods. of 32 students in one class. It can be said that only 9 people were able to complete the test questions and get a good rating on each indicator. The results show that the problem solving ability of students in class XI of SMK TI Garuda Nusantara is classified as sufficient or moderate. This is very clear from the fact that only 28% of students who achieved perfect scores in the good category. 56% were rated medium, and 16% were rated low. The acquisition of the highest indicator value is in problem solving ability, while the lowest indicator is in the indicator of understanding the problem, this is due to the lack of understanding of basic mathematical concepts in students. In order for students' problem-solving skills to improve, researchers suggest that further research should use learning models or media that can help students understand mathematical concepts.]]>

<![CDATA[Students have difficultly solving problem in question such as when solving word problrms, asking questions, making steps to solve, and solving problems given. Problem solving skills are a very important part of mathematics curriculum. So the researchers conducted a study that aimed to determine the effect of problem based learning models on problem solving abilities in class VII set material. The development model used is an experimental research type using a quantitative approach. The research data was obtained trough test instruments or scores from the problem solving instrument on set material. Data analysis of problem solving abilities was carried out using the t-test. The subjects of this study were 78 students. The sample was taken by simple random sampling, selected class VII D with a total 10 students as the experimental classs and 10 from class VII E as the control class. The results of this study indicate thet the problem based learning model has an effect on problem solving abilities. This can be seen based on the results of working on essay test question based on students problem solving abilities which get a tcount of 2.5776 while the ttable value is 2.0378. This means that the value of tcount is greater than t table, so in this case it means that H1 is accepted, meaning that there are differences in mathematical problem solving abilities between the experimental class and the control class. This shows that the problem based learning model has an influence on problem solving abilities.]]>
