2023-08-14T04:34:28+00:00

Communication skill is an ability that needs to be possessed by students. Through communication, students can express their opinions or ideas to their friends or to the teacher. The facts in the field show that students' mathematical communication skills are in the low category, therefore a solution is needed to improve students' mathematical communication skills. This research aims to produce problem-based learning-based LKPD assisted by liveworksheets to hone students' mathematical communication skills. This research was conducted at SMPN 1 Ngamprah. The subjects of this study amounted to 10 students on a limited trial. 34 students for a broad trial. The method used is development research according to Sugiyono which is modified into 7 stages carried out due to time constraints, namely: potential and problems, data collection, product design, design validation, design revision, product trial, and product revision. Data collection tools for this study are validation sheets, student response questionnaires, and 5 questions about mathematical communication skills in statistics material. Based on the results of value processing from validators, it shows that the developed LKPD is said to be suitable for use in learning, with an average percentage of assessment from validators of 85%. The results of the calculation of student answers show that the developed LKPD is effective for improving mathematical communication skills, with an average calculation of each indicator of 72.35%. It can be concluded that problem-based learning-based LKPD assisted by liveworksheets can be used in learning as an effort to improve students' mathematical abilities in statistics material.

2023-08-04T04:20:12+00:00

This research was motivated by the low mathematical problem solving ability of students based on the results of field observations and the results of previous research. This study aims to determine the effectiveness of LKPD assisted by live worksheets with a problem-based learning approach to the mathematical problem solving ability of grade VIII students. The method used in this study is an experimental method with One-Group Pretest-Posttest Design by Sugiyono. The subjects in this study were 30 grade VIII students at MTs Al-Firdaus with low, medium to high categories. The research instrument used in this study was in the form of five description questions adjusted to indicators of problem-solving ability which were then calculated using the SPSS application. Based on the calculation of the comparison of pre-test and post-test values, it is found that the post-test value is greater than the pre-test value. In the pre-test students still have some errors in working on the problems given, while during the post-test few students make mistakes in solving problems. Based on the research conducted, it can be concluded that LKPD assisted by live worksheets with a problem-based learning approach is effective in improving the mathematical problem solving ability of grade VIII students, especially on the Pythagorean theorem material.

2023-08-01T06:25:49+00:00

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.

The Effect of Problem Based Learning Model on Junior High School Students' Problem Solving Ability

2023-08-02T03:43:02+00:00

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.
