Abstract

The purpose of this research is to analyze the effectiveness of Geogebra learning media in solving math problems among students. The method used in this study is the literature review method with a qualitative approach, which involves a literature review of library sources such as books, articles, journals. Data collection techniques were carried out by conducting literature studies and distributing questionnaires and test questions given to 10 students from class 4C in the 4th semester of Mathematics Education at Indraprasta University PGRI, who were considered to represent the entire research subject. The data analysis technique uses descriptive analytic by collecting data then compiling, analyzing and drawing conclusions. The results of this study indicate that Geogebra is less effective in solving mathematical problems due to lack of knowledge about Geogebra and low interest in using Geogebra.

Abstract

Indonesia is a country that has potential water resources due to high rainfall but is very vulnerable to water crises. This fact shows the great urgency of the need for clean water. One effective solution to deal with this is through the use of rainwater. Harvesting rainwater is an effective step because Indonesia itself has high rainfall so that during the rainy season the product from PT Wujudkan, namely Gama Rain Filter, will collect water and in the dry season it will be used for daily needs. The purpose of this study is to find out about the implementation of the gamma rain filter in increasing access to clean water in rural communities. The research method used is a qualitative approach to gain a deep understanding of the effect of the Gama Rain Filter installation in increasing access to clean water in rural communities. The findings of this study are that with this superior technology, Gama Rain Filter helps people save water resources for drinking purposes during the rainy season. Therefore, existing funds can be used to obtain food sources that contain lots of protein

Abstract

This research aims to analyze mathematics learning, especially in number material, as well as classify students' mathematical problem solving abilities. , interviews and documentation. 12 students have no value, 5 students have moderate values and 3 students have very high scores, the questions given are 5 all description questions. In making mathematical problem solving questions we use indicators namely: 1.) Understanding new mathematical knowledge through problem solving, 2.) Designing mathematical models, 3.) implementing and adapting appropriate strategies to solve problems, 4.) completing models, 5.) monitor and reflect on the process of solving mathematical problems. Of the 5 questions, they are then assessed with an assessment rubik according to the points specified in the question grid used. The results of the assessment were categorized into 3 categories, namely high, medium category, and low category in class IV SD 1 Burikan.

Abstract

This study aims to determine the feasibility of SETS (Science, Environment, Technology, And Society) based modules on colloidal system, determine student learning outcomes after using SETS-based modules in learning and student responses to the modules. This study uses a 4-D development model consisting of define, design, development, and dissemination. This research was conducted at SMA Negeri 11 Medan which was carried out for 7 months. The feasibility of module was seen through a feasibility questionnaire for media and material experts based on the BSNP standard with a Likert scale of 1 to 5. Validation data obtained from media and material experts on SETS-based modules obtained an average percentage of 83.58% with the category valid/worthy. Student learning outcomes were obtained through the calculation of N-Gain test, which was equal to 0.74 in the high category and the average posttest score of students was 84.67. Student responses to the SETS-based module obtained an average percentage of 91.24% with a very high questionnaire interpretation. Based on the results obtained by the researcher, it can be concluded that this SETS-based module is appropriate for use in colloidal learning with a high student learning success rate and student responses that fall into very good criteria.

Abstract

Mathematics is one of the subjects taught at all levels from basic education to higher education, which has a significant role in preparing students to have the ability to think logically, analytically, systematically, critically and creatively, as well as have the ability to work together. One of the activities in learning mathematics at school is through problem solving. Problem solving aims to see students' understanding of a material. Mathematical problem solving ability is a very important part of learning mathematics. However, in reality, the problem-solving ability of junior high school students' mathematics is still very low. From these problems, then one of the lessons that can improve the ability to solve mathematical problems is Problem Solving learning. One of the factors that influence differences in problem solving ability is learning style. Learning styles have a close relationship and influence on the learning process in order to achieve learning goals. With students knowing their learning style, learning Problem Solving can be done easily. The subjects of this study were students of class VIII A MTs Plus Sunan Drajat Kedungsantren Bojonegoro. The purpose of this study was to determine the effectiveness of Problem Solving learning on mathematics learning outcomes when viewed from students' learning styles. The type of research used is quantitative research with the One Group Pretest-Posttest Design. The results showed that testing the data on mathematics learning outcomes with the Paired Sample T-Test stated that the t_count value was -9.726. The t_count value is negative, because the pretest average value is lower than the posttest average value. In this case, the t_count value can be positive so that it becomes 9.726. Meanwhile, the value of t_table with α = 0.05 and degrees of freedom (dk=n-1) with 24 students is 1.714. Then it can be seen that t_count > t_table, then H0 is rejected and Ha is accepted, meaning that there is a significant difference. So it can be concluded that the application of the Problem Solving learning model is quite effectively carried out in the teaching and learning process for class VIII A students of MTs Plus Sunan Drajat Kedungsantren on the material of geometric shapes on the flat sides of cubes and blocks.

Abstract

The research method used in this research is descriptive qualitative research with the aim of the research being to describe the mathematical communication profiles of blind students. This research was conducted at SLB Negeri Rasau Jaya which is located at Education Street No. 2, Desa Rasau Jaya Satu, Rasau Jaya District, Kubu Raya Regency, West Kalimantan Province, using the K13 curriculum. This study will describe the mathematical communication of SLBN Rasau Jaya students in the Cartesian coordinate material seen from aspects (1) The ability of students to give answers using everyday language in explaining ideas, situations and mathematical relations, orally or in writing with real objects, pictures, graphics and algebra. (Aspects of Written text); (2) Students' ability to connect real objects, pictures, and diagrams into mathematical ideas. (Drawing Aspects); (3) Students' ability to express everyday events in language or mathematical symbols. (Aspects of Mathematical Expression). In this study, the subjects of the study were all students of class VIII SLB Negei Rasau Jaya, which consisted of three students with low vision criteria. The data collection tools used in the research were observation sheets, interviews, and written tests. The mathematical communication skills of blind students have good abilities in the aspect of drawing. While the writing aspect was not fulfilled properly and the mathematical expression aspect did not meet the indicators at all.
