Abstract

In this study using classroom action research.  The goal is to find out information on the application of the discovery learning  model to online learning of set materials to improve the learning outcomes of junior high school students. With the implementation of research on class VII-E students at one state junior high school in Cimahi City, totaling 37 people. This class action research is carried out in 2 cycles, where each cycle has 2 meetings. The research instrument uses observations, study test results, and journals conducted online. Analyze the data in the form of average and percentage results with descriptive statistics. The average score of 71.64 with a percentage of 56.75% is the learning outcome of students in the first cycle and the average score of 80.74 with a percentage of 86.48% is the learning outcome of students in cycle II. The activities of teachers and students in each cycle in online learning are quite good and effective but there is something that needs to be improved in student activity during the online learning process. It is concluded that there is an increase in student learning outcomes in online learning, so the discovery learning  model can be applied to class VII students of the set material.

Abstract

This research is motivated by the low ability of students to understand basic concepts and students' interest in learning mathematics. The purpose of this study was to determine the improvement of student learning outcomes through the use of Problem-Based Learning in class X mathematics subjects. The research method used was qualitative and quantitative data analysis, with the research subjects of all 34 students of class X. Based on the processing and results of data analysis, the application of the Problem-Based Learning model in mathematics learning has increased after the actions of cycle I, II, and cycle III were held. Student learning outcomes in the first cycle have an average grade of 73.5%, student learning outcomes in the second cycle have slightly increased, namely the average grade of 81.4% and classical absorption of 73.5%, then proceed to the cycle III and experienced an even better improvement, with an average grade of 83.5% and classical absorption of 88.2%. The conclusion of this research is that learning mathematics using Problem-Based Learning can improve the learning outcomes of class X students at SMA Karya Pembangunan Cicalengka.

Abstract

This aims study to analyze the mathematical comprehension ability of student in calculus course. Sample of research is student of informatics engineering at Universitas Mitra Karya. The type of research used is descriptive qualitative research. The data collection techniques used in this study included conducting preparatory activities, testing mathematical comprehension in the form of essays tested for validity, power, and difficulty index, collecting data, and distributing data. to analyze and draw conclusions. The instrument is a math comprehension test in the form of 5 text questions. The results of some math comprehension tests still show below average results. From this it can be concluded that students' understanding is still relatively low. As for the student’s difficulties in solved the problem of mathematical comprehension ability for indicators of identifying and making examples and not examples, changing one form of representation to another, and identifying the properties of a concept.

Abstract

The purpose of this research is to explain the improvement of mathematics learning outcomes for grade VII students at SMP Negeri 2 Cimahi with the “Realistic Mathematical Education approach”. This research method is classroom action research. The subject of this research is 15 students from VII grades. The device used in this research is an essay test with 4 questions. The test is used to reveal students' mathematics learning outcomes. As a data analysis of student mathematics learning outcomes in the first cycle are students who have completed (33%) and students have not completed (67%), while in cycle II students who have completed become (73%) and have not completed (27%) the average value the class increased in the first cycle = 58 while the class average value in the second cycle = 79 which significantly increased, thus according to the results of the data analysis obtained, it was concluded that through the Realistic Mathematical Education Learning approach, students were able to improve mathematics learning outcomes in class X software engineering.

Abstract

This study aims to examine the application of a scientific approach in improving the learning outcomes on the material of Relations and Functions. The research subjects were students of class VIII-D of SMP Pataruman for the academic year 2021/2022 as many as 20 people. This research is a classroom action research conducted in two cycles consisting of four meetings. The stages of this research are: Planning, Action, Observation, and Reflection. This stage is applied repeatedly to achieve the target so that student learning outcomes experience an increase in the mastery of learning scenarios. The results showed that the application of the scientific approach was able to improve learning outcomes in each cycle. It can be shown that the average score in the first cycle was only 57.3% and increased in the second cycle to 81.85%. Student learning outcomes increased by 24.55% from the first cycle to the second cycle. So it can be concluded that the scientific approach is believed to be very effective and has a positive effect on learning that is able to improve student learning outcomes in the material Relations and Functions in class VIII-D SMP Pataruman.

Abstract

Mathematical analogy reasoning ability can help students solve two math problems that have the same concept but with different problem forms. Therefore, this article aims to reveal and describe the mathematical analogy reasoning abilities of high school students in solving curved side geometrical problems. This research is a qualitative research with descriptive method. The subjects used were 3 students out of 30 students in class X-3 SMA Negeri 2 Karawang which were obtained from the results of categorizing mathematical analogy reasoning abilities. The data collection technique used was a written test. This ability is measured based on the stages of analogical reasoning, namely encoding, inferring, mapping and applying. Then data analysis is carried out by reducing data, presenting data, and making conclusions. The results of this article show that of the three subjects who can fulfill the stages of encoding, inferring, mapping and applying, only KA students. NZ students are only able to achieve two stages of analogical reasoning, namely encoding and mapping. Meanwhile, VA students have not been able to fulfill all the stages of mathematical analogy reasoning given. Therefore, efforts are needed to improve students' mathematical analogy reasoning abilities.
