Abstract

In the current era of globalization, students' critical thinking skills are still low, so teaching materials that support learning are needed. In the learning process, educators have not developed teaching materials that are following technological advances, and existing teaching materials use more routine questions so that students only accept and follow the flow and rules rather than experimenting and finding answers or solutions on their own. Therefore, this study aims to produce an open-ended based mathematics e-module product on a system of two-variable linear equations for class VIII students of junior high school, to determine the feasibility of the product in terms of valid, practical, and effectiveness, to determine the increase in students' critical thinking skills after using e-module. This is development research with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). This research was conducted at a Public Middle School in Purworejo for the 2021/2022 academic year. The data collection technique in this study was carried out through questionnaires and tests. The instruments used in this study were validation sheets, questionnaires, and tests. Data analysis techniques use validity, practicality, and effectiveness tests. The results of this study are open-ended-based mathematics e-modules to improve students' critical thinking skills. The product test results showed that the e-module validity score obtained a percentage of 80% from material experts and 82.5% from media experts. The results of the practicality test of the e-module obtained a percentage of 78% from the limited test and a percentage of 74% from the wide test. The results of the effectiveness of open-ended-based mathematics e-module products, namely the N-Gain test, obtained 0.6 in the medium category. The data shows that the e-module developed in this study is categorized as feasible. Students' critical thinking skills after using open-ended-based mathematics e-modules have increased.

Abstract

This study aims to determine the application of the peer tutor method to the mathematics learning process of 5 deaf students in class X SMALB Negeri Slawi. The method used is the descriptive method. The data collection is done by testing, observation, and documentation. Data analysis was carried out by data reduction, presentation, and conclusion, which is the model of Miles and Huberman. Based on the results of data analysis, it can be concluded that peer tutors provide convenience for deaf students with below-average abilities in working on math problems. This is because deaf students get direction and assistance from deaf students who already understand and act as tutors so they can solve math problems. The application of the peer tutor method facilitates the learning process of deaf students. Students communicate with each other to assist, increase learning activity, and solve problems together it can affect the completeness of the learning outcomes of deaf students. In the learning process, peer tutors can be used as an alternatively appropriate and effective learning method, especially for deaf students.

Abstract

This study aims to: determine the effectiveness of the use of instructional media, and determine the practical effect of using instructional media on student learning outcomes. The research method used is descriptive quantitative which aims to describe the practicality of using learning media, the effectiveness of using learning media, and the effect of using learning media on student learning outcomes. The analysis technique used in this study to determine the effect of the practicality of using instructional media on student learning outcomes is simple linear regression analysis. The results showed that the practicality level of learning media was 80%, and the completeness level of students was 76%, so it can be concluded that the learning media developed met practical and effective criteria. The results showed that the assumptions of linear regression were met, namely the data were normally distributed, the data were homogeneous and there was no correlation between the data. So that a simple linear regression test can be carried out partially and the results obtained are tcount = 5.617 which is greater than the value ttable = 2.04841 which means H0 is rejected, so the practicality of using instructional media influences student learning outcomes.

Abstract

Problem-solving ability is one of the higher-order thinking skills (HOTs) that students need in facing the 21st century. The reality on the ground shows that students' problem-solving abilities are still below the KKM. In efforts to overcome this problem, researchers apply Problem Based Learning (PBL) learning to improve students' problem-solving abilities. The research conducted aims to investigate whether the magnitude of the increase in the problem-solving ability of students who learn using the PBL model is higher than that of students who learn using conventional learning. This research is a quantitative study with a non-equivalent pretest-posttest control group design. The population in this study were all students of class VIII SMP Negeri 1 Damar, East Belitung Regency, while the research sample was class VIIIA class VIIIB. The research sample was selected by a simple random sampling technique. The instrument used in this study was a test. The results of the data analysis show that the magnitude of the increase in the mathematical problem-solving ability of students who learn using the PBL model is higher than that of students who learn using conventional learning

Abstract

The background of this research is the learning obstacles that arise on the topic of determining the solution of a system of linear equations (SLE) in applying elementary row operations (ERO). From these findings, it is necessary to formulate a hypothetical learning trajectory (HLT) that can guide the flow of thinking in designing didactic situations in the learning process. HLT expect to anticipate learning obstacles (LO) that arise. This research is a preliminary design of a series of didactical design research. The steps taken in compiling the HLT are 1) reviewing the lesson plan, the methods used to convey the material to determine SST solutions, and the textbooks used; 2) reviewing students' thinking processes conceptually and procedurally regarding theoretically determining SLE solutions; 3) reviewing design plans didactic. HLT is formulated into five types of student responses. It integrates into didactic situations by explaining the relevance of the elimination method in high school with three operations on ERO and then by explaining matrix material before SPL material. From this didactic situation, it can be formulated in teaching material that can accommodate emerging LO.
