Abstract

In industrial revolution 4.0, education must follow and utilize information and communication technology. Android is an operating system on mobile devices, and Indonesia's most popular and widely used mobile device operating system. The Open-Ended approach is an approach in mathematics learning that provides opportunities for students to explore open problems with various strategies for solving problems. One problem that often arises in learning in schools is the study of the anchovies of each textbook varies, and the material contained in the book does not match the characteristics of the students. To realize this, the world of education needs to implement the use of e-Modules. Seeing this problem, the development of an android-based e-Module with an open-ended approach is required. Research and development with the ADDIE model is this type of research. The subjects of this study were as many as 15 middle school students in grade 8 for limited tests and 30 students for a broader test. The research aimed to produce Android-based electronic teaching materials with an open-ended approach to square and triangular materials. The resulting product is an e-Module in the form of an android package kit (APK). The result of the study concluded that the development of teaching materials with an android-based open-ended approach went well with the practicality test results obtained by 83%, which means that the teaching materials are efficient to use and got 86.6% in the effectiveness test, which means that the teaching materials developed are suitable for use.

Abstract

This study aims to produce teaching materials based on the GeoGebra-assisted Problem Based Learning approach that are valid, effective and practical to improve mathematical mathematical communication skills in linear programming material. The subjects in this study werw 30 students for a limited trial, 60 students for a broad trial, and 60 students for product testing including 30 experimental class and 30 control class. The instruments used in this study were interview sheets, student observation sheets on learning, response questionnaires to learning, validation questionnaires, five questions about mathematical communication ability tests, and non-test questionnaires for students' self-confidence. The results of this study indicate that the process of developing teaching materials is carried out well and the product is feasible to use, mathematical communication skills and self-confidence of students who receive learning using the GeoGebra-assisted Problem Based Learning method are better than students who receive learning using the usual approach, difficulties during learning do not indicate a high level of difficulty, in terms of mathematical communication problems students have difficulty in perfoming algebraic operations and more than half of students respond positively to learning.

Abstract

With the deepening of the reform and development of the new curriculum education in the 21st century, the mathematics core accomplishment has been paid more and more attention by middle school teachers, among which, the logical reasoning ability is one of the important contents of the mathematics core accomplishment in middle school. The research purpose of this paper is to solve the problem of middle school students mathematical logical reasoning ability is not strong, starting from the mathematical problem itself, to explore how to cultivate students' logical reasoning thinking ability and teaching methods. This paper adopts the literature analysis method to summarize and analyze the relevant literature, uses the case analysis method to deeply analyze the relevant classic examples, and uses the statistical analysis method to analyze the students' logical reasoning literacy. Through the analysis of cases and students, this study believes that having the ability of mathematical logic reasoning can help students to solve mathematical problems, and similarly, it also promotes the development of students' mathematical logic reasoning ability in the process of solving problems. When cultivating students logical reasoning ability in problem-solving problems, we can start from the following aspects, 1. Pay attention to the study of basic knowledge, 2. Cultivate students' observation ability, 3. Analysis and prove with the help of innovative problems.

Abstract

This study aims to determine the feasibility of LKPD teaching materials with the probing prompting learning model to facilitate the mathematical problem solving abilities of junior high school students on the flat-sided building material (cubes and blocks) and to determine student responses to the developed student worksheets (LKPD). This study uses research and development methods with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The results of the research data obtained, and it can be concluded that the student worksheet (LKPD) of the probing prompting model is suitable for use with the results of the material test ( x = 33), mathematics education test ( x = 54), and media expert test ( x = 63). Student responses when viewed based on the results of the overall aspect value of the limited scale test, the value ( x = 45.71) is in the very feasible category. Meanwhile, the students' responses to the wide-scale (field) test based on the overall aspect scored (x  =46.81) with a very decent category.

Abstract

Education is one of the learning processes to improve a person's skills and behavior. Mathematical understanding is the ability to understand concepts, the ability to distinguish concepts, and the ability to calculate complex situations or problems. Adversity quotient is the response of a person or individual when faced with problems or difficulties in his life. The main problem in one of the schools in Sumedang is the students' thinking about mathematics lessons, where this lesson is less preferred than other lessons. The method used by this study is descriptive quantitative. This research was carried out in the even semester of 2021/2022, in one of the regional schools in Sumedang, class VII totaling 15 students. The data generated from this research is in the form of an instrument, which consists of indicators of students’ mathematical understanding and there are 3 questions on indicators of mathematical understanding. The methods of data collection in this study are as follows: 1) test descriptions of questions or instruments to determine students’ understanding abilities, 2) direct interviews with students. Research results from student answers according to students’ understanding abilities in terms of AQ, as follows:  1) The results of student responses in terms of Adversity Quotient as many as 3 Climber type students (high) the average percentage of students’ understanding ability is 80%, 2) The results of students responses in terms od Adversity Quotient as many as 9 Climber students (enough) the average percentage of students’ understanding ability is 5,77%, 3) The results of students responses in terms of the Adversity Quotient as many as 3 students Cumper type (medium)the average percentage of students’ understanding ability is 15,1%.
