Abstract

Trigonometry is a part of mathematics in learning that is related to angles. The purpose of this study was to determine the effect of the application of discovery learning methods in students' mathematical proof ability on trigonometry. The research method used in this study is quasi-experimental. The population in this study was the second semester of 2016/2017. The sample was 66 people who were determined by purposive sampling. The instrument used in this study was a mathematically proof ability test. Analysis of the data used is the t-test. The results of this study are (1) based on an average score of mathematical proof ability The student's mathematical proof ability in applying the Discovery Learning Method to trigonometry is not higher than the mathematical proof ability of students who do not use the discovery method (2) there is no significant influence in the application of learning methods Discovery in students' mathematical proofs on trigonometry.

Abstract

We already know that, there are many learning models that are used to improve the ability to understand mathematical concepts. In this study, researchers will use two learning models that have been previously studied. But this study is different from previous studies, this study aims to find a better model in improving the ability to understand students' mathematical concepts through test results by applying the flipped classroom and heuristic vee models. The method used in this study is quasi-experimental (quasi-experimental) and testing using the T and N-Gain test. Based on the results of the data analysis conducted, it can be concluded that increasing the ability to understand mathematical concepts of students who use the flipped classroom learning model is far better than vee heuristics.

Abstract

A graph that has odd harmonious labeling properties is called an odd harmonious graph. The purpose of this research is to obtain a new class graphs construction which is a family of odd harmonious graphs. The research method used consisted of several stages, namely research preparation, research investigation and verifivation of research results. The results of this study, we will give a line amalgamation construction of n double quadrilateral graphs DQ, denoted by *DQ(n) with n>= 1 and graph obtained by connecting between two graphs *DQ(n) with line graph L2, denoted by *(DQ(n),L2,DQ(n)). It has  further been proven that *DQ(n) and *(DQ(n),L2,DQ(n)) have odd harmonious labeling properties, such that all of them are odd harmonious graphs.

Abstract

Objectives The ability to solve problems is to gain knowledge and motivation in the problem solving process of students. The researcher used the IMPROVE and OSBORN learning models to improve problem solving skills. The IMPROVE and OSBORN learning models emphasize the development of optimal mathematical skills and generate new ideas in the process of problem solving. This research is used to see the impact of the IMPROVE learning model and OSBORN learning model which is better in mathematical problem solving abilities. This research uses the Quasy Experimental Design method. Hypothesis testing uses an independent sample test. The conclusion of the study is the mathematical problem solving ability of students who use the IMPROVE learning model is better than the mathematical problem solving abilities of students who use the OSBORN learning model.

Abstract

This study aims to explain the procedural fluency of students in numerical methods courses. Procedural fluency refers to knowledge of procedures, about when and how to use them appropriately, and the skills to carry out procedures flexibly, accurately, and efficiently. The method in this study uses a descriptive method with a qualitative approach and data analysis techniques for the Miles and Huberman models. In this study also performed triangulation of techniques by conducting interviews to strengthen the test result data. From the data analysis, it can be concluded that regarding the smoothness in students' procedural procedures in solving problems related to numerical methods courses, students are able to solve problems with more than one method. However, some students have not been able to streamline steps and make accurate calculations. In addition, mastery in operating a scientific calculator needs to be improved so that students can be more efficient and get more accurate answers.

Abstract

The purpose of this research is to produce the product in the form of audio-visual learning media using Wingeom and Camtasia Studio and to know the learners response to audiovisual learning media using Wingeom and Camtasia Studio. This research uses research and development method. Learning media development procedure is done through several stages: (1) Analysis in the form of curriculum analysis, characteristic analysis of learners and technology analysis. (2) Design  in the form in the media and the preparation of instruments. (3) Development in the form of media creation process until media validation. (4) Implementation in the form of product testing to learners. (5) Evaluation. This research produces a mathematics learning media that has been declared valid and suitable to be used as a medium of mathematics learning by material experts, media experts, and linguists. From the results of validation by experts, then obtained average percentage of 91% with very good criteria. In the test results the average learner responded well with a percentage of 86%. So it can be concluded that the resulting audiovisual media is considered feasible to be used as a medium of learning mathematics.

Abstract

The objective of the study was to analyze the students comprehension ability concept by using Graded Response Models (GRM). This research is a type of qualitative research with descriptive approach. The subjects of the study were students of class VIII of 6 people by purposive sampling. Technique of collecting data is done by written test (essay) and interview. Data analysis technique is using Graded Response Models (GRM) test, which is then combined with data reduction, data presentation, and conclusion. The results showed that students who have high ability category of 18.19%, 60.6% moderate students, and low-ability students 21.21%. This can be seen from the scores obtained from the students ability to comprehend the concept of mathematical concepts, and obtained the graph of parameter estimation results by using Graded Response Models can be increased from the lowest ability of learners that is θ (-4) to the highest ability of learners ie θ (4) for each item item category.
