Simbolisasi dalam Metode Numerik sebagai Representasi Konsep dan Prosedur Fauzi Mulyatna; Wahyu Kusumaningtyas
Numerical: Jurnal Matematika dan Pendidikan Matematika Vol. 1 No. 2 (2017)
Publisher : Institut Agama Islam Ma'arif NU (IAIMNU) Metro Lampung

The purpose of this research is to analyze the ability of interpret symbols in numerical methods. The extent of the interpretation at the level of procedure and calculation only, or its already at the level of understanding of the concepts represented by symbols with good and right way. This type of research is qualitative research. The data that obtained are analyzed in descriptive. The election of the subject based on purposive sampling technique, i.e. taking the subject with considerations/criteria 6 semester students who was taking the course numerical methods, critical and active in discussions. The subject is only drawn by 1 student, subsequently coded MN1.The material is focused in determining the approximate root of equation with the method of false position. The methods used to collect data in this research is the observation, tests and interviews. So, that the triangular used in this research is the triangular techniques. Conclusion based on the results of the research showed the new symbols to interpret NM1 limited calculation procedure only. NM1 considers, with the same symbol but different forms of counting operation, was a mistake. NM1 gives the wrong result of conclusion renders the procedure is only seen from the similarity to the symbol, not the views of the concept behind the use of the symbol.

The purpose of this article is to determine whether there are elements of mathematics contained in the intestine motif based on the concept of geometry. Subjects in this study consisted of 4 people obtained by purposive sampling technique. From the results of data analysis conducted by using descriptive analysis and discussion as follows 1) Intestinal embroidery motif contains the meaning of mathematics and culture or often called ethnomathematics. On the meaning of culture there is a link between the embroidery intestines with a culture that has been there before as the existence of cultural linkage between Hindu belief Buddhism and there are similarities of motifs and decorative patterns contained in the motif embroidery intestine with ornamental variety in Indonesia; 2) The relationship between the intestines with mathematical motifs there are elements of mathematics such as geometry elements in the form of geometry of dimension one and dimension two, and the geometry of transformation. The concept of one dimensional geometry is a line, while the two dimensions are elliptical and rhombic. The concept of transformation geometry includes reflection or reflection, in which case this reflection is most prevalent in a motif contained in the intestinal embroidery motif, dilation or diminution and enlargement, rotation or rotation and translation is a shift.

Pengembangan Desain Didaktis Bahan Ajar Materi Pemfaktoran Bentuk Aljabar pada Pembelajaran Matematika SMP Rizki Wahyu Yunian Putra; Nurwani Nurwani; Fredi Ganda Putra; Nugraha Wisnu Putra

The ability to understand a concept in the learning of mathematics is something that is required by each learner. But in fact show that in the learning process, teaching materials used have not trained learners in doing a discovery and learners less active in the learning process. This study aims to produce teaching materials in the form of a didactic design module teaching materials Algebra on Mathematics Subjects for Class VIII Semester 1 Subject material Algebra in SMP Negeri 1 Pakuan Ratu. The teaching materials module with didactic design is a module in the form of a learner's guide which contains information, materials about Algebra, examples of problems as well as exercise questions, in accordance with the problems that natural learners on learning materials, this instructional material is made to petrify participants educated in solving problems on Algebra material. Based on the results of research, Didactic instructional materials developed by researchers deserve to be used according to the validation results of material experts, linguists, education practitioners, media experts, and help learners to learn more independently and comfortable in the learning process as well as learners are very interested in teaching materials (modules) of this didactic design.

Proses Berpikir Mahasiswa Dalam Menyelesaikan Soal Kombinatorial Berdasarkan Kecerdasan Logis Matematis Lilia Sinta Wahyuniar; Santi Widyawati

The thinking process of each student varies in solving mathematical problems. The process of thinking in this study are grouped into three conceptual thought process, semikonseptual, and computational. The objectives of this research are to investigate the thinking process of IT student with the high logical-mathematical intelligence in solving kombinatorial problems, the thinking process of IT student with the moderate logical-mathematical intelligence in solving kombinatorial problems, the thinking process of IT student with the low logical-mathematical intelligence in solving kombinatorial problems. This research is descriptive qualitative whichdescribes the process of thinking of students in solving mathematicalproblems on material kombinatorial. The data collection method in this study using tests and interviews. Subjects of this study were six students from 1D grade IT of Universitas Nusantara PGRI Kediri and represented two student with the high logical-mathematical intelligence, two student with the moderate logical-mathematical intelligence and two student with the low logical-mathematical intelligence. Data analysistechnique used Miles and Huberman, data reduction, display, andconclusion drawing / verification. Based on the analysis we concluded thatstudents with high logical-mathematical intelligence haveconceptualthought process, the thinking process of student with the moderate logical-mathematical intelligence no identified, students with low logical-mathematical intelligence have computationalthought process.

Efektivitas Pembelajaran Berbasis Schoology choirudin choirudin

Schoology e-learning as one of Learning Management System (LMS). By using schoology aims to show the effectiveness of schoology e-learning through students’ outcome in material quadratic equation. This is achieved when the students’ learning outcomes were taught by schoology e-learning can reach KKM, process skills and students’ activities are better than conventional methods, process skills and students’ activities get a positive effect on students' learning outcomes. This study hypothesis analysis used t-test and linear regression. The results were obtained on experimental class KKM, with the average value of these classes also proved that the experimental class average is better than the control class where control class. Skills process positively to the learning outcomes of mathematics at 24,2%. Having an active students learn mathematics positive about the outcome of 19,8%. Process skills and students active learn mathematics positively to 25,7%.

Lembar Kerja Peserta Didik Materi Aritmatika Sosial dengan Model Pengembangan Thiagarajan Isnaini Nur Azizah

This research aims to produce comic-based LKPD comic products on the subject of social arithmetic and how to develop comic-based LKPD to be effective. This research uses research method of development of Thiagarajan-4D model, which consists of 4 stages, namely definition, design, development and dissemination. This study begins from a preliminary study in the form of needs analysis consisting of learner analysis, material analysis and task analysis. Preliminary study results indicate the need for the development of comic-based LKPD on the subject of social arithmetic. The development of worksheet based comic begins with arranging worksheet design and all components based on guidance of worksheet preparation in the form of draft 1. The draft 1 has been compiled and then validated by expert to produce draft 2. The validation result indicates that worksheet has fulfilled the content and design feasibility standard. The draft 1 is then refined to produce draft 2 and tested to several learners called a limited trial. The results of a limited trial show that worksheet is included in either category.
