Publisher: Institut Agama Islam Negeri Raden Intan Lampung

This research is qualitative descriptive research. This research has purpose to describe student error in resolving matter inequality of calculus I. The subject of this research is taken from student of mathematics education Unipdu semester II academic year 2016/2017. Data collection method used in this research is using test method and interview method. Before the researchers conducted the analysis, the researchers examined the validity of data using time triangulation to obtain valid data. Then from the data that has been validly analyzed new then drawn a conclusion. From result of research got result that 1) Subject A do 9 kind of errors, that is: error in determining condition of a root, mistake in doing process calculation, error determines value x on a number line, mistake determines set of settlement, error in determining sign interval at Line of numbers, errors in determining the completion region on the line of numbers, the error in determining the value of the zero maker on the split points, the error in determining the value of the zero-maker on the number line, the error of not continuing the completion process; 2) Subject B performs 8 types of errors, the type of error is the same as subject A, except error in determining the requirements of a root.

Pendidikan matematika selama ini tidak berhasil meningkatkan pemahaman matematika yang baik pada siswa, tetapi berhasil menumbuhkan perasaan takut, persepsi terhadap matematika sebagai ilmu yang sukar dikuasai, tidak bermakna, membosankan, menyebabkan stres pada diri siswa. Kreativitas dalam berfikir sangat mempengaruhi proses belajar. Kemampuan matematika bagi siswa dalam proses belajar selanjutnya maka masalah rendahnya hasil belajar matematika siswa dan sikap siswa terhadap matematika yang cenderung negatif perlu diupayakan pemecahannya. Penelitian ini merupakan penelitian kualitatif deskriptif. Penelitian ini menggunakan metode tes. Validitas data dalam penelitian ini dilakukan dengan meningkatkan ketekunan dan triangulasi waktu. Adapun teknik analisis data dilakukan dengan reduksi data dilakukan dengan cara memilih hasil pengerjaan siswa. Hasil reduksi yang telah dipaparkan, kemudian dipaparkan dalam bentuk analisis. Hasil penelitian menunjukkan bahwa: 1) Mempelajari pola bilangan lebih menarik dan mudah jika menggunakan pendekatan matematika realistik. 2). Pembelajaran matematika realistik memperkenalkan masalah yang bersifat aplikatif dalam kehidupan sehari-hari sehingga pembelajaran akan lebih bermakna. 3) Pembelajaran matematika realistik menekankan pada penanaman konsep pemahaman, kreativitas siswa dan poses nalar dalam matematika.

Culture-based education has a vital role of individuals and communities to achieve progressivity in all aspects of life. Math-based culture called ethnomathematics is an approach that can be used to explain the role of mathematics in a multicultural society. Mathematical concepts used to explore the existence of mathematics in culture, especially traditional societies of Lampung. This study aims to describe the results of exploration Lampung Ethnomathematics with this kind of exploratory research as well as an ethnographic approach. The results showed that without studying the mathematical concept, traditional society of Lampung have applied these concepts in their daily lives using ethnomathematics. Proved the existence of mathematical concepts contained in custom home building, the local unit of Lampung, geometric shapes motif of tapis, as well as traditional games Lampung. Researchers suggest the results of this study to (a) used as alternative ideas mathematics learning outside the classroom, (b) introduced in learning formal mathematics as initial capital to teach the concept of mathematics to students, (c) be used as reference material for preparing a matter of mathematical problem-solving context.

Learning style is one of the factors that allegedly affect the learning achievement (GPA) of Mathematics Education Mathematics Program of Maarif Nahdatul Ulama Institute of Islamic Studies. The purpose of this research is to know "whether there is influence of learning style type (Visual, Auditorial, and kinestetik) to student learning achievement of Mathematics Education Program of Maarif Nahdatul Ulama Islamic Institute of Mathematics”. The type of this research is comparative causal research with 3 × 1 research design. The population in this research is all students of semester IV of Mathematics Education program of Maarif Islamic Institute Nahdatul Ulama Metro academic year 2015/2016. The sample in this study was obtained by using class random technique. The sample in this study consists of 22 students with details of 10 students who have visual learning style, 4 students who have auditorial learning style, and 8 students who have kinesthetic learning style. Instruments used to collect data are questionnaire learning style and transcript of student grades semester IV of Mathematics Education Mathematics course Maarif Nahdatul Ulama Institute of Islamic Studies. Hypothesis testing in this study used a one way variance analysis with unequal cells.The result of this research is the influence of learning style to learning achievement (GPA) of Mathematics Education Mathematics Program of Maarif Nahdatul Ulama Institute of Islamic Studies. Furthermore, after further test using Scheefe 'method, it was found that students with visual learning styles had the same learning achievement with students with auditorial learning style, while both types of learning styles had better learning achievement compared with students with kinesthetic learning style.

Let be a ring, a strictly ordered monoid, and K, L, M are R-modules. Then, we can construct the Generalized Power Series Modules (GPSM) K[[S]], L[[S]], and M[[S]], which are the module over the Generalized Power Series Rings (GPSR) R[[S]]. In this paper, we investigate the property of X[[S]]-sub-exact sequence on GPSM L[[S]] over GPSR R[[S]].
