THE RHETORICAL STRUCTURE AND COMMUNICATIVE STRATEGIES OF THESTUDENTS’ REQUESTS IN THE WEB DISCUSSION FORUM

This paper is to describe the rhetorical structure and the communicative strategies that students use in the web discussion forum of Ma Chung University. This web discussion forum allows the participants, especially students, to share their ideas, opinions about the current issues in the campus in the form of written texts. Among 11 students who get involved in discussing two issues, the campus bell and hair coloring, they are most likely to attend to directive based rhetorical structure when they have the same opinions. By contrast, representative based rhetorical structure becomes more obviously apparent when they have diverse opinions among themselves. In order to strengthen the perlocutionary force of the utterance, the students are also most likely to use some communicative strategies such as a colloquial and native language, abbreviation, capitalized letters and emoticon

Violated Maxim in the Amazing Spider-man 2 Movie

This study is concerned with an analysis of Grice's Cooperative Principles whichare constituted in a conversation. This research was conducted by usingqualitative method. The analysis particularly discusses the violation of maxim inthe utterances, which are described in four types. They are the maxim of quantitymaxim of quality, maxim of relation and maxim of manner. The data of this studyare the utterances of the main character in The Amazing Spider-Man 2 movie. Theutterances which contain violated maxim are identified and analyzed. Thefindings show that there are 51 utterances violation of maxim in The AmazingSpider-Man 2 movie. Those are 20 utterances (39.2%) violation of maxim relationand it can be concluded as the dominat type violated, 16 (31.5%) for maxim ofquantity as the second largest number violated and 8 (15.6%) for the maxim ofquality. The last, those are 7 utterances (13.7%) violated maxim of manner. Itshows that the maxim of manner is the lowest number. Based on the analysis,there are the reasons as the main backgrounds which prompt the main characternamed Peter Parker to violate the maxims. The reason are to keep the secret andchange the topic

DEVELOPING THE STUDENTS’ SPEAKING ACHIEVEMENT BY USING PROBLEM BASED INTRODUCTION MODEL AT GRADE X OF SMK ASAHAN KISARAN IN ACADEMIC YEAR OF 2016/2017

The title of this study is the Developing the Students’ Speaking Achievement by Using Problem Based Introduction. The objective of the research was taken from the grade X students of X TKJ 1 SMK Asahan Kisaran. Problem Based Introduction (PBI) is a learning process towards a way of solving its problems more focused on the creativity and skills, such as formulating the problem by forming small groups, give ideas, conduct research, discuss and presentation. PBI learning model (Problem Based Instruction) is one of many innovative learning model. This model presents a state of active student learning and engage students in a problem-solving through the stages of the scientific method. There were only one class consist of 30 students. The result of the first cycle is 52 %  and the result of the second cycle is  87 % After the Problem Based Introduction model was implemented and developed through two cycles, it is concluded that this model can develop the students’ achievement in speaking. In addition the students’ opinions toward the implementation of problem based introduction were positive. The average of first cycle and second cycle shows that the research is succeed.  Keyword : Problem Based Introduction Model, Speaking Achievemen

THE INFLUENCE OF STUDENT TEAM ACHIVEMENET (STAD) TO THE STUDENTS’ LEARNING OUTCOMES IN CIVICS SUBJECT AT CLASS X OF STATE SENIOR HIGH SCHOOL 7 BINJAI

This study aims to determine the effect of STAD cooperative learning model on student learning outcomes in Civics subjects in class X SMA Negeri 7 Binjai. The problem identification in this research is the lack of student’s interest in the subject matter, this is because in general the Civics subject uses lecturing and rote method, lack of facilities for Civics subjects, and low student learning outcomes. The formulation of the problem in this research is whether there is influence of Cooperative STAD learning model on student learning outcomes in Civics subject. The type of research used in this study is experimental research. While the method used is quantitative method. Hypothesis in this research is there is influence of STAD type cooperative learning model to student learning result in civics (PPKn) subject. The population in this study amounted to 36 people and the sample in this study amounted to 20 people who said population samples taken by using simple random sampling technique or taking sample members of the population conducted randomly. The average value of the pretest result of students is 56.75 with a standard deviation of 282.30. And for the average value of posttest result of student equal to 77, 75 with standard deviation 1296, 11. From result of calculation of hypothesis test got r_h = 2, 48 and r_t lies 0,444. So there is influence of Cooperative STAD learning model on student learning outcomes in the eyes of Civics class X SMA 7 Binjai. With r_ (count) (2.48) and r_tabel (0.444). With t_ (count)4.65> 1.73. From r_ (table) it shows that there is influence between two variable

On Multiscale Methods in Petrov-Galerkin formulation

In this work we investigate the advantages of multiscale methods in Petrov-Galerkin (PG) formulation in a general framework. The framework is based on a localized orthogonal decomposition of a high dimensional solution space into a low dimensional multiscale space with good approximation properties and a high dimensional remainder space{, which only contains negligible fine scale information}. The multiscale space can then be used to obtain accurate Galerkin approximations. As a model problem we consider the Poisson equation. We prove that a Petrov-Galerkin formulation does not suffer from a significant loss of accuracy, and still preserve the convergence order of the original multiscale method. We also prove inf-sup stability of a PG Continuous and a Discontinuous Galerkin Finite Element multiscale method. Furthermore, we demonstrate that the Petrov-Galerkin method can decrease the computational complexity significantly, allowing for more efficient solution algorithms. As another application of the framework, we show how the Petrov-Galerkin framework can be used to construct a locally mass conservative solver for two-phase flow simulation that employs the Buckley-Leverett equation. To achieve this, we couple a PG Discontinuous Galerkin Finite Element method with an upwind scheme for a hyperbolic conservation law

Multiscale Finite Element Methods for Nonlinear Problems and their Applications

In this paper we propose a generalization of multiscale finite element methods (Ms-FEM) to nonlinear problems. We study the convergence of the proposed method for nonlinear elliptic equations and propose an oversampling technique. Numerical examples demonstrate that the over-sampling technique greatly reduces the error. The application of MsFEM to porous media flows is considered. Finally, we describe further generalizations of MsFEM to nonlinear time-dependent equations and discuss the convergence of the method for various kinds of heterogeneities
