Effort of Improving Mathematics Learning Outcomes in the Implementation of Cooperative Learning Model with Student Teams-Achievement Division Type In Class V Semester Gasal Students of SD Negeri Ngebel, Bantul Academic Year 2011/2012


2011. Effort of Improving Mathematics Learning Outcomes in the Implementation of Cooperative Learning Model with Student Teams-Achievement Division Type In Class V Semester Gasal Students of SD Negeri Ngebel, Bantul Academic Year 2011/2012. SI Thesis. Yogyakarta: Ahmad Dahlan University.


ABSTRACT
This research is aimed to improve mathematics learning outcome and to know student respond toward application of cooperative learning model, Student Teams-Achievement Divission type in sub topic of calculating powers and simple root.
This research is a classroom action research. The subjects of the research are class V students of SD Negeri Ngebel, Bantul Academic Year 2011/2012. In plan, the research will be done in III cycles. Because objective of the research has been achieved in cycle II, the research is only up to cycle II. The first and the second cycle consist of 3 meetings. In implementation, researcher is as an instructor and teacher is as an observer. Research instruments consist of observation sheets, interview guidelines, and diagnostic tests tasks.
Result of the research shows that the cooperative learning model, Student Teams-Achievement Divission type can improve mathematics learning outcome of class V students in subject sub calculating simple powers and simple root. It can bee seen from result of observation sheet in 4 meetings which show percentage of student activities in a row are 25%, 50%, 75% , and 83,33% so that can bee said that class V students of SD Negeri Ngebel become more active. Furthermore, result of interviews with teacher and students show positive respond toward the implementation of the cooperative learning model, Student Teams-Achievement Divission type in mathematics learning process. Finally, the results of the diagnostic test in every cycle show enhancement in percentage of classical completeness that is 71, 43% in cycle I and 88, 57% in cycle II.

Substitution: A Grammatical Cohesion

Grammatical Cohesion According to Halliday and Hasan (1976: 4), cohesion occurs when the interpretation of some elements in the discourse is dependent on that of another. It concludes that the one element presupposes the other. The element cannot be effectively decoded except by recourse to it. Moreover, the basic concept of it is a semantic one. It refers to relations of meaning that exists within the text. So, when this happens, a relation of cohesion is set up, and the two elements, the presupposing and the presupposed, are thereby integrated into a text. Halliday and Hasan (1976: 39) classify grammatical cohesion into reference, substitution, ellipsis and conjunction. Substitution Substitution is a relation between linguistic items, such as words or phrases or in the other word, it is a relation on the lexico-grammatical level, the level of grammar and vocabulary, or linguistic form. It is also usually as relation in the wording rather than in the meaning. The criterion is the gram...

Lexical Cohesion in Discourse Analysis

Lexical Cohesion Lexical cohesion comes about through the selection of items that are related in some way to those that have gone before (Halliday, 1985: 310). Types of lexical cohesion are repetition, synonymy and collocation. Furthermore, Halliday and Hasan (1976: 288) divide types of lexical cohesion into reiteration (repetition, synonymy or near-synonym, superordinate and general word) and collocation.
