ABSTRACT

The aim of the study is to know the increase of the students’ activeness as an effort to improve the students’ mathematics learning outcomes of class VIII A of SMP Muhammadiyah 9 Yogyakarta in semester 1 of 2011/2012 academic year by using Student Teams Achievment Divisions (STAD) method. 

The research type of this study is classroom research whose setting is class VIII A of SMP Muhammadiyah 9 Yogyakarta in semester 1 of 2011/2012 academic year. The object of the research is the mathematics learning process using Student Teams Achievment Divisions (STAD). The research is done in two cycles. The analysis is done using descriptive qualitative which comprises diagnostic test technique, observation sheet, field note, and interview with the teacher and students.
The research result shows that using Student Teams Achievment Divisions (STAD) which consists of class presentation, study group, quis, individual improvement, and group apreciaton is able to make the students be more active in learning so that the learning outcomes of SMP Muhammadiyah 9 Yogyakarta students increased. In cycle 1, the average score of students is  69,21 with the highest score of  80 and the lowest score is 40. There are 27 students completed the KKM complited with the classical precentage of 71,05%.

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.

Ellipsis in Discourse Analysis

The essential characteristic of ellipsis is something that is present in the selection of underlying (systematic) option that omitted in the structure. According to Halliday and Hasan (1976: 143), ellipsis can be regarded as substitution by zero. It is divided into three kinds, namely nominal ellipsis, verbal ellipsis, and clausal ellipsis. 1)         Nominal Ellipsis Nominal ellipsis means the ellipsis within the nominal group or the common noun that may be omitted and the function of head taken on by one of other elements (deictic, numerative, epithet or classifier). The deictic is normally a determiner, the numerative is a numeral or other quantifier, the epithet is an adjective and the classifier is a noun. According to Hassan and Halliday, this is more frequently a deictic or a numeral than epithet or classifier. The most characteristic instances of ellipsis, therefore are those with deictic or numerative as head.
