Theoretical Framework COHESION IN STUDENTS’ SPEECHES (The Case of the Third Semester English Language Students of UNNES)

Lexical cohesion is, in many ways, the most interesting of all the cohesive categories. The background knowledge of the reader or listener plays a more obvious role in the perception of lexical relationships than in the perception of other types of cohesion. Collocation patterns, for example, will only perceived by someone who knows something about the subject at hand. Nunan 1993: 30 Thus, collocates can be words used in the same context or it can be words that contribute to the same area of meaning Kennedy: 2003. For example, a text dealing with the chemical treatment of food contains lexical chains such as: fruit, skin, citrus, lemon, orange, chemicals, products, laboratory …etc. these words can be said to belong to the same register and contribute to the same topic.

2.3 Theoretical Framework

The framework of the study is based on the analysis of the cohesion with devices used in the organization of discourse. The cohesive devices are functioned to distinguish the relations of the sentences within the discourse to be considered as so called a text. The devices used are the ones introduced by Halliday and Hasan 1976. There are five types of devices in forming the unified texts. The first is reference, the relation between an element of the text and something else by reference to which it is interpreted in the given instance. It includes personal, demonstrative and comparative reference. The next is substitution, the replacement of one item by another. It consists of nominal, verbal and clausal substitution. The third is ellipsis, the substitution by zero. It includes nominal, verbal and clausal. Then, there is conjunction, including additive, adversative, causal and temporal. The last is lexical cohesion consisting reiteration and collocation. personal reference Reference demonstrative reference comparative reference nominal substitution Substitution verbal substitution clausal substitution nominal ellipsis Ellipsis verbal ellipsis Cohesion clausal ellipsis additive conjunction adversative conjunction Conjunction causal conjunction temporal conjunction other conjunctive items Lexical Cohesion reiteration Collocation Figure 2.3 The Classification of Cohesion according to Halliday and Hasan 1976 Figure 2.4 Theoretical Framework Cohesion in Students’ Speech the case of the Third Semester English Language Students of UNNES Reference Substitution Ellipsis Conjunction Substitution Lexical Cohesion Grammatical Cohesion Analyze the cohesion of the speeches produced by the third semester English Language students 43 CHAPTER III METHODS OF INVESTIGATION Chapter three focuses on the methods of investigation. In this chapter I would explain the research design, subject of the study, object of the study, roles of the researcher, unit of analysis, instrument for collecting the data, procedures of collecting the data, and procedures of analyzing the data.
