and discourse analysis; cohesion, coherence and cohesive devices; concept of ESP and ESP
discourse. Moreover, the author would like to describe and analyze grammatical and lexical
cohesive devices in the course book of English for Chemistry for second year students in Faculty
of Chemistry at Hanoi University of Education. The author wishes that the findings of the study
will be applied to the teaching and learning of English for Chemistry.The study consists of three
main parts of which the first part presents the rationales, scope, methodology. The following part
with two main chapters. Chapter one gives the theoretical background of the studies with
theories related to discourse and discourse analysis, cohesion and coherence, ESP. Chapter two
provides an analysis of grammatical and lexical cohesive devices in some written discourses
taken from the textbook of EC used for second year students in Faculty of Chemistry at HNUE
In the final part, recapitulation, implications, limitations of the study and suggestions for further
research are presented.

PART A: INTRODUCTION

1. RATIONALE
Cohesion plays an important role in the comprehension of a written discourse. This
is due to the fact that comprehension is a process that occurs within the reader and is at
least partially dependent on cohesion and coherence. Cohesion is used to show how
sentences which are structurally independent of one another may be linked together.
Cohesion exists within a text and is not the same as coherence, which is something the
reader establishes in the process of reading. The importance of cohesion in text is major
since it provides semantic continuity and permits coherence and comprehensibility. The
more explicit cohesive relationships are, the easier a text is to understand. The coherence
of a text can be created through lexical and grammatical cohesive links and other cohesive
factors. When a reader is able to see how these cohesive factors contribute to the linking of
sentences and ideas in a text, he not only can understand the text but can produce the text
more easily as well.
However, recognizing the relations within the text to obtain coherence is not easy
for learners of English, especially non-English major students. Most of them find it
difficult to understand and produce a text. This is because of the insufficient awareness of
both teachers and learners in teaching and learning English, i.e. learning English is learning
vocabulary and grammar. Moreover, students often learn words in isolation, not in
combinations. Meanwhile, in order to understand a reading text, the readers need to pay
attention to not only vocabulary and grammar but also other factors that create links
between the ideas in the text, i.e cohesive devices.

5. DESIGN OF THE STUDY
The study includes three main parts: Introduction, Development, and Conclusion.
Introduction presents the rationale, the scope, the methodology and the design of the
study.
Development consists of two chapters:

3
- Chapter 1: gives the theoretical background of the study with the theories related to
three main sections: discourse and discourse analysis, cohesion and
coherence, ESP.
- Chapter 2: provides an analysis of grammatical and lexical cohesive devices in some
written discourses taken from the textbook of EC used for second year
students in Faculty of Chemistry at HNUE.
Conclusion provides a recapitulation of the study, implications to teachers and students in
improving the teaching and learning of EC, limitations of the study and suggestions for
further research.
