English for Science and Technology: A Study of Cohesive Devices in Computer Science Texts (Published)
The study examined the grammatical cohesive devices in Computer Science texts through a comprehensive genre analysis. The texts were from eight sub registers of Computer Science. The data was collected through the corpus culled from Computer Science texts. The Systematic Functional Linguistics was used as a model of analysis for the grammatical cohesive devices found in the texts. It was discovered that the texts contained grammatical cohesive in the forms of conjunctions and reference expressions. The study also revealed that absence of ellipsis and substitution in the texts. It was equally discovered that the cohesive devices enabled the Computer Science authors to hang stretches of language together and they signaled relations between sentences. The study further highlighted the functions of the cohesive devices in giving coherence to academic writing. Therefore, the grammatical cohesive devices, is an integral part of any form of writing which connected the ideas logically.
Language is a veritable tool for conveying knowledge and information. In the field of science and technology, it is indispensable in disseminating, concepts and facts. Ideas and novel thoughts cannot be formulated without the use of languages in the sciences. Thus, language is the means of understanding science and technology. In fact, language and science are so inextricably linked that learning science is analogous to studying language. However, some second language learners of English fail to realize the relevance of language in the study of science and technology. Also scientific language expressing technical facts pose a lot of problems to second language learners in the field of computer science because the texts introduce the learners to many unfamiliar words. Therefore, this study examines and interprets some technical words in the field of computer science and shows its peculiar usage in the academic context. Excerpts culled from academic journals and texts in computer science are analyzed to explore some ordinary and technical words with specialized meanings. It is discovered that there is a significant number of technical jargons in computer science texts. A major implication of this study is that the second language learners of computer science need to understand and interpret the technical words for their studies and skills in professional communication.
