INTRODUCTION 

Learning vocabulary is fundamental to support the learners to master 

English, because the ability of students to read and comprehend the subject 

material is relatively determined by their vocabulary. When the students have 

good vocabulary, they can understand paragraphs and texts better. Basically 

most learners know how important the words in a language is and they also 

realize that vocabulary learning strategies can be a very helpful device in their 

vocabulary learning journey. On the other side, for teachers, teaching 

vocabulary is very important not only for the students in school level but also in 

university level, one of them is Muhammadiyah University of Metro.

Computer Science is one of the majors available in Muhammadiyah 

University of Metro which aims at preparing the students to face the global 

world. The students of this department are expected to know things related to 

the computer science field especially know how to solve computer problems, 

how to design computer network and to understand computer components. 

Therefore, on graduating from the department, the students can directly work. 

One of the ways to prepare the students to be as expected is by giving them 

English. When the students are qualified, they will be able to apply for a job 

successfully.  

In teaching English to Computer Science department, a lecturer should 

have appropriate media to make the learning more interesting and thus the 

students do not feel bored. In addition, the process of learning should be varied 

too so that the students feel enjoyable and fun during the process. And this is a 

challenge for the lecturer! One of the ways to make interesting and enjoyable 

class is by using media as media can be used to motivate the students in the 

learning process. To use media effectively a lecturer needs creativity because 

creative media will increase the probability of the students to learn more and 

better. In sum, a lecturer should create various teaching media to increase 

interests of the students. 

However, during the learning, the researcher found some problems in the 

students of Computer Science Department, especially when learning English 

for Specific Purposes (ESP). The problems were: students lack the vocabulary, 

the students’ vocabulary mastery is still low, most of the students have 

relatively low learning motivation, and the students were difficult to translate 

the Computer Science terms into English.  Furthermore, the students were 

difficult to learn English (ESP) because the book used only contains the 

exercises and less material explanation. 

Based on the problems identification above, the researcher choose to 

develop an instructional media that can make students have practice and 

improve their vocabulary independently. By doing such a study, it’s hoped that 

it can help students to learn English more easily and successfully.  

 

Theoretical Reviews on Terms Related to the Study  

According to Handayani (2007) vocabulary is knowledge of word and 

meaning. Based on the statement, vocabulary is all the words in a language that 

are familiar and used by someone to comunicate with each other. According to 

Lewis (in Tanto, 2014) there are four categories of vocabulary i.e. Listening, 

Speaking, Reading, Writing vocabulary. So, in English there are four skills that 

should be mastered, and each skill needs vocabulary mastery.  

According to Hornby (2009) development is the process of producing or 

creating something new or more advanced. During the process of development, 

the important things need to pay attention on are innovation and creativity.  

According to Sugiono (2009) Research and development is a research method 

which can be used to produce a certain product, and test the effectiveness of the

product. Based on the explanation, it can be concluded that research and 

development is a research method aims to produce certain products and test the 

validity and effectiveness of the product in its apllication. 

Media is anything used to send messsage(s) from the sender(s) to the 

receiver(s), so it can arouse the learners’ thought, feeling, and interest to gear 

the students’ learn (Sadiman et al, 2002). According to Ruis et al (2009) media 

is very useful in learning English. Based on the explaination, it can be 

concluded that learning media is a means or educational tool that can be used as 

an intermediary in the learning process to enhance the effectiveness of learning 

process. For a learning process, teaching media of a tool used in order to make 

communication and interaction between lecturer and students more effective. 

According to Nasution (2003), module is a complete unit that stands 

alone and consists of a series of learning activities arranged to help students 

achieve a number of objectives formulated specifically and clearly. According 

to Meyer (in Lasmiyati, 2014) module is relatively short self-contained 

independent unit of instructional designed to achieve a limited set of specific 

and well-defined educational objectives. Based on the explanation above it can 

be concluded that the  module is a tool or means of learning in which it can be 

in the form of materials, methods, and evaluations made systematically and 

structured as an effort to achieve the objectives of the expected competence. 

Module is designed specifically and clearly based on the speed of 

understanding of each student, thus encouraging students to learn according to 

their ability.  

Component of module in Dasna et all. (2006) consists of three parts, 

namely: introduction, contents, and end. The introductory section consists of 

cover, introduction, table of contents, guide for readers. The content section 

consists of the division of subject matter, each of which consists of several 

components: subtitles, student worksheets, material descriptions, and questions. 

The final section contains glossary and bibliography. Module development has 

certain components that must be considered by a lecturer because a module has 

an important role for both teachers and students. With the module that fits the 

characteristics of students and learning objectives, the level of students' 

understanding of the lesson will increase. Module is one of the principles of 

applying individual learning. With the module, students are free to implement 

learning according to the speed and opportunity of each. More importantly, 

students are no longer passively listening to the lectures from the leacturer, but 

students are expected to actively respond the learning process by listening, 

reading, evaluating, witnessing demonstrations, and interacting with fellow 

students and lecturer. 

According to Hutchinson and Walters (in Puspitasari, 2013), ESP is an 

approach in the language teaching where content and methods are based on the 

students' reason to learn. ESP is a specific learning.  

English for Computer Science is a teaching approach in order to achieve 

the goals or competence of the students to master English in the field of
