Research Questions Electronic lexicon on nursing (e-lon): a Computer Assisted Vocabulary Learning (CAVL) model to enhance nursing students` lexical retention.

but also discuss students’ attitudes toward the use of CALL in their vocabulary learning Hassan, R.E.H., 2010; Shao, J., 2012 and Dewan, G., 2013. Hassan 2010 sur veyed students’ perceptions on what extent the computer-aided vocabulary learning improves their vocabulary. The result shows positive responses. The majority of students reported that they like using the software in studying vocabulary. The students felt that the software support the learning process especially in terms of introducing word knowledge in different context, instant feedback, multiple word retrieval, and recognition for comprehension. In the study of Shao, multimedia application-based vocabulary acquisition has been used to explore the effectiveness of multimedia application and the interest level of Chinese college students with multimedia software they work with. This study also gives reflections on the shift of teacher’s role from conventional teaching at classroom setting to teaching with multimedia environment. Likewise, the study of Dewan 2013 shows that the CAVL package were helpful for students to learn and retain vocabulary knowledge. Dewan focused more on students’ behaviour in using CAVL package. This study reported that there was no relationship between test- scores and the frequency of word look up features though there were a large number of the students’ look-up clicks on the word features in the CAVL package. The previous studies have generally supported the idea that computer assisted vocabulary learning facilitates second language vocabulary acquisition and has provided with some practical and theoretical insights to understanding the computer assisted vocabulary learning. All of them used experimental research to investigate the effectiveness of CAVL in vocabulary learning and some of them conducted a survey to know students’ attitudesperceptions. The results of those PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI studies are helpful for the researcher to design a CAVL mod el to enhance students’ vocabulary retention. In the next section, the review of theoretical literature on vocabulary learning and memory retention is highly necessary to provide deeper understanding on how a word is acquired and storage in the memory. In addition, the following explanation gives foundation information before designing vocabulary learning mediated computer to improve learner’s lexical retention.

B. Theoretical Review

In this section, some related theories from different literatures are discussed. This part presents the theories of English for specific purposes ESP vocabulary, English for nursing, vocabulary acquisition and retention, vocabulary learning materials, computer-assisted vocabulary learning, an overview of iSpring suite application, and instructional system design models.

1. ESP Vocabulary

Specialised vocabulary in ESP has important role. It shows what kind of ESP the learners are focused on. According to Coxhead in Patridge and Starfield, 2013, there are some reasons why vocabulary need to be specific in ESP course. Firstly, selected words in learning materials which is directly related to learners’ language needs will make their classroom time more valuable. Secondly, when learners understand and try to use this special purposes vocabulary indicates that these learners belong to a particular group. In other words, it will be helpful for ESP learners if they are exposed with useful vocabulary related to their field. The other reason is the size of specialised vocabulary is not fully established. It means that ESP learners probably face so many learning tasks to develop their
