An investigation into the effects of group work in teaching speaking skills to ESP students at danang university of medical technology and pharmacy (DUMTP)

etnam. She 
divided them into three sub-sections: needs for ESP in professional activities, needs for communication in 
ESP, and needs for ESP at workplace. The article helped orientate purposes of future use of ESP. However, 
the findings were too general to be realized in reality (Do Thi Xuan Dung, 2011). Similarly, Lam Quang 
Dong (2011) mentioned general concept on ESP and focused on the analysis of professional area’s, work 
market’s and learners’ needs as well as learners’ English proficiency. Generally, the reasons for ineffective 
ESP teaching and learning in Vietnam were that the educators and teachers could not yet determine the true 
needs of ESP learners and factors relating to the quality of ESP teaching and learning (Lam Quang Dong, 
2011). However, his conclusion on all these matters was quite unclear and subjective. It is advisory to have 
a deeper and larger investigation in order to provide valid and reliable results on a scientific basis. 
In short, the findings in the above research articles by Cepon (2016), Do Thi Xuan Dung (2011) 
and Lam Quang Dong (2011) opened up a great variety of research approaches. Based on these initial 
research foundations, the current study aimed to make a quasi-experiment on the effects of group work 
activities in teaching ESP speaking skills to general nurse students of DUMTP. 
3. Methods and materials 
3.1. Research methodology 
This is a quasi-experimental study involving quantitative and referential statistics to elicit responses 
from students regarding group work. In order to investigate the research questions for this study, a quasi-
experimental design was chosen. Quasi-experimental designs are defined as being similar to experimental 
designs in that the purpose of the method is to determine a cause and effect relationship and that a direct 
manipulation of conditions is involved. However, in contrast to the experimental design, a random 
assignment of the subjects to different treatment groups is not possible. The present study used "intact” 
classes, which are six classes of Nursing ESP module. They were already organized as classes based on the 
class establishment decision by the Dean, which means that a random assignment to the different treatments 
was not feasible. 
3.2. Participants 
 The participant pool is comprised of all third-year students enrolled in the Nursing ESP course in the 
fifth semester of the entire Nursing course at DUMTP. They had finished the first two General English 
modules during the first and second semester at DUMTP before they took this ESP course in the fifth 
semester of their entire course. The ESP course consisted of 75 class hours and the textbook used during 
the course was Nursing 1 by Tony Grice (2007), published by Oxford University Press. 
ơ3.3. Sampling method 
The study applied total population sampling, which involved the entire population of third-year 
general nurse students of the academic year 2013-2016 at Danang University of Medical Technology and 
Pharmacy with 282 students. Nursing ESP students comprised the largest group, outnumbering other groups 
learning ESP at DUMTP in the first semester of the academic year 2013-2016. 
3.4. Research materials 
Questionnaire: The questionnaire consisted of 24 items, divided into two sections. The first section 
with 14 items was for the participants’ bio data, their perspectives on ESP learning purposes, how often 
they spoke English, their attitudes toward speaking in English in class, whether they took any extra English 
course after class, their own evaluation on their English proficiency as well as the major difficulties in their 
English learning. The second section with 10 items was related to their own evaluation of the difficulties 
and challenges of learning ESP. 
Pre- and post-treatment oral tests: The participants were given oral tests at the beginning and at the 
end of the semester. 
3.5. Procedures 
 Pre-oral test of English proficiency was administered before the treatment of ESP. 
Initially, research subjects consisted of 282 students, divided into six classes whose name lists were 
decided at the beginning of the course by the Dean of DUMTP. However, 17 students who did not 
voluntarily participate in the research team or take the pre-oral test were deleted from the subject list. 
Therefore, the actual number of subjects voluntarily participating in my research was only 265. One class 
was randomly selected for traditional lecturing, two classes for traditional lecturing and group work 
discussion combined, and three classes for group work discussion. Three teachers (including the researcher) 
were involved in this study, in which each teacher was in charge in one selected mode. Before the treatment, 
the researcher explained the syllabus, lesson design and what three different methods are as well as the 
purpose of the research study so that all the three treated their selected classes equally. 
- Post- treatment oral test was given at the end of the semester. 
- Questionnaires were filled out on the completion of the ESP module. 
3.6. Data analysis and process 
- Research data were entried and managed, using Epidata 3.1. 
- SPSS 16.0 was used to process and analyze the data. 
4. Findings and discussion 
4.1. Background information 
The findings showed that 94% of the participants are female. Almost half of the research participants 
came from rural areas while very few of them were from urban areas. Most participants were found to start 
learning English in Grade 6, making up over seventy percent. Some others who come from urban areas 
started in Grade 3. This fits the curriculum promulgated by the Ministry of Education and Training. 
 One noteworthy thing is that few research participants, only one and a half percent, often 
communicate in English. Some revealed that they never spoke English despite the fact that they had 
experienced eight years of learning English up to the time of this study. A half of the participants said they 
sometimes spoke English. This result was similar to the findings from the research by Pham Dang Tram 
Anh and Luu Quy Khuong (2015). 
Additionally, the study found out various reasons for the participants’ low English proficiency. The 
reasons were as follows: the participants’ not being involved in classroom activities; their being passive 
and unready to acquire EFL (English as a foreign language); and their being reluctant to answer their 
teacher’s questions. It was their EFL learning style that hamper their progress in EFL learning because 
language learning requires frequent practice and taking risks in vocabulary and structure manipulation. 
Very few participants reported that they were usually actively involved in the English lesson by voluntarily 
answering their teachers’ questions. As seen in table 2, only 10,2% self-rated their English proficiency 
fairly good, no single student self-rated very good.

4.2. The main difficulties in learning ESP speaking 
Figure 1. How difficult to learn ESP speaking skills 
Figure 1 showed that ESP speaking learning is difficult. The study explored the certain factors that 
made it difficult for the participants to speak English, which were rated by the participants themselves. 
Those factors causing most problems were correct pronuncation, complete sentence reading, nursing 
professional text reading, understanding others, being confident in speaking, grammar and structure. 
Students put the following factors at a level of moderate difficulty: vocabulary, nursing professional 
knowledge and motivation for ESP speaking. The result demonstrated that the research participants faced 
a wide range of obstacles in learning ESP speaking skills. 
4.3. Effects of group work in teaching EFL speaking skills 
Figure 2. Success to failure ratio of speaking test 
As can be seen in Figure 2, the results showed the success to failure ratio of the speaking test at the 
beginning of the ESP module (entry level) is 57.7% to 42.3% and that after treatment with group work,

traditional and combination (output level) is 87,5% to 12,5%. There is a statistically significant difference 
in success and failure ratio between pre- and post-treatment with p<0.05. This figure illustrated that the 
treatment had some impact on ESP speaking improvement. However, whether the improvement was 
because of the manipulation of various teaching techniques or because of the students’ ESP learning during 
one semester, the following findings helped answer this question. In addition to the curriculum and teaching 
materials, the way how teachers develop different teaching and learning activities and techniques will bring 
different results (Ur, 2000). 
Figure 3. Measurement on effect of the three experimental teaching techniques 
Figure 3 measured the effect of each teaching technique in order to enhance ESP speaking skills. 
The difference between success ratio of the speaking test and different teaching methods had no 
statistical significance with p>0,05. In other words, the participants’ ESP speaking skills improved 
after one semester treatment no matter what teaching methods were used. 
5. Conclusion 
With reference to the first reasearch objective: To determine the passing ratio/score (entry level) on 
English speaking skills of general nurse students who are learning ESP at DUMTP, the success to failure 
ratio of pre-treatment EFL speaking test (entry level) is 57,7% to 42,3% whereas that of post-treatment 
(output level) is 87,5% to 12,5%. Relating to the research objective 2: To explore the effects of group work 
activities in teaching English speaking skills for general nurse students who are learning ESP at DUMTP, 
the manipulation of various teaching techniques was to some extent effective, there was an increase in the 
percentage of passing level of speaking test: from 57,7% before treatment up to 87,5% after treatment. In 
connection with the effect of each technique, there was not much difference among the three techniques. 
Figure 3 showed that the failure ratio of the group with groupwork method was higher than that of traditional 
and combination teaching methods. This can be explained that no matter what teaching method was used, 
if the teachers did not employ it appropriately in their class, they might end in failure. 
 In sum, the combination between two or more teaching techniques in teaching ESP speaking would 
be more effective than rigidly applying only one certain technique throughout the course. More importantly, 
teachers need to be trained how to manipulate the teaching methods successfully in their class. It is the 
teacher as a key factor that decides what and how should be conducted to gain positive achievements. 
6. Implications 
English language is very important for this development phase of our nation as the National Foreign 
Language Project 2020 specified (Vietnamese Government, 2008a). Therefore, it is imperative that every

individual student make every effort to become competent in the English language. To achieve this 
objective, English teaching methodology must be upgraded and used effectively. The teachers who teach 
ESP to nurse students, in particular, need pedagogical skills as well as English proficiency in order to be 
successful in their teaching. In addition, material developers need to take into account employers’ and ESP 
learners’ needs to design appropriate ESP textbooks. Last but not least, whatever technique the teachers 
would manipulate, they should devise detailed plans and be well-prepared in order to take all advantages 
of it.
