Abstract. The study investigates the effects of synchronous online discussions on oral and written skills 
development for EFL university students in Vietnam after one semester of instruction, using a pretest-
posttest quasi-experimental approach. One 15-student class of B1-level English participated in oral role 
plays, whereas another 15-student class engaged in synchronous online discussions after comparable 
preparation. The results show no statistically significant differences in oral and written proficiency 
between the two treatment groups at the end of the semester. However, students in both groups achieved 
great progress in speaking and writing skills, especially speaking skill after one semester. The fact that the 
group which used written chat during the treatment had better scores in the oral test at the end of the 
semester strengthens the belief that online discussions support the development of the same processes that 
underlie oral speech. Synchronous online discussions are thus shown to be a valuable addition to the 
foreign language classroom in terms of second language acquisition and learners’ language development.

1. Introduction 
During the last decades, research on computer-mediated communication (CMC) has 
shown an outstanding development in foreign language teaching and learning methodology 
using technology.Countless benefits have been proved through numerous world-wide research 
studies. 
Computer-mediated communication has two modes: asynchronous computer-mediated 
communication (ASCMC) and synchronous computer-mediated communication (SCMC). 
Generally, asynchronous computer-mediated communication takes place in time and place 
independence. Typically, the instructor and students discuss, give and get information or 
deliver materials through the course web pages, posting of forum messages, and listserv or

email messages. In contrast, synchronous computer-mediated communication represents real-
time interactions. Usually, this means that the instructor and students meet in a text-chat room 
simultaneously at a particular location in cyberspace or from any location that has Internet 
access and interact through typed statements or questions [10]. In this study, SCMC is used as a 
synchronous online discussion ortextchat or written chat interchangeably. 
Previous research studies show that there is a link between oral communication and 
online synchronous discussions. Online synchronous discussions not only enhancewritten 
proficiency but also indirectly improve oral proficiency since writing in a computer-mediated 
environment resembles spoken language in terms of its interactional features [1, 4]. 
Withthe increasing use of technology in today's language classrooms in Vietnam, the 
current research is needed to evaluate its effects on EFL learning of Vietnamese students. The 
objective of the present study is to determine the different levels in the oral and written 
proficiency of EFL students between the role-play group and the synchronous online-discussion 
group after one semester of instruction. 
2. Literature review 
Computer-mediated communicationand language development 
The contributionof computer-mediated communication to language development has 
constantly been proved since the early period in CMC’s history. Various meta-linguistic aspects 
of language development have been explored, including negotiation of meaning, sociolinguistic 
environment, and intercultural competence. Furthermore, numerous studies on the 
interactionist approach as well as a sociocultural viewpoint to second language acquisitionhave 
been conducted on the negotiation of meaning and CMC [5]. In addition, Kitade’s findings 
show that CMC is a profitable environment for sociolinguistic development [9]. The author 
concludes that interactional features of CMC facilitate encouraging conditions for developing 
positive attitudes towards language learning: no turn-taking competition, text-based 
interaction, and a lack of nonverbal cues. 
What is more, increasing in linguistic competence, both quality and quantity, among 
learners has also been stated by Kern [7]. He reveals that CMC-supported learners create more 
language production than their friends in the face-to-face group. Kern findsthat SCMC 
discussions produce between two and four times more turns, more sentences, and more words 
than the oral discussions. The research also shows that learners’ language production is at a 
greater level of sophistication regarding grammatical accuracy and complexity. 
Finally, in terms of language skills, both written and spoken skills are enhanced through 
various modes of CMC in language learning projects. In fact, there is a common tendency to

18 
associate CMC with the development of specific language skills [11]. The hypothesis that SCMC 
may improve speaking proficiency has been tested by Payne and Whitney, who find that 
participants in a text-chat room have a significantly higher oral proficiency than those just 
spending time in traditional oral classes [13]. 
In short, it is obvious that CMC has been used widely in developing most language areas 
and skills, except for listening skills ... en tests. 
Furthermore, a pre-treatment questionnaire was distributed to the two selected classes 
after the participants had been briefed on the purpose of the study and had an opportunity to 
ask questions about what would be involved.

First, to achieve the aim of the research, descriptive statistics (means and standard 
deviations) were computed. Table 4 shows the means and standard deviations for the pre- and 
post-treatment scores in the oral test and the written test according to treatment (role play, text 
chat).

Both groups receive higher means in the post-treatment tests at the end of the semester, 
which indicates increased oral and written proficiency (Table 4). The standard deviations for 
both groups seem quite large, suggesting rather variable levels of proficiency within the 
different groups at the beginning and at the end of the semester. 
Usually, educators expect instruction to have a positive effect on students' learning, 
resulting in higher means in a post-test. This is the case here, too, with the two groups showing 
gains in measurements of oral and written proficiency levels. Furthermore, educators also 
expect that instruction would result in students' similar performance in thepost-test, indicated 
by a smaller standard deviation, which is also the case here. From the researcher’s viewpoint, 
several factors might have contributed to the current picture. First, the treatment using 
synchronous online discussions might have had a more positive effect on students' performance 
in an oral test than the treatment using face-to-face discussions (the difference between oral pre-
tests and post-tests in the text-chat group is 1.60 and that in the role-play group is 1.10); a 
possible reason for this effect might be that the language which was practiced duringtext-chat 
sessions is more similar to oral speech than to written language after all.Another possible 
reason is that the students monitor the use of grammar and vocabulary better in text-chat 
messages. The third reason might be that the text-chat discussion generates plenty of ideas. 
Second, the text-chat group hasbetter scores in oral tests than in written tests in spite of writing 
text-chat messages as treatment during the semester (1.60 in the oral test compared with 1.03 in 
the writing test). The oral test of the text-chat group achieves the best scores among the four 
tests both in oral and written tests at the beginning and at the end of the semester. This confirms 
the assumption that synchronous online discussions might have a positive effect on speaking 
skills. Third, oral role-playing as a treatment does not seem to have any leveling effect on 
students' performance in either oral test or written test. 
In general, language learners in their English course of one semester might develop so 
differently from one another that no matter what kind of treatment they receive, they show very 
different profiles concerning their proficiency levels at the end of that semester.

As can be seen in Table 5, the mean scores of oral and written tests between pre- and 
post-treatment in the text-chat group are higher than those in the role-play group. Thisshows 
that students achieve great progress in speaking and writing skills, especially speaking skill 
after one semester of using synchronous online discussion although there is no statistically 
significant difference between the two treatment groups with p = 0.078 and 0.660 (>0.05). The 
fact that the chat group achieves a better gain in oral proficiency at the end of the semester 
indicates that having students engage in synchronous online discussions is not counter-
productive to the development of their oral language skills. This finding further supports the 
hypothesis of the study that learners might improve their oral skills using synchronous online 
discussion. 
Since the two different treatment groups have different mean gain scores, especially 
regarding their oral proficiency level, the researcher decided to run paired samples (matched) t-
tests to compare the groups' performance before and after the treatment. Table 6 indicates 
thatthe two groups independent of treatment have a significant gain in oral and written 
proficiency between the beginning and the end of the semester. Significance levels are reached 
by the oral role-play and the text-chat groups for both oral and written proficiency gain.

Although the specific treatment does not seem to have different effects on the 
development of students' oral and written proficiency, the instruction that they receive during 
the semester results in a significant increase in their proficiency levels. It is important to note 
that the data also show that having students engage in synchronous online discussions is not 
counter-productive to the development of their oral language skills, a result which further 
supports Payne and Whitney's hypothesis that SCMC develops the same cognitive mechanisms 
that underlie oral speech. 
Pedagogical implications

Given the very positive reactions of the participating students to the integration of web-
based search activities in their English lessons, followed by oral role plays or online discussions, 
the increased use of technology in the foreign language classroom is certainly recommended 
from a motivational point of view. Students today not only wantto use technology, but they also 
know that they have to be good computer and Internet users in order to be competitive in the 
job market. Web-based search activities with ensuing role plays offer numerous benefits. They 
provide the learners with an experience of authentic language use through the up-to-date 
information and cultural authenticity of the visited webpages. 
Moreover, it also allows learners to make meaning connections instead of translating the 
words, thus contributing to vocabulary acquisition. Using role plays based on the gathered 
information gives learners appropriate communicative tasks to engage in and provides them 
with opportunities to practice their language skills in a useful context. Open-ended and 
meaningful activities are considered conducive to the enhancement of oral and written 
proficiency because they provide opportunities for creative use of the target language in a range 
of contexts and a variety of functions. 
Transposing the role plays to a written mode by using synchronous online discussions 
offers many additional benefits. First of all, it slows down the overall conversation rate among 
the learners in a group, giving everyone time to think about and edit a message before they 
send it out, thus affording slower or more reserved students the opportunity to contribute just 
as much as the faster or more outgoing students. Second, all learners are engaged in a 
conversation at the same moment and practice their language skills, without having to wait 
until they are called upon by the teacher, disappearing into the background, or fighting for the 
floor; all of which are typical for the more traditional classroom. Third, transcripts of online 
discussions provide excellent examples of learner language use, indicating students' status, and 
giving the teacher the opportunity to revise the curriculum to integrate remedial activities when 
necessary on the basis of the observed mistakes. Fourth, according to the comparable results 
achieved by the text-chat group in their oral and written performances, it seems that using 
written online discussions aids in the practice and development of both written and oral skills 
and that they are accepted by the students as a viable alternative to oral classroom practice. 
5. Conclusion 
As mentioned before, the goal of this study is to provide more insight into the 
development of language learners, especially with regards to the effects of synchronous online 
discussions. It also aims at reflecting current pedagogical ideas in its study design in a variety of 
forms. Engaging students in meaningful activities that promote an open-ended exchange of 
information has been considered facilitative for students' learning [6].

Synchronous online discussions were treated in this study because they are motivating; 
they address the needs of today's learners to be computer-literate; they also accommodate 
different learning styles. The most important reason, however, is that online discussions have 
been called a "hybrid" between oral and written language.The pace and the informal style of 
oral speech are expressed in writing, which slows the conversation down and makes it 
permanent. Text-chat sessions can be arranged outside of class, becoming time- and location-
independent meeting points for learners to practice and improve both their written and their 
oral skills. However, in order to shed further light on these issues, more studies investigating 
learners’languagedevelopment within a communicative framework are needed.
