Online discussion boards are being used increasingly by tertiary educators as a tool for encouraging greater student interaction and developing learning communities. In particular, educators who have adopted a learner centered, socio-constructivist approach to teaching have sought to facilitate collaborative learning in which students reflect upon and share their experiences and perspectives, and construct knowledge together through developing shared meanings. This paper presents the findings of an electronic survey of the perceptions of 70 distance education EFL and ESL students concerning a compulsory assessment item involving contribution to an online course discussion board. The study revealed that the majority of the students enjoyed the assessment item and agreed that posting to the online course discussion board had allowed them to achieve a range of cognitive and social learning outcomes, as well as to develop some important graduate skills. In particular, ESL students reported the benefits of posting to the discussion board in terms of sharing their experiences with others and reducing the feeling of isolation. Further, when considering social outcomes, ESL students perceive the discussion board provided them with an opportunity to meet and develop a closer relationship with other students in the course and encouraged them to keep up with their studies.
Studies have revealed that online discussions improve students' perceptions of learning, in terms of learning skills and the quality of their learning (Harasim, 1987; Wu & Hiltz, 2004). Indeed, online discussions have been found to result in superior learning and reflection because they place students in "an intellectual environment that encourages active, thoughtful, and equal participation from all comers" (Althaus, 1997). For example, Larkin-Hein (2001) found that online discussions allow students to adopt a more active role in the learning experience and facilitate the acquisition of higher order thinking skills and deep learning (Aviv, 2000; Gibbs, 1992; Murphy & Coleman, 2004; Shapley, 2000). Online discussions allow students to reflect on their responses (Heckman & Annabi, 2003) and encourage "high levels of cognitive engagement and critical thinking" (Aviv, Erlich, Ravid & Geva, 2003; Thomas, 2002; Wu & Hiltz, 2004).
Online discussions provide all students with an equal opportunity to participate, and thus dominant students cannot monopolise the discussion, as can happen in face to face discussions (Ortega, 1997). Moreover, online discussions allow students to interact at their own pace by providing an opportunity to think through their contributions and edit them prior to engaging in the discussion (Biesenbach-Lucas, 2003; Ortega, 1997). In particular, online discussions provide an opportunity for ESL students, who may be reluctant to speak up in a face to face environment, to engage in class discussions (Curtin, 2002; Kahmi-Stein, 2000; Lamy & Goodfellow, 1999; Murphy & Coleman, 2004; Ortega, 1997; Warschauer, 1997). Online discussions allow ESL students to overcome linguistic limitations and express concepts in their own words in English (Biesenbach-Lucas, 2003), as well as, "practise the new language of the knowledge community" in a supportive learning environment (Kahmi-Stein, 2000; Wilson & Stacey, 2004). ESL students often lack the experience of critically engaging with the course content as is required at the tertiary education level (Biesenbach-Lucas, 2003). Compulsory participation in online discussion could be a mechanism for encouraging these students to participate in a "higher level scholarly discourse" (Rossman, 1999). Hence, these many benefits may prompt educators to consider online discussion as a compulsory part of student assessment, and in particular as a strategy for encouraging greater engagement by, and improved learning outcomes for, ESL students.
Based on the review of the literature which indicates that ESL students, in particular, may benefit from participating in online discussions, the following research questions were developed. Compared with their EFL counterparts, do ESL students perceive online discussion to be more beneficial:
Students were required to make at least four postings of 100-150 words across ten weekly topics. The topics were specifically designed for the online discussion task in that they allowed a variety of issues to be addressed, gave students an opportunity to share their own experiences, and allowed a range of perspectives to be presented. The required number of postings was restricted to four, due to limited access to the Internet by some groups of students, as well as university resource implications in terms of monitoring the discussion. However, as the students were formally assessed on their best four posting, many students posted on every available topic. Students were asked to share their experiences and perspectives on a given topic by posting either an original comment, responding constructively to another student's contribution, or synthesising a number of students' responses.
Requiring explicit responses ensures that students are reading and responding to other students contributions (Scarce, 1997). Students were provided with a rubric for assessment which explained that their contributions would be evaluated as being excellent, good, sound, limited or minimal, in terms of: (a) the insightfulness of their comments; (b) their understanding of the underlying theory; and (c) their ability to apply the theory to 'real world' marketing situations. The aim was to gain interaction between students and hence the role of the instructor was primarily to assess contributions, rather than to provide feedback or contribute in the open discussion forum. Students were individually emailed feedback on their contributions by the instructor.
Students were then asked to report on the extent to which they believed the online discussion assessment item which had been set for this course, had allowed them to achieve beneficial learning outcomes and develop important graduate skills. Students were also asked to indicate their attitude toward the online assessment item on a number of dimensions. Their perceptions were measured on five-point scales, with the items being developed from a review of the literature, as well as, an exploratory study that had been undertaken in a previous offering of the course (Birch, 2004). Comparisons of responses between EFL and ESL students were made to test the research questions and thus identify any differences in perceptions across these two groups.
To improve the response rate, the instructors sent reminder emails to students to encourage them to complete the online survey. Students were advised that their feedback would be valuable in terms of assessing the effectiveness of the online discussion assessment item. The teaching team also advised students that a copy of the findings would be uploaded to the course homepage so that the students could see the results of the survey.

Cognitive/social attributes of online discussions that respondents deemed to be particularly beneficial, included gaining feedback on ideas and opinions (94%), learning about other students' views and perspectives (93%), learning from other students' experiences (93%), and interacting with course instructors (93%). No significant differences were found between native speakers of English and ESL students. Other cognitive/social attributes that were also considered to be beneficial, included sharing views and perspectives (90%) and experiences (85%) with others, providing a sense of belonging to a community of learning (84%), and interacting with other students (86%). Apart from ESL students rating the attribute of sharing their experiences with others more highly (t(63) = 2.198, p = 0.032) than their EFL counterparts, no other significant differences were found between EFL and ESL students.
The primarily social attributes of online discussions that were deemed to be beneficial included developing closer relationships with course instructors (90%), reducing feelings of isolation (82%), meeting (67.5%) and developing friendships (68%) with other students. In particular, ESL students agreed more strongly than EFL students that online discussions are beneficial for reducing feelings of isolation (t(63) = 2.464, p = 0.016). This in keeping with findings from previous research which has also revealed that social interaction is cited as a major benefit of discussion board posting by ESL students (Weasenforth et al., 2002). Further, students perceived that online discussions are beneficial in terms of facilitating the development of important graduate attributes, including developing more effective electronic communication skills (85%), and becoming more confident with operating in the electronic environment (79%). Respondents also indicated that online discussions are beneficial in terms of providing a forum for communication at both a time (94%) and a place (88%) that is convenient to them. No significant differences were found across language groups with respect to graduate attributes or convenience items.
The main cognitive learning outcomes that respondents agreed were achieved through the online discussion assessment item included applying the theory to real world examples (86%), thinking more deeply about key concepts (80%), and understanding key concepts (77%). These findings confirm previous research which found that there are significant cognitive benefits to be gained from online discussions including improved learning skills and quality of learning (Harasim, 1987; Larkin-Hein, 2001; Thomas, 2002; Wu & Hiltz, 2004).
In line with the socio-constructivist approach to learning, outcomes which were both social and cognitive in nature included gaining feedback on opinions from instructors (92%) and other students (76%), sharing views and perspectives with others (85%), and sharing experiences with others (80%). These findings support Vygotsky's (1978) social learning concept and the zone of proximal development in which learners are purported to benefit from interactions with and support from more able peers. While many respondents neither agreed nor disagreed with statements concerning the primarily social learning outcomes of the online discussion assessment item, some respondents did agree that it had provided them with an opportunity to meet (42%) and develop closer relationships (29%) with other students. In particular, ESL students agreed more strongly than EFL students that the online discussion assessment item had provided them with an opportunity to meet (t(61) = 2.317, p = 0.024) and develop closer relationships (t(62) = 3.321, p = 0.002) with other students.

To assess the potential of the online discussion assessment item to facilitate the development of graduate attributes, students were asked to respond on the extent to which they agreed that the online discussion assessment item had allowed the development of a range of desired graduate skills (Table 4). Respondents agreed that some important graduate skills had been developed through participation in the online discussion assessment item, including opportunities to improve their ability to present their thoughts and opinions in writing (79%), keeping up to date with their study (71%), becoming more confident in using online discussion boards (69%), and enabling the development of more effective electronic communication skills (69%). In particular, ESL students agreed more strongly than EFL students that the online discussion assessment item had encouraged them to keep up to date with their studies (t(62) = 2.239, p = 0.029).

Only 27% of the respondents agreed that they had experienced some difficulty accessing the course discussion board, while only 20% of respondents indicated that the board took too long to download. ESL students were more likely to agree than EFL students that they experienced difficulty accessing the course discussion board (t(61) = 3.204, p = 0.002), and that the discussion board took too long to download (t(62) = 2.202, p = 0.031). On the negative side, 38% of respondents agreed that the online discussion assessment item was time consuming, and 39% agreed they had problems meeting the deadlines for posting on the weekly discussion topics.
The findings of this study indicate that both ESL and EFL students perceive that valuable benefits are gained from participation in asynchronous online discussions. In particular, respondents perceived significant cognitive benefits and the ability to develop important graduate attribute skills via online discussions. Online discussions support a socio-constructivist approach to learning by yielding a number of outcomes which are both social and cognitive in nature. To a lesser extent the results indicate that online discussions yield some primarily social learning outcomes.
One of the key aims of the assessment was to get students to interact with one another rather than just with the instructor. Two of the four postings required students to make constructive comments on another student's contribution and also to provide a synthesis of a number of students. This raised the exercise beyond purely posting reflections, to allow some degree of student-student interaction. Ideally, with greater instructor resources or a smaller cohort of students, a greater number of contributions requiring increased interaction with other students could be specified.
The focus of this study was to determine whether online discussion could be used as a mechanism for engaging ESL students and whether they perceived greater benefits than their EFL counterparts. In particular, ESL students reported the benefits of posting to the discussion board in terms of sharing their experiences with others and reducing their feelings of isolation. Further, when considering social outcomes, ESL students agreed more strongly than their EFL counterparts that participation on the discussion board provided them with an opportunity to meet and develop a closer relationship with other students in the course, and encouraged them to keep up with their studies.
At the end of semester, the teaching team met to discuss the effectiveness of the online discussion assessment item. The benefits of assessment item were apparent to the teaching team in that students were more engaged with the course and its content over the semester, and their ability to express their thoughts, apply the theory to the real world and use theory to support their arguments improved, as evidenced by most students gaining higher marks for contributions made later in the semester. The instructors were also able to identify students at risk, as well as key problem areas, such as the lack of use of theory to support arguments early in the semester. This gave a chance to provide early feedback to students on their performance and where they needed to improve. Another pleasing outcome was that there were fewer incidents of failure to cite and plagiarism in their major written report. The teaching team noted that the ESL students appeared to have greater confidence at expressing their ideas in their own words, rather than reciting word for word from other sources. However, the teaching team also acknowledged that this assessment item was resource intensive and time consuming.
The findings of this study indicate that some of the barriers to online discussions that have previously been reported in the literature, such as limited access to the Internet and the time it takes to download the discussion board, may now not be as problematic as they have been in the past. However, it should be noted that in this study ESL students experienced greater difficulties than EFL students with respect to access to the course discussion board and download time. Nevertheless, the findings indicate that both ESL and EFL students are receptive to online discussion being set as part of their assessment, and this supports their perception that a range of valuable learning outcomes can be attained through participation in online discussion.
