While there are many distance education studies of student satisfaction or perceptions of CMC, studies on residential student perceptions of CMC are rare. A paper survey was administered to 105 residential graduate and undergraduate students at a midwestern U.S. university. Results indicated that the majority of students preferred face-to-face discussion over CMC for most tasks; however, CMC was preferred overall for simple learning tasks. Content analyses of student responses to open-ended questions revealed that some students perceived face-to-face discussion to be faster, easier, and more convenient, while others perceived that CMC saves time and is more convenient. A discriminant analysis revealed several important factors that predicted those who preferred CMC for discussion. Students further commented that they would learn better from CMC if their instructors were more involved with and enthusiastic about CMC. Speed and convenience appear to be more important to students than whether discussion is face-to-face or CMC.
Blended instruction is becoming more commonplace in higher education. Students not only attend classes, in which they meet face-to-face with each other and their instructors, they also communicate electronically outside of class meetings using course management tools such as WebCT, BlackBoard, Angel, and the like. There has been a considerable amount of research on human interaction and communication in online distance learning. However, there is a paucity of research on computer-mediated communication (CMC) in face-to-face courses. While there are many distance education studies of student satisfaction or perceptions of CMC, studies on residential student perceptions of CMC are rare.
Past Research on CMC and the Fit between Media and Tasks
Computer-Mediated Communication
Media Richness Theory (Daft & Lengel, 1986) presents the idea that the degree of richness of a communication medium is dependent on the capacity of the medium to process ambiguous communication, and suggests that richer media are more effective for equivocal tasks, and leaner media are better for unequivocal tasks. According to the theory, face-to-face communication is considered to be the richest, while other media are thought to be leaner since they have fewer contextual cues and slower feedback compared to face-to-face (Daft & Lengel, 1986). With the advent of the Internet, CMC has been one of the most widely-used communication modes, both synchronous and asynchronous. In educational settings, asynchronous communication remains dominant.
The Fit between Media and Tasks
Many researchers have investigated the "fit" between communication media and task characteristics. While the fit between media and tasks has been studied mostly in business settings in order to improve work performance, it lacks empirical support in educational contexts.
Research Questions The research questions guiding this study are as follows:
Based on previous studies discussed above and Media Richness Theory, we hypothesized that students would prefer face-to-face discussion for equivocal tasks, complex or difficult tasks, and convergent or decision-making tasks, and that students would prefer CMC for unequivocal tasks, simple tasks, and divergent or idea generating tasks.
Participants Residential students were selected in late November 2003 from those studying at the main campus library in a large midwestern university in the United States. Only those who said they had experience with computer-mediated discussion in face-to-face courses participated. This was a convenience sample, since students participated voluntarily. Undergraduate students comprised 53.4% (56 out of 105) of the sample, and 58.1% (61 out of 105) were male. The academic majors of the participants were diverse; they included education, business, mathematics, information science, music, law, psychology, and computer science. Demographic information on the sample is presented in Tables 1.1. to 1.3.
Tables 1.1-1.3. Student demographic information (%, N=105)
Based on known demographics for this campus, the sample we obtained somewhat underrepresented females and younger students. Instrument We developed a semi-structured questionnaire that included four demographic questions, 15 Likert scale questions, five multiple-choice questions, eight dichotomous questions (six of which include open-ended questions), and one open-ended question. Students were asked about their: 1) perceptions of themselves as learners, 2) attitudes toward technology and CMC, 3) experiences with CMC, 4) media preference for different learning tasks, and 5) opinions and beliefs about CMC in face-to-face courses. The students took approximately 15 to 20 minutes to complete the questionnaire. Data Collection and Analysis The researcher and an assistant distributed the questionnaires to students who were willing to participate in the study. A total of 106 completed questionnaires were collected; one was discarded because it indicated that the student had no previous experience with CMC. We used descriptive statistics to analyze quantitative data generated by the dichotomous, multiple choice, and Likert-scale questions. We conducted a content analysis of qualitative student comments in the open-ended questions. For the content analysis of the qualitative data from the six open-ended questions (included in the dichotomous questions which asked the reason for preferring face-to-face discussion or CMC), we copied student responses into a word processor, sorted and grouped them, and labeled the major themes and categories that emerged. For the open-ended question (about perceptions of what is needed for learning best from computer-mediated discussion in a face-to-face course), we wrote individual comments on index cards, sorted and grouped the cards, and identified major categories that emerged.
General Perceptions
Results from the Likert-scale items are presented in Table 2. Most of the students (79%) appeared to be comfortable with computer technology (agreed or strongly agreed with question 6), and 78% had convenient access to the Internet at home and 88.5% at school. About three-fourths of the students believed that they were self-directed learners (73.3%). Nevertheless, only 55.2% of the students stated that they were comfortable with participating in computer-mediated discussion, and about 20% reported that they were uncomfortable with CMC.

Table 3. Student preferences for F2F (Face-to-Face) vs. computer-mediated communication (CMC) (%, N=105))
While 55.2% of the students strongly agreed or agreed that they were comfortable with participating in computer-mediated discussion (Q11), when compared to face-to-face discussion only 34.3% appeared to be more comfortable in CMC than face-to-face discussion (Q20, Table 3), and only 35.2% indicate that they are more active in CMC than face-to-face discussion (Q21, Table 3). The Fit between Communication Media and Tasks For an ambiguous learning task (Q25), 74.3% of the students preferred face-to-face discussion to computer-mediated discussion. Students commented that they preferred face-to-face discussion for ambiguous tasks mainly because it is easier to clarify things through immediate questions and answers. They also pointed out that it is "faster" because they do not have to type all questions and opinions, which might be a considerable amount in the case of ambiguous tasks. Typical comments included:
Table 4. Student perception of the fit between tasks and media (%, N=105)
For a clearly-defined or unequivocal learning task (Q24), 58.1% preferred face-to-face discussion to computer-mediated discussion. More than half of the students appeared to believe that face-to-face discussion (richer media) is "faster," "easier," and "more convenient" for clearly defined learning tasks (or problems/projects). It seems that efficiency and convenience of communication is perceived as more important for unequivocal tasks, while directness and immediacy of communication is valued for equivocal tasks. On the other hand, the 38.1% of students who preferred computer-mediated discussion for an unequivocal learning task suggested different reasons. They stated that they can "save time and energy" because they "do not need to meet" and can work with a flexible schedule. We noted that some students perceived face-to-face discussion as more efficient and convenient while others thought CMC was more efficient and convenient.
For simple learning content (Q27), 59% preferred computer-mediated discussion to face-to-face discussion. The students who preferred computer-mediated discussion for simple learning content appeared to believe that it is "faster" and "saves time" when the content is so simple that they do not need to interact among themselves directly to understand it. They also commented that they preferred CMC for simple learning content because they do not need to coordinate schedules to meet face-to-face and can work wherever convenient. The 40% of the students who preferred face-to-face discussion for simple content, on the other hand, contended that it is faster and saves time because they do not have to type.
For idea generating tasks such as brainstorming (Q22), 73.3% of the students preferred face-to-face discussion to computer-mediated discussion. Students appeared to prefer face-to-face discussion for idea generating tasks mainly because they "can get immediate feedback." Receiving instant feedback on an idea seems very important in idea generating tasks. They also stated that face-to-face discussion is "faster" and "easier" for brainstorming. It was also noted that they can generate more ideas through collaboration and that even incomplete ideas that people present can be useful in building new ideas, whereas these are not available in CMC.
CMC Factors Perceived as Satisfactory or Frustrating
Student responses indicated that CMC is preferred mainly because it saves time and energy that might be spent in face-to-face meetings and because it provides more time to reflect and develop ideas. Students also commented that CMC allows a flexible work schedule, out-of-class cooperation, outside research, and seeing diverse ideas in writing. In addition, some people noted that CMC enables people who are shy in face-to-face discussion or are not fluent in English to engage in discussion more actively.
Needs and Expectations Based on the students' responses to the open-ended question that asked what might help them learn best from computer-mediated discussion, the role of instructors appeared to be most critical in improving and supporting CMC in face-to-face courses. Students reported that if their instructors a) have an enthusiastic attitude toward CMC, b) select appropriate topics, c) provide guidance and structure for discussion, d) regularly participate in the discussion, e) provide immediate feedback, and f) give appropriate credit towards their course grade for participating in CMC, it would help them learn better from CMC. Students' own willingness and motivation to discuss and learn, classmates' commitment and active participation, and high quality of postings were also mentioned as factors facilitating CMC. Some students suggested that they should engage in CMC during class time if it is useful, rather than doing this as extra work outside of class. Others mentioned that they would be willing to have more experience with CMC even though their instructors did not encourage it. Students also indicated a need for visual aids, not just text, and better technology with increased speed. Further Data Exploration with Factor Analyses
To see how responses to the Likert-scale and discrete choice (face-to-face vs. CMC) items were clustered, we conducted factor analyses (image method with varimax rotation). The image method of factor extraction "distributes among factors the variance of an observed variable that is reflected by the other variables … and provides a mathematically unique solution" (Tabachnick & Fidell, 2001, p. 612). Unique and error variance are excluded, since it is the image scores (predicted via multiple regression from other variables in the set) that are used in the covariance matrix from which factors are extracted. The net effect of this is to help prevent spurious results that can be affected by a few extreme cases (e.g., outliers) when sample sizes are not large.
Discriminant Analysis: What Predicts More Comfort With and Activity in CMC?
The subject pool was divided into two groups depending on how students responded to questions 20 and 21. If a subject reported that she or he was both more comfortable with CMC and more active in CMC, then she or he was placed into Group 1 (CMC clearly preferred, n = 29); if face-to-face was clearly preferred, she or he was placed into Group 0 (n = 60). It should be noted that responses to items 20 and 21 were highly correlated (r = 0.634, p<.0005); there were only 15 subjects out of 104 who were more comfortable with CMC but were less active with CMC, or vice versa, i.e., more comfortable with one but more active with the other. These 15 subjects were not included in the discriminant analysis, since these group memberships were small (8 and 7 subjects, respectively).
This discriminant function was highly significant (Wilks' Lambda = 0.599, chi-square = 39.68, df = 5, p<0.0005). This function indicates that students are more likely to be in the group that is more comfortable and active with CMC (Group 1) when they prefer CMC for divergent tasks (that are ambiguous or involve brainstorming—Scale 3), when they are more comfortable/experienced with computer and CMC technologies and are self-directed learners (Scale 1), when they are more likely to agree that they are shy when speaking in front of the class, when their instructor sets rules for CMC participation, and when they prefer CMC for simple tasks. The group that is more comfortable and active in face-to-face discussions (Group 0) prefers face-to-face for divergent tasks, is less comfortable/experienced with computer and CMC technologies and less self-directed, is less shy in speaking in front of class, less active in CMC when instructors have set rules for participation, and prefers face-to-face for simple tasks.
Face-to-face Discussion vs. CMC
Descriptive statistics from this study indicated that residential students overall generally preferred face-to-face discussion to CMC, even though they reported that they were generally comfortable with computer technology, had experience with CMC, and had convenient access to the Internet. Furthermore, students reported that face-to-face communication is faster, easier, and more convenient than CMC (which allows for working at convenient places with flexible schedules). These findings suggest that potential advantages of CMC are not being well utilized in the educational context at this campus.
Efficiency and Convenience Matter More to Students Student responses to open-ended questions revealed that some students perceived that face-to-face discussion is faster, easier, and more convenient, while others perceived that CMC saves time and is more convenient. This implies that students value speed, ease of participation, and convenience in learning activities. Apparently these factors are more important to these students than whether discussion is face-to-face or CMC. Media and Task Fit
According to Media Richness Theory (Daft & Lengel, 1986) and other similar studies (Archee, 1993; DeSanctis & Monge, 1999; Straus & McGrath, 1994), face-to-face discussion is more effective for equivocal, convergent, and complex tasks, and CMC for unequivocal, divergent, and simple tasks. We expected that students would prefer face-to-face discussion for equivocal, decision making, and complex tasks, and that they would prefer CMC for unequivocal, idea generating, and simple tasks. However, the results from our study indicated that students primarily preferred face-to-face discussion to CMC for almost all kinds of tasks, except for simple tasks. Based on the analysis of student responses, we found that students prefer face-to-face communication for tasks for which students need immediate clarification, explanation, and examples. In addition, face-to-face communication appears to be preferable when students need to generate new ideas. Apparently, direct communication stimulates new ideas and helps develop partial ideas by allowing for listening to others think aloud and for spontaneous collaborative thinking.
Conclusion
Our findings indicate that, in general, students hold different values for different tasks. For example, students emphasized speed, ease, and convenience for unequivocal tasks, and directness and immediacy of communication for equivocal tasks. Our findings also suggest a profile for students who prefer CMC over face-to-face discussion; these students constituted about one-third of our sample.
Limitations
This study was based on self-reported perceptions by students, rather than direct observation of their behavior in face-to-face or computer-mediated communication settings. What students say they prefer may not correlate with what preferences might be inferred by observing their actual choices. Moreover, what students prefer does not imply learning effectiveness or efficiency. For example, Raskin (2000) points out that computer interfaces that users prefer are not necessarily those that they are best at using in terms of reduction of errors and speed in task completion. While Raskin's observation is in another field of study, it nonetheless illustrates the issue.
Future Research
Further studies might consider the investigation of student perceptions of synchronous CMC, since the use of synchronous media such as MSN or AOL Messenger (instant messaging) appears to be increasing outside of formal learning settings. It would be interesting to see how students feel about synchronous CMC and using this genre of tools for more formal learning activities. Another option would be to explore student feelings about the use of cell phones and teleconferencing with cell phones. Many students these days walk around campus talking on their cell phones.
