It is costly for faculty to deal with cheating. Keith-Spiegel et al. (1998) identified several of these costs and argued that they can be grouped into four categories: emotionality, difficult, fear, and denial. I argue that the emotional and fear costs for faculty make it unlikely that the common approaches to dealing with plagiarism will be effective. I provide an example of an old approach which diminishes some of the costs for faculty.
Evidence indicates that cheating on written assignments is common, perhaps more common than cheating on exams. For example, statistics reported by Premeaux (2005) indicate that students estimate that the "percentage of students you think cheat on a typical written assignment" is about 45% while the "percentage of students you think cheat on a typical exam" is about 32%. Hollinger and Lanza-Kaduce (1996) report that about 38% of students admitted that they had plagiarized during a fifteen-week period.
While cheating appears to be common, catching students cheating is less common. Roig (1997) reports that 3% of students "admitted to have been caught plagiarizing." Diekhoff et al. (1996) find that about 2% of students say "that they had ever been caught cheating during their tenure as college students." Diekhoff et al. do not single out plagiarism.
The disparity between the statistics on cheating and getting caught is striking. The statistics indicate that the chance that an individual will be caught in a particular instance of cheating is quite small. Given the common approaches to dealing with plagiarism, the statistics suggest that the costs imposed by faculty on students for plagiarism are quite low.
Keith-Spiegel et al. (1998) identify costs for faculty of dealing with cheating. My purpose in this paper is to examine the implications that these costs have for the effectiveness of the common approaches to dealing with plagiarism. This examination suggests a course of action — an oral exam — that may be appropriate for some faculty in some situations.
Common Approaches
Plagiarize is defined in Webster's Ninth New Collegiate Dictionary (1988) as "to steal and pass off (the ideas or words of another) as one's own." Writing manuals provide additional information. For example, the Little, Brown Handbook (1989) states "When you summarize or paraphrase, you do not use quotation marks because the words are your own. However, you must acknowledge the author of the idea." Even though this seems straightforward, Roig (1997) finds that "students are often unclear as to what constitutes plagiarism and correct forms of paraphrasing." Furthermore, Roig (2001) finds that faculty also have difficulty understanding plagiarism. Accordingly, one approach to dealing with plagiarism is education.
Landrau, Druen, and Arcuri (2002) find that simply educating students about plagiarism leads to a decrease in plagiarism. Barry (2006) finds that practice paraphrasing by students leads to a decrease in plagiarism.
A second approach to dealing with plagiarism involves the method of designing and carrying out the assignment. Well-known techniques include assigning a narrow topic and requiring an outline and multiple drafts. Wilhoit (1994) advises instructors to "require students to submit photocopies of documented materials."
A third approach is to emphasize that plagiarism is wrong and that efforts will be made to detect plagiarism and penalize those who are caught. Brown and Howell (2001) find "that having the students read a carefully worded statement about plagiarism was an effective way to change the perceptions of how seriously plagiarism breaches academic guidelines." McLafferty and Foust (2004) describe various electronic tools that can be used to detect electronic plagiarism. Martin (2005) used electronic means to detect plagiarism, told the students he was doing this, and told them that in prior semesters he had detected plagiarism and reduced grades accordingly. Martin found that this approach resulted in a decrease in plagiarism over a period of five semesters.
Costs
Although the common approaches seem like they should work, the high incidence of plagiarism coupled with the low faculty-imposed costs borne by students indicates that frequently, faculty are not effective at deterring plagiarism and faculty choose not to impose costs on students for plagiarism. Presumably, the costs for faculty of dealing with plagiarism are high relative to the benefits for faculty of achieving a low incidence of plagiarism.
Evidence on the costs for faculty is provided by Keith-Spiegel et al. (1998) in their survey of psychology faculty which investigates "why professors ignore cheating." They find that the stated reasons can be grouped into four categories: emotionality, difficult, fear, and denial. The emotional category primarily reflects the stress of the accusation and the ensuing process. The difficult category primarily involves the time and effort of dealing with the cheating. The fear category captures the fear of reprisals. The denial category reflects the sentiment that action is not necessary.
Keith-Spiegel et al. find that emotional costs are stated most frequently, but time and effort are not far behind. Fear is part of the calculus but is not mentioned as frequently as the first two categories. Denial is not stated frequently.
The evidence produced by Keith-Spiegel et al. suggests that the common approaches for dealing with plagiarism are problematic. Even if faculty were willing to devote the time and effort to use the common approaches, the emotional and fear costs would limit their effectiveness. For example, the penalty approach is unlikely to be effective because faculty will choose not to follow through with it; the emotional and fear costs are too high. This is one explanation for the results of Bunn, Caudill, and Gropper (1992) who expect the severity of the penalty to be negatively related to cheating, but find a positive, non-significant relation. Although bluffing may work for a time, it is unlikely to work after students learn that faculty will not follow through with the penalty.
Similarly, the education and assignment design approaches may decrease plagiarism somewhat, but faculty are still left with the problem of what to do when plagiarism does occur. Again, as students learn that faculty will not follow through with the penalty, the effectiveness of these approaches will be limited.
An Old Tool
An examination of the costs for faculty of dealing with cheating suggests that there may be merit in an old tool — using an oral exam along with a paper. Instead of proving plagiarism and penalizing it, the instructor demonstrates and grades the disparity between what the student represents as his own work and what the student understands.
Oral exams, of course, are not new. Prior to 1850 they were widely used, but in the second half of the nineteenth century they were generally displaced first by written exams, and later by objective exams (Ebel 1972). According to Ebel, "the major limitation of the oral examination is the difficulty of obtaining reliable scores in reasonable amounts of time." Since the paper suffers from this same limitation, substituting one for the other in some way — adding an x minute oral exam and subtracting y pages from the paper — does not appear to increase the cost unreasonably, but yields the benefit of giving instructors a palatable approach to dealing with plagiarism.
In a course where the content is specialized knowledge, the instructor chooses a narrow area in which he is qualified to grade papers. The instructor selects a specialized journal appropriate for the course, each student chooses a different article from the journal, and each student writes a paper on the article. For example, either the Journal of Portfolio Management or the Financial Analysts' Journal works well for a senior-level investments course in finance. These journals have short articles, 3-5 pages, written at a level (i.e., the practitioner level) which allows students to understand at least some of the articles. The instructor must read the articles, but by limiting the choice to one journal, he increases the chance that students choose articles he has already read or would read anyway. Students are advised not to select articles that are too simple or too difficult because their goal is to convince the instructor that they have learned enough to read articles in the journal he has selected. This is achieved by writing a clear paper and providing informed answers to the instructor's questions during the oral exam.
The oral exam takes place in the instructor's office and lasts 15 to 20 minutes. Several days in advance of the oral exam, the student turns in his paper and a copy of the article. Before the oral exam, the instructor writes several questions he might ask; he also writes the answers to these questions. This makes it easier for the instructor to take a few notes quickly during the oral exam and helps keep the discussion flowing smoothly. Because the student and the instructor each have a copy of the article during the exam, the instructor can ask detailed questions about tables, equations, words, and explanations.
I have used oral exams along with papers many times. If I suspect that work is not the student's own, then it is easy to question the student intensively about it during the oral exam. If the oral exam demonstrates that the student's understanding is not commensurate with what he has represented as his own work, then I grade accordingly.
Time and Effort
The oral exam is one more use of the instructor's time. Extra time is needed to read the article, to write questions for the oral exam, to conduct the oral exam, and to write comments afterward. These time costs can be managed to some degree by decreasing the length of the students' papers. I have found that using a short paper (e.g., 3 pages) along with an oral exam still takes a little more time than a long paper (e.g., 10 pages) without the oral component. Because an oral exam and a carefully graded paper are time-consuming activities, this approach is only appropriate when used with a small number of students (e.g., 20 or fewer).
Institutional policies sometimes require written assignments in courses which have a large number of students. In this case, it may not be possible for the instructor to become well informed on the topic(s) on which the students are writing, to carefully grade the papers, and to effectively deal with cheating on written assignments. The oral exam/paper does not overcome flawed policy.
Discussion
To the extent that the stated reasons for ignoring cheating are also the actual reasons for ignoring cheating, an oral exam alleviates some of the costs for faculty. Because the instructor avoids an accusation of plagiarism and the ensuing process, the oral exam/paper appears to eliminate, or at least greatly reduce the emotional and fear costs of dealing with plagiarism. A stressful confrontation is replaced with the routine task of grading the disparity between what the student represents as his own work and what the student understands.
The oral exam/paper calls for a low grade when this disparity is large. The common approaches to dealing with plagiarism are often accompanied by penalties such as an "F" for the course, a mark on the student's record, or suspension from college. In contrast to the difficulty of administering the severe penalties used with the common approaches, the moderate penalty used with the oral exam can be easily administered whenever it is warranted. Carter and Punyanunt-Carter (2007) report that students find severe penalties to be less acceptable than moderate penalties for plagiarism. Kuther (2003) finds that 68% of students say that "ignoring strong evidence of plagiarism" is "not ethical under any circumstances."
Conspicuously absent from the Keith-Spiegel et al. list of reasons for ignoring cheating is the lack of benefits for faculty of achieving a low incidence of cheating. Because there do not appear to be any benefits awarded to an instructor by others, the only benefits available are those awarded by oneself, e.g., satisfaction in doing the right thing. Those faculty who experience substantial self-awarded benefits may be willing to incur the time and effort costs of the oral exam/paper.
Conclusion
The high incidence of plagiarism indicates that effective approaches to dealing with plagiarism are not widely adopted by faculty. Part of the problem appears to be that the emotional, time and effort, and fear costs for faculty are too high for the common approaches to be effective. Given the lack of benefits for faculty of achieving a low incidence of plagiarism, new (and old) approaches to dealing with plagiarism should be considered with the costs for faculty in mind. Approaches which diminish the costs for faculty merit more attention.
