Assessment Design and Cheating Risk in Online Instruction - 0 views

  • It would be a mistake to minimize the problem of cheating in f2f classes. Four stylized facts emerge from a survey of the literature on cheating in f2f undergraduate courses. First, cheating by college students is considered widespread (McCabe and Drinan 1999). For example, estimates from five studies of college students reporting having cheated at least once during their college career range from 65% to 100% (Stearns 2001), and Whitley (1998) reports an average of 70% from a review of forty-six studies.   Second, cheating by college students is becoming more rather than less of a problem. Estimates from five studies of the percentage of college students cheating at least once in their college career have been steadily rising over the period 1940 to 2000 (Jensen, Arnett et al. 2002). A study administered in 1964 and replicated in 1994 focused on the incidence of serious cheating behaviors (McCabe, Trevion et al. 2001). This study reported that the incidence of serious cheating on written assignments was unchanged at 65-66%, but the incidence of serious cheating on exams increased from 39% to 64%.  Third, the format of assessment is correlated with cheating. Whitley (1998) reviewed 107 studies of cheating by students over the span of their college courses (published since 1970), and reported that from 10 studies a mean estimate of 47% for cheating by plagiarism, from 37 studies a mean estimate of 43% for cheating on exams, and from 13 studies a mean estimate of 41% for cheating on homework. Fourth, student characteristics of age and GPA are negatively correlated with cheating.  Whitley (1998) reviewed 107 studies on college cheating (published since 1970), and found 16 studies reporting a small negative correlation between GPA and cheating and 10 studies reporting a negative correlation between age and cheating.
  • In the growing literature about online instruction there are two opposing views on the integrity of assessments. One view is that cheating is as equally likely to occur in the f2f format as in the online format of instruction.
  • The alternative view is that proctored exams are the only way to protect the integrity of grades by guaranteeing both that a substitute is not taking the exam and that students are not working together on an exam.

  • Summary and Conclusions This study reports three principle findings.  First, from a survey of student opinion it is reported that 59% believe that the frequency of cheating is the same in both the online and the f2f instructional format. The proportion is significantly greater than 50% at the .05 level. It is also reported that the responses to the question of cheating and instructional format are significantly different depending on whether the student came from an online class or a f2f class, but only at a p-value of .1060.  Recalling the literature review in Table 1, which reported mixed findings by previous empirical studies, an interesting implication for future research is whether student experience with each instructional format influences student perceptions of differences in the frequency of cheating. Second, on proctoring and the frequency of cheating on essay exams and multiple choice exams, it is reported that roughly half of the respondents perceive unproctored assessments as having greater cheating risk than the same assessment in a proctored format, and half think they have equal cheating risk. These findings are consistent with the conventional perception that in a side by side comparison of two courses with comparable content and predominately multiple choice exam assessments, the course with unproctored exams is viewed as having greater cheating risk. Third, in our analysis of assessment design in 20 online courses it is reported that 70% base roughly half the course grade on unproctored multiple choice exams.     These findings imply that online courses, which have unproctored multiple choice exams, can reduce perceived cheating risk by proctoring some of their multiple choice exams without significantly altering the original mix of assessment types. Gresham’s Law suggests that online courses debased by assessment designs with high cheating risk will displace courses with relatively lower cheating risk. Institutions of higher education tone deaf to the issue of proctoring online multiple choice assessments may understandably find other institutions reluctant to accept these courses for transfer credit.  The benefit of proctoring is not without cost.  A proctored exam limits the spatial and the asynchronous dimensions of online instruction, which may have been the core reason the student enrolled in the online. These costs can be mitigated to some extent by early announcement of the time and date of the exam, by allowing for some flexibility of time of exam, and by permitting use of alternate certified proctoring centers. The costs to individual instructors are formidable but there are potentially significant economies of scale to be realized by integration of online courses with an existing system that administers proctoring of exams for f2f classes.  Proctoring of some multiple choice exam assessments will reduce cheating risk. The elephant in the room, however, is the cheating risk on non-exam unproctored assessments (for example term papers, essays, discussion, and group projects). These are widely used in f2f instruction and, as online instruction evolves, will likely become equally widely used in online courses. These assessments are valuable because they encourage learning by student-to-student and student-to-faculty interactions, and because they measure Bloom’s higher levels of learning. These assessments have higher cheating risk than proctored multiple choice exams. These assessments, more so than multiple choice exams, challenge the ability of faculty and administration to inspire students to behave ethically and to refrain from academic misconduct.
