Plagiarism or not? investigation of Turnitin®-detected similarity hits in biology laboratory reports.

In undergraduate biology laboratory courses, laboratory reports can be a useful tool for teaching scientific writing, integration of source material, and information literacy; however, these teaching objectives are at times undermined by students' plagiarism. Laboratory instructors often use similarity-matching software to detect plagiarism in laboratory reports, yet similarity hits detected with such software remain poorly characterized. In the upper division molecular biology laboratory course described here, Turnitin® routinely detected dozens of similarity hits in laboratory reports. To determine whether this abundance of similarity hits was indicative of widespread plagiarism, we analyzed similarity hits detected in 255 laboratory reports written by 135 students. Only a small minority of Turnitin® similarity matches were problematic, but over half of the laboratory reports contained at least one problem with incorporation of scientific sources (e.g., laboratory manual and scientific articles). We identified four common types of such writing problems: patchwriting, technical parroting, copying, and falsification of sources. In 18% of the laboratory reports, we detected an alarmingly superficial use of primary literature. Most of the source incorporation problems did not rise to the level of plagiarism. As a result of this study, we recommend changes in scientific writing instruction and a transition to laboratories providing more authentic research experiences. © 2019 International Union of Biochemistry and Molecular Biology, 47(4):370-379, 2019.

A systemic analysis of cheating in an undergraduate engineering mechanics course.

Cheating in the undergraduate classroom is not a new problem, and it is recognized as one that is endemic to the education system. This paper examines the highly normative behavior of using unauthorized assistance (e.g., a solutions manual or a friend) on an individual assignment within the context of an upper division undergraduate course in engineering mechanics. The findings indicate that there are varying levels of accepting responsibility among the students (from denial to tempered to full) and that acceptance of responsibility can lead to identification of learning and necessary behavioral changes. The findings have implications for institutions and engineering faculty, in particular the need for consistent academic integrity education and the teaching of professional integrity and ethics.

Academic integrity in a mandatory physics lab: the influence of post-graduate aspirations and grade point averages.

Research on academic cheating by high school students and undergraduates suggests that many students will do whatever it takes, including violating ethical classroom standards, to not be left behind or to race to the top. This behavior may be exacerbated among pre-med and pre-health professional school students enrolled in laboratory classes because of the typical disconnect between these students, their instructors and the perceived legitimacy of the laboratory work. There is little research, however, that has investigated the relationship between high aspirations and academic conduct. This study fills this research gap by investigating the beliefs, perceptions and self-reported academic conduct of highly aspirational students and their peers in mandatory physics labs. The findings suggest that physics laboratory classes may face particular challenges with highly aspirational students and cheating, but the paper offers practical solutions for addressing them.
