A model for making decisions about ethical dilemmas in student assessment     

Robert L. Johnson  Jin Liu  Yin Burgess 《Journal of moral education》2017,46(2):212-229

In this mixed-methods study we investigated the development of a generalized ethics decision-making model that can be applied in considering ethical dilemmas related to student assessment. For the study, we developed five scenarios that describe ethical dilemmas associated with student assessment. Survey participants (i.e., educators) completed an online survey to express their decision-making process when faced with ethical dilemmas relating to student assessment. Based on the literature and the educators’ written responses to the scenarios, elements to consider in an ethics decision-making model related to student assessment include the following: (1) the critical incident giving rise to the ethical dilemma; (2) identification of the conflict elements; (3) decisions about the ethicality of the elements; (4) justification of the decisions; (5) implications; and (6) alternative suggestions. This model offers guidance to educators in considering the dimensions of an ethical dilemma in assessment prior to making a decision.  相似文献

Investigating academic dishonesty among Chinese undergraduate students: does gender matter?     

Yinxia Zhang  Hongbiao Yin 《Assessment & Evaluation in Higher Education》2018,43(5):812-826

The high rate of academic dishonesty reported among Chinese college students has created challenges for practitioners in both domestic and Western universities. Following two contrasting yet complementary scholarly approaches, this study explored the relative importance of predictors indicative of students’ intention to cheat (moral attitude, subjective norm and penalty enforcement) and of their educational preparedness for academic integrity (integrity engagement) in explaining academic dishonesty, with an emphasis on gender differences. We administered a questionnaire survey to a sample of 2009 Chinese undergraduate students. The results indicated that moral attitude and integrity engagement were the major predictors, that subjective norm accounted for marginal variations of academic dishonesty, and that the influence of penalty enforcement was insignificant. Some gender differences on both the mean score and effect levels of the four predictors were revealed. The effects of grade, year and area of study on academic dishonesty (and particularly their joint effects with gender) were noteworthy. These findings are discussed relative to the results of prior studies and the Chinese context.  相似文献
