摘要：This research aims to identify and measure the effectiveness of business ethics courses on student Moral Reasoning. In-depth interview and a pilot test were conducted to examine the understandability of the experimental instrument. Quasi-experimental methods were conducted on students who join a business ethics course. One hundred twenty-two participants were valid from the manipulation check of pre-test and post-test. Paired T-Test was used to test the score between pre-test and post-test. Moral reasoning was measured using a defining issue test (DIT) to categorise High and Low Moral Reasoning on Participants. The result shows no difference in moral reasoning score between pre-test and post-test on a student who joins the business ethics course. This study finds that student moral reasoning does not improve by joining a business ethics course at university. These results imply that we should evaluate and re-examine the business ethics course syllabus for future research.
