Changing answers on objective tests in a university food and nutrition course was investigated. Responses to 4% of the questions were changed, with a 3:1 ratio of wrong-to-right to right-to-wrong changes. Most students changed at least one answer on each test. More students gained than lost points by changing answers, with a 3:1 ratio of those gaining to those losing. Sex and changing answers usually were not related. Students with the highest grades made the fewest changes. Teachers should advise students to change answers on objective tests in food and nutrition if, after reconsideration, another answer seems better.
对大学食品与营养课程中客观测试题答案的更改情况进行了调查。4%的问题答案被更改，答错改对与答对改答错的比例为3:1。大多数学生在每次测试中至少更改了一个答案。更改答案后，得分增加的学生多于得分减少的学生，二者比例为3:1。性别与更改答案通常无关。成绩最高的学生更改答案的次数最少。教师应建议食品与营养课程客观测试中的学生，如果经过重新思考后觉得另一个答案更好，就更改答案。
