目的 探索辩论型教学在食品毒理学教学中的应用效果。 方法 以食品毒理学课程中的“外源化学物的致突变作用”该章节内容为例,选取2015年3月至2016年7月在我校进行该课程学习的2014级(37人)、2013级(49人)卫生检验专业本科学生进行辩论型教学和传统教学比较。2014级学生作为对照组采取传统讲授法;2013级学生作为实验组采取辩论型教学。两组教学分别结束后,进行随堂测验对学生本次课程的学习进行考核评分。此外,辩论型教学组的学生在随堂测验结束后就学生对辩论型教学方式的满意度、以及学生自身在教学实施中的学习表现进行问卷调查。测验成绩平均分以均数±标准差表示,两组差异采用独立样本t检验进行统计分析。随堂测验各小题正确率、问卷调查各结果均以百分比表示。 结果 辩论型教学组学生理论成绩显著高于对照组[(7.24±0.66) vs. (6.35±0.82),t=5.575,P<0.0001]。辩论型教学组调查问卷共发放49份,回收49份,回收率100%。大部分学生认为通过辩论型的教学方式增加了其对该门课程学习的兴趣、还可提高学生各方面的能力,比如团队凝聚力、口才和胆量等。 结论 辩论型教学应用于食品毒理学的教学效果明显优于传统讲授法,此外还可提高学生各方面能力的锻炼,提示今后可将辩论型教学运用于食品毒理学的教学中
Abstract
Objective:To explore the application effect of debate teaching in food toxicology teaching. Methods:Taking the chapter of mutagenic effect of exogenous chemicals in the course of food toxicology as an example
totally hygiene quarantine speciality undergraduate students from March 2015 to July 2016 in our school for the course of grade 2014 (n=37)
2013 (n=49) were selected as subjects and conducted debate teaching and traditional teaching comparison. The students of grade 2014 took the traditional teaching method as the control group
while the students of grade 2013 took the debate teaching method as the experimental group. After the teaching of two groups
quiz were used to evaluate the students' learning of this course. In addition
the students in the debate teaching group were investigated by the questionnaire of the students' satisfaction with the teaching method and the learning performance of the students in the teaching practice at the end of the quiz. The average scores of quiz were expressed as Mean±SD
the difference between the two groups was statistically analyzed by independent sample t test. The correct rate of each question and the results of questionnaire are expressed as percentage. Results:The theoretical results of the debate teaching group were significantly higher than those of the control group [(7.24±0.66) vs. (6.35±0.82),t=5.575,P<0.0001]. A total of 49 questionnaires were issued by the debating teaching group
and the recovery rate was 100%
which was 49. The majority of students believed that debate teaching method not only increase their interest in the course of learning
but also improve the ability of students in all aspects
such as team cohesion
eloquence and courage
etc.. Conclusions:The application of debate teaching in food toxicology teaching is obviously superior to traditional teaching method and can also improve the students' ability of various aspects
