辩论型教学在食品毒理学课程中的应用探讨

Discussion on the application of debate based teaching in food toxicology course

目的探讨辩论型教学在食品毒理学课程中的应用及效果。方法以食品毒理学课程中的“外源化学物的致突变作用”章节为例，在我校2014级（37人）、2013级（49人）卫生检验专业本科生的教学中；将2014级学生作为对照组，采取传统授课；将2013级学生作为实验组，采取辩论型教学。两组学生教学结束后，均接受该章节随堂测验。此外，对实验组学生开展教学满意度与自身学习表现问卷调查。采用SPSS16．0对两组学生测验成绩行t检验。结果实验组学生测验平均成绩高于对照组[（7．24±0．66）vs．（6．35±0，82），t=5．575，P=0．000]。针对实验组学生发放调查问卷49份，回收有效问卷49份；大部分学生认为，通过辩论型教学激发了对该门课程的学习兴趣，增强了自身各项能力与素质。结论辩论型教学应用于食品毒理学课程的效果较好，可锻炼学生综合能力。

Objective To explore the application effect of debate teaching in food toxicology teaching. Methods Taking the chapter of ＂mutagenie effect of exogenous chemicals＂ in the course of food toxi- cology as an example, totally hygiene quarantine specialty undergraduate students from March 2015 to July 2016 in our school for the course of Grade 2014 （n=37）, Grade 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, quizzes 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. T test was conducted on the test scores of two groups of students by SPSS 16.0. Results The average test score of the students in the experimental group was higher than that of the control group [（7.24±0.66） vs. （6.35± 0.82）, t=5.575, P=0.000]. 49 questionnaires were issued to the students in the experimental group, and 49 valid questionnaires were recovered. The majority of students believed that the debate teaching method aroused their interest in the course of learning and enhanced their abilities and qualities. Conclusions The application of debate teaching in food toxicology teaching has good effect, and it can train students＇ comprehensive ability.
