不同实验策略对学生动物学实验效果的影响

The Influence of Different Experimental Strategies for Zoology Experimental Result of Students Initial Study

采用仅施后测的准实验设计,对毕节学院2010级生物科学专业2班和1班进行了不同实验教学策略对动物学实验效果的对比试验。结果表明:实验组的后测成绩与对照组的后测成绩差异极显著(p<0.05且p<0.01),说明采用改进型动物学实验教学策略能明显提高学生动物学实验成绩。此外,观察发现:实验班与对照班在实验动作技能的规范熟悉程度、实验解剖成功率、实验作业完成情况、实验态度、形态结构的辨认测验、实验目标实现程度、实验材料准备、合作学习表现等方面也存在一定差异。建议对传统的动物学实验策略进行有效改革,以提高学生的动物学实验学习水平。

Used quasi experimental design that only effects after measuring. And make a different experi-mental policy on zoology experimental effect of comparison test between 2010 level bio 2 class and 2010 level bio 1 class. The esuhs indicates us that：It is different between experimental group of Hou measuring results and control group of Hou measuring results. And the difference is very significantly （p〈0.05 and p〈0.01）. So we can learn that it can improve students zoology experimental results clearly to used the improved type zoolo-gy experimental teaching policy of improved type. In addition, through the study I found that there are some differences between experimental group and control group. For example, the experimental skills of familiarity, the success frequency of dissection,the accomplish situation of housework, the job attitudes, and the tests of morphological identification, the accomplish of test objectives,the prepared of experimental material,the dis-play of cooperative learning and so on. So I recommend that to improve the experimental strategies for tradition reform of zoology, to raise the level of students＇ experimental of studv zoology.
