形成性评价在营养与食品卫生学中的实施效果分析

目的：分析形成性评价在营养与食品卫生学中的实施效果。方法选择2010级预防医学专业1班55名学生为对照组，2班56名学生为实验组，分别进行终结性评价和形成性评价，通过考试成绩和调查问卷分析结果。采用SPSS 17.0软件分析，计量资料采用x±s表示，采用t检验、字2检验、秩和检验、一元线性相关分析进行统计分析，检验水准α=0.05。结果实验组学生实验成绩、期末成绩明显高于对照组学生成绩，两组比较差异有统计学意义（P值分别为0.001、0.000）；实验组学生总评成绩更接近负偏态分布，平均成绩为89分明显高于对照组平均成绩79分（P〈0.01），且平时成绩与期末成绩呈正相关（r=0.865，P〈0.001）。调查问卷结果显示，学生认同形成性评价在教学过程中的应用。结论形成性评价提高了营养与食品卫生学教学质量。

Analysis on implementation effect of formative assessment in nutrition and food hygiene

Objective To analyze the implementation effect of formative assessment in nutri-tion and food hygiene. Methods 55 students of Class One from grade 2010 majoring in preventive medicine were taken as the control group, with 56 students of Class Two as the experimental group.The control group used the summative assessment , while the experimental group used the formative assessment. Results were analyzed by course examinations and questionnaire surveys. SPSS 17.0 soft-ware was used and the measurement data were expressed by x±s. Statistical analysis was performed using t test, test, rank sum test, a Yuan linear correlation analysis, with the level of test α=0.05. Results The experimental scores and final scores of experimental group students were significantly higher than the control group and the difference was statistically significant（P values were 0.001, 0.000）. The experimental group＆#39;s overall result is closer to the negative skewed distribution. The ex-perimental group＆#39;s average score of 89 points is significantly higher than the control group＆#39;s average score of 79 points（P〈0.01）, and the usual results and the final results were positively correlated（r=0.865, P〈0.001）. The survey indicated that the students recognized the application of formative assess-ment in teaching process . Conclusion Formative assessment can help improve the teaching and learning quality in nutrition and food hygiene.
