摘要
"数据分析与实验设计"课程具有理论复杂、概念抽象等特点,环境科学专业学生掌握难度大。文章提出了以"应用+实践"为导向、理论教学与实践教学并重的教学模式,在教学内容、教学方法和考核方式上进行了相应改革。结合科研项目设计了与教学内容结合紧密的实践案例,涉及抽样方法、异常值检验、概率分布、假设检验、大小比较、相关分析等20个知识点,覆盖课程教学大纲中约70%的内容。新教学模式使学生大大提升了学习兴趣,强化了对基本概念和方法的理解和应用,锻炼了解决问题的能力,提高了创新能力和综合素质。
The"Data analysis and experimental design"course is characterized by its complicated theories and abstract concept,and therefore learning of this course is a challenging work for students majoring in environmental science.According to the characteristic of environmental science,a teaching model oriented by"Application+practice"and emphasized by interaction of theory and practice is developed.Teaching contents,methods and evaluation methods of this course are also reformed.A practice case closely related with teaching contents is carefully designed based on a specific research project,covering 20 knowledge points,including sampling method,outlier test,probability distribution,hypothesis test,correlation analysis,and so on.The new teaching model has greatly enhanced students’interest in learning,strengthened their understanding and application of basic concepts and methods in this course to solve problems,and improved their innovative ability and comprehensive quality.
