本实验是高中生物新教材(人教版)必修3《稳态与环境》的探究实验,要求学生能够讨论出实验探究方案和制定出实验计划,通过7d的连续培养观察,探究酵母菌种群的数量变化,统计数据,绘制变化曲线,最终能建构数学模型,这对学生的知识基础、实验能力和运用数学解决生物学问题的能力都提出了较高要求。通过此实验培养学生的探究问题的能力、实验能力和思维能力。经过实际的实验教学,笔者对本
This experiment is a high school biology new teaching material (PEP) compulsory 3 “steady state and environment” research experiment, require students to discuss the experimental exploration program and to develop a pilot program, through the 7d continuous culture observation, to explore the yeast population The number of changes in the statistical data, draw the curve of change, and ultimately to build a mathematical model, which the students knowledge base, experimental ability and the ability to use mathematics to solve biological problems have put forward higher requirements. Through this experiment to develop students’ ability to explore problems, experimental ability and thinking ability. After the actual experimental teaching, the author of this
