教学目标
Course Objectives
This course introduces the biological characteristics of popular model organisms, including mouse, chick,
zebrafish, Drosophila, C.elegans, and Sea urchin, and great achievements obtained with these animal models.
This course aims to provide a broad look at development integrating classical experiments with modern molecular
and genetic techniques. We will explore the basic body plan of the embryo and how organs are formed, with
special emphasis on vertebrate models. Lectures will focus on experimental design and discovery through
experiments. In-class activities, problem sets, and exams will similarly require that students put themselves in the
shoes of a scientist at the bench and design experiments to test certain hypotheses or evaluate hypothetical
experiments.
Students are expected to achieve:
1. Learn how to choose an appropriate model organism.
2. Understand the fundamentals and key questions of developmental biology.
2
3. Train themselves and apply what they learn to their own research.

教学方法及授课创新点
Teaching Methods and Innovations
课堂讲授时注意引导学生就重要生物学现象展开讨论,从中发掘归纳出生物学问题,并寻找相应的
解决问题的思路和方法,比较在不同实验技术背景下研究思路的差异。鼓励学生积极提出自己的想法
不要轻易接受一种现成的理论。学生们将选择经典的科学问题,就最新进展做口头报告
