通过对本着从具体的生活场景中选择一位普通教师，并对其教学反思的行为进行实地考察的原则来选择的考察对象的研究发现，已有研究所提出的一些反思内容、方法和影响因素在教学实践中有所体现，诸如对教学过程、教学环境、自身的特点和优缺点等方面的反思；采用个人备课、教后记、学年总结、论文、阅读理论文献、与学生谈话、同事、网络等教学反思方法；学校教学环境、生存压力、个人信念等教学反思的影响因素。

Researchers expected that the gene responsible would vary from lake to lake.

That single preexisting variant--rare in the open ocean--allowed the fish to adapt rapidly to a new environment.

研究者希望不同的湖之间相关的基因有所差别，可是，他们发现每一组搁浅的棘鱼都通过同样的机制失去了它们的装甲：一种罕见的DNA缺陷影响了一个涉及皮内骨和牙齿生长的信号分子，这一个先前存在的变数——在开放的海洋中很少存在——使得鱼可以迅速适应新的环境。
