The sequence Physics-Chemistry-Biology implies that continuous collegial professional development for teachers is essential. Teachers (including those in mathematics) should meet regularly to plot the evolution of their courses, their essential coherence, and the inclusion of stories that illustrate how science works.
物理-化学-生物学的学习顺序表明对教师进行持续的大学专业发展非常重要。教师们（包括数学教师）应该经常碰面商讨对他们课程的改进、课程之间重要的相干性以及如何在课堂上讲一些描述科学是怎样工作的故事。教师们需要时间一起讨论。
