一系列在线活动强调实验的设计和解释。化学概念是抽象的，很难与现实世界的经验联系起来。出于这个原因，高中和大学化学课程侧重于一组具体的问题类型，这些问题类型在教科书和标准考试中已经成为经典。这些问题类型强调化学的核心符号和计算工具的发展。尽管这些工具可能构成了潜在的程序性知识基础，从这个基础上可以接近“真实的东西”，但当在显示其实用性或与科学核心思想联系的背景下教授时，它们可能会表现为一个脱节的技巧袋（1）。
A collection of online activities emphasizes the design and interpretation of experiments. Chemistry concepts are abstract and can be difficult to attach to real-world experiences. For this reason, high-school and college chemistry courses focus on a concrete set of problem types that have become canonized in textbooks and standard exams. These problem types emphasize development of the core notational and computational tools of chemistry. Even though these tools may form the underlying procedural knowledge base from which the “real stuff” can be approached, when taught out of contexts that show their utility or that draw connections to core ideas of science, they can appear as a disconnected bag of tricks (1).
