Investigating Student Understanding of Energy in High School Chemistry Courses

这项应用研究的目的是研究专门为提高学生对能源的理解而开发的化学课的影响。能量是科学中一个普遍存在的概念，在化学、生物和物理中被用来解释许多观察到的现象；然而，在高中化学课程中，它往往没有得到强调。本项目的目标是研究构建能量概念的方法，以促进学生对这一重要主题的理解。具体地说，该计划是为了确定对稳定性的强调是否会提高学生对能源的理解。这项研究的结果将最终指导“以化学为生”高中化学单元关于能源的发展，并为“ChemQuery”评估系统开发关于能源的问题。

The purpose of this applied research is to study the impact of chemistry lessons developed specifically to improve student understanding of energy. Energy is a pervasive concept in science that is used in chemistry, biology and physics to explain many observed phenomena; however, it is often not emphasized in high school chemistry courses. The goal of this project is to examine ways to frame the concept of energy to foster student understanding of this important topic. Specifically, the plan is to determine if an emphasis on stability improves student understanding of energy. The results of this research will ultimately guide the development of a "Living by Chemistry" high school chemistry unit on energy and the development of questions on energy for the "ChemQuery" assessment system.
