分子间力 (IMF) 的知识对于理解化学和生物系统及其在颗粒水平上的转化至关重要。在高中课程中纳入 IMF 教学，可以让学生对化学课上呈现的材料形成概念性理解，而不是简单地重述事实。本文描述了一项以学生为中心的活动，该活动是为高中生开发的，目的是辨别分子结构和沸点之间的关系，作为 IMF 的介绍。本课程的开发方式是学生必须使用数据来支持他们的结论，并且所使用的数据是专门选择的，以防止形成误解或不完整的概念。提供了有关学生和老师之间互动的详细信息，以帮助那些希望在自己的课堂上成功开展这项活动的人。这项活动和后续课程是在 250 多名高中生中进行的，其中许多人甚至是...
Knowledge of intermolecular forces (IMFs) is fundamental to comprehending chemical and biological systems and their transformations at a particulate level. Including instruction on IMFs in the high school curriculum allows for students to develop a conceptual understanding of the material presented in chemistry class as opposed to simply restating facts. Herein, a student-centered activity developed for high school students to discern relationships between molecular structure and boiling point as an introduction to IMFs is described. The lesson was developed in such a way that students must use data to support their conclusions, and the data employed were chosen specifically to prevent misconceptions or incomplete conceptions from forming. Details regarding the interactions between students and the teacher are provided to help those looking to employ this activity in their own class successfully. This activity and follow-up lesson were implemented with over 250 high school students, many of whom, even a y...
