Atomic orbitals represent an essential construct used to develop chemical bonding models, upon which other more advanced chemistry topics are built. In this article, we share a series of active-learning activities and a gamified approach to develop students' representational competence about atomic orbitals and to engage students in learning the properties of atomic orbitals. These properties are essential for understanding an array of fundamental concepts such as penetration and shielding, relationships such as periodic trends, and models used to describe chemical bonding. The activities employ an inquiry-based approach to engage students in exploring the relationship between atomic orbitals' spatial properties and quantum numbers. The activities guide students to collect data to verify periodic trends and construct electronic configurations. The activities utilize Orbital Explorer Web site for visualization, comparison and analysis of atomic orbitals. The Orbital Explorer Web site is described in a related Technology Report. The activities and the game are suitable to be conducted in both in-person and remote-teaching settings.
原子轨道是用于构建化学键模型的重要概念，其他更高级的化学主题都建立在此基础之上。在本文中，我们分享了一系列主动学习活动以及一种游戏化方法，以培养学生对原子轨道的表征能力，并让学生参与学习原子轨道的性质。这些性质对于理解一系列基本概念（如钻穿效应和屏蔽效应）、周期趋势等关系以及用于描述化学键的模型至关重要。这些活动采用探究式方法，让学生参与探索原子轨道的空间性质与量子数之间的关系。活动引导学生收集数据以验证周期趋势并构建电子构型。活动利用“轨道探索者”网站对原子轨道进行可视化、比较和分析。“轨道探索者”网站在一份相关的技术报告中有描述。这些活动和游戏适合在面对面教学和远程教学环境中开展。
