Understanding the organizational framework and predictive powers of the periodic table is paramount in preparing students for success in chemistry. An interactive classroom activity was developed to engage students as they analyzed and evaluated the repeating trends in physical and chemical properties of elements displayed on the periodic table. This activity transforms the class into a “representative” periodic table, with each student portraying a unique element as they analyze their relation to their elemental neighbors, evaluate statements regarding their periodic peers, and explore of the power of periodicity present within the periodic table. Prior to this activity, the students correctly answered just over 10% of the questions asking them to evaluate periodic trends, while after the activity the students correctly answered over 50% of the questions covering the same content. Student feedback was positive and highlighted the interactive and engaging qualities of the activity. The People Periodic Table activity is flexible enough to be used in nearly any introductory chemistry class to enhance student engagement and learning with respect to the periodic table’s organization, predictive powers, and trends.

人民周期表：从事化学入门课程的学生的框架

了解化学元素周期表的组织框架和预测能力对于培养学生在化学领域的成功至关重要。开发了一种交互式课堂活动，以吸引学生，他们分析并评估了元素周期表中显示的元素的物理和化学特性的重复趋势。这项活动将班级转变成一个“代表性”元素周期表，每个学生在分析他们与基本邻居的关系，评估关于其周期性同伴的陈述并探索元素周期表中存在的周期性的力量时，描绘出一个独特的元素。在进行此活动之前，学生正确回答了超过10％的问题，要求他们评估定期趋势，活动结束后，学生可以正确回答超过50％的相同内容的问题。学生的反馈是积极的，并强调了活动的互动性和吸引力。元素周期表活动具有足够的灵活性，几乎可以在任何化学入门课程中使用，以增强学生对元素周期表的组织，预测能力和趋势的参与和学习。
